Cabinet Installation

Leveling and hanging stock, semi-custom, and custom cabinets — matched to your material and done by a vetted crew, with a clear written quote. Below: exactly what the work involves, what drives the cost, and the spec that makes it last.

Cabinet installation is the engineered process of fastening a run of base, wall, and tall boxes dead-level and plumb, anchored through their backs into wall studs, so doors and drawers align and the cabinetry carries its load for decades. Two facts decide whether a cabinet run looks built-in or bolted-on, and almost nothing else does: whether every box is shimmed to a single level reference line, and whether each cabinet is screwed into solid framing rather than drywall. Hit a continuous level line and land every screw in a stud and even mid-grade cabinets read as custom; miss either and premium boxes sag, doors swing open on their own, and face frames split at the screws. Get a free consultation and a written, itemized scope from a vetted installer before a single box is hung — that document is where a lasting kitchen is decided.

Cabinet Installation Is a Layout-and-Anchoring Job First, a Box Job Second

The door style and finish everyone notices matter least to how the run performs. What separates cabinets still square in fifteen years from ones that rack in three is the measured layout and the anchoring done before the first box touches the wall.

The Wall and Floor Decide What the Cabinets Can Do

No wall is plumb and no floor is level, so the room dictates what is possible and the cabinetry only decides what it looks like inside that constraint — which is why a credible installer reads the space before quoting:

  • A base run set to a sloping floor instead of a level line leaves countertops that pitch and doors that drift open.
  • A wall cabinet screwed to drywall alone pulls free under the weight of dishes and tears a hole on the way down.
  • A box hung tight to a bowed wall without shims racks the face frame, and the doors never sit flush again.

None of those are product defects — they are layout and anchoring failures, the most common reason a new kitchen disappoints. Settle the surfaces around them under the countertops hub and the flooring hub once the boxes are right.

The Order of Operations Never Changes Across Cabinet Types

Find level, find the studs, hang the boxes, then hang the doors. That sequence holds across Shaker, flat-panel, solid-wood, MDF, and custom cabinetry. The structural work is always the same: find the highest point of the floor and strike a level line from it, locate and mark every stud, set and shim each box to the line, fasten through the back rail into framing, draw boxes together so face frames sit flush, then adjust doors and drawers last. The style choice happens inside those facts, not before them.

The Cabinet Readiness Gate: Six Checks Before Any Box Goes Up

Before a single cabinet is fastened, a competent installer runs the whole run through the same six-check gate. Each check has a measurable target, each is a documented cause of cabinet failure when skipped, and a layout that fails any one is not ready. Call it the Cabinet Readiness Gate: pass all six and the run has the foundation to last; fail one and you are buying a future callback.

1. Level reference line
The installer finds the highest point of the finished floor with a laser or long level, then strikes a continuous level line around the room — typically the standard 34-1/2" base-cabinet height — that every base box is shimmed up to. Setting boxes to the floor instead of to a level line is the source of pitched countertops, doors that drift open, and uneven reveals across the run.
2. Stud location and anchoring
Studs are found and marked across the entire run, because cabinets hang on framing, not drywall. Wall boxes are fastened through a solid back rail with 2-1/2" to 3" cabinet screws driven into each stud the box crosses. A wall cabinet anchored to drywall alone — even with anchors — eventually pulls loose under loaded weight; landing screws in studs is the single check that keeps an upper on the wall.
3. Wall and corner condition
Walls are checked for plumb and bow with a level, and inside corners for square, before layout, because a bowed wall or an out-of-square corner forces filler and scribe decisions. The high spot of a bowed wall sets where boxes can sit flush; an unread wall is why face frames end up racked and adjacent doors never line up.
4. Filler, scribe, and clearance planning
Before boxes go up, the installer confirms filler strips at walls and at appliances, the scribe needed against out-of-square corners, and the clearances doors and drawers need to clear handles, appliances, and adjacent runs. Cabinets set without filler and scribe allowance are why a run binds at a wall or a dishwasher door hits a cabinet pull.
5. Appliance and plumbing rough-in match
The rough-in is verified against the cabinet plan — the range opening, the sink-base cutouts for supply and drain, the dishwasher and refrigerator openings, and any electrical — before the boxes that frame them are set. A sink base hung before the drain location is confirmed, or a range opening built a half-inch tight, is a tear-out, not an adjustment.
6. Box squareness and ganging
Each box is checked square at delivery and as it is set — measuring corner-to-corner diagonals — and cabinets are drawn together (ganged) face-frame to face-frame, or side-to-side for frameless, with the fronts flush before final fastening. A run fastened to the wall before the boxes are ganged flush is why door gaps wander and a countertop seam falls on a step in the cabinet line.

Three of these six — the level line, stud anchoring, and squareness — are the corners cut on a rushed install, because they cost the measured, patient hours a fast crew skips, yet every one is checkable on site. That is why the gate is non-negotiable.

Want the layout and anchoring done right before the boxes go up?

We match you with a vetted installer who strikes a level line, finds every stud, and puts the layout in a written scope — before a single cabinet is fastened to your wall.

Cabinet Installation Specifications & Standards

The numbers that gate a cabinet install are published and testable — from the construction of the box itself, through the standard dimensions every kitchen shares, to the fastening and clearance figures that decide whether doors and drawers work.

Cabinet Box Construction

The box — the carcass behind the door — is what actually carries the load and holds square, so it is the spec that decides how a cabinet survives years of weight and use. How it is built varies most in two places: the material of the box and how the joints are made.

Box Material: Plywood vs. Particleboard

The carcass is built from one of two engineered panels, and the choice drives weight capacity, moisture tolerance, and how well the box holds a screw. The construction, not the door, is where cabinet quality is decided.

Plywood Box Construction

A plywood box is built from cross-laminated wood veneers, typically 1/2" to 3/4" thick, and it is the stronger carcass: it holds screws far better, resists sagging under loaded shelves, and tolerates a damp sink base or a humid bath where particleboard swells. It is the reason a plywood-box cabinet weighs more and costs more than a particleboard equivalent — and the spec to ask for in a sink base or a bathroom vanity.

Why Box Material Decides Screw Hold

Screw hold is the practical reason box material matters at install: a cabinet hangs by screws driven through its back, so the panel those screws bite into determines whether the box stays on the wall under load. Plywood's cross-laminated layers grip a screw and resist pull-through; particleboard's loose-bonded chips strip and crumble around a screw far sooner, which is why a heavy upper on a particleboard box is the one most likely to sag at the back rail or pull free over time.

Particleboard Box Construction

A particleboard carcass — compressed wood chips bonded with resin, usually faced with melamine — is the lower-cost box found in most stock and many semi-custom lines. It builds a flat, stable, smooth-faced box and performs well in a dry run, but it is heavier, weaker at the screw, and intolerant of standing water: a leak under a particleboard sink base swells and delaminates the panel where plywood would shrug it off.

Box Joinery and the Back Rail

How the box is joined and how its back is built decide whether it stays square and whether it can be anchored. Quality boxes use dadoed and glued joints — the side panels captured in grooves — rather than staples alone, and a full 3/4" hanging rail or a solid plywood back gives the install screws something real to bite. A thin, stapled hardboard back with no solid rail is the construction that cannot be anchored properly no matter how good the crew.

Standard Cabinet Dimensions

Kitchen cabinetry runs on standard dimensions, and an installer works to them because countertops, appliances, and fillers all assume them. Base cabinets stand 34-1/2" tall (a finished 36" with countertop) and run 24" deep; wall cabinets are commonly 30", 36", or 42" tall and 12" deep, mounted with the standard 18" of backsplash clearance above the counter. Cabinet widths step in 3" increments. A run built off these numbers is why a stock countertop and a standard range drop in without a fight.

Overlay, Reveal, and Door Gap

Overlay is how much of the face frame a closed door covers, and it sets the look and the gaps. Full overlay leaves only a thin reveal between doors for a modern, frameless-like face; partial (standard) overlay shows more frame; inset doors sit flush inside the frame with a precise, even gap all around. Whatever the overlay, the install target is a consistent reveal — even gaps between every door and drawer across the run — which is the visible payoff of a level line and ganged-flush boxes.

Cabinet Fastening & Clearance, by Element

The table below collects the recognized figures a competent installer works to. These are representative industry standards — the cabinet maker's printed instructions always govern, and where they are stricter, the stricter number wins.

ElementWhat's setRecognized standardTypical figure
Base cabinet heightBox height before countertopIndustry kitchen standard34-1/2" (finished 36" with top)
Base cabinet depthFront-to-wall depthIndustry kitchen standard24" deep

Cabinet width incrementBox widths offeredIndustry kitchen standardSteps of 3"
Door & drawer revealGap between frontsCabinet-maker spec by overlayConsistent reveal across the run
Range & appliance openingsRough opening width/heightAppliance spec sheetPer the appliance's published rough-in

The lesson is that almost every dimension here is set by a published standard or a spec sheet, not by feel — which is why a run measured to these numbers drops countertops and appliances in cleanly, and a run guessed by eye fights every one. Size your own kitchen first with the cabinet cost calculator so you can read a quote critically.

Cabinet Construction Types and How Each Installs

How the cabinet is built — framed or frameless — is as consequential to the install as the door, because each construction hangs, gangs, and gaps differently. The two mainstream constructions, plus the install-defining hardware, decide how a run goes up and how it lives.

Framed vs. Frameless Construction Compared

The matrix below is the decision behind the door: face-frame and frameless boxes differ in access, how they fasten together, and how doors mount.

TraitFramed (face-frame)Frameless (full-access)
Box frontSolid-wood face frame on the box edgeNo frame — door covers the full box edge
Interior accessFrame narrows the opening slightlyFull-width opening, maximum access
How boxes gangScrewed face-frame to face-frameScrewed side-panel to side-panel
Hinge typeFrame-mount concealed (or face-frame) hingeFrameless concealed clip-on hinge
Door overlayPartial, full, or inset on the frameFull overlay by design
Common inMost U.S. stock & semi-custom linesEuropean and modern flat-panel lines

Framed Cabinets: Face-Frame Construction

A framed cabinet carries a solid-wood face frame across the front edge of the box, and that frame is both the strength and the install surface: boxes gang together cleanly by screwing through adjoining face frames, and the frame gives doors a stable mounting edge. The frame slightly narrows the opening, so drawer boxes and roll-outs are a touch smaller than the cabinet width — the trade for a forgiving, robust box that is the U.S. standard and the easiest to scribe to an out-of-square wall.

Frameless Cabinets: Full-Access Construction

A frameless (full-access) cabinet has no face frame — the doors mount directly to the box sides and cover the entire edge, giving the widest opening and a clean, modern face. Boxes gang side-panel to side-panel, which demands a dead-flat, plumb run because there is no frame to absorb a bow; the reveals between full-overlay doors are tight, so any box set out of plane shows immediately. It is the more exacting install and the standard for European and contemporary kitchens.

The Hardware That Defines the Install: Hinges and Slides

Two pieces of hardware decide how a finished cabinet feels, and both are adjusted at the very end of the install. Concealed hinges — hidden European cup hinges — mount inside the door and box and adjust in three directions (in/out, up/down, left/right), which is how an installer dials every door to an even reveal; cheaper exposed or non-adjustable hinges cannot be tuned the same way. Soft-close undermount drawer slides ride beneath the drawer box on full-extension ball-bearing or roller tracks and pull the drawer shut on a damper; they are why a quality drawer glides out fully and closes without a slam, where a side-mount epoxy slide neither extends fully nor self-closes. The hardware is the difference a homeowner touches every day.

Should You Install New Cabinets, or Reface or Repair What You Have?

New installation is not the default — it is the right call only when the existing boxes cannot be saved or the layout has to change. Walk the decision in order; each branch eliminates the paths that do not fit, and what survives is the honest answer.

  1. Are the existing cabinet boxes structurally sound? Open a door and check: are the carcasses square, are the backs solid and anchored, is the material dry and intact? If the boxes are racked, water-damaged, delaminating, or were never anchored properly, they cannot be saved — new installation is the path. If they are sound, refacing or repair is on the table.
  2. Is the layout staying the same? If you are keeping the footprint — same cabinet locations, same openings — and the boxes are sound, refacing with new doors and veneer is the value play. If you are moving the sink, changing the island, or reconfiguring the run, you are installing new cabinets regardless of box condition, because the layout drives it.
  3. Is the problem the finish, or the boxes? If the boxes are sound and the layout works and only the look is dated, you do not need new cabinets at all — painting or refinishing changes the color for a fraction of the cost. New installation for a purely cosmetic problem is money spent on boxes you already had.
  4. Do the doors and drawers just not work? Sagging doors, blown hinges, broken slides, and loose boxes are usually a repair, not a replacement — failed hardware and a few racked boxes can often be fixed for far less than a new run. Reserve new installation for when the carcasses themselves are gone.
  5. Confirm the install scope for the surviving path. If new installation is the answer, the scope is the full Readiness Gate — level line, stud anchoring, filler and scribe, appliance rough-in match, and ganged-flush boxes. Compare the cabinets against the room under the cabinets hub before ordering.

Run honestly, this tree often returns refacing or repair rather than full installation — and an installer who recommends a tear-out for sound boxes is the red flag.

Why Cabinets Sag, Rack, and Drift Open — and How the Install Stops It

The most common cabinet failures trace back to level, anchoring, and squareness, and all are preventable at install — each paired below with its mechanism, cause, and named prevention.

Sagging and Pull-Away: An Anchoring Failure

A wall cabinet that sags at the back or pulls away from the wall is an anchoring failure: the box was screwed to drywall, or into too few studs, and loaded weight slowly tore the fasteners out. The prevention is the Readiness Gate check — fasten through a solid back rail into every stud the box crosses with proper cabinet screws, never into drywall anchors alone, so the framing carries the load the dishes put on it.

Racked Boxes and Wandering Gaps: A Level-and-Shim Failure

When doors no longer line up and the reveals between them wander, the boxes are racked — set to a sloping floor or a bowed wall without shims, so the carcasses twisted out of square. That is a level-and-shim failure: the install skipped the continuous level line or the shimming behind each box. The prevention is striking the level line first and shimming every box plumb and flush to it before fastening, so the face frames sit in one plane and the gaps stay even.

Doors That Drift Open: An Out-of-Plumb Failure

A door that swings open on its own was hung on a box that is not plumb — gravity pulls the unbalanced door toward open. It points back to a base set to the floor instead of to a level line, or an upper hung against a bowed wall without correction. Plumbing the box at install and fine-tuning the concealed hinge afterward removes it; a door that still drifts after hinge adjustment means the box itself is out of plumb.

Binding Doors and Drawers: A Clearance and Squareness Problem

The last common failure — a door that hits a handle or appliance, or a drawer that rubs and won't close — is a clearance and squareness problem, caught at the Readiness Gate. Planning filler and scribe, ganging boxes flush, and confirming appliance clearances before fastening removes it. If cabinets have already failed, the path is diagnosis-first cabinet repair — and if the boxes themselves are gone, new installation rather than a patch.

Common Cabinet Installation Mistakes, Consequences, and Prevention

Most cabinet failures are the same handful of shortcuts, each with a predictable consequence and a known prevention. Naming them is how you spot a corner being cut before it is hidden behind a countertop.

MistakeWhat it causesThe prevention
Setting boxes to the floorPitched countertops, doors that drift open, uneven revealsStrike a continuous level line from the floor's high point and shim every box to it
Anchoring to drywall, not studsWall cabinets sag and pull away under loaded weightScrew through a solid back rail into every stud with 2-1/2"3" cabinet screws
Skipping shims behind boxesRacked carcasses, wandering door gaps, split face framesShim each box plumb and flush behind every fastener before tightening
No filler or scribe at wallsRuns that bind at a wall and doors that hit an out-of-square cornerPlan filler strips and scribe to the wall before boxes are ordered and set
Ignoring appliance rough-inRange or dishwasher openings too tight — a tear-out, not a fixVerify every opening against the appliance spec sheet before framing it
Hanging boxes before ganging flushStepped fronts, wandering gaps, countertop seams on a stepDraw boxes together face-to-face and confirm fronts flush before final fastening
Overtightening into a face frameSplit frames, stripped screws, boxes drawn out of squarePre-drill and snug to flush, not crush, with the right screw and clamp pressure

Every row is a documented callback trigger — which is why "we set to a level line and anchor into studs, in writing" is the most valuable sentence in a cabinet quote.

Choosing the Cabinet Style and Material for the Room — and the Spec That Rates It

The best cabinet for a room is matched to its use, its moisture, and the look you want, and every choice has a published trait that predicts how it holds up — which is why buying on the showroom door alone lands a beautiful kitchen on a weak box.

Door Styles and What They Demand

The door sets the look and a little of the upkeep, so match the style to how the room lives:

  • Shaker is the five-piece recessed-panel door — the most popular style in the U.S. and a transitional look that suits nearly any kitchen; its square inside edges collect a little more dust than a slab and take paint or stain equally well.
  • Flat-panel (slab) is a single flat door, minimalist and frameless-friendly, and the easiest face to wipe clean; it shows the substrate, so veneers and acrylics matter, and it is the default for modern and full-overlay runs.
  • Solid wood doors and face frames are repairable and refinishable for life, but they expand and contract with humidity — the reason a painted solid-wood Shaker can hairline at the panel joints in a dry winter.
  • MDF doors are dense and uniform with no grain to telegraph under paint, and they resist seasonal movement, making them the ideal painted door; they are heavier than wood and damaged by standing water.
  • Thermofoil wraps an MDF door in a heat-sealed vinyl film for a seamless, easy-clean face, but the film can peel near heat sources over time — keep it clear of an un-vented oven or toaster.

Matching the Box and Style to the Room

Room context overrides the showroom. A kitchen wants a plywood sink base and a durable, cleanable door; a bathroom vanity demands moisture-tolerant box material in a humid, splash-prone room; a laundry room needs utility storage rated for damp and detergent; a garage wants heavy-duty boxes for tools and gear; a home office or closet system favors a configurable build. Pick the box and door for the room first. To compare options spec-for-spec, the material comparison tool lines them up.

What Actually Drives the Cost of a Cabinet Installation

A cabinet quote is not a flat per-box rate; the headline number a low bid leads with hides the items below, ranked by how much they move the total.

The Cost Drivers That Move the Total Most

  1. Cabinet grade and construction. Stock, semi-custom, and custom — and a plywood box versus particleboard — set the baseline before a single one is hung; the box construction drives more of the price than the door you see.
  2. Layout complexity and box count. The biggest labor swing. A galley of standard boxes installs fast; an L- or U-shaped kitchen with an island, corners, tall pantries, and many fillers is far more setting, shimming, and scribing.
  3. Old-cabinet removal and disposal. Tear-out is labor and haul-away is a fee — and removal often exposes wall and floor problems that change scope mid-job, which is why it belongs in the written quote up front.
  4. Wall and floor correction. Bowed walls, out-of-square corners, and sloping floors all add shimming, scribing, and sometimes wall prep — real hours a plumb, level, square room avoids.
  5. Hardware grade. Soft-close undermount slides and adjustable concealed hinges cost more than basic side-mount slides and exposed hinges, and they are installed and adjusted box by box across the whole run.
  6. Fillers, scribes, and trim. Filler strips, scribe molding, light rail, crown, and toe-kick at every wall and ceiling line add cut-and-fit labor beyond the boxes themselves.
  7. Appliance and plumbing coordination. Cutting sink-base openings, fitting around a range or refrigerator, and coordinating with plumbing and electrical add labor a simple run does not.
  8. Countertop and backsplash sequencing. Cabinets set the stage for the countertop templated on top; a run that has to be re-leveled for the countertop install costs more than one set right the first time.

Because these drivers swing so widely, the only honest number comes from an on-site assessment. Compare what moves the price across the category in our cost guides — including the detailed kitchen cabinet cost breakdown — and size your own kitchen first with the cabinet cost calculator so you can read a quote critically.

The Cabinet Installation Process, Step by Step

A professional install runs the same disciplined sequence every time, and each step exists to prevent a specific failure. The six steps below are the full arc from on-site measure to final door adjustment.

  1. On-Site Measure and Layout

    The installer verifies the field dimensions against the cabinet plan, checks walls for plumb and corners for square, confirms appliance and plumbing rough-in, and marks the layout. Scope and filler decisions are made here against the Readiness Gate — not assumed from the order — before any box is unboxed.

  2. Strike the Level Line and Find the Studs

    The installer finds the highest point of the floor and strikes a continuous level line at 34-1/2" around the room, then locates and marks every stud across the run. These two reference lines govern every box that follows — the level line for height, the studs for anchoring.

  3. Set and Anchor the Wall Cabinets

    Uppers are hung first (so base boxes don't block the work), set to the line, shimmed plumb and flush, and fastened through the back rail into each stud with 2-1/2"3" cabinet screws. Boxes are ganged face-to-face with fronts flush before the screws are driven home.

  4. Set, Shim, and Anchor the Base Cabinets

    Base boxes are set to the level line, shimmed up off the floor to it, ganged flush, and screwed to the studs and to each other. The sink base, range opening, and any tall cabinet are placed and checked against the rough-in, with fillers and scribes cut to the walls.

  5. Trim, Toe-Kick, and Filler

    Scribe molding is fit to out-of-square walls, light rail and crown run the tops, toe-kick covers the shims at the floor, and fillers close the gaps at walls and appliances. This is where the run stops looking like boxes and starts looking built-in.

  6. Hang Doors, Set Drawers, and Adjust

    Doors go on their concealed hinges, drawers ride their soft-close undermount slides, and the installer dials every hinge in three directions until the reveals are even and consistent across the run. The site is cleaned and the installer walks the kitchen with you to confirm the result before the countertop is templated.

Skip or rush any one of these six steps and the failure it was meant to prevent shows up later — which is why a vetted installer treats the sequence as fixed, not optional.

Cabinet Installation Glossary

The terms below recur in every cabinet quote, spec sheet, and warranty — each defined as its working meaning on an actual job site, so you can read a scope and judge whether it is complete.

Carcass (box)
The structural cabinet box behind the door and drawers — sides, bottom, top or stretchers, and back — that carries the load and holds square. Everything else mounts to it.
Face frame
The solid-wood frame across the front edge of a framed box that stiffens it and gives doors a mounting surface. Frameless cabinets omit it for full access.
Frameless (full-access)
A box with no face frame, where doors cover the entire front edge — the European construction that maximizes interior space and uses full-overlay doors.
Overlay
How much of the face frame a closed door covers — partial, full, or inset (flush inside the frame) — which sets the reveal between fronts and the overall look.
Reveal
The visible gap between adjacent doors and drawer fronts. A consistent reveal across the run is the payoff of a level line and ganged-flush boxes.
Concealed hinge
A hidden European cup hinge mounted inside the door and box that adjusts in three directions, letting the installer tune every door to an even reveal.
Soft-close undermount slide
A full-extension drawer slide mounted beneath the box on ball bearings that pulls the drawer shut on a damper — full reach and no slam.
Shim
A thin tapered wedge slipped behind or beneath a box to bring it plumb, level, and flush to the reference line before fastening. The reason a box on an imperfect wall still sits square.
Scribe
Trimming a cabinet edge or filler to follow an out-of-square wall or corner so the joint reads tight. The finish move that hides a crooked wall.
Filler strip
A matching strip that closes the gap between a cabinet and a wall or appliance, giving doors and drawers room to clear without hitting an obstruction.
Plywood vs. particleboard box
The two carcass materials: cross-laminated plywood holds screws and resists moisture and sag; resin-bonded particleboard is cheaper and flatter but weaker at the screw and intolerant of water.
Toe-kick
The recessed base below the bottom drawer that your feet tuck under, and the trim that covers the leveling shims at the floor line.

Standards, Warranty Conditions, and When a Permit Applies

A cabinet warranty is a contract with conditions, and most denials are not about the box — they are about how it was installed and what it was exposed to.

Warranty Conditions That Hinge on the Install

The conditions are specific: boxes installed level and plumb per the maker's instructions, anchored as specified, not modified in a way that compromises the structure, and kept within normal household humidity and away from sustained water. A cabinet hung out of level that later racks, or a particleboard sink base ruined by an un-fixed leak, is a denied claim — the install or the exposure voided it. Ask in writing that the install follow the cabinet maker's published instructions — that document is what a claim is judged against, and one more reason the cheapest quote is rarely the cheapest kitchen.

The Standards That Set the Bar

Quality cabinetry is built and tested to recognized standards. The KCMA certification program (and the ANSI/KCMA A161.1 performance standard) tests cabinets for structural load, door and drawer cycling, and finish resistance — a useful mark when comparing lines. Standard kitchen dimensions follow long-established industry practice, and an installer who works to both is why your countertops and appliances fit.

When a Cabinet Permit Is Required

Permits enter when the work goes beyond hanging boxes. Swapping cabinets in the same layout usually does not require one, but moving plumbing or electrical, relocating a sink, taking out a wall, or a larger kitchen renovation often does. A reputable installer tells you when a permit and licensed trades apply rather than working around it — and plumbing or electrical changes belong with the proper licensed trade, not the cabinet crew. When the boxes are sound and only the look is tired, the better path may be refacing or painting over a full tear-out and install.

A Real Cabinet Installation Decision

One representative scenario shows why layout decides everything: the room, not the cabinets, drove every call below.

How to Vet a Cabinet Installer

Most cabinet failures are install failures, so the installer matters more than the brand on the door. These questions separate a crew that builds kitchens to last from one that simply hangs boxes fast.

They strike a level line before setting any box
An installer who sets cabinets to the floor is building in every slope the room has. Ask how they establish height — a real answer involves finding the floor's high point and striking a continuous level line, not following the floor.
They anchor into studs, not drywall
Ask how they fasten uppers. A credible answer is screwing through a solid back rail into every stud with proper cabinet screws — not relying on drywall anchors, which is how heavy boxes pull free.
They shim and gang boxes flush before fastening
The right installer shims each box plumb and draws the fronts flush before driving screws home, so the reveals stay even. A crew that screws boxes tight to an imperfect wall and moves on is the red flag.
They plan filler, scribe, and appliance clearance up front
Ask how they handle the out-of-square corner and the range opening. Filler strips, scribe to the wall, and openings verified against the appliance spec are what keep a run from binding — and a tear-out from happening mid-job.
They handle removal, trim, and hardware cleanly
Ask whether removal and disposal are included, how toe-kick, crown, and fillers are finished, and whether they adjust every hinge and slide at the end. The reveals and the trim are where rushed work shows.
They put the scope and schedule in writing and stand behind the work
Ask for the full scope, the timeline, and the labor warranty in writing before work starts. A crew willing to name a workmanship guarantee — and to return if a box racks or a door drifts — is accountable for the install, not just the product the maker covers.

Almost always because the boxes were set to the floor instead of to a level line, so the carcasses sit at slightly different heights and twist out of square. A professional install starts by finding the highest point of the floor and striking a continuous level line at the standard 34-1/2" base height, then shims every box up to that single line so the face frames land in one plane. When boxes follow a sloping floor, the reveals between doors wander and some doors drift open on their own. The fix is to re-level and re-shim the affected boxes, then dial each concealed hinge in three directions to even the gaps. See cabinet repair if the run is already hung wrong.

Do cabinets have to be screwed into studs, or are drywall anchors enough?

Into studs — drywall anchors are not enough for a loaded wall cabinet. An upper full of dishes puts real weight on its back rail, and screws driven only into drywall slowly tear out, letting the box sag and pull away from the wall. The standard is to locate every stud the cabinet crosses and drive 2-1/2" to 3" cabinet screws through a solid back rail into that framing. If a stud doesn't fall behind a fastening point, the installer adds blocking inside the wall rather than trusting an anchor. Anchoring into studs is the single check that keeps an upper on the wall for the life of the kitchen.

What is the difference between framed and frameless cabinets at install?

A framed cabinet has a solid-wood face frame across the front edge of the box; a frameless (full-access) cabinet has none, so the doors cover the entire box edge. At install the difference shows in how boxes gang together and how forgiving the run is: framed boxes screw face-frame to face-frame and tolerate a slightly imperfect wall, while frameless boxes gang side-panel to side-panel and demand a dead-flat, plumb run because there is no frame to absorb a bow. Frameless gives more interior space and a tight, modern reveal, but any box set out of plane shows immediately. Framed is the U.S. standard and easier to scribe to an out-of-square corner.

What height should wall cabinets be mounted above the countertop?

The standard is 18" of clearance between the countertop and the bottom of the wall cabinets, which leaves room for small appliances and backsplash while keeping the shelves within reach. Base cabinets stand 34-1/2" tall and finish at 36" once the countertop is on, and wall cabinets are commonly 30", 36", or 42" tall depending on ceiling height. The installer works to these numbers because countertops, appliances, and backsplash tile all assume them. Over a range, the clearance changes to meet the hood or microwave manufacturer's spec, which is usually higher than the standard 18 inches.

Why does my base cabinet rock, and how is it leveled?

It rocks because the floor underneath is not flat and the box was set down on the high spots without shims, so it bears on two corners and teeters. The correct method is to set the box to the level line, then slip thin tapered shims beneath and behind it until it sits plumb, level, and flush with its neighbors before any screw is driven home. The shims are then trimmed and hidden under the toe-kick. A rocking base also throws off the countertop that lands on it, which is why leveling and shimming every box is not optional — it is the step that lets a flat countertop template against a flat run.

What are soft-close undermount slides and concealed hinges, and why do they matter?

They are the two pieces of hardware you touch every day. Soft-close undermount slides ride beneath the drawer box on full-extension ball-bearing tracks and pull the drawer shut on a damper, so it reaches all the way out and closes without a slam — unlike an old side-mount epoxy slide that neither extends fully nor self-closes. Concealed hinges are hidden European cup hinges that adjust in three directions, which is how an installer dials every door to an even reveal at the end of the job. Quality hardware is why a drawer glides and a door sits flush; it is also adjusted box by box, which is part of what a careful install includes.

Can you install kitchen cabinets over existing flooring, or does flooring go first?

It depends on the floor type and the appliances. As a rule, cabinets are set on the subfloor and the finished floor runs up to the toe-kick when the floor is a floating product like luxury vinyl or laminate — because a floating floor needs room to move and should not be pinned under the cabinet weight. With tile or glued-down floors, sequencing varies, and the appliance question matters: a dishwasher or a slide-in range needs the finished floor height accounted for so it can be installed and later removed. The right answer is decided on site against the specific floor and appliances, which is why it belongs in the written scope. See the flooring hub for how each floor type sequences.

What is a filler strip and why does my kitchen need them?

A filler strip is a matching piece of cabinet material that closes the gap between a cabinet and a wall, an appliance, or an adjacent run. Kitchens need them because no wall is perfectly straight and standard cabinets come in fixed 3" width increments, so the run rarely fits the wall exactly. Fillers also create the clearance a door or drawer needs to open without hitting a wall, a handle, or a neighboring appliance — a corner cabinet especially needs filler so its door clears the pull next to it. A run set without filler and scribe allowance is why a dishwasher door catches a cabinet, or a corner door won't open. They are planned before the boxes are ordered, not improvised at the end.

How do you install cabinets on a wall or floor that isn't square?

You scribe and shim to the imperfection rather than fight it. For an out-of-square corner or a bowed wall, the installer trims (scribes) the cabinet edge or a filler strip to follow the wall's actual line so the joint reads tight, and shims behind the box to keep it plumb despite the bow. The high point of a bowed wall sets where the boxes can sit flush, so it is found first. This is exactly why a careful installer checks every wall for plumb and every corner for square before layout — an unread wall is how face frames end up racked and adjacent doors never line up. Scribing and shimming are the finish moves that make an imperfect room look built-in.

Should I get plywood or particleboard cabinet boxes?

Plywood for anywhere that sees moisture or heavy load — especially the sink base and a bathroom vanity — and particleboard is acceptable in dry runs on a budget. A plywood carcass is built from cross-laminated veneers 1/2" to 3/4" thick that grip screws and resist sagging and swelling; a particleboard box is compressed chips bonded with resin, which is flatter and cheaper but weaker at the screw and intolerant of standing water. The practical difference shows at the sink: a leak under a particleboard base swells and delaminates the panel, where plywood shrugs it off. The box construction, not the door you see, is where cabinet durability is decided.

How long does a typical kitchen cabinet installation take?

For a standard kitchen, the cabinet setting itself is usually a one-to-three-day job depending on the layout, but that is only one phase of the project. A galley of standard boxes goes fast; an L- or U-shaped kitchen with an island, corners, tall pantries, and many fillers takes longer because each box is leveled, shimmed, ganged flush, and anchored individually. Add removal of the old cabinets, any wall or floor correction, trim and toe-kick, and final hinge and slide adjustment, and the cabinet portion of a full remodel spreads across the schedule. The countertop is templated only after the boxes are set and confirmed level, so it follows on a separate visit. A written timeline in the scope tells you exactly how the days are sequenced.

Do new cabinets come with a warranty, and can a bad install void it?

Yes on both. Quality cabinets carry a manufacturer warranty, but it has testable conditions — the boxes must be installed level and plumb per the maker's instructions, anchored as specified, not modified in a way that compromises the structure, and kept within normal household humidity and away from sustained water. A cabinet hung out of level that later racks, or a particleboard sink base ruined by an un-fixed leak, is a denied claim, because the install or the exposure voided it. Ask in writing that the install follow the cabinet maker's published instructions; that document is what a warranty claim is judged against. Many quality lines are also tested to the KCMA / ANSI A161.1 standard, a useful mark when comparing brands.
