Cabinet Installation Cost: What You Pay a Pro to Set Them

When somebody asks me what cabinet installation costs, they usually want one number. I understand why, but I can't hand you one honestly — and anybody who does before they've looked at your kitchen is guessing. Setting cabinets is finish work. The boxes are only the starting point. What you actually pay for is the labor to make a run of factory boxes read as one continuous, level, plumb line of cabinetry against walls and floors that are never as flat as the boxes assume. Here's what drives that number, and what you should expect to see when a real quote lands in your inbox.

Why there's no per-foot price for setting cabinets

Crown and baseboard have rough per-linear-foot ranges because they're repetitive — same profile, same wall, same motion down the room. Cabinets aren't like that. A ten-foot galley with four base boxes and four uppers is a completely different day than a ten-foot run of the same footage broken up by a range, a corner, a tall pantry, and a window that eats one upper. The count of individual boxes matters more than the wall length, because every box has to be leveled, shimmed, screwed to its neighbor, and fastened back to framing on its own. That's why cabinet install is quoted per job, not per foot. If you want to understand how trades price labor generally, I break it down in our finish carpentry cost guide.

Box count, and whether they show up assembled

The single biggest driver is how many boxes there are and what condition they arrive in. Assembled cabinets from a shop or a semi-custom line show up as finished boxes — I set them, shim them, and fasten them. RTA (ready-to-assemble) flat-pack is a different job entirely, because before anything gets hung, somebody has to build every box: cam locks, glue, square them up, clamp, let them set. That assembly labor is real and it goes on the clock. If you supply your own cabinets, the number and type change the estimate before I ever touch a wall — I cover how that works in our guide to professional installation of homeowner-supplied cabinets.

• Number of boxes — bases, uppers, tall units, each set individually
• Assembled vs. RTA flat-pack — flat-pack adds build-out labor before hanging
• Tall pantries and appliance garages — heavier, fussier to plumb and secure
• Island or peninsula runs — often fastened from the floor with cleats, more layout

Wall condition, out-of-square, and the scribe work nobody sees

This is where the quotes separate the pros from the price-shoppers. Your walls are not plumb, your floors are not level, and your corners are not ninety degrees — that's true in almost every house, and it's especially true in older East Tennessee homes. Cabinets have to be set to the floor's high point, then shimmed up from there so every box across the run sits dead level; if you start at the low end, the far cabinets float off the floor. Where a finished end or a filler meets a wavy wall, that edge gets scribed — hand-fit to the wall's actual shape so there's no gap to caulk over. Fillers between the last cabinet and a wall or the ceiling get scribed and cut the same way. None of that shows in the finished kitchen, which is exactly the point, but all of it is labor, and worse walls mean more of it. A quote that ignores wall condition is a quote that's going to grow mid-job.

Filler, crown, light rail, and the trim that finishes the run

The bare boxes aren't the finished product. Filler strips close the gaps at walls and around appliances. Toe-kick gets cut and fit along the base. Then there's the detail trim on top: crown molding tying the uppers into the ceiling and light rail underneath them to hide undercabinet lighting. Crown on cabinets is real finish carpentry — coped inside corners, mitered outside corners, scarfed on long runs, all worked at height over the boxes — and where that crown is priced as its own molding line it falls in the usual range of roughly $5–$12 per linear foot depending on profile and paint- vs. stain-grade. Everything else — fillers, light rail, toe-kick, panels — is job-specific labor that lives in the cabinet install line, not a per-foot rate.

Coordination: countertops, appliances, and sequencing

A cabinet install rarely stands alone, and the coordination is part of what you're paying for. The boxes have to be set dead level and locked before a countertop fabricator can come template, because a template taken off cabinets that aren't right will hand you a counter that isn't right. Appliance openings — range, dishwasher, cooktop, panel-ready fridge — have to hit spec so the units actually drop in. Getting the sequence and the tolerances correct is a real part of the job, and it's a big reason I recommend one finish crew owns the cabinets, the trim, and the coordination rather than splitting it across people who each blame the other. If you're weighing that, our post on one finish crew vs. multiple subs lays out why it matters.

What a real quote should show you

When you get a bid from me or anyone worth hiring, it should name the drivers, not hide them. Expect the box count, whether they're assembled or flat-pack, an honest note on wall and floor condition, and separate lines for the finish details like crown, light rail, and fillers. That transparency is the whole point of a quote — it's how you tell a number built on your actual kitchen from a number pulled out of the air. If a bid is one lump sum with no breakdown, ask for one.
