How Is a Custom Millwork Estimate Built, and What Drives the Price Most?
A real custom millwork estimate isn't a single price per linear foot. It's built from the actual project: engineering and drawings, materials, shop labor for each cabinet and drawer, finishing, hardware, and installation. The things that move the number most are how dense and complex the cabinetry is (which is why kitchens cost more per foot than most built-ins), the door style, and the finish.
People usually ask us for a price per linear foot first. It's a fair question, and we answer it: our custom cabinetry typically runs $500 to $1,200 per linear foot, plus installation, and the most involved kitchens go above that. But a per-foot number hides almost everything that makes one project cost more than another. Here's how we actually build an estimate at BUILT, and what changes it.
Why one per-foot number doesn't tell you much
"Linear foot" sounds precise, but shops don't even agree on how to measure it. Some count the length of the wall. Some count base and wall cabinets separately and add them together. Some count a corner cabinet as two feet, because it takes two feet of work. Some include appliance openings and some don't. Two quotes at the same "price per foot" can describe very different amounts of cabinetry.
It also treats every foot as equal, and they aren't. A foot of wall cabinet with one door is a simple box. A foot of base cabinet with three drawers means three drawer boxes, three sets of slides and three fronts that all have to line up. A foot of tall pantry with rollouts is more again. Cabinetmakers have argued about this on trade forums for years, and the honest shops land in the same place: per-foot pricing is a way to start a conversation about budget, not a way to price a project.
So we use it the way it's useful. At the low end of our range is a full-overlay slab door in wood veneer with a matte clear finish. At the high end is inset Shaker with a color-matched satin finish, integrated pulls and LED-lit drawers. Where your project sits depends on the choices below. We lay out the range in detail in How Much Does Custom Cabinetry Cost in Tampa?
What actually goes into a BUILT estimate
We've tracked our labor hours on every project for thirteen years, so we know what each part of a project takes in our shop. Because engineering, fabrication, finishing and installation all happen in-house, our estimate follows the same path the project does.
Engineering and drawings. Every project is modeled in 3D and drawn as full shop drawings before anything is cut. Pre-production usually takes about a month: a first meeting, field measurements on site, initial concepts, two to three weeks of shop drawings, then finish samples for approval. That time is real work, and it's where most expensive mistakes get caught.
Materials. Cabinet boxes are 3/4-inch plywood. Painted doors and panels are MR50, a high-density, moisture-resistant MDF. Stain-grade work is kiln-dried hardwood, or veneer over a stable core for wide panels. The species and veneer you choose change this line more than anything else in it.
Shop labor. This is counted cabinet by cabinet: every box, drawer, door, panel, filler and scribe. Drawers, tall cabinets, corners and appliance panels each take more time than a plain door cabinet.
Finishing. Everything is finished in our shop with a UV-protectant finish, and every surface is sealed, including backs and edges. Paint and stain aren't the same amount of work, and some finishes need more coats and more sanding between them.
Hardware. Blum soft-close hinges and slides are our standard. Specialty hardware (lift-up mechanisms, pocket doors, pull-outs, integrated lighting) is priced item by item.
Installation and project management. Our own crew installs, and we price installation per home: the distance from our shop, how complex the install is, and how accessible the site is. That includes scribing to walls, leveling on uneven floors, and any site logistics.
On the estimate itself, each room is its own line, and that line covers everything in the room. In a kitchen, that means crown, panels, fillers and trim along with the cabinets. Installation is a separate line.
The biggest cost drivers
1. Density and complexity: why kitchens cost more
A kitchen packs more work into each foot than almost anything else we build. Look at what's in a typical kitchen run: drawer stacks, a sink base built for plumbing, a dishwasher panel, a refrigerator or freezer with integrated panels, a range hood surround, a tall pantry, fillers and end panels on every exposed side, and a lot of coordination with the countertop, appliance and plumbing trades.
Compare that with a wall of library shelving or a closet run of open hanging space. The footage might be the same, but the kitchen has several times the parts, hardware and precision. That's why a kitchen almost always costs more per linear foot than a built-in, and why drawer-heavy kitchens cost more than door-heavy ones.
If you're trying to manage cost, this is the first place to look. Swapping a drawer stack for a door and pull-out shelves, or letting one side of a run stay simple, changes the number more than switching species.
2. Door style
The door is the largest visible part of the cabinetry, and door construction makes a big difference in labor.
Slab doors are the simplest to make, but stain-grade slabs need good veneer and careful grain matching, and that isn't cheap.
Frame-and-panel doors (Shaker and its variations) add joinery and more parts per door.
Inset doors sit flush inside the cabinet face frame instead of covering it, with a small, even gap all around. Every door and drawer front has to be fitted to its opening. In our shop, inset Shaker runs about 50 percent more than slab, on the whole per-foot price. We don't price doors separately from the cabinets they hang on. What you get for it is a look that can't be ordered from a catalog: we set the frame width, the Shaker rail width and the trim to suit your kitchen, so the proportions belong to that room.
Profiles, beads, applied moldings and glass doors each add more time.
3. Finish
Finish is the part of the price people see least on paper and notice most in five years.
Paint is usually more work than a clear finish over stain-grade wood: primer, sanding, multiple color coats and a finish that has to stay crisp on every edge.
Stain and clear finishes depend on the species. Some woods take stain evenly. Others need extra steps so they don't blotch.
Sheen matters more than people expect. The higher the sheen, the more every flaw shows, so high-gloss finishes take more sanding and more coats.
Specialty finishes (glazes, color-matched samples, custom colors) add sampling and spray time.
There's no single percentage for finish. Sheen, whether the piece is stained or painted, and the material underneath all move the price, and they work together.
In Florida, a finish also has to deal with humidity and sun. That's why everything we build is shop-finished, sealed on all surfaces, and protected against UV fading near big windows. A finish that's cheaper to apply can cost you more when doors crack at the joints or colors fade in a west-facing room. We go deeper into this in Which Cabinet Materials Hold Up in Florida Humidity?
4. Material and species
Moisture-resistant MDF for painted work is an economical, very stable choice. Stain-grade species vary widely: white oak, rift-sawn white oak and walnut each cost differently, and rift-sawn or book-matched veneers cost more again because more of the log is wasted to get that grain. The box underneath stays the same whatever you choose: 3/4-inch plywood.
5. Site and installation
The same cabinetry can take very different installs. Tall ceilings mean stacked uppers and more crown. Older homes in South Tampa and Palma Ceia often have walls and floors that are far from straight, so there's more scribing and shimming. Condo projects in downtown St. Pete come with freight elevator reservations, restricted work hours and building insurance requirements, and all of those take time. That's why installation is priced per home rather than per foot.
How we use the estimate to find the right number
Because our pricing system is built on those tracked hours, we can update a proposal quickly and show you several options side by side: the same kitchen in slab and in inset, painted and in clear-finished oak, with and without lit drawers. Cost can move a lot between those versions, and we'd rather you see that than guess at it.
We're open about what's driving the number. If the budget and the design don't meet, we'll value-engineer with you: keep inset where you'll see it every day and simplify a secondary room, trade some drawer stacks for doors with rollouts, use LED lighting where it matters most. What we wouldn't change is the box material or the finish quality, because those decide how the cabinetry looks in ten years.

Where the value actually is
A lot of what you pay for in custom work never shows in a photo:
Drawings you approve before anything is built. Appliance clearances, plumbing, outlets and panel-ready specs are solved on paper instead of on site.
Materials chosen for this climate. Plywood boxes, moisture-resistant MDF, kiln-dried lumber and sealed surfaces are what keep cabinetry looking right in ten years instead of two.
One team from drawing to install. When the people who drew it also build, finish and install it, fewer things fall between trades.
Follow-up. Within the first year we come back at no charge to reset every door, drawer and reveal, fix anything that sticks, tighten hardware and make small touch-ups. Wood settles into a Florida home over its first summer, and that visit is built into the price.
When two quotes are far apart, it's usually because they describe different things. Our 12 questions to ask a custom cabinetmaker will help you find out which parts differ.
How to get an accurate number sooner
The more we know, the closer our first number will be to the final one. The most useful things to bring:
Architectural or interior design drawings, even preliminary ones
Appliance models, especially panel-ready refrigerators and dishwashers
A sense of door style and finish (photos are fine)
Ceiling heights and any known site conditions, such as a condo building's rules
A budget range. Knowing it lets us suggest where to spend and where to simplify.
With that, we can give you a working range early and a firm price once drawings are done.

Frequently asked questions
Why do custom cabinet quotes vary so much per linear foot?
Shops measure linear feet differently, and a foot of cabinetry can mean anything from a simple shelf unit to a stack of drawers with integrated appliance panels. Door style, finish, materials and installation conditions all change the cost, so the per-foot figure only means something once you know what's included.
Why are kitchens more expensive than other built-ins?
Kitchens pack more parts into each foot: drawer stacks, appliance panels, sink and plumbing bases, tall pantries and finished end panels, plus coordination with countertops and appliances. A library wall or closet run of the same length has far fewer parts and less hardware.
Do inset cabinets cost more than overlay?
Yes. In our shop, inset Shaker runs about 50 percent more than slab on the whole per-foot price, because every door and drawer front has to be fitted to its opening with a consistent gap. In exchange, the frame, rail and trim widths can be set for your room.
What's the best way to lower the cost of custom cabinetry without hurting quality?
Simplify where it matters least. Replacing some drawer stacks with doors and pull-outs, choosing a simpler door profile, or keeping secondary rooms plain saves more than downgrading materials, and it keeps the box construction and finish that decide how long the cabinetry lasts.
