What finish carpentry costs — and what's actually in the bid

There's no honest one-number answer to "what does finish carpentry cost" — and any sub who gives you one off a square-foot guess is either padding it or about to eat it. The finish package is priced off scope, grade, and the specific profiles and pieces in the house, and those swing the number more than the size of the floor plan does. But "it depends" isn't useful either. So here's the real version: what actually drives the cost, ballpark ranges for the common pieces, and how to read a finish bid so you can tell why two of them came back hundreds of dollars apart.

What actually drives the number

Square footage is the worst predictor of a finish bid. These are the levers that actually move it:

• Scope and linear footage. Trim is priced by the linear foot and the piece count — how much base, casing, and crown, how many doors to hang, how many cabinet runs to set. A big house with plain trim can bid under a smaller house loaded with detail.
• Paint-grade vs. stain-grade. The single biggest multiplier on trim. Stain-grade costs more for the same profile — selected stock, tighter joinery, no caulk to hide a joint. (Full breakdown in stain-grade vs. paint-grade trim.)
• Profile complexity. A single-piece crown is one run; a built-up crown is three runs to cope, stack, and align. Every added layer is more labor per foot.
• Supply vs. install. Are you furnishing the material, or is the sub supplying and installing? A supply-and-install number carries material and markup an install-only number doesn't — always state which, line by line.
• Site conditions. Nine-foot-plus ceilings, tall stairwells, walls that aren't flat or square, and tight access all add labor. The same crown costs more eighteen feet up a foyer than in a bedroom.
• Species and finish. Poplar, pine, primed MDF, white oak, and walnut aren't the same money, and site-finished vs. pre-finished changes the sequencing and the protection.

Ballpark ranges for the common pieces

With all that said, builders still want a starting point. These are general East-Tennessee ballparks for installed work on a typical job — a place to sanity-check a bid, not a quote. The only accurate price is a number bid to your actual plans and finish schedule.

• Crown molding — roughly $5–$12 a linear foot installed for standard single-piece paint-grade. Built-up profiles, stain-grade, and tall rooms run higher.
• Baseboard — roughly $3–$8 a linear foot installed, depending on height, profile, and grade. Tall built-up base with a separate cap sits at the top of that.
• Door & window casing — usually priced per opening; a typical cased opening runs in the low-to-mid hundreds installed, more for built-up or stain-grade.
• Interior doors — hanging a prehung door is a per-door labor charge; slab doors that need hinging and boring cost more per door than prehung.
• Wainscoting & paneling — a wide range by style: applied picture-frame is the value end, shaker and board-and-batten the middle, raised-panel the top. Priced by the wall, not the foot.
• Stairs and custom built-ins — these don't fit a per-foot number. A stair is priced off the rail system, baluster material, and whether it's straight, curved, or open — usually four figures and up. Built-ins and custom accents are bid per piece.

Treat any per-foot number — including these — as a starting point, not a quote. Grade, profile, ceiling height, and site conditions move them enough that the same "crown molding" line can double between two real houses.

What's actually in a finish carpentry bid

A finish bid is only as useful as it is readable. Here's what a good one spells out — and what a vague one leaves you to find out later:

• Scope by area or package. Which rooms, which services — cabinets, trim, stairs, doors, paneling — and whether it's the whole finish package or à la carte.
• Supply vs. install, line by line. What's owner-furnished and what the sub is supplying, so you're not double-paying or assuming material that isn't in the number.
• Grade and profile by area. Paint-grade throughout with stain-grade on the stair and study is a different number than stain-grade everywhere — the bid should say which.
• Allowances. Where material isn't selected yet, a clear allowance — and what happens when the real selection lands over or under it.
• Exclusions. The orphan scopes — closet shelving, exterior detail, shower and tile trim — named as in or out so nothing falls between subs. (More in our finish carpentry scope checklist.)

Why two bids for "the same job" come back hundreds apart

When you level finish bids and one's way under, it's almost never the same scope. Usually one of these is hiding in the gap:

• One bid is install-only and the other is supply-and-install.
• One assumed paint-grade where the other read stain-grade.
• One excluded the stairs, the closets, or the cabinet setting and the other carried them.
• One priced single-piece trim where the plans call for built-up.
• One is a careful coped install and the other is fast, caulk-and-go work that comes back as callbacks.

That's why the cheapest finish number is the one to read hardest. Level the scope before you level the price.
