Trim is where flooring projects quietly gain a second budget line. Baseboards are priced by the linear foot, not the square foot, and the spread between the cheapest MDF and stain-grade oak is ten to one. This guide breaks baseboard and trim cost down per linear foot — material grades, installation, and painting separated — plus totals for real room sizes.
All figures are per linear foot of trim unless a total says otherwise. Measure the wall, not the floor: a room’s baseboard length is its perimeter minus door openings, plus about 10% for cuts and miters.
Baseboard and trim cost per linear foot
Typical US prices, checked November 2026. Material prices are for standard 3.25–5.25 in baseboard profiles; labor varies mainly by region.
| Cost item | Typical cost per linear ft |
|---|---|
| MDF baseboard, primed (material only) | $0.50 – $1.50 |
| Finger-joint pine, paint-grade (material only) | $1.00 – $2.50 |
| PVC baseboard (material only) | $1.00 – $2.50 |
| Solid oak, stain-grade (material only) | $2.00 – $5.00 |
| Professional installation labor | $1.50 – $3.50 |
| Professional painting (caulk, fill, finish coats) | Add $0.75 – $1.50 |
| Total, professionally installed, unpainted | $2.00 – $6.00 |
| Total, professionally installed and painted | $3.00 – $7.50 |
The material grade is the decision that drives everything else. MDF is the budget default for painted trim — smooth, consistent, and cheap — but it swells if it soaks up water, so it is a poor choice against bathroom tile or in damp basements. Finger-joint pine costs more and takes paint just as well with better impact resistance. PVC shrugs off moisture entirely for wet rooms. Solid oak is the stain-grade option: you are paying for grain that will show, and it is usually paired with stained rather than painted finishes. Taller profiles cost more per foot within every grade — a 5.25 in board uses more material than a 3.25 in one and reads as a deliberate upgrade.
Total cost by project size
| Trim length | DIY materials (MDF, paint-grade) | Professionally installed and painted |
|---|---|---|
| 50 linear ft (one bedroom) | $25 – $75 | $150 – $375 |
| 100 linear ft (a few rooms) | $50 – $150 | $300 – $750 |
| 200 linear ft (a main floor) | $100 – $300 | $600 – $1,500 |
DIY totals are the trim itself. Add a flat $30 – $60 for paint, caulk, wood filler, and nails for a typical project — those supplies barely scale with length, which is why DIY trim is so cheap per foot. Removing old baseboard first adds roughly $0.50 – $1.50 per linear ft if a contractor does it, and shoe molding or quarter round — the small strip that covers the gap where baseboard meets a new floor — adds $0.30 – $0.80 per linear ft in material when a flooring project calls for it.
Painted vs unpainted: what actually changes
Almost all paint-grade baseboard is sold primed, not painted — the flat white factory coat is a primer, and it still needs finish coats. That one fact explains most of the price gap between quotes:
- Installed, unpainted: $2.00 – $6.00 per linear ft total. The boards are up, nail holes may or may not be filled, and painting is on you.
- Installed and painted: $3.00 – $7.50 per linear ft total. The extra $0.75 – $1.50 per foot buys caulking the top edge, filling holes, and finish coats — the fiddly work that makes trim look finished instead of installed.
- DIY painting: the paint itself is nearly free per foot — trim paint covers a lot of linear feet per gallon — so the real cost is an afternoon with a brush. The Interior Paint Cost per Square Foot (2026 Guide) prices the paint side, and the Paint Calculator will tell you a quart is plenty for most trim jobs.
One sequencing tip either way: paint the boards once before installation, then touch up after. It is faster than painting everything in place and keeps paint off the new floor.
What changes the cost
- Profile height and detail. Taller, multi-step profiles cost more in every material and take longer to cope at corners.
- Corners and returns. Rooms with many inside and outside corners, bay windows, and short wall segments cost more per foot than the same length in long straight runs.
- Old trim removal and wall condition. Pulling old baseboard, scraping old caulk, and fixing damaged drywall edges all add labor before the new boards go up.
- Staircases and curved walls. Rake baseboards on stairs and flexible trim on curves are specialist work, priced well above straight-run rates.
DIY vs hiring a carpenter or painter
For 100 linear ft, DIY materials and supplies run about $80 – $210 all-in against $300 – $750 professionally installed and painted — a saving of a few hundred dollars. Baseboard is genuinely DIY-able with a miter saw and a nail gun, and the learning curve is mostly one skill: coping inside corners instead of mitering them, which looks better and forgives out-of-square walls. Hire it out when trim is part of a flooring install the same crew is already doing (the marginal cost drops), for stair runs, or when you want the caulk-and-paint finish to disappear completely — that finish work, not the boards, is what you are really paying for. Note that new floors often force the trim question anyway: the LVP Flooring Cost per Square Foot (2026 Guide) and other flooring guides assume baseboards come off or shoe molding goes on.
FAQ
How much baseboard do I need for a 12 × 12 room?
The perimeter is 48 linear ft; subtract about 3 ft for a door and you need roughly 45 ft of board. Buy 50 linear ft to cover cuts, miters, and one mistake — boards come in 8, 12, and 16 ft lengths, so plan the lengths against your longest walls to minimize joints.
Is MDF or wood baseboard better?
For painted trim in dry rooms, MDF is fine and the cheapest option — it is smoother than pine and never shows grain. Choose finger-joint pine where boards take kicks and vacuum bumps, PVC anywhere that gets wet, and solid wood only when the finish will be stained.
Does primed baseboard need to be painted?
Yes. Primer is a bonding and sealing coat, not a finish — it scuffs easily, holds dust, and yellows unevenly. Budget the finish coats (or the $0.75 – $1.50 per linear ft to have them done) into every baseboard project.
How much does it cost to replace baseboards in a whole house?
A main floor runs about 200 linear ft, so $600 – $1,500 professionally installed and painted for paint-grade trim, or $100 – $300 in MDF plus supplies to do it yourself. Stain-grade oak throughout can double or triple the professional figure.
What is shoe molding, and do I need it?
A small quarter-round or shoe profile nailed at the base of the baseboard, costing $0.30 – $0.80 per linear ft in material. It exists to cover the expansion gap at the edge of a floating floor — if new LVP or laminate is going down and the baseboards are staying, shoe molding is usually how the edge gets finished.
