New flooring can make the old baseboards look worse than they did before. Or you may have one swollen section beside a doorway and wonder whether the whole room needs new trim.
So painted MDF baseboard costs $6 to $9 per linear foot, material and labor combined, in ProBrothers’ Delaware County and Main Line pricing. That is a Pennsylvania contractor’s range for standard trim, not a national average.
I will walk you through the boards, fitting and painting, then the extra work that can turn a small trim job into a bigger repair. These US prices were checked October 18, 2026.
Baseboard Prices per Linear Foot
The installed range above covers 3- to 4-inch painted MDF. Taller boards, different profiles and stain-grade wood need their own quotes. The retail examples below are boards only, before tax, delivery and fitting.
Those pine examples bracket different sizes and profiles at one Florida seller. The Cherokee hardwood examples use the same 5-inch profile. Compare the material and profile as well as the price per foot.
For painted rooms, compare MDF with primed pine in the profile you actually want. If you want visible wood grain, ask about unfinished hardwood and its finishing cost before buying the trim.
Take a sample of the existing baseboard if you are replacing only part of a room. Match its height, thickness and shaped top, especially where it meets door casing that will stay.
Measure the Walls Before Pricing the Room
Baseboard follows the walls, so floor area is the wrong measurement. Add the wall runs that need trim, including closets if they are part of the job, and subtract door openings.
A 12-by-10-foot room with one 3-foot doorway needs (12 + 12 + 10 + 10) less 3 = 41 linear feet before cutting waste. More doors or built-in cabinets change that count.
Using ProBrothers’ installed range, that example gives 41 × $6 = $246 to 41 × $9 = $369. It is a calculation, not a small-job quote; minimum charges and work outside the trim package may change it.
Buy lengths that suit the wall runs, not just the total footage. A collection of short offcuts cannot always replace one long board without adding a visible joint.
Removal, Corners and Installation Labor
A fitting price needs a clear starting point. Installing trim against bare walls is different from removing painted-in boards, pulling old nails and repairing torn drywall first.
Ask the carpenter to separate removal and disposal from new-board installation. The saved ProBrothers page does not give a separate tear-out rate, so I would not treat it as a guaranteed inclusion.
Inside corners, outside corners and uneven floors take fitting time. A room with lots of short wall sections can need more cuts than a simple room with the same total footage.
For uneven floors in older homes, ProBrothers describes shaping each baseboard run to fit. Ask the carpenter how the new boards will meet your floor.
If you are hiring a flooring installer and a painter separately, decide who fills nail holes, caulks the upper edge and finishes the joints. Otherwise both quotes can leave that work for someone else.
Would Painting the Existing Boards Be Enough?
Sound trim with scuffs or tired paint may only need preparation and repainting. Northern Star Painters publishes $1.50 to $3 per linear foot for baseboard painting in Upperville, Virginia.
Using Northern Star’s range, 100 feet would be 100 × $1.50 = $150 to 100 × $3 = $300. Ask how much cleaning, filling and caulking your particular boards need before treating that as a final quote.
Do not add painting again to an installed package that already includes the finished surface. Also, a factory-primed board still needs a finish coat; primed and painted are different stages.
Water-Damaged Baseboards Need the Cause Fixed First
Swollen trim beside a shower, exterior door or appliance deserves a closer look before replacement. Find out where the moisture entered and whether the wall or floor behind the board is also affected.
The EPA’s moisture guide calls for fixing leaks and drying materials completely. It also advises against painting or caulking over moldy surfaces. New trim cannot solve an active water problem.
If the damage reaches the wood beneath your flooring, our subfloor replacement guide covers that separate repair. A soft floor needs more than a new board along its edge.
What Homeowners Paid or Were Quoted
These older accounts show why the scope matters. They include one installation quote range and two accounts of broader trim replacement.
- On Houzz, November 26, 2018, Thomas Tzeng reported installation quotes of $1,500 to $3,000 for about 380 linear feet in the San Francisco Bay Area. The post does not spell out painting or removal.
- On DC Urban Moms, May 6, 2021, at 11:05, a homeowner who had replaced trim in several homes reported usually spending about $10,000 for 2,500 square feet. Nail-hole filling and painting were extra.
- On DC Urban Moms, May 5, 2021, at 11:32, a homeowner reported $14,000 for a project replacing baseboards and window and door trim. It was a wider job than replacing baseboards alone.
Questions About Replacing Baseboards
Should New Baseboards Match the Old Height?
They do not have to, but shorter boards can expose an unpainted strip or damaged wall above them. Taller boards need to fit neatly beside the existing door casing and other trim.
Can Stained Baseboards Be Painted White?
Northern Star offers this work. Its process includes cleaning, sanding, stain-blocking primer and two coats of finish paint.
