Trim Installation Cost Calculator

In 2026, trim and molding installation typically costs $2-$12 per linear foot installed, including the trim and labor. Simple paint-grade baseboard runs $3-$6/ft, door and window casing $4-$8/ft, crown molding $6-$12/ft (more because of the overhead work and miter cuts), and wainscoting $10-$20+/ft. For a whole room, installing baseboard, casing, and crown can total a few hundred to over a thousand dollars. The main cost drivers are the linear footage, the trim type and complexity, the material (paint-grade MDF vs. stain-grade hardwood vs. custom), and whether you include painting or staining.

Crown molding is more labor-intensive than baseboard for several reasons. It's installed overhead at the ceiling line, which is slower and harder to work on than baseboard at the floor. Crown sits at an angle (spanning the wall-to-ceiling corner), so the miter and coping cuts at corners are more complex and unforgiving — inside and outside corners must be precisely fitted, and walls and ceilings are rarely perfectly square. Larger or multi-piece (built-up) crown profiles add even more difficulty. All of this means more skilled labor time per linear foot, so crown molding typically costs $6-$12/ft installed versus $3-$6/ft for baseboard.

Paint-grade trim is made from materials meant to be painted — typically MDF or finger-jointed pine — which are economical, stable, and smooth once painted, but the joints and material wouldn't look good stained. Stain-grade trim is solid hardwood (like oak, maple, or poplar) or a quality wood chosen for its grain, intended to be stained and sealed so the natural wood shows. Stain-grade material costs more and requires more careful, seamless joinery since stain reveals every imperfection. If you want painted white trim, paint-grade MDF/pine is cost-effective; if you want a natural wood look, choose stain-grade hardwood and budget for the higher material and finishing cost.

Often not — installation and finishing are frequently priced separately. Base installation covers measuring, cutting, fitting, and nailing the trim in place, plus filling nail holes and caulking in some quotes. Painting or staining is additional labor: priming and painting trim adds roughly $1-$2 per linear foot, and staining and sealing a similar amount or more. Some homeowners save money by buying pre-primed or pre-finished trim, or by painting it themselves after the carpenter installs it. This calculator lets you choose unfinished (install only), paint, or stain so the estimate reflects whether finishing is included.

For baseboard or crown molding, the linear footage roughly equals the room's perimeter — add up the lengths of all the walls. A 12×12 ft room has a 48-foot perimeter, so about 48 linear feet of baseboard (slightly less if you subtract door openings for baseboard). For door and window casing, each standard door takes about 17 linear feet of casing and each window about 14-18 feet depending on size. Always add 10-15% extra for waste from miter cuts and mistakes, more for patterned or complex profiles. This calculator works from the total linear feet you enter, so measure your runs and openings and add them up.

It depends on the situation. If you're updating to a new profile, the old trim is damaged, or it's been painted many times and looks thick and sloppy, removing it gives the cleanest result — and is usually necessary. Removal adds labor (around $1 per linear foot here) plus disposal. In some cases, new trim can go over or alongside existing trim, but mismatched profiles and built-up paint usually make removal the better choice. Removing old trim carefully also lets the installer inspect and address any wall damage behind it. For a crisp, professional look — especially with a new profile — removing the old trim first is generally recommended.

It varies with the amount and type of trim. A single room of baseboard might take a few hours, while baseboard, casing, and crown throughout a whole house can take several days. Crown molding and wainscoting are slower than baseboard because of the complex cuts and fitting. A skilled finish carpenter can typically install 100-200 linear feet of straightforward baseboard per day, less for crown or intricate work. Finishing (caulking, filling nail holes, priming, painting, or staining) adds time, often a separate day. Removing old trim and repairing walls also extends the timeline. Most single-room jobs are completed in a day.

Baseboard and simple casing are popular DIY projects if you have a miter saw, nail gun, and patience, and doing it yourself saves the labor cost. The challenge is the cuts: clean inside and outside miters (and coped joints for baseboard and crown) are what separate professional-looking trim from amateur work, and walls and corners are rarely perfectly square. Crown molding is significantly harder to cut and install well, and stain-grade work is unforgiving since every gap shows. Baseboard and basic casing are reasonable for a careful DIYer; crown molding, wainscoting, stain-grade trim, and whole-house jobs are where a finish carpenter's speed and precision are usually worth the cost.
