The cost to install casing generally runs $4-$12 per linear foot, or about $150-$450 for a standard doorway when materials and installation are included. The final price depends on casing material and profile, the amount of trim, labor rates, wall condition, and whether old casing must be removed or the new trim painted.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed casing per linear foot | $4 | $8 | $12 | Standard material and straightforward installation |
| Interior door casing | $150 | $275 | $450 | One standard doorway, both sides |
| Window casing | $100 | $225 | $400 | One average-size window, interior trim |
| Trim material only | $1 | $3 | $8 | Per linear foot; premium profiles cost more |
| Painting or staining | $1 | $2.50 | $5 | Per linear foot, depending on finish and prep |
Installed casing prices for doors and windows
Most homeowners pay $4-$12 per linear foot for casing installation, including ordinary trim and finish carpentry labor. A standard 30-by-80-inch doorway needs roughly 17-20 linear feet per side, or around 34-40 feet for both sides. At typical installed rates, that puts a two-sided door project near $150-$450; a single-sided opening often costs less.
Window casing commonly costs $100-$400 per window. A small, simple window may use 15-20 linear feet of trim, while a broad window or one with a stool and apron may require 25-35 feet. Complex corners, uneven openings, or premium wood can raise the total beyond the typical range.
For a basic interior job, budgeting about $200-$350 per standard doorway is a reasonable starting point. Estimates generally assume paint-grade trim, ordinary access, sound drywall, standard square or mitered joints, and no removal or major repair. Assumptions: U.S. midmarket labor rates, standard interior casing, normal access, and one coat of basic finish where included.
What trim, labor, and finish add to the quote
A casing quote usually separates the trim itself from measuring, cutting, fitting, fastening, filling, and finish work. Some contractors price by the opening rather than by the linear foot, so the written estimate should state whether both sides of a door are included and whether paint or old-trim removal is extra.
| Quote component | Typical price | What it covers | Common price driver |
|---|---|---|---|
| Standard MDF or finger-jointed casing | $1-$3 per linear ft | Paint-grade stock trim | Width, profile, and stock availability |
| Solid wood casing | $2-$8 per linear ft | Pine, poplar, oak, or similar trim | Species, grade, and stain-ready quality |
| Carpenter labor | $50-$100 per hour | Layout, cuts, fitting, and fastening | Local rates and corner complexity |
| Caulk, filler, and fasteners | $10-$40 per opening | Small installation supplies | Gaps, finish requirements, and quantity |
| Painting or staining | $1-$5 per linear ft | Prep and finish coat or coats | Color, wood condition, and number of coats |
| Old casing removal and disposal | $30-$100 per opening | Removal, cleanup, and disposal | Adhesive, nails, and risk of wall damage |
Labor often represents the largest part of a small installation because setup, measuring, and cleanup take time even when the trim quantity is limited. A minimum service charge of $100-$250 may apply for a one-opening job.
Ask whether the quote includes both faces, finish work, and the contractor’s minimum charge. These details can make two estimates with similar per-foot rates differ by $100 or more.
How casing width, profile, and wood species affect price
Plain, narrow casing is generally the least expensive choice. A simple 2¼-inch paint-grade profile may cost $1-$3 per linear foot for material, while a 3¼- to 4¼-inch profile often costs $2-$5. Wider trim covers more wall and may require more careful fitting around corners, which can increase both material use and labor.
MDF is a common low-cost choice for painted interior trim. It typically costs $1-$3 per linear foot and has a consistent surface, but it is less suitable for wet areas or locations likely to be hit. Finger-jointed pine is another paint-grade option, often around $1.50-$4 per linear foot. Solid poplar or clear pine may run $2-$6, while oak and other stain-grade species can cost $4-$8 or more per linear foot.
More elaborate built-up casing, backband, or custom-milled profiles can push material costs to $8-$15 per linear foot and add time for fitting. A change from a simple profile to a layered design may add $100-$400 to a multi-opening project, depending on quantity and detail.
Material selection is most consequential when the trim will be stained or must match existing woodwork. For painted rooms, a readily available MDF or finger-jointed profile can often keep the budget lower without changing the finished appearance.
How long does casing installation take per opening?
A carpenter may spend 1-2.5 hours installing basic casing around one doorway or window when the opening is prepared and the trim is on site. A two-sided door, tight miters, uneven walls, or a profile requiring multiple pieces can take 2-4 hours. Painting, caulking, and drying time may extend the project schedule even if hands-on labor remains limited.
Hourly rates commonly fall between $50 and $100, with higher rates in expensive metro areas or for specialty finish carpentry. A contractor may instead quote a fixed price per opening. For several openings in one visit, production work can reduce the per-opening rate because measuring tools, saws, and materials are already set up.
Substrate repairs can add time. If removing old casing exposes damaged drywall, loose plaster, or a gap wider than the new trim can cover, patching and sanding may add $50-$250 per opening. A shifted or out-of-square jamb may need adjustment before new casing can sit evenly.
Several openings installed together usually cost less per opening than a one-door service call. A small job may still carry a minimum charge even if the actual cutting and fitting take less than two hours.
Three casing projects with different opening sizes
A straightforward door replacement illustrates the lower-to-middle price range. For a standard 30-by-80-inch interior door, both sides use about 36 linear feet of 2¼-inch MDF casing. At $2 per foot for trim and about 3 labor hours at $65 per hour, plus $25 in supplies, the estimated total is approximately $292 before optional painting.
A medium window with a stool and apron requires more pieces and more precise cuts. If it uses 24 linear feet of paint-grade pine at $3 per foot, 2.5 hours of labor at $70 per hour, and $20 in supplies, the estimate is about $267. Painting at $2.50 per foot could add another $60, bringing the total near $327.
A premium project might include three wide door openings with 4¼-inch stain-grade oak casing. At 40 feet per opening, the total is 120 linear feet. Materials at $6 per foot cost $720; 12 hours of detailed labor at $85 per hour adds $1,020, and supplies and finish work may add $200-$350. A realistic project range is roughly $1,940-$2,090.
These examples show why opening count alone does not predict the quote. Trim grade, sides covered, finish, and the number of detailed cuts all affect the installed total. Assumptions: Straightforward access, no structural repairs, and prices before sales tax.
Regional labor rates shift casing installation estimates
Labor costs vary across the United States. In lower-cost rural and smaller-market areas, basic installation may land near $4-$8 per linear foot. Suburban and mid-sized markets often fall around $6-$10, while high-cost metro areas may reach $8-$15 for standard work, especially when a licensed or highly specialized finish carpenter is in demand.
These are broad planning ranges, not fixed regional prices. Material availability, contractor minimums, travel distance, and local housing demand can matter as much as state boundaries. A rural contractor may charge a trip fee of $25-$100 for a small job, while urban parking and access restrictions can add time or fees.
For a standard two-sided door, a quote of $180-$300 may be plausible in a lower-cost market, compared with $300-$500 in a high-cost metro. Custom profiles, stain-grade wood, and repairs can exceed both ranges. Comparing estimates is most useful when each contractor is pricing the same number of sides, linear footage, material, and finish.
Regional comparisons should focus on the complete scope, not the hourly rate alone. A higher labor rate can still produce a competitive total if the contractor completes more openings per visit or includes finishing work.
When removal, wall repairs, and paint raise the total
Removing existing casing typically adds $30-$100 per opening when the trim comes off cleanly. Old paint layers, construction adhesive, brittle plaster, or trim nailed into fragile drywall can increase the charge to $100-$200. Disposal is sometimes included, but a contractor may add $25-$75 if debris must be hauled away separately.
Painting unfinished casing often costs $1-$5 per linear foot, depending on whether the quote includes sanding, primer, one or two finish coats, and site protection. Staining can cost more than basic painting because the wood must be stain-grade and the finish needs more careful color matching. Pre-finished trim may reduce on-site painting labor but can cost more to purchase.
Other possible charges include delivery fees of $25-$100, a small-job minimum of $100-$250, or patching and repainting the surrounding wall at $50-$250 per opening. These are not automatic charges; they depend on the project and should appear as separate line items in the estimate.
Before approving removal, check whether existing trim can be reused or painted in place. If the casing is damaged or the new profile will not cover the old outline, removal and wall touch-up may be necessary.
How to control the casing budget without cutting corners
Keep the scope consistent across quotes. Specify the number of doors and windows, whether casing is needed on one or both sides, approximate profile width, material, and finish. Ask for a per-opening or per-linear-foot breakdown and confirm whether removal, delivery, caulk, paint, and cleanup are included.
Choosing a standard paint-grade profile from local stock can avoid custom milling and reduce lead time. A simpler 2¼-inch or 3¼-inch design may cost less than a layered profile while still covering the joint cleanly. If the existing casing is sound and matches the room, refinishing it can cost less than replacing it, particularly when removal would damage the wall.
Combining several openings into one appointment can spread setup costs across more trim. Homeowners can also clear furniture, remove curtains, and provide clear access before the crew arrives. Such preparation should not include cutting, fastening, or handling tools unless the contractor has agreed to it, since inaccurate cuts can waste material or create rework.
The most reliable savings come from reducing avoidable labor and choosing standard materials, not from underestimating finish work. A low quote may exclude painting, wall repair, or one side of the opening, so compare complete totals before deciding.
