Replacing door casing typically costs $150-$600 per doorway, with an average near $350 for standard interior trim and professional installation. The price depends on casing material, how many sides need replacement, finish work, and whether damaged framing or old trim must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| One interior doorway | $150 | $350 | $600 | Standard casing on both sides |
| Materials per doorway | $25 | $75 | $180 | Primed MDF or wood trim |
| Labor per doorway | $100 | $250 | $450 | Removal, fitting, and installation |
| Paint or stain finish | $30 | $100 | $250 | Depends on prep and number of coats |
Assumptions: standard 30- to 36-inch interior door, ordinary access, and typical U.S. contractor rates.
What Door Casing Replacement Usually Costs
For one standard interior doorway, homeowners commonly pay $150-$600 for new casing, removal of the old trim, installation, and basic finishing. A straightforward job using primed MDF may fall near $200-$350, while hardwood, custom profiles, or extra repair work can push the bill above $500.
Trim is often priced by the linear foot. Basic casing material generally runs $1-$5 per linear foot for MDF or finger-jointed pine, while hardwood or decorative profiles can cost $4-$12 or more per linear foot. A typical door needs roughly 30-40 linear feet to case both sides, depending on dimensions and design.
For a standard doorway, labor and finish work often cost more than the basic trim itself. Exterior doors, oversized openings, and casing on only one side require separate estimates because scope differs.
How Trim, Labor, and Finish Work Shape the Quote
A contractor’s quote may combine material and labor or list each task separately. The table shows common planning ranges for a single interior doorway; local minimum charges and project size can change the total.
| Quote item | Typical range | Pricing basis | What it covers |
|---|---|---|---|
| Casing material | $25-$180 | $1-$12 per linear ft | MDF, pine, hardwood, or profile upgrades |
| Removal and disposal | $25-$100 | Per doorway | Taking off old trim and hauling debris |
| Carpenter labor | $100-$450 | $50-$100 per hour | Measuring, cutting, fitting, and fastening |
| Caulk, paint, or stain | $30-$250 | Per doorway | Filling joints and finishing new casing |
| Wall or jamb repair | $50-$300 | Per affected area | Minor patching or correcting damaged surfaces |
Labor may be estimated as . A small job can still carry a minimum service charge, commonly $100-$200, even when the work takes less than two hours.
Ask whether removal, disposal, caulking, and painting are included before comparing quotes. Some bids cover installation only, leaving finish work as a separate charge.
How Door Size, Wood Species, and Damage Change Pricing
Standard interior doors are often 30-36 inches wide and 80 inches tall. Wider openings or taller doors need more trim and longer cuts; a 42-inch-wide or 96-inch-tall opening can add roughly $25-$100 in material and labor, especially when the profile requires careful matching.
Material choice also matters. Primed MDF is typically the least expensive option for dry interior rooms, while pine costs more and solid oak or maple can cost substantially more. Hardwood may be selected to match existing stained trim, but color and grain matching can increase finishing time.
Damage behind the casing is another variable. If removal exposes a cracked jamb, loose drywall, or moisture damage, repairs may add $50-$300 or more. Rot or structural damage around an exterior door is a different repair scope and should be priced separately.
Profile matching and hidden wall damage can matter more than the doorway’s basic width. Provide photos and measurements when requesting a quote, and identify whether both sides of the door need new trim.
When Can Repairing Casing Cost Less Than Replacement?
Small dents, separated joints, and chipped paint may be repairable for $75-$250 per doorway, including patching and touch-up work. Repair is usually less costly when the damage is limited to one short area and the casing profile remains available for a close match.
Replacement often makes more sense when several pieces are split, the trim is swollen from moisture, or prior layers of paint make a clean repair difficult. Replacing one side only may cost $100-$350, but a mismatch in age, profile, or finish can make replacing both sides the more consistent choice.
Compare the repair price with a full replacement quote when damage affects more than one casing leg. A low repair bid may not include repainting the entire doorway or blending the finish into nearby trim.
What Labor Time and Regional Rates Add to the Bill
A carpenter typically spends about 2-4 hours removing and installing standard casing on one doorway when the jamb and walls are in good condition. Painting or staining may require additional visits or drying time, even if hands-on labor is limited. Multiple doorways in one visit can reduce the per-door labor charge.
Rates vary by location. In high-cost metropolitan markets, labor and minimum charges may run 15%-30% above a national midrange estimate. Smaller towns and rural areas may be 5%-20% below it, although travel fees or limited contractor availability can offset savings.
For a single doorway, the contractor’s minimum charge can outweigh modest differences in material price. Scheduling several doors together can make setup and travel costs more economical per opening.
Three Door Casing Quotes for Common Projects
A basic quote might cover one 32-inch interior doorway with primed MDF, removal, and installation. At about 34 linear feet of material and 2.5 labor hours, the total could land around $220-$350 before extensive wall repairs.
A midrange project could replace both sides of a 36-inch doorway with pine casing, add caulk and paint, and include minor drywall patching. With roughly 36 linear feet, 3-4 labor hours, and finish supplies, a realistic total is $350-$600.
A higher-cost job might use oak casing to match nearby stained trim, require careful profile matching, and include removal and stain finishing. For about 40 linear feet and 4-6 labor hours, the estimate may reach $650-$1,000, depending on wood grade and finish labor.
These examples assume ordinary access and no major jamb or framing repair. Quotes should state the material, linear footage, labor, finish scope, and any exclusions so the totals can be compared fairly.
How to Lower the Door Casing Replacement Price
Keep the existing profile when it is readily available, and choose primed MDF or paint-grade pine if a stained hardwood match is not necessary. Confirm whether casing on one side is sufficient, but account for appearance and trim condition on the other side before limiting the scope.
Remove furniture and clear the work area before the carpenter arrives. Ask for separate prices for removal, installation, and painting, then compare at least two itemized quotes. If several doors need work, request one bundled price rather than paying separate minimum charges.
Controlling the material, finish, and number of doorways is usually more effective than choosing trim by price alone. Avoid paying for full replacement when a small repair will restore sound casing, but do not conceal moisture damage behind new trim.
