Labor to trim a door usually runs $100-$250 for a standard interior doorway, with a typical charge around $150-$175 when casing is installed on both sides. The final price depends on the number of doors, casing style, wall condition, removal work, and local carpenter rates; materials are usually extra.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor per standard door | $75 | $150 | $250 | Install casing on both sides, straightforward opening |
| Labor per side | $40 | $75 | $125 | Useful for one-sided trim work |
| Labor for 5 doors | $350 | $700 | $1,250 | Discounts may apply to grouped work |
| Labor with old trim removal | $125 | $225 | $400 | Per door; patching and disposal affect price |
What labor costs to trim one standard door
A carpenter typically charges $100-$250 in labor per interior door to measure, cut, fit, and fasten casing on both sides. A simple opening with square corners and standard 2¼- to 3½-inch casing tends toward the lower end. Wider or decorative profiles, uneven walls, and detailed miters can move the quote higher.
Labor-only pricing assumes the homeowner supplies casing and nails, and that the opening is ready for trim. A small-job minimum may apply even when only one door is involved. Some contractors quote by the opening, while others price each side separately, so estimates should state whether both sides are included.
Assumptions: One standard 30- to 36-inch interior door, two trim sides, normal access, and no painting or major wall repairs.
Where casing labor hours and materials enter the quote
Labor is generally the largest part of a basic trim installation, but the quote may also include measuring, cutting, fastening, and cleanup. The table shows common costs for one standard door; material quality and local pricing change the totals.
| Quote item | Typical price | What it covers | Common cost driver |
|---|---|---|---|
| Carpenter labor | $100-$250 per door | Cutting, fitting, fastening | Profile detail and wall condition |
| Primed MDF casing | $1-$4 per linear ft | Basic paint-grade trim | Width and profile |
| Solid wood casing | $3-$10 per linear ft | Pine, poplar, or hardwood | Species and finish grade |
| Removal and disposal | $25-$100 per door | Taking off existing casing | Adhesive, nails, and damage risk |
| Caulk and nail-hole prep | $20-$60 per door | Basic fill and caulk | Finish expectations |
A typical door uses roughly 28-34 linear feet of casing for both sides, depending on the opening and head trim. Confirm whether material, removal, caulking, and painting are included before comparing labor quotes.
How door width and wall depth change labor
Door size and opening condition affect cutting time more than the door slab itself. A 30-inch opening is usually simpler than a 48-inch double door, which needs longer head pieces and more careful alignment. Extra-wide or arched openings may require specialty cuts and can add $50-$200 or more in labor.
Wall depth matters when jambs sit flush with drywall. If the jamb is recessed or extends beyond the wall, the carpenter may need jamb extensions or custom returns. A wall variation greater than about ¼ inch across the opening can require scribing, shimming, or additional fitting, adding 30-90 minutes.
At $50-$100 per carpenter hour, a 2-3 hour standard installation represents roughly $100-$300 before any minimum charge.
Double doors, uneven openings, and casing wider than 4 inches deserve a site-specific estimate.
Can trimming several doors lower the labor bill
Often, yes. A carpenter already on site can measure and cut several openings in sequence, reducing setup and travel time per door. For three or more standard doors, labor may fall to about $80-$200 each, provided the openings are similar and no door needs extensive repair.
For example, three straightforward doors at $125-$175 each may total $375-$525 in labor. Five doors with removal and minor fitting could run $700-$1,250. Ask the contractor to show both the per-door rate and any project minimum, rather than assuming a volume discount is automatic.
Grouping doors in one visit is usually more economical than booking separate small jobs.
How regional carpenter rates shift door-trim prices
Labor rates vary with local wages, housing demand, and contractor availability. In lower-cost rural markets, a standard door may be closer to $75-$175 in labor. Many suburban and mid-sized city quotes fall around $100-$250, while high-cost metro areas can reach $150-$350 for detailed work.
Those ranges are not fixed regional tariffs. Travel charges, parking, minimum service fees, and limited access can affect a one-door project, especially in dense urban areas. Compare at least two local written estimates with the same scope and trim profile.
When old casing removal or paint adds charges
Removing existing casing can add $25-$100 per opening, and more if it is glued, layered, or likely to damage drywall. Patching damaged plaster or drywall may add $50-$200, depending on the area and whether a separate finisher is needed. Disposal fees are often modest but should be listed when old trim is hauled away.
Painting is commonly priced separately. Basic paint labor may add $50-$150 per door, while custom stain or multi-coat finishing can cost more. Allow extra time for drying; some contractors install prefinished casing to reduce on-site finishing work.
Ask whether the quote includes removal, surface preparation, caulk, nail filling, and final paint.
Repairing existing trim versus replacing the casing
Small gaps, loose sections, or a few damaged corners may be repairable for about $50-$150 in labor per door. Full replacement is more practical when casing is split, swollen, badly painted, or mismatched. Replacement labor is often $100-$250 per door, plus materials, removal, and possible wall repairs.
Replacing only one side can cost less, but mismatched profiles or faded finishes may make the repair noticeable. If the trim is sound, a carpenter may be able to reattach and caulk it instead of rebuilding the entire surround. Have the estimate separate repair labor from full replacement so the price difference is clear.
How to reduce labor without sacrificing a clean fit
Choose a standard casing profile and keep the same trim design across multiple doors. Clear furniture and stored items from the work area, and verify that the contractor is not charging to move belongings. Supplying material can help, but only if the quantity, profile, and quality match the carpenter’s specifications.
Get written quotes that identify labor per door, both sides or one side, removal, prep, and finish work. Avoid cutting costs by skipping accurate measuring or fastening: poorly fitted casing can leave gaps that require recutting or later repair. The biggest controllable savings usually come from bundling doors and limiting unnecessary removal or upgrades.
