At some point every homeowner asks the same question—how much to replace door trim and refresh the look of an entryway? While a single casing upgrade sounds simple, the final cost can swing widely depending on material, labor, and finish decisions. This in-depth guide breaks down real-world numbers, explains cost drivers, and shows how CountBricks’ AI-powered estimating platform keeps budgets accurate from takeoff to invoice.
Across the United States, homeowners typically pay $140–$390 per standard interior door to remove old casing, install new trim, fill nail holes, caulk, and apply a fresh coat of paint. Exterior doors trend higher, often $250–$600 because of thicker profiles, weather-resistant finishes, and ladder work. With CountBricks.com/services you receive localized cost data in seconds, so you know the Akron, Ohio price isn’t the same as Phoenix, Arizona.
• Linear footage of trim: Taller doors and wider headers mean more material and labor
• Profile complexity: Craftsman, back-banded, and two-piece assemblies take longer to cut and cope
• Material type: MDF is budget-friendly, finger-joint pine mid-range, and hardwoods like poplar or oak command premium prices
• Paint vs. stain: Stain-grade lumber must be selected carefully and sanded between coats, adding time
• Existing conditions: Lead paint removal, out-of-square plaster walls, or damaged jambs can raise labor hours
• Project size: Replacing trim on 10 doors allows installers to batch cuts and reduce per-unit cost
1. Removal and disposal of old casing: $15–$25
2. New 2 3/4" finger-joint pine trim (15 linear feet): $22–$30
3. Fasteners, caulk, filler: $5–$8
4. Labor to cut, install, and prep: $70–$120
5. Prime and paint two coats: $28–$55
Total estimated with CountBricks: $155–$238 per door*

Replacing one or two simple doors could be a rewarding weekend project if you already own a miter saw, compressor, and nailer. However, CountBricks data shows that DIY savings shrink when you factor in tool rental ($45/day), leftover paint, and potential rework if miters don’t align. For stain-grade oak or ornate profiles, professional installers consistently deliver cleaner joints and tighter shadow lines, protecting the resale value of your home.

Does replacing door trim require building permits?
Generally no, but historical districts may need design approval. CountBricks flags jurisdiction requirements during estimate creation.
How long does it take to replace trim on one door?
A seasoned carpenter averages 45–60 minutes for removal and new install, plus drying time between paint coats.
Can I reuse existing trim?
In theory yes, but MDF chips easily on demo and nail holes rarely align. New casing usually delivers a better finish for minimal added cost.
