Replacing door trim is a common task for construction professionals, with costs ranging from $140 to $390 per interior opening. Factors such as material choice, profile complexity, and regional labor rates significantly impact the final cost. This guide provides a detailed breakdown of costs and offers strategies to optimize your budget.
Across the United States, professionals typically charge $140–$390 per standard interior door for trim replacement. Exterior doors may cost $250–$600 due to additional requirements like weather-resistant finishes. Access localized cost data to ensure accurate estimates for your region.
• Linear footage of trim: Taller doors and wider headers require more material and labor.
• Profile complexity: Craftsman and two-piece assemblies take longer to install.
• Material type: MDF is budget-friendly, while hardwoods like oak are premium.
• Paint vs. stain: Stain-grade lumber requires more preparation.
• Existing conditions: Issues like lead paint or damaged jambs increase labor hours.
• Project size: Larger projects allow for cost efficiencies.
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: $155–$238 per door
While DIY can be cost-effective for simple projects, professional installation ensures quality, especially for complex profiles. Consider tool rental costs and potential rework when deciding.
