Understanding Door Trim Replacement Cost for Residential Projects
Door trim replacement is a crucial task for maintaining the aesthetic and functional integrity of a home. Accurate cost forecasting is essential for staying on budget. In 2025, the cost for door trim replacement ranges from $280 to $650 per door, depending on materials and complexity. CountBricks provides AI-driven estimates that integrate real-time material pricing, labor rates, and square-foot calculations for every residential project.
What Drives Door Trim Replacement Cost?
1. Material Choice
- MDF: Affordable and paint-ready, but sensitive to moisture.
- Finger-joint pine: Balances price and durability.
- Solid hardwoods: Oak or maple add luxury and resiliency.
- PVC and composite: Resist rot in humid environments.
2. Profile Complexity
Slim colonial casing is less expensive than stacked Craftsman assemblies. Decorative elements like back-band, rosettes, and plinth blocks add to the cost.
3. Door Count and Opening Size
A standard 80-inch interior slab requires about 17 linear feet of trim. Larger or more complex doors increase both material and labor costs.
4. Site Conditions
Occupied homes, tight spaces, or historical walls can slow installation. CountBricks adjusts labor productivity based on site conditions.
Average Price Ranges in 2025
- Basic MDF casing, painted on-site: $3.25 – $4.75 per linear foot installed.
- Premium hardwood with clear finish: $6.50 – $9.00 per linear foot installed.
- Historic replication or multi-piece stacks: $10.00 – $14.00 per linear foot installed.
