How It Works
Door replacement costs depend on whether you are replacing interior or exterior doors, the material chosen, and hardware quality. Exterior doors cost significantly more due to weatherproofing, security, and frame requirements.
The Formula
Variables
- Base Door Cost — Door unit price based on type and material: $150-$2,500
- Hardware — Handles, locks, and hinges: basic $50, mid $150, premium $400
- Frame — Exterior door frame and trim cost: ~$150 per door
- Labor — Installation: $175 interior, $350 exterior per door
Worked Example
For 1 exterior fiberglass door with mid-range hardware: Door = $650, Hardware = $150, Frame = $150, Labor = $350. Total = $1,300.

Frequently Asked Questions

An interior door takes 1-2 hours; an exterior door takes 3-5 hours including frame, weatherstripping, and hardware installation.
Should I replace the frame too?
If the existing frame is rotted, warped, or damaged, yes. Pre-hung doors that include the frame are recommended for exterior replacements.
What is the best exterior door material?
Fiberglass is the most popular choice in 2026 due to its durability, energy efficiency, low maintenance, and ability to mimic wood grain.

Generally no permit is needed for a like-for-like replacement. If you are changing the opening size, a permit is typically required.
How much does a front door increase home value?
A new front door typically recoups 90-100% of its cost at resale, making it one of the top home improvements for ROI.
