Frequently Asked Questions?
Frequently Asked Questions About Door Replacement
What is the average cost to replace a door?
The cost of replacing a door varies depending on the type of door, materials, and labor costs. On average:
- Interior doors: $150 - $500
- Entry doors: $500 - $2,500
- Patio doors: $700 - $5,000
- Custom or high-end doors: $2,000+
Labor typically adds $100 - $300 per door, but complex installations (like resizing the opening) can increase costs.
Can I just replace a door without replacing the frame?
Yes, you can replace just the door slab (called a slab door replacement) if the existing frame is in good condition. However, if the frame is damaged, warped, or misaligned, it’s recommended to replace the entire door unit (pre-hung door) for a better fit and long-term performance.
Why is replacing a door so expensive?
Several factors contribute to the cost:
- Materials: High-quality doors (solid wood, fiberglass, steel) cost more than basic hollow-core options.
- Labor: Skilled labor is required to ensure a proper fit, insulation, and security.
- Customization: Custom doors, special sizes, or unique finishes increase costs.
- Hardware & Extras: Locks, handles, and trim add to the total price.
Can you just replace an exterior door?
Yes, you can replace an exterior door without changing the frame, but it depends on the condition of the existing frame. If the frame is in good shape, a new door slab can be fitted. If the frame is damaged, it’s better to install a pre-hung door, which includes both the door and frame.
How many hours does it take to replace a door?
- Interior door: 1-3 hours
- Exterior door: 3-6 hours (longer if resizing or replacing the frame)
- Custom or complex doors: May take a full day depending on adjustments needed.
