ServiCover📌 Key Takeaway: Interior door installation averages $226-$824 per door. Solid-core doors cost more than hollow-core but block noise better, and specialty doors like pocket doors involve wall work that raises the price.
Hollow Core vs. Solid Core
| Factor | Hollow Core | Solid Core |
|---|---|---|
| Price | Lowest | Higher |
| Sound blocking | Minimal | Much better |
| Feel | Lightweight | Heavy, substantial |
| Best for | Closets, budget projects | Bedrooms, offices, bathrooms |
Specialty Interior Doors
- Barn doors — surface-mounted sliders; need clear wall space beside the opening
- Pocket doors — slide into the wall; require opening the wall and clearing it of wiring and plumbing
- Bifold doors — common for closets; lower cost
- French doors — glass panels for offices and dining rooms
Saving on Multiple Doors
Replacing several doors at once usually lowers the per-door labor cost. Many homeowners swap all interior doors in one project to get a consistent style — and often pair it with new hardware and trim.
For small jobs like fixing a sticking door or swapping hardware, a handyman is often the most affordable option.
Frequently Asked Questions
Can I replace just the door and keep the frame?
Yes — slab replacements work well when frames are in good shape, but matching hinge locations takes careful fitting.
How long does an interior door install take?
A prehung interior door commonly takes an hour or two; slab fitting and specialty doors take longer.
