Installing an interior door costs $802 on average, and most homeowners pay between $363 and $1,241 per door.1,2 Labor is a small part of that. The door you pick, slab or prehung, hollow or solid, sets most of the price.2,3 Prices below are national averages* for 2026.
*National averages, not local quotes. Your price depends on door type and size, whether the frame needs work, trim, hardware and local labor rates.

Slab or prehung

| Slab door | $300 – $500 | Angi |
| Prehung door | $450 – $1,000 | Angi |
| Prehung door, all-in estimate | $529 – $804 | Homewyse |
A slab is just the door. A prehung door comes already hung in its frame, which makes fitting easier in a new opening and costs more. Homewyse prices a basic hollow-core prehung door at $187 to $286 retail, with the rest being labor, supplies and equipment.2,4

DIY or hire
Swapping a slab door or a prehung door into an existing opening is a manageable DIY job if you own a level, shims and a drill. Fixr puts the labor for a standard door at 1 to 3 hours, so DIY saves roughly $44 to $249.3 Hire a pro if the opening needs widening or reframing. Home Depot’s prehung door category shows standard sizes so you can match the opening before you buy.
