How much does door installation cost?
Basic door installation often costs $338 - $1,488 for many interior or exterior doors. Entry doors, frames, sidelites, smart locks, storm doors, custom sizes, and finish work can push projects to $2,000 - $6,000+.
A door quote should clarify whether it is for a slab, pre-hung unit, frame, threshold, weatherstripping, trim, lockset, painting/staining, disposal, and any wall or rot repair.

Before ordering a door
- Measure the door slab and the rough/opening size, but let the installer confirm before ordering.
- Ask whether the quote is for a slab only or a full pre-hung unit with frame and threshold.
- Confirm who handles locksets, smart locks, painting, staining, trim, and disposal.
- Check whether the door leaks air, rubs, or has soft wood around the sill.
Unlock the hiring checklist
Use this before you call a door installation, so you know what to ask and what to avoid.
Call a pro when…
- The frame is rotted, out of square, or leaking
- The door is exterior, security-related, or needs weather sealing
- A new size, sidelite, patio opening, or structural change is involved
- Locks, deadbolts, or smart hardware need clean alignment
- You need the door finished, trimmed, and sealed correctly
Repair or replace?
Repair can work for hinge adjustment, weatherstripping, latch alignment, minor trim issues, or a good slab in a good frame. Replace the door or pre-hung unit when the slab is warped, the frame is rotten, the threshold leaks, security is poor, or energy loss is persistent.
Need a cleaner scope before you call around?
Use the doors checklist to compare the same work, questions, cleanup, and warranty before choosing a local company.
Related questions
Is it cheaper to install a slab door or a pre-hung door?
A slab can be cheaper if the existing frame is square and in good condition. A pre-hung door costs more but is often better when the frame, threshold, or alignment is bad.
Does door installation include painting?
Not always. Many quotes install the door only. Ask whether primer, paint, stain, trim caulk, and touch-ups are included.
Can a handyman install a door?
For simple interior doors, yes. For exterior doors, leaks, rot, security hardware, or frame changes, use a contractor comfortable with flashing, weather sealing, and finish carpentry.
