How long does an interior door installation take?

A standard prehung interior door takes 2–3 hours. Slab-only swaps are even faster — about 1 hour each. Most full-house projects (5–10 doors) finish in a single day.

Do I need to remove the old door before you arrive?

No — our crew handles removal and disposal of the old door, frame (if prehung), and trim as part of the install.

Can I add doors to an existing open archway?

Yes! That's our Double Doors (New Opening) service. We frame in the opening if needed, install the doors, and finish with drywall and trim. See our dedicated page for details.

What's the difference between slab and prehung?

A slab is just the door panel — you reuse the existing frame and hinges. A prehung includes a brand new frame, jamb, and trim. Prehung is cleaner and easier; slab is cheaper if your existing frame is in good shape.

Will the new doors match my existing trim?

Yes. We can match your existing trim profile and paint color, or upgrade to a new modern profile. We discuss this during the quote.

Do you sell solid-core doors?

Yes. Solid-core doors block more sound, feel more substantial, and are recommended for bedrooms, offices, and bathrooms. We offer both hollow-core (budget) and solid-core options.
