Interior door installation covers hanging pre-hung doors (frame included) or fitting slab doors into existing frames. Pre-hung doors are the faster option and include a new jamb, hinges, and strike plate. Slab doors are more economical if the existing frame is in good condition — we mortise the hinges, drill the lockset bore, and hang the door with proper reveals. We install bedroom, bathroom, closet, pocket, and barn-style sliding doors. All installations include hardware (handle set and hinges), trim (casing), and adjustment for smooth latching and swing.

South San Francisco is located in San Mateo County (Peninsula). Biotech hub with older working-class neighborhoods and newer developments near the hill. The local utility provider is PG&E.

Project Timeline

Old Door Removal

10-15 min

Remove the existing door from its hinges, pull the hinge pins, and remove the old casing trim. For pre-hung installations, remove the old frame as well.

Frame Preparation

15-30 min

Check the rough opening for plumb and square. For pre-hung doors, position the frame and shim for plumb. For slab doors, mortise the hinge locations on the jamb and door edge.

Door Hanging & Hardware

30-45 min

Secure the frame (pre-hung) or hang the slab door on hinges. Install the handle set and strike plate. Adjust the hinges so the door swings freely and latches smoothly with even reveals.

Trim & Finishing

20-30 min

Nail on the door casing trim, fill nail holes with wood filler, and caulk the trim-to-wall joint if desired. The door is ready for painting or staining.

Interior Door Installation in South San Francisco — FAQ

How much does interior door installation cost?+

A pre-hung hollow-core door runs $200-$400 installed in the Sacramento area. Solid-core doors cost $300-$600. Slab-only installation (using the existing frame) is $150-$300 per door.

Pre-hung vs. slab door — which should I choose?+

Pre-hung doors include a new frame and are best when the existing frame is damaged or you want a fresh, perfectly aligned installation. Slab doors save money if the frame is square and in good condition.

How long does interior door installation take?+

A single pre-hung door takes 1.5-2.5 hours. A slab door in an existing frame takes 1-2 hours. Multiple doors in the same visit are more efficient — expect 1-1.5 hours each after the first.

Do you install barn doors or pocket doors?+

Yes. Barn door installation takes 1.5-2 hours and requires a structural header or blocking above the opening. Pocket doors are more complex (3-5 hours) as they require modifying the wall framing.
