Drywall Repair in San Francisco, CA
Wall repairs in San Francisco are rarely just drywall. A large share of the city's houses and flats were built before 1940, which means lath and plaster, often more than a century old, sitting on wood framing that has shifted through every quake since the house went up. Small earthquakes, settling on sandy soil out in the avenues, and the slow drying and swelling of old framing all open cracks over door headers, along ceiling seams and at the corners of windows. Newer condos bring their own set: nail and screw pops in drywall over steel studs, dings from moving furniture up a narrow stair, and the stains a leaky shower upstairs leaves on the ceiling below.
We start by figuring out what the wall actually is. On plaster we re-secure loose sections to the lath, fill and tape the crack with materials that flex a little, and skim the patch so it matches the hard, smooth surface around it. On drywall we cut back to sound board, set new pieces on solid backing, tape and finish in thin coats, and match whatever texture you have — smooth, light orange peel or the occasional knockdown in a remodeled unit. We cover floors and furniture, contain the sanding dust, and leave the room ready for paint or painted, whichever you prefer.

How a drywall repair visit usually goes
Look and Diagnose
We check whether the wall is plaster or drywall, how wide and active the crack is, and whether there's any moisture behind a stain, so we fix the cause and not just the symptom.
Protect and Prepare
Floors and furniture get covered, the work area is contained, and loose material is removed back to a solid edge. On plaster we re-anchor any sections that have pulled away from the lath.
Patch and Finish
We fill, tape and apply thin coats, letting each one set properly — San Francisco's cool, damp air slows drying, especially on the west side, so we don't rush it.
Texture, Prime and Blend
We match the surrounding texture or smooth finish, feather well past the repair, prime with a stain-blocking primer where there was water, and paint if you'd like so the wall looks continuous.
Ceilings under bathrooms are a common source of calls, especially in stacked flats in the Mission, the Western Addition and North Beach where the bathroom of one unit sits directly over the living room of another. A failed tub caulk line or a slow leak from a toilet seal can stain the ceiling below for months before anyone notices. We make sure the source is fixed first, check that the area is dry with a moisture meter, then cut out damaged material and patch it so the stain doesn't come back. On the west side, the fog adds its own wrinkle: cold exterior walls in the Outer Sunset and Outer Richmond can collect condensation and grow surface mildew, which needs to be cleaned and treated before any patch or paint will hold. Out in the Sunset District and Daly City, fog keeps walls near windows damp, so peeling paint and soft drywall are common; in South San Francisco and Oakland it's more often settling cracks in older stucco and plaster.
What shapes the price in San Francisco
The price of a drywall or plaster repair depends mostly on the number and size of the patches, whether the wall is plaster or drywall, and how much finishing it needs to blend in. Plaster that has separated from the lath takes more time than a simple drywall patch, and high Victorian ceilings or stairwells add ladder and scaffold time. Water damage can mean cutting back more than the stain shows, and a hidden leak has to be fixed first. In condo buildings, working hours and elevator reservations affect scheduling. Bundling several repairs into one visit is the most efficient way to get them all done.
Neighbors often ask
Why does the same crack keep coming back over my doorway?
In San Francisco that usually means movement, not bad workmanship. Old framing keeps settling, small quakes shake the house a little, and the seasonal swing between damp fog and dry fall lets wood swell and shrink. We repair those cracks with mesh tape and flexible materials so they stay hidden much longer, but if the crack is wide, angled or growing quickly we'll tell you it's time for a foundation or structural professional to look before we patch it again.
Can you patch plaster without making it look like a drywall patch?
Yes. For most cracks and small holes we stay with plaster-compatible materials, re-secure loose plaster with washers and finish with a skim coat that matches the smooth, hard surface around it. Larger holes may get a piece of drywall shimmed to the plaster thickness and then skimmed over so the transition doesn't show. The goal is a wall that still reads as plaster once it's painted.
How do you handle lead paint on old plaster walls?
Most San Francisco homes were built long before 1978, so we treat old painted surfaces as if they contain lead unless testing says otherwise. For small patches we mist instead of dry sanding, contain the work area and clean up with a HEPA vacuum. Bigger projects that disturb more painted surface fall under federal lead-safe renovation rules, and we'll tell you up front if your project reaches that point.
How long does a plaster or drywall repair take?
Many small repairs can be done in one visit with setting-type compounds, but larger patches and skim coats need time between coats to dry, particularly in a cool, foggy week. Texture and paint add their own drying windows. A bigger repair may need a second short visit so the finish comes out right instead of shrinking or showing through the paint later.
