Drywall & Surface Repair – Lafayette, CA

Lafayette sits in the East Bay hills with a mix of older preserved plaster homes, mid-century custom drywall, and newer construction on cut-and-fill lots. The canopy and hillside setting are part of what makes Lafayette distinctive — they're also part of why walls here crack and shift more than flatland homes.

Hillside cut-and-fill lots settle unevenly over decades, and that shows up as diagonal cracks running from door and window corners, stair-step cracks at ceiling-wall junctions, and failed tape on long wall runs. Older homes — many from the 1950s and 60s — were built with plaster-and-lath, and plaster cracks along stress lines rather than at seams. Newer custom homes on the hills use standard drywall with smooth or light-orange-peel finishes, and those develop seam cracks and nail pops as the structure moves. Downtown condo buildings near Mt. Diablo Blvd show the usual multi-unit wear: doorknob impacts, picture-rail holes, and scuffed corners in hallways and entry areas.

We handle the full range for both plaster and drywall construction. For drywall: nail pops, picture holes, doorknob punch-throughs, water-damage cutouts, failed seam tape, cracked corner bead, and full sheet replacement. For original plaster walls we use PlasterWeld bonding agent, plaster washers to re-anchor loose sections, and a two-coat finish-plaster method to match the surrounding surface. Setting compounds are USG Sheetrock 90 and 45 for structural work, USG Plus 3 lightweight topping for finish coats. Zinsser BIN shellac primer goes on every stained or water-affected surface before paint.

Older Lafayette homes with preserved plaster have a hand-applied finish that varies subtly across a room — matching it takes plaster technique, not drywall compound. Newer custom homes more often have smooth or light-orange-peel surfaces. We spray test patches on scrap board and adjust before touching the wall. Light orange-peel in a high-ceiling room catches raking light at different angles throughout the day, so we check the patch from multiple positions before signing off.

Hillside homes get roof leaks and gutter overflows that track inside along rafters before showing up as a ceiling stain. We confirm the leak source is corrected before cutting. Once dry, we remove all soft material back to solid substrate, install backing, tape, set with USG 90, finish with Plus 3, sand, and apply Zinsser BIN before priming. Plaster walls that absorbed moisture need extra dry time — we check moisture readings before closing up.

Surface type is the biggest variable: plaster repairs require different materials and take more time than standard drywall patches. Settling cracks that run diagonally need to be V-grouted and stabilized before taping — a straight seam crack costs less to repair. High ceilings and hillside access add setup time.
