Stucco Waterproofing & Repair in San Francisco
San Francisco’s stucco buildings take a beating that most of California never sees: persistent fog, salt-laden marine air, and wind-driven rain that finds every hairline crack and unsealed penetration in an exterior wall. On older housing stock — much of it stucco over wood framing — small envelope failures can quietly feed water into the structure for years before anyone notices a stain.
Fogg Construction brings 41 years of waterproofing and plaster experience to San Francisco homes and commercial buildings. We diagnose where water is actually getting in, correct the underlying barrier and flashing problems, and finish with stucco work that matches the building’s existing texture — so the repair disappears into the facade.
“Fog, salt air, and wind-driven rain make envelope sealing and flashing detail the difference between a stucco exterior that lasts decades and one that hides rot.”

Window Patching & Restoration
Weathered window perimeters opened, the water barrier reinforced, and stucco blended back seamlessly.
“They were fantastic! The owner came out himself to bid the job, threw in some stucco patchwork that was needed outside of the immediate area to be fixed. The crew was on time, worked quickly, and didn’t leave any debris behind (cleaned up the area perfectly). Not the cheapest, not the most expensive either, but the expertise and skill was evident and I couldn’t be happier. I highly recommend Fogg.”
