Shower Pan Leak Repair and Waterproofing in San Mateo, CA

A cracked or poorly sloped shower pan often causes wet baseboards and stained ceilings below. We test the pan by plugging the drain and flooding it to verify the leak. Then we rebuild the pan with correct pre-slope, a new liner or bonded membrane and a properly clamped drain. A second flood test confirms the pan is watertight before tile.

Crawl Space Vapor Barriers in San Mateo

Many homes in San Mateo have crawl spaces, which are very prone to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting prevents ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an effective way to control humidity and prevent wood rot.

Waterproofing Costs vs. Repeat Water Damage in San Mateo, CA

Waterproofing a shower or wall costs much less than repeated drywall, cabinet and flooring repairs. Ignoring moisture also invites mold, which can be expensive to remediate. A typical shower wall waterproofing project falls in the low thousands, while exterior block sealing varies with wall size. We give you a written quote so you can compare options side by side.

Waterproofing for Older Homes in San Mateo, CA

Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Older neighborhoods in Northern California include prewar and postwar homes with galvanized supply lines and cast iron or clay sewer pipe that are nearing the end of their life. Many older foundations may lack adequate exterior drainage or proper sealing. We specialize in assessing and upgrading waterproofing systems for these properties, often combining exterior excavation with interior drainage solutions. We respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.
