Crawl Space Encapsulation in Bremerton
Crawl space encapsulation involves sealing the crawl space entirely with heavy-duty vapor barriers and often includes a dehumidifier. This not only waterproofs the walls but also controls humidity, preventing mold growth and wood rot in the crawl space. Washington has two very different climates, with long, wet and mild seasons in the west and hot, dry summers and cold winters in the east. An encapsulated crawl space can noticeably improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use tough, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.

Waterproofing for Older Homes in Bremerton, WA
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Housing in Washington ranges from early 1900s homes to new construction, with plumbing materials that change a lot from one decade to the next. 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.
Interior Walls Waterproofing in Bremerton, WA
Interior walls waterproofing focuses on managing water that has already penetrated the foundation walls. This typically involves installing an interior drainage system, often called a French drain, along the perimeter of the basement floor. Water is collected and channeled to a sump pump, which then sends it safely away from the foundation. While not preventing water from entering the wall, it stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and is suitable where exterior access is limited.
Waterproofing Costs vs. Repeat Water Damage in Bremerton, WA
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.
Shower Pan Leak Repair and Waterproofing in Bremerton, WA
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 proves the pan is watertight before tile.
Crawl Space Vapor Barriers in Bremerton
Many homes in Bremerton 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 stops 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.
Commercial Wall Waterproofing in Bremerton
Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure. We waterproof commercial showers, mop sink walls and restroom wet walls with durable membranes. Work can be scheduled after hours to reduce downtime. We also repair the plumbing behind those walls when leaks are discovered.
