Walls Waterproofing in Missoula, MT

Reliable Walls Waterproofing Services in Missoula, MT

Plumbing Leak Behind Walls in Missoula

A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We find the leak with moisture meters, thermal imaging and pressure tests. The damaged section of pipe or valve is replaced, and wet drywall is cut out and dried. Once the cavity is dry, we restore the wall and seal any wet-area surfaces.

Crawl Space Vapor Barriers in Missoula

Many homes in Missoula have crawl spaces, which are highly susceptible 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 affordable way to control humidity and prevent wood rot.

Exterior Foundation Waterproofing in Missoula

Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most effective method for preventing water from entering the basement or crawl space. We use high-quality asphalt-modified polyurethane membranes or polymer-based coatings that resist hydrostatic pressure and soil movement. Some areas have expansive clay that swells when wet, which can shift foundations and stress buried pipes. Proper drainage solutions, such as French drains, are also added to divert water away.

Below-Grade and Basement Wall Waterproofing in Missoula

Older homes in Montana often have galvanized supply lines and cast iron drains that have corroded or narrowed with age. Wherever a home has a basement or below-grade walls, heavy rain and snowmelt can push water through foundation walls and cracks. We seal cracks with injection products, apply interior or exterior waterproofing and install drainage where needed. A sump pump may be added if groundwater builds up.

Basement Wall Sealing in Missoula, MT

Basement wall sealing is a key part of walls waterproofing. Rapid temperature swings, including sudden warm winds in winter, can stress pipes and fittings that go from frozen to thawed quickly. We apply high-quality sealants to porous concrete and masonry walls to prevent moisture from wicking through and causing dampness, mold, or musty odors. This service can be performed alone or as part of a larger waterproofing system, offering a drier, healthier environment in your Missoula, MT basement.

Commercial Wall Waterproofing in Missoula

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 limit downtime. We also repair the plumbing behind those walls when leaks are discovered.

Shower Pan Leak Repair and Waterproofing in Missoula, MT

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 confirm 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.
