Plumbing Leak Behind Walls in Sammamish

A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We locate 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 walls.

Basement Wall Sealing in Sammamish, WA

Basement wall sealing is a key part of walls waterproofing. 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. 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 and healthier environment in your Sammamish, WA basement.

Shower Pan Leak Repair and Waterproofing in Sammamish, 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 confirms the pan is watertight before tile.

Drainage System Integration in Sammamish, WA

Lasting walls waterproofing often requires a robust drainage system to divert water away from your foundation. This can include interior perimeter drains that channel water to a sump pump, or exterior French drains that collect surface water. Our team designs and installs custom drainage solutions for Sammamish, WA properties, so water is efficiently managed and moved away from your home's vulnerable areas.

Commercial Wall Waterproofing in Sammamish

Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure.

We also repair the plumbing behind those walls when leaks are found.
