What We Do

The Full Scope of Our Clarkston, WA Basement Waterproofing Work

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Basement

Interior Drain Tile

The core fix for most Clarkston, WA basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.

Basement

Sump Pump & Basin Installation

Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.

Basement

Wall Crack & Cove Joint Sealing

Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.

Basement

Vapor Barrier Wall Membrane

We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.

Basement

Window Well Drainage

Poor window well drainage is one of the most overlooked Clarkston, WA basement leak sources, and it's often the cheapest fix on the list.
