Why Choose Us

Four Reasons Our Basement Waterproofing Clients Don't Call Anyone Else

No hourly billing and no change orders once your basement floor is already open.

4

Moisture-Mapping Equipment

Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.

What We Do

What Our Basement Waterproofing Service Actually Covers

Every Westport, WA Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

Basement

Interior Drain Tile

We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.

Basement

Sump Pump & Basin Installation

Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.

Basement

Wall Crack & Cove Joint Sealing

The cove joint where the floor meets the foundation wall is one of the most common Westport, WA leak points, and we seal it as part of every interior system.

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 Westport, WA basement leak sources, and it's often the cheapest fix on the list.
