What We Do

The Full Scope of Our North Tonawanda, NY 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

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 North Tonawanda, NY leak points, and we seal it as part of every interior system.

Basement

Vapor Barrier Wall Membrane

A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.

Basement

Window Well Drainage

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