What We Do

What Our Basement Waterproofing Service Actually Covers

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

Basement

Interior Drain Tile

The core fix for most Massapequa Park, NY 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

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 Massapequa Park, 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

Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.
