What We Do

The Full Scope of Our Lawrence, NY Basement Waterproofing Work

Every Lawrence, NY 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 Lawrence, NY 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

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.

FAQ

Basement Waterproofing Questions We Hear Every Week

How much does interior drain tile installation cost?▼

Every Lawrence, NY quote is itemized in writing so you can see exactly what drives the total.

Do I need a sump pump if I'm just sealing a crack?▼

If the crack is actively weeping or part of a larger drainage issue, we'll recommend a full system instead of a spot fix.
