What We Do

What Our Basement Waterproofing Service Actually Covers

Every Sumner, IL 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 Sumner, IL 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

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 Sumner, IL basement leak sources, and it's often the cheapest fix on the list.
