What We Do

The Full Scope of Our Green Bay, WI Basement Waterproofing Work

Every Green Bay, WI 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 Green Bay, WI 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

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?

Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.

Will you cut into my basement floor?

We keep the cut as narrow as possible and clean up debris before leaving the site.

How long does basement waterproofing take?

Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.

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.

Is basement waterproofing covered by insurance?

Coverage depends on your policy and the cause of the water intrusion — we can document conditions for a claim, but approval is up to your insurer.

Do you offer a warranty on basement waterproofing work?

Yes, every interior drain tile and sump installation comes with a written warranty, explained in full before you approve the quote.
