Why Choose Us

Four Reasons Our Basement Waterproofing Clients Don't Call Anyone Else

Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.

What We Do

The Full Scope of Our Waukesha, WI 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

The core fix for most Waukesha, 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

Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.

Basement

Wall Crack & Cove Joint Sealing

The cove joint where the floor meets the foundation wall is one of the most common Waukesha, WI 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 Waukesha, WI basement leak sources, and it's often the cheapest fix on the list.
