What We Do

Comprehensive Basement Waterproofing Solutions in Allenton, WI

Every Allenton, 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 Allenton, 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 Allenton, 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 Allenton, WI basement leak sources, and it's often the cheapest fix on the list.
