We excavate only where necessary and restore landscaping as part of the scope.
We excavate only where necessary and restore landscaping as part of the scope.
A lot of Oconomowoc, WI exterior waterproofing failures trace back to a footing drain that was installed without proper slope, which means it never actually moved water the way it was supposed to. We verify slope during installation, not just at design.
Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.
Weather-dependent scheduling means we plan exterior jobs around Oconomowoc, WI's rainy season windows when possible.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.
Every Oconomowoc, WI Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.
A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
We also inspect and reseal the window frame itself while the well is open.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.
We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.
