Why Choose Us

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

Exterior work only pays off if the membrane, footing drain, and grading are all addressed together — fixing one without the others often leaves the underlying pressure problem unresolved. We scope the full picture before recommending excavation.

1

Licensed Excavation & Waterproofing Crews

We call in utility locates before any digging starts, standard on every Lancaster, WI exterior job.

2

Local Equipment Staging

Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.

3

Flat-Rate Excavation Pricing

Landscaping restoration is included in the scope, not billed as a separate surprise line item.

4

Dimpled Membrane & Footing Drain Systems

We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.

What We Do

The Full Scope of Our Lancaster, WI Exterior Waterproofing Work

Every Lancaster, WI Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

Exterior

Foundation Excavation & Membrane Installation

We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.

Exterior

Footing Drain (French Drain) Installation

We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.

Exterior

Exterior Grading Correction

Soil that slopes toward the foundation instead of away from it is one of the most common Lancaster, WI water intrusion causes, and it's often the cheapest fix on this list.

Exterior

Window Well Excavation & Drainage

We also inspect and reseal the window frame itself while the well is open.

Exterior

Downspout & Gutter Extension

This is often bundled with grading correction since the two issues usually show up together.

FAQ

What Lancaster, WI Customers Ask Us Most About Exterior Waterproofing

What's the difference between interior and exterior waterproofing?

We'll recommend the right approach based on what the inspection actually finds.

Will excavation damage my landscaping?

Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.

How deep do you need to excavate?

Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.

Is exterior waterproofing more expensive than interior?

We'll walk through both options and their trade-offs so you can make an informed choice.

Can you fix grading without a full exterior membrane project?

Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Lancaster, WI water intrusion issues on their own.

How long does exterior waterproofing take?

Larger projects or difficult access points can extend the timeline, which we'll outline in the written quote.
