Licensed Exterior Waterproofing service in Nashotah, WI - SGP Waterproofing
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 Nashotah, 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

Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.

4

Dimpled Membrane & Footing Drain Systems

Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.

What We Do

What Our Exterior Waterproofing Service Actually Covers

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

Exterior

Foundation Excavation & Membrane Installation

This is the most comprehensive Nashotah, WI waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.

Exterior

Footing Drain (French Drain) Installation

A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.

Exterior

Exterior Grading Correction

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

Exterior

Window Well Excavation & Drainage

Window wells collecting water get excavated, fitted with a gravel bed, and tied into the exterior drain system so they stop acting as a funnel toward the foundation.

Exterior

Downspout & Gutter Extension

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

FAQ

What Nashotah, 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?

We measure your specific foundation during the on-site inspection rather than assuming a standard 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 Nashotah, 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.
