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

Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.

2

Local Equipment Staging

Weather-dependent scheduling means we plan exterior jobs around Altoona, WI's rainy season windows when possible.

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

Comprehensive Exterior Waterproofing Solutions in Altoona, WI

Every Altoona, 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 Altoona, WI waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.

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 Altoona, 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.

Excavation, Membrane & Backfill

Top rated local Exterior Waterproofing specialists in Altoona, WI
★★★★★

"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."

— Altoona Homeowner

★★★★★

"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."

— Altoona Customer

★★★★★

"Appreciated that they called in utility locates before digging near our gas line."

★★★★★

"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."

FAQ

What Altoona, WI Customers Ask Us Most About Exterior Waterproofing

What's the difference between interior and exterior waterproofing?▼

Interior systems manage water after it enters; exterior systems stop water from reaching the wall in the first place, which is more invasive but often more permanent.

Will excavation damage my landscaping?▼

We discuss landscaping impact during the estimate so there are no surprises.

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?▼

Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.

Can you fix grading without a full exterior membrane project?▼

We'll recommend starting there if the inspection suggests surface water is the primary cause.

How long does exterior waterproofing take?▼

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