Why Choose Us

What Sets Our Exterior Waterproofing Team Apart in Clarkston, WA

A lot of Clarkston, WA 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.

What We Do

What Our Exterior Waterproofing Service Actually Covers

Every Clarkston, WA 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

We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.

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.

Excavation, Membrane & Backfill

Customer Reviews

Real Exterior Waterproofing Reviews From Clarkston, WA Property Owners

Top rated local Exterior Waterproofing specialists in Clarkston, WA
★★★★★

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

— Clarkston Homeowner

★★★★★

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

— Clarkston Customer

★★★★★

"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."

— Clarkston Homeowner

★★★★★

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

— Clarkston Customer

FAQ

Frequently Asked Questions 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?

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?

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

How long does exterior waterproofing take?

A typical residential wall section with membrane and footing drain work takes a few days depending on access and weather conditions.
