Exterior Waterproofing in Duluth, WA — Stop Water Before It Reaches the Wall
We excavate only where necessary and restore landscaping as part of the scope.

A lot of Duluth, 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.
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 Duluth, WA's rainy season windows when possible.
Landscaping restoration is included in the scope, not billed as a separate surprise line item.
We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.
Every Duluth, WA 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.
We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
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.
This is often bundled with grading correction since the two issues usually show up together.
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.
We explain what's included in landscaping restoration so there's no confusion after backfill.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.

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.
We discuss landscaping impact during the estimate so there are no surprises.
Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.
Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.
