Moisture-Mapping Equipment

Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.

What We Do

What Our Basement Waterproofing Service Actually Covers

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Basement

Interior Drain Tile

The core fix for most Duluth, WA basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.

Basement

Sump Pump & Basin Installation

Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.

Basement

Wall Crack & Cove Joint Sealing

Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.

Basement

Vapor Barrier Wall Membrane

A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.

Basement

Window Well Drainage

Poor window well drainage is one of the most overlooked Duluth, WA basement leak sources, and it's often the cheapest fix on the list.

FAQ

Frequently Asked Questions About Basement Waterproofing

How much does interior drain tile installation cost?

Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.

Will you cut into my basement floor?

We keep the cut as narrow as possible and clean up debris before leaving the site.

How long does basement waterproofing take?

Most residential interior drain tile and sump installations finish in one to three days depending on basement size.

Do I need a sump pump if I'm just sealing a crack?

If the crack is actively weeping or part of a larger drainage issue, we'll recommend a full system instead of a spot fix.

Is basement waterproofing covered by insurance?

We provide photos and moisture readings that many Duluth, WA homeowners have used to support a claim.

Do you offer a warranty on basement waterproofing work?

Yes, every interior drain tile and sump installation comes with a written warranty, explained in full before you approve the quote.
