What We Do

The Full Scope of Our Westport, WA Basement Waterproofing Work

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 Westport, 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

Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.

Basement

Wall Crack & Cove Joint Sealing

The cove joint where the floor meets the foundation wall is one of the most common Westport, WA leak points, and we seal it as part of every interior system.

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

Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.

FAQ

What Westport, WA Customers Ask Us Most 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?▼

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

How long does basement waterproofing take?▼

Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.

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 Westport, WA homeowners have used to support a claim.

Do you offer a warranty on basement waterproofing work?▼

Warranty terms are often transferable if you sell the property later.
