What We Do

Comprehensive Basement Waterproofing Solutions in Ontario, OR

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 Ontario, OR 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

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

Basement

Vapor Barrier Wall Membrane

We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.

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

Basement Waterproofing Questions We Hear Every Week

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?▼

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 Ontario, OR 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.
