Our Services

Complete solutions for foundations, crawlspaces, and basement protection in Tigard and nearby areas.

Foundation Waterproofing

Tigard's high water table and frequent rain create persistent moisture against foundation walls. We install interior drainage systems (WaterGuard®, DryTrak®) that capture water before it enters. Perimeter drains and sump pumps work 24/7 to keep basements dry and protect your crawlspace in neighborhoods like Southview and Bull Mountain.

Crawlspace Vapor Barrier Installation

Older Tigard homes from the 1960s–1970s often have bare dirt crawlspaces that invite mold, pests, and poor air quality. We install 120-mil thick vapor barriers sealed on floors and walls. Combined with drainage matting and sump pumps, your crawlspace stays dry and your home's indoor air improves dramatically.

Crawlspace Cleanup & Remediation

Neglected crawlspaces in Tigard homes often accumulate mold, debris, and pest damage. We remove old insulation, clear standing water, clean affected surfaces, and replace damaged wood. This stops mold spores from entering living areas and prepares the space for waterproofing. Fresh, clean crawlspaces mean healthier homes for families throughout the area.

Why This Matters Now

Tigard's climate creates unique challenges. Acting early prevents expensive structural damage.

High Moisture Year-Round

Tigard averages 41 inches of rain annually. Without proper drainage and sealing, foundations and crawlspaces stay constantly wet. Mold and wood rot follow quickly, leading to thousands in repairs.

Old Homes, Aging Foundations

Neighborhoods like Southview and Cook Park have many homes from the 1960s–1970s. These lack modern waterproofing. Cracks, bowing walls, and settling are common—early fixes stop damage.

Seismic Risk & Code Updates

Tigard sits in an active seismic zone. Older homes built before 1990s code updates may lack proper foundation anchoring. Waterproofing goes hand-in-hand with structural protection.

Waterproofing isn't just about keeping water out. It's about preserving your home's value, protecting your family's health (fewer mold allergies), and avoiding emergency repairs when seasonal rains peak.
