Basement & Crawl Space Waterproofing Services Portland OR

Protect your home from water damage with professional waterproofing services from Foundations First Northwest. We provide basement waterproofing, crawl space waterproofing, and drainage solutions throughout the Portland Metro, Oregon Coast & Surrounding Areas. Our goal is simple: keep water out, reduce moisture, and help protect your foundation and indoor air quality.

Pacific Northwest weather brings heavy rain, high groundwater, and seasonal moisture swings. Without the right waterproofing plan, basements and crawl spaces can stay damp for long periods, leading to damage and ongoing odor and mold conditions. We build waterproofing systems that match local conditions and the way water moves around your home.

1. Basement Water Problems:
   Water intrusion in basements creates serious structural and health concerns. Leaking basement walls, water seeping through foundation cracks, and standing water after heavy rains indicate your basement needs professional waterproofing. Damp basement conditions promote mold growth, damage stored items, and compromise indoor air quality.
2. Crawl Space Moisture Issues:
   Crawl spaces naturally accumulate moisture from ground water and humid air. Without proper crawl space waterproofing, this moisture damages floor joists, creates musty odors throughout your home, and attracts pests. Wet crawl spaces reduce energy efficiency and threaten structural integrity.
3. Foundation Water Damage:
   Water around your foundation causes settlement, cracks, and structural deterioration. Foundation waterproofing prevents these costly problems by directing water away from your home’s base. Proper waterproofing protects your investment and maintains property value.

• Basement Waterproofing

  We use basement waterproofing methods that focus on controlling water at the entry points and guiding it to a safe discharge location. This can include interior drainage, sealing, and moisture control steps that help keep basements usable and drier year-round.

• Crawl Space Waterproofing
  Crawl space waterproofing starts with identifying where moisture is coming from and then sealing and controlling it. Depending on the conditions, this may include encapsulation components that reduce ground moisture and help protect wood framing from long-term exposure.
• Sump Pump Systems

  Sump pumps actively remove collected water from basements and crawl spaces. When appropriate, we install reliable systems that can include backup protection to help during storms and outages.

• Drainage Systems

  Waterproofing works best when drainage is handled correctly. We install systems that move water away from the foundation to reduce pooling and pressure against foundation walls.

• Vapor Barriers

  Vapor barriers help block moisture from rising into the crawl space from the soil. Proper installation and sealing are what make the barrier effective and durable long-term.

• Foundation Crack Repair

  Cracks are common entry points for water. We repair and seal cracks using professional methods designed to reduce water intrusion and help protect the foundation.
