Why Crawlspaces Flood in Hillsboro

Hillsboro sits in the Willamette Valley, where seasonal rainfall overwhelms drainage systems. Crawlspaces flood when groundwater rises, gutters dump water next to the foundation, or exterior drain tiles clog with silt. Once water enters, it has nowhere to go. Most crawlspaces do not have sump pumps or drainage, which means water sits until it evaporates or soaks into the soil. During wet months, evaporation is slow, and the space stays damp for weeks. That prolonged moisture destroys insulation, rots wood, and creates ideal conditions for mold.

Immediate Steps After a Crawlspace Floods

Do not enter a flooded crawlspace if electrical wiring or outlets are present. Water and electricity are dangerous. If it's safe to enter, start removing standing water using a sump pump or wet vacuum. Move any stored items off the ground. Do not leave wet insulation in place. It will not dry on its own and will continue feeding mold. Open foundation vents to increase airflow, but do not rely on natural ventilation to dry the space. Active drying equipment is necessary.

Professional Crawlspace Flood Cleanup

We extract standing water using pumps and vacuums, then remove wet insulation and bag it for disposal. Moisture meters tell us how much water soaked into wood framing and subfloor. We place commercial dehumidifiers and air movers to dry structural components to below 15 percent moisture content. If mold is visible, we treat it with antimicrobials. Once the space is dry, we install a vapor barrier and seal foundation vents to prevent future flooding. If drainage issues caused the flood, we recommend exterior solutions like gutter extensions, regrading, or sump pump installation.

Insurance Coverage for Crawlspace Flooding

Flooding from surface water is usually excluded. However, if the water entered due to a plumbing failure, sewer backup, or sudden appliance leak, there may be coverage. We document the source, photograph all damage, and provide a detailed scope. If the cause is covered, we handle the claim and ensure you get the restoration you need.

If your crawlspace flooded, call for emergency extraction. We'll remove the water, dry structural components, and prevent mold before the damage spreads into your living space.
