Foundation & Waterproofing Services in Forest Grove, OR

Local Waterproofing Expertise

In Forest Grove, winter rains demand a strong foundation—literally. We are your local waterproofing contractor and foundation specialist, serving the historic neighborhoods near Pacific University, the Walker-Naylor district, and throughout Washington County. Rain here isn't occasional; with over 46 inches annually and December humidity reaching 86%, moisture seeps where it shouldn't. Our foundation waterproofing, crawlspace vapor barrier, and window well solutions protect homes built from the 1870s to today. Whether you own a restored Victorian or a modern home near Gales Creek, we keep water out and your foundation dry.

Our Services

Water damage starts small but spreads fast in Forest Grove's wet climate. We solve it before it costs you thousands.

Foundation Waterproofing

Basements and crawlspaces in the Walker-Naylor neighborhood and beyond soak up rain. We seal foundations from the outside in, blocking groundwater before it enters wood framing.


  • Stops wet basements and crawlspace flooding
  • Protects structural integrity on homes 50+ years old
  • Works with historic masonry and modern concrete alike

Crawlspace Vapor Barrier Installation

Crawlspaces breathe moisture into your home. A heavy-duty barrier traps that humidity below, keeping living spaces dry and mold-free year-round in our damp climate.


  • Cuts indoor moisture in half or more
  • Prevents mold on joists and insulation
  • Lowers heating and cooling costs

Window Well Repair & Installation

Basement windows near Gales Creek and downtown often collect rainwater. We install wells, covers, and proper drainage to keep water from pooling and seeping through.


  • Redirects rain away from below-grade windows
  • Adds egress for bedrooms in basements
  • Durable covers keep leaves and debris out

Crawlspace restoration and mold removal in homes throughout Forest Grove

Crawlspace Cleanup & Mold Remediation

Old insulation, standing water, and mold thrive in damp crawlspaces. We remove contamination and restore the space so fresh air can circulate safely.


  • Removes wet debris and damaged insulation
  • Stops mold from spreading into living spaces
  • Prepares crawlspace for vapor barrier or new insulation

Why Local Expertise Matters

Forest Grove isn't like drier parts of Oregon. We know how water behaves here—and how to stop it.

Rain Is Relentless Here

With 46+ inches of rain yearly and December humidity at 86%, water finds every weak spot. Foundations crack. Crawlspaces flood. Wood rots. We've seen it in 1880s Queen Anne homes near Pacific University and in new builds alike.

Historic Homes Need Special Care

The Walker-Naylor and Painter's Woods districts have beautiful brick and stone basements built without vapor barriers. We seal them without damaging original masonry or requiring demolition.

We Know Your Building Codes

Forest Grove design guidelines and Washington County permit rules are strict about historic preservation. Our work respects local standards and passes inspection every time.
