Common Environmental and Structural Factors

What Causes Basement Leaks and Moisture Issues?

Even the best-built homes in Western Washington are vulnerable to water intrusion. With our region’s heavy rainfall and complex soil conditions, basements often face moisture problems that worsen if left untreated.

  1. Poor exterior grading or landscaping that directs water toward the home – If the soil around your home slopes inward, water naturally flows toward your foundation, pooling along basement walls and eventually finding its way inside.
  2. Clogged or damaged gutters and downspouts – When rainwater isn’t properly directed away from your home, it spills over and soaks the soil at your foundation, contributing to leaks and long-term water damage.
  3. Hydrostatic pressure pushing water through foundation walls – As groundwater builds up in saturated soil, pressure mounts against your basement walls, forcing water through tiny cracks or porous concrete.
  4. Cracks in foundation floors or walls – Even small cracks are entry points for water. During rainy months, these cracks allow water to seep in, creating dampness and eventually leading to mold growth.
  5. Inadequate or failed waterproofing systems in older homes – Many older Washington homes were built without modern drainage or sealing systems, leaving them especially vulnerable to leaks and moisture.
