Other risks in Washington

Atmospheric rivers and flooding

Heavy, prolonged rain floods rivers and saturates soil, especially in western Washington.

Freezes and wildfire smoke

Cold snaps freeze pipes, and summer wildfires bring smoke into homes.

Earthquake risk

Western Washington sits in an active seismic zone, and earthquakes can break pipes and water heaters. Strapping water heaters and using flexible supply lines reduces the risk.

Signs you need mold removal

  • Visible spots or fuzzy growth on walls, ceilings or wood
  • A musty, earthy smell, especially in closets, basements or crawlspaces

Mold Removal questions

How can I prevent mold in a Washington home?

Run bath and kitchen fans, keep gutters clear, maintain a vapor barrier in the crawlspace, and fix leaks quickly.

How do I verify a Washington contractor?

Search the Washington Department of Labor and Industries contractor lookup for registration, bond and insurance.

Is bleach enough to kill mold?

Not on porous materials like drywall and wood. Bleach mostly lightens the surface. Porous materials with growth are usually removed, and the moisture source has to be fixed.

Do I need mold testing?

Not always. If mold is visible, the priority is removing it and fixing the moisture. Testing helps when you smell mold but can't find it, or when clearance is required.
