Mold Inspection in Everett, WA

What makes Everett homes damp

Everett sits on a peninsula at the mouth of the Snohomish River along Port Gardner Bay, and its median home was built in 1980, so roughly half the housing stock predates that year and carries roofs, windows and plumbing that have seen decades of rain. Water reaches homes here in a few ways. During the December 2025 atmospheric river storms, the city prepared to close Riverfront Boulevard in North Everett's Riverfront neighborhood, and Ebey Island residents evacuated with dikes expected to overtop. In late December 2022, king tides flooded W Marine View Drive. For most houses, though, the steadier source is the long wet season: roof and window leaks, damp crawl spaces, and condensation on cold walls in rooms kept shut.

Signs to look for

• A damp, earthy smell in the basement or crawl space after rain.
• Dark growth on the underside of roof sheathing.
• Water lines or swelling at the base of walls in homes that took river or tide water.
• Mildew that keeps coming back on a bathroom ceiling.

Seasonal timing

River flooding on the Snohomish tends to come with winter storms, and king tides also arrive in winter, so those months bring the most urgent calls. After any flood, EPA says to assume mold where materials couldn't be dried within 24 to 48 hours, so book an inspection before anyone rebuilds. For routine concerns, a fall visit before the heavy rain catches problems early, while a midwinter visit shows condensation at its worst.
