Crawl Space Mold Removal in Camano Island, WA

Does Camano really get flooding without big rivers?

It does, just not the river kind. Island County says that although it lacks major rivers, flooding generally comes in winter when intense storms line up with high tides, wind-driven waves frequently overtop shore protection, and lakes and other low-lying areas flood more often but less severely. Camano has shoreline on Saratoga Passage to the west, Port Susan and Davis Slough to the east and Skagit Bay to the north. In the late December 2022 king tide and coastal storm, Camano Island State Park flooded and closed its boat launch for several days, and Cama Beach State Park closed its cabins when water came within an inch of some front doors. Homes near beaches such as Juniper Beach or Madrona Beach, or near low spots inland, can see water reach the crawl space in events like that.

What if there's no flooding, just a smell?

That is the more common case. Most Camano crawl spaces never see seawater; they simply sit over soil that stays damp from October to April. Moisture rises through bare dirt or a torn ground cover, condenses on cool joists, and soaks the insulation. Cabins and second homes that sit closed and unheated through winter are especially likely to develop growth, because nothing is pushing that damp air out. A musty smell when you open the house is often the first sign.

Who handles repairs and permits on the island?

Camano is unincorporated, so building permits come from Island County Planning & Community Development's Building Department, which has an office at the Camano Annex on North East Camano Drive. You won't need a permit to clean mold off joists, but replacing rotted framing or doing work in a mapped flood zone can bring the county's flood damage prevention standards into play. Washington has no state mold license or certification, so check that any company is registered with Washington L&I as a construction contractor on the Verify a Contractor tool.

One local note

After a storm or king tide, check the crawl space as soon as it is safe and start drying wet materials within 24 to 48 hours. Soaked insulation rarely recovers and is better pulled than left to dry against the subfloor. For general health questions, Island County Public Health and the Washington Department of Health's mold page are good starting points.
