Mycotoxins in the Home: Separating Signal from Marketing in Washington
Mycotoxins are among the most misunderstood — and most aggressively marketed — topics in this field. This guide covers what they are, how they behave in buildings, what home testing can show, and why fogging products claiming to destroy them deserve skepticism.
What Washington changes about the picture
Marine west coast west of the Cascades: long wet season, low drying potential. Western Washington's wet season punishes marginal flashing details; crawl spaces stay damp for months without intervention.
Protocols are national; moisture is local. In Washington, the pressure a building lives under comes from specific, predictable directions — and this protocol should be read with those directions in mind, because they decide where the risk concentrates, which assemblies fail first, and what a defensible local scope looks like.
The WA moisture drivers to read this against
- Months of rain with minimal drying windows
- Crawl space moisture
- Window and siding envelope leaks
What never changes — anywhere
What stays constant in Washington is the discipline: find the moisture, test honestly, correct the water before the growth, remediate under containment to the sensitized-occupant standard, and let an independent verifier — not the contractor — decide when it is done.
The full protocol below covers the national playbook in depth — read it alongside the WA context above.

Washington questions
Does this protocol change in Washington?
The sequence never changes — locate moisture, test honestly, fix water before mold, remediate under containment, verify independently. What changes in Washington is where the moisture pressure comes from: months of rain with minimal drying windows That determines where instruments go first and which assemblies earn suspicion.
What should Washington households check first?
Start with the failure modes this housing stock is known for. Western Washington's wet season punishes marginal flashing details; crawl spaces stay damp for months without intervention. A moisture-focused assessment that ignores those patterns is guessing.
Can I get matched with a vetted provider in Washington?
Yes — matching runs in all 50 states. Every provider is vetted on containment discipline, fine-particle competence, and willingness to be independently verified. Matching is free for households.
