Mold Removal & Remediation in Seattle, WA
Containment, HEPA filtration, and antimicrobial treatment remove mold colonies at the source and stop cross-contamination through the rest of the home. Mold remediation removes affected porous materials and corrects the moisture source that allowed growth. The work is done under containment with HEPA filtration so spores are not carried into unaffected rooms, and the area is cleared only once the underlying moisture problem has been resolved.
Remediation is the step after the assessment, not before it. A local pro establishes how far the growth extends and what is feeding it, because removing what is visible while the moisture source is still running puts the same colony back in the same wall. Texas and several other states also set a square-footage point above which the work has to be done by a licensed remediator — the service note below covers where that line falls in this city.

Frequently asked questions
There is no leak anywhere, so why is there mold on the wall?
In this climate it is often condensation rather than a leak. Through the wet season indoor humidity stays high and exterior walls stay cool, so moisture condenses on the cool surface, particularly behind furniture on a north-facing wall where air does not move. The fix is ventilation and humidity control, not a repair.
Why does the rain here cause trouble when the totals are not extreme?
Because it is the duration that matters, not the intensity. Thirty-eight inches spread across a long grey season keeps siding, roofing and framing continuously damp, and materials that never get a dry spell degrade in ways they would not under heavier but occasional rain.
Is a daylight basement a particular risk on a Seattle hillside?
It can be. Cutting a room into a slope puts one wall permanently against uphill soil, and that soil holds water through the wet months. Without functioning perimeter drainage the wall is holding back a saturated bank, and the first sign is usually damp at the base rather than a visible flow.
