GaiaCrete®, the premium hempcrete alternative, is built for Seattle's climate — permanently mold-proof, zero VOCs, and 30-50% lower energy costs.
Seattle's Pacific Northwest climate delivers 150+ rainy days per year, persistent overcast conditions, and the kind of slow, steady moisture exposure that destroys conventional insulation from the inside out. Homes across Capitol Hill, Ballard, Fremont, and Eastside suburbs develop hidden mold problems at rates far above the national average.

Seattle's constant moisture creates the highest mold risk of any major US city. Most PNW homes have hidden moisture damage that standard inspections don't catch. A Healthy Home Assessment uses thermal imaging to find moisture intrusion and lab-grade testing to measure mold spore counts.
