Crawl space waterproofing stops the cycle of standing water, damp soil, and humid air under your home: drainage to move water out, a sealed vapor barrier to stop soil moisture, and dehumidification to control the air. Wet crawl spaces feed mold on joists, rot in subfloors, and musty air upstairs — waterproofing addresses the water at its entry point instead of treating symptoms above. If the space has standing water today, removal and drying come first, then the system that keeps it out.
Ketchikan context: Ketchikan is among the wettest cities in the United States, receiving approximately 150 inches of annual rainfall in its temperate rainforest climate on Revillagigedo Island. Ketchikan Creek and Ward Creek frequently overtop their banks during Pacific storm events, and the steep mountainous terrain surrounding the city channels enormous volumes of runoff directly into residential structures. The combination of near-constant moisture and older wooden construction makes mold proliferation after water intrusion an especially acute and rapid concern.
