Basement waterproofing is the permanent answer to a basement that keeps getting wet: interior drainage channels, sump pump systems, crack injection, and moisture sealing engineered to redirect water before it reaches your floor. If there's standing water in the basement right now, extraction and structural drying come first — then waterproofing makes sure you never do this twice. Crews assess the water path (hydrostatic pressure, grading, foundation cracks), then build the drainage and pumping system that matches it.
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.

If water is standing now, extraction and drying come first — waterproofing installed over saturated materials seals the moisture in behind the new work.
