When a kitchen sink overflows on Mercer Island, WA, local crews respond fast to contain the water, following IICRC standard methods to dry the floor, cabinets, and structure to prevent mold.

A crew reaches Mercer Island quickly to check that the sink is off and the clog is contained. They map how far water traveled across the kitchen floor and into the cabinet base.
Technicians extract all standing water from the floor and the cabinet's interior. They also address any water that pooled in an adjacent room or dripped into a ceiling cavity below.
Using air movers and dehumidifiers sized for the space, the team dries the cabinet, subfloor, and wall base. They open cavities as needed to ensure thorough drying.

Kitchen sink overflow cleanup in Mercer Island usually runs from about $700 to $3,000, depending on how far the water traveled, whether the cabinet and subfloor stayed wet, and if a ceiling below was affected. A contained overflow caught quickly sits low, while water that swelled cabinets and reached a lower-level ceiling sits higher. The crew documents moisture readings and photos so the homeowner can submit the loss to the carrier.
