Mold Removal in Kent, WA

Valley floor and two hills

Kent is one of the largest cities in south King County, about 17 miles south of Seattle. Its layout explains a lot. The Green River valley floor is mostly industrial and commercial, with some medium-density housing. West Hill mixes homes and businesses along I-5. East Hill is primarily residential and has Lake Meridian, the city's largest lake, along with Clark Lake, Lake Fenwick and the Panther Lake area. SR 167 runs through the valley.

The Green River

The Green River flows north through Kent toward Puget Sound. Before Howard A. Hanson Dam was built at Eagle Gorge in 1962, flooding from the Green and White rivers was a constant problem in the valley. King County says the lower Green, including Kent, is still at risk of flooding in residential, commercial and industrial areas. The dam and a system of levees and revetments reduce that risk, but not all flooding can be prevented.

That was clear in the December 2025 atmospheric river flooding. A levee failed after a week of heavy rain and King County ordered evacuations in parts of Kent, Auburn and Tukwila. The Army Corps stored a record volume of water behind Hanson Dam during back-to-back storms to protect Kent, Auburn, Renton and Tukwila.

If water got in, act on EPA's timeline: dry within 24 to 48 hours, or treat soaked materials as moldy. Children shouldn't help with flood cleanup, and adults should wear at least an N-95.

On the hills

Most East Hill and West Hill homes never see river water. Their mold usually traces to roofs, bathrooms, crawl spaces and windows during the long October-to-April wet season. A stain that grows after rain points to the roof or gutters; one that grows in cold weather points to condensation. Keeping indoor humidity under 60 percent, as EPA recommends, prevents a lot of it.

Permits, rentals and health

Kent is an incorporated city, so building permits for rebuild work come from the City of Kent rather than King County; ask the city which repairs need one before walls go back up. Renters should give the landlord written notice about leaks or moisture. Under Washington law, the landlord has set times to start repairs, up to 10 days for most problems. Public Health - Seattle & King County offers indoor air quality and mold consultations.

Hiring

Washington has no mold license. Anyone doing construction or repair work must be registered with L&I; look the company up on the Verify a Contractor tool. When you call, you'll be connected with an independent local company that can assess the damage.
