The Cedar River and Renton flooding
The Cedar River runs through the middle of Renton to Lake Washington, and it can rise fast in long winter storms. On December 11, 2025, after days of atmospheric river rain, the Cedar River in Renton crested above its 1990 record. Water covered SE Jones Road and entered homes there, residents in the Maplewood area sandbagged a breach point near SR-169, and the National Weather Service warned that the area around the Renton Airport was especially at risk.
Away from the river, the same storms flood basements and crawl spaces, overload storm drains, and push water through roofs and windows on the Highlands, Benson Hill and Kennydale hills.
If your home or business took on floodwater, treat the water as contaminated. Wet drywall, insulation, carpet and pad usually have to be removed, and the structure cleaned, disinfected and dried before repairs. Doing it within 24–48 hours keeps mold from starting.

Renton restoration FAQs
Do you clean up after Cedar River flooding?
Yes. We pump out water, remove contaminated materials, clean and disinfect, dry the structure and document the loss for your insurance or FEMA claim.
How fast can you get to Renton?
We respond 24/7 from Federal Way. Our average response time is 45 minutes.
My basement flooded but the river didn’t reach my street. Is that still flood damage?
For insurance, the source matters. Groundwater or surface water coming in is usually treated as flooding, while a burst pipe or failed water heater is usually covered by homeowners insurance. We note the source in our documentation.
Can mold start after a flood?
Yes. Materials that stay wet for more than 24–48 hours can grow mold. Fast drying, and removing what can’t be dried, prevents it.
