Heavy rain saturates hillsides and floods basements. Older parts of Seattle have combined sewers that can back up during heavy storms.
Craftsman and Tudor homes with basements are common, along with many new townhomes and apartments. Many Seattle homes have converted basements or attached accessory dwelling units, so water damage often affects separate living spaces. Newer townhomes have stacked bathrooms and roof decks, where failed membranes and drains lead to leaks. Older homes in Ballard and Wallingford often sit on lots with poor drainage, where basements stay damp most of the rainy season.
Licensing in Washington: Washington requires contractors to register with the Department of Labor and Industries (L&I). Check the registration and bond on L&I's website.

Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in Seattle?
Structural, plumbing and electrical repairs need permits from the Seattle Department of Construction and Inspections.
How do I verify a Washington contractor?
Search the Washington Department of Labor and Industries contractor lookup.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
