Cold snaps freeze pipes, and summer wildfires bring smoke into homes.

Sewage & Biohazard Cleanup questions
How can I prevent mold in a Washington home?
Run bath and kitchen fans, keep gutters clear, maintain a vapor barrier in the crawlspace, and fix leaks quickly.
How do I verify a Washington contractor?
Search the Washington Department of Labor and Industries contractor lookup for registration, bond and insurance.
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.
