West Bellevue and Somerset have many 1950s–1970s homes on crawlspaces and hillside lots. Lake Hills and Crossroads have mostly mid-century homes, and downtown has many high-rise condos. Many West Bellevue and Somerset homes sit on hillside lots with crawlspaces or daylight basements, where long rainy seasons and poor drainage lead to mold and wood rot. Downtown towers share plumbing stacks, so a leak in one unit can reach several floors below before anyone notices.

Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in Bellevue?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Bellevue Development Services.
Who pays for a condo leak in Bellevue?
It depends on the source and the association's bylaws. Document the damage and notify the association and your insurer quickly.
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.
