Sewage Backup and Leak Cleanup, Seattle
Get it out. Disinfect everything. Make the space safe again.
In Seattle, sewage backups usually show up in the basement first. The floor drain or the basement toilet is the lowest fixture in the house, so when the side sewer clogs or the system is overloaded in a heavy storm, that is where it comes up.
Our crew works in OSHA-compliant protective gear under the IICRC S500 Category 3 protocol. We extract the water, remove contaminated carpet, pad and drywall, disinfect every affected surface and dry the structure. Then we rebuild and document everything for your carrier.

Seattle sewer lines
Why sewage backs up in Seattle basements.
The age of the house and the age of the sewer system both play a part.
You own the side sewer
In Seattle, the side sewer from your house to the city main is the property owner’s responsibility. Older clay side sewers crack, sag and let roots in over time.
Heavy rain and older systems
Parts of Seattle have older sewer systems that carry stormwater too. In long, heavy storms they can back water up into the lowest drains in the house.
Basement fixtures
Floor drains, basement toilets and laundry sinks sit at the lowest point. A backwater valve can help, and we can point you to a plumber who installs them.

Our process & equipment
Sewage cleanup backed by the right equipment
Sewage carries bacteria and viruses, so the job is about containment and disinfection as much as drying. The equipment reflects that.
- Commercial-grade equipment
- IICRC trained technicians
- Healthier, safer results
Containment & air filtration
Plastic barriers and HEPA air scrubbers keep contamination and odor from reaching the rest of the house.
Disinfection & drying
EPA-registered disinfectants, then dehumidifiers and moisture meters to confirm the structure is clean and dry.
Restoring today. Protecting tomorrow.It’s in our nature to do it right.

Sewage cleanup FAQs
We’re here to make it easy.
How fast can you get to a sewage backup around Seattle?
We run crews 24/7 and are typically on site within 45 minutes in South Seattle and the nearby cities. Stop running water in the house and keep everyone out of the basement until we arrive.
Who fixes the side sewer?
A licensed side sewer contractor or plumber clears or repairs it. We handle the cleanup and rebuild, and we can recommend a contractor. We make sure the line is fixed before we close up walls.
I manage a rental property. Can you work with tenants?
Yes. We schedule with tenants, explain what to expect, keep the work area contained and send you photos and a written scope.
Why is sewage called black water?
Sewage is Category 3 water, the most contaminated kind. It carries bacteria, viruses and other pathogens, so anything porous it soaks, like carpet, pad and drywall, usually has to be removed rather than dried.
Can I clean up a small sewage backup myself?
A small overflow on tile from a toilet with nothing solid in it may be manageable with gloves and disinfectant. Anything that reached carpet, drywall, a crawl space or more than one room needs a crew with protective gear and the right disinfectants.
Does homeowners insurance cover sewage backup?
Many policies only cover sewer backup if you have a specific endorsement for it. Check your policy or call your agent. We document the source and the damage either way, and bill the carrier directly when it's covered.
