Sewage Backup Cleanup for Shoreline Owners, Landlords and Managers

Commercial sewage cleanup is the same biohazard work done in shops, restaurants, offices and apartment buildings, where many people share the space and the area must be cleared and sanitized before use resumes.

Call Shoreline Biohazard Cleanup Help any hour about a sewer backup in Shoreline, WA. You get an assessment of how far the sewage spread, removal and decontamination, and a chance to talk through insurance and landlord questions in King County.

King County carries a Very High river flood risk rating from FEMA, and rising water can overload sewer pipes and push wastewater back up through floor drains. About 65% of homes in Shoreline were built before 1980, and older clay or cast iron sewer pipes crack and clog with roots over time.

The work often covers:

  • Raw sewage removal from floors, basements, crawl spaces, garages and utility rooms
  • Disinfection of hard surfaces, framing and subfloors with EPA-registered products
  • Containment and negative air to keep contamination out of unaffected rooms
  • Decontamination of HVAC components and air paths when sewage odor has spread
  • Cleaning and sanitizing of salvageable furniture, appliances and stored belongings

How a Sewage Cleanup Company Works a Job in Shoreline, WA

1. Protect people first

Residents, tenants and staff are moved out of the area while the crew sets up protective gear and containment.

2. Pump and remove

Wastewater is taken out of the building, and standing liquid in crawl spaces or low corners is cleared.

3. Removal of porous materials

Carpet, padding, drywall and insulation that soaked up sewage are cut out, bagged and hauled away as contaminated waste.

4. Sanitizing and deodorizing

Remaining surfaces are washed and disinfected, and odor is removed at its source rather than covered up.

Sewer Backup Questions Answered for Shoreline, WA

Should I call a plumber or a cleanup company first?

If sewage is still coming up, a plumber may need to stop the source. If sewage is already on the floor, a cleanup team can start containing it at once. Many property owners call both, and it does not matter much which is first. Sewer backup companies and plumbers often work one after the other on the same job.

Who pays for sewage cleanup, the landlord or the tenant?

It depends on the cause, the lease and local law. A landlord's policy may cover the building, while a renter's policy may cover belongings. If the blockage was in a public sewer main, the city or utility may be responsible for the repair.

Can I clean sewage myself?

A very small spill on a hard floor can be handled with gloves, boots, eye protection and a disinfectant used by label directions. Anything that reached carpet, drywall or a large area needs professional cleanup, because hidden contamination is hard to see.

How do I know if sewage is leaking under my house?

Common signs include a sewer smell in the yard or crawl space, soft or damp ground near the foundation, gurgling drains and slow drains in several fixtures at once. A plumber can confirm the leak. Once it is found, a cleanup team can take care of the contaminated soil, materials and odor.

How much does a sewer backup cleanup cost?

The price depends on how much sewage there is, how far it spread and which materials must be removed. A bathroom overflow costs less than a flooded basement. The team sets the price after seeing the space, and nothing is decided on a call alone.

Can carpet be saved after a sewage backup?

Usually not. Carpet and padding soak up Category 3 water and cannot be reliably made safe, so they are cut out and discarded. Hard surfaces, sealed wood and items in closed containers can often be cleaned and kept.
