How a Sewage Cleanup Company Works a Job in Columbia City, Seattle, 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. Isolate and protect

Plastic barriers and air controls go up, and technicians suit up before they enter the sewage area.

3. Sanitize the structure

Framing, subfloor and concrete are cleaned and treated, since sewage can soak into surfaces that look dry.

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 Columbia City, Seattle, 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.

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.

Do sewage cleanup companies handle commercial properties?

Yes. Commercial sewage cleanup in restaurants, offices, shops and apartment buildings follows the same biohazard steps, with added attention to keeping part of the building usable and to documentation for managers and insurers.

What illnesses can raw sewage cause?

Sewage can carry germs such as E. coli, norovirus, hepatitis A and Giardia. They spread through skin contact, splashes and hand to mouth contact. Washing well and wearing protection reduce the risk, but removal by a crew reduces it most.

How long does it take to get sick from raw sewage?

Symptoms such as stomach cramps, vomiting and diarrhea can start within hours or take a few days. Anyone with symptoms after exposure should contact a doctor. Children, older adults and people with weak immune systems are at higher risk.

How do I clean sewage off concrete?

Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.
