Why sewage is treated as a Category 3 loss

A sewage backup is classified as Category 3 black water, meaning it carries bacteria, viruses and parasites. Anything porous it contacts — carpet, pad, drywall, insulation, some cabinetry — is contaminated and is removed rather than dried in place, because drying cannot make those materials safe again.

Containment, protection and disposal

We isolate the affected area, hold it under negative air pressure and work in full PPE so contamination is not tracked through the rest of the home. Contaminated materials are bagged, removed and disposed of properly, and hard surfaces are cleaned and treated with an EPA-registered disinfectant.

Drying and verification

Once the contaminated material is out, the structure that remains is dried with commercial dehumidifiers and air movers, and moisture is measured daily until the assemblies reach a verified dry standard. Reconstruction starts only after the space is both dry and clean.

Keeping it from happening again

Backups usually have a cause: a blocked or root-invaded lateral, a failed check valve, or a combined main that surcharges during heavy rain. We note where the line is blocked and what failed, so the plumbing side can be corrected and the same loss does not repeat at the next storm.

Sewage Cleanup in Clyde Hill: local conditions

Clyde Hill is a small residential city of large wooded lots and custom homes on a ridge above Lake Washington. Mature trees and hillside drainage are recurring concerns, and the mix of older and newly built homes brings both aging pipes and modern appliance failures. For sewage cleanup work in Clyde Hill, the condition we plan around most is hillside runoff and drainage.
