Why DIY is a bad idea
Sewage contains E. coli, hepatitis A and other pathogens. Household cleaners don't reach what's absorbed into drywall and carpet. Improper cleanup can leave contamination behind and complicate your insurance claim.
Municipal vs. private line
Sometimes the blockage is in the city's sewer, sometimes in your private lateral. We document the backup so you, your plumber and your insurer can sort out where it started.
How much does sewage backup cleanup cost?
Typical 2026 ranges for emergency mitigation in the GTA: extraction, drying and any tear-out needed to dry the structure. Your real number depends on how much water, what kind, how long it sat and what it soaked into. We give you a written, itemized estimate on site and can work directly with your insurance adjuster.
| Situation | Typical mitigation cost* | Typical drying time |
|---|---|---|
| Sewer backup in a finished basement (Category 3) | $7,000 – $15,000+ | 4 – 6 days |
*Emergency mitigation only, before HST. Rebuild (new drywall, flooring, paint, cabinets) is a separate estimate. Read the full water damage cost guide.

How we handle sewage cleanup
Contain
We set up containment and negative air so contamination doesn't spread to the rest of the house.
Remove
Sewage is extracted and porous materials it touched — carpet, underpad, drywall, insulation — are safely removed and disposed of.
Clean & sanitize
All hard surfaces are cleaned and treated with EPA-registered antimicrobials.
Dry & verify
Structural drying, then verification that the space is clean and dry before rebuild.
Rebuild
New drywall, insulation and flooring, and advice on backwater valves so it doesn't happen again.
Sewage Cleanup questions
Is it safe to stay in my home during sewage cleanup?
In most cases the affected area is contained and you can stay in the rest of the house. Young children, older adults and anyone with a weakened immune system should keep away from the affected area.
Is sewer backup covered by insurance in Ontario?
Often only if you have a sewer backup endorsement on your policy. Check with your insurer — and we'll document everything either way.
