Severely flooded Toronto basement with brown standing water covering the entire floor — emergency flood cleanup required immediately
Health Hazard — Category 3

Sewer Backup Cleanup: What You Need to Know

Toronto receives 780mm of rain per year plus significant spring snowmelt. During major storms, the city's combined sewer system becomes overwhelmed and water enters homes through floor drains, foundation cracks, and window wells. Basement flooding is one of the most common homeowner emergencies in the city — and one of the most time-sensitive.

When you call us, we arrive with truck-mount extractors that remove hundreds of gallons per hour, commercial air movers, and dehumidifiers calibrated to Ontario's humidity. We treat every flood job as a full restoration project — not just a cleanup. See our guide on top causes of basement flooding in Toronto.

Signs of a Sewer Backup in Your Toronto Home

  • Standing water in your basement — even a few inches causes structural damage if left
  • Water entering through foundation walls or floor drains during or after rain
  • Saturated carpeting, drywall, or insulation — household fans cannot dry these materials
  • Discoloured or contaminated water — may require Category 3 decontamination
  • Electrical panels or outlets near the water line — do not attempt DIY entry

Step by Step

Our Sewer Backup Cleanup Process

1

Safe Containment

We seal the affected area with containment barriers and establish negative air pressure immediately. Our crew wears full PPE throughout to prevent cross-contamination to unaffected rooms.

2

Water Extraction

Truck-mount extractors remove standing water fast — including from carpets, padding, and porous materials that appear dry on the surface. Far more powerful than any portable unit.

3

Hospital-Grade Disinfection

All non-porous surfaces are treated with hospital-grade antimicrobial disinfectant. HEPA air scrubbers run throughout the process and for hours after material removal to clear airborne contaminants.

4

Mold Prevention & Report

We test air quality before removing containment and issue a full clearance report for your insurance claim. Sewer backup is typically covered by Ontario home insurance.

Why Choose Us

Why Sewer Backup Requires IICRC Certified Professionals

Industrial Extraction Equipment

Our truck-mount extractors are permanently mounted in our service trucks — powered by the truck engine. 10x the suction of portable units. We remove water from carpet padding, subfloor, and concrete that portable equipment misses.

Thermal Camera Moisture Mapping

We scan every wall and floor before and after drying using thermal cameras. Hidden moisture pockets are found and dried completely — not left to become mold problems inside your walls.

Full Insurance Documentation

Photos, moisture logs, and a full scope of work — everything your adjuster needs from Intact, Aviva, TD, and Desjardins. We communicate directly with your insurer. Read our Ontario insurance guide.

Common Questions

Questions About Sewer Backup Cleanup

Yes — in most cases. Sewer backup coverage is a standard endorsement on Ontario home insurance. Coverage limits vary by policy. See our guide: sewer backup vs flood damage coverage.

We strongly advise against it. Category 3 water contains live pathogens. Without proper PPE and containment, you risk spreading contamination and serious illness. This is not a standard cleanup job.

Initial containment and sewage removal is completed the same day. Decontamination, drying, and air quality testing takes 3 to 5 days. Structural material replacement is a separate phase we document for your insurer.

Standard Ontario home insurance covers sudden water damage from internal sources. Overland flooding requires a separate endorsement that many homeowners added after the 2013 Toronto flood. Read our Ontario water damage insurance guide — we also advise on your specific policy at no charge.

Yes — mold can begin growing within 24 to 48 hours in Ontario's humidity. Our antimicrobial treatment and complete drying process is designed to prevent mold before it starts. See our guide: how fast mold grows after water damage.

Yes. We serve all Oakville FSA zones including Glen Abbey (L6M), East Oakville (L6J), and Central Oakville (L6K). See our full Oakville service area.
