What Our Sewer Backup Service Includes
Every sewer backup project is unique — here's the full scope of what we handle for Toronto and GTA properties.

Our Sewer Backup Process
Step-by-step breakdown of how our team handles sewer backup from initial call to final walkthrough.
Emergency Response
Our biohazard-trained crew arrives within 45 minutes with full PPE and containment equipment. We establish safety zones and begin immediate sewage extraction to minimize contamination spread.
Containment & Extraction
Contaminated water is extracted using specialized pumps. Affected porous materials (carpet, drywall, insulation) are removed and safely disposed of following biohazard protocols.
Sanitization & Disinfection
All affected surfaces are treated with hospital-grade antimicrobial solutions. We use ozone generators and HEPA air scrubbers to eliminate bacteria, viruses, and odours throughout the space.
Drain Diagnosis & Repair
We perform a drain camera inspection to identify the root cause — tree root intrusion, pipe collapse, blockage, or municipal backup — and execute the necessary repair to prevent recurrence.
Structural Drying & Restoration
Industrial dehumidifiers and air movers dry the structure to verified safe moisture levels. We then restore walls, floors, and fixtures to pre-damage condition.
Prevention & Insurance
We recommend and install backwater valves and sump pump systems to protect against future backups. Complete documentation is provided for your insurance claim with direct billing available.
Sewer Backup Questions & Answers
Common questions Toronto homeowners ask about our sewer backup services.
Q. Is a sewer backup a health hazard?
Yes. Sewage is IICRC Category 3 "black water" and can carry E. coli, hepatitis A and other pathogens. Keep people and pets away from the area and call 416-988-3539 — our crews arrive in PPE with containment and hospital-grade disinfectants to remediate it safely.
Q. What causes sewer backups in Toronto homes?
Common causes include heavy-rain sewer surcharge, tree-root intrusion in older clay laterals, grease and flushable-wipe blockages, and municipal main backups. Homes without a backwater valve are the most frequently affected during summer storms.
Q. Can you stop it from happening again?
Yes. After cleanup we can install a backwater valve and, where needed, a sump pump and pit, both of which the City of Toronto offers a basement-flooding protection subsidy toward. We also camera-inspect the line to catch root intrusion early.
Q. What gets thrown out after a sewage backup?
Porous materials saturated with black water — carpet, underpad, drywall below the flood line, insulation and upholstered items — are removed and disposed of safely. Hard, non-porous surfaces are cleaned, sanitised and verified with testing rather than replaced.
Q. Does insurance cover sewer backup cleanup?
Only if you carry a sewer-backup endorsement, which most Ontario insurers offer for roughly $50–$150 a year. If you have it, we document the loss and bill your insurer directly; if not, we provide a clear written estimate up front.
Q. How long does sewer backup cleanup usually take?
Sewer backup cleanup usually takes two to four days, covering extraction, disinfection, and structural drying, though timing depends on how far the contamination spread and what materials were affected. Because sewage is a category 3 contamination, we prioritize thorough disinfection over speed, using antimicrobial treatments and monitoring air and moisture levels throughout your GTA home before we call the job complete.
Q. Do you clean up sewer backups in commercial and industrial buildings?
Yes, Pro Max Restoration cleans up sewer backups in commercial and industrial buildings as well as homes throughout the GTA. Commercial sewage events often involve larger volumes and multiple drains or fixtures, so we scale up extraction and disinfection equipment accordingly and work around your operating hours to limit business disruption where possible.
Q. What equipment do you use to disinfect a home after sewage backup?
We disinfect a home after a sewage backup using hospital grade antimicrobial and antibacterial treatments, HEPA air scrubbers, and negative air containment to control airborne contaminants during cleanup. Contaminated porous materials are removed rather than just cleaned, and remaining structural surfaces are treated and re-tested before drying equipment and moisture monitoring confirm the space is safe.
Q. Can I stay in my house while sewer backup cleanup is underway?
It depends on how far the sewage spread, since areas under active decontamination are sealed off with containment barriers for safety. Many homeowners can stay in unaffected parts of the house, but if the backup reached living space or HVAC systems, we may recommend staying elsewhere until disinfection and air quality checks are complete.
Q. How soon can a crew reach my home after a sewer backup?
A crew can typically reach your home within about 45 minutes of your call, since sewer backups are treated as a health hazard emergency and dispatched 24/7/365. Call 416-988-3539 as soon as you notice a backup, avoid contact with the affected area, and our technicians will begin containment and extraction as soon as they arrive.
