This Is a Health Emergency, Call Before You Touch Anything
Raw sewage is the most contaminated water you can have indoors. It carries bacteria like E. coli, along with viruses and parasites that cause serious illness through contact, contaminated surfaces, and airborne particles. Children, older adults, and anyone with a weakened immune system are at the highest risk, and in a business or rental, exposed occupants and staff become your liability.
The longer it stays, the worse it gets. Contaminated water wicks into walls, flooring, and contents within hours, and mould can begin to grow on wet, soiled materials within 24 to 48 hours, according to Health Canada and CMHC. Do not wade in, do not start mopping, call us, keep people and pets out of the affected area, and let a trained crew handle it safely.
What Sewage Backup Restoration Covers
Sewage backup restoration is the safe removal, disinfection, and rebuilding of any area contaminated by sewage or other heavily soiled water. It is far more than cleanup, it is biohazard remediation. A complete job includes:
- Containing the contaminated zone and protecting unaffected areas
- Extracting standing sewage and contaminated water
- Removing and disposing of porous materials that cannot be saved, drywall, carpet, padding, insulation, and affected contents
- Cleaning and disinfecting all salvageable surfaces and the structure
- Drying, deodorizing, and controlling moisture to prevent mould
- Reconstructing what was removed back to a finished, livable space
The goal is to return your property to pre-loss condition or better, clean, dry, safe, and fully restored.
Sewage Is Black Water, a Genuine Biohazard
Restoration professionals classify sewage as the most contaminated category of water there is, often called black water. It is not dirty water you can rinse away. It is a hazardous mix of human waste, pathogens, and chemicals that demands containment, protective equipment, and professional disinfection, not a mop and a bottle of cleaner.
- Pathogens: E. coli and other bacteria, plus viruses and parasites that cause gastrointestinal and respiratory illness.
- Porous materials are lost: drywall, carpet, insulation, and soft contents that touch sewage cannot be cleaned and dried, they must be removed and disposed of.
- Spreading contamination: walking through it or fanning the air pushes pathogens onto clean surfaces and into the air you breathe.
This is exactly why sewage damage is not a job to take on yourself.
What Has to Go, and Why Drying Alone Is Not Enough
With clean water, much of what gets wet can often be dried and saved. Sewage is different. Once porous materials absorb contaminated water, the bacteria and pathogens are inside them, and no amount of surface cleaning or drying makes them safe again. Trying to keep them simply traps the health hazard inside your walls and floors.
That is why proper sewage restoration removes and disposes of affected porous materials, then disinfects and dries the structure that remains before anything is rebuilt. It is more demolition than a typical water loss, but it is the only way to make the space genuinely safe for your family, tenants, or staff to return to.
How Firstline Handles a Sewage Backup
Why You Should Not Clean This Up Yourself
It is tempting to grab a shop vac and deal with it, especially in a basement you rarely use. The problem is that sewage exposes you and everyone in the building to disease, and ordinary household tools and cleaners cannot disinfect a contaminated structure or safely dispose of biohazardous material. A single splash, a contaminated surface left behind, or wet drywall that gets dried instead of removed can keep the hazard alive long after the water is gone.
There is no upside to the risk. Proper crews use protective equipment, containment, and professional disinfection precisely because the danger is real. Protect your family, tenants, or staff and let a trained team handle the contamination, that is the safe choice, every time.
Homes and Businesses
In your home, a sewage backup most often hits the basement, through a floor drain, a backed-up municipal sewer, a blocked or collapsed drain line, or a failed sump pump. We get your family out of harm's way, remove the contamination, and rebuild the space so it is safe to use again, not just dried out.
For businesses and managed properties, a sewage event means closed units, exposed occupants, and real liability. We work fast and discreetly to contain the area, keep the rest of the building usable where possible, document everything for ownership and insurers, and coordinate with property managers and adjusters so the restoration moves without finger-pointing across multiple trades.
We Document the Loss So the Claim Is Built Right
Carriers pay for what is documented, not for what was actually damaged. From the first call, we photograph, scope, and record the full extent of the contamination and the materials that had to be removed, so your claim reflects the real loss instead of an under-counted estimate.
We are a restoration contractor, not a public adjuster or a lawyer, and we cannot promise an outcome. What we control is the file. We manage the claim from first notice of loss to final payment and help you pursue the full value you're owed. See our insurance claim restoration assistance. We work directly with your insurance company and bill them directly where the carrier allows it. On a covered claim, insurance pays for the approved work and you normally pay only your deductible.
