Sewage cleanup for Oshawa and the GTA, treated as biohazard work from step one
Sewage backup isn't a bigger version of a water leak, it's a different category of job. We scope it, price it, and clean it that way.

Why sewage cleanup quotes should never look like standard water damage quotes
If a sewage backup quote looks like a slightly upgraded version of a regular water mitigation quote, that's a sign something's being skipped. Category 3 water, which is what sewage backup is, requires different handling from source to disposal.
Contact materials often need full removal, not drying
Porous materials that contact sewage, like drywall, carpet, and insulation, typically can't just be dried and reused the way clean-water-affected materials can. Pricing that treats sewage like a standard water job usually misses this.
Older GTA sewer lines back up differently than newer ones
Aging clay or cast iron laterals common in older Durham and Toronto neighbourhoods are more prone to backups during heavy rain events, and the backup pattern affects how far contamination spreads through a basement.
Disinfection is a separate step from cleaning
Wiping down a surface is not the same as disinfecting it to the standard sewage contact requires. We treat these as two distinct steps in the scope, not one line item.
Disposal has its own requirements
Contaminated materials need to be bagged, removed, and disposed of appropriately, which takes real time and should show up as its own line in the quote.
The cheapest sewage cleanup quote is usually the one skipping disinfection or disposal steps
Because sewage cleanup work is unpleasant and time-consuming to do properly, some quotes shortcut it: extract, deodorize, call it done. That leaves contamination in flooring seams, baseboards, or subfloor that surfaces later as odour or health complaints.
We scope extraction, disposal, and disinfection as three distinct steps
Our sewage cleanup quotes break out contaminated material removal, proper disposal, and disinfection separately, so you can see exactly what's being done at each stage rather than trusting a single flat number to cover it all.
Our sewage cleanup process
Handled as a biohazard job from the first call to final disinfection.
- 1
Contain the affected area
We isolate the contaminated zone first to prevent spread to unaffected parts of the home.
- 2
Extract sewage and remove contact materials
Standing sewage is removed, and porous materials that contacted it are identified for disposal rather than drying.
- 3
Dispose of contaminated materials properly
Removed materials are bagged and disposed of according to proper handling standards.
- 4
Disinfect the affected area
Surfaces are disinfected to a standard appropriate for Category 3 water contact, separate from general cleaning.
Why our sewage cleanup scope is different
This is the job where cutting corners has real health consequences, not just cosmetic ones.
We treat it as Category 3 water
Sewage cleanup gets its own protocol, not a modified version of a standard water job.
We separate disposal from cleaning
Contaminated material removal is its own scoped step.
We disinfect, not just deodorize
Odour control isn't a substitute for proper disinfection.
We understand older GTA sewer infrastructure
Backup patterns from aging laterals inform how we check for spread.
We document disposal
Records of what was removed and how, for your peace of mind.
We carry coverage suited to biohazard work
Insurance that reflects sewage cleanup specifically.
Sewage cleanup questions
Is sewage backup covered differently than a regular water damage claim?
That depends on your specific insurance policy, but many insurers do treat sewage backup as a distinct category. We document the job in a way that supports whatever claim process you're going through.
Can carpet or drywall that touched sewage be cleaned instead of replaced?
Generally, porous materials that contact sewage need to be removed rather than dried and reused, both for health reasons and because disinfection can't fully penetrate some porous materials once contaminated.
Why does sewage cleanup cost more than a regular flood cleanup?
Because it involves extra steps: contact-material disposal and full disinfection, on top of extraction. A quote that matches a regular flood cleanup price is often skipping one of those steps.
How fast do you respond to sewage backup calls?
We prioritize sewage calls given the health risk involved. Email us your situation and location and we'll give you a straight answer on timing.
Do older homes in Durham Region have more sewage backup issues?
Older clay and cast iron sewer laterals, common in older Durham and Toronto neighbourhoods, are more prone to backups during heavy rain, so yes, we see this pattern regularly in that housing stock.
