Sometimes a drain problem isn't a clog at all. A main drain that keeps backing up after cleaning, a persistent sewage smell, or soggy patches in the yard can point to a damaged pipe underground.
Scarborough Drain helps homeowners understand what's happening in their main line and what repair options make sense. We aim to give you a clear explanation, not a sales pitch, so you can decide on the right next step.
Signs your main drain may be damaged
- Repeated backups shortly after the line has been cleared
- Sewage odour indoors or near the front yard
- Wet, sunken or unusually green patches of lawn over the drain path
- Cracks in the basement floor near the drain line
- Pipe fragments or soil coming up during cleaning
What causes drain line failure
Older drain pipes made of clay or cast iron can crack, separate at joints or corrode with age. Tree roots exploit small openings and expand them over time. Ground movement, freeze-thaw cycles and heavy loads above the pipe can also cause sections to shift or sag, which leads to repeated buildup.
How we assess repair options
Repairs should start with a clear diagnosis. A camera inspection is usually the first step, showing the location, type and extent of the damage. From there, we can explain whether a localized repair is suitable or whether a larger section of the line needs attention.
We'll discuss the scope of work, what's involved, and pricing before any repair begins. Some repairs may require permits or coordination with the City of Toronto, depending on where the damage is located.
Your line vs. the city's line
In Toronto, responsibility for the sewer connection is generally divided at the property line, with the homeowner responsible for the private portion. If an inspection suggests the problem is on the city side, we'll let you know so you can contact the city.
When to call
If your main drain needs repeated cleaning or you've noticed any of the warning signs above, call us. Addressing a damaged line early can reduce the risk of a basement backup.

Frequently asked questions
How do you know if a drain needs repair or just cleaning?
A camera inspection shows the inside of the pipe and whether there are cracks, separated joints, sags or roots. That determines whether repair is needed.
Does main drain repair always require digging?
Not always. The best method depends on the pipe's condition, depth and location. We'll explain the options after assessing the line.
Who is responsible for the drain under the sidewalk?
Generally, the city is responsible for the portion on public property. We can help you understand where a problem appears to be.
Can you give me pricing before work starts?
Yes. We discuss scope and pricing with you before any repair work begins.
