Sewer Line Repair
Home › Plumbing Services › Sewer Line Repair

A damaged sewer line can cause repeat backups, sewage odours and even flooding in your basement. Plumber On Demand inspects the line with a drain camera first, so the repair is scoped to the real problem instead of guesswork.
Sewer line problems we repair
- Tree root intrusion through joints and cracks in older clay and cast iron pipe
- Cracked or broken pipe from age, ground movement or heavy loads
- Sagging sections where waste collects and causes repeat clogs
- Offset or separated joints that catch debris and let water escape
- Collapsed lines that stop drainage completely
- Repeat main drain backups that keep returning after cleaning
Camera inspection first
Before we recommend any repair, we run a camera through the sewer line to see its condition and locate the problem. You see what we see, and we explain what it means. This shows whether the line needs cleaning, a spot repair of one section, or a larger replacement, so you only pay for the work that actually fixes it.
Repair options
Depending on the damage and where it is, repairs can range from clearing roots and debris to replacing a damaged section or the full line from the house to the municipal connection. We explain the options, the disruption to your yard or floor, and the cost of each before work begins.
Signs of a sewer line problem
Multiple drains backing up at once, gurgling from toilets or floor drains, sewage smells in the basement, and unusually green or soggy patches in the yard can all point to a sewer line issue. Our drain services page covers drain cleaning and backwater valves as well.
Sewer Line Repair FAQs
How do I know if my sewer line is damaged?
Repeated backups in more than one fixture, sewer odours, gurgling drains and wet patches in the yard are common signs. A camera inspection confirms it.
Can tree roots really break a sewer pipe?
Yes. Roots enter through small cracks and joints looking for water, then grow and widen the opening until they block or break the pipe.
Who is responsible for the sewer line?
The property owner is usually responsible for the line from the building to the property line, and the municipality for the part beyond it. Rules vary by municipality.
