Sewer Line Replacement & Excavation in Montreal
Repeated backups and slow drains across your whole home often mean a failing sewer line. We diagnose and replace old, cracked, or collapsed sewers.
Key Takeaways
- Whole home drain problems usually point to the main sewer line, not a single fixture.
- Old clay and cast iron sewers in Montreal crack, corrode, and attract tree roots.
- We confirm the problem with a camera inspection before recommending replacement.
- Replacement solves chronic backups that repeated snaking cannot fix.
- We often pair replacement with a backwater valve for extra protection.
Signs You May Need Sewer Line Replacement
- Frequent or repeated backups, even after drain cleaning
- Multiple slow drains throughout the house at once
- Sewage odours inside or around your foundation
- Gurgling toilets or drains
- Soggy patches or sinkholes in the yard above the sewer line
How We Diagnose and Replace
We start with a drain camera inspection to see the exact condition and location of the pipe. If the line is cracked, collapsed, or root filled beyond what drain cleaning can fix, we plan a replacement. Where it makes sense, we recommend adding a backwater valve at the same time.
Minimizing Disruption
We plan each job to limit digging and restore your property as cleanly as possible. If you are dealing with an active backup, our sewer backup and emergency plumbing teams can help immediately.
Frequently Asked Questions
How do I know if my sewer line needs replacing, not just cleaning?
If backups keep returning after snaking or hydro jetting, or several drains are slow at once, the pipe itself may be cracked or collapsed. A camera inspection tells us for certain.
What causes sewer lines to fail in Montreal?
Age is the biggest factor. Older clay and cast iron pipes crack and corrode, and tree roots invade the joints.
Do you have to dig up my whole yard?
Not usually. We locate the failed section with a camera and excavate only what is needed, then restore the area carefully.
Should I add a backwater valve during replacement?
It is often a smart time to do it. Adding a backwater valve while the line is already exposed protects you from future backups and may qualify for a City subsidy.
How long does a sewer line replacement take?
It depends on depth, length, and access. After the camera inspection we give you a clear scope and timeline before any work begins.
