Trenchless Sewer Line Replacement in Toronto: Pipe Bursting or Full-Length Lining
Toronto & the GTA • Call 647-784-8448
Trenchless replacement gives you a new sewer line without the full excavation. The two practical methods are pipe bursting (pulling a new pipe through while breaking the old one) and full-length CIPP lining (installing a new pipe inside the old one). Tornado Plumbing & Drains plans Toronto-area trenchless replacements around what the camera shows, what the route allows, and what the surface above costs to restore.

Part of Drain & Sewer Services in Toronto & the GTA
Book this service when
Book this when repeated backups return within weeks of cleaning and the camera shows the lateral crushed, offset at several joints, delaminated Orangeburg, or bellied, but the route still allows a no-dig method.
Common signs
- Repeated backups that come back within weeks even after snaking or hydro-jetting the same line
- A camera run that shows the pipe collapsed, crushed, or offset at several joints rather than one spot
- Old clay tile or Orangeburg (tar-paper) pipe that has cracked, gone oval, or delaminated along the run
- A bellied or back-pitched section where water pools and sediment keeps settling, defeating every cleaning
If you're not sure, compare these too
- Trenchless Sewer Line Repair - the no-dig method when the pipe is intact enough to line
- Sewer Line Replacement - when a belly or route problem rules trenchless out

When a sewer line needs replacing, not just patching
Replacement is the call when the pipe has lost integrity along its length: multiple collapsed or offset joints, a back-pitched run that holds standing water, or clay/Orangeburg that has cracked far beyond one bad section. We confirm that from the camera footage first, because a single defect is usually a job for spot sewer line repair instead. The deciding factor is whole-line condition rather than any one symptom — once enough of the lateral is structurally gone, lining or replacing the entire run is the only fix that holds.
Signs your sewer line is past repair
- Repeated backups that come back within weeks even after snaking or hydro-jetting the same line
- A camera run that shows the pipe collapsed, crushed, or offset at several joints rather than one spot
- Old clay tile or Orangeburg (tar-paper) pipe that has cracked, gone oval, or delaminated along the run
- A bellied or back-pitched section where water pools and sediment keeps settling, defeating every cleaning
- Heavy root intrusion at multiple joints that grows back fast because the pipe seams have separated
- Sinkholes, soft spots, or settling in the yard or driveway above the sewer route
- Sewage smell or recurring basement floor-drain backups that point to a failing buried main, not a fixture
- The existing sewer is too deteriorated for lining.
- Multiple defects exist along the run.
What's included
- Camera inspection and locating the full run so we map depth, slope, joints, and the exact failure points before choosing bursting or lining
- Method selection and excavation of only the small launch and receiving pits (or use of existing cleanouts) rather than a full open trench
- The replacement itself: pulling a new HDPE pipe through with a bursting head, or curing a full-length CIPP liner inside the host pipe
- Reconnection of the line at the city main and at the building, plus any cleanout reinstated to code
- City of Toronto plumbing permit and required inspections handled, including locates for gas, hydro, and other buried utilities along the route
- Backfill, compaction, and restoration of the small dig areas, with the work site cleaned up before we leave
- A post-job camera pass to verify flow and grade, plus the written 25-year workmanship warranty on the installation
Trenchless replacement methods
| Method | When it fits | Limitation |
|---|---|---|
| Pipe bursting (HDPE) | Aged or collapsed lateral; relatively straight route | Soil and route must allow displacement; tight bends and obstacles can disqualify. |
| Full-length CIPP lining | Aged but intact pipe; multi-joint root entry; scaled cast iron | Cannot fix bellies; needs structurally sound host. |
| Hybrid (lining + spot replacement) | Mixed condition along the run | Requires careful camera planning. |
Trenchless replacement cost
Pricing depends on length, depth, soil, surface above, method, and whether public-side coordination is part of the scope. Toronto-market trenchless full-length lining for shorter laterals often runs $4,000 to $6,500. Larger pipe bursting projects with deeper or longer runs commonly land $9,000 to $18,000, with per-linear-foot equivalents from roughly $80 to $300 depending on conditions and method.
When open-cut is the right answer
Trenchless does not fit every line. Severe collapse, badly bellied sections, complex bends, or routes through congested utility corridors can make open-cut replacement the more practical, lower-risk choice. Hybrid approaches — open-cut for the worst section, trenchless for the rest — are common in Toronto retrofits.
What to share when you call
- Camera footage and locator readings.
- Pipe material, length, and depth.
- Surfaces above the run.
- Whether public-side replacement is also planned.
- Permit and locate status.
- Photos at both ends of the route.
Toronto context
On a Toronto lot where excavation would mean tearing up a heritage front-yard interlock or a mature 60-year-old maple, trenchless replacement (lining where the camera says it's safe, bursting where it doesn't) keeps the surface intact while the pipe gets replaced. Not every line is a candidate — we tell you on the camera review.
What to confirm before approving trenchless replacement
- Method choice should follow camera evidence, not a default trenchless pitch.
- Public-side coordination should be addressed up front.
- Restoration scope and access-pit locations should be documented.
Useful info on the call: camera footage, pipe condition, route, and surface conditions.
Pipe Bursting
The new line we pull in is a single fused length of HDPE with no joints, sockets, or hubs along the run — the exact spots where clay and cast iron crack, separate, and let roots in. Because the bursting head fractures the old pipe outward and compacts the soil, there is often room to pull in a larger diameter than the original, which is useful on undersized older Toronto laterals. When the host pipe is collapsed or so far gone that lining can't bridge it, bursting gives you new pipe on the same route without trenching the whole yard. If you're weighing this against trenchless sewer replacement generally, bursting is the displacement method specifically for failed pipe.
Frequently asked questions
Is trenchless always faster than open-cut?
Often yes for the work itself. Permits, locates, and access-pit prep still take time. Most residential trenchless projects finish in 1 to 2 days of active work.
Will the new pipe be the same diameter?
Pipe bursting can upsize. Lining stays close to the host diameter but with smoother surface. Capacity is similar to or better than the original.
How long does the new line last?
HDPE bursting and CIPP lining both have design lives of 50+ years when installed correctly.
What about the city-side connection?
Coordination with the city tap and the lateral is part of the scope. Some replacements include the public side; some are private-side only. We confirm both before quoting.
Can I upsize my sewer with pipe bursting?
Yes, often. Pipe bursting can install a slightly larger diameter pipe along the same route, which is useful for capacity upgrades.
Do you replace lead water service with pipe bursting?
Yes, on the private side, often coordinated with the city's public-side replacement program. Confirm timing with the city before scheduling private-side work.

May 2024“I had a cast iron stack in my bsmt with a huge crack that was just about to give out. After obtaining a few quotes I decided to hire Tornado given the positive reviews, fair pricing, and there fast response time. The crew were here within an hour, very professional, worked quickly, and left the space immaculate. I recommend them without hesitation. Thank you Serhiy and crew!”

May 2021“I asked Tornado to come and inspect my main drain as it was constantly backing up and causing the house to smell like sewage. They came quickly and helped me identify the problem: roots inside the old clay pipe. Since the problem was really bad, they schedule the repair the very next day and finish the job without any issues in less than 2 days. During the job excavation, they identified the water supply line being lead (really bad for you) and recommended to do the replacement to 3/4" cooper. They offered me a generous discount since the excavation was already completed, so I took them up on the offer to replace both pipes at once. They completed the job without any issues and within the time previously agreed (less than 2 days), and all while having very little disturbances to our water and drain usage during the work. Overall great job!”

June 2019“We want to finish our basement but in the spring when the snow was melting we discovered several leaks in our basement. Serhiy came out to look at our basement and also offered a free camera drain inspection. He provided a very reasonable quote for the waterproofing and a sump pump and went over all our options. With the camera inspection he discovered roots growing through our drain and we called the city to get it cleaned out (luckily it was in the city portion of the drain line). Serhiy did not pressure us into anything and waited patiently (2 months) for us to get back to him - which I appreciate a lot. I am not a fan of pushy sales people. His crew just completed the job and we are very satisfied with the results. They did a fabulous job and left everything clean and tidy. Thanks again!”
