Sewer Line Repair in North Bay
Sewer line repair in North Bay is a camera-first service from Poly-B Plumbing, covering sewer laterals and water service lines in North Bay, Callander, Sturgeon Falls, Powassan and the surrounding communities. A sewer lateral is the buried pipe that carries everything from the house to the municipal main or the septic tank, and in North Bay the section from the main to the house is the property owner’s to maintain and replace. Poly-B inspects the line by camera, shows you the break or the roots on video, quotes repair and replacement side by side, arranges Ontario One Call locates and City permits, and restores the yard after. Call 705-345-6616.

Signs the sewer line, not the drain, is the problem
One slow sink is a drain. Several fixtures backing up at once, sewage rising in the basement floor drain or the lowest tub, gurgling toilets when the washing machine drains, a wet or sunken strip of lawn in dry weather, or a sewer smell outside the house: those point to the lateral. A camera inspection settles it in under an hour and Poly-B Plumbing does one before quoting any sewer work in North Bay, because a cable can open a root-choked line for a week and tell you nothing about why it clogged.
Who is responsible for the sewer line in North Bay?
The City of North Bay maintains the sewer main in the street. The service connection from the main to the house is installed and maintained at the property owner’s expense under the City’s sewer by-laws, and that includes the section under the boulevard and the sidewalk. The same split applies to the water service: the City owns the main and the curb stop; the owner owns the line from there into the house. Poly-B checks the address against the City’s records and tells you which side of the line the problem is on before any quote is written.
What Poly-B repairs and replaces underground
| Problem | What the camera shows | Fix Poly-B quotes |
|---|---|---|
| Tree roots | Roots entering at clay pipe joints, usually every metre | Root cutting and jetting for now; spot repair or replacement of the root-bound section for good |
| Offset or separated joint | A step in the pipe where frost heave or settling moved one section | Excavate and replace that section in SDR 35 PVC with proper bedding |
| Belly (sag) holding water | Standing water on camera where the pipe lost its slope | Re-lay the bellied run to the OBC minimum grade |
| Cracked or collapsed pipe | Broken wall, soil visible, camera cannot pass | Replace the failed run; sometimes the whole lateral |
| Failed cast iron under the slab | Scale, holes, channelling along the bottom | Replace under-slab sections in PVC; add a cleanout |
| Leaking or corroded water service | Meter moving with the house valve closed; wet lawn | New copper or PEX service from the curb stop to the meter |
| Old polybutylene or galvanized service line | Low pressure, rust, repeat leaks | Replacement in copper or PEX |
Poly-B uses code-approved materials only: SDR 35 PVC for sewer laterals, Type K copper or PEX for water services. On lining and pipe-bursting products, Poly-B is direct: they suit some lines and not others, and a lining will not fix a belly or a collapsed section. You get the honest answer for your pipe, not a sales pitch for a method.
Why sewer lines fail around North Bay
Frost is the first cause. The City of North Bay Engineering Design Guidelines (March 2021) require 1.8 m of cover on buried services for frost protection, and services under 1.0 m are not permitted at all. Laterals installed decades ago near the foundation were often shallower than that, and each winter’s heave shifts the joints a little until one opens. The second cause is age and material: clay and early cast iron laterals in North Bay’s older neighbourhoods are past their design life, and the trees planted along those streets in the same era have had sixty years to find the joints. The third is slope. Ontario Building Code 7.4.8 requires drainage pipe of 3 inches or less to fall at least 1 in 50, and a lateral that settled into a belly holds water and solids until it blocks.
Repair or replace the whole line?
| Spot repair | Full replacement | |
|---|---|---|
| Makes sense when | One break, one offset joint, or roots at one spot in an otherwise sound pipe | Clay or cast iron with roots at every joint, multiple breaks, a long belly, or a collapse |
| Time | Usually one day | One to two days, depending on length and depth |
| What you get | New section, camera-verified, yard restored | New lateral to the property line in PVC, new cleanout, warranty |
| Risk | The next joint over may be the next call | Higher cost once; no more sewer calls on that line |
You get both quotes with the camera footage, pros, cons and timelines explained, and the choice is yours.
What sewer line repair costs in North Bay
Poly-B Plumbing quotes sewer and water line work flat-rate, in writing, after the camera inspection. The price moves on:
- Depth and length. A lateral at 2 m under a lawn is a different dig from one at 3 m under a paved driveway.
- What is on top of it. Lawn is restored by regrading and seeding; interlock, asphalt or a deck add restoration cost.
- Spot repair versus full replacement. See the table above.
- Permits and locates. Ontario One Call locates are free but take up to five business days; City permits are included in the quote.
Members of the $49-per-month plan get priority booking and discounts. Emergency backups are taken during business hours.
Locates, permits and licensing
Digging in Ontario without a locate is illegal under the Ontario Underground Infrastructure Notification System Act, 2012. Poly-B requests the Ontario One Call locate, waits the required period, and marks the dig before the excavator arrives. Sewer connection work in North Bay is permitted through the City, and Poly-B handles that paperwork. Plumber (306A) is a compulsory trade regulated by Skilled Trades Ontario, so the person connecting your lateral must be certified or a registered apprentice. Poly-B’s owner holds Red Seal journeyman certification, is licensed for plumbing, wells, septic and backflow prevention, and carries up to $5 million in liability insurance.

Where Poly-B repairs sewer and water lines
Sewer line questions from North Bay homeowners
Do I need a full replacement if the line has one leak?
Not always. Poly-B Plumbing inspects the line by camera and recommends a spot repair when the rest of the pipe is sound. Full replacement is the better call when the pipe is clay or cast iron with roots at every joint, or has more than one break.
How long will my yard be dug up?
Spot repairs usually take one day. Full replacements take one to two days. Poly-B Plumbing backfills, regrades and restores the excavation before leaving.
Can Poly-B do trenchless sewer replacement?
Poly-B Plumbing assesses your line on camera and tells you whether a lining or pipe-bursting method suits it. Bellies and collapsed sections cannot be lined, and Poly-B says so rather than selling a method that will not hold.
Does Poly-B pull permits and locates?
Yes. Poly-B Plumbing requests Ontario One Call locates, which are required by law before any digging in Ontario, and handles City of North Bay permits for sewer and water service work.
Who pays for the sewer line under the sidewalk in North Bay?
The property owner. In North Bay the service connection from the municipal main to the house is installed and maintained at the owner’s expense, including the portion under the boulevard. The City is responsible for the main itself.
