Renovation Plumbing in North Bay
Renovation plumbing in North Bay is a licensed service from Poly-B Plumbing for kitchen, bathroom and basement renovations in North Bay, Callander, Sturgeon Falls, Powassan and the surrounding communities. Renovation plumbing is the rerouting of supply and drain lines, relocation of toilets, showers and sinks, new rough-ins, valve and shut-off upgrades and fixture installation that a renovation needs behind the finishes, done to Ontario Building Code so it passes inspection the first time. Poly-B works with your contractor or directly with you, quotes flat or in phases, and uses no push-fit or temporary fittings. Call 705-345-6616.

What the plumbing side of a renovation involves
| Project | Plumbing work behind it | Permit and inspection |
|---|---|---|
| Bathroom renovation, same layout | New shut-offs, new supply lines to the vanity and toilet, shower valve replaced, drain checked and re-sealed | Usually no permit when fixtures stay put; Poly-B confirms with the City |
| Bathroom layout flip, or a shower where the tub was | Drain relocated and re-vented, supply rerouted, floor opened for the new trap | Plumbing permit and rough-in inspection before the floor closes |
| Kitchen renovation | Sink and dishwasher relocation, garburator, pot filler, fridge water line, drain re-vented if the island moves the sink | Permit where drains move; island sinks need a loop or air-admittance vent |
| Basement bathroom or wet bar | Underground drain, sewage ejector if below the building drain, supply from the main, backwater valve if fixtures are below the manhole cover | Underground inspection before concrete, then rough-in and final |
| Laundry room addition or move | Hot and cold with hammer arrestors, standpipe and trap, floor drain | Permit where the drain is new |
| Legal suite or second unit | Full rough-in for a kitchen and bathroom, separate shut-offs, often a second water heater | Full permit set with the building permit |

Plumbing for a bathroom renovation in North Bay
The bathroom is the renovation Poly-B Plumbing sees most, and the plumbing decisions come before the tile. Keep the toilet where it is if you can; moving a toilet means moving a 3-inch drain and its vent, which is the single most expensive change in a bathroom. A shower replacing a tub needs a new trap location and, in many North Bay homes, a check that the drain actually falls the required 1 in 50 to the stack. A double vanity needs the drain re-vented, not just tee’d. Replace the shut-offs while the wall is open; original valves in a 1970s house will not close when you need them to. And if the house has polybutylene or galvanized supply anywhere, the renovation is the cheapest moment to replace the run that feeds the new bathroom, because the wall is already open.
What renovations uncover in older North Bay homes
- Galvanized stubs and original shut-offs feeding new fixtures, shedding rust into the new faucet within a year.
- Cast iron stacks channelled along the bottom, sometimes holed, behind a wall that is about to be tiled.
- Unvented or S-trapped fixtures from a previous “handyman” renovation, which is why the old sink gurgled.
- Drains laid flat or uphill, which no amount of drain cleaning fixed.
- Polybutylene in homes from the 1980s and 1990s, and the Poly-B name on the truck is a coincidence: Poly-B Plumbing replaces polybutylene pipe rather than connecting new fixtures to it.
- Supply lines in exterior walls that have frozen before and will again. The renovation is the time to reroute them.
Poly-B fixes what it finds, tells you before it does, and prices it as a change rather than a surprise on the invoice.
What renovation plumbing costs in North Bay
Poly-B Plumbing quotes renovation work flat-rate for a defined scope, or in phases when the plan is still moving. Estimates can be given from plans or a walkthrough; final quotes come once the layout is confirmed. The price depends on:
- Whether drains move. Supply lines are cheap to reroute; drains and vents are not.
- What is behind the wall. Sound copper is connected to; galvanized or polybutylene is replaced.
- Below-grade work. An ejector pit, a sump or a backwater valve in a basement renovation.
- Fixture choices. Wall-hung toilets, freestanding tubs and rain heads each have a plumbing cost beyond the fixture itself.
Members of the $49-per-month plan get priority booking and 10 percent off eligible renovation work.
Working with your contractor
Poly-B Plumbing is used to open walls, tight timelines and plans that change on Tuesday. The rough-in date is held, the inspection is scheduled so the drywaller is not waiting, and the finish visit is booked once the tile is grouted. Pipework is neat, shut-offs are labelled, and the site is left clean for the next trade. If you are managing the renovation yourself, Poly-B handles the plumbing permit directly and tells you which inspections have to happen before which stage.
Why licensed plumbing matters in a renovation
Plumber (306A) is a compulsory trade in Ontario regulated by Skilled Trades Ontario. Moving a drain, re-venting a fixture or connecting a water heater is certified work, and an inspector will ask who did it. Poly-B’s owner is a second-generation Red Seal journeyman plumber in the trade since 2003, licensed for plumbing, wells, septic and backflow prevention, with up to $5 million in liability insurance. Poly-B regularly fixes what unlicensed renovation crews left behind; it costs less to have it done once.

How Poly-B runs a renovation
Plan and estimate
From plans or a walkthrough, with layout advice that avoids framing, venting and flow problems.
Permit
Pulled by Poly-B or coordinated with your contractor, with the inspection sequence set out.
Rough-in
Drains, vents and supply installed and tested while the walls are open; anything found behind them reported before it is covered.
Inspection
Scheduled and attended so the schedule holds.
Finish
Fixtures set and tested after tile and paint, shut-offs labelled, walkthrough done.
Basement renovations and legal suites
A basement bathroom, kitchenette or full secondary suite is the renovation with the most plumbing below the floor. Fixtures that sit below the building drain need a sewage ejector pit and pump, which Poly-B plans in the underground stage so the concrete is cut once. Where fixtures are below the upstream manhole cover, the Ontario Building Code calls for a backwater valve, and a suite usually wants its own shut-offs and often a second water heater. Poly-B lays all of that out on the plan, prices it in one scope, and coordinates the underground inspection before the floor is poured.

Where Poly-B does renovation plumbing
Renovation plumbing questions from North Bay homeowners
Do I need a permit for plumbing work during a renovation?
Yes, wherever drains or vents are added or moved, and often for supply changes. Poly-B Plumbing obtains the permit or coordinates it with your contractor and sets out which inspections happen before which stage.
Can Poly-B work with my contractor or designer?
Yes. Poly-B Plumbing works as part of the renovation team, holds the rough-in date and schedules inspections so other trades are not waiting.
Can Poly-B help plan fixture locations?
Yes. Poly-B Plumbing advises on layouts that avoid problems with framing, venting and flow, and tells you when moving a toilet will cost more than the rest of the bathroom plumbing combined.
Can I get a quote before the walls are open?
An estimate, yes, from plans or a walkthrough. The final quote follows once the layout is confirmed and Poly-B Plumbing has seen what is behind the wall.
Should I replace old pipes during a renovation?
If the run that feeds the new room is galvanized, polybutylene or pitted copper, yes, while the wall is open. Poly-B Plumbing prices it as an option so you can decide.
