Pipe repair and replacement is the targeted fix or full re-run of a leaking, frozen, corroded, or burst residential or commercial water line, drain line, or sewer lateral. Thomas Plumbing handles burst-pipe emergencies, safe frozen-pipe thawing, copper and PEX repiping, and exterior main-line replacement across North Bay, Ontario and a 60-kilometre radius, with Tyler Thomas (Red Seal, licensed since 2010) on every job from diagnosis through clean-up.
What to do right now if a pipe just burst
Five-step burst-pipe checklist
1. Shut off the main water valve at the meter or where the line enters the foundation. In most North Bay homes the valve sits beside the water heater or in a basement utility room.
2. Open the highest and lowest taps in the house to drain pressure from the lines.
3. Move anything valuable off the floor under the leak. Towels and a wet/dry vacuum buy you time.
4. Do not use a torch, blowtorch, or open flame to thaw a frozen section. House-fire risk is real and high.
5. Call (705) 498-3095. Tyler typically responds inside North Bay city limits in 45 to 90 minutes.
Why pipes burst in North Bay (and how Tyler stops it from happening again)
North Bay sits in climate Zone 7B, with January overnight lows that regularly hit minus 30 degrees Celsius and stretches of two-week deep freezes nearly every winter. The conditions that cause a pipe to fail are predictable: an uninsulated copper line on the cold side of an exterior wall, a kitchen sink supply line in a cabinet against a north wall, a hose bib left connected over winter, a crawlspace with no skirting, or a vacant cottage on Lake Nipissing where the heat got turned off below 15 degrees. The water inside freezes and expands, the pipe ruptures, and once the line thaws the leak shows up as a soaking-wet ceiling.
Tyler fixes the immediate leak and then identifies the root cause so the same break does not happen again next January. Common follow-up work after a burst pipe in North Bay includes adding 12 to 25 millimetres of pipe insulation on every exposed run, relocating a line away from an exterior wall cavity, removing and capping a forgotten hose bib supply, or upgrading a long copper run to PEX which tolerates a freeze without splitting as often.

How much does pipe repair cost in North Bay in 2026
Pricing depends on three factors: the type of failure (surface leak vs hidden vs burst), the pipe material (copper, PEX, galvanized, cast iron), and how much finish work needs to come down to get at the leak. The table below shows the typical 2026 range for the most common calls Tyler runs in the North Bay area.
| Repair Type | What's Involved | 2026 Price (CAD) |
|---|---|---|
| Single visible leak (copper or PEX) | Cut, dry, repair, pressure test, cleanup | 285 to 525 |
| Burst pipe with minor drywall removal | Locate, repair, pressure test, dry-out plan | 485 to 850 |
| Frozen pipe thaw (no split) | Safe thawing with heat lamp, leak check | 225 to 395 |
| Hidden in-wall leak detection plus repair | Acoustic/thermal locate, targeted cut, repair | 750 to 1,650 |
| Underground water-line repair | Excavator access, splice, backfill | 1,850 to 4,200 |
| Galvanized to PEX conversion (single run) | Replace failed galvanized line with PEX | 825 to 1,950 |
| Whole-house PEX repipe (bungalow) | All supply lines replaced, drywall patched | 5,800 to 8,500 |
| Whole-house PEX repipe (two-storey) | Multi-floor work, more access points | 8,500 to 12,500 |
Every repair includes a 4-month labour warranty plus the full manufacturer warranty on any parts installed. After-hours and weekend emergency calls add a 75 to 145 dollar surcharge depending on distance from North Bay. For jobs in Mattawa, South River, and Temagami, Tyler quotes the drive-time supplement before he loads the truck.
Hearing water you cannot find?
A hidden in-wall leak gets worse every hour. Tyler arrives with acoustic and thermal locators so the cut is tiny and the repair is fast.

Plenty of homeowners pay for the same repair three times before someone tells them the underlying line is gone. The decision tree is simple. Compare the failure pattern in the table below.
| Signal | Repair Is Right | Replace Is Right |
|---|---|---|
| Pipe material | Copper or PEX in good shape | Galvanized steel (pre-1960) or polybutylene |
| Failure frequency | First leak on that line | Third leak in 18 months on same line |
| Water pressure | Normal across the house | Noticeably weak at upstairs fixtures |
| Visible condition | Pipe looks clean, no green corrosion | Heavy oxidation, scale, or pinholes |
| Best next step | Spot repair, 285 to 850 (CAD) | Run replacement, 825 to 12,500 (CAD) |
Best pipe material for North Bay winters: PEX vs copper
For new installations and full-house repipes, Tyler defaults to PEX (cross-linked polyethylene) in the North Bay climate. PEX flexes when water inside freezes; copper splits. PEX installs faster, costs less in labour, and resists the slow pinhole corrosion that affects copper in homes on certain North Bay water lines. Copper still wins on long-term mechanical robustness in exposed runs and on the short stubs above water heaters where high-temperature performance matters. Tyler quotes whichever material is right for the specific job and explains why on site.
Top warning signs you need pipe work right now in North Bay
- Water pressure has dropped at upstairs fixtures over the last six months (galvanized steel scaling shut).
- You see green or blue-green corrosion on copper joints (chlorine pitting, leak coming).
- A water stain on the ceiling that grows, even slowly, between rain events (interior supply leak, not the roof).
- Your water meter spins when every tap and appliance is off (a hidden supply-side leak).
- A copper line behind a kitchen sink against a north-facing exterior wall (the #1 freeze location in North Bay homes).
- Cracking or popping sounds in the wall during a cold snap (water freezing inside a copper line).
- Three repair calls on the same supply run in under 18 months (the line is done, replace it).
Frozen pipe thawing: the safe way
Tyler thaws an average of 40 to 70 frozen residential pipes a winter in the North Bay area. The safe method, in order: locate the frozen section by feel (it is the coldest spot on the line), shut the main valve, open the closest faucet, then apply gentle heat with a hair dryer, a heat lamp, or warm wet towels. Total thaw time on a typical kitchen supply is 25 to 45 minutes. Never use a propane torch, a heat gun on high, or anything with an open flame. After the thaw, the line gets a pressure test - about a third of "frozen" pipes have already split silently and will leak as soon as pressure returns.
Whole-house repiping: what is actually involved
A full PEX repipe of a North Bay bungalow takes Tyler and a helper two to three working days. The sequence: shut off the main, drain the system, run new PEX manifold and home-run lines through the basement ceiling joists, push up risers to each fixture inside the wall cavity, connect new shut-offs and supply lines at every sink, toilet, tub, and appliance, pressure-test the entire system, restore water, and patch the drywall at each access cut. The old galvanized or failing copper stays in the walls (removing it costs more than it gains) but is fully bypassed and capped at the main. The home gets full water pressure restored, an estimated 25 to 30 year service life on the new supply system, and a clean-up that leaves the house ready to live in.
For diagnostics that pair with this work, see sewer camera inspection (for the drain side when an in-wall leak is suspected on the waste line), drain cleaning (often called the same week as a pipe repair when the homeowner has been ignoring both), and the North Bay service area page for response times and neighbourhoods covered.
