Frozen Pipe Thawing & Repair in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
A frozen pipe is on a clock. The water expanding inside the line is what cracks it, and most freeze-related bursts happen during or right after thawing. Tornado Plumbing & Drains thaws frozen lines safely across Toronto and the GTA, repairs any burst section, and recommends specific insulation or relocation work for lines that are likely to freeze again next winter.

When this page makes sense
A good place to start for active leaks, burst pipes, sewage backups, or no-water issues where fast stabilization matters.
Most common signs
- Supply lines in exterior walls.
- Outdoor hose bibs without frost-free design.
- Lines in unheated garages, attics, or crawlspaces.
- Basement supply runs near foundation cracks or vents.
What the visit usually includes
- 1. Locate the freeze: Trace the line and find where the ice plug is.
- 2. Open a faucet downstream: Give expanding water a path out as the line thaws.
- 3. Apply controlled heat: Use a heat gun, heat tape, or warm-water blanket — never an open flame.
What changes price and scope
- How active the failure is and whether emergency stabilization is needed before the actual repair.
- Access difficulty around shut-offs, finished ceilings, walls, or tenant-occupied spaces.
- Whether the visit stays within one repair or uncovers follow-up work on damaged fittings, valves, or piping.
How a professional visit usually unfolds
1. Locate the freeze
Trace the line and find where the ice plug is. Thawing the wrong section wastes time.
2. Open a faucet downstream
Give expanding water a path out as the line thaws. Reduces pressure that could split the pipe.
3. Apply controlled heat
Use a heat gun, heat tape, or warm-water blanket — never an open flame. Safe thawing without damaging the pipe or surrounding finishes.
4. Pressure / leak check
Watch the line as it thaws and pressure-test once flow is restored. Catches a hidden burst before walls close up.
5. Prevent the next freeze
Insulate, reroute, or replace freeze-prone lines as needed. Stops next winter's emergency from being the same call.

25-year workmanship warranty
Every job Tornado Plumbing & Drains completes in Toronto and the GTA — repair, install, replacement, drain work, sewer work, fixture work — is backed by a 25-year workmanship warranty.

Call now if:
- A faucet or fixture has stopped flowing during cold weather.
- Pipes in an unheated basement, garage, or crawlspace are cold to the touch and not flowing.
- Frost is visible on a supply pipe.
- A line was frozen and now you see leaking as it thaws.
- An exterior hose bib has frozen and is leaking inside the wall.
- The home was unoccupied during a deep freeze.
Common freeze-prone locations
- Supply lines in exterior walls.
- Outdoor hose bibs without frost-free design.
- Lines in unheated garages, attics, or crawlspaces.
- Basement supply runs near foundation cracks or vents.
- Vacant rentals or seasonal properties with low heat.
- Pipes that recently froze and are likely to freeze again.
Frozen pipe service cost: what affects the quote
Pricing depends on whether the line can be reached easily, whether thawing is enough or the pipe also burst, and whether prevention work is part of the visit. A single accessible freeze on copper that thaws cleanly stays in the lower range. A burst inside a wall after thaw, or multiple frozen runs, pushes higher.
When thawing is only step one
If the line bursts during thaw, the repair becomes a burst pipe job. If a line freezes every winter, thawing it again next year is the wrong fix — the right answer is insulation, rerouting, or replacing the run with one that does not sit in an unheated space. For homes that go unoccupied in winter, the conversation usually includes shut-off and drain-down planning.
What to share when you call
- Which fixture stopped flowing.
- How cold it has been and where the home stayed coldest.
- Whether you can hear water dripping in a wall (sign of a burst).
- Pipe material and approximate location if known.
- Whether the home was unoccupied during the freeze.
- Photos of frosted pipe, leak, or affected area.
Prevent the next freeze
Keep heat above 13°C in unoccupied homes during winter. Drain exterior hose bibs before the first freeze. Insulate supply lines in unheated spaces. Open cabinet doors under sinks on exterior walls during cold snaps. Replace standard hose bibs with frost-free models on freeze-prone exterior lines.
Toronto context
Frozen pipes in Toronto concentrate in three locations — exterior wall supply lines (kitchen sinks on outside walls, second-floor bathrooms above an unheated garage), rim joist runs in older basements with poor air seal, and outdoor hose bibs that weren't shut off in fall. Safe thawing is heat blanket, controlled steam, or directed warm-air — not open flame.
What to confirm before approving frozen pipe work
- The technician should pressure-test after thaw to catch hidden bursts.
- Freeze-prone lines should be insulated or rerouted, not just thawed and left.
- Quotes should separate thawing, repair, and prevention work.
Useful info on the call: which fixture stopped flowing, where the home is coldest, and whether you have heard dripping in a wall.
Frequently asked questions
Can I thaw a frozen pipe myself?
Hair dryers and warm towels on accessible lines can work. Never use an open flame. If the pipe is inside a wall, in a crawlspace, or you suspect it has already burst, call before you turn the water back on.
How do I know if a frozen pipe has burst?
If you hear water dripping in a wall, see a stain spreading, or notice low pressure once the line thaws, the pipe likely burst. Shut off the water and call right away.
Why does the same pipe keep freezing every winter?
Lines that freeze repeatedly are usually in exterior walls, unheated spaces, or near vents. Insulation alone may not be enough; sometimes the line needs to be rerouted to a heated chase.
How can I prepare an unoccupied home for winter?
Maintain a minimum heat setting, shut off and drain exterior lines, and consider draining the system if the property will be empty for an extended period in deep cold.

Pipe frozen with no water flow? Don't use a torch — call.
Open the affected tap, locate your main shutoff in case the pipe has already split, and call 647-784-8448. Open flame on a frozen pipe is a fire and burst risk. Tornado uses heat blankets, controlled steam, and thermal imaging to thaw safely. Same-day across Toronto and the GTA.
