Frozen Pipes? What to Do Before the Plumber Arrives

A few calm minutes can limit the damage. If you have no water or suspect a frozen pipe, follow these steps while you wait for help.

Find Your Main Water Shut-Off Valve

Know where your main shut-off valve is before you need it. If the pipe is cracked, it will start to leak as the ice melts — closing the valve limits the flooding until the pipe is repaired.

Open the Cold Tap Closest to the Frozen Section

Turn on the cold tap nearest to the suspected frozen pipe, usually in the basement. Melting ice and water then have somewhere to go, and you will see right away when the flow returns. If only one tap is dry, the freeze is most likely in the pipe serving that fixture; if every tap is dry, it may be where the water service pipe enters your home.

Never Use an Open Flame

Do not use a torch, kerosene or propane heater, charcoal stove or any open flame to thaw a pipe. It is a fire hazard, and heating a pipe too fast can crack it.

Check for Leaks, Then Call a Plumber

Once the water flows again, turn it back on slowly and check the pipe for cracks, bulges and leaks. If you can’t find the frozen section, the pipe is inside a wall, or you see any damage, call POM Plumbing at (905) 625-8777 — we respond 24/7 across Toronto and the GTA.

Why Frozen Pipes Are a Serious Problem

When temperatures plunge, any pipe exposed to uninsulated areas — basements, crawlspaces, garages, or exterior walls — can freeze solid. And when that happens, pressure builds up inside the system. That pressure often leads to a full burst, damaging drywall, flooring, and other structural components.

A proactive frozen pipe service can prevent major disasters. If you notice signs like reduced flow, strange noises, or visible frost on exposed piping, it’s time to act fast.

Where Pipes Freeze Most Often?

In Toronto homes and buildings, freezing usually starts where the heating does not reach:

Pipes running against exterior walls
The point where the water service pipe enters the home through the foundation wall
Basements, crawlspaces, attics and garages
Outdoor taps and hoses left connected
Unheated rooms, stairwells and vacant units
Who Is Responsible: the City or You?

The water service pipe that brings water to your property is owned partly by the City of Toronto and partly by you:

Section of the water service pipe	Owned by	Who to call
From the watermain to the property line	City of Toronto	311 (City service request)
From the property line into the home	Property owner	A licensed plumber — POM Plumbing, (905) 625-8777

If all your taps are dry, the freeze may be on the service pipe. The City will check its side and, if the pipe is frozen on private property, you will be advised to contact a plumber.

Signs That You Need Frozen Pipe Repairs

Before a line completely bursts, there are warning signs you can catch — if you know what to look for. Catching the problem early can reduce the risk of costly repairs and long-term property damage.

Common Indicators to Watch For:

Sign	What it usually means
No water from one tap	The pipe serving that fixture is frozen
No water from any tap	The freeze may be where the service pipe enters the home
Frost or condensation on exposed pipes	The water inside is freezing or already frozen
Bulging or cracked pipe section	Expanding ice has damaged the pipe
Banging or gurgling noises	Ice or trapped air is restricting the flow
Slow drains or unusual drain smells	A drain line may be partly frozen

If any of these sound familiar, don’t wait — search for a frozen pipe repair near me and get professional help from certified experts like POM Plumbing.

Burst Pipe After Thawing? How We Repair the Damage

Ice doesn’t always burst a pipe while it is frozen. Often the crack shows up only as the ice melts and water starts to flow, so a pipe that “thawed fine” can still leak behind a wall or ceiling. If water is coming through, shut off the main valve first, then call us.

Stopping the Water and Containing the Damage

We isolate the damaged section so water can be restored to the rest of the building, and set up a temporary solution when a permanent repair needs parts or access work.

Repairing or Replacing the Damaged Section

Cracks, pinholes and failed joints are sealed or the damaged length of pipe is replaced. In older homes we also check the condition of the rest of the line, because worn or outdated piping is more likely to fail again — including lead pipe replacement and Kitec pipe replacement where those materials are found.

Rerouting and Insulation to Prevent a Repeat

If a pipe keeps freezing, the fix is to change the conditions around it: insulate it, move it away from the cold exterior wall or seal the draft that reaches it. If water has already damaged floors or walls, we can also help with flood restoration after the leak is stopped.

Frozen Pipes in Commercial Buildings

Frozen pipes in commercial buildings can bring operations to a halt — affecting tenants, staff, and critical systems. Whether you manage a high-rise condo, office, retail space, or industrial facility in Toronto, it’s essential to address freezing risks quickly to avoid water damage, insurance claims, and costly downtime.

Common Problem Areas:

Underground or exterior-facing pipes in garages and mechanical rooms
HVAC water lines and fire sprinkler systems
Unheated storage areas, stairwells, or vacant units

When water supply or drainage lines freeze, even a small delay can result in burst pipes and widespread damage.

Our Commercial Frozen Pipe Services:

Thermal inspections to locate vulnerable or frozen sections
Safe, controlled thawing using non-destructive heat systems
Same-day pipe repair or replacement
System insulation and rerouting for long-term protection

Our team understands the urgency and complexity of commercial plumbing systems. We work fast — often outside business hours — to minimize disruption while ensuring compliance with building codes and safety standards.

Frozen Pipe Repair Cost in Toronto

The cost of frozen pipe repair in Toronto can vary depending on several factors, including the location of the pipe, the extent of the freeze, accessibility, and whether the pipe has burst or is simply blocked by ice. On average, homeowners can expect the following:

Scenario	Typical cost	What it usually involves
Minor frozen pipe repair	250–500	Accessible area, no damage
Moderate repair	500–900	Behind walls or under flooring
Major repair	1,000–2,500+	Burst pipe, excavation or long pipe runs
Commercial or multi-unit property	Custom estimate	Complexity and scale of the building

What affects the price:

Location of the pipe and how easy it is to reach
Extent of the freeze and the length of pipe involved
Whether the pipe is only blocked by ice or has burst
Open ceilings and basements versus pipes behind finished walls or under floors

Commercial buildings or multi-unit properties may require a custom estimate due to complexity and scale.

At POM Plumbing, we provide transparent, upfront pricing after a quick on-site assessment. You’ll know the full cost before any work begins, with no hidden fees or unexpected charges.

Frozen Water Pipe Repair and Prevention Tips

While we’re always here to help, preventing the issue is better than fixing it. If you’re concerned about freezing, there are a few basic strategies you can put in place right now to protect your home:

Keep Interior Temperatures Consistent. Don’t let rooms drop below safe thresholds overnight.
Insulate Exposed Piping. Use foam sleeves or wraps on vulnerable areas, especially pipes near exterior walls and in crawlspaces, attics and garages.
Seal Foundation Cracks. Cold drafts can quickly impact nearby systems.
Let Faucets Drip During Deep Freezes. Leaving a cold tap open enough for a pencil-thin stream keeps the water moving.
Disconnect Outdoor Hoses. Unscrew hoses, turn off the outdoor water supply from inside and let the outdoor taps drain before the first freeze.
Know Your Main Shut-Off Valve. Make sure everyone in the home knows where it is and how to close it.
Going Away? Don’t turn the heating off completely. For a long absence, shut off the main water valve and open the taps to drain the lines.
Consider Leak and Low-Temperature Sensors. Smart sensors can alert you to a drop in temperature or a leak before a small problem becomes a flood.

Even with prevention, cold snaps can still cause damage. If that happens, trust the professionals at POM Plumbing for expert frozen water pipe repair that lasts.

Fix Frozen Drain Pipe Without Tearing Up Your Home

Our team knows how to fix frozen drain pipe sections with non-invasive methods that save your walls and floors. Using targeted heating and camera inspection tools, we identify exactly where the freeze has occurred and correct it without unnecessary damage.

FAQ About Frozen Pipe Repair in Toronto

How do I know if my pipe is frozen or just clogged?

Frozen pipes often show reduced or no flow and feel icy cold to the touch. If there’s no blockage, it may still be flowing freely but sluggishly due to ice.
What should I do first if I think a pipe is frozen?

Find your main water shut-off valve so you can close it quickly if the pipe is cracked, then open the cold tap closest to the frozen section. If you can’t find the frozen section or you see a leak, call POM Plumbing at (905) 625-8777.
Can a frozen pipe thaw on its own?

Sometimes — but the risk of it bursting as it thaws is high. Controlled thawing by a pro is always safer.
Do frozen pipes always burst?

No. A frozen pipe can stay intact, but the expanding ice builds pressure that can crack the pipe or split a joint — and the damage often shows only when the ice melts and water starts to flow. That’s why we inspect every thawed section for cracks, pinholes and joint failures before we leave.
How fast can you respond in a frozen pipe emergency?

We offer same-day and emergency service across Toronto. Our team is on standby during cold seasons for exactly this reason.
How much does frozen pipe repair cost in Toronto?

Frozen pipe repair cost varies, but it’s often far cheaper than fixing a burst. As a guide, a minor repair in an accessible area typically costs $250–$500, a repair behind walls or under flooring $500–$900, and a burst pipe with excavation or long pipe runs $1,000–$2,500+. We give you the full cost after a quick on-site assessment, before any work begins.
Who is responsible for a frozen water pipe — the City of Toronto or me?

The City of Toronto owns the water service pipe from the watermain to your property line; you own the part from the property line into your home. If all your taps are dry, the City can check its side through 311 and will advise you to call a plumber if the pipe is frozen on private property. Frozen pipes inside your home are handled by a licensed plumber — call us.
Does home insurance cover frozen or burst pipes?

Coverage depends on your policy and your insurer’s terms, so contact your insurer as soon as it is safe to do so. Take photos of the damage, limit further loss by shutting off the water, and keep your repair invoice for the claim.
Can you fix frozen pipes in old homes?

Absolutely. We have years of experience working with century-old Toronto homes and their unique plumbing layouts.
