August 1, 2025So, you’ve woken up to an icy morning, turned on the tap and found out that your pipes have frozen. This can lead to major water damage, costly repairs, and even health hazards.
But with the right know-how and a little bit of prep, you can prevent frozen pipes altogether or handle the situation if it’s already happened.
We’ll walk you through the warning signs, prevention tips, and when to call in a plumbing maintenance service to save the day. Let’s dive in!
Why Should You Be Concerned About Frozen Pipes?
As mentioned briefly earlier, ignoring frozen pipes can lead to serious consequences that go far beyond a minor inconvenience.
If you’re not paying attention, you could be setting yourself up for water damage, expensive repairs, or even health risks caused by mould or mildew from burst pipes.
The biggest issue with frozen pipes is that water expands as it freezes, creating intense pressure inside the pipes.
That pressure can cause them to crack or burst, especially around plumbing fixtures where the material might be weaker.
In addition, when the ice starts to melt, all that backed-up water comes gushing out. It’s no longer going to be leak-fix, but it could mean replacing floors, walls, and sometimes even entire plumbing lines!
What Should You Do If Your Pipes Freeze?
There are some clear steps you can take to get ahead of the problem before it turns into a full-on plumbing disaster.
For starters, make sure you keep the faucet open. As you begin to thaw the pipe, water will start to flow, and that moving water will help melt more of the ice.
Now, you might be wondering, should you just wait for your pipes to thaw naturally? In some cases, that might work, but it’s not ideal.
If the pipe bursts while you’re waiting, you’ll have a much bigger mess to deal with. Instead, let’s go step-by-step on how to take control of the situation:
1. Locate the frozen area
Start by checking the most common trouble spots. You can check exterior walls, unheated basements, crawl spaces, or under kitchen sinks. If you see frost on the pipe or feel it’s extremely cold to the touch, that’s likely your culprit.
2. Apply heat safely
You can use a hairdryer, heat lamp, or even towels soaked in hot water to slowly warm the pipe.
Never use an open flame or anything too aggressive as this can damage the pipe or cause a fire hazard. Be patient and work your way along the pipe toward the tap.
3. Check for leaks
Once the water starts flowing again, inspect the area closely. If you spot dripping or moisture along the pipe, that’s a sign of a crack.
Turn off the water supply immediately and call a plumber before things get worse.
4. Can’t find the frozen spot or don’t feel comfortable thawing it yourself?
That’s totally okay! It’s better to call a pro than to risk damage. Acting quickly can save you from hundreds or even thousands in repair costs.
What Can You Do to Prevent Your Pipes from Freezing?
Wouldn’t it be great to avoid the frozen pipe drama altogether?
Luckily, there are a bunch of smart, simple steps you can take to prevent it from happening again.
Let’s walk through what you can do right now to reduce your risk.
1. Insulate exposed pipes.
Pipes in unheated areas like basements, crawl spaces, attics, and garages are most vulnerable.
Wrap them with foam pipe insulation (available at most hardware stores) or use heat tape for an extra layer of protection. It’s a small investment that can save you from major repair bills later.
2. Keep the Heat On
If you’re leaving the house for a winter getaway, set your thermostat no lower than 13°C (around 55°F).
This keeps your home warm enough to prevent pipes from freezing even when you’re not around to notice a problem brewing.
3. Open Cabinet Doors
Especially in kitchens and bathrooms, opening cabinet doors lets warm air circulate around plumbing under sinks. These can be the most common areas for frozen pipes to form.
4. Let Faucets Drip during Cold Snaps
This keeps water moving, and moving water is much harder to freeze. It doesn’t need to be a heavy stream, just a slow, steady drip will do.
5. Seal up Drafts
Check around windows, doors, and anywhere pipes enter your home. Use caulk or weatherstripping to seal gaps that let cold air in. This protects your plumbing and makes your home more energy efficient.
FAQ about Frozen Pipes
Below, we’ve rounded up answers to some of the most frequently asked questions to help you stay one step ahead.
Should you turn off main water if pipes are frozen?
If you suspect your pipes are frozen, it’s a smart move to shut off the main water supply.
This prevents additional water from entering the pipes and reduces the risk of a major leak if one of the frozen sections bursts.
After turning it off, open faucets to relieve pressure and call a professional if you’re unsure what to do next.
Will pouring hot water down drain unfreeze pipes?
It might help, but only if the frozen section is close to the drain and not deep in the wall or underground.
Pouring hot but not boiling water down the drain can help pipes to thaw naturally, especially if the blockage is minor. Just be careful as sudden temperature changes can cause some materials to crack.
If you’re unsure, it’s best to use safer methods like a space heater or heating pad around the affected area.
Do pipes always burst if frozen?
Frozen pipes don’t automatically mean a burst pipe, but the risk is high.
As ice forms, it expands, and the pressure buildup between the blockage and the closed faucet can cause the pipe to split.
That’s why acting fast is crucial. The longer you wait, the higher the chances of serious damage.
How to find where pipes are frozen?
Look for faucets that produce little to no water flow, and trace the pipe back from there.
Frozen sections often feel significantly colder than others or may even be covered in frost. Pay extra attention to unheated areas like basements, garages, or exterior walls.
Sometimes, you may also hear unusual noises when water is turned on, which is another clue something’s frozen inside.
At what temperature Celsius do pipes usually freeze?
Pipes typically begin to freeze at around 0 degrees Celsius (32 degrees Fahrenheit), depending on wind chill, insulation, and how exposed the pipe is.
However, poorly insulated pipes can freeze even at slightly higher temperatures. That’s why prevention is so important when cold weather is on the way.
Conclusion
From spotting the signs early to taking steps to insulate and heat your pipes, now you know exactly what to do when temperatures drop.
That said, if you’re unsure how to handle a frozen pipe or if something already looks or sounds wrong, it’s best not to take chances. Call in a trusted local expert who knows how to deal with winter plumbing issues fast.
