How to Prevent Frozen Pipes: A Winter Plumbing Guide
Winter in Utah is beautiful. The mountains turn white, the air gets crisp, and everyone breaks out their coziest sweaters. But there's a less charming side to those cold snaps. Freezing temperatures can wreak havoc on your home's plumbing if you're not prepared.
At Right Away Plumbing, we've spent years responding to calls from panicked homeowners staring at a burst pipe and a growing puddle on the floor. We've seen what works, what doesn't, and what tends to catch people off guard.
This guide walks you through how to prevent frozen pipes before winter even hits, plus what to do if you're already dealing with one. Think of it as the plumbing prep talk we wish every homeowner got before their first hard freeze.
Why Frozen Pipes Are Such a Big Deal
Water expands when it freezes. That's just basic science. But inside a pipe, that expansion has nowhere to go. The pressure builds up fast, and something has to give.
Sometimes it's a small crack. Other times it's a full-blown burst pipe that floods a basement in minutes.
Here in Utah, we get the kind of cold snaps that turn a minor plumbing oversight into a major headache overnight. Frozen pipes in Utah are especially common in homes with pipes running through unheated crawl spaces, garages, or exterior walls.
Older homes are often the most vulnerable, since they weren't always built with modern insulation standards in mind.
The good news? Most frozen pipe emergencies are preventable. A little effort now can save you thousands in water damage repairs later.
Which Pipes Are Most at Risk
Not every pipe in your house faces the same risk of freezing. Some spots are natural cold traps. Knowing where to focus your prevention efforts makes the whole process a lot less overwhelming.
Pipes most likely to freeze include:
Pipes running along exterior walls
Plumbing in unheated basements, attics, or crawl spaces
Water lines in garages
Outdoor hose bibs and sprinkler lines
Pipes under sinks that back up to exterior walls
If you walk through your home and can point to a pipe that fits one of these descriptions, that's a good place to start your prevention plan.
How to Keep Pipes From Freezing
Let's get into the practical part. These are the same tips our technicians give customers every fall, and they genuinely work when done consistently.
1. Add Pipe Insulation
This is probably the single most effective step you can take. Pipe insulation is cheap, easy to find at any hardware store, and simple to install yourself. Foam pipe sleeves slide right over exposed pipes and give them a layer of protection against the cold.
Focus your insulating water pipes efforts on the areas we mentioned above: crawl spaces, garages, attics, and exterior walls. For pipes in extremely cold areas, you can also use heat tape, which gently warms the pipe from the outside.
2. Seal Up Drafts
Cold air sneaking in through small gaps and cracks is often the real culprit behind frozen pipes. Walk around your foundation and check for gaps near where pipes enter your home. Caulk or spray foam can seal these spots quickly.
Don't forget about dryer vents, cable lines, and other openings. Even small gaps let in enough cold air to freeze a nearby pipe over a long night.
3. Keep a Steady Temperature Indoors
It might feel wasteful to keep your thermostat at the same temperature day and night, but it's one of the easiest ways to prevent pipes from freezing.
Try not to let your home drop below 55 degrees, even when you're away for the weekend or heading out of town for the holidays.
If you're traveling during a cold spell, ask a neighbor or family member to check on your house. A quick peek can catch a problem before it turns into a disaster.
4. Let Faucets Drip
On especially cold nights, let faucets connected to exposed pipes drip slightly. Moving water is much less likely to freeze than water sitting still. This trick costs you a little extra on your water bill, but it's far cheaper than a frozen pipe repair bill.
5. Open Cabinet Doors
If you have pipes running under sinks along exterior walls, open the cabinet doors on cold nights. This lets warm household air circulate around the pipes instead of trapping cold air inside a closed cabinet.
6. Disconnect and Drain Outdoor Hoses
Before the first freeze hits, disconnect garden hoses and drain any water left in outdoor spigots. Shut off the water supply to outdoor faucets if your home has an interior shutoff valve. This simple step prevents a lot of frozen pipe headaches every year.
7. Keep Garage Doors Closed
If your washing machine or water lines run through the garage, keep the garage door closed as much as possible during cold weather. A closed garage stays noticeably warmer than one left open to the elements.
What to Do When Pipes Freeze
Even with the best frozen pipe prevention plan, sometimes a pipe freezes anyway. Here's what to do when pipes freeze so you can handle it calmly and avoid making things worse.
Shut off the main water supply. This reduces pressure and lowers the risk of a burst pipe while you work on thawing things out.
Locate the frozen section. Look for a bulging pipe, frost on the outside, or a faucet that won't produce water.
Apply gentle heat. Use a hair dryer, a space heater placed a safe distance away, or towels soaked in hot water. Never use an open flame, blowtorch, or anything with exposed heat elements near a pipe.
Turn on the faucet. Open the faucet connected to the frozen pipe. This relieves pressure and lets you know when water starts flowing again.
Check for leaks. Once the pipe thaws, inspect it closely. Sometimes the freeze causes small cracks that don't show up until the ice melts and water pressure returns.
If you can't locate the frozen section, or if you notice water pooling anywhere, it's time to call in a professional rather than guessing.
If a Pipe Bursts: What to Do Next
Burst pipes require fast action. Here's your quick checklist:
Shut off the main water valve immediately.
Turn off electricity to the affected area if water is near outlets or appliances.
Open faucets to drain remaining water from the pipes.
Move furniture and belongings away from the water.
Call an emergency plumber right away.
The faster you act, the less damage you'll deal with. Water damage can spread into walls, flooring, and even your foundation if it's left unaddressed for too long.
When to Call a Professional for Frozen Pipe Repair
Some situations call for more than a hair dryer and a little patience. If you're dealing with a pipe you can't access, one hidden behind a wall, or one that's already burst, it's time to call a licensed plumber.
That's where emergency plumbing services come in. A licensed plumber has the tools and training to thaw frozen pipes safely, repair damage, and check for hidden issues you might miss on your own.
Trying to fix a serious frozen pipe repair Utah situation without the right equipment can sometimes cause more damage than it solves.

A Few Myths Worth Clearing Up
There's a lot of advice floating around online about frozen pipes, and not all of it holds up.
Myth: Keeping your heat on high all winter guarantees no frozen pipes. Not true. Even a warm home can have cold pockets in crawl spaces, garages, or exterior walls where heat rarely reaches.
Myth: A frozen pipe will always burst. Not always, but the risk goes up the longer the freeze lasts and the more pressure builds inside the pipe.
Myth: You can thaw a pipe with a blowtorch to save time. Please don't. Open flames near pipes are a serious fire hazard and can damage the pipe material itself.
How to Prevent Frozen Pipes Before the First Freeze
Before the next cold snap rolls in, run through this quick list:
Insulate exposed pipes in crawl spaces, attics, and garages
Seal any drafts near foundation openings
Disconnect and drain outdoor hoses
Know where your main water shutoff valve is located
Keep a consistent indoor temperature
Save your local plumber's number somewhere easy to find
That last one matters more than people expect. In the middle of a plumbing emergency, the last thing you want to do is search for a phone number while water is spreading across your floor.
