When the temperature drops, one of the last things you want to worry about is frozen pipes. Unfortunately, it’s something that happens all too often when the cold weather hits hard. The problem is that water in your pipes can freeze, causing a lot of damage if left unchecked. 

Whether it’s a minor inconvenience or a major emergency, knowing what to do when your pipes freeze can save you a lot of stress and money. At WM Buffington, we've been providing expert plumbing services in Harrisburg and the surrounding area for decades, and we’re here to help you handle cold-weather plumbing issues and prevent them from happening in the first place.

Why Do Pipes Freeze?

Frozen pipes are a common problem that many individuals and businesses in Pennsylvania can face, especially during harsh winters. The main culprit that underlies every frozen pipe is the combination of cold temperatures and poor insulation. This isn’t simply an inconvenience, however. It’s important to know that when the temperature drops, the water inside your pipes can freeze and expand. This expansion creates strong outward pressure, which can cause the pipe to crack or even burst, leading to costly water and structural damage.

Pipes that are most vulnerable are those in unheated spaces like basements, attics, or crawl spaces. If your pipes run along exterior walls or in areas with drafts, they’re at even higher risk. Even a small crack in the pipe can lead to major problems once the water begins to thaw and flow again. Keeping these pipes properly insulated is key to avoiding a frozen pipe disaster.

Signs Your Pipes Are Frozen

It’s not always obvious when your pipes have frozen, but there are a few signs you can look out for. One of the most obvious indicators is when you turn on a faucet, and only a trickle of water, or none at all, comes out. If you notice this happening, it could mean that the pipe leading to that faucet has frozen. Another sign is visible frost on your exposed pipes. If you see frost or any bulging sections on your pipes, that’s a good indication that the water inside has frozen.

Unusual smells or sounds when turning on a faucet can also signal a frozen pipe. The water trying to push through an ice block inside the pipe may make odd noises or produce strange smells. Additionally, if the walls near your pipes feel noticeably colder than usual, it could mean that there’s frozen water behind the wall. Lastly, if you hear banging or clanking noises from your pipes, it could be a sign of expanding and contracting frozen water.

If any of these symptoms sound familiar, it's time to act quickly before the problem escalates into a burst pipe or flooding.

What to Do Immediately If Your Pipes Freeze

If you suspect your pipes have frozen, don’t panic. The quicker you act, the less damage you’ll face. Here’s what to do right away:

1. Turn Off the Water Supply: First, find your main water shutoff valve and turn it off. This will prevent any water from flooding your home if the pipe bursts. 
2. Open Faucets: Open the faucets connected to the frozen pipes. This allows water to flow once the ice begins to melt and relieves any pressure that may be building up, which can prevent the pipe from bursting.
3. Apply Heat to the Frozen Section: Gently warm up the frozen pipe with a hairdryer, space heater, or heat tape. Never use an open flame like a blowtorch, as this can damage the pipe and start a fire.
4. Keep the Area Well-Ventilated: If the frozen pipe is in an uninsulated area like a basement, attic, or crawl space, try to increase airflow. Open doors to the area and turn on any fans to help the thawing process.
5. Call a Professional: If you can’t locate the frozen pipe or can’t thaw it safely, it’s time to call a plumber. They have the tools and expertise to handle the situation without causing further damage.

How to Prevent Your Pipes From Freezing

The best way to deal with frozen pipes is to avoid them altogether. While some things are beyond your control, there are several steps you can take to protect your pipes before the cold weather hits.

• Insulate Vulnerable Pipes: Use foam insulation or pipe sleeves on pipes located in unheated areas like basements, crawl spaces, and attics. Insulating these areas helps keep temperatures consistent and prevents freezing.
• Seal Gaps and Cracks: Check for drafts around windows, doors, and walls, especially near plumbing. Seal up any gaps with caulk or weather stripping to keep cold air out.
• Let Faucets Drip: If you know temperatures are going to dip, leave faucets connected to exposed pipes running at a very slow drip. This keeps water moving through the pipes, reducing the chance of freezing.
• Keep the Heat On: If you’re leaving for an extended period, make sure your thermostat is set to at least 55°F (13°C) to keep pipes from freezing.
• Open Cabinet Doors: If pipes are located under sinks, especially in exterior walls, open cabinet doors to allow warmer air to circulate around the pipes.
