Why Pipes Burst During Cold Weather
When temperatures drop below freezing, the water inside your pipes can freeze and expand. Since water expands as it turns to ice, it puts a lot of pressure on the inside of the pipe. Eventually, the pressure can become too much, causing the pipe to crack or burst. Once the ice thaws, water starts to flow again, only this time, it spills through the broken pipe and into your home.
Pipes that run through unheated areas like attics, basements, garages, and crawl spaces are the most vulnerable. Outdoor hose bibs and pipes that run along exterior walls are also at high risk. Even a small burst can release gallons of water in a matter of minutes, leading to major water damage. Cold weather is one of the largest reasons why plumbing companies experience surges in phone calls and business during the winter months.
This type of damage is common in winter, and it can happen without warning. That’s why knowing how to prevent pipe bursts and preparing your home before a cold snap is so important.
Tips to Prevent Frozen and Burst Pipes
One of the most effective ways to prevent pipe bursts is to insulate your pipes. Pipe insulation is inexpensive and easy to install. Focus on exposed pipes in unheated areas and along exterior walls. You can find foam sleeves or wrap-style insulation at most hardware stores.
During extremely cold weather, keep a small trickle of water flowing from faucets served by exposed pipes. Running water is less likely to freeze, even if it’s just a slow drip. This can reduce pressure inside the pipes and prevent them from freezing solid.
Also, keep your home warm. Don’t let indoor temperatures fall below 55 degrees Fahrenheit, even if you are leaving for vacation. Open cabinet doors under sinks to allow warm air to circulate around plumbing, especially in kitchens and bathrooms along outside walls.
Finally, disconnect and drain outdoor hoses and shut off water to outdoor spigots before winter begins. Use insulated covers to protect them from freezing temperatures.
What to Do If a Pipe Bursts
If a pipe bursts, you must act fast to minimize damage. The first step is to shut off the main water supply to your home. This stops the flow of water and helps prevent further flooding. Once the water is off, open all faucets to drain any remaining water and relieve pressure inside the pipes.
Next, clean up as much standing water as you can using towels, buckets, or a wet vacuum. Move furniture and valuables away from the wet area. Then, contact a licensed plumber to repair the broken pipe and assess your plumbing system for any other vulnerabilities.
After the immediate repair, call a professional water damage restoration company. These experts will inspect the affected area for moisture inside walls, under flooring, and behind cabinets. They use industrial drying equipment to fully remove moisture and prevent mold from growing. If materials are damaged, they can be safely removed and replaced as part of the restoration process.
Burst Pipes Can Create Thousands in Property Damage
A burst pipe can cause thousands of dollars in damage in just a short time. During winter, it’s important to take simple steps to prevent your pipes from freezing and bursting. Insulating your plumbing, keeping your home warm, and letting water drip during cold nights can go a long way in protecting your property.
If a pipe does burst, fast action is key. Shutting off the water, cleaning up the mess, and calling in professionals to handle repairs and drying will help limit the damage. Most importantly, bringing in a certified restoration company ensures your home is properly dried, cleaned, and protected against future problems like mold and structural damage. Preparing for winter now can save you from big headaches later.
