Winter can be tough on your plumbing system. Freezing temperatures, expanding ice, and increased water usage all put extra pressure on pipes, potentially leading to water leaks and costly damage. But the good news is that with just a little preparation, you can protect your home and prevent leaks before they happen.
Here’s our expert guide to preventing water leaks during the colder months—and saving yourself the hassle of expensive repairs.
Why Are Water Leaks More Common in Winter?
Water leaks during the winter are often caused by freezing temperatures. When water freezes inside your pipes, it expands, putting intense pressure on the pipe walls. That pressure can cause cracks or bursts, bringing leaks once the ice thaws.
Additionally, winter storms can lead to flooding and excess water near your home’s foundation, increasing the risk of leaks if your home isn’t properly sealed.
The best approach? Proactive protection!
Steps to Prevent Winter Water Leaks
1. Insulate Your Pipes
Cold pipes mean frozen water. Insulating your exposed pipes is one of the simplest and most effective ways to prevent freezing.
- Focus on areas prone to freezing, like basements, attics, garages, or any outdoor pipes.
- Use foam pipe insulation or heat tape—these affordable solutions go a long way toward saving you from costly repairs.
- Don’t overlook outdoor faucets or hose bibs. Disconnect hoses and attach insulated covers.
2. Keep Your Home Warm
Maintaining a consistent temperature inside your home helps prevent pipes from freezing.
- Keep your thermostat set to at least 55°F, even if you’re away.
- Open cabinet doors under sinks to allow warm air to circulate around your plumbing.
3. Seal Drafty Cracks and Gaps
Cold air seeping into your home can quickly chill pipes. Check for drafts in areas where plumbing runs against exterior walls.
- Seal any cracks, holes, or gaps with caulk or weatherstripping.
- If your home’s foundation allows water to pool, ensure proper drainage systems are in place to direct water away.
4. Keep Your Faucets Dripping
If temperatures are expected to drop, leaving faucets dripping slightly can prevent water from freezing inside pipes.
- Constant water movement makes freezing less likely. Focus on faucets far from your water source, as these areas are often more susceptible to freezing.
5. Inspect for Early Signs of Problems
Regular inspections can help you catch small issues before they become big headaches.
- Check for any visible cracks or deterioration on pipes and seals.
- Look for unusual odors or damp spots near walls, ceilings, or floors—these are often the first signs of hidden leaks.
6. Maintain Your Water Heater
During winter, your water heater works overtime. To ensure it’s functioning well—and not at risk of leaks—take a few precautions.
- Flush your water heater to remove sediment buildup.
- Have your appliance professionally serviced if it hasn’t been checked in over a year.
7. Shut Off Outdoor Water Supply
Don’t forget to turn off your outdoor water supply before winter arrives.
- Drain water from outdoor faucets and sprinkler systems to prevent freezing and expansion.
- If possible, use a shut-off valve to cut water flow entirely to outdoor pipes.
When to Call in the Professionals
While many preventive measures can be handled on your own, sometimes professional intervention is the safest choice.
- Frozen or burst pipes: If ice has already caused damage, call a plumber immediately to minimize water damage.
- Persistent leaks: Don’t ignore leaks you can’t trace—hidden leaks can lead to serious structural issues.
- Water pressure concerns: A sudden drop in water pressure could indicate a leak or other plumbing issue requiring expert attention.
