Every winter, thousands of homeowners face the costly nightmare of frozen and burst pipes. According to insurance industry estimates, water damage from burst pipes is one of the most common homeowner insurance claims during cold months, with average repair costs running into the thousands. The good news is that most freeze-related plumbing disasters are entirely preventable with some straightforward preparation before temperatures drop.
Winterizing your plumbing is not just for homes in the far north. Even regions that experience occasional freezing spells can suffer pipe damage, especially in areas of the home that lack adequate insulation such as crawl spaces, attics, garages, and exterior walls. Taking a proactive approach each fall can save you significant money and stress.
The single most effective step you can take is insulating any pipes that are exposed to cold air. Foam pipe insulation sleeves are inexpensive and available at any hardware store. Focus on pipes in unheated spaces like the garage, basement, crawl space, and attic. Pay special attention to pipes running along exterior walls, as these are most vulnerable to freezing.
For pipes in especially cold areas, consider using heat tape or heat cables. These electrically powered wraps maintain a steady temperature along the pipe surface and can be controlled with a thermostat. They are particularly useful for long runs of pipe in crawl spaces or for homes with a history of frozen pipes in specific locations.
Before the first freeze, disconnect all garden hoses from outdoor spigots. Water left in a connected hose can freeze and back up into the pipe inside your wall, causing it to burst. After disconnecting hoses, open the outdoor faucet to let any remaining water drain out. If your home has interior shutoff valves for outdoor faucets, close them and then open the outdoor faucet to drain the line completely.
If you have an irrigation system, have it professionally blown out with compressed air to remove all water from the lines. Sprinkler heads and underground pipes are especially susceptible to freeze damage, and repairs can be expensive come spring.
When temperatures are forecast to drop well below freezing, let a thin stream of water trickle from faucets served by exposed pipes. Moving water is much harder to freeze than standing water. Focus on faucets along exterior walls or in the coldest parts of the house. While a small trickle does use some water, the cost is negligible compared to repairing a burst pipe.
Open cabinet doors under kitchen and bathroom sinks to allow warm air from the room to reach the pipes. This simple step can make a significant difference, especially in older homes where plumbing runs through poorly insulated exterior walls.
Every member of your household should know where the main water shutoff valve is located and how to operate it. If a pipe does burst, shutting off the water supply quickly can be the difference between a minor cleanup and a major renovation. Test your shutoff valve before winter arrives to make sure it turns easily and actually stops the flow of water. Valves that have not been operated in years can seize up or fail to close completely.
Consider labeling the shutoff valve clearly and keeping a wrench nearby if one is needed to turn it. In an emergency, every second counts.
If you are leaving your home unoccupied during winter, keep the thermostat set to at least 55 degrees Fahrenheit. This maintains enough warmth inside the walls to prevent pipes from freezing. Some homeowners also choose to shut off the water supply entirely and drain the system when leaving for extended periods. Smart home water monitors can alert you to temperature drops or unexpected water flow while you are away, providing an extra layer of protection.
Taking these steps each year before cold weather sets in protects your home, your wallet, and your peace of mind. A few hours of preparation is a small price to pay for avoiding the disruption and expense of frozen or burst pipes.
