Frozen pipes are a home or business owner’s worst plumbing nightmare, often requiring an expensive fix. The plumbing repair experts at Lexington, KY’s Plumbing Systems, Inc. have been rescuing customers from frozen pipe disasters since 2005. They say that with proper insulation, you can avoid expensive plumbing emergencies down the road.

Here, they share their top three tips to prepare your system for the harsh cold of winter:

• Insulate For The Climate: In mild climates, an inexpensive foam pipe covering is usually sufficient. For areas with colder weather, you’ll want to invest in a more substantial solution, such as thermostatically-controlled insulation tape. Pay special attention to pipes in unheated areas of the home, as well as pipes that hug any exterior walls. These are at the highest risk of freezing since they’re closest to the elements.
• Find Cracks & Holes: Aside from protecting your pipes from the elements, insulating them will give you time to inspect for other issues that could cause additional problems. Arm yourself with caulk or sealant, and you can patch up any cracks or holes you find in the pipes when you start insulating. This will lower the chance of worse plumbing repair issues down the road.
• Protect Your Walls: This is a first line of defense against freezing that causes pipes to break. Many homeowners could benefit from adding more insulation to the home itself, which will keep room temperatures stable—particularly in areas like attics and crawlspaces, where pipes are most likely to freeze—and help those pipes stay warm. Battling the cold at every step increases your chances of victory against the elements, and your walls are where the fight begins.
