How to Prevent Frozen Pipes in Calgary Winters

Calgary winters are known for their extreme cold, sudden temperature drops, and heavy snowfalls. One of the most common and costly problems homeowners face during these months is frozen water pipes. When pipes freeze, they can burst and cause extensive water damage, leading to expensive repairs. Here’s a practical guide on how to prevent frozen pipes in Calgary’s harsh winters and keep your plumbing system safe and functional. The first and most effective step is to insulate pipes in unheated areas such as basements, attics, crawl spaces, garages, and exterior walls. Use foam pipe insulation sleeves, fiberglass wrap, or heat tape to protect vulnerable pipes from freezing temperatures. Cold air can enter your home through small openings near pipes and reduce surrounding temperatures. Use caulk or spray foam insulation to seal cracks and holes around windows, doors, and where pipes enter the home. This not only protects your plumbing but also improves overall energy efficiency.During extreme cold spells, especially at night, keep a slow drip from faucets that connect to pipes prone to freezing. This keeps water moving and relieves pressure in the system, reducing the chance of pipe bursts even if water begins to freeze.
