December in the Twin Cities always brings the same mix of excitement and concern. The holidays are here, but so is the kind of cold that can turn an excellent plumbing system into an urgent problem overnight. Even a small gap in insulation or a slightly chilly basement can make a water line freeze, crack, or burst once temperatures drop into the deep freeze. Understanding why frozen pipes occur and what you can do to prevent them can save you from a stressful, expensive mid-winter repair.
Why pipes freeze faster in December
As winter settles in, overnight lows fall quickly, and the frost line sinks deeper around your home. When the temperature around a pipe reaches 20°F or below, the water inside begins to freeze and expand. That pressure buildup is often what leads to cracks or full pipe bursts. Homes in older Twin Cities neighborhoods are especially at risk because many basements, crawlspaces, and exterior walls weren’t insulated with modern materials.
Cold spots in the home, like unfinished basements, garages, or under-sink cabinets along outside walls, are usually the first areas where pipes begin to freeze. If you’ve noticed slower water flow during cold weeks, that’s often the first warning sign.
Common places frozen pipes start
Frozen pipes rarely happen right in the middle of a heated room. They usually start in the parts of your home that stay a few degrees colder.
Basement plumbing, exterior wall supply lines, garage pipes, and lines running to outdoor spigots are the most common trouble spots. Even kitchen and bathroom fixtures along outside walls can be vulnerable if the temperature drops quickly and the wall insulation is thin.
If the faucet suddenly only trickles during a cold spell, assume something is freezing behind the scenes. Acting quickly can prevent the pipe from fully bursting.
How to keep your pipes from freezing
A few small habits can make a big difference during a Minnesota December. Keeping cabinet doors open under sinks on exterior walls lets warm air circulate. Allowing faucets to drip slightly during the coldest nights can also reduce pressure buildup inside the line. If certain pipes are consistently cold, adding insulation sleeves is a straightforward solution that helps maintain a more stable temperature.
If you’re unsure where your home might be vulnerable, a quick plumbing maintenance can give you a clearer view of problem areas before they become bigger issues.
What to do if a pipe freezes
If you turn on a faucet and nothing comes out, don’t ignore it. A frozen pipe isn’t just inconvenient; it’s a sign that pressure may be building somewhere along the line. Try gently warming the area with a hair dryer or heat tape if the location is accessible, and never use open flames. If you can’t find the frozen section or if the pipe looks cracked, it’s safest to call a professional.
Frozen pipes can quickly turn into leaks behind walls or under floors, and those hidden issues often cause more damage than the freeze itself. A professional plumbing services team can help diagnose and repair the problem safely before it escalates.
Why preventive care matters in winter
Once a pipe freezes for the first time, it’s more likely to freeze again. Seasonal maintenance checks are one of the easiest ways to avoid repeat issues. A plumber can look for cold spots, aging fixtures, early signs of corrosion, or areas where insulation is lacking. Addressing small issues promptly can help protect your home during the coldest part of winter.
If you’ve already noticed dripping from a fixture or water stains under a sink, it’s a good time to schedule an inspection. The faucets and fixtures service is a helpful place to start if anything looks worn or outdated.
