Frozen pipes are one of the most preventable — and most expensive — plumbing emergencies Wheaton homeowners face every winter. When water inside a pipe freezes, it expands and can crack or burst the pipe entirely, leading to flooding, structural damage, and repair bills that can easily reach $5,000 or more.
If you’ve lived in Wheaton for more than one winter, you already know what real cold feels like. We’re talking about January wind chills dropping to -20°F, temperatures that stay below zero for days, and that particular kind of biting cold that seeps through every gap in your 1970s ranch or four gorgeous Victorian two-story on one of those tree-lined streets off downtown. Wheaton’s older housing stock is beautiful, but a lot of those homes have pipes running through uninsulated crawl spaces, exterior walls, and garages that were never built with brutal cold in mind. That’s exactly why frozen pipes are so common here — and why a little prep work in October and November can save you a massive headache in January.
Where Pipes Freeze First
Pipes are most vulnerable in exterior walls, crawl spaces, garages, unfinished basements, under kitchen cabinets on outside walls, and near gaps where cold air enters around utilities. Outdoor hose connections can freeze back into the wall when hoses remain attached. Insulation helps, but stopping drafts and maintaining indoor heat are equally important.
A Practical Cold-Weather Checklist
- Disconnect hoses and close or drain outdoor supply lines where the system allows it.
- Seal obvious air leaks around pipe penetrations without blocking required ventilation.
- Open sink cabinets on exterior walls so warm room air reaches the piping.
- Keep the thermostat at a consistent temperature, including overnight and while traveling.
- Know where the main water shutoff is and confirm it can be operated.
- Have a trusted person check the home during an extended winter absence.
Allowing a small stream of water can help in a short extreme-cold event, but it increases water use and is not a substitute for correcting exposed piping or air leaks. The City of Wheaton specifically notes that running water to prevent freezing can increase utility bills.
If a Faucet Stops Flowing
Assume a frozen pipe and inspect accessible areas for frost, bulging, or leakage. Keep the faucet open and apply gentle heat with warm air or towels. Never use a torch or open flame. If the pipe is inaccessible, visibly damaged, or begins leaking, shut off the main supply and call a licensed plumber. After thawing, inspect the full run because splits may not leak until water pressure returns.
