Every winter in the Chicago suburbs, there are a few nights when the temperature drops well below zero and the wind makes it feel even colder. Those are the nights when pipes freeze. And the calls usually start a day or two later, when temperatures climb and the ice inside a split pipe melts.
Frozen pipes are one of the most common causes of water damage in the area. Here is where they happen, how to prevent them, and what to do if one bursts.
Where Pipes Freeze
Pipes freeze where cold air reaches them and heat doesn’t. In Elmhurst, Burr Ridge, and the surrounding suburbs, the usual trouble spots are:
- Supply lines inside exterior walls, especially on the north and west sides of the house
- Kitchen and bathroom sinks on outside walls, where cabinets block warm air
- Crawlspaces and unheated areas over garages
- Hose bibs that weren’t shut off and drained in the fall
- Pipes near gaps where siding, sill plates, or rim joists let cold air in
- Plumbing in additions or bump-outs with less insulation
Why the Burst Happens After the Freeze
Water expands as it freezes, which builds pressure in the pipe between the ice and a closed faucet. The pipe splits at its weakest point, but ice keeps water from flowing out. When the house warms up or the weather breaks, the ice melts and water pours out of the split at full pressure.
That’s why the damage often shows up at the worst moment, sometimes while you’re at work or away for the weekend.
How to Prevent Frozen Pipes
- Shut off and drain outdoor faucets each fall, and disconnect hoses.
- Open cabinet doors under sinks on exterior walls during cold snaps.
- Let faucets on vulnerable walls drip on the coldest nights.
- Keep the heat at a steady temperature, day and night, including when you travel.
- Seal gaps around rim joists, sill plates, and pipe penetrations.
- Add pipe insulation in crawlspaces and unheated areas.
If a Pipe Bursts
- Shut off the main water valve right away. In most homes, it’s in the basement where the water line enters.
- Turn off power to affected areas if water is near outlets, fixtures, or appliances.
- Open faucets to drain the remaining water from the lines.
- Photograph the damage before cleanup begins.
- Call a plumber for the pipe and a restoration company for the water.
What Restoration Involves
A burst pipe in an exterior wall soaks insulation, drywall, and framing, then runs down into the floor and often into the basement ceiling below. A burst in the ceiling above a garage or in an upstairs bathroom can wet multiple rooms on two floors.
Professional water damage restoration starts with water extraction and a moisture map of every affected space. Wet insulation is removed, drywall is opened where needed, and commercial drying equipment runs until framing and subfloors test dry. Winter air is dry outside but homes are sealed tight, so dehumidifiers are key to getting moisture out.
Once everything is dry, our reconstruction team handles repairs: insulation, drywall, paint, flooring, and trim. We can also help insulate or reroute vulnerable pipes during the rebuild, so the same spot doesn’t freeze again next year.
Insurance and Frozen Pipes
Sudden pipe bursts from freezing are often covered under homeowners policies, but coverage can depend on whether reasonable steps were taken to keep the home heated. If you’ll be away during winter, keep the heat on and have someone check the house, or shut off and drain the water system.
Frequently Asked Questions
What temperature do pipes freeze in Chicago-area homes?
There’s no single number, but risk rises sharply when outdoor temperatures stay below about 20 degrees for several hours, especially with wind. Pipes in exterior walls, crawlspaces, and over garages are the first to freeze.
How do I thaw a frozen pipe safely?
Keep the faucet open and apply gentle heat with a hair dryer, heating pad, or space heater kept a safe distance away. Start near the faucet and work back toward the frozen section. Never use an open flame, and call a plumber if you can’t find or reach the frozen spot.
Should I keep the heat on if I’m traveling in winter?
Yes. Keep the thermostat at a steady temperature, open cabinet doors on exterior walls, and have someone check the house. For longer trips, consider shutting off the main water valve and draining the lines.
Can a frozen pipe burst without me noticing?
Often, yes. The split can stay hidden while the pipe is frozen, then leak heavily once it thaws, sometimes inside a wall. Watch for sudden drops in water pressure, damp spots on walls, or the sound of running water when nothing is on.
