Frozen and Burst Pipe Repair in Decatur
A January cold snap in Central Illinois finds every weak spot in a home's plumbing: the kitchen line on an outside wall, the crawlspace under an addition, the hose bib left connected. Here is what to do and how repairs are usually approached.
The short version
No water at one faucet in a hard freeze usually means a frozen pipe. Shut off the water before it thaws if you suspect a split. Repairs fix the split; prevention moves or protects the pipe so it does not happen again.
- Typical asks: no water, burst pipes, frozen hose bibs, crawlspace lines
- Ask about: reroute, insulation, access

How cold it gets
Decatur's average January low is around 17°F, and the record is −25°F, set in February 1905. Arctic outbreaks bring several days below zero in some winters. The Illinois State Climatologist tracks the state's cold records (Illinois State Climatologist), and the National Weather Service Lincoln office issues wind chill and cold warnings (National Weather Service Lincoln, IL).
Where pipes freeze
- Kitchen and bath lines in exterior walls, especially on the north and west sides.
- Crawlspaces under additions, porches and sunrooms.
- Pipes in attached garages.
- Hose bibs left with a hose attached.
- Lines near basement rim joists, where outside air leaks in.
If a pipe freezes
- Find the main shut-off and be ready to close it.
- Open the faucet the line feeds so water can move as it thaws.
- Warm the area gently: a space heater at a safe distance, a hair dryer, warm towels.
- Never use an open flame.
- If you see a split or water spraying, close the main shut-off.
The National Weather Service's cold weather safety pages include advice on protecting pipes (National Weather Service, cold weather safety).
Repairing a burst pipe
A burst usually shows up as a split along the pipe, often a short distance from the frozen spot, where pressure built up. Repair means cutting out the damaged section and replacing it. Access may mean opening drywall or crawling under the house. If a line freezes every winter, the better repair moves it to a warmer spot or adds protection.
Preventing the next freeze
- Insulate pipes in crawlspaces and garages; seal air leaks near pipes.
- Heat cable rated for pipes on lines that cannot be moved.
- Frost-free hose bibs, which shut off inside the warm wall.
- Disconnect hoses before the first hard freeze.
- During cold snaps, open sink cabinet doors on outside walls and let a faucet drip.
- Keep the thermostat steady, even when away.
Water damage
A burst pipe can release a lot of water fast. Shut off the water, turn off electricity to wet areas if it is safe, and photograph the damage. University of Illinois Extension has information on drying out after water damage (University of Illinois Extension).

Frozen & Burst Pipe Repair: what people ask
What should I do if a pipe bursts?
Close the main shut-off valve, then deal with the water and call for repair.
How do I thaw a frozen pipe safely?
Open the faucet and apply gentle heat, such as a hair dryer. Never use an open flame.
Why does the same pipe freeze every winter?
It is in a cold spot, such as an exterior wall or crawlspace. Rerouting or insulation fixes it.
Should I drip faucets in a cold snap?
Letting a faucet on an outside wall drip helps keep water moving and relieves pressure.
What is a frost-free hose bib?
An outdoor faucet whose valve sits inside the warm wall, so the outside part drains.
Does heat cable work?
Pipe-rated heat cable helps protect lines that cannot be moved, when installed per the manufacturer.
