Signs Your Pipes Are Frozen
Michigan winters regularly see temperatures below 20°F, when pipes are at risk. Here's how to tell if your pipes are frozen:
No water from faucet
Turn on faucet and nothing comes out, or just a trickle
Frost on pipes
Visible frost or ice on exposed pipes in basement or crawl space
Strange odors
Sewage smell from drains—frozen blockage trapping odors
Bulging pipes
Pipe looks swollen or has visible cracks—about to burst
Gurgling sounds
Strange sounds when turning on water—partial blockage
Only some faucets affected
If one faucet works but another doesn't, that line is frozen
Warning: If you see bulging or cracks in a frozen pipe, do NOT try to thaw it yourself. Shut off the main water valve immediately and call a plumber. The pipe is about to burst.
How to Thaw Frozen Pipes Safely (DIY)
If the frozen pipe is accessible and not damaged, you can often thaw it yourself. Follow these steps carefully:
Open the faucet
Open both hot and cold handles on the faucet the pipe leads to. This allows water to flow once ice melts and relieves dangerous pressure buildup.
Locate the frozen section
Feel along the pipe for extremely cold spots. Check pipes in exterior walls, near windows, in unheated crawl spaces, and in the basement. Frozen sections often have visible frost.
Apply heat starting at the faucet
Work from the open faucet toward the frozen area. Use a hair dryer, heat lamp, space heater pointed at the pipe, or towels soaked in hot water wrapped around the pipe.
Keep heating until flow returns
Continue applying heat until full water pressure is restored. This can take 30 minutes to 2 hours. Be patient—rushing can damage pipes.
Check for leaks
Once thawed, carefully inspect the entire pipe for cracks, splits, or pinhole leaks. Freezing often causes damage that's only visible once water flows.
NEVER Do These Things
- • Never use a propane torch or open flame — fire hazard and can crack pipes
- • Never pour boiling water on pipes — thermal shock can crack them
- • Never use a kerosene heater indoors — carbon monoxide risk
- • Never ignore a bulging pipe — it's about to burst, call a plumber

What to Do If a Frozen Pipe Bursts
Emergency Steps:
- 1Shut off the main water valve immediately. Usually located near the water meter, where the water line enters your home, or in the basement.
- 2Turn off electricity to affected areas if water is near outlets or the electrical panel.
- 3Call an emergency plumber — don't wait until morning. Water damage gets exponentially worse over time.
- 4Document everything with photos and videos for your insurance claim.
- 5Start removing water with towels, mops, and a wet-vac if you have one. Move valuables to dry areas.
Insurance tip: Most Michigan homeowners policies cover water damage from burst pipes if your home was reasonably heated. Call your insurance company right away to report the incident and get a claim number.

Preventing Frozen Pipes in Michigan
Michigan's harsh winters make frozen pipe prevention essential. Here's how to protect your home:
Insulate exposed pipes
Use foam pipe insulation on pipes in unheated areas like garages, crawl spaces, and attics. Cost: $1-3 per foot.
Seal air leaks
Caulk and weatherstrip around pipes where they enter exterior walls. Cold air infiltration is a major cause of freezing.
Let faucets drip
During extreme cold (below 20°F), let faucets on exterior walls drip. Moving water is harder to freeze.
Open cabinet doors
Keep kitchen and bathroom cabinets open to let warm air reach pipes along exterior walls.
Keep heat at 55°F minimum
Even when away, maintain at least 55°F. Set thermostat the same day and night during cold snaps.
Disconnect outdoor hoses
Before winter, disconnect hoses, drain outdoor faucets, and shut off interior valves to outdoor spigots.
Know your main shutoff
Locate and label your main water valve NOW. In an emergency, seconds matter.
Consider heat tape
For chronically problematic pipes, electric heat tape provides constant warmth. $50-100 DIY install.
Frequently Asked Questions
How do I know if my pipes are frozen?
Signs of frozen pipes include: no water or very low water pressure from faucets, frost visible on exposed pipes, strange smells from drains (trapped sewage), and bulging or cracked pipes. In Michigan winters, pipes in exterior walls, crawl spaces, and unheated areas freeze first.
How much does it cost to fix frozen pipes in Michigan?
Thawing frozen pipes costs $150-$400 in Michigan. If the pipe bursts, repair costs range from $200-$600 for accessible pipes, or $600-$1,500+ for pipes in walls or underground. Emergency/after-hours service adds 50-100% to these costs.
Can I thaw frozen pipes myself?
You can safely thaw accessible frozen pipes using a hair dryer, heat lamp, space heater, or warm towels. Never use open flames, propane torches, or boiling water—these can crack pipes or start fires. If pipes are in walls or you see bulging/cracks, call a plumber immediately.
At what temperature do pipes freeze in Michigan?
Pipes can begin freezing when outdoor temperatures drop below 20°F (-6°C), which is common in Michigan from December through February. Pipes in unheated areas like crawl spaces, attics, and exterior walls freeze fastest. Wind chill makes it worse.
How long does it take for pipes to freeze in Michigan?
In Michigan's extreme cold (below 20°F), unprotected pipes can freeze in as little as 4-6 hours. During polar vortex events with temps below 0°F, pipes can freeze in 2-3 hours. Interior pipes in heated homes rarely freeze unless heat fails.
Should I let my faucets drip to prevent frozen pipes?
Yes, letting faucets drip during extreme cold prevents frozen pipes. The constant water movement makes freezing harder, and the open faucet relieves pressure if freezing occurs—preventing bursts. Focus on faucets along exterior walls.
What do I do if a frozen pipe bursts?
Immediately shut off your main water valve (usually near the water meter or where water enters your home). Then call an emergency plumber. While waiting: turn off electricity to affected areas, remove valuables from water, and document damage with photos for insurance.
Does homeowners insurance cover frozen pipe damage in Michigan?
Most Michigan homeowners insurance covers water damage from burst pipes if you maintained reasonable heat in your home. Coverage typically includes repairs and water damage restoration. However, the pipe repair itself may not be covered. Check your policy and document everything.
