Pipe Frozen Right Now? Do This First.
- 1. Shut off the main water valve — before the pipe thaws and bursts.
- 2. Open the affected faucet — releases pressure as ice melts.
- 3. Apply gentle heat — hair dryer starting from the faucet end, moving toward the frozen section. Never use a torch.
- 4. If the pipe has burst or you cannot locate the freeze — call a licensed plumber immediately.

Prevention — Before the Next Polar Vortex
Do Before Winter
- • Wrap exposed pipes in exterior walls with foam insulation
- • Install self-regulating heat tape on crawl space and garage pipes
- • Disconnect and drain outdoor hose bibs
- • Locate and label your main shut-off valve
- • Seal air gaps at rim joists with spray foam
During a Polar Vortex Event
- • Let faucets on exterior walls drip slowly (cold + hot)
- • Open cabinet doors under sinks on exterior walls
- • Keep garage doors closed — especially if supply lines run through
- • Keep home heat at 65°F+ even when away
- • Check crawl space access is sealed from cold air infiltration
Never: Use an open flame torch or propane heater to thaw pipes. This causes fires and has killed Metro Detroit homeowners. A hair dryer or heat gun on a low setting is the maximum heat to apply directly to a pipe.
Frequently Asked Questions
What should I do if my pipes freeze in Metro Detroit?
If pipes are frozen in your Metro Detroit home: (1) Shut off the main water valve immediately — pipes freeze then thaw and burst, and you need the water off before that happens. (2) Open affected faucets to relieve pressure. (3) Apply gentle heat — hair dryer, heat lamp, or electric heating cable — starting from the faucet end toward the frozen section. (4) Never use an open flame torch. (5) Call a licensed plumber if you cannot locate the freeze point or if pipes have already burst.
Which pipes freeze first in Metro Detroit homes?
In Metro Detroit homes, pipes freeze first in: (1) exterior wall cavities — supply lines running through uninsulated or poorly insulated exterior walls, especially north-facing. (2) Crawl space pipes — homes with unheated crawl spaces lose pipe temperature quickly. (3) Garage walls — especially in attached garages with water supply lines to a laundry or utility sink. (4) Basement rim joist area — where the floor joist meets the foundation wall, often drafty. (5) Attic pipes — rare but severe when present.
How much does frozen pipe repair cost in Metro Detroit?
Frozen pipe thawing in Metro Detroit costs $200–$400 for a standard emergency service call. If the pipe has burst, repair costs $300–$800 for a typical section replacement, not including drywall repair. Emergency after-hours service during polar vortex events adds 50–75% to standard rates. Call during business hours when possible to avoid the emergency premium.
At what temperature do pipes freeze in Metro Detroit?
Pipes in unheated spaces typically freeze at sustained outdoor temperatures below 20°F (-7°C). Metro Detroit regularly hits single digits and negative temperatures during polar vortex events — sometimes -20°F (-29°C) or lower. At these temperatures, poorly insulated pipes in exterior walls and crawl spaces can freeze within 6–12 hours. Pipes with running water freeze more slowly than stagnant pipes.
How do I prevent pipes from freezing in my Metro Detroit home?
Prevention for Metro Detroit's polar vortex winters: (1) Insulate pipes in exterior walls, crawl spaces, and garage with foam pipe insulation ($0.50–$2/ft). (2) Install heat tape (electric heating cable) on vulnerable pipes — automatic models that activate below 40°F are best. (3) Keep garage doors closed when temperatures drop below 20°F. (4) Let faucets drip on exterior wall lines during extreme cold events. (5) Keep cabinet doors under sinks on exterior walls open to let warm air circulate. (6) Know where your main shut-off valve is before a freeze hits.
Should I call a plumber or do it myself for frozen pipes?
Call a plumber if: you cannot locate where the pipe is frozen, the frozen section is inside a wall or floor, you hear cracking or see bulging (imminent burst), the pipe has already burst, or the freeze is in a supply line you cannot safely access. DIY thawing is appropriate for accessible pipes — under sinks, in basements — using a hair dryer or heat lamp with the water shut off first. Never use an open flame.
Does homeowners insurance cover frozen pipe damage in Michigan?
Most Michigan homeowners insurance policies cover sudden and accidental water damage from burst frozen pipes — but coverage depends on your specific policy and whether the home was properly maintained and heated. Coverage is typically denied if the home was unheated or if pipes were not adequately protected. Document all damage immediately with photos and video before any cleanup. Call your insurance company before starting repairs.
