Frozen Pipes at 2 AM: How to Thaw Them Safely in a Michigan Cold Snap

You turn on a faucet during a hard Michigan freeze and get nothing but a trickle. That's a frozen pipe — and it needs attention now, because a frozen pipe is often a burst pipe waiting to happen. As the ice expands, it can split the pipe, and the flood usually appears when it thaws and pressure returns. Here's how to handle it safely.

Step 1: Find the frozen section

Open the faucet that isn't working and trace the supply line back toward likely cold spots — exterior walls, crawlspaces, garages, and near hose bibs. A frozen section may show frost on the pipe or feel colder than the rest. Leave the faucet open; running water, even a trickle, helps melt the ice and relieves pressure.

Step 2: Apply gentle, controlled heat

Warm the frozen section using safe, controlled heat: a hair dryer, a space heater kept well away from anything flammable, warm towels, or an electric heating pad wrapped around the pipe. Start near the faucet and work back toward the coldest spot so melting water can escape. Be patient — this can take time.

Step 3: Never use an open flame

This is the one rule that matters most: never use a blowtorch, propane heater, or any open flame to thaw a pipe. It's a leading cause of house fires during cold snaps, and the intense heat can crack the pipe or damage nearby materials. If gentle heat isn't working or you can't reach the frozen section, stop and call a plumber.

Step 4: Watch for a split as it thaws

As the pipe thaws and water starts flowing again, watch closely for leaks. If a split reveals itself, shut off your main water valve immediately and call for emergency burst pipe repair. Catching it at this moment — before the pipe is under full pressure with no one watching — can save you from a flooded home.

When to call a plumber right away

Call for professional help if you can't locate the frozen section, if it's inside a finished wall, if no water returns after reasonable thawing, or if you see any sign of a leak. Our frozen pipe repair and thawing service runs 24/7 through the Michigan winter, and we thaw safely, check for damage, and freeze-proof the vulnerable runs so you're not making this call again. We cover Ypsilanti, Ann Arbor, and the surrounding communities around the clock.

Preventing frozen pipes next time

Once you've dealt with one freeze, prevent the next: insulate exposed pipes with foam sleeves, seal air leaks in crawlspaces and rim joists, keep cabinet doors open so warm air reaches pipes under sinks, disconnect outdoor hoses, and keep your thermostat at a steady temperature — including when you travel. In our coldest stretches, a slow drip from the most vulnerable faucet keeps water moving. Homes with a history of freezing benefit from having a plumber identify and reroute or heat-tape the chronic trouble spots.

Why the same pipe freezes every year

If you're thawing the same line each January, the problem isn't bad luck — it's exposure. Water freezes where a pipe runs through unconditioned space: an uninsulated crawlspace, a garage wall, a rim joist, or a long run to an outdoor spigot. Thawing gets you water back today, but the fix that ends the yearly ritual is addressing the cold: foam insulation, sealing the drafts that pour cold air across the pipe, heat tape on the worst offenders, or rerouting the line to a warmer path. We handle all of that as part of frozen pipe service, and for homes with a chronic trouble spot it usually pays for itself the first winter you don't wake up to a split line.
