Frozen Pipes in Northern Michigan: How to Prevent Them (And What to Do When It Happens)

If you've lived in Northern Michigan for more than one winter, you already know: the cold here is serious. Temperatures regularly drop well below zero in January and February, and when they do, pipes freeze. It's one of the most common — and most preventable — plumbing emergencies we get called for. And when a frozen pipe turns into a burst pipe, the damage can be catastrophic.

The good news is that most frozen pipe situations are avoidable. A few precautions in the fall can save you from a very bad day in February. And if you do end up with a frozen pipe, knowing what to do — and what not to do — can be the difference between a minor inconvenience and a flooded living room.

Why Pipes Freeze (And Why It's So Dangerous)

Water expands when it freezes — and it expands with enormous force. When water inside a pipe freezes, the pressure it creates has nowhere to go. That pressure either finds a weak point in a fitting, or it simply splits the pipe itself. The pipe doesn't fail while it's frozen, though. It fails when it thaws. That's when the crack opens up and water starts flowing — sometimes in a wall, under a floor, or behind a cabinet, where you may not notice it for hours.

The pipes most vulnerable to freezing are the ones in unheated spaces: crawl spaces, garages, exterior walls, cabins and camps, and any pipe that runs along an outside wall without adequate insulation. In Northern Michigan, where many homes have older construction, basements that aren't fully conditioned, or outbuildings with water running to them, the risk is real.

Prevention: What to Do Before Winter Hits

Most frozen pipe calls are preventable. Here's what to do before temperatures drop hard:

Insulate exposed pipes

Pipe insulation is cheap, easy to install, and effective. Any pipe in a crawl space, garage, or against an exterior wall should be wrapped. Pay special attention to pipes on the north side of the house — those get the coldest air and the least sun.

Disconnect and drain outdoor hoses

A garden hose left connected to a sillcock (outdoor faucet) can trap water in the valve, which freezes and cracks it from the inside even if you have a frost-free sillcock installed. Disconnect hoses before the first hard freeze, every year.

Know where your main shutoff is

If a pipe does burst, you need to be able to kill the water supply fast. Find your main shutoff valve now, make sure it turns freely, and make sure everyone in the house knows where it is. In a burst pipe emergency, every second matters.

Keep heat on in the house — even when you're away

If you're leaving for the holidays or spending a few days at camp, don't turn the heat all the way down. Set it to at least 55°F. The cost of running heat while you're gone is nothing compared to a burst pipe claim. If you're winterizing a cabin or camp for the season, drain the lines properly — don't just turn the heat down and hope for the best.

Open cabinet doors on bitter nights

If you have pipes under kitchen or bathroom sinks on exterior walls, open the cabinet doors on the coldest nights. Letting warm air from the house reach those pipes can make a real difference when it's -10° outside.

What to Do If a Pipe Freezes

You turn on the tap and nothing comes out — or just a trickle. A pipe is probably frozen. Here's what to do:

First, shut off the water to that section of the house— or the main if you can't isolate it. If the pipe is already cracked or split, it will start flowing the moment it thaws. You want to control that.

If you know where the frozen section is, you can try to warm it gently. A hair dryer on low heat, warm (not hot) towels wrapped around the pipe, or a heating pad set to low can help thaw the ice slowly. Start at the faucet end and work toward the frozen section. Never use an open flame, heat gun, or anything above about 120°F — you'll damage the pipe or, worse, start a fire.

If you don't know where the frozen section is, or if it's inside a wall, under a slab, or otherwise inaccessible — call a plumber. Don't start poking through drywall guessing. A plumber can locate the frozen section and thaw it safely without tearing up your home unnecessarily.

Watch carefully when the pipe thaws. Even if the pipe held, check around joints, under sinks, and at any point where the pipe bends. Small cracks can leak slowly and you might not notice for a while.

When to Call a Plumber

Call immediately if:

• You hear water running somewhere inside the wall after a freeze
• You see water staining, bubbling paint, or wet drywall
• The frozen section is in a wall, ceiling, or crawl space
• Multiple fixtures stopped working at the same time
• You can't locate the shutoff valve or it won't turn
• You thawed the pipe and it's still not flowing normally

Even if you think the freeze was minor, it's worth having a plumber check things out. Hairline cracks in copper or PEX can leak slowly for weeks before you notice, and by then you're dealing with mold, rotted subfloor, or damaged insulation on top of the plumbing repair.

A Word About Cabins and Seasonal Properties

Northern Michigan has thousands of camps and cabins that sit empty through the winter. Frozen pipes are one of the most common — and expensive — problems we see when owners open up in the spring. Proper winterization means draining every line, blowing out the system with compressed air, and making sure any water that could sit in a trap or low spot is cleared out. Done right, you can leave a cabin all winter without worry. Done wrong, you'll be writing a big check in May.

If you're not sure your cabin has been winterized correctly — or you've bought a seasonal property and don't know its history — it's worth having a plumber walk through it before winter. An hour of inspection now is a lot cheaper than repairs after a winter of frozen pipes.

Bottom Line

Frozen pipes are one of those problems where a little prevention goes a long way. Insulate, disconnect hoses, keep the heat on, and know where your shutoff is. If something does freeze, act fast — shut off the water, thaw carefully, and don't hesitate to call if you're not sure what you're dealing with.

In Northern Michigan, the cold is part of life. Burst pipes don't have to be.
