How to Prevent Frozen Pipes in a Hard Freeze (Homeowner Guide)

Michigan winters are no joke. When temperatures dip into the teens – or even below zero – homeowners across the state start worrying about the same thing: frozen pipes. It’s a problem that can strike even well-prepared households, especially during sudden cold snaps or prolonged hard freezes. And while frozen pipes are stressful enough on their own, the real trouble often comes later, when ice thaws and water gushes into places it should never be.

The good news? A little bit of preparation goes a long way. Whether you’re a first-time homeowner or a long-time Michigander, this guide will walk you through a series of simple steps to keep your pipes flowing and your home dry – no plumbing degree required.

In our state, temperatures can swing dramatically within 24 hours. A mild day can quickly be followed by a deep freeze, surprising unprotected plumbing in older and newer homes alike. Pipes that run through unheated areas – like crawl spaces, attics, garages, basements, and exterior walls – are especially vulnerable.

When water inside the pipes freezes, it expands. That pressure is what can cause a pipe to burst. And once the ice melts? You’re suddenly dealing with an unexpected indoor waterfall and the need for water damage restoration.

Michigan’s mix of older housing stock, lake-effect weather, and unpredictable cold snaps means residents must be especially proactive.

1. Keep the Heat Consistent

You don’t need to crank the thermostat high, but you do want to keep your home at a steady temperature. During an extreme cold spell, avoid lowering the heat at night. A consistent indoor temperature helps protect pipes hidden behind walls and in less-insulated spaces.

2. Let Faucets Drip

Letting a slow trickle of water run from your faucets during a severe freeze helps keep water moving – making it less likely to freeze. This is especially useful for faucets on exterior walls or in colder parts of the home.

You don’t need a steady stream – just a drip is enough to relieve pressure if ice starts forming.

3. Open Cabinet Doors

Under-sink cabinets, especially in kitchens and bathrooms, often block heat from reaching pipes. Opening the doors allows warmer air to circulate and can make a big difference during a hard freeze.

This small step is particularly helpful for homes with pipes in exterior walls.

4. Seal Drafts and Cold Entry Points

Cold air sneaking in through cracks or gaps can drop the temperature around pipes quickly. Check for drafts near windows, foundation openings, sill plates, and around hose bibs.

Weather stripping, caulk, or a bit of insulation foam is usually enough to handle small gaps. You don’t need to be an expert to make your home less drafty.

5. Disconnect and Drain Outdoor Hoses

Before winter hits, always disconnect hoses and shut off outdoor spigots if your home has an interior shutoff valve. Water trapped in a hose or exterior line is one of the most common causes of frozen pipes.

If you didn’t disconnect the hose before the freeze, do it as soon as temperatures rise above freezing – it still helps.

6. Keep Interior Doors Open

Interior doors help spread warm air throughout the house. Keeping them open allows your heating system to work more evenly, reducing cold spots where pipes might freeze.

7. Add Pipe Insulation in Vulnerable Areas

Pipe insulation is an inexpensive, simple, homeowner-friendly upgrade that can help with pipes near exterior walls or in unheated areas. Foam sleeves or insulated tape are easy to apply and available at any hardware store.

You don’t need to insulate every pipe in the house, but focusing on the coldest zones pays off quickly.

8. Protect the Garage

If your garage contains water lines – or even if it’s attached to your house – keep the door closed as much as possible during a freeze. Cold air pouring in lowers the temperature in surrounding rooms and walls.

Even with preparation, pipes sometimes start freezing before you realize there’s a problem. Watch for:

• Very slow water flow.
• No water flow from a faucet that was working earlier.
• Frost on exposed pipes.
• Unusual noises in the plumbing (whistling, banging, or clanking).

If you suspect a pipe is freezing, act quickly. Turn on the faucet to relieve pressure and try gently warming the pipe area with a hair dryer or by opening nearby cabinets. Avoid open flames or high-heat devices – they’re dangerous and unnecessary.

If you discover a burst pipe, shut off the home’s main water supply immediately. Then, turn on faucets to let remaining water drain out. The faster you act, the better chance you have of minimizing damage.

Once the immediate situation is under control, you may need water damage restoration to dry out your home, prevent mold growth, and repair damaged materials. Prompt action is always best after water intrusion, especially in cold weather when moisture lingers.

Protecting your home from frozen pipes is mostly about preparation and awareness. Still, accidents happen – even to homeowners who do everything right.
