How to Prevent Frozen Pipes Before Minnesota Winter Arrives
Minnesota winters are known for freezing temperatures, heavy snowfall, and long stretches of subzero weather. While many homeowners prepare by servicing their furnace or stocking up on snow melt, one of the most expensive winter hazards is often hidden behind walls and beneath floors: frozen pipes.
When water freezes inside a pipe, it expands. That expansion creates pressure that can eventually cause the pipe to crack or burst. Once temperatures rise or the pipe begins to thaw, water can escape rapidly, causing significant damage to drywall, flooring, insulation, cabinets, furniture, and personal belongings.
At Anytime Restoration, we’ve helped Twin Cities homeowners recover from countless burst pipe emergencies. Fortunately, many of these losses can be prevented with a little preparation before winter arrives.
Why Do Pipes Freeze?
Many people assume pipes only freeze when temperatures fall below zero, but freezing can begin whenever temperatures drop below 32 degrees, especially if pipes are exposed to cold air.
Pipes are most vulnerable when they are located in:
- Exterior walls
- Unheated basements
- Crawl spaces
- Garages
- Attics
- Utility rooms
- Cabinets along exterior walls
Poor insulation, air leaks, and inadequate heating all increase the likelihood of frozen plumbing.
Pipes Most Likely to Freeze
While any water line can freeze under the right conditions, some areas deserve extra attention before winter.
Common trouble spots include:
- Kitchen sink plumbing on exterior walls
- Bathroom plumbing near outside walls
- Laundry rooms
- Garage water lines
- Outdoor hose bibs
- Basement rim joists
- Crawl space plumbing
Inspecting these areas each fall can help identify problems before cold weather sets in.
Insulate Exposed Pipes
One of the easiest and most affordable ways to reduce the risk of frozen pipes is to add insulation.
Foam pipe insulation is available at most home improvement stores and installs quickly on exposed plumbing.
Pay particular attention to pipes located in:
- Basements
- Crawl spaces
- Utility rooms
- Garages
Even a small amount of insulation can provide additional protection during extreme cold.
Disconnect Garden Hoses
Leaving a garden hose attached to an outdoor faucet may trap water inside the pipe.
As temperatures drop, that water can freeze and expand into the home’s plumbing system.
Before the first freeze:
- Disconnect all hoses.
- Drain exterior faucets.
- Shut off exterior water supplies if your home has interior shutoff valves.
- Install insulated faucet covers if desired.
These simple steps take only a few minutes but can prevent significant damage.
Seal Air Leaks
Cold air entering your home through small openings can expose nearby plumbing to freezing temperatures.
Inspect areas around:
- Windows
- Doors
- Utility penetrations
- Foundation openings
- Basement windows
Adding weatherstripping or caulk can improve both energy efficiency and pipe protection.
Keep Your Home Warm
Even if you’re away for the weekend, avoid setting your thermostat too low.
Most professionals recommend maintaining indoor temperatures of at least 55 degrees during winter.
Consistent indoor heat helps keep plumbing inside walls above freezing.
Open Cabinet Doors During Extreme Cold
Pipes located beneath kitchen and bathroom sinks often receive less warm air than the rest of the home.
During especially cold weather, open cabinet doors to allow heated air to circulate around the plumbing.
This simple step can help reduce the chance of freezing.
Let Faucets Drip During Severe Cold
If temperatures are expected to remain extremely cold for an extended period, letting a faucet drip slowly can help relieve pressure in the plumbing system.
Moving water is less likely to freeze than standing water.
While this should not replace proper insulation or heating, it can provide additional protection during dangerous cold snaps.
Know Where Your Main Water Shutoff Is
If a pipe bursts, every minute counts.
Every homeowner should know:
- Where is the main water shutoff valve located
- How to turn it off
- How to access it quickly
Stopping the water supply immediately can significantly reduce the amount of damage inside your home.
What If a Pipe Freezes?
If you suspect a pipe has frozen but has not burst:
- Leave the faucet connected to that pipe open.
- Warm the area gradually using your home’s heating system or warm air.
- Never use an open flame or propane torch.
- Continue monitoring the pipe as it thaws.
If you’re unable to safely thaw the pipe, contact a licensed plumber.
What If a Pipe Bursts?
Burst pipes can release hundreds of gallons of water in a short amount of time.
If this happens:
- Shut off the main water supply immediately.
- Turn off the electricity if water is near electrical components and it is safe to do so.
- Remove valuable belongings from affected areas.
- Contact your insurance company.
- Call a professional water damage restoration company as soon as possible.
Quick action can dramatically reduce secondary damage.
Why Fast Water Damage Restoration Matters
Water damage doesn’t stop when the leak stops.
Within hours:
- Drywall begins absorbing water.
- Flooring may swell or warp.
- Insulation becomes saturated.
- Cabinets can begin deteriorating.
- Moisture spreads into hidden spaces.
Within 24 to 48 hours, mold growth may begin if materials are not properly dried.
Professional restoration equipment, including commercial air movers, dehumidifiers, moisture meters, and thermal imaging cameras, helps ensure that moisture is completely removed.
Preventing Frozen Pipes Is Easier Than Repairing the Damage
A few hours of preparation each fall can help protect your home from one of Minnesota’s most common winter emergencies.
Simple maintenance such as insulating exposed pipes, sealing air leaks, disconnecting hoses, and maintaining indoor temperatures can greatly reduce the risk of frozen plumbing.
While no prevention plan can eliminate every possibility, being proactive can save thousands of dollars in repairs and help you avoid the stress of an unexpected water loss.

Frequently Asked Questions
At what temperature do pipes usually freeze?
Pipes can begin freezing when temperatures fall below 32 degrees, especially if they are exposed to cold air or located in unheated areas.
Should I let my faucets drip during cold weather?
Allowing faucets to drip slowly during extreme cold can help reduce pressure inside the plumbing system and lower the risk of frozen pipes.
Can frozen pipes thaw on their own?
Yes, but thawing pipes can still burst if pressure builds up in the plumbing. It’s important to monitor the situation carefully and shut off the water if a leak develops.
Does homeowners’ insurance cover burst pipes?
Many homeowners’ insurance policies cover sudden and accidental water damage from burst pipes, although coverage varies by policy. Contact your insurance provider to understand your specific coverage.
