Cold Weather Alert: How to Protect Your Home From Frozen Pipes in Massachusetts

Forecasters are predicting a significant cold blast this coming weekend, with sustained below-freezing temperatures expected from Friday through Monday across Massachusetts.

When temperatures drop this low for extended periods, the risk of frozen — and burst — pipes increases significantly, especially in unoccupied homes, condos, and properties with exposed plumbing.

A little preparation now can help prevent costly water damage, emergency repairs, and unnecessary stress. Here are several simple but important steps homeowners can take to protect their property during extreme cold.

Why Frozen Pipes Are a Serious Risk During Extreme Cold

Frozen pipes occur when water inside plumbing freezes and expands, putting pressure on the pipe walls. When the ice thaws, pipes can crack or burst, releasing water quickly and causing major interior damage.

Homes most at risk include:

• Unoccupied properties

• Condos with exterior-facing plumbing

• Homes with garages beneath living space

• Older properties with limited insulation

In Massachusetts winters, frozen pipes are one of the most common — and expensive — cold weather issues homeowners face.

Keep the Heat On — Even If Your Home Is Empty

Even if your home or condo will be unoccupied, it’s critical to keep the heat running consistently.

Best practices include:

• Set your thermostat to a steady temperature day and night

• Avoid lowering the heat overnight

• If using a smart thermostat, temporarily disable aggressive energy-saving schedules

Maintaining consistent heat allows warm air to circulate through walls, ceilings, and floors — helping protect pipes hidden behind drywall.

Shut Off and Drain Water Lines Where Possible

Taking a few minutes to shut off and drain water lines can greatly reduce the risk of frozen or burst pipes.

Recommended steps:

• Drain and shut off all exterior spigots

• Identify and clearly label your main water shut-off valve

• Shut off the water supply to washing machines if traveling

Knowing where your shut-off valve is before an emergency occurs can save valuable time and limit damage if a pipe freezes or bursts.

Let Warm Air Circulate Around Plumbing

Warm air movement is one of the most effective defenses against frozen pipes.

Helpful tips:

• Open kitchen and bathroom cabinet doors to allow heat to reach pipes under sinks

• Keep doors closed between living space and attached garages

• Seal drafts near plumbing where possible

Even small changes in airflow can make a meaningful difference during extreme cold snaps.

Cold Weather Preparation Can Prevent Costly Damage

Cold snaps like this don’t happen often — but when they do, the damage can be significant if homes aren’t prepared.

By taking these simple precautions now, homeowners can avoid emergency repairs, water damage, insurance claims, and long-term disruption.

Stay warm, stay safe, and protect your home this weekend.

FAQ

How cold does it need to be for pipes to freeze?
Pipes can begin freezing when temperatures fall below 32°F, especially if exposed to exterior walls or unheated spaces.

Should I leave water dripping during extreme cold?
In some cases, a slow drip can help prevent freezing by keeping water moving, but it should be combined with proper heating and insulation.

Are vacant homes at higher risk for frozen pipes?
Yes. Unoccupied homes are especially vulnerable if heat is turned down too low or airflow around plumbing is limited.

What should I do if I think a pipe has frozen?
Shut off the main water supply immediately and contact a licensed plumber. Early action can prevent serious damage.
