How to Prevent Pipes from Freezing in My Boston Home

Every winter, freezing temperatures put Boston homes at risk for frozen pipes. When water inside your plumbing freezes, it expands, leading to cracks, burst pipes, flooding and costly repairs. 

Preventing frozen pipes is essential for protecting your property and avoiding emergencies during the coldest months.

Steps to Prevent Pipes from Freezing

Boston’s harsh winters demand proactive pipe protection. Here’s how you can safeguard your home’s plumbing:

• Insulate exposed pipes in unheated areas (basements, attics, garages, crawl spaces) with foam pipe insulation or heat tape.
• Seal gaps and cracks in exterior walls and foundations to block cold air from reaching pipes.
• Keep garage doors closed, especially if water supply lines run through the garage.
• Open cabinet doors under sinks to allow warm air to circulate around pipes  — especially those on exterior walls.
• Let cold water drip from faucets served by exposed pipes during extreme cold. Even a small trickle can prevent freezing.
• Maintain consistent heat throughout your home, even when you’re away. Never set your thermostat below 55°F in winter.

How to Tell If Your Pipes Are Frozen

Recognizing the signs of frozen pipes early can help you act fast:

• Little or no water flow from faucets during very cold weather
• Frost visible on pipes
• Unusual clanking or banging noises when using plumbing fixtures
• Damp drywall or water stains indicate a possible burst

What to Do If Your Pipes Freeze

If you suspect a pipe has frozen, act quickly to minimize damage:

• Shut off the main water supply to prevent flooding.
• Open affected faucets to relieve pressure and allow thawed water to escape.
• Apply gentle heat to the frozen section using a hair dryer, heating pad or warm towels. Never use open flames or torches.
• Start thawing near the faucet and work toward the coldest section.
• If you can’t locate the frozen area, can’t access it or can’t thaw the pipe, call a licensed plumber right away.
