NYC Winter Prep: How to Prevent Frozen Pipe Bursts in Older Buildings

Team NY Water Damage Restoration

When the temperature drops in New York City, the risk to your property rises. In NYC, our unique architecture-from historic Brooklyn brownstones to iconic pre-war Manhattan apartments-presents a major challenge  aging plumbing.

Older buildings are at a high risk for frozen pipes because insulation often settles over time, leaving pipes in exterior walls exposed to the freezing cold. A single burst pipe can cause thousands of dollars in damage in minutes.

How to Prevent Frozen Pipes in NYC

1. Keep the Heat On
Never let your thermostat drop below 55°F, even if you are leaving the city for a few days. For NYC landlords, maintaining heat in basements and utility rooms is the best way to prevent a building-wide disaster.

2. Insulate Exposed Pipes
Use foam sleeves on any pipes located in unheated areas like crawl spaces or near drafty windows. In brownstones, pay close attention to the pipes near the garden-level entrance.

3. Let the Faucet Drip
On sub-zero nights, leave a faucet dripping slightly. This relieves the pressure buildup inside the pipe, which is the actual cause of the “burst” when ice forms.

4. Seal the Drafts
Check for cracks around windows and doors. Even a tiny cold draft hitting a pipe directly can cause it to freeze in hours.

What to Do if a Pipe Bursts

If you discover a burst pipe, you must act fast to save your floors and walls:

  1. Shut off the main water valve immediately.
  2. Call your building Super or a professional restoration team.
  3. Document the damage with high-quality photos for your insurance claim.

For major flooding and structural drying, it is vital to follow the industry standards used by national burst pipe repair experts. By using specialized thermal imaging and high-speed dehumidifiers, you can prevent long-term mold growth in your NYC home.
