How to Prepare Your Commercial Property for Cold Weather (and Protect Your Investment)

Imagine: you’re about to close on selling a large commercial building. Everything has gone smoothly up to this point, and today is your final walkthrough. You step up to the entrance, turn the key, and open the door…only to find water pooled at your feet.

This is not a thought experiment but a true story. One of our clients was on a final walkthrough to purchase a vacant property when they discovered a pipe had burst. The seller had to pay the buyer a substantial amount to repair the plumbing, which could have been avoided with proper maintenance.

Cold weather can pose significant risks to commercial buildings, especially vacant ones. To prevent this from happening to your property, there are several steps you can take to prepare for the cold months ahead.

How to Prevent Frozen Pipes in Vacant Properties

As our client experienced, vacant buildings are at a higher risk of frozen pipes bursting. When temperatures are lower and water is not in daily use, pipes are much more likely to freeze over. And when vacant properties are not regularly inspected, undetected leaks can exacerbate the problem. Here are some actionable steps you can take to help prevent frozen pipes:

• Leave cabinet doors open under sinks.
• Seal drafts around windows and doors.
• Use heating tape on vulnerable pipes.

If the building will remain vacant for an extended period, consider shutting off the water supply and draining the pipes to prevent potential damage. You can also use a non-toxic antifreeze specifically designed for use in plumbing systems.

How to Winterize and Maintain a Vacant Property

Beyond frozen pipes, neglecting a vacant commercial property poses numerous risks, including structural damage, mold, and vandalism. A well-maintained vacant building helps retain value and marketability for future tenants or buyers. Here are a few proactive steps you can take as a commercial property owner this winter:

Heating

• Maintain consistent heat: Keep the thermostat set to at least 55°F (13°C) to prevent frozen pipes.
• Service the HVAC system: Have a professional tune up the heating, ventilation, and air conditioning system to ensure it’s working correctly.
• Install temperature monitors or alarms that can alert you or your property manager to drops in temperature.

Security

• Lighting: Keep exterior lights on timers or motion sensors to deter trespassers.
• Alarm systems and cameras: Invest in smart security systems for remote monitoring.
• Check mail regularly: Monitor the mailbox to ensure your property doesn’t look unoccupied due to a buildup of mail.

Upkeep and Maintenance

• Snow and ice removal: Clear entrances, roofs, and walkways to prevent slips and water damage.
• Roof and gutter care: Inspect for ice dams and ensure drainage is clear.
• Interior checks: Schedule regular property visits to watch for condensation, leaks, or pest activity.

What Temperature Should You Leave an Unoccupied Property?

Generally, the heat should be kept no lower than 55°F (13°C), but adjust according to your region and building design. For properties with sprinkler systems or fire suppression, follow local code requirements for minimum heating. Note that maintaining a minimum temperature is often required by insurance policies to keep the policy valid.

The Takeaway

Preventive maintenance for cold weather protects your property value—and your time. To protect your vacant commercial building from the effects of winter weather, ensure you’re following proper heating and plumbing measures and regularly checking the building = for security and maintenance. Schedule a winter inspection with your maintenance team this fall to ensure your property is protected.
