An empty property can hide a heating failure or plumbing leak until damage is extensive. Before cold weather, decide whether the building will remain heated or be formally winterized. The correct approach depends on its plumbing layout, appliances, fire-protection systems, lease obligations, insurer requirements, and local codes; involve qualified trades for system changes.
If the property will remain heated
- Set a conservative, manufacturer- and insurer-approved minimum temperature.
- Confirm the heat is operating before vacancy and arrange periodic checks.
- Keep interior doors open where appropriate so warm air can circulate.
- Know who can enter during an outage and who receives alarm notifications.
- Protect exposed plumbing from cold drafts without blocking vents or equipment.
If plumbing will be drained
Use a qualified plumber or property professional familiar with the building. Draining a system incorrectly can damage fixtures, pumps, water heaters, or fire-suppression equipment. Do not shut down a sprinkler system or other life-safety equipment without an approved plan. Record exactly what was isolated, drained, protected, and tagged so the system can be safely returned to service.
Prepare the property and records
Close and secure windows, check exterior doors, remove perishable contents, and make sure a trusted contact has keys and emergency instructions. Photograph meter readings and visible plumbing conditions if useful for your records. Confirm the insurance policy's vacancy requirements and keep inspection dates in a log.
Respond early to warning signs
A sudden drop in indoor temperature, an unusual water-meter change, a leak alarm, or a musty smell warrants prompt attention. If a pipe may be frozen, do not use an open flame to thaw it. Have a qualified professional assess the system and restore service in a controlled way.
