The situation

Illustrative example. Not a real job or customer.

A hypothetical post-war brick rental sits empty for a few weeks between tenants. To save on utilities, the thermostat is set low and the water left on. A strong arctic front brings several nights well below zero. A bathroom supply line in an exterior wall above a crawlspace freezes and splits.

  1. The pipe splits during the cold. When temperatures rise, water starts flowing inside the wall and into the crawlspace below.
  2. With no one in the house, water runs for days. It soaks the bathroom subfloor, the hallway carpet and the drywall in two rooms.
  3. The landlord arrives for a showing and finds water on the floor, a strong musty odor and fogged windows.
  4. The landlord shuts off the main and calls a plumber and the insurer. The insurer asks how long the home had been vacant and what the heat was set to.
  5. A drying contractor treats the water as contaminated because of the time elapsed and contact with the crawlspace soil. Carpet, pad and the lower part of the drywall are removed.
  6. The crawlspace needs cleaning, and visible mold on the framing in one bay leads to containment and a separate remediation scope.
  7. The plumber reroutes the line and insulates the crawlspace section.

Repairs take weeks, and the next tenant's move-in date is pushed back. The claim discussion centers on the vacancy period and heat settings, and the outcome depends on the policy language. The lesson: an empty house needs heat and regular inside checks, especially after cold snaps.

How elapsed time changed the job

If found on the thaw day
Likely a clean-water loss. Carpet and drywall might have been dried in place.
If found a day or two later
More area affected, more materials removed, but likely still manageable.
Found after several days
Water treated as contaminated, porous materials removed, mold remediation needed and a longer timeline.

What could have gone differently

What happened

  • Thermostat set low to save money
  • Water left on with nobody checking
  • No leak or temperature sensors
  • Vacancy terms not reviewed with the insurer

A safer setup

  • Heat kept at a normal level or water shut off and drained
  • Inside checks scheduled, especially after cold snaps
  • Inexpensive sensors sending alerts to a phone
  • Agent consulted before the vacancy began
