Winterize Your Home: Inside and Out — 2026 Complete Guide
Part 20 of 22 in Winterize Your Home: Inside and Out. By Damon Fowler, Trends Kitchen & Bathroom Specialists.
Leaving for a long weekend and closing an unoccupied property for months are different tasks. The preparation depends on the building, its systems, how long you will be away, and who can respond. A thermostat setting and a locked door are not a complete vacancy plan.
Identify what still needs water and power
Fire sprinklers, hydronic heating, humidifiers, well systems, sump equipment, and other installations can complicate a blanket instruction to shut off utilities. Ask the relevant service professional before changing supply arrangements. A main water shutoff does not empty all plumbing or protect every appliance.
For an extended unheated vacancy, obtain a professional winterization plan. Draining domestic plumbing and treating appropriate fixtures requires a system-specific procedure. Do not pour automotive antifreeze into household plumbing or assume a partially drained system is safe.
Situation: the thermostat alert works, but nobody can get inside
A temperature monitor sends a warning while the homeowner is away. The designated neighbor has no key, does not know the alarm code, and cannot locate the main water valve. The warning is useful only if someone can act on it.
Choose a responsible local contact, confirm access, and provide a short instruction sheet. Include your service contacts, shutoff locations, equipment information, and what circumstances require an immediate emergency call rather than an attempted repair.
Arrange inspections with a purpose
Ask the person checking the home to verify heat, inspect known vulnerable plumbing, look at the basement, and report visible leaks or unusual conditions. A glance through the front window does not establish that the mechanical room is functioning.
Review your insurance policy’s vacancy, inspection, and freeze-protection conditions. They may affect how often checks are required and what records you should keep. Get clarification from the insurer rather than relying on a generic online travel checklist.
Use sensors to support the plan
Leak and temperature sensors can add useful warning at selected locations. Consider under-sink areas, a mechanical room, a basement, or a historically cold addition. Confirm power, battery life, connectivity, alert recipients, and behavior when internet service fails.
An automatic water-shutoff system also needs to suit the building’s water-dependent equipment. Have it specified and installed appropriately. Technology reduces some risks but does not eliminate the need for maintenance and response.
Complete the departure walkthrough
Confirm that hoses are disconnected, heat operates, vulnerable areas are accessible, and the sump discharge is clear. Set controls deliberately rather than leaving temporary holds or old schedules in place. Inspect appliance connections and close windows fully.
Leave contact instructions where the authorized person can find them, and check the forecast before departure. On return, inspect for signs of leakage and confirm normal operation before assuming an uneventful trip means the house had no trouble. Travel preparation is strongest when observation, equipment, and a human response work together.
