Vermont freezes hard — sometimes by mid-October in the Northeast Kingdom, reliably by Thanksgiving everywhere else. If your seasonal home sits empty through winter, the cost of skipping a step is measured in thousands, not inconvenience.
A burst pipe in an unoccupied home can run for days before anyone notices. Average cleanup cost in Vermont: $8,000 to $15,000. Set your thermostat to 55 degrees minimum. If draining the system, hire a plumber to blow out the lines with compressed air. Disconnect outdoor hoses and shut off exterior faucets from inside. Install Wi-Fi leak and freeze sensors — a $30 sensor is the single best investment in this entire checklist.
Never turn off the heat entirely. Condensation forms inside walls, mold grows, and wood cracks. Set the thermostat to 55 degrees. A smart thermostat lets you monitor remotely. If your home runs on propane or oil, schedule a delivery before closing up. Have the furnace serviced in September or October — technicians are booked solid by November.
Mice can squeeze through a hole the size of a dime. Steel wool and expanding foam around pipe penetrations, foundation cracks, and where utilities enter the house. A chimney cap prevents squirrels, raccoons, and birds from nesting in the flue. Remove all food — not just perishables.
Pour RV antifreeze into every drain trap — sinks, showers, toilets, and the washing machine drain. If your home is on a septic system, note when it was last pumped. Vermont recommends pumping every 3 to 5 years. If you are planning spring renovations that change plumbing, get it inspected before you close up.
Clean the gutters. Inspect the roof from the ground for missing or lifted shingles. Trim branches that overhang the roof. Drain and store garden hoses. If you have a dock, follow your town and ANR requirements for winter storage.
Clean out the refrigerator completely. Unplug it, defrost the freezer, wipe it dry, and prop the door open. Strip the beds and store linens in sealed plastic bins. Close the fireplace damper. Unplug all electronics. Take photos of every room before you leave — invaluable for insurance claims.
Many homeowners insurance policies require that a vacant home be checked periodically — sometimes every 72 hours. If your insurer does not know the home will be unoccupied, a claim could be denied. Call your agent and confirm the vacancy requirements.

Ideally by mid-October. The Northeast Kingdom can see hard freezes in early October.
You can, but it requires a professional air blowout. Most seasonal owners drain exterior lines and keep interior heat on low.
DIY supplies cost under $200. Plumber blowout runs $150 to $300. Full-service winterization is $300 to $600.
55 degrees Fahrenheit. Below 50 and you risk frozen pipes in exterior walls.
