Seasonal Checklist for Closing Your Mountain Rental for Winter
Closing a mountain rental for winter is not one job. It is a series of small jobs, done in the right order, before the first hard freeze settles into the valley. A missed pipe, a fridge door left shut, or a plow driver who never got the address can turn a quiet off-season into a spring repair list. Work through the rental room by room, and leave time for a slow final walkthrough.
Mountain properties bring their own variables: freeze-thaw cycles, snow load, long driveways, wildlife, and the chance that no one can reach the house for days after a storm. The checklist below assumes you are closing the rental for the season, not just leaving it between weekend guests. Adjust it for your building, your water system, and your local climate, and write down what you did so next year is easier.
Water First: Drain, Protect, and Shut Down
Water causes more off-season damage than cold air alone. A pipe that splits in a crawlspace can run for weeks before anyone notices. Start at the main shutoff and work outward.
- Shut off the main water valve. Label it clearly and show the location to your caretaker or cleaner. If the valve is stiff, have it serviced before you need it in a hurry. A valve that will not close completely is almost as bad as no valve at all.
- Drain the system. Open the highest and lowest faucets, flush toilets, and drain the water heater according to the manufacturer’s instructions. Turn off power or gas to the heater before draining. If the rental has a well, shut off the pump breaker and drain the pressure tank according to the system’s manual.
- Blow out the lines if you know how. Wrong pressure can damage fixtures. If you are unsure, hire a plumber. This is especially important for lines that run through exterior walls, unheated crawlspaces, or a garage.
- Protect the traps. After draining, pour non-toxic plumbing antifreeze into sink, shower, and tub traps, and into toilet bowls and tanks. Follow local guidance or ask a plumber about your system. Do not use automotive antifreeze.
- Handle exterior water. Disconnect hoses, shut off and drain exterior spigots, and drain irrigation lines. Empty rain barrels and turn them upside down. If you have a sprinkler system, have it blown out by someone who knows the zones and valves.
If you keep the heat on instead of fully winterizing, set a minimum temperature—around 55°F (13°C) is a common target—and open cabinet doors under sinks on exterior walls. That strategy only works if power and fuel are reliable. In a mountain area with long outages, full draining is often safer.
Photograph every valve, breaker, and drain point before you close the house. A labeled photo set in a shared folder is faster than a phone call from a caretaker standing in a cold crawlspace.
Heating, Fuel, and Safety Systems
Decide early whether the rental will be heated or closed dry. A thermostat set low is not a substitute for winterization if the power fails. If you keep heat on, service the furnace or boiler before the season, replace filters, clear vents and intake pipes, and confirm the propane tank or oil supply. Wood stoves need a clean chimney and a secure cap. Gas, oil, and electrical work should go to a licensed professional.
Fuel delivery is part of the closing, not an afterthought. Confirm that the propane or oil company can reach the tank after a snowstorm and that the driveway is plowed wide enough for the truck. Clear snow from exterior vents, and make sure intake and exhaust pipes are not buried by drifts. A high-efficiency furnace can shut down safely—or worse—if a vent is blocked.
Test smoke and carbon monoxide alarms, replace batteries, and leave a fire extinguisher in the kitchen. Do not rely on portable space heaters as freeze protection in an empty building; they are a fire risk. A remote thermostat or temperature alarm can warn you if the heat fails, but only if someone is available to respond. Pair the alarm with a named contact, a spare key, and a plan for who will go to the house if the temperature drops.
Room-by-Room Closing Checklist
Walk the rental with a notepad and work from top to bottom. The goal is to leave nothing that invites mold, mice, or a surprise repair.
Kitchen
- Empty and clean the fridge and freezer. Dry the interior, prop the doors open, and unplug the appliance. Turn off the ice maker and its water supply. A closed fridge in an unheated house can grow mold and hold odors all winter.
- Run the dishwasher empty, clean the filter, and leave the door ajar. Clear the disposal and unplug small appliances.
- Remove open food, pet food, and crumbs. Store sealed goods in lidded bins or take them home. Wipe shelves and drawers, and check behind the stove and under the sink for crumbs or grease.
- Clean the range hood filter and wipe the stove. Leave no grease that can attract pests.
- Take home or lock away small appliances, knives, and anything a winter caretaker does not need. Empty the coffee maker and drain its water reservoir.
Bathrooms
- Drain toilets and add non-toxic antifreeze as above. Remove brushes, soaps, and paper that can hold moisture or feed mice.
- Drain showerheads and hoses. Clean drains and leave the fan vent clear.
- Take home medicines, towels, and bath mats. Check caulk around tubs and sinks; small gaps invite water and cold air.
- Leave cabinet doors open under exterior sinks if the house will be heated at a low temperature. If the house is fully drained, close them after the traps are protected.
Bedrooms and Living Areas
- Wash and store linens in sealed bins. Cover mattresses or stand them on edge if damp air is a concern.
- Unplug electronics, lamps, and chargers. Remove batteries from remotes and small devices. Check that no device is left with a lithium battery that can swell in cold conditions.
- Move furniture a few inches from exterior walls to let air circulate. Close and lock windows; check latches.
- Take home valuables and documents. Leave curtains partly open for light and a lived-in look.
- Roll up rugs or protect them from damp concrete. Vacuum thoroughly, because crumbs and dust are an invitation to mice.
Laundry, Utility, and Entry
- Turn off washer water, disconnect hoses, and drain the pump if the manual shows how. Leave the washer door open. Clean the dryer lint trap and unplug the dryer.
- Clear clutter around the water heater and furnace. Test the sump pump if you have one, and make sure the discharge line slopes away from the foundation.
- Remove boots, mats, pet food, and anything that can freeze or smell. Store snow shovels and ice melt inside a mudroom or locked shed, not where snow burial makes them unreachable.
- Sweep the entry, remove damp mats, and check door sweeps and weatherstripping. Lock spare keys in a secure lockbox or take them home, and tell your caretaker where the key is stored.
Exterior, Roof, and Access
The outside of a mountain rental takes more winter punishment than the inside. Snow load, ice dams, wind, and plow damage are common. Walk the property with the same attention you gave the kitchen.
- Clear gutters and downspouts. Check that downspouts discharge away from the foundation, not into a frozen pile against the wall.
- Inspect the roof from the ground with binoculars. Look for loose shingles, damaged flashing, and gaps around vents. Schedule repairs before the first snow, not after an ice dam forms.
- Trim branches away from the roof and siding. Stack firewood away from the house, not against the wall, and keep it covered.
- Store patio furniture, grills, and garden tools. Shut off propane cylinders at the valve and store them according to local rules, never in a closed basement or crawlspace.
- Mark the driveway, mailbox, propane tank, septic vent, and any buried utilities for the plow driver. Give the driver the exact address, gate code, and a phone number that works in winter.
- Seal obvious gaps around pipes, doors, and foundation vents. Screen vents to keep mice and squirrels out, and remove any food source that would invite wildlife.
- Turn off exterior outlets and cover the air-conditioning condenser if the manufacturer recommends it. Check exterior lighting and replace bulbs so the caretaker can see at night.
Paperwork, People, and Insurance
A winter closing is also a handoff. The house may be empty, but it should not be forgotten. Confirm who is watching it, how often they will visit, and what they are authorized to do.
- Check your insurance policy for vacancy or unoccupancy rules. Some policies require regular inspections or notice when a rental is empty for an extended period.
- Keep liability coverage in place and confirm that the policy covers snow removal, caretakers, and any seasonal workers who visit the property.
- Leave a winter binder with valve locations, breaker labels, appliance manuals, plow contacts, utility account numbers, and the name of the person who can make emergency decisions.
- Forward mail or pause deliveries. A full mailbox is a signal that no one is home.
- Update the rental calendar and guest messaging so no one books the property during the closed period. Set an emergency contact for weather-related questions.
- Schedule at least one midwinter inspection, especially after a heavy snow or a thaw. The visit should include a look for leaks, rodent activity, snow load, and heat failure.
Final Walkthrough and Spring Reopening Notes
Before you lock the door, do one slow final pass. Start at the top of the house and end at the main shutoff. Carry the checklist, a camera, and a note pad.
- Confirm every water source is off or drained. Check under sinks, behind the washing machine, at the water heater, and at exterior spigots. Look for drips and close cabinet doors as appropriate.
- Verify appliance settings. Fridge doors propped open, dishwasher door ajar, washer door open, and small appliances unplugged.
- Check heat and safety systems. Thermostat set as planned, alarms tested, vents clear, and fuel supply confirmed.
- Close and lock all windows and doors. Pull curtains partly closed, but leave enough light for a caretaker to see inside. Set any timers or security lights according to your plan.
- Take out the trash. Empty every bin, including bathrooms and the kitchen. A forgotten bag of garbage can welcome mice and leave a smell that lasts until spring.
- Record the details. Photograph each room, note meter readings, and write down the date, weather, and any repairs to schedule. Send a copy to the owner or property manager.
Finally, leave a short note for your future self. List what needs to be reopened in spring: which breakers to reset, which valves to open, which appliances to plug in, and which inspections to schedule. The best winter closing is the one that makes spring opening boring—no surprises, no water stains, and no repairs that could have been prevented with one more careful walkthrough.
