Cabin and lake house closing checklist for the end of the season

Updated October 23, 2026

Frozen pipes, mice in the pantry and a dock damaged by ice are some of the most expensive surprises a cabin can hand you in spring. A proper closing routine prevents most of them – and when several families share the place, a shared checklist makes sure nobody assumes "someone else" drained the water.

Important: every property is different. Follow the instructions for your water system, water heater and septic, and ask a plumber or your insurer if you're unsure.

Water

  • Shut off the main water supply.
  • Drain the lines: open every faucet, the shower and outdoor spigots until they stop running.
  • Drain or winterize the water heater according to the manufacturer's instructions.
  • Flush the toilets and empty the tanks.
  • Traps and drains can freeze. Many owners add RV/plumbing antifreeze to drains, sinks and toilets – check what's safe for your septic system.
  • If you have a well pump or water softener, follow its winter procedure.

Heat and power

  • Decide whether the cabin stays heated. If it does, set a low, safe temperature and make sure pipes in cold spots are insulated.
  • Unplug appliances and electronics.
  • Have the chimney and wood stove checked before next season; test smoke and CO detectors.

Food, pests and moisture

  • Remove all food mice can get to; keep dry goods in sealed containers.
  • Empty, clean and unplug the fridge, and prop the door open.
  • Take home bottles and cans that could freeze and burst.
  • Make sure vents are open so moisture doesn't build up.

Outside

  • Bring in outdoor furniture, cushions, hoses and anything wind can carry off.
  • Take out the boat, dock sections or lifts as your lake requires.
  • Clean the gutters and check the roof before snow arrives.
  • Arrange snow plowing if anyone will visit in winter.

Lock up

  • Lock every door and window, including sheds and the boathouse.
  • Put the key back in the lockbox and scramble the code.
  • Note anything broken or needing repair before next season.

Share the job – and the checklist

FamilyHut gives your cabin its own winter closing checklist, with the items above as suggestions you can adjust. Everyone in the family ticks items off on their own phone and sees who did what – so nobody has to wonder whether the water really was drained. In spring there is a matching opening checklist.

Add the closing as a to-do with one person responsible and a due date, and log the electricity and water meters before you leave. Recurring jobs, like sweeping the chimney or changing smoke detector batteries, can be set up once and come back every year.
