Closing a lake home for the winter is one of the most important jobs of the year. Miss a step and you could come back in spring to burst pipes, mice or water damage. Use this checklist to close your Michigan lake house or cottage the right way.
Plumbing
- Decide whether the home will stay heated (50–55°F) or be fully closed
- Shut off the main water valve and well pump
- Open faucets and drain all lines from the lowest point
- Drain the water heater and turn it off or to vacation mode
- Disconnect hoses and shut off outdoor hose bibs
- Add RV (non-toxic) antifreeze to sink, tub and floor drain traps and toilets in unheated homes
Yard and Irrigation
- Blow out sprinkler lines and drip zones
- Rake leaves and clean beds. See fall cleanup
- Trim branches away from the roof and power lines
Exterior
- Clean gutters to prevent ice dams
- Store patio furniture, cushions, kayaks and paddleboards
- Clean and cover the grill. Disconnect propane tanks and store them outdoors
- Check the deck for loose boards and railings. See signs of deck rot
- Close crawlspace vents and seal gaps where mice can get in
Inside
- Empty and clean the refrigerator; prop doors open if turned off
- Remove all food that could attract pests
- Unplug electronics and small appliances
- Close blinds and set lights on timers
- Check smoke and CO detectors
Security and Monitoring
- Lock all doors and windows and set the alarm
- Stop mail or forward it
- Install a Wi-Fi thermostat or temperature/water sensor
- Arrange snow removal and a home watch service to check the house regularly
