The best way to close up a lake house for the season is to work through a written checklist covering the water system, appliances, exterior, and security before you leave, and document the condition of the property with photos so you know exactly what you're coming back to in the spring. What you skip on the last day of summer is what greets you on the first day of spring.
The last weekend of lake house season has its own particular feeling.
You're trying to have fun because it's the last one. You're also trying to get everything done before you leave. The kids don't want to help pack up. Someone wants to squeeze in one more boat ride. The cooler still has stuff in it at 4pm when you were planning to leave at 2.
And then you're in the car heading home and you're pretty sure you forgot something but you can't remember what and you're too tired to go back.
Whatever you forgot is going to be waiting for you in March. Hopefully it's just the good flashlight and not the water line you didn't drain.
Here's how to leave with confidence instead of that specific flavor of dread.
Start the day before, not the morning of
The single biggest closeup mistake is treating it like a one-morning job. The day before you leave, start the non-urgent tasks. Run the dishwasher and put everything away. Do a full sweep. Get the laundry done. Check the outdoor furniture situation.
This leaves the morning of for the checklist items that actually require attention and thought, not the kind you do while simultaneously convincing your kids to put their shoes on.
The water system is the most important thing
If temperatures drop below freezing between now and when you come back, the water system is what can turn a seasonal closure into an expensive repair situation.
Turn off the main water supply. Drain the lines. Drain the water heater or set it to vacation mode. Flush the toilets.
If your lake house has a well, know whether it needs to be winterized. If it has dock water lines, those need attention too. If you're not sure what your specific property requires, call someone who does. The cost of a plumber's advice is considerably less than the cost of burst pipes.
The exterior deserves more attention than it usually gets
Bring in or store anything that doesn't need to spend winter outside. Boat cushions, dock accessories, outdoor furniture, life jackets and water toys that can freeze and crack.
Check the dock. Note anything that needs attention before next season. A board that's loose now is worse in April. Take a photo.
Cover the grill. Clear the gutters. Walk the perimeter.
Inside: the things people forget
The ice maker. Turn it off and empty it. The garbage disposal. Run it, clean it. The thermostat. Set to 55F for most northern climates. Unplug anything that doesn't need to be on. The back of the pantry. You will forget something perishable. Do a full sweep.
Document before you walk out
Take photos. The main living areas. The kitchen. The dock. The exterior.
If you share the property with co-owners, these go into the shared notes in your property app with a date. Next spring when someone asks "was that scratch there before?" the answer exists.
It takes five minutes. It has saved countless conversations.
