An Exhaustive Checklist for Winterizing Your Home

Winterizing your Home:

1. Insulate pipes that run through your attic and other non-heated areas (you’ll want to do this on any outdoor pipes, too).
2. Set up draft guards on any doors that go outside.
3. Seal off your fireplace (unless you plan to use it during the winter).
4. Check for cracks near the indoor frames of windows or doors. If you see them, caulk them just as you would outside.
5. Set up a digital thermostat that automatically reduces the heat when you’re out of the house and warms it back up when you get home.
6. Check your garage and attic for any leaks. Better to find them now before it starts getting icy!
7. Check the temperature on your hot water tank and make sure it’s not exceeding its maximum.
8. Find the direction switch on your ceiling fans and turn them counter-clockwise. This will redirect warm air down instead of moving cold air throughout the room.
9. Check your dryer vent to make sure it’s not clogged up, and if it is, get it professionally cleaned.
10. Replace the filter in your furnace (and check on any other filters around the house).
11. Open the vents for your heating system.
12. Get your heavy blankets and winter sheets out of storage (get help from Dolly if you need some muscle and a truck). Give them a good wash with hot water to clear off any built-up dust or pollen.
13. Change the batteries on your smoke and carbon monoxide detectors.
