The following is a checklist by Homeadvisor.com to help you as you prepare your home for the winter months.
Be prepared
- Buy a snow shovel now so you’ll have it before winter weather hits.
- Keep extra water and canned food in storage just in case of a heavy snowstorm.
Gutters & downspouts
- Clean gutters and downspouts in mid-fall and double-check them before winter.
- Install leaf guards to keep falling leaves and other debris out of cleared gutters.
Doors & windows
- Examine doors and windows for gaps where warm air can escape.
- Caulk or apply weatherstripping around problem draft areas.
- Install double-paned windows to increase energy efficiency.
Heating system
- Replace the filter in your furnace.
- Give your heating system a test run so you know it will work properly when you need it.
- Hire a heating/cooling expert to check your furnace’s efficiency.
Roofing, chimneys & decks
- Have a contractor look for damaged roof shingles and loose gutters.
- Make sure chimneys and woodstoves are cleaned early in the season.
