It`s still fall temperatures outside, but winter is approaching quickly and now is the time to prepare your home for colder temperatures. One of the simplest things is to fill any cracks around doors and windows with caulking or weather-stripping. It`s best to remove old caulking before applying the new. Foam insulation can also be used to seal gaps around windows. Also check heaters and furnaces to make sure they are in good working condition. Replacing filters will make them run more efficiently. Make sure exterior water taps are shut off and drained to prevent them from freezing. And bring in plants that are susceptible to cold weather.
