Here are some tips for winterizing your home.   

1. Inspect your furnace and heating system. Have a professional ensure that your heating system is running efficiently and safely. Systems based on gas and oil could potentially release dangerous levels of carbon monoxide that can result in death.
2. Find and fix air leaks. Worn or damaged weather-stripping can cause heat to escape. Locate sources of air leaks around doors and windows, install new weather-stripping, caulk around windows and where plumbing/ducting creates a path to the outside. Don't forget to caulk around the exterior electrical outlets as well.
3. Inspect your windows. Windows let light in but also provide a path for the greatest loss of heat from your home. If your windows are older you can install storm windows over single-pane glass or heavy plastic on the inside. This will prevent heat from escaping. You may also want to invest in a set of insulated drapes.
4. Clean the eaves trough and gutters. Leaves and dirt may have collected through the autumn months. This can cause water to build up which can form ice dams in winter. This can result in serious water damage to your roof and shingles if left unattended before the freezing temperatures arrive.
5. Close the fireplace flue. If you have a fireplace keep in mind the chimneys are designed to suck air upwards. This can carry large amounts of heat out of your house quickly. Ensure the flue is closed when the fireplace is not in use and seal those that will not be used in the winter months.
6. Wrap your pipes near exterior walls. Pipes near exterior walls or those in crawl spaces have the highest risk of freezing during those cold winter months. Wrapping those pipes with insulation provides added protection and can prevent major damage should the pipes freeze and burst throughout the winter months.
