You might not consider that a great way to winterize your home is to inspect the exterior of your house for cracks. A crack along the outside of your home lets heat out, making it more difficult to keep your house warm, and increasing your monthly energy use and costs. Even houses with siding around the outside could have cracks along the fireplace, or even under the eaves. Windows and doors are the most popular areas for cracks.
When you’ve found the problem areas, you can easily fill the cracks with a caulking compound. Apply a generous amount of caulking directly into the cracks and smooth the caulking out with your finger or a tool. Be sure to seal the crack completely as you smooth out the caulking.
Simple steps like this will help you prepare for the cold months, and in the long run will cut down on costs.
