With colder weather around the corner, one thing you can do to save energy at home is called "draftproofing." Take a lighted incense stick around your home to find hidden drafts. When you hold the stick near walls, attic doors, entry doors, fireplace dampers and windows, see if the smoke goes horizontally. If it does, there's a leak that needs to be sealed. Caulk, foam and weather stripping can help insulate and fix this problem quickly and easily.
