Be a House Detective

Ever wonder how well your home is sealed against cold and wind? Here's a way to find out with a draft test. Wait for the next windy day. Then hold a lit stick of incense next to windows, doors, electrical boxes, plumbing fixtures and other places where cold air can enter your house. If the smoke moves horizontally, you've found an air leak. You can fix it by caulking, sealing or weatherstripping.
