If you were to measure the total space of the cracks, gaps and holes around the perimeter of an average home, you would find a hole that is roughly three feet square. Imagine how much heat can escape, or moisture can enter, through a space that large. To prevent these problems, inspect the perimeter of your home and apply caulking or weather-stripping wherever necessary. Both caulking and weather stripping can reduce the flow of cold air in, warm air out, and ultimately cut energy costs. How to Caulk: Clean surface by removing dirt, loose paint and old caulk, and thoroughly dry the surface. Determine which caulk to use based on the size of the crack or gap and the surrounding material. Cut the tip off of a tube of caulking at a 45° angle and load it into a caulking gun. The nozzle is tapered, so the amount you cut off determines whether you have a thin, medium or heavy bead of caulk. Cut near the narrow end for a narrow bead or further up for a wider bead. Use a long nail to break the inner seal and to plug the nozzle when finished. Apply caulk by laying a uniform bead of caulk that overlaps both sides, and completely fills, the crack. Remove excess caulking and allow it to dry. Weather-stripping: Apply weather-stripping at joints where two surfaces meet, such as around windows and doors, to provide an airtight seal. There are a few different types of weather stripping and each has its benefits and drawbacks. Once you choose the appropriate weather stripping, follow the instructions for proper application.
- Tape - lasts only one year and should only be used on windows or doors that will not be opened. Tends to dry and loosen within one season
- Felt - lasts one or two years and should be used on the top and/or sides of doors or window frames for sealing gaps of uniformly narrow width
- Foam - This is known as “backer rod” and looks like a foam tube in a roll. It comes in different diameters and lasts one or two years. Use on the bottom of window sashes or around the frames of warped or loose-fitting doors and windows
