Drafty windows can make a room cold and uncomfortable, especially in the winter months. There are many ways to fix drafty windows so that you not only stay warm but also save money on heating costs. Some of the most common ways to fix drafty windows are through insulating supplies and techniques, caulking the window seams properly, and trimming the windows inside and out. Completing these tasks will fix your windows and stop the cool air from seeping into your warm home.
The first step to repair the draft in your windows is to insulate them around the edges. If your windows are trimmed on the inside you will need to remove the trim and caulk. Then purchase small strips of insulation, or you can use a large piece and cut it into small pieces that will fit into the spaces around the window that are lacking insulation. Stuff the insulation into all of the cracks around your windows until you no longer feel air blowing in.
Once you have finished insulating your windows, either replace the trim you removed, or purchase and trim your windows. Window trim is usually made of wood or vinyl, and comes in many different styles and colors. Once you choose what type you want, trim around the windows on the inside and outside of the opening to cover the seams and insulation around the boarder .This will serve as an added barrier against drafts.
The final step is to caulk around the trim. Caulk comes in different colors and varieties. Purchase caulk that is for windows, and make sure to get the color that matches your window trim for a nice finish. Apply the caulk around the edges of the trim for an airtight seal to guarantee your drafty windows are fixed and sealed. A caulk gun or caulk tool can help you complete the task quickly and neatly.
After completing all of these steps you should have an airtight seal on your windows. One way to check is to take a lighter or match, fire it up, and hold it around the window to see if there are any drafts you missed. This should be done at each stage of repair so that you get a proper seal the first time, and you won't have to go back and fix your windows again. If your windows are old and need replacing, this may a short-term fix. Eventually all windows wear down and new ones are necessary. You can use these same techniques when installing replacement windows to get a tight fit and avoid drafts around the windows of your home.
