Weather stripping the doors and windows in your home is important for a number of reasons. For one, weather stripping will prevent moisture leaks and problems with condensation – moisture problems that can also present the risk for mold, mildew and cracking paint. Also, weatherstripping is important for the sake of maintaining the temperature of your home. In the wintertime, you want to make sure that your windows and door frames are properly sealed for the sake of keeping the warm air in and the cold air out. The same goes for the summertime – except you want to keep the cold air in and hot air outside. Here is how to replace old weatherstripping on doors and windows in your home.
First, you want to know whether or not your windows and doors need new weatherstripping. One of the best ways to know if you need to reseal is if you notice visible cracking and crumbling of the old stripping. Another way to know if you need to place new stripping on your doors and windows is if your utility bills are getting higher. Having properly sealed windows and doors is one of the best ways to maximize furnace efficiency, but if there isn’t enough sealant, you could be dealing with more expensive energy bills and a larger carbon footprint.
Once you identify the areas of your window and door frames that need new sealant, you want to be able to properly remove the old stripping. You can usually do this by literally stripping the old sealant off. If the old sealant is particularly flakey, you may want to use a thin painter’s knife to remove the stripping. It should all come off very easily, especially if it has been caked in the sun or if you have an older home with older doors and windows. After you remove the old sealant, you can clean the area and prep it for new weatherstripping.
Next, you want to apply the new weatherstripping. There are many ways to do this, but the easiest way is to simply apply it directly to your window casing. Depending on the materials you use, you usually don’t need any extra tools. However, if you are using adhesive stripping, you may need to have a separate applicator to apply the glue. On door frames, you may also want to include a metal weatherstrip, which is installed at the foot of the door. After you apply the stripping, you can simply let it dry.
Lastly, you may have to do some post-stripping work after you apply the new sealant, but not much. If you applied caulking, you may need to sand down areas where the caulking overfilled. You may also want to scrape away at areas on the glass where adhesive or paint may have dried. Once everything is dry and ready to go, you can clean up the work area and place your blinds back on your windows. Immediately after you replace old weatherstripping, you will notice a big difference in temperature retention inside your home.
