Generally, screens should last from 10-15 years with regular maintenance. In fact, regular maintenance can add years to your screen’s life. To add time between screen replacements, wipe the frames every three to six months, keep the track free of dirt, and regularly inspect the mesh for holes or tears. If you hire window cleaners, ask them to inspect the screens before they replace them. If you take the time to maintain your screens, you can take more time between having replacement screens installed.
