Casper Screen Doors require minimal maintenance. We recommend that homeowners use a vacuum once a month to clean the bottom track of their screen door. This helps to eliminate any dust, pet hair or other particles that may have accumulated in the brushes on the bottom track. Casper Screens also recommends that the screen doors be retracted when not in use especially during cold, windy and wet winter months. To clean the screen mesh, use a sponge or towel and a mild solution of water and dish soap to wipe down the screen mesh of any dust. Never use WD-40 or other lubricants on our screen door components. If you are experiencing problems with the screen door, please give us a call.
