There are a lot of videos on YouTube about how to replace a screen. Most of them that I have seen have a pane that only works once and then when you remove it, you replace it with rubber tubing that they sell from the store. They sell a special tools kit to pry the original pane off and some rollers and clips to get the screen back in nice by pushing the tubing into place without the groove. I recommend cutting a piece of wood to the exact spacing that the screen needs to maintained since making the screen tight can warp its profile and not fit correctly.
