How to Replace the Glass in a Screen Door


Replacing glass in screen doors, or more accurately in vinyl sliding doors, isn't complicated. However, it does take a little know-how and patience. Most vinyl screen doors have dual-paned glass, so even if your door is broken at least one pane is still probably stuck in the door. But it's not that hard to quickly and easily measure for a new pane of glass, remove the old, and install the new without calling a professional.

Things You'll Need

  • Razor blade Flat-blade screwdriver Tape measure Silicon tape
  • Cut the old glass free. Slide the razor blade along the edges of the entire pane of glass to cut the vinyl tape holding the glass in place. Next, find the plastic tabs located along the edge of the glass. These are the mounting tabs and hold the glass in place.

  • Slide a screwdriver under each of the plastic tabs and flip them up. Remove the tabs and then very gently slide the glass pane up and out of the door frame. Measure the length and width with a tape measure. Measure the width of the two panes as well. Order a new dual-pane glass insert for a sliding glass door from a local glass company or one of the companies listed in Resources below.

  • Sit the new pane of glass in the frame on top of the rubber bumpers in the bottom of the frame. Line the edges with vinyl tape and then slide into position in the frame. Reinstall all of the plastic mounting tabs and allow the door to dry for 24 hours in order to let the tape set up.

Tips & Warnings

  • You can also use silicone gel to mount the glass. However, it's harder to work with than vinyl tape.
  • Wear gloves and be extremely careful not to apply convex pressure to the new glass when handling it. This could break it.
