The door should easily come off with moderate force. Not all door styles will have a door handle overlapping the screen. If your screen door is on hinges, tap the hinge pins with a screwdriver to remove them and slide the door upward from the hinges.
Be careful when removing the splines. If they are still in good shape, you can reuse them. If you pierce the splines or damage them, throw them away and get new splines that have the same diameter as the old ones.
You can purchase a full roll of screening if you plan on replacing multiple screens in multiple doors. On average, most screen doors come in 2 standard sizes, either 32 in (81 cm) or 36 in (91 cm) wide. They often measure to 80 in (200 cm) high.
It’s okay if the screen is not perfectly centered since you’ll trim off the extra later on.
If you’re working alone, use pieces of tapes or clamps to hold the screen in place.
Doing this also helps prevent your screen from ripping during the process.
If you are replacing the splines, cut them to the length of the grooves on the door frame.
For a thorough hold, push the corners of the screen into place using a screwdriver. [10] X Research source
With a bit of maneuvering, you can easily put the door back on. If your door is on hinges, place the door back into your door frame, and place the hinge pins inside of the hinges. Tap them into place with the handle of a screwdriver.
