Steps to Repair a Screen. Find the end of the spline in the spline channel. Remove the damaged screen and clean the channel out. Roll the replacement screen over the frame and cut it using the scissors so that there is approximately one inch of excess on all size
Determine whether the torn screen is made of metal or fiberglass. Grab the torn area and feel it. Metal screening feels like metal and the loose strands are wire. Fiberglass screening feels smoother, more flexible and similar to plastic; it doesn't feel metallic at all.
Measure the rip or hole in the existing screen using a tape measure. Acquire a sizably larger replacement screen piece that matches the composition of the current screen, such as fiberglass replacement screen if the ripped screen is fiberglass. Be sure to match the color as closely as possible as well, since screen materials can vary from metallic silver to green.
Cut a rectangular or square piece of screening at least 1 to 2 inches larger on all sides than the damaged screen area. The larger the damaged area, the larger the overlap area need to be on the fresh piece you use as a patch.
Unravel and pull several strands off all sides of the perimeter of the patch; pull horizontal strands off the top and bottom and vertical strands off the sides. Bend the remaining strands at a right angle, facing the screen to be patched.
Press the angled strands of the patch into place over the torn area, then bend them flat onto the reverse side of the porch screen to secure the patch onto the existing screen. If the patch is made of fiberglass and doesn't stay put well on its own, apply a small amount of clear household cement to the strand edges after the patch is in place.
