Repairing a Screen
Have a small blemish on your screen? What about a bigger tear? No problem; we've got all the answers to help fix your screen.
Note: You'll need a piece of screen that's larger than the size of the frame, because the excess is trimmed to fit. While you're at the store, also buy a spline roller and new spline material that will fit the groove of your screen (you can use the old spline if it's not damaged). You could also use a putty knife instead of a spline roller so you don't need to buy a new tool.
Lay the new screen over the frame, making sure you have a couple inches of overlap on all four sides. Starting on the top edge, place the spline into the groove and press it in place with the spline roller or putty knife, letting the excess hang over. Check to make sure the screen material is not crooked.
