How To Repair A Window Screen
Window screens often take a beating from weather, pets, and general everyday use. Over time, they can’t help but tear, sag, or pop out of place. Instead of replacing the whole frame because of one rip, learning how to repair those rips will help your screens last much longer and save you money in the meantime. Whether it’s a small hole or a full re-screening, here’s how to get your window screen back in shape.
Check the Frame First
Before dealing with the screen itself, make sure the frame isn’t bent or damaged. A warped frame won’t hold the mesh tightly, which then leads to sagging or loose areas later on. If the corners are cracked or pulled apart, you can usually replace just those pieces. For minor bends, gently straightening the frame on a flat surface may be enough, but if the entire frame is warped or there’s a more severe bend, it’s probably just better to replace it altogether.
Remove the Damaged Screen
If the problem isn’t with the frame in you instead need to replace the screen itself, start by laying the screen frame on a flat, stable surface. Look for the spline, the rubber cord that holds the mesh in place. Use a flathead screwdriver or similar tool to lift one end and slowly pull it out. Once the spline is removed, the old screen will lift right off. Be careful not to bend the frame while doing this. If the spline is brittle or stretched, plan to replace it with new material.
Cut the New Mesh to Size
Place your new screen mesh (which is available at just about any hardware store) over the frame, leaving at least an inch of extra material on all sides. Fiberglass mesh is easier to work with than metal and tends to work well for most repairs. Keep the mesh straight and flat across the frame to avoid wrinkles. It doesn’t need to be perfect at this stage, but having enough overlap makes the next step easier and cleaner.
Install the New Screen with the Spline
Use a spline roller to press the new mesh into the groove around the frame, starting at one corner and working your way around. Keep steady pressure on the mesh as you roll in the spline. Take your time to avoid puckering or stretching. Once the spline is fully in, trim the excess screen using a utility knife held close to the groove. Be careful not to cut into the new mesh you just installed, though.
Check for a Tight Fit
Give the screen a gentle press and tug to make sure it’s firmly in place. There should be no sagging or looseness anywhere. If any corners feel soft or the mesh slips out, you’ll probably need to remove and re-roll that section. If everything feels secure, reinstall the screen into the window frame. Most modern screens snap or slide into place, but older windows may need pins or clips to hold them steady.
