Window screens don’t last forever. They tear, loosen, and start looking sad after a few years of sun, wind, and weather abuse. If bugs are sneaking in or the mesh is flapping in the breeze, it’s time to replace it. The good news? You don’t need to call anyone. This is a beginner-friendly fix that takes less than an hour and only basic tools.
Here’s how to get it done.
What You’ll Need
-
New screen mesh (fiberglass is easiest to work with)
-
Spline (that’s the rubber cord that holds the screen in place)
-
Spline roller (a cheap tool, or you can improvise with something similar)
-
Scissors or utility knife
-
Flathead screwdriver or something to pry out the old spline
-
Measuring tape
Step 1: Remove the Screen Frame
Pop the whole screen frame out of the window. Most just slide or lift out. If yours is tricky, check for tabs or clips. Lay the frame flat on a table or the floor.
Step 2: Take Out the Old Spline and Mesh
Use your screwdriver to lift and pull out the rubber spline. It should come out in one piece, but don’t worry if it breaks. Toss the old screen mesh. You’re starting fresh.
Step 3: Measure and Cut the New Mesh
Roll out your new screen over the frame. Cut it so there’s about an inch of extra mesh on all sides. You want some slack so it fits snugly later.
Step 4: Install the New Mesh
Start on one side. Use your spline roller to press the new spline and mesh into the groove of the frame. The roller pushes the spline in and locks the mesh down. Work your way around the frame, pulling the mesh taut as you go. Don’t stretch it too tight—just firm and flat.
Step 5: Trim the Edges
Once the spline is fully in, use your utility knife to trim off the excess mesh. Cut right along the outer edge of the spline for a clean look.
Step 6: Pop the Frame Back In
Done? Nice. Snap the frame back into the window and admire your handiwork. No more bugs, no more sagging. Replacing a window screen is one of those satisfying, low-effort fixes that makes your home feel instantly better. No need to overthink it or overpay someone to do it for you. Once you try it, you’ll wonder why you waited so long.
