How to Repair A window Screen

Repairing a window screen is a straightforward DIY project that usually takes less than 30 minutes.

What You’ll Need

• Replacement screen mesh (fiberglass or aluminum)
• New spline (the rubber cord that holds the screen in place)
• Spline roller tool
• Flat-head screwdriver
• Utility knife or scissors
• Measuring tape

Step 1: Remove the Screen

Carefully remove the screen frame from the window and place it on a flat surface.

Step 2: Remove the Old Screen

1. Use a flat-head screwdriver to pry up one end of the spline.
2. Pull the spline out around the entire frame.
3. Remove the damaged screen mesh.
4. Clean any dirt or debris from the frame channel.

Step 3: Cut New Screen Material

Lay the new screen over the frame, allowing at least 1-2 inches of extra material on all sides.

Step 4: Install the New Screen

1. Starting at one corner, press the screen into the frame channel.
2. Use the convex wheel of the spline roller to gently seat the screen into the groove.
3. Place the spline over the screen and use the concave wheel of the roller to press the spline into the channel.
4. Work your way around the frame, keeping the screen taut but not stretched too tightly.

Step 5: Trim Excess Material

Once the spline is fully installed:

• Use a utility knife to carefully trim the excess screen mesh along the outside edge of the spline.
• Be careful not to cut the new screen.

Step 6: Reinstall the Screen

Check for wrinkles or loose areas. If everything looks good, place the screen back into the window frame.

Common Problems & Fixes

Pro Tip

For most homes, fiberglass mesh is the easiest material to work with because it stretches slightly and is resistant to rust and dents. Aluminum screens are more durable but require more care during installation.
