Step-by-Step Instructions
Step 1: Remove the Window Screen
- Carefully remove the screen from the window frame.
- Lay it flat on a clean, level surface.
Step 2: Remove the Old Spline
- Use a flathead screwdriver or spline removal tool to pull out the old spline.
- Remove the old screen mesh and clean the frame of any debris.
Step 3: Cut the Replacement Screen
- Measure the frame and cut a piece of replacement mesh slightly larger than the frame (about 1 inch extra on all sides).
Step 4: Install the New Screen
- Lay the screen over the frame, ensuring it overlaps evenly.
- Press the screen into the groove along one side, then work your way around.
Step 5: Roll in the Spline
- Using a spline roller, press the spline into the groove over the screen, securing it tightly.
- Keep the screen taut to avoid wrinkles.
Step 6: Trim Excess Screen
- Once the spline is fully seated, trim the excess screen material with scissors or a utility knife.
Step 7: Reinstall the Screen
- Place the screen back into the window frame and test the fit. Make sure it sits securely.
Tips for a Perfect Repair
- Keep the screen tight to prevent sagging over time.
- Fiberglass mesh is easier to cut and install than aluminum, especially for beginners.
- For large windows, ask a friend to help hold the screen while rolling in the spline.
- Consider replacing old or cracked spline along with the screen for a longer-lasting repair.
When to Replace Instead of Repairing
- Multiple tears or large rips
- Frame is bent or broken
- Spline groove is damaged
Replacing the screen entirely may be a better long-term investment in these cases.
