How to Repair or Replace a Window Screen
A torn window screen lets in insects and makes a room feel unfinished. Replacing screen mesh in an existing frame is a simple 20-minute DIY job using a screen roll and a spline tool. It's cheaper than buying a pre-made screen.
Likely Causes
- 1Physical damage from pets, children, or impact
- 2UV degradation causing mesh to become brittle and tear
- 3Rust on older aluminum or steel frames
- 4Improper installation leaving the screen loose and prone to sagging
Cosmetic issue but allows insects and debris into the home. Easy to fix.
How to Fix It: Step by Step
- 1Remove the screen from the window
Most screens have pull tabs at the corners or sides. Pull them slightly and lift the screen out of the track.
- 2Remove old spline
The rubber spline holds the mesh in the frame groove. Find an end and pry it up with a flathead screwdriver or spline tool. Pull it all the way out. The mesh will release.
- 3Cut new mesh
Roll out screen mesh (fiberglass for residential use) 2 inches larger than the frame on each side. Cut with scissors.
- 4Align mesh over frame
Center the mesh over the frame and hold or tape it in place. Pull slightly taut but don't stretch it — screen should lay flat without pulling at the corners.
- 5Roll in the new spline
Using a spline roller, press the spline into the frame groove over the mesh. Start at a corner, work down one side, then around the frame. Maintain even tension in the mesh as you go.
- 6Trim excess mesh
Use a utility knife to trim mesh flush with the outer edge of the spline channel. Run the knife along the frame edge in one smooth pass.
