Symptoms
- Visible rip or hole in the mesh
- Bugs getting in through the tear
- Mesh sagging or pulled loose from the frame edge
- Tear near a corner where it's stretched most
Likely causes
- CommonPhysical damage (pets, kids, storms, branches)Screens are thin and tear easily from claws, impacts, or being leaned on.
- CommonUV and age degrading the meshSun exposure makes screen material brittle over years.
- PossibleSpline (the rubber cord holding the mesh) drying out and crackingA failed spline lets the mesh pull loose and tear at the edges.
- Less commonFrame slightly bent, putting uneven tension on the meshA bent screen frame can stress the material until it splits.
What to do
- Pop the screen frame out of the window and lay it flat on a clean surface.
- Pry out the old spline from the groove around the frame using a flathead screwdriver.
- Remove the torn mesh and lay a new piece of screen material over the frame, overlapping the edges by an inch or two.
- Starting at one corner, press the new spline into the groove over the mesh using a spline roller, pulling the mesh taut as you go.
- Work around all four sides, keeping tension even so the mesh doesn't wrinkle.
- Trim the excess mesh close to the outside edge of the spline with a utility knife.
- Reinstall the screen in the window frame and check it sits flush and taut.

When to call a pro
Call a screen or window repair shop if the frame itself is bent or broken, since a damaged frame won't hold new mesh taut.
