A quality custom screen is a long-term investment, but its lifespan depends heavily on the mesh, the frame and — most of all — how it's treated.
Typical lifespans
- Standard fibreglass mesh: 7–10 years before UV brittleness and sagging take over.
- Pet-resistant mesh: 10–15 years; the vinyl coating holds up well to both claws and sun.
- Ember-resistant stainless mesh: 20+ years; metal doesn't degrade the way fibre does.
- Aluminium frames: 15–20 years if kept clean; less if corroded by salt air or moisture.
What shortens a screen's life
Direct sun is the biggest killer — UV slowly turns fibreglass chalky and brittle. Salt air (near the coast) corrodes aluminium frames and hardware faster. Pets, hail, and being removed and reinstalled roughly each season all add wear. And a screen left dirty holds moisture that accelerates breakdown.
How to get the full years
- Hose screens down a few times a year; don't power-wash.
- Remove screens gently in winter if you store them, stacking flat.
- Upgrade to pet mesh where animals can reach.
- Choose UV-stable mesh on south- and west-facing windows.
When replacement beats repair
Once mesh is brittle or the frame corners are corroded, re-screening buys you a season or two at most. A full replacement with better mesh is the smarter long-term spend.
