Window Screens: lifespan, maintenance and replacement

Typical lifespan: 10–20 years (about 15 years).

Maintenance schedule

• Remove and rinse with hose — Annually (spring)
• Inspect mesh for tears or holes — Every 6 months
• Check frame corners for separation — Annually
• Replace spline if loose — As needed

Signs it needs replacing

• Multiple tears or holes in mesh
• Frame bent or warped beyond repair
• Corners separating
• Screen won't stay in window track
• Mesh stretched and sagging
• Oxidation or corrosion on aluminum frames

Tips

Fiberglass mesh is cheapest; aluminum is more durable; pet-resistant screen handles claws.
