How Often Should You Replace Window Screens?

Window screens are one of those things most homeowners forget about until something goes wrong. A torn corner lets in flies. A faded, brittle mesh starts to look dingy from the street. Or maybe the frame just doesn't sit flush anymore and you're not sure why. The good news is that screens last a long time with minimal care. The bad news, especially in San Diego, is that sun, salt air, and Santa Ana winds shorten that lifespan more than most people expect.

Typical Screen Lifespan

Standard fiberglass mesh on aluminum frames typically lasts 7 to 10 years in moderate climates. In coastal San Diego neighborhoods like La Jolla, Pacific Beach, or Ocean Beach, that number drops to 5 to 7 years. The combination of UV exposure and salt-laden air breaks down mesh fibers faster, causes spline (the rubber gasket holding mesh in the frame) to harden and shrink, and can corrode aluminum frames over time.

Inland areas like El Cajon, Santee, and Poway generally see longer screen life since the salt exposure is minimal, though the intense summer sun still takes its toll.

6 Signs Your Screens Need Attention

• Visible holes or tears. Even small ones let insects in and get worse quickly.
• Mesh looks faded or chalky. UV-degraded fiberglass becomes brittle and tears easily.
• Spline pulling away from the frame. The rubber channel hardens with age and pops out of the groove.
• Bent or warped frame corners. Aluminum frames bend from handling, wind, or pets pushing against them.
• Screen doesn't sit flush in the window. The frame may have shifted or the window track has worn.
• Mesh is sagging or wavy. Loose mesh means the spline has lost tension. A rescreen will fix this.

Rescreen vs. Full Replacement

Not every worn-out screen needs a brand-new frame. If the aluminum frame is straight, has intact corners, and fits snugly in the window track, a simple rescreen is all you need. We strip out the old mesh and spline, roll in fresh material, and trim it clean. The whole process takes about 10 minutes per screen, and costs around $45 per window screen.

If the frame itself is bent, cracked, or corroded, a full replacement is the way to go. We custom-build a new frame to your exact window measurements, install your choice of mesh, and make sure it sits perfectly. Full replacement runs around $55 per window screen, only $10 more than a rescreen, so if your frames are questionable, it's usually worth the upgrade.

Extending Screen Life in San Diego

A few simple habits can add years to your screens. Rinse them with a garden hose two or three times a year to clear salt and dust buildup. Keep sprinklers from hitting screens directly because hard water deposits accelerate corrosion. And if you're replacing screens on a coastal home, consider upgrading to UltraVue or pet-resistant mesh, both of which hold up better than standard fiberglass in harsh conditions.

Most homeowners don't think about screens until there's a problem, and that's perfectly fine. When the time comes, a professional mobile rescreen is fast, affordable, and done right at your door. No trips to the hardware store required.
