San Antonio's 100°F+ summers do brutal damage to standard fiberglass window screens. The vinyl spline that holds the mesh in place becomes brittle by year three, and the mesh itself sags from thermal cycling.
The permanent fix: aluminum-framed screens with stainless-steel mesh. They cost about 2x more upfront but last 15+ years instead of 4–5. For sliding patio screen doors, swap the plastic rollers for sealed bearing rollers — same logic.
Total cost for a typical 8-window San Antonio home: $480–$720 in materials, 4–6 hours of labor. Most of our SA handymen knock it out in one visit.
Pro tip: do this in February or March. Pricing on summer-emergency screen jobs in San Antonio jumps 35% from June through August.
