Super Screen / No-See-Um Installation in Jacksonville Beach, FL

The tidal marshes lining the Intracoastal Waterway just west of 32250 push Culicoides biting midge populations hard from May through November — and on calm evenings those midges travel straight through standard 18x14 fiberglass mesh like it's not there. Phifer BetterVue panels installed a decade ago were never designed for no-see-um exclusion. Upgrading to 20x20 super-screen mesh stops that pressure without blocking the ocean breeze that makes a pool cage worth owning at the beach.

The block-construction homes between 3rd and 10th Avenue South in 32250 mostly went up in the 1980s and early 1990s — ribbon-frame cages, 2x2 extruded anodized aluminum, standard 18x14 at installation. Frames are still solid on most of them. The mesh is not. Direct Atlantic UV exposure sun-rots Phifer-grade fiberglass well before you see visible tears; a hand pressure test on any panel older than eight years usually tells the real story fast. North of Beach Boulevard, the homes along 1st Street North and the Sea Walk boardwalk area tend to run larger cages — some spanning screened patios that wrap both a pool and an outdoor kitchen. Those wider spans put more tension on the spline groove than a standard enclosure, and salt-air frame oxidation shows up faster than it does on inland Duval homes. Down in the South Jacksonville Beach corridor near Fletcher Park, a lot of homeowners converted 1970s beach cottages to full two-story builds with oversized lanai additions. The cage additions on those renovated properties often weren't matched to the original anchor bolt specs on older slabs — we see that mismatch regularly on estimates in the 32250 zip. The Seagate neighborhood just north of the Neptune Beach line has similar vintage cages; those frames are worth inspecting before committing to new mesh.
