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

Along the St. Johns River corridor and the dozens of retention ponds scattered through Mandarin and Southside, standard 18x14 fiberglass mesh is basically a suggestion. No-see-ums push right through openings that size. Phifer's 20x20 super-screen — sometimes called no-see-um mesh — closes that gap down to roughly 1/20th of an inch while still passing enough air that the lanai doesn't turn into a greenhouse. Homeowners in 32257 who made this switch two summers ago stopped asking us to come back every season.

Jacksonville is a patchwork of housing eras. The Mandarin neighborhoods off Old St. Augustine Road (32223) run mostly 1985–2000 Florida ranch builds — concrete block, tile roofs, pool cages in ribbon-frame extruded aluminum that's held up but never got updated. Southside Estates and the older Baymeadows subdivisions (32216) have similar stock. Most of those cages went in with 18x14 fiberglass as the default. The frames are often still structurally fine; the mesh and sometimes the spline groove are what need attention. Jacksonville's east side tells a different story. Arlington (32225) and the neighborhoods around Fort Caroline Road sit close enough to the river that salt air is a real factor even without ocean frontage. Frame oxidation on 30-year-old cages shows up as white powder along the weld seams — mostly cosmetic until it works into the spline groove and makes screen replacement harder. San Marco and Avondale (32205) have older Florida-modern homes from the 1960s and 70s with box-frame cages that predate any HOA color requirements entirely. Down in the 32218 zip — New Berlin Road, Yellow Bluff — the lots run bigger, the cages run bigger, and the wetland pressure from Clapboard Creek means the upgrade conversation happens faster. Jacksonville's sheer geographic spread means one product spec doesn't fit the whole city.
