No-See-Um Screen Installation in Jacksonville, FL

Neighborhoods near marshland, creeks, and wooded retention ponds deal with no-see-um season heavily in warmer months, and standard screen simply doesn't stop them. Homeowners who use their lanai in the evening — for dinner, relaxing, or watching the yard — are the ones who benefit most from making this switch.

The tighter weave that blocks tiny bugs also blocks more air. You'll notice less breeze coming through a no-see-um screened lanai compared to standard mesh, and it can also collect more pollen and dust since less is passing through the gaps. Most homeowners find the trade worth it for evening comfort, but it's worth knowing before committing the whole enclosure to this mesh.

No-see-ums are worst at dusk and dawn, low to the ground, and near standing water — which is exactly the environment inside a pool cage. Lower wall panels and the panels nearest the water usually deliver the most benefit, and many Jacksonville cages get 20/20 mesh on the walls with standard screen retained up high on the roof panels where airflow matters most.

On an attached lanai the priority is usually the seating area and the panels closest to the door, where people sit still at exactly the hours the gnats are active. If the whole enclosure is due for fresh mesh anyway, folding the upgrade into pool cage rescreening or screen enclosure rescreening costs less than a separate visit later.

In peak humidity and pollen season, tighter mesh means more visible film buildup that needs occasional rinsing to keep the view clear. During hurricane season, wind load on any mesh matters, and a tightly tensioned no-see-um panel performs similarly to standard screen in terms of frame stress.

Standard 18x14 mesh stops mosquitoes and leaves but not no-see-ums. If you're sitting in a screened enclosure at dusk still getting bitten by something you can barely see, the screen isn't damaged - the openings are simply larger than the insect. That's the entire reason this service exists.

It's most worth doing on properties near marsh, tidal creek, the Intracoastal, or any standing water, and on enclosures the family actually uses in the evening. If you rarely use the space after dark or you're inland with no water nearby, the airflow trade-off may not be worth it.

No-see-um mesh carries a modest per-square-foot premium over 18x14 fiberglass. On a small lanai the total difference is minor; across a full pool cage it becomes a line item worth deciding on deliberately.

A practical middle path many homeowners choose: tight weave on the panels around the seating area and standard mesh elsewhere. It costs less than a full upgrade and puts the benefit where people actually sit. Labor is the same either way, so the upgrade is cheapest when done during a rescreen you were already paying for.
