Choosing pool cage mesh in Lake Mary
Standard 18x14 fiberglass is the default mesh on nearly every pool cage in Lake Mary and the right choice for most of them. 20x20 no-see-um mesh earns its cost on lots backing Crystal Lake, Lake Emma, Lake Mary or a retention pond, because UF/IFAS puts biting-midge larvae in the moist margins of freshwater. Pet-resistant mesh belongs on door and lower panels only.
Four meshes, and who each one is for
| Mesh | Who it is for | Trade-off | Material cost |
|---|---|---|---|
| 18x14 fiberglass | The default on nearly every cage in the city | Cheapest per square foot, widest colour match to existing panels, easiest to source. Lets no-see-ums through. | $0.75 – $1.25 / sq ft (material, market estimate) |
| 20x20 “no-see-um” | Lots backing Crystal Lake, Lake Emma, Lake Mary or a retention pond | Tighter weave sold specifically against biting midges. Cuts airflow and light noticeably; costs a little more. | add roughly $10 – $20 per panel over 18x14 |
| Pet-resistant polyester | Door panels and the lower run where a dog leans and pushes | Vinyl-coated polyester, several times the tensile strength of fiberglass. Heavier, darker, more expensive — put it where the damage actually happens. | $1.50 – $2.50 / sq ft (material, market estimate) |
| Solar / privacy screen | West-facing lanais that cook from 3pm onward | Blocks a large share of solar heat gain at the cost of view and airflow. Usually one or two walls, not the whole cage. | $1.80 – $3.00 / sq ft (material, market estimate) |

Lake Mary is a freshwater city, and that decides the mesh
Most Florida mesh advice is written for coastal towns, where the pitch is salt corrosion and wind. Neither is the governing problem here. Lake Mary is built around freshwater: Liberty Park, the city’s own park at 455 N Country Club Road, sits directly on the shore of East Crystal Lake, and named lakes including Lake Mary, Lake Emma and Crystal Lake sit inside or against residential streets — before you count the retention pond in the back of nearly every subdivision built since 1985.
UF/IFAS identifies the moist margins of freshwater bodies, mudflats and moist soil as prime larval habitat for Culicoides biting midges, the insects everyone here calls no-see-ums. They are most active at dusk and dawn, which is exactly when a screened pool deck is worth having. Florida no-see-um activity is commonly described as running spring through fall.
So the mesh question in Lake Mary is not “what is best”, it is “what does your lot back onto”. A Timacuan lot on the Crystal Lake Preserve side, a Magnolia Plantation conservation lot and a Chase Groves lot on the retention pond are all candidates for 20x20. A Steeple Chase interior lot generally is not, and paying for tighter mesh there costs you airflow for nothing.
One honest caveat on the mesh count. The 20x20 weave is what the industry sells as no-see-um mesh, and it is unquestionably tighter than 18x14. But a primary UF/IFAS citation for the exact mesh count that actually excludes biting midges could not be verified for this page — the relevant EDIS publication returned an access error and a secondary summary attributing “16 by 16 mesh or smaller” to UF/IFAS could not be checked against the document itself. Anyone who quotes you a guaranteed exclusion figure without a source is guessing too.
Why the mesh fails here before the frame does
Seminole County publishes an Ultimate Design Wind Speed of 129 mph for Risk Category I, and the Florida Building Code permits screen enclosures to be designed to that category. The county sits below the 140 mph wind-borne debris region threshold and is not in the High-Velocity Hurricane Zone.
The practical result: a Lake Mary cage is engineered to a materially lighter wind load than a coastal one, and in a storm the frame usually survives while the mesh pulls out of the spline channel. That is why the standard post-storm job in this county is a partial or full rescreen rather than a rebuild — and why the spline specification on your quote is not a detail. Original spline on a 1980s or 1990s cage has hardened and shrunk; new mesh set into an old, undersized or debris-packed channel is the failure waiting for the next storm.
The other local variable: oak canopy
The City of Lake Mary requires a separate arbor permit application whenever trees are to be removed — the question is printed on the standard building permit application. That tells you what kind of city this is. Overhanging live oak and laurel oak limbs are the single biggest recurring cause of torn panels and algae staining on Country Club Road and the Markham Woods corridor, and a homeowner cannot simply cut the offending limb back without checking the arbor rules.
On a canopy lot, mesh choice will not save you. Trimming what you are permitted to trim, and accepting that roof panels there will be rescreened more often than the walls, will.

Mesh questions
What is the difference between 18x14 and 20x20 mesh?
The numbers are the weave count: strands per inch in each direction. 18x14 is the standard fiberglass pool cage mesh — 18 strands one way, 14 the other. 20x20 is a tighter, squarer weave sold as “no-see-um” mesh because the smaller openings are intended to keep out biting midges that walk straight through 18x14. The trade-off is real: a tighter weave reduces airflow and light and shows dirt sooner. Buy it for a reason, not by default.
What's the cheapest mesh option for a Florida pool cage?
Standard 18x14 fiberglass, at roughly $0.75–$1.25 per square foot of material by published Florida market estimates. It is also the right answer for most Lake Mary cages that do not back water. Where cheap goes wrong is buying the cheapest mesh for the door panel and the lower run, which is where a dog, a rake and a pool pole all live — those panels earn a heavier mesh even on a budget job.
How often should pool enclosure screens be replaced?
By condition rather than by calendar. The tells are chalky, brittle mesh that tears when you push it, spline that has gone hard and sits proud of the channel, and panels that have gone slack and drum loudly in wind. Lake Mary shortens that clock in two specific places: under oak canopy along Country Club Road and Markham Woods, where limbs abrade the roof panels, and on unshaded west-facing walls that take full afternoon sun.
