Florida and Gulf · screened pool cagesPool screen enclosure cost calculator
Safety first. Full aluminum pool enclosures are tall wind-bearing structures governed by the Florida Building Code and High-Velocity Hurricane Zone (HVHZ) engineering tables; a licensed aluminum specialty contractor, professional engineer, and municipal building inspector govern structural pool cage replacements.
This page is specifically for Florida and Gulf Coast homeowners who have a screened aluminum pool enclosure ('pool cage') over their swimming pool and lanai deck. Stop here if you are pricing an enclosed glass or insulated-roof room addition (the sunroom calculator), a solid solid-roof patio cover without a pool cage (the patio cover calculator), or a screened front porch (the covered porch calculator); swimming pool shells, pumps, and liners themselves are not covered on this site.
Across Florida and the Gulf in 2026, replacing 4–8 storm panels runs $350 to $1,100; a full rescreen runs $1.85 to $3.60 per deck sq ft ($1,480–$2,880 on 800 sq ft); 20x20 or polyester mesh adds $0.55 to $1.15/sq ft; a full aluminum cage rebuild runs $14 to $28/sq ft ($11,200–$22,400 on 800 sq ft); doors run $175 to $375; stainless fasteners/cables add $350 to $850; and PE permits add $450 to $1,450.
For an 800-square-foot pool deck footprint needing a full rescreen with standard 18x14 mesh, 2 new screen doors, and a stainless fastener/cable refresh, expect $2,180 to $4,480.

Key facts at a glance
- A complete pool enclosure rescreen (removing old mesh and brittle spline and rolling new 18x14 fiberglass screen across all roof and wall bays—roughly 1.7 to 2.0 sq ft of screen surface per 1 sq ft of deck footprint) runs $1.85 to $3.60 per square foot of deck footprint.
- Upgrading from standard 18x14 charcoal fiberglass mesh to tight 20x20 'no-see-um' midge mesh or heavy vinyl-coated polyester ('Super Screen'-style) mesh adds $0.55 to $1.15 per square foot of deck footprint.
- Demolishing a storm-collapsed pool cage and erecting a new code-engineered extruded-aluminum enclosure (6063-T6 / 6005-T5 alloy under Florida Building Code Chapter 20 & AAF Guide) runs $14.00 to $28.00 per square foot of deck footprint, plus $450 to $1,450 for PE wind-load engineering, permit, and scrap haul-away.
- Replacing rusty carbon-steel screws and deck concrete Tapcons with 300-series/bi-metal stainless fasteners and tensioning diagonal aircraft-cable wind braces ('re-furbishing' the frame during a rescreen) runs $350 to $850, and new heavy-duty aluminum screen doors with kickplates and pneumatic closers run $175 to $375 each.
- In Florida and Gulf wind markets, standard homeowners policies often exclude aluminum pool cages and screen mesh from windstorm coverage unless the homeowner purchases a specific 'Screened Enclosure' endorsement; this page never publishes a 'typical' buyback dollar cap without a state-regulator source—read your policy declarations page.

Pool screen enclosure: every numbered part explained
The drawing above has 9 numbered parts, from Extruded aluminum arches & uprights to Permit, engineering and haul-away. Each card zooms in on one part, says what pushes its price up or down, and what to check on a written quote. After you run the calculator, the parts in your scope show their dollar figure.
1 Extruded aluminum arches & uprights
$14.00 – $28.00 per sq ft of pool-deck footprint (full cage rebuild)
Florida and Gulf Coast pool cages are built from heavy 2x4, 2x6, to 2x10 structural aluminum extrusions (typically 6063-T6 or higher-strength 6005-T5/6061-T6 alloy in bronze or white baked enamel) engineered under Florida Building Code Chapter 20 to withstand 130 to 180 mph wind zones. If a hurricane kinks, twists, or collapses the main roof arches, you cannot safely bend hollow aluminum back straight—the cage must be demolished and rebuilt ($14–$28 per sq ft of deck footprint).
What moves it: Mansard vs dome vs gable roof style, wider 'picture-window' clear-view spans (which require heavier 2x8 or 2x10 beams), and coastal wind-speed zone.
On the quote: If you are rebuilding a collapsed cage, ask what alloy and beam size (e.g. 2x6 vs 2x8) are required to eliminate intermediate posts for a wider 'picture window' view.
2 Screen mesh panels & flat spline
$350–$1,100 (4–8 panel patch) | $1.85–$3.60/deck sq ft (full rescreen) | +$0.55–$1.15/sq ft (20x20 or poly)
Intense Florida UV sunlight bakes standard fiberglass screen mesh and vinyl spline brittle in 8 to 12 years. Once panels tear in normal summer squalls, patching individual bays ($350–$1,100 for 4 to 8 panels) becomes a losing battle. A complete rescreen ($1.85–$3.60 per deck sq ft, or $1,480–$2,880 on 800 sq ft) strips every roof and wall panel and rolls fresh 18x14 fiberglass or upgraded 20x20/polyester mesh (+$0.55–$1.15/sq ft).
What moves it: Standard 18x14 charcoal fiberglass vs 20x20 no-see-um midge mesh vs heavy vinyl-coated polyester mesh.
On the quote: Notice how contractors price full rescreens: they either quote per square foot of your flat pool deck footprint ($1.85–$3.60/sq ft) or per actual square foot of screen fabric (which is roughly 1.8x the deck area).
3 Stainless steel anchors & fasteners
$350 – $850 (bundled with diagonal wind-cable package)
Many pool cages built before 2012 were assembled with zinc-plated carbon-steel tek screws and concrete Tapcon deck bolts. Pool chlorine vapor and coastal salt air corrode carbon-steel bolt heads until they snap off inside the aluminum upright, allowing the cage to lift off the concrete deck during a storm. During a full rescreen, upgrading rusted base anchors and bracket screws to 304/410 stainless or coated bi-metal fasteners ($350–$850 with cables) extends the frame's life by 15+ years.
What moves it: How many original concrete deck Tapcons and corner gusset screws have rusted heads or white galvanic corrosion powder.
On the quote: Never spend $2,500 rescreening a 12-year-old pool cage without having the crew replace rusty base-plate Tapcons and corner bracket screws at the same time.
4 Diagonal wind cables & K-braces
Included in the $350 – $850 fastener & cable refurbishment package
Look at the end walls and corner bays of your pool cage: diagonal 1/8-inch vinyl-coated galvanized or stainless steel aircraft cables (or rigid aluminum K-braces) transfer lateral hurricane wind loads down into the concrete deck. Over time, turnbuckles loosen or rusty eye-bolts pull out. Replacing frayed cables and tensioning turnbuckles during a rescreen keeps the aluminum frame square so roof panels do not pop their spline in high gusts.
What moves it: Replacing frayed galvanized cables and rusted eye-bolts with stainless steel cables and turnbuckles.
On the quote: Pluck the diagonal wind cables on your pool cage—if they sag loosely or have rusty eye-bolts at the deck, include cable replacement in your rescreen contract.
5 Screen doors, kickplates & closers
$175 – $375 per door installed
Pool cage doors take more daily abuse from kids, pets, lawn crews, and wind gusts than any other part of the enclosure. A heavy-duty replacement aluminum screen door ($175–$375 installed) includes three heavy hinges, a 16-inch aluminum kickplate at the bottom to stop lawn equipment and dogs from punching through the mesh, a bottom nylon bug sweep, a positive latch handle, and an adjustable pneumatic door closer with a storm chain.
What moves it: Standard 36x80-inch single doors versus wide 48-inch lawn-equipment doors or double French screen doors.
On the quote: Always install a top storm chain alongside the pneumatic closer on every pool cage door so a sudden wind gust cannot whip the door backward and rip the hinges.
6 Super-gutter & house fascia header
Inspected on rescreen; replaced in full cage rebuild ($14–$28/sq ft)
Where the pool cage roof meets your house, a heavy structural extruded-aluminum trough called a 'super-gutter' (typically 5x5 or 7x7 inches) bolts directly into the house rafter tails or concrete bond beam to carry both the roof rainwater and the structural load of the pool cage roof arches. If your house has rotted wood fascia behind the super-gutter, repair the wood sub-fascia first (see the soffit and fascia calculator) before attaching a new cage.
What moves it: Condition of the wood sub-fascia and rafter tails on the house eave where the super-gutter bolts in.
On the quote: If you are replacing your house roof (the roof calculator) and rescreening your pool cage in the same year, do the roof and fascia work first so roofers do not drop shingles through new screen.
7 Concrete pool deck footer condition
Inspected before full cage rebuild (link concrete leveling calculator)
Florida Building Code requires the upright columns of a new pool screen enclosure to anchor into a thickened concrete perimeter footer or concrete stem wall—a thin 3.5-inch unreinforced patio slab edge can crack and spall when high-wind anchor bolts pull upward. If your existing pool deck has settled or cracked at the perimeter, budget for concrete leveling calculator or poured concrete footers before erecting a new $15,000+ aluminum cage.
What moves it: Whether the existing pool deck already has an engineered 8x12-inch thickened perimeter beam or requires new concrete footers.
On the quote: When getting full cage rebuild bids, ask whether the municipal inspector will accept your existing concrete deck edge or require new poured footers.
8 Hurricane pool-cage insurance endorsement
Check your policy declarations page & hurricane deductible calculator
In Florida and along the Gulf Coast, standard homeowners policies rarely cover screen enclosures like a house roof. Many carriers exclude pool cages and screen mesh from windstorm coverage unless you buy a 'Screened Enclosure' endorsement—and even then, some pay only for the aluminum frame (often at ACV) and exclude torn screen fabric unless the frame collapses. Read your declarations page carefully.
What moves it: Whether your policy includes a Screened Enclosure endorsement, whether it covers screen mesh or frame only, and your percentage hurricane deductible.
On the quote: Before filing a hurricane claim solely for a $2,800 pool rescreen, run your percentage hurricane deductible in the hurricane deductible calculator—your deductible alone may be $6,000 to $12,000.
9 Permit, engineering and haul-away
$450 – $1,450 on a rebuild
A full cage rebuild needs wind-load engineering and a building permit in most coastal counties, plus haul-away of the old aluminum. A straight rescreen usually needs neither, which is why this line appears only on rebuilds.
What moves it: Whether you rescreen or rebuild, and your county's wind rules.
On the quote: Confirm the engineering, permit and haul-away are in the rebuild price.
Project photo guide
Pool screen enclosure in photos: spline, anchors and the door
Pool enclosure projects range from rolling fresh mesh into sound tracks to bolting up a new aluminum frame. These four scenes show a bronze pool cage over a Florida lanai, rolling flat vinyl spline, upgrading rusted base bolts to stainless steel, and a new screen door.
How the job works in 3 key stages
All three step images are AI-generated illustrations for explanation. Not a site inspection, bid, or coverage decision.
Step 01Re-bolt and tension
Rusty carbon-steel deck bolts are swapped for stainless steel and the diagonal wind cables are tightened so the frame stays anchored in gusts.
Why it matters: Upgrading rusty carbon-steel deck bolts to stainless steel and tightening diagonal wind cables ($350–$850) keeps the frame anchored in tropical gusts.
Step 02Rescreen with new spline
New fiberglass or no-see-um mesh is rolled taut into every bay with fresh UV-resistant flat spline after the old brittle spline is pulled out.
Why it matters: A complete rescreen replaces both the charcoal mesh and the brittle flat vinyl spline across every roof and wall panel.
Step 03Replace the screen doors
Worn screen doors are replaced with new aluminum units with kickplates, bug sweeps and pneumatic closers.
Why it matters: Replacing worn aluminum screen doors with new kickplates, bug sweeps, and pneumatic closers runs $175 to $375 per door.

Three worked scenarios with full arithmetic
Scenario 1: complete rescreen + 2 doors + stainless fastener/cable package on an 800 sq ft deck (worked example, 1.00x)
A Florida homeowner with an 800-square-foot pool deck inside a straight 11-year-old aluminum cage (footprint_sqft = 800, scope = full_rescreen) chooses standard 18x14 charcoal fiberglass mesh (mesh = std_1814), replaces 2 corroded screen doors (doors = 2), and upgrades rusty deck Tapcons and diagonal wind cables (fasteners_cables = yes, permit_eng = no).
- Complete Pool Cage Rescreen (800 deck sq ft × $1.85–$3.60/sq ft): $1,480 – $2,880
- 2 New Aluminum Screen Doors (2 × $175–$375): $350 – $750
- Stainless Steel Fasteners & Diagonal Wind Cables: $350 – $850
- Central / Southwest Florida Baseline Total (1.00x): $2,180 to $4,480
Scenario 2: post-storm partial repair of 6 blown-out roof & wall panels only (1.00x)
After a summer squall tears 6 screen panels on a 4-year-old pool cage whose frame and doors are otherwise like new (scope = partial_panels, doors = 0, fasteners_cables = no, permit_eng = no).
- Partial Storm Panel Replacement (4 to 8 panels): $350 to $1,100
Scenario 3: full hurricane-collapsed aluminum pool cage rebuild on an 800 sq ft deck with polyester mesh (1.00x)
A hurricane collapses an older pool cage over an 800-square-foot pool deck (footprint_sqft = 800, scope = full_cage). The homeowner builds a new FBC code-engineered aluminum cage with upgraded heavy polyester screen (mesh = upgrade_mesh), 2 new doors (doors = 2), stainless fasteners and cables (fasteners_cables = yes), and PE engineering plus municipal permit (permit_eng = yes).
- Full Extruded-Aluminum Pool Cage Rebuild (800 sq ft × $14.00–$28.00/sq ft): $11,200 – $22,400
- Upgraded Polyester / No-See-Um Mesh (800 sq ft × $0.55–$1.15/sq ft): $440 – $920
- 2 New Aluminum Screen Doors (2 × $175–$375): $350 – $750
- Stainless Fasteners & Wind Cables: $350 – $850
- PE Wind-Load Engineering, Permit & Old Cage Haul-Away: $450 – $1,450
- Central / Southwest Florida Baseline Total (1.00x): $12,790 to $26,370
Decision table: partial panel repair vs full rescreen vs full cage rebuild
| Condition of Your Pool Enclosure | Best Scope | 2026 Cost (800 Sq Ft Deck) | Why |
|---|---|---|---|
| Screen is <6 years old; 1 to 8 panels tore in a storm; frame is straight | Partial Panel Repair | $350 – $1,100 | Remaining mesh still has 5+ years of UV life |
| Screen is 8–12+ years old, chalky, or tears easily; aluminum beams are straight | Full Rescreen + Stainless Upgrade | $2,180 – $4,480 (w/ doors & bolts) | Patching brittle 10-year-old screen wastes money on repeat ladder fees |
| Main aluminum roof arches or uprights are bent, twisted, or collapsed | Full Aluminum Cage Rebuild | $12,790 – $26,370 (complete) | Kinked hollow structural aluminum loses wind-load rating and cannot be straightened |
Screen mesh comparison: 18x14 fiberglass vs 20x20 no-see-um vs polyester
| Mesh Type | Cost Adder (800 Sq Ft Deck) | Expected Florida Lifespan | Best For |
|---|---|---|---|
| 18x14 Standard Fiberglass | Base ($0 extra) | 7 to 10 years | Normal suburban lots; best airflow and outward visibility |
| 20x20 No-See-Um Fiberglass | +$440 to $920 | 8 to 11 years | Coastal marshes, mangroves, and canals with tiny biting midges |
| Vinyl-Coated Polyester ('Super' Mesh) | +$440 to $920 | 12 to 18+ years | Golf course lots, pets, falling oak branches, and maximum tear resistance |
Quote checklist: 8 items to verify in a pool cage bid
- Deck Footprint vs Screen Surface Sq Ft: Confirm whether the contractor is quoting by flat pool-deck square footage ($1.85–$3.60/sq ft) or total roof-plus-wall screen fabric square footage so you compare apples to apples.
- US-Made UV-Inhibited Screen & Flat Spline: Cheap imported spline turns rock-hard and splits within 3 years in Florida sun.
- 304 / 410 Stainless or Bi-Metal Fasteners: Verify that all deck base-plate Tapcons and corner bracket screws are corrosion-resistant stainless steel.
- Diagonal Wind-Cable Tensioning: Are all four corner bays fitted with tight aircraft-cable wind braces?
- Super-Gutter & House Fascia Check: Did the estimator inspect the house wood fascia behind the super-gutter (see the soffit and fascia calculator)?
- FBC Wind-Speed Engineering (Full Rebuilds): Does a full cage rebuild include stamped PE drawings for your exact wind-speed contour (140–180 mph)?
- Door Hardware Completeness: Do new doors include 16-inch kickplates, pneumatic closers, top storm chains, and bottom bug sweeps?
- Insurance Deductible Math First: Before signing an insurance-contingent contract after a storm, run hurricane deductible calculator.
Typical rescreening & cage rebuild timeline
- Partial Panel Repair (4–8 Panels): 2 to 4 hours.
- Complete Rescreen + Doors + Fastener Refurbishment (800 Sq Ft Deck): 1 to 2 days on site.
- Full Aluminum Cage Rebuild: 3 to 6 weeks for PE engineering and municipal permit approval + 3 to 5 days on site for old-cage demolition and erecting the new enclosure.
Worked example
A Florida homeowner with an intact aluminum pool cage covering an 800-square-foot pool deck footprint (footprint_sqft = 800) hires a screen contractor for a complete rescreen (scope = full_rescreen) using standard 18x14 fiberglass mesh (mesh = std_1814), replaces 2 corroded aluminum screen doors with kickplates (doors = 2), and adds the stainless steel fastener and diagonal wind-cable refurbishment package (fasteners_cables = yes, permit_eng = no) at the 1.00x Central/Southwest Florida baseline.
The default job, line by line
Worked example| Line item | National planning range |
|---|---|
| Complete pool cage rescreen | $1,480 – $2,880 |
| Two new aluminum screen doors w/ kickplates & closers | $350 – $750 |
| Stainless steel fastener upgrade & diagonal wind cables | $350 – $850 |
| Total before regional adjustment | $2,180 – $4,480 |
Midpoint about $3,330. These are the calculator's default inputs, so pressing the button above at the national region reproduces this table.
Does insurance cover a pool cage?
In Florida and Gulf Coast windstorm markets, screened pool enclosures ('pool cages') are treated differently from the main house on almost every homeowners insurance policy. Standard base policies routinely exclude aluminum pool enclosures and screen mesh from hurricane and windstorm coverage altogether, or pay only Actual Cash Value (ACV) on structural aluminum framing while excluding screen fabric unless you purchased a specific 'Screened Enclosure' (or 'Hurricane Screened Enclosure Buyback') endorsement. Even when you carry that endorsement, two rules control your payout: (1) the endorsement carries its own separate dollar limit printed on your declarations page, and (2) hurricane damage is still subject to your percentage hurricane deductible (the hurricane deductible calculator), which is often $5,000 to $15,000+. Standalone rescreens usually fall below hurricane deductibles.
What this page will not claim
- This page does not quote a 'typical' insurance buyback dollar cap: Endorsement limits depend entirely on your carrier and declarations page.
- This page does not price swimming pool shells, pool resurfacing, pumps, or heaters: Only the screened aluminum pool enclosure is priced here.

Frequently asked questions
Why do two pool screen contractors give me completely different square-foot numbers for the same pool cage?
Because one contractor is measuring your flat pool deck footprint (for example, 25x32 feet = 800 sq ft at $1.85 to $3.60/sq ft) while the other is measuring the total 3D screen surface area of the upright walls plus the sloped mansard or dome roof panels (which is typically 1.7 to 2.0 times the deck footprint, or ~1,450 sq ft at $1.00 to $1.95/sq ft). Both methods reach the exact same $1,480 to $2,880 bottom line.
Does Florida homeowners insurance cover a pool cage blown down or torn by a hurricane?
Only if your policy includes coverage for screened enclosures—often via an optional 'Screened Enclosure' endorsement listed on your declarations page—and only after your total covered hurricane loss exceeds your percentage hurricane deductible (the hurricane deductible calculator). Furthermore, many policies exclude torn screen mesh unless the aluminum frame itself is structurally damaged.
Should I pay extra for 20x20 No-See-Um mesh or heavy polyester screen when rescreening my pool cage?
Choose 20x20 No-See-Um mesh (+$0.55 to $1.15 per deck sq ft) if you live near coastal mangroves, marshes, or brackish canals where tiny biting midges pass right through standard 18x14 screen; note that the tighter weave slightly reduces airflow by ~10% to 15%. Choose heavy vinyl-coated polyester screen (+$0.55 to $1.15/sq ft) if you want a 12-to-18-year lifespan that resists golf balls, pet claws, and flying twigs.
What is a pool cage 're-furbishment' vs a simple rescreen, and is the stainless bolt upgrade worth $350 to $850?
A basic rescreen only replaces the mesh and vinyl spline. A refurbishment adds $350 to $850 to replace rusted carbon-steel concrete Tapcon anchors along the pool deck, swap corroded structural bracket screws for 300-series/bi-metal stainless fasteners, and replace frayed diagonal wind-brace cables. On any cage over 10 years old, replacing rusted deck bolts prevents the entire cage from lifting in the next storm.
Can a contractor straighten bent aluminum pool cage beams after a tree limb or hurricane hits them?
You can replace individual bolt-in horizontal purlins or a single damaged wall post, but once the main load-bearing extruded aluminum roof arches are kinked, buckled, or twisted out of plumb, structural building codes (Florida Building Code Chapter 20) prohibit bending hollow tempered aluminum back into shape because the metal work-hardens and cracks. If main arches collapse, a full cage rebuild ($14 to $28/deck sq ft) is required.
Should I cut slits in my lower pool screen panels or take the doors off before a hurricane hits?
Never cut your screen panels, and ask your contractor before removing doors. Modern engineered pool cages are designed with diagonal wind cables to act as a tensioned structural unit; removing doors can sometimes create internal wind pressurization against the house sliders, while old brittle screen is actually designed to blow out of its spline track before the wind load overturns the aluminum beams.
