Pool Screen Enclosure Cost Calculator

---

A pool screen enclosure, also called a pool cage, usually costs $8 to $22 per square foot of footprint. Most backyard cages land between $8,000 and $35,000 installed. Size, wall height, roof style, mesh, and wind-code engineering set the price. Use the calculator above to estimate your cage from length, width, and options.

How much does a pool screen enclosure cost?

National consumer guides often quote $8 to $15 per square foot for a basic screen cage. Angi reports a typical 700-square-foot screen enclosure at about $5,600 to $10,500, and 2026 install jobs across enclosure types often fall between $7,051 and $18,831.

That $8–$15 figure is a footprint rate for a simple one-story screen cage. It is not what you pay for a two-story coastal cage with 20×20 mesh, a hip roof, and sealed engineering. Jobs that include extruded aluminum, roof framing, mesh, a door, labor, and permits more often land $15 to $22 per square foot. Large custom or high-wind cages run higher.

Project type	Typical installed range	What that usually means
Small patio / compact cage (about 240–450 sq ft)	$5,000 – $9,500	One-story, attached, standard 18×14 mesh
Standard backyard pool cage (about 700–1,000 sq ft)	$12,000 – $22,000	Mansard roof, one door, permits
Two-story or high-profile cage	$20,000 – $45,000	Taller walls, more aluminum, more labor
Coastal / high-wind engineered cage	Add about 15–30%	Heavier frame, tighter anchors, PE-sealed plans
Full rescreen of an existing cage	$1,500 – $4,500+	About $1.50 – $3.50 per sq ft of screen, if the frame is sound

Glass, polycarbonate, and motorized retractable enclosures are a different product. Screen cages are the budget outdoor option. Polycarbonate often runs $20 to $200 per square foot. Glass often runs $30 to $75 per square foot. Do not compare those quotes to a screen-cage number.

How to use this pool cage cost calculator

You need the outside footprint of the cage, not the water surface of the pool. Measure the deck edge where the posts will sit.

1. Enter length and width in feet, or switch to total area in square feet.
2. Choose attached to the home (three screen walls) or freestanding (four screen walls).
3. Set 1-story (8–10 ft walls) or 2-story / high profile (16–20 ft walls).
4. Pick the roof style: mansard, gable, hip, dome, or flat.
5. Pick the mesh: 18×14 fiberglass, 20×20 no-see-um, pet screen, or solar shade.
6. Set inland wind code or high-wind / coastal hurricane code.
7. Add screen doors, a kickplate, old-cage teardown, and permits / sealed plans.

The tool returns a midpoint, a low-to-high range, a cost per square foot of footprint, and a line-item split: aluminum frame, roof framing, mesh, doors, labor, and any add-ons.

Minimum size in the tool is 8 ft × 8 ft (64 sq ft). That matches a small screen room, not a swim cage.

Real numbers from this calculator

These are actual outputs for a one-story attached mansard cage, standard 18×14 mesh, inland wind code, one screen door, and permits on. No kickplate. No teardown.

Footprint	Screen surface	Midpoint	Range	Per sq ft of footprint
20 × 12 ft (240 sq ft)	662 sq ft	$5,000	$4,400 – $5,700	$20.83
30 × 15 ft, flat roof (450 sq ft)	986 sq ft	$8,047	$7,081 – $9,173	$17.88
40 × 20 ft (800 sq ft)	1,662 sq ft	$13,578	$11,948 – $15,479	$16.97
40 × 25 ft (1,000 sq ft)	1,960 sq ft	$16,591	$14,600 – $19,914	$16.59

Same 40 × 25 ft cage, changing one choice:

Change	New midpoint	Difference
Baseline (attached, 1-story, mansard, 18×14, inland)	$16,591	Reference
Switch to high-wind / hurricane frame	$19,341	+$2,750
Switch to 2-story / high profile	$21,813	+$5,222
Switch to freestanding (4 walls)	$16,940	+$349
Dome roof + solar mesh + hurricane frame + 2 doors + kickplate + teardown	$26,930	+$10,339

Notice the pattern. Height and wind code move the bill. A fourth screen wall barely does. Mesh and roof style change the bill more than people expect, because you buy mesh by surface area, not by the rectangle on the ground.

Footprint vs. screen surface: the quote trap

This is the number contractors use and homeowners miss.

A 40 × 25 ft attached cage is 1,000 sq ft on the ground. This calculator still has to cover about 1,960 sq ft of screen once you add walls and a mansard roof. Quote A at $14 per square foot of footprint and Quote B at $8 per square foot of screen can be the same job.

Ask every bidder:

• Is the rate on footprint or screen surface?
• Does the price include roof framing, spline, doors, anchors, labor, haul-off, and permit / engineering?
• What wind speed, exposure category, and code edition is the frame designed for?

If two quotes are thousands apart, they are usually measuring different things.

What drives the price

The following drives the price:

Size and height

Aluminum and labor are priced on footprint. Mesh is priced on walls plus roof.

This tool uses 9 ft walls for a one-story cage and 18 ft walls for a two-story cage. Going from one story to two on a 1,000 sq ft attached cage raises screen surface from about 1,960 sq ft to 2,721 sq ft, multiplies the frame rate by 1.45, and multiplies labor by 1.35. That is why a “same size” two-story cage is not a small upgrade.

Build time in the tool is 2–3 days for a typical one-story cage, 4–6 days if the footprint is over 1,200 sq ft or the walls are two-story, and 7–10 days over 2,000 sq ft. Weather, inspections, and deck repairs add time.

Attached vs. freestanding

An attached cage uses the house as one wall. The tool counts 65% of the full perimeter as screen wall. A freestanding cage screens all four sides.

On the 40 × 25 ft example, attached wall perimeter is about 84 linear feet. Freestanding is 130 linear feet. Extra mesh is real. Extra aluminum is smaller than most people think, because the roof still covers the same footprint.

The connection to the house is the weak point in storms. Cyclic-load tests on aluminum cages found that beam-to-host connections were critical to preventing collapse, and that K-type wall bracing outperformed cable bracing, while no bracing failed suddenly (Lewis, Jung, and Mtenga, 2013). If a bid skips host-structure hardware, bracing, or a gutter/fascia detail, it is not a complete bid.

Roof style

Mansard is the common U.S. pool-cage roof. The tool applies these roof-surface factors and roof-framing cost factors:

Roof	Screen-area factor	Framing cost factor	Why people pick it
Flat	1.02	0.90	Lowest cost, low pitch
Mansard	1.20	1.00	Common look, good wind shape
Gable (A-frame)	1.25	1.08	Matches a house gable
Hip	1.25	1.12	Four-sided slope, sheds wind
Dome / arch	1.30	1.20	Curved look, more framing

A cheaper roof is not automatically a weaker roof. A coastal hip roof with the right member sizes can beat a bargain mansard with skinny beams. The engineer’s span tables and your wind speed decide that, not the sketch.

Screen mesh

Mesh is a small line on the invoice and a big line in daily use.

Mesh	Calculator rate	Best use	Tradeoff
Standard 18×14 fiberglass	$0.85 / sq ft of screen	Everyday bugs, airflow, view	Tiny biting midges can still get in
20×20 no-see-um	$1.35 / sq ft of screen	Coastal no-see-ums and micro-insects	Less airflow, slightly darker view
Heavy-duty pet screen	$2.10 / sq ft of screen	Dogs, cats, toys, lower kick zone	Heavier look
Solar / privacy shade (about 80% shade)	$2.45 / sq ft of screen	Hot afternoon decks, glare, some privacy	Darker interior, more heat cut

18×14 means about 18 strands per inch one way and 14 the other. It is the usual pool-and-patio cloth. 20×20 is a tighter weave for no-see-ums.

Hole size, not the brand name on the roll, decides which insects get through. Greenhouse and crop-screen trials show that smaller openings exclude more pests, and that mesh shape also changes what gets through (Marshall and colleagues, Journal of Pest Science, 2022). Buy 20×20 because you have no-see-ums, not because it sounds “premium.”

Solar mesh is a comfort choice. In hot-climate field work, shade cut people’s thermal-sensation votes by about one point on a 9-point scale and raised comfort in every season except winter; tree shade and artificial shade performed about the same (Middel and colleagues, 2016). A pool cage is not a clinic, and it does not block all UV. It can make the deck usable at noon. You still need sunscreen, hats, and water.

Wind load and hurricane code

This is not an upgrade package you skip to save money in a coastal wind zone.

The calculator’s inland setting is a planning rate for frames commonly designed up to about 120–130 mph. The high-wind / coastal setting adds $2.75 per square foot of footprint to the aluminum line for heavier members, closer anchors, and hurricane-rated detailing (about 150–175+ mph design wind, depending on the site).

Florida treats screen enclosures as structures. Design pressures come from the Florida Building Code, including Section 2002.4 and the aluminum chapter, not from a salesperson’s “hurricane rated” sticker. Miami-Dade and Broward sit in the High-Velocity Hurricane Zone (HVHZ) and use stricter product-approval rules. Inland counties still have a mapped wind speed. Ask for the number on the plans.

A cage is usually designed with a lower importance factor than the house. It can fail at a lower wind speed than the dwelling, and broken aluminum can become debris. That is why bracing, host connections, and a permit set matter more than paint color.

Doors, kickplates, teardown, and permits

Add-on	What this calculator uses	Notes
Screen door	$375 each	Includes latch and closer in the model. Market doors often run $50–$500
Kickplate	$11.50 per linear foot of wall	16–24 in aluminum at the base. Stops mowers, pets, and dirt
Old cage teardown	$1.85 per sq ft + $450	Haul-off of the existing structure
Permits, engineering, sealed plans	$750, or $1,150 if footprint is over 1,500 sq ft	Required in most Florida and U.S. coastal cities

Leave the permit box on unless your building department has told you in writing that the job is exempt. A cheap cash bid with no plans is not a savings if the county red-tags it.

Self-closing, self-latching hardware is not a luxury on a pool cage. If a door sticks open, the cage is just a roof.

Pool cage vs. lanai vs. glass enclosure

People mix these names. The price only makes sense if the product is clear.

• Pool screen enclosure / pool cage. Aluminum frame, screen walls, screen roof. Covers the pool and often the deck. This calculator.
• Lanai / screened patio. Usually smaller, often attached, sometimes a solid roof with screen walls. Less aluminum than a full cage.
• Sunroom. Conditioned or at least weather-tight. Windows or glass. Not a screen cage.
• Glass or polycarbonate enclosure. Solid panels. Higher cost, more weather control, different engineering.

If you want bug control and debris control for a swim deck, a screen cage is the usual answer. If you want a dry room in January, you are shopping for glass or polycarbonate, not this tool.

What a contractor bid should include

Get at least three written bids from licensed, insured screen contractors. Same footprint. Same height. Same roof. Same mesh. Same wind speed.

A usable bid lists:

• Cage length, width, eave height, and peak height
• Attached or freestanding, and how it ties to the house
• Alloy, member sizes, and finish (extruded aluminum, powder coat color)
• Roof style and bracing type
• Mesh type, color, and manufacturer
• Number of doors, latch type, and self-closing / self-latching hardware
• Anchor type and host-structure connection
• Whether engineering, permit, and inspections are in the price
• Teardown, haul-off, and deck repair if the old cage comes down
• Warranty on frame, screen, and labor, written separately
• Proof of liability insurance and workers’ compensation

Walk the deck before you sign. Posts need a sound concrete edge. Uneven slabs, spalled coping, and buried utilities show up as change orders.

Safety, permits, and what a cage does not do

A screen enclosure can keep leaves, frogs, and many flying insects out of the water. It can add shade. It can make the deck usable in mosquito season. It is still an outdoor structure.

A cage is not automatically a legal pool barrier, and it does not replace watching children. Public-health guidance for backyard pools is a four-sided fence at least 4 feet high that separates the pool from the house, with a self-closing, self-latching gate. A Cochrane review of pool fencing found that fencing cut drowning and near-drowning risk (odds ratio 0.27), and that isolation fencing around the pool only beat three-sided fencing that still lets a child walk out of the house (odds ratio 0.17) (Thompson and Rivara).

If your city counts a screen enclosure as a barrier, it still has to meet that city’s latch height, door hardware, and inspection rules. Torn panels and propped-open doors fail those inspections. Nothing on this page is legal advice, medical advice, or a substitute for a building official or a licensed engineer.

Frequently asked questions (FAQs)

---

Technical Basis

The tool prices footprint with aluminum, roof, and labor rates, then adds mesh by wall-plus-roof area. Attached cages use 65% of perimeter as walls at 9 or 18 ft. Roof pitch factors are 1.02–1.30. Doors, kickplate, demo, and permits are optional. The range is 88–114% of the midpoint.

Disclaimer

This tool gives planning estimates only, not a bid, permit, or engineered plan. Costs vary with wind speed, deck condition, and labor. A screen cage does not replace required pool barriers or adult supervision. Confirm design, permits, and price with a licensed contractor and, where required, a registered engineer.
