Screen Enclosure & Pool Cage Cleaning in Miami: the complete guide
What screen enclosure and pool cage cleaning actually involves
A pool cage or lanai enclosure is not one surface — it is three, and each one fouls differently and needs a different touch. There is the screen mesh (a woven fabric that stretches across every panel), the aluminum framing (hollow extrusions locked together with self-tapping screws), and the hardware and channels — the spline that holds the mesh in its groove, the door closers, the latches, and the fasteners. A proper cleaning has to read all three and treat them as the assembly they are, because what saves the screen can bleed rust from a screw if you skip a step, and what brightens the frame can burn brittle mesh if the dwell time runs long.
That is why this is a soft-wash job from top to bottom, never a pressure-washing job. The right method is chemistry plus a low-pressure rinse: a cleaning solution matched to the mesh and aluminum, applied under the pressure that would stress the fabric, given time to kill the mildew and algae at the root, then flushed out through the weave with a broad, gentle flow. The green comes off the screen. The black comes off the frame. Nothing on the cage is worse for the wash.
The Miami problems this service solves
South Florida is close to a worst-case climate for a screened enclosure, and each local force attacks a different part of the cage:
- Heat, humidity, and near-daily rain keep the mesh damp for hours at a time. Mildew and algae root into the weave — worst on the shaded and north-facing panels that never fully dry — and pollen and organic dust give the growth exactly what it needs.
- Coastal salt air (the marine corrosion zone rated ISO C5-M) etches and oxidizes the aluminum. Black streaking and white powdery corrosion creep down the uprights, and any water forced into the screw channels starts rusting the fasteners from the inside.
- Rust bleed from steel screws. The most common permanent-looking stain on a Florida cage is not on the aluminum at all — it is orange rust weeping out of a corroding self-tapping screw and running down the mesh below it. A surface rinse never touches it.
- Palm and tree litter. Fronds, leaves, and seed pods pile on the sloped screen roof, hold moisture, feed algae, and — left long enough — add real weight that sags and tears the panels.
The result is a cage that dims so gradually you stop seeing it, until one day the whole structure has gone gray-green and the light that used to pour over the pool is filtered and flat.
Step by step: what the process looks like
- Walkthrough and honest flag. Before anything gets wet, we look at the screen for brittleness, existing tears, rotted spline, and rust-stained mesh, and we tell you what will clean up and what is already too far gone. Sun-baked screen near the end of its life gets flagged so there are no surprises.
- Protect everything underneath. The enclosure sits directly over the pool, coping, deck, furniture, and planters. We pre-wet the surrounding plants, keep solution off the pool water, and control overspray so nothing beyond the cage gets coated.
- Apply and dwell. A cleaning solution matched to the mesh and aluminum goes on at low pressure and is given time to work. Dwell is what kills the organism at the root instead of knocking the surface layer off — the difference between a cage that stays clean and one that greens back in weeks.
- Rinse through the weave. A broad, low-pressure flow carries the loosened film out through the mesh rather than driving it in. We work the sloped or peaked screen roof and the tall uprights with soft-wash reach gear so the whole structure gets cleaned evenly, top to bottom, without dragging ladders against panels.
- Detail the frame and hardware. Uprights, cross-bars, the top rail, door frames, latches, and closers get cleaned, and the spline channels and screw lines are flushed so trapped grime and corrosion-feeding growth come out.
- Final rinse and re-wet. Plants, coping, and deck get rinsed again so nothing dries with a chemical film.
The surfaces and materials, and how each is treated
Screen mesh. Miami cages run a range of meshes and they do not all behave the same. Standard 18/14 fiberglass is the common pool-cage weave; tighter no-see-um mesh (20/20) blocks the tiny midges but clogs with film faster and dries slower; pet screen and heavier super-screen are thicker and tougher but still tear under pressure; and Florida Glass / privacy screen (a vinyl-laminated panel on the kick-plate row) has to be wiped and rinsed differently because solution sheets off it instead of passing through. All of it is cleaned with low-pressure solution and a gentle rinse the fabric can take.
Aluminum framing. Most cage frames are mill-finish or painted aluminum. The black streaking is a mix of organic mildew and surface oxidation — the mildew and much of the staining lift at low pressure. Deep oxidation etched into older unsealed aluminum can leave a faint shadow, and we will say so honestly rather than promise a like-new finish that cleaning alone cannot deliver.
Hardware and fasteners. Spline, door closers, latches, and the hundreds of screws holding the cage together are where trapped water and salt do their quiet damage. We flush the channels and rinse the hardware; where a screw has already rusted and bled onto the mesh, we treat the stain but tell you the source is a fastener that eventually wants replacing — a repair, not a wash.
What drives the cost
We never quote a flat number sight unseen, because the price of a cage cleaning is set by the structure, not a menu. The factors that move it:
- Size and number of screen sides — a small attached lanai versus a full free-standing pool cage with a peaked roof are very different jobs.
- Height and roof pitch — a two-story or high-mansard cage needs more reach equipment and time than a low single-slope.
- Condition — a lightly dimmed cage cleans fast; heavy algae, thick roof litter, and rust bleed take longer and more care.
- Access — furniture, landscaping, tight side yards, and screened rooms that open off the house all affect setup.
- Add-ons — cleaning the concrete or paver deck inside the cage is a separate hard-surface service priced on top.
The honest way to get a real figure is a look at the actual cage. That is what a free quote is for.
How often to clean it in Miami, and how to keep it clean
For most Miami pool cages, once a year keeps mildew and algae from ever taking hold. Heavily shaded or tree-covered enclosures do better on a roughly eight-to-nine-month cadence because they stay damp longer and green up faster. Between cleanings, a few habits stretch the results: knock the leaves and fronds off the screen roof before they mat down, keep the surrounding trees trimmed so panels get sun and airflow, and rinse the kick-plate band when you hose the deck. Many owners also time a wash for the spring, ahead of the June 1 start of hurricane season, so the cage is clean and clear before the storms — clean enough that you can actually see through it to spot loose panels before the wind finds them.
Screen cleaning versus pressure washing versus DIY
The single most important comparison is soft wash versus pressure wash, and it is not close. A rental pressure washer will get the green off — and take part of your enclosure with it. High PSI tears thin mesh, dents hollow uprights, and drives water into the screw channels where coastal salt turns it into corrosion. It also does not fix the problem: it knocks off the surface pigment and leaves the living organism behind, so the streaks return, often within a season. Soft washing removes the same growth at the root without any of that risk.
Cleaning is also not the same as restoration or rescreening. If your mesh is brittle, ripped, or rust-stained through, or the spline has dried out and popped, that is a repair — new panels, new hardware — not a wash, and we will tell you when you have crossed that line instead of blasting a screen that is already failing. A careful professional beats a rental machine here for one plain reason: knowing the difference between a cage that needs cleaning and a cage that needs a screen company is worth more than any amount of pressure.
Signs your cage needs cleaning now
- The screens have gone gray-green and the light over the pool looks dim or filtered
- Black streaks and white powder are creeping down the aluminum uprights
- Orange rust stains are running below screws on the mesh
- Mildew is spotting the panels, worst on the shaded and north-facing sides
- Leaves and palm fronds have matted on the screen roof and won't rinse off
- You are prepping a pool home for listing photos, where the cage frames every shot
If any of these describe your enclosure, the right move is a low-pressure soft wash by people who understand what is actually growing up there and how to remove it without harming the mesh, the frame, or the pool underneath.
