The Fort Myers pool cage is a humidity trap, and the deck is a different job
A screened pool enclosure in Fort Myers is really two surfaces that fail on different schedules. The cage itself - the aluminum frame, the screen mesh, the cage roof - sits in the fall line of the roof above it and in the shade of the lanai, so it stays damp long after the sun moves on. That trapped moisture is what lets mildew crawl up the mesh and blacken the frame on the side that never dries. The deck below is a separate problem: paver, travertine, or Kool Deck holds algae in its pores and joints, and the growth works in from the edges where the shade is deepest. Treating them as one job with one method is how a cage gets torn or a deck gets blasted. We soft wash the enclosure so the film lifts without stressing a panel or bending the frame, then clean the deck at a pressure matched to its surface - gentle on soft stone, firmer on solid concrete.
Why the shaded side of a Fort Myers cage goes black first
Walk any lanai in the Gateway communities or along the McGregor corridor and the pattern repeats: the north-facing elevation and the wall behind the pool equipment are where the black film shows up earliest. The sun dries the south and west faces, but the shaded planes hold the humidity that the Caloosahatchee air keeps feeding all year. On the aluminum frame that film is a mix of mildew and oxidized salt; on the screen mesh it is a living growth that can actually clog the weave and cut the breeze a cage is supposed to provide. Because the buildup is on the surface rather than in the metal, a low-pressure soft wash lifts it without the abrasion that would scratch the frame's factory finish and give the salt a place to bite. The result is a cage that looks new and a screen that lets the air through again.
Kool Deck, travertine, and pavers each need a different touch
The deck under a Fort Myers cage is rarely one material. Kool Deck - the textured, cool-to-the-touch topping common on older pools - is soft and porous, and high pressure will erode its surface and leave a rough patch that stains faster than the rest. Travertine is a natural stone with open pores and soft edges, and blasting it drives the algae deeper and can pit the face. Concrete pavers sit somewhere in the middle: sturdy enough for a firmer clean, but the joint sand between them is the weak point, and a hard wand will blow it out and leave the pavers shifting. We match the pressure and the chemistry to the surface, and we work the joints, screen tracks, and shaded corners by hand where the growth starts. The pool coping and the waterline tile get direct attention too, because that is where the algae that stains the deck actually begins.
What a proper Fort Myers lanai clean covers
- The screen mesh and frame. Soft-washed so the black film lifts without tearing a panel or bending the frame, and the cage roof rinsed as part of the same pass.
- The deck surface. Cleaned at a pressure matched to Kool Deck, travertine, or pavers, with the joints and shaded corners handled by hand.
- The pool coping and waterline tile. Treated directly, because that is where the algae that spreads across the deck starts.
- The pool water and plantings. Protected throughout - solution is kept out of the water and off the landscaping, and the enclosure is rinsed so nothing dries onto the frame.
Why the lanai is worth cleaning before the dry season
Most of Fort Myers' rain falls between June and October, and the wet months are exactly when a shaded cage grows fastest. A clean heading into the dry season leaves the space ready for the months when everyone is actually outside - the winter residents return, the holidays bring family to the lanai, and the pool gets used nearly every day. It is also the easiest time to schedule, because the afternoon storms that can cut a summer visit short are not a factor. For the same reason, a lanai that has gone a full wet season without a clean usually needs more than a quick rinse; the growth has had months to bond, and the honest fix is a proper soft wash rather than a stronger wand.
What a lanai clean will not fix
Being clear about the ceiling of the service saves a disappointing afternoon. A clean removes what is sitting on the surface and what is growing into it. It does not restore a material that has already failed. Screen mesh that has gone brittle in the sun will part under even a gentle wash, and it was at the end of its life before we arrived. Aluminum that has corroded through at a seam, or a frame that has pulled away from the slab, is a repair, not a cleaning. Rust that has been baking into white cage framing for several seasons usually lightens substantially rather than disappearing. None of that is a reason to skip the clean. It is a reason to know what you are buying, so the result is the one you were expecting when you agreed to the price.
How often a Fort Myers lanai needs it
There is no single calendar that fits every cage, and the honest benchmark is tied to the shade and the water rather than to the date. A cage on a heavily shaded lot in the Gateway communities, or one close to the Caloosahatchee where the salt load is heaviest, usually wants a clean every six to twelve months. A cage that sits in open sun and gets a breeze may stretch to a year or more. For the wet-season grow-in, the fall is the natural point to schedule, before the winter residents arrive and the lanai becomes the room everyone uses; that same timing also means the work is done ahead of the holidays rather than in the middle of them. The one date that trumps the weather is a deadline in an HOA letter - when a covenant has set a date, that date is what we work around.
