The fear that keeps people from booking
A torn screen is a specific kind of bad outcome. It's not just a repair, it's an argument, because it's hard to prove a screen was fine before someone showed up with a machine, and it's hard for a company to prove it wasn't them. Nobody wants to be in that position, on either side of it, which is why this question comes up so often before anyone books a pool cage cleaning.
What actually tears a screen
It's almost never the water itself. It's pressure that's too high for the material, held too close, usually from a narrow nozzle that concentrates the spray into a tight, aggressive line instead of a wide fan. That kind of setup can cut a clean line through screen mesh in seconds, and it looks deliberate even when it isn't. The fix isn't complicated: don't run that kind of pressure or that kind of nozzle anywhere near the screen in the first place.
The actual number
A pool cage, the screens and the frame both, falls into the same exterior soft wash range as the rest of a home's exterior: 900 to 1200 PSI. That's a fraction of the 3000 to 4000 PSI used on concrete and pavers, and it's a wide fan pattern, not a narrow one. The whole approach is built around the fact that screen mesh and aluminum framing can't take what a driveway can, so they don't get treated like a driveway.
Why a wide fan matters as much as the number
PSI on its own doesn't tell the whole story, because the same pressure through a narrow tip and through a wide fan behave completely differently when they hit a screen. A narrow tip concentrates all that force into a thin line, which is what leaves a visible sweeping mark across a panel and can cut straight through the mesh. A wide fan spreads the same pressure across a much bigger area, so no single point takes the full force.
Distance does the same job. Backing off a few feet drops the force reaching the surface substantially. Between a lower pressure setting, a wide pattern and reasonable distance, there isn't much left that could tear a screen that wasn't already compromised.
Why the frame matters too
Most pool cage framing in this area is aluminum, not steel. It holds up fine at soft wash pressure, but it's part of the reason the approach stays gentle across the whole structure, not just the screens. Treating the frame and the mesh the same way, at the same pressure, is simpler and safer than trying to guess which parts can take more.
Why this matters more in Venice and Englewood
Both towns carry a lot of canal frontage and lanai living, which means cage density here is about as high as it gets in this market. Screens go grey and streaked from the same growth that hits roofs and walls, plus whatever blows in off the water. It's a job almost everyone with a cage eventually needs, which is exactly why getting the pressure question answered up front matters here more than in a lot of places.
What actually builds up on a cage out here
Cages in this area collect a mix of things, and it's worth knowing what's on yours before assuming it all comes off the same way. The grey-green film is the same organic growth that streaks roofs and walls, and that's the part a soft wash handles reliably. On properties near open water there's often a salt and mineral component layered in with it, which is why cages closer to the coast or on a canal tend to look worse faster than an identical cage a few miles inland.
Then there's whatever the surrounding vegetation drops on it. Pollen, leaf litter and the staining that comes from organic debris sitting wet on a screen for weeks. Most of that comes off. A screen that's had debris sitting on it through several rainy seasons can hold some discoloration, same as any surface that's gone a long time between cleanings.
Screens age on their own too
Screen mesh doesn't last forever regardless of whether anyone ever cleans it. Sun exposure makes it brittle over years, and an old screen that's near the end of its life can fail during a cleaning that a newer screen would have handled without any issue. That's not really the cleaning's fault, but it also isn't much comfort to whoever's looking at a torn panel.
This is the practical reason to flag an older cage before the work starts. If the mesh is well past its prime, it's better to know that going in, so nobody is surprised and everyone has the same expectations about what a cleaning is and isn't going to do to it.
What to do if you're still unsure
If a cage has any existing tears or weak spots, a photo before the job means those spots are already known about going in, not discovered after. That's a two-minute text, not an in-person walk-through.
Common questions
What if a screen tears during the job?
Photos before the work start means the condition going in is already documented, which is why that two-minute step is worth doing. It protects both sides from an argument nobody can win after the fact.
Can you clean a two-story cage?
Yes. Height mostly affects how long the job takes rather than whether it can be done, which is why a wide photo showing the full enclosure helps with the quote.
Will it get rid of the green on the frame too?
The frame and the screens both get cleaned, at the same pressure. Aluminum framing handles soft wash range fine.
