Collier Screen Enclosures: Pool Cage Repair, Rescreening and Lanai Screens

Pool cage problems arrive in a predictable order and are usually cheapest to deal with early. Screen fails first, because mesh is the shortest-lived part of the structure. Then the fasteners, which in a coastal county corrode long before the aluminum they hold. Then the brackets and connections, and only after that the members themselves.

That order matters because the visible problem and the underlying problem are frequently different. A bay that has torn at the spline may have torn because the frame it is fixed to has begun to move, and rescreening it without establishing why treats the symptom. Equally, a cage that looks alarming with several panels gone is often structurally untouched.

The assessment worth having is what the structure needs rather than what the elevation looks like: whether the frame is square, whether fasteners have lost section, whether anchors into the deck and beam are still doing their job, and only then what the screening plan should be.

A pool cage is a larger version of the same job with one significant difference: height. The upper bays and the roof panels are where mesh fails first, because they take the most sun and the most wind, and they are the panels that cannot be reached from a ladder leaned against the frame.

Access is therefore part of the work rather than an afterthought. It also affects sequencing — it is normally cheaper to do the high panels while the access is set up than to return for them later, which is worth knowing when deciding how much of a cage to do at once.

Screen has a service life and it ends gradually. Sun degrades the mesh, it loses tension, and it starts to fail at the spline before it fails in the middle of the panel. A lanai that has begun to look slack is usually a season or two from tearing.

Whether to rescreen one bay or the lot is a straightforward calculation. A single storm-damaged panel is a single panel. Where mesh has aged uniformly, replacing everything at once costs less per bay and avoids an elevation that reads as patched, because new mesh beside old is visibly different even in the same specification.

The Florida Building Code allows enclosures to be designed so the mesh releases under load before the structure is overwhelmed, though the frame is still checked against code wind pressures with every panel in place. Once the screen releases, wind passes through the frame instead of pushing against it, and the cage that remains is carrying a fraction of the load it would otherwise see.

So a cage standing with its panels gone is usually the design working, not the design failing. What it does mean is that the frame took load during the event. Fasteners, brackets and anchor points are worth checking before new screen goes back on, because a frame that has been worked loose is not obvious from the deck and it will not be visible again once the bays are covered.
