A pool cage is a different animal from a screen room — it's a tall, clear-span aluminum structure that has to span an entire pool deck, carry serious wind uplift on its mansard or hip roof, and often serve as the pool's legal safety barrier. We prepare the signed and sealed engineering Polk County requires for pool enclosures across Lakeland, Davenport, Winter Haven and Haines City, and submit it for you.
Polk County anchors the fast-growing Four Corners / I-4 corridor, and Davenport in particular has seen a wave of new-home and new-pool construction. Almost every one of those pools ends up under a cage — and a pool enclosure is the most demanding of the aluminum structures we engineer. Unlike a small screen room, it spans wide and stands tall over the pool and deck, so its mansard, hip or gable screen roof and its super-gutter connection back to the house have to be sized for real loads, not a catalog detail. From Lakeland to Winter Haven to Haines City, we design the cage for your exact lot.

A pool cage is permitted as a structure, and with the volume of new pools moving through Polk County's building department, an incomplete package sits. Signed and sealed, site-specific engineering is what keeps yours out of the correction cycle.
Polk County requires drawings and wind-load calculations for the specific cage, sealed by a Florida PE. Column sizes, beam spans, the roof frame and every anchor must trace back to the calculated pressures — a generic manufacturer sheet is not site-specific engineering.
Polk County and its municipalities take applications through their online permitting portals; where paper is still used, two signed and sealed sets are standard. We prepare the package for whichever route your jurisdiction uses and file it for you.
Design wind speed is typically around 139 mph (Vult), confirmed per site during design. A pool cage stands well above deck level, so its tall walls and screen roof see high C&C uplift at 139 mph — precisely where undersized connections fail in a storm.
Where the cage acts as the pool's safety barrier, its walls, screen and self-latching access door must meet Florida's residential pool barrier rules. The package also ties the columns into the pool deck or new footings — the base connection that resists the roof's uplift.
Our pool enclosure package starts at $2,000 and includes engineering, wind-load calculations, the PE seal, and submission to Polk County or your municipal building department. Same-day proposal on request.

Your property survey and a set of photos of the pool, deck and house wall tell us everything a site visit would: the deck footprint, where columns land, and where the super-gutter ties into the fascia. That's how out-of-state owners of Davenport and Four Corners pool homes get a cage permitted without flying in.

Pool cages are the projects where cutting corners on engineering shows up first — a wide roof at 139 mph is unforgiving. In a market adding pools this fast, contractors send us their cage work because the drawings clear review the first time, and the engineer who seals the package is the person who answers the phone.
Clear-span mansard and hip roofs, tall corner columns, super-gutter tie-ins and screen-wall barriers are our routine work — not an occasional detail. We size the frame and every connection from the actual calculated loads for your Polk County lot.
Pool builders working the Davenport and Four Corners boom send us cage after cage because the process repeats: same flat rate, same 5–7 day turnaround, same first-pass quality, so they can schedule the screen crew with confidence.
Engineering, seal, county submission and every reviewer-requested revision are in the price. If Polk County asks for a change on your cage, resolving it is our job — not a new invoice.

Engineering is done in 5–7 business days. County review varies with Polk's heavy new-pool and new-construction volume — plan on a few weeks at the building department. We submit for you and resolve reviewer comments free until approval.
Typically around 139 mph (Vult) per ASCE 7-22, confirmed per site during design. A tall clear-span cage catches heavy uplift, so the wind speed, exposure category and component-and-cladding pressures are calculated for your exact address.
It can — but only when permitted, inspected and detailed for it. Florida's residential pool barrier rules set requirements for the screen walls, gaps and a self-closing, self-latching access door. An unpermitted cage does not legally qualify. We can prepare the drawings so the enclosure is documented as the barrier.
That corridor is adding new pools fast, and most get a cage soon after. You'll usually need both HOA architectural approval and the county permit — two separate processes. Our sealed engineering covers the county requirement and generally satisfies the HOA's documentation too.
Yes. Many Polk pool cages sit on vacation and investment homes near Four Corners whose owners never set foot in Florida during the process. Everything is handled remotely from your survey and photos.
