Why Pool Cages Sag and How Retrofitting Fixes It

POSTED March 25, 2026 BY Absolute Aluminum

Why Your Pool Cage Looks Like It’s Sagging and What Can You Do To Fix It?

• Pool cages can start to sag from weather, age-related deterioration, or structural mistakes during installation.
• Retrofitting can make your pool cage work like new at a lower cost than full replacement. 
• Absolute Aluminum specializes in pool cage repairs and retrofitting around the Bradenton, Florida, area.

Pool cages protect your pool from unauthorized entry, pests, and debris, and well-designed cages can look great while doing it. But if you notice drooping ceilings or leaning walls, it is important to determine whether the structure is actually failing or just appears that way. Depending on the extent of the damage, it might be time for a full-scale replacement, or you might be able to restore your pool cage to its former light and lifted look with professional retrofitting from Absolute Aluminum.

Why Pool Cages Sag

Sagging pool cages are a clear sign of deterioration or improper installation. If the cage is experiencing “sagging” due to a minor beam issue or screens being improperly installed and giving the illusion of sagging, it’s an easy fix with a retro or rescreen. But if your pool cage is on the older side, here are some different explanations behind why parts (or all) of your pool cage might be starting to sag:

• Weather and sunlight damage. The bright Florida sun, strong storm winds, and salty air could combine to make the screens brittle and force them to bend and break over time. Storm debris can also blow against the cage.
• Material deterioration. The rubber splines that hold the screens in place won’t last forever. Weather conditions and years of holding screens under tension will wear out some splines. The screens themselves can also stretch out after several years. 
• Structural damage. The frame itself can deform from physical impact, weaken after years of exposure to the elements, or simply shift in the mounts over time, making the screens sag or fall out of alignment. 

One or all of these conditions can make your pool cage start to sag. If the cage is actually sagging due to age, deterioration, or significant damage, it would need an assessment and, depending on the extent, may need to be replaced. Once you see the first sign of sagging, call in an expert for a professional evaluation.

Structural Stress Points

For serious sagging, the structural frame may be the main culprit. You can visually assess these structural stress points for damage from wind, storms, or age-related deterioration. A professional will evaluate these spots to see if you are a good candidate for a retrofit or if a replacement is necessary to ensure safety: 

• The load-bearing anchors that connect the cage to the concrete deck, as foundation stress and impact can lead to sagging
• Fasteners that can loosen, go missing, or corrode over time
• Stressed corner joints
• Rafters that are sagging due to loose connectors or excess weight from pooling water and debris
• Loose or damaged hurricane cables

Dirty screens can also put a high load on the structure. Just like a clogged AC filter, buildup can stop air from passing through the screens and create heavy wind resistance.

How Retrofitting Straightens Frames

Professional pool cage technicians can assist with any and all of these types of damage. If the frames are misaligned, bent, or broken, the team at Absolute Aluminum can identify the problem through an in-depth evaluation, recommend repairs or replacement parts for specific sections, and suggest updates to make the pool cage stronger and more resilient in the future. Our team can also replace brittle screens and splines, giving the entire cage new life.
