If you own a pool in Florida, cracks are something you will likely deal with at some point. The Florida climate is tough on pools. The heat, the shifting soil, and constant use all take a toll over time. A cracked pool is not just an eyesore. It can also lead to water loss, structural damage, and bigger repair bills if you ignore it.
This guide will help you understand why cracks happen, how to spot them early, and what the repair process actually looks like.
Florida has a unique set of conditions that put extra stress on pools. The ground here is mostly sandy soil. It shifts and settles, especially after heavy rain or drought. When the ground moves, the pool shell moves with it. That movement causes cracks.The heat also plays a role. Florida summers are intense. Pool surfaces expand and contract with temperature changes. Over many years, this repeated expansion and contraction weakens the structure.
Tree roots are another common cause. Florida has a lot of mature trees. Roots grow toward water sources and can push against pool walls from below. Even poor original construction can show up years later as cracks. If the concrete mix was wrong, or if the steel reinforcement was placed incorrectly, cracks will eventually appear.
Not all cracks are the same. Knowing the type helps you understand how serious the problem is.
A cracked pool will often lose water faster than normal. But it is hard to know if water loss is from evaporation or a crack. Here is a simple test you can do at home. Fill a bucket with pool water. Place it on the first or second step in the pool. Mark the water level inside the bucket and the pool water level on the outside of the bucket. Leave it for 24 hours. Check the levels again.
If the pool water has dropped more than the water in the bucket, there is likely a leak. If both dropped about the same, it is probably just evaporation. Water loss of more than half an inch per day is a sign something is wrong.
You should inspect your pool regularly. Once or twice a year is a good habit in Florida. Here is what to look for.
Repair depends on what kind of crack you have. Here is how the process generally works.
Small surface cracks can sometimes be patched with DIY pool repair kits from a pool supply store. These kits work fine for minor cosmetic issues. They are not a long-term fix for serious cracks. Structural repairs should not be a DIY job. Getting it wrong can make the problem worse. An improperly repaired crack can still leak. It can also hide a bigger issue that ends up costing more to fix later.
As for how long repairs last, a proper structural repair can hold up for many years. Surface repairs tend to last five to ten years, depending on pool chemistry and how well you maintain the water. Keeping your water balanced is one of the best things you can do to protect your pool surface long term.
Call a pool repair professional if:
In Florida, pool repair contractors should be licensed. Always ask for their license number and check it with the Florida Department of Business and Professional Regulation.
Cracks in a Florida pool are not unusual. The climate and soil conditions here just make it part of owning a pool. The key is catching problems early before they turn into something bigger. Take the time to check your pool a couple of times a year. Know what normal looks like so you can spot when something changes. And when in doubt, get a professional opinion. A small crack repaired today is much cheaper than a structural failure repaired next year.
