"I have had the best experience with Gibraltar, and I cannot say enough about the people who work there and the product itself; we love our pool!! Itâ s given us a lot of joy this summer with friends and family. But foremost for my review is the people who I have interacted with since we purchased the pool in the summer of 2020- they are awesome. Really the best. I have not seen customer service like this at another company in a long time. We put in our new pool last November for a deeply meaningful reason for our family and I ended up talking with the CEO and shared with him the reason. He was so awesome and wrote me such a sincere, kind, and genuine note. From the CEO to the college kid on the floor and everyone in between- I have been so impressed with their patience, knowledge, friendliness, and professionalism. Iâ m so appreciative to Peter, Ellen, Grace, Ana, Jason, Keith, Jim, Ryan, Wayne and Jim. They have all been so incredibly awesome to deal with, and I feel like I am working more with a family than a huge company. Itâ s amazing they employee so many people who are each individually so helpful. You can tell the owners really care about how their store is represented and that they care about the quality of their work. We (like several other families) decided to build our pool during quarantine in 2020. There were delays that no one could have foreseen because the supplies were impossible to get for months- but that was no oneâ s fault, no one could have guessed we would be in a pandemic, and that the demand for pools would go up so much. So, even though there were delays, we understood, and Gibraltar did everything the could to get our pool built as quickly as possible and to make sure it was open for the summer season of 2021- and it was. I was sad to see reviews that said they took too long- I honestly just donâ t think it was fair. Who could have foreseen the impacts of a pandemic? So, for us, the delays were what they were, and we appreciated that they did all they could, with what they had to work with, and kept up updated along the way. I would highly recommend Gibraltar to anyone who wanted to put in an awesome above ground pool and have superior customer service."

Install Above Ground Pools FAQs, answered by experts

Customization options may include different pool shapes, sizes, decks, and additional accessories like ladders or pool lights.

Concrete pools have the longest life span. As long as you properly maintain your concrete pool, you can expect it to last 50 to 100 years. That said, you will need to resurface your concrete pool as it ages. Fiberglass is durable, but fiberglass pools generally only last around 25 to 30 years. That said, some high-end fiberglass pools can last more than 50 years if they’re well-maintained.

Fiberglass pools last the longest because they need the least amount of maintenance and do not have liners that can affect a pool's integrity. Concrete pools last the longest, next to fiberglass.

A well-built and well-maintained concrete pool should last anywhere from 50 to 75 years. Concrete is prone to cracking, so winterization and regular pool repairs are particularly important. Water can seep into existing cracks, freeze, and make them worse. Most homeowners should resurface their concrete every few years to maintain their pool’s lifespan. 

It is possible to restore a filled-in pool. If you want to dig up and repair a filled-in pool in your backyard, the process will cost about the same as the cost of installing a new in-ground pool. You might do this if the filled-in pool is causing sinking, swelling, or drainage issues in your yard. A new pool may resolve these problems and increase your property value.
