Decades ago, concrete pools were the be-all and end-all in the pool industry but since fibreglass pools hit the market, they have become increasingly popular amongst pool buyers and are the new go-to option. This due to their quick installation, durability and low maintenance. Fibreglass is smooth and nonporous which prevents algae from attaching to it and manifesting. Concrete, on the other hand, is highly porous and the tiny nooks and crannies in the finish make the perfect environment for algae to nestle in and grow. This means more money needs to be spent on cleaning and more time too. Not only that, concrete pools can take anywhere from 3 to 6 months to install and because they are built from scratch, they are usually far more expensive. They need to be resurfaced every 10 to 15 years and this averages around $10,000. Fibreglass never needs to be replaced or resurfaced over its lifetime. Once it's in the ground, that's it.
