We have chosen to work exclusively with the Viking product because our reputation is important to us. After researching many pool options, we felt the Viking fiberglass product would best meet the needs of our clients for a number of reasons. First, all of the beautiful shell choices have a lifetime warranty against fading, cracking or peeling. Next, unlike concrete pools the smooth fiberglass finish decreases the ability of algae and bacteria to stick to the surface. As a result, far less chemicals are needed to maintain a crystal clear swimming environment. Also, heat retention is superior and water evaporation is reduced which makes for a highly energy efficient pool.
