We interviewed a few pool companies and ultimately decided on thunderbird because of their quality for the same prices (and some cheaper) than other companies. Everything they use is higher quality and they guarantee all their work.
Like with any long construction project, timelines and waiting can be frustrating... but they really did answer our questions and calls.
Every trade that came by was top-notch professionals and meticulous about their measurements and work. In the end, there was a slight problem with one aspect, but thunderbird sent people out right away to check and was adamant about getting it fixed for us at our convenience.
Overall we are in love with the pool design and the quality. We will be recommending them to friends and family.
