The pool contractor I had got my fiberglass pool from Water World. I paid him, and he did the installation. I got the excavator and the electrician - This is the 7th year for my pool and it still looks new. They do honor the warranty, the only thing I had done to mine is to have the rim of the pool re-gelcoated due to little cracks that are common. They don't hurt the pool, just look ugly. I have been very happy with the pool.
