Hi! Dreaming about getting an inground pool. Interested in a fiberglass pool due to smooth surface, decreased maintenance, and wanting to use a saltwater system. Does anyone have a recommendation for a pool builder near Madison, WI that does fiberglass? It appears there are only 2 companies nearby. One that deals strictly with San Juan, and the other that installs Imagine Pools. Also, which fiberglass pool manufacturer is better? I really love the look of some of the Leisure Pools, but there are no installers in the area. Any troubles with fiberglass pools cracking due to freezing conditions in winter in our area? Any advice is greatly appreciated.
