I'm starting to plan a spring 2017 build in Northwest, Ohio. First let me say I am can't believe the price differences between the sunbelt and the rustbelt. Pools just seem so much cheaper in the south and west. I am leaning towards being the general contractor and subcontracting the work out. It seems like concrete pools are rare in the north is this because of the winters and cracking issues? I am leaning towards a steel wall vinyl lined pool. Any recommendations on where to purchase a kit from? Any suggestions on subcontractors in northwest ohio?
