We live in Celina, TX and we're planning to build a pool. We have never owned a pool and know nothing about them, so I'm not even certain what questions to ask or how to distinguish a good builder/well built pool from a poor one. I have contacted a few local companies and am currently in talks, but the only criteria I have for selection at this point is years in business and internet ratings. We live on 1 acre, have an open/flat yard, but have black clay soil. We want a free-form pool - with water feature, but no spa. Any input is appreciated.
