Swimming Pool Co - League City area (wanted)

My family and I are interested in adding a swimming pool to our backyard. I know I can complete a quick google search for a company in the area (already did that), but I also wanted to hear the good, bad and ugly of owning a pool.

After weighing through all the potential issues or problems, I plan on getting a few local companies to give me estimates on an average setup. If you have had success with any pool company in the League City area, please let me know.

Greatly appreciate the assistance.
