I am currently in the pool builder selection process. I have 2 separate companies providing me bids and pool designs. The major difference between the two is that one says i need a retaining wall on the back side of the pool for my 18" slope (slopes downward from the back fence line towards the house) and the other says it isn't necessary. Can anyone provide insight or should I try to get a 3rd opinion? I am a first time pool owner so any help is appreciated.
Pool located in McKinney, TX
