So this is going to be my third attempt at building a pond and getting it to hold water. I am in central Arkansas at the foothills of the ozark mountains. I have had two previous by two different pond builders and neither has came back to make good on their work. Both times no contract in writing so my question is to make sure I get reputable builder this time which I will going with a referral from Mr.Lusk is it a common practice for pond contractors to not provide a contract in writing with a guarantee or should a reputable contractor be willing to provide one?
