I have done business with Seepage Control and they have always treated me very well and fair - my experience has been first class all of the way. I also believe they are an advertiser and supporter of Pond Boss and I appreciate that - I don't think Bob Lusk would take them as an advertiser if their product and company was not reputable and proven. I don't remember whether I paid a deposit or not, but that would just seem to be a prudent business practice, particularly in this economy.
