Steven Wilson was the sub contractor who poured an exposed aggregate concrete pad around a portion of our pool and spa. THE EXPOSED AGGREGATE CONCRETE DECK = A The major challenge was making the new deck match the exposed aggregate deck that had been in place for 30 years. Steven did a more than excellent job at matching the exposed aggregate stone color, texture and overall look. He did some additional work in acid washing and sealing the deck to make sure it had the same appearance of the existing pool deck, which is very difficult to achieve having seen other contractor's work. There was one particular area that needed extra effort to make sure it matched the existing form/shape of the pool. I had to question this area several times and Steven worked on it until it looked good and matched my expectations. I appreciated his extra effort. We are very happy with the result of his work. THE PROCESS = B- Steven was always willing to do whatever we asked him to do. All we needed to do was point out any problems and he would fix them. This is the one place that was not as customer friendly. I didn't like having to keep pointing out things that were wrong -- Steven is truly the expert and I wanted him to tell me what his plan was to address any issues. In one case, we thought he was finished with the work and he had advised us that acid washing the deck would help expose the aggregate more. So we did that. Then two days later, he shows up with his crew to acid wash the deck (a stonger solution than we had used) and it did turn out even better. We were very appreciative of the additional work that he did to make the deck look better, but if we had known he was going to do that, we could have saved our initial effort. Steven emphasized that he wanted to make us happy, He would ask us what we were unhappy with or what things needed to be cleaned up. Sometimes his response was that he had already planned to take care of that issue, but he didn't communicate that until we asked for it. Granted, the general contractor should have been the one overseeing the whole process so we did not have to be the quality control inspector, but to a certain extent I expected Steven to be his own quality inspector and tell me when the job was done. Again, we are very happy with the results of Steven Wilson's concrete work (which is most important) but felt the process could have gone smoother.
