Mine was one of those tricky jobs because of sewer lines, sewer cap, existing certified wall, and a lack space between house and a steep drop-off . I had more than a handful of tradesmen come to offer a quote. More than half didn't even want the job. John not only had the necessary equipment and expertise to complete the job, he exceeded my expectations of the finished look and maximised the usable space around my house. Great advice. Great service. Great price. Get a quote from John before you make your final decision.
