My experience using RMB for a dock reface was excellent, there work was superb, professional and was priced very competitively. The workers were very friendly and courteous and always made sure the site was reasonably neat at the end of each work day and then thoroughly cleaned at the finish of the job. Rob answered all my questions was very knowledgeable and extremely friendly.
