After being quoted something ridiculous by another company to replace a hot water system I spoke to Mark from Rock Solid Plumbing and was given a quote that was much more reasonable. Mark returned my call immediately, he gave me a time that he would come out and he turned up on the dot. I was very happy with his work, he was polite, he knew his stuff and cleaned up after himself. Very professional. Would recommend him any day. Thanks Mark for your prompt service and getting hot water back into our home.
