"I did have Davis & Son repair my Heating system and they did a very good job. When I called to have them install a gas line (about 10 feet), they were going to get back to me with a quote and timeline. That was a month ago - nothing. I called and had another firm complete the work in 3 hours. Disappointed that they never called back."

"Isaac did a great job plumbing my house and my shop. Isaac did everything from rough in to finish product. He showed up in a timely manner and took pride in his work. Not only did the plumbing look nice when he was done it all functioned like it was supposed to. Highly recommend Issac for any of your plumbing needs."

"Pulled toilet to access drain. Reset toilet after examining drain lines from basement to septic tank. Explained findings in detail, offered opinion and options for correcting situation including continued observation. I would not hesitate for a moment to use Mr Martin again or to recommend him to family or friends. Thanks for a great job and especially on a Sunday!
