Testimonials

“They were extremely diligent and pleasant. They also were able to complete all the work in the projected amount of time. I also want to add that Dan was very quick to respond to all emails and inquiries my mom had. Overall, a really great experience for such a big job and we would highly recommend them to anyone.”

“I have used Klaus and Sons for plumbing (I live in a 105 year old house), laying a water line and, most recently, installing a new gas line. I have always found their work to the best available in my area. On a couple of instances I chose other local plumbing services for simple repairs, thinking I could save a few dollars, but most of the time I regretted the decision.”

“We had recently had a plumbing issue at our house. Klaus and Sons responded quickly, used cool technology to find the problem, and fixed it.”

“Dan came out to give an estimate on a new HVAC system for us. He was courteous and very knowledgeable. He did not seem to be in a rush to leave either (which was great). He provided an estimate through email in a timely matter and answered all of questions I had.”
