"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"

"They gave me several choices for the water heater where other companies only carried one or at least did not offer others. I also appreciated the fact that they gave me a quote over the phone. They were knowledgeable about their craft and expedited the installation once I had made a decision. I also liked that I could buy the toilet myself and they quoted just the installation so I did not have to pay the mark up for the hardscape. I am changing all of my plumbing needs to this company."

"After purchasing the Big Deal, I was contacted within 1 day. The appointment for the inspection was scheduled within 2 business days, the installation was done, within the week.  Not only did these Professionals install the furnace, condenser and air conditioner. They completely redid the venting of the furnace and hot water heater, moved the electrical and water lines in a more efficient route, and built a pad for the air conditioner complete with pea gravel  and substantial pad.  In my 35 plus years of ownership I have never been so happy with a contractor. Very responsive to my questions about maintenance of the units.

"I am very pleased with the great customer service I received from Mike D. at Lifeline Plumbing for the replacement of my 16 year old water heater. Mike had a great personable, upbeat personality, a great attitude, and with his 18 years of experience, he was confident as well. When going over my options, he was patient, not pushy. He made sure I was confident with my decision. I felt comfortable with him and I also trusted him. He was professional, fast, and efficient. I would highly recommend Mike for your needs as well. I know you will be very happy with his service."
