"It went very well! Doug was on time, friendly and professional. He found a problem which we will have repaired soon."

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Came early and removed and installed a new water heater within 90 minutes"

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"The firm responded immediately to my inquiry and arrived at the scheduled appointment date, assessed the necessary repair, went to the closest plumbing supply house and obtained the necessary materials and returned promptly that day to make the corrections. The crew was courteous and professional."

"They were readily available for an emergency we had regarding pipes and water leak. Very professional, reassuring and fixed the problem in one day! Would definitely rehire!"

"Included in the price of the 50 gallon water heater I needed was the plumbers picking up the new water heater, transporting it to my home, navigating the steps down to the basement, and taking away the old water heater. All for the price on the receipt for the new water heater. What Mr. Simpson charges for is the installation of the new water heater and the peace of mind that comes with having a master plumber do a masterful job. Articulate, polite, and efficient, he made me aware of everything he was doing every step of the way. He is obviously a person who takes pride in his work. Mr. Simpson's work comes with a guarantee to amend any problem that arises. A guarantee I have not needed to avail myself of, but appreciate nonetheless. I am thoroughly satisfied with the job he did, and recommend him as an honest tradesman."

"Heater was making a knocking sound and of course it was the holiday season. Braido came out right away and found a fan part needed replacement. The parts vendor was closed but they came out the next available day and had everything running smooth."
