"Paul was great, can not beat his customer service, on time, when he said he was going to be there. A true professional, found the leak and stoped it. I will always use classic Plumber for any and all jobs in the future. "

"Nathan (Alfco) was very professional, knowledgeable, courteous and friendly. We had a shower enclosure replaced with a updated sliding door enclosure. Nathan walked us thru the entire process and gave us a VERY reasonable price. We will use Alfco with all our plumbing and relate needs. Sincerely, Ben and Kris"

"I had a tankless water heater installed but needed the gas line to be dug from the other side of the house for it to be connected. The job was complicated but Luke and his crew from Mr. Rooter did a great job! I would totally hire them again for any plumbing needs. "

"Finding Wayne during a bad snowstorm was like finding gold. Temps outside were single digits. My heat was nonexistent and I thought no one would come out to help me. Wayne not only came out but he quickly fixed the problem. I had no other source of heat and could not get out to pick up the heaters I ordered from Walmart plus I was very sick that day. Wayne actually went to Walmart for me (his idea) and got me the heaters I needed. That was above and beyond! I cannot say enough good things about this man. He is fair, honest and a genuinely kind person. No upselling. Wayne is a true professional and a jewel of a human. Five stars without hesitation. Highly recommend."

"Rance Came to our home on time and gave a careful evaluation of a job I needed done. Rescheduled it for approximately a week and a half out. That day he again was on time. He removed my old hot water heater and placed the new one in its new location and adapted the Plumbing. He was very clean and wore protective covers on his shoes. He was very courteous and informed. And when I needed to adjust the list of services I had agreed to, he gave me no quarrel. He removed the item that I no longer need. Excellent service from excellent people!"

"Professional. Experienced. Fairly priced. Communicated well. Showed up on time. Installed a Pioneer mini split for our basement. Great experience. Thank you."

"The Plumbing Authority got back to me right away once I connected with them on Angi. We agreed on a date and time for them to come to my house and they were there exactly when they said they would be. Mikhail was very polite and professional and didn't try and "upsell" me anything. He kept the area that he was working in clean and when he left you wouldn't have known he was ever there except for the leak problem had been fixed. He completed the work very timely. I like The Plumbing Authority very much and would highly recommend them. "

"Save your money!!! This company, Proflow and another company, Best plumber were both hired to service my water heater.. Both companies charged me to clean tank and replace a burnt out bottom element.. 1st company, Best Plumber in July 2025.. 2nd time I went with proflow in Jan. 2026 (mind you this is a mere 3 months ago).. they both charged for element replacement and a cleaned tank to best of ability.. Proflo charged me $259.00 for this service.. it?s now April and I needed a plumber yet again (like I said, only 3 MONTHS after proflo services) I have included pictures of the 2 piles of calcium sediment from tank that the most recent gentleman did while servicing.. his exact words, ?this hasn?t been cleaned; this is at least 5 years worth the sediment?.. guess what?! My tank is only 6 years old!! Proflow charged me for a job that was not completed.. even better they charged the ungodly amount of $259 while this most recent company only charged me $130(cleaning and 2 elements)."

"Came out within 24 hours and completed the repair first time."

"They did a great job, and they're going to do our water heater inside as well! We were very pleased!"
