"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"I have had worked done by Pepe from Reddi Services several times and he has always been great. He has fixed bathroom fixtures which were incorrectly installed by other plumbers, replaced a sink, water heater and water softener with the expertise and professionalism you'd expect from your plumber."

"High quality work, professional, trust worthy, took the time to explain everything to me; also educated me on my current hot water heater, pricing for a waterless hot water heater, & the issues related to my current gas hot water heater because of my water softener. I would highly recommend Jonathan Maynard from Tucker Hill Plumbing."

"We were looking to have a tankless water heater installed and went through Angie's List to find a reputable company. We had many companies contact us, but we felt that Glenn Giolito with Aquaco was the most honest and sincere person to deal with. He demonstrated excellent product knowledge and was very helpful. When we found out that Aquaco also had soft water systems that we had been thinking about having installed, Glenn again came through and set us up with a great soft water system and a reverse osmosis system in the kitchen. We're very happy with the work performed by his crew and highly recommend doing business with Glenn at Aquaco. We thank you very much, Glenn."
