"Gerry responded to a leak in my front yard watering system and was able to quickly come over so that I could keep a scheduled trip out of town. He did a great job repairing my watering system leak and also fixed my inoperable shut off valve. I also asked him to look at my hot water heater to determine why it wasn't heating effectively, and he easily spotted and fixed the problem.
He was a pleasure to work with! I will definitely use him again and highly recommend him.

"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."

"They showed up on time, made a minimal mess, did a quality job replacing 2 complete heat pumps systems and were very good about explaining everything along the way. They even filled out the rebates and sent them in."

"Glenn was an incredibly knowledgeable educator, above and beyond the other companies we spoke with. He also really didn’t want us getting anything but the best and wholistic options for our family’s situation and home. The warranty was great too! We had a water heater removed and replaced, reverse osmosis filtration installed, and a whole home filter and conditioner fitted. The water tastes great from everywhere in our home! The plumber on site was friendly and quick. 4 months later everything is working perfectly. Glenn was fast and constant with communication the whole time. If you need any work done related to water- highly suggest giving Aquaco and Glenn a call."

"Steve arrived when estimated and determined what needed to be done, left for a while and retuned with a very good water heater and drip pan and began the change out. He cleaned the area and hauled the old water heater away. The installation looked professional."

"Hired to Install and maintain Hot Water Heater. Provided prompt information and came ahead of scheduled and completed the Installation, and while there, performed a maintenance of my inside plumbing to see if there were any problems! Definitely would recommend this Company, their pricing for service is very comparative to other Plumbing type companies."
