"They care! They stopped by to address a hot water heater on the blink but the weather was brutally cold and Mikey saw me working on the boiler… After addressing a plan to convert to tankless, he helped me make the decision to switch to a tankless combi solution. Very happy how the team took the time to complete the job timely. I will use them for other projects for sure"

"Called Home Depot at 6:03pm on Saturday 2/26/22. At 6:30pm Arctic Air Conditioning contacted me, had me take photos of my broken hot water heater. 15 minutes later, Katie from Arctic called me back with a more than fair price and worked her magic to get me an install for Sunday 2/27/22 at 2pm. Alex from Arctic arrived Sunday around 2pm and started the project. Elijah from Arctic arrived 45 minutes later and by 6pm ( 24 hours after my initial call) we had a new hot water heater up and running. Great experience, Alex and Elijah were professional, knowledgeable and courteous."

"Service Tech Ed DeMore, who had originally installed our tankless water heater, responded and realised the unit had to be reset and recalibrated after an error message caused the unit to stop and not restart during the snowstorm of last Monday. He had us up and running in just a short amount of time. Eddie is an excellent and knowledgable employee with a great attitude. He is very pleasant and we hope A. J. Perry realises what a great asset they have in Ed."

"The plumber answered my initial call and I was able to describe the problem we were having with the guest room shower fixture that only produced very hot water. I sent him a photo of the fixture. He came the next morning and replaced the cartridge, unclogged the drain in the tub, and fixed the stopper that was not closing properly. All of his services were priced reasonably!"

"We purchased a house and adding a whole house water filter was on our list. Our local Orbit dealer performed a free water test and confirmed a that a lot of the junk we had read was in our city water was in fact there. Our previous house also had hard water and we saw firsthand what it did to our pipes and hot water tank. Plus we were tired of a filtered water pitcher taking up space in our refrigerator. Our sales person went over all of the features of the Puronics 7000 system and outlined the maintenance which simple and easy to understand. Installation took place about two weeks later and the guys were done in a day. About a year out and we're still very happy with the improved water quality and the system itself works great."

"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."

"I wish I could hire someone of Roger's calibre, brilliance and ethical principals on all projects I need to accomplish around our home. It is a pleasure to have Roger for a service call or job as he willingly shares his wealth of knowledge to assist you in understanding all aspects of your home systems. He takes his time and explains each and every detail in an easy to understand way . Not only is he straightforward, honest, highly efficient and extremely knowledgeable but if you need to call him he will guide you through all issues and concerns and explain the steps you need to go through to do such things as change your filter if you wish to do this yourself. I would definitely highly recommend Purely Water with Roger Garrett. I believe he will work with you to achieve whatever you are trying to accomplish."
