Professional Tankless Water Heater Installation Services

Very friendly and efficient! Answered all my questions! 👍🏻👍🏻🇺🇸

Kade came out because our water pressure was low and water was a little hard. He fixed everything up and since I had had service recently, there was no charge. CGC is so great to work with. They are so nice. I highly recommend.

He kept me apprised of his ETA, was friendly and worked quickly & efficiently.

⭐ 1/5 — If zero stars were an option, I would give zero. I am writing this review after receiving no response or follow-up from CGC Water Treatment regarding several serious, unresolved issues. System failure: Our water treatment system experienced a major failure within the first year. Misleading product information: At installation, I specifically asked whether I could continue using standard filters and was told by the installer that I could. I later discovered that the system requires expensive proprietary filters. These filters were also presented as reusable/washable, but I found them extremely difficult and time-consuming to clean. Billing issue: A $50 coupon I presented when purchasing filters was never applied to my balance. Despite multiple emails detailing these issues, CGC has provided absolutely no support, response, or attempt to resolve the situation. Due to their complete lack of communication, I am now moving forward with formal complaints to the Better Business Bureau and the Michigan Attorney General's Office. I strongly advise others to look elsewhere for their water treatment needs.

Came out right away and did a good job.

Jason is outstanding.

We called this company to replace the expansion tank on our well-pump system. The technician insisted they would install only a fiberglass tank. Eventually, they agreed to install a steel tank if we purchased it ourselves—which we did, for about half the price. The tank is located in a laundry room, not a basement or wet environment. The installation was completed on Friday and cost just shy of $1,400. I was out of town and unable to handle the work myself, so we reluctantly accepted the price. By Saturday, just 24 hours after the Friday close of business, one of the newly connected pipes burst, spraying pressurized water inside the house. Thankfully, we shut off the water within minutes. The company advertises emergency service on its website, so I called immediately. An AI voice collected my information and promised someone would be in touch. Four calls and almost 14 hours later, we never heard from an actual person but we were able to book an appointment on the website for Monday. At first, the earliest we could book was Wednesday, but we managed to negotiate our “emergency” down to only two days without water. Apparently, their emergency service consists of an AI answering the phone and offering emotional support while your house floods. We ultimately found another company that came out and repaired the burst pipe the same day. That was fortunate, because waiting until Monday, or Wednesday, without running water was not especially appealing. Oddly enough, the technician showed a highly corroded piece of steel pipe thread into a brittle and cracked pvc connection at the exact connection point to the tank. I guess that inspecting the connecting pipe was a little much. From the insistence on the more expensive tank, to the nearly $1,400 installation, to the pipe failing the next day, to the nonexistent weekend emergency response, this experience was unacceptable from start to finish. I would not recommend this company to anyone. One star, only because Google has not yet introduced negative numbers. Please, for the love of all things Holy, do not use this company. They basically took a donation of over a $1000 and made our plumbing issue worse.

Very professional and informative.

Ronnie was courteous, knowledgeable to recheck repairs on Thursday last wk

Ronnie is very knowledgeable and took the time to show me what was wrong and discussed all available options. Thanks!

Great service, had a enjoyable time!

CGC did an amazing job with our water softener installation. Joseph was fast friendly and left our home clean! We are super happy!

Justin is the consummate professional. Thorough, knowledgeable, and congenial. I trust him with the work that we need done. I've requested him by name in the past and will do so in the future. On top of everything else, he's a Veteran of the United States Marine Corps. Doesn't get any better than that! Thank you Justin!

Justin and Jordan were great, and we are anxiously awaiting them to complete the work we discussed.
