Great job,had my Softner up and running in less than 45 min.

Christian and Kelly are pros. They listened to our needs and offered two great suggestions.

Jordan did a very professional job and he did it in a timely manner too. I would recommend him for any of your plumbing needs!

Nickolas from CGC Home Services installed our new Kinetico Water Softener and RO Water Filter. He explained everything he was going to do before starting, confirmed placement options and after installation gave us a very good overview of what ongoing maintenance is required and approximately how often. Everything was neatly completed and cleaned up when finished. We would highly recommend Nickolas for his work.

Joe was fabulous… did a super job on the tankless flush and had a terrific personality. CGC ROCkS!!!!!

Great service. Would highly recommend

Very nice courteous young man! Even brought my garbage can up from the curb. Very thorough and quick!

Kade was polite and he explained to me what was the issue with my softener.

Aidon did a great job today on our install. Very polite, professional and knowledgeable.

Today was salt delivery day, and as always it was a pleasure to see Jason Williams. He’s just such a good guy, and my dog is over the moon when he sees him. I think Jason has that effect on lots of dogs. And, I really appreciate the salt delivery service, as those bags are so heavy and buying them at a store is an ordeal. Thanks CGC/Kinetico and especially Jason for the great service.

Professional and knowledgeable

Always on time and professional service. Honest too.

Gavin was very professional and ensured he answered all our questions before he left.

He was very proficient and helpful when answering my questions

Renee was helpful polite and knowledgeable. An all around great guy!

Dan called about 10 minutes before the scheduled arrival window to let me know he would be at the house shortly. When he arrived, he introduced himself, listened to the issue we were having with the water softener, and then fixed the problem.

We had a water treatment system installed about 2.5 years ago. We’ve been happy with it until today when I learned that every 1-2 years, we will have to spend about $1k on carbon filters. This came as an absolute shock to us because when we bought the system, we weren’t told about the added costs. We only had the filter under our sink replaced today for $350. Soon we’ll have to spend $600+ to replace the carbon filter in our garage. I guess I should have asked but knowing nothing about water treatment, how would I know? If you’re having a water treatment system installed, ask about future costs.

They were polite, answered all my questions and did a good job replacing a broken water pipe shut off valve.

Will was very knowledgeable and courteous
