Michael gave me an estimate on a water filtration unit and was very knowledgeable and helpful. Thank you very much!!

Brennen was very nice, knowledgeable and personable. He is a great representative of your company and services.

Renee was helpful and friendly. He explained well what was needed and even showed me. I don't like spending just to maintain the status quo, but his recommendations will improve my home's water handling and reduce my energy cost, thus put me in a better place!

Tested/fixed my water Kinetico softener.

We had a rupture in our well system at approx 3pm and in calling the team, they were out the same day to diagnose the problem, and the following day to do the repair/replacement. The technician (Noah) even stayed past 5pm and brought his shop vac out to help me clean up the flood in our basement. He didn't have to do that, but was more than willing to help someone in need. Would absolutely recommend him and the team!!!

Jordan was very knowledgeable, very thorough, and very nine. He was not in a rush and gave me all the time I needed. Thanks for all the help.

I have nothing but good things to say about CGC. Professional, courteous, efficient, and they know water! Their staff members are punctual and communicate well. Jonathon diagnosed our water issue and came up with a solution which was completed within 24 hours. CGC is where to go for all of your water needs!

Ronnie was great. Didn't take him long to solve the problem. Good service and pricing. Thanks!

Jonathan came by today to add salt and cycle our softener. He also changed out the sediment filter and charcoal filters. He called about 30 minutes before arrival to let me know he was on the way. Everything went well.Thanks!

I want to thank William for the help he had offered! He went the extra mile in making sure the system was working properly and he took his time doing so instead of rushing around like most people do.

Overall, greatly appreciated and would recommend the service to others. 5
