"My husband and I were referred to CGC Water by close friends. Everything from the first appointment with the sales man to having the project complete felt very intentional and customer focused. They took water samples, listened to what we wanted, answered all of our questions (we had plenty) and set us up with everything we needed. I was really happy that they got us on the schedule quickly, we did not have to wait 4+ weeks that other projects have taken. The install was very thorough and even though nobody will see the equipment the install spot was left clean and the piping all looks nicely hung. That may not matter to everyone but I noticed. Before leaving, the technician made sure all equipment was working and retested the water to make sure it meets our expectations. Now we have a Kinetico whole house water softener, and a Kinetico RO drinking water system. I am so glad we went with the Kinetico system. I can tell a difference in everything! I dont get spots on the dishes anymore, my towels dont smell funky after washing them and having good water has even helped with dry skin. I love the drinking water too! I really can tell a difference from other drinking water and I always fill my water bottle up at home before leaving the house because other water just does not compare. I really appreciate the follow up as well, we opted for the scheduled salt deliveries and filter changes so we dont have to worry about it as much. I highly recommend CGC and the Kinetico water equipment."

"Having owned four different houses the past 16 years, this was hands down the best experience with a plumber... ever. We hired WyattWorks to install a laundry sink (the stainless over cabinet kind) which required drilling through the floor to tie-in with supply and drain pipes in our basement. Jeremy performed the work flawlessly and was a true pro: measure and recheck, plan and dry fit, and clean up the work area during and after. The whole process from start to finish was painless!"

"The individual who came to my house to give me an estimate did an outstanding job explaining everything. Due to the extensive modification that would have been required to install a tankless water heater I replaced the existing water heater in kind. I would not hesitate to hire them for future work."

"They came and gave me a quote of 4500, I needed the job done so I hired them They sent another company to suck the tank out and they discovered that my tolites was running water they had some suggestions well I repair them and that fixed my problem then the guys from superior came and run the pressure washer and the job wound up costing me 5144 and in advance I told them I was on disability and fixed income, I highly recommend looking around before taking with these guys I know I feel like I was taken advantage of, they will never do any business for me again, another company found the problem and told me how to fix it, I fixed it, and superior made the money for it to me this is a big ripoff"

Customers say: Quality work

"Doug and his crew from Checkered Flag Plumbing came into my condo/townhouse with a total of 4 guys to help strip out the old water heater and install a brand new Rheem for me within a days notice of contact. Doug and his crew were super professional and kept in consistent contact with me throughout the day and even follow-up me later on additional information regarding an extended warranty on the water heater. Because of this, I would highly rate my experience a 5.0 as I was able to receive hot water within 45mins to an 1hr after installation. Would highly recommend this team."

"Our a/c broke and I put a request for quotes on Angies List. Tara from Ace called me within 5 minutes. She sent out Daniel and he was so thorough. Another company came and said it was a leak. Daniel didn’t find any leaks and he thoroughly looked. He had the air up and running in 3 hours. I highly recommend this company."
