"Mike & crew were beyond my expectations! Needing septic repair and trying to find a competent and reasonably priced professional is harder than it should be, until I found MKB Plumbing and Septic. They took the time to listen to me, assess the situation and give me an immediate quote. Work was performed the next day and I couldn't be happier with the results! I would recommend this company for any plumbing or septic problem. Mike, the owner, is knowledgeable, professional and a cut above any other plumbing contractor I've dealt with in the past. Call them!"

"We had a significant leak from our gas water heater in our garage requiring replacement. Superior Plumbing responded rapidly to our request for help. Shane was very helpful and replaced the water heater in just a few hours. Great service and we will use their services again if the need arises."

"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."

"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."
