Excellent service and good communication and reasonable pricing




Ivan was very friendly, provided very good communication with regard to what he was doing and what he was looking for with each of his actions. After we answered several questions regarding the problem he went under the house to check the plumbing to make sure it was according to code. When he came up, he assured us that the installation was completely according to code and had been done by professionals. He facilitated a camera exploration of the sewer pipe to find problems that were causing the backup in our sewer system. After showing us what was found and explaining the causes of the problems he explained what he could do to resolve the problem. After he cleared out the problems in the vent pipe and the sewer pipe he demonstrated how everything was back to optimal operation. We then reinstalled the new toilet that we had purchased and all is working well. His thorough explanations regarding the problems and the solutions made us very comfortable with the whole process. We were very satisfied with his work and the price that was quoted after the initial assessment.


Great service




Ivan was very helpful and honest. This was a fast turn around time once I called the main office I got another call 3 minutes later saying a plumber was on his way.


Friendly, Fast and Efficient




John was prompt, friendly, and informative. He walked us through what was wrong and how to best correct it. After his bid he was able to stay and fix our furnace!


Excellent Service




They were right on time which I appreciated. They came in and diagnosed the problem and got it cleared for me in no time. I appreciated the fast and efficient service that they provided.


Great Experience




Having Mike Diamond plumbers replace a toilet and fix a frozen value just gave me peace of mind knowing that it was done correctly and especially in a timely fashion. Very professional!


Mike Diamond




Great and reliable service!


Excellent work but extremly expensive




Mike knew what he was doing and was very careful in his planning and execution of the repairs. He was pleasant to have in the home and did an excellent job.


Excellent, professional service




We were provided an estimated arrival time between 9:00 AM and 1:00 PM and received a call at about 9:00 AM that the job John and Jake were running into unexpected problems and that they would probably not get to us until 2:00 PM. We appreciated the notice and it was no problem for us. They showed up shortly before 2:00 PM and immediately checked out our flow problem. It turned out that we did not need the cleanout of the waste pipe that we had requested. They showed us the problem and recommended the toilet be replace. Then they immediately got to work on the flushing of the tankless heater. John explained each step of the process as he did it, thereby giving us a clear understanding of what was being done and showing us the results. Because we had purchased the cleanout kit when we purchased the heater, there was no charge for their service. John and Jake were clean, professional and we were provided with excellent communication throughout. We are very pleased and don't see why we would call anyone but Mike Diamond in the future.
