I have used their service before. The $99 ad is a scam. When the service man came, he said I can fix it, but not for $99. He then drilled a hole in my bath tub drain and told me turn on the faucet in the sink. He then said "now all these will go down to your ceiling." Please don't make the same mistake I did.

We had a technician come out to look at our clogged kitchen sink. he quoted us 1600 but if we paid in cash he would do it for 1400. We live in a Senior community and I really feel he thought he could make some quick money. We had another company come out and the snaked it for the under 100 and I was more than happy to give him a nice tip. Beware of Mike Diamond!

Mike Diamond has great advertising, impressive equipment and professional/competent service members. But after calling in problem, they said I would be charged a $97.00 service call plus $10.00 Gas charge, then would get an estimate for the job, which was just replacing a Flush Valve in a Toilet. I figured it would run about $50.00 for parts and $100.00 for labor. A job I have done easily before, but now due to age and stroke can't get down to work on toilet.
The Estimate came in at $ 650.00 and I didn't have any alternatives when already being charged for Service call. and wife wanted it fixed. The job took all of 20 minutes to do and our Toilet is fixed but I still feel that I was overcharged by $ 400.00. Maybe that is where the "Diamond" comes from the name. It is going to cost you an Arm & a Leg for just a little Gem.

Mike Diamond plumbing did the requested work. We needed them to come out a second time to clear a toilet. Both times justified service calls. However, that is not what I take issue with. When paying, for the second service call, I was told there is a $20 fuel service charge. I was never advised of that charge when I called to schedule the second appointment. That means MD is making and additional $15 on each call. Plus, I was told by the tech that there is a $10 coupon I could use but I wasn't offered that discount for this second visit. MD's $99 offer to clear any stoppage is actually $119.
It not so much the additional money, it's MD's nefarious omission of and non-disclosure about the fuel service charge which is unacceptable to me. I will think twice before calling Mike Diamond Plumbing again. Who knows what additional charges they may slap on the call next time!

I got a quote and was charged 76.00 after I was told over the phone it would be a free consultation. I was FLABBERGASTED to see what the tech quoted me for installing a dishwasher, connecting new plumbing for a fridge (water dispenser), installing a sink, and plumbing for the sink. I was quoted a whopping 4000 plussss! Super rip off, i had a complete bathroom demolition and then remodel for that price, minus supplies. When I tell you my jaw dropped to the floor! Never ever will I ever call nor recommend this company. Super unprofessional to lie about the free quote too.

I called them for a simple plugged kitchen sink drain. The kitchen sink drain is connected to a cleanout connection that is located in the back of the house. The cleanout connection is a straight shot through the main drain to the street. The technician told me that it was a real bad stoppage and could not be cleaned out for $99. It would cost several hundred dollars. He showed me where the water was pouring out of the drain connection from a hose he had in the sink.
After I told him that I was a chemical engineer who designs oil refining equipment, including the piping systems, and gave him a hydraulics 101 lesson, he miraculously was able to run the snake from the connection down the line, and quickly cleared the line for $99. It was a real bait and switch operation. Get in the house, then up the price. We found a local guy who does it for $69, and is honest.

Wow. Trying to rip me off. Don't use these guys. I guess they have to pay for all the radio advertising. I operate restaurants, and in my life I've never seen a bill this high when we have issues at my restaurants. They are not looking out for the working class. $2,000 for something that another mom and pops plumber would charge $300 to $500.
