I had a great experience with MCM Plumbing. They responded quickly when I reached out for an estimate and were just as prompt in coming out to repair a leaking pipe connected to my front yard faucet. The service was fast, professional, and efficient and also very reasonably priced. I would definitely recommend MCM Plumbing to anyone needing reliable plumbing work! Will def be my go to for any plumbing issues I may have in the future

Mike came out today to find and repair a faint gas leak in my stove. He was polite, patient and efficient. He was able to find the leak, and showed me the leak (little bubbles). Then he repaired it. There's no more smell! I'm very pleased. He charged a fair price, and I recommend him and his company enthusiastically!

I honestly can't say enough good things about Mike and the service i've received/am receiving from him. He's prompt, friendly, professional and affordable. He gave me a very fair estimate, an honest second opinion and called to go over everything with me. He won the job based on how honest & affordable he was but he gets multiple kudos from me for taking on a big job quickly so that I can close escrow and I couldn't be more thankful that I found Mike and MCM Plumbing. HIGHLY RECOMMEND him!

Great job, great service, MCM Plumbing was able to provide us with a new tankless water heater install and had our hot water back up and running within a few hours. They were able to diagnose the problem with my tankless water heater, I chose the option of going with a brand new unit for a reasonable price.

Second time we’ve used MCM in the last seven years. This experience was just as good as it was seven years ago, which says a lot. These guys do great work all while being punctual, clean, and fair. Best plumbers in Merced, hands down.

Had them come out to fix a dishwasher that was not closing properly, they found that a board was sticking out and rubbing on the side of the dishwasher. They pulled the dishwasher out and shaved off the board. Reinstalled the dishwasher and it works great now. Very quick service and a reasonable price.

Choose MCM plumbing. I had Dutchman come out to get a quote and something didn't seem right and the price seemed too high. Next I called MCM and that was the right choice. The price for the same job was about half and plumber Jose was awesome, very professional. Top notch work at a great price. Easy to schedule an appointment and they get the job done. MCM all the way.

Had a leaking kitchen sink issue and was able to accommodate the next morning. Turned out to be a minor issue with sealant as well as a Very minor disposal leak. He was able to return in short period of time to install it. Also he hooked up freezer ice maker as a last minute add on service!!! Professional trustworthy workmanship, friendly and affordable. Highly recommend to anyone needing plumbing work done.

Issue with a leaky hot water heater. They came out the next morning, fixed the pressure surge tank and said we didn't need to replace or repair the water heater. I appreciated the honesty and the timely service. The cost overall was very reasonable and actually more than fair. Will keep MCM plumbing's contact information for any further needs. So glad we finally found a local trustworthy, reliable and efficient plumbing service

Had an issue with a leak on the side of the house from a PVC pipe underground. Called them on a Tuesday and they came out Wednesday. Took one hour to fix the issue. Very professional, timely and very reasonable. Only $98... I was expecting a much higher bill. Definitely recommend!

After receiving four different estimates for a gas line installation, I decided to go with MCM Plumbing. Mike came out and installed a gas line for my gas stove. He had to install over 24 feet of pipe in the attic then brought it down between the wall behind my stove. His estimated cost was less than half of what the other plumbing companies estimated. I am normally a very skeptical person but Mike was honest and at no time did I feel like I was being sold something I did not need. I can honestly say that MCM Plumbing will do a high quality job at a considerably lower cost.
