McMahon Plumbing & Heating

Maura M.

Our hot water heater broke on a Sunday and our basement was flooded. We called several plumbers and McMahon's was the only company that got back to us that day. They were prompt, showed up when they said they were going to, and very quickly determined the solution, which, unsurprisingly, was to replace the water heater.

They arranged to come back the next day and install a tankless water heater. We had been anticipating this cost, as our previous water heater was near the end of it's warranty, and were very familiar with the typical pricing for installation for a tankless water heater, which is not cheap. The price that they quoted us was within a normal range - a bit higher than we had been quoted by other folks, but considering that it was an emergency situation and they worked extremely quickly to do a big job and replace our water heater to an upgraded version by 2pm the next day, it was worth it.

Everyone we spoke to was extremely professional, patient, and helpful. Adam was awesome and Adriana helped us out a ton, including arranging a follow-up visit to follow up on something. They also were very fair about service charges.

We would definitely recommend them and use them again.

So even with a screen cover, my shower drain was barely ""draining"". I tried to unclog it with a plunger (not the same one I use for the toilet) to no avail. I didn't want to use a harsh chemical solution, so I decided to bite the bullet and use a real drain service. The guy from McMahon arrived quickly, and understood that my building, which is ""garden style"", over 50 years old, and has 15+ units can be a little ""delicate"". I was concerned that the fix might damage the older pipes, but within 20 minutes my shower was draining like new, and there were no issues. Now I just need how to figure how out how to prevent the shower from getting clogged again!

We just bought a condo and we had a faucet leak. They came and fixed the water leak. They were professional and work was completed.

I called for a plumber to come check my kitchen sink which had a leaky faucet and the garbage disposal seemed damaged. A plumber came by and a $99 service fee later, he found something stuck in my garbage disposal and that was solved. Now, my faucet was a different story. I was quoted $800 to rebuild my faucet, $650 if they provided a new faucet w/installation, or $350 to install a new faucet if I decided to buy one on my own. A few days later I called, after purchasing a faucet, I was now quoted $450 to install it, plus another $99 for the service fee. Another service fee was upsetting enough, but having the previous plumber deny he quoted me $350 sent me over the edge. I told the gentleman who came out I would pay the $550 but I will NEVER use them again. He called the office and got back to me that they would waive the service fee and just charge me the $350. I wasn't happy though. Playing with numbers and trying to take advantage of me left a bad taste in my mouth.

A few years back one of their HVAC Techs broke my thermostat. He promised to come back and give me a new one. Two weeks passed...nothing. I called the office and they sent someone to replace it. I was disappointed as they replaced my thermostat with a used, raggedy thermostat. I should have known better to call them again. But my heating system hasn't given me problems so I let that slide. Now I wish I'd read the reviews prior to calling them.

I've had Adam to my home twice now for different jobs. He is phenomenal! So courteous, knowledgeable and professional and describes the job in a manner that is understandable when you don't know anything about plumbing and heating. Adriana in the office is great too! She always follows up when the job is completed to make sure you are completely satisfied. Hard to find these days!

These guys have done two jobs for me now. They came out to inspect a hot water tank leak and do maintenance on the hot water system. They were on time, professional, and respectful. They found the tank to have leak and helped me get it replaced for free under warranty. On the second trip they did a large day long job, replacing the tank and fixing another problem that came up. The owner worked with me on a price that was fair. Adam was my technician. He was great and you should request him. Quality of work was excellent, they left the work space clean and even out in protective boot covers so they didn't bring a mess into my home.

I called and scheduled an appt and was told it was $129 just to come to the condo and give me an estimate. I needed the work done quickly so said okay. I need to have the faucets installed on a kitchen and bathroom sink (and I had purchased those already) and have the drains installed and supply lines installed.
The technician arrived and spend 10 minutes looking at what I thought was a simple job and told me that the cost would be over $1400! I questioned the technician but basically he was following the program on his iPad. I called McMahon's office and questioned them and they told me the project was more involved that what I thought and that they would have to rearrange the technician's afternoon because of the time it would take him. They also agreed to take off the $129 fee for come to the condo to give me an estimate. Bottom line: He did the job (probably in a little more than an hour (acutal work) - he did say he had to get parts from a plumbing house and grabbed lunch but was also on the phone constantly with other technicians. He also did install some trim work on the shower fixtures (and he told me he should have charged me for that but didn't). I was in a situation where I needed the job to be completed that day but I have learned my lesson when it comes to planning ahead.

I only recommend this company if you are pressed for time and no other plumbers are available. They will advertise as a local south shore company but they are in Hyde Park. When your mission is clearly to overcharge customers you will always be looking for new ones. Trust me. this is a company you only use once. Most local plumbers charge much lower prices to establish a customer base and do not drive 30 miles out of their location. Beware of this company. On the positive side, Adam was very experienced, professional and would be very successful as an independent contractor.

FEMALES BEWARE. This company is not truthful, will take advantage of young ladies who they assume don't know any better. Thank God I got a second opinion- saved me THOUSANDS of dollars. Notice all reviews are either 1 or 5 stars? Their reviews are full of either family/friends, or honest consumers trying to warn the public of this company.
