Best Tankless Water Heating in Boston MA

Very friendly staff, and very pleased with the professionalism as well as the work done. Staff was great about wearing masks/social distancing during the job as well. 100% would use again.

We did that thing where you wait until the coldest day to turn the heater on... well it didn’t work! Frank was great on the phone and walked me through the checklist for our gas boiler. I sent out a few photos so he could see the type of unit and he called me back to let me know he could be here shortly. Ten minutes later we discovered the pilot light wouldn’t hold a flame and he quickly got the part and we had fire. He was personable and answered any questions I had-made me feel comfortable and confident in his service-and showed up in a mask taking appropriate precautions. We will be reaching out to him to schedule regular servicing of our units.

Repeat customer with McMahon, always satisfied with the staff and the job the do! They found solutions to unique issues we had. Thanks to the Mike and the rest of the team

Frank was very unprofessional, he failed to show up when he schedules to, prolonged the job and was very dis-respectful. He revised the price upward in the middle of job and after we agreed on the new price he did install the sump pump, got paid in full but didn't return to complete what he promised even after several calls, voicemails and texts up to this moment. I had to get someone else to redo the job.

Rich Mathews is really a good HVAC and plumbing expert, very genuine and honest with estimation, work and well organized. We got flooded and the hot water stopped functioning, called so many places, Rich was out on another job, promptly returned my calls, texts and emails. He also has a great relationship with the local town inspectors that is able to coordinate very efficiently on permits and inspection times. He came over on Saturday and got the water heater replaced by Monday, again kept us in the loop with the process. Fixed few things which the builder had forgotten about it during initial construction. He has kept in contact after the job was done to make sure we were runing and if other items related to water damage were getting addressed, highly recommend him, glad that I found my plumber for all future work (Thanks Rich !)

I was pleasantly surprised with my experience with Advantage III. I called on a Monday morning, they picked up right away and were very friendly. I was able to get an appointment the next day to look at a water leak I was having in the basement. The plumbers came and identified and fixed the issue within an hour and a half and they were very nice and seemed to be very knowledgeable. Would recommend!

My gas stove was sitting about 6 inches away from the wall because of a pipe coming out out the floor. Rich moved this pipe and now I don't have this big gap behind my stove anymore. Other companies wanted to go straight to breaking up the stone foundation to get at the pipe. Rich studied the situation and decided to try going at it from the top first. He learned that this would work and that going through the foundation in the basement would not have worked because of the way the pipes were arranged. He got the job done. He seemed very competent and trust worthy. (He also noticed that the sealant around my exhaust pipe from the water heater needed repair and he did it without charging extra for it.)
I would hire him again.
It was expensive though...I don't know if this is the going rate or not...

Very nice gentleman came to the house, he was appropriately dressed for Covid and social distanced, he took a few notes down and a few pictures of my furnace. They got back to me via email to give me an estimate.
I was very pleased them.👍

Vinnie was great. Knowledgeable and a great communicator. Will definitely use again.

The repair that was required, was done so with great swiftness, and the plumber who did so was awesome. He was honest, and I would not hesitate to call him back, and would recommend him to anyone. Thank you

Tom and his crew were friendly, fast, affordable, and did an amazing job. Tom is extremely knowledgeable and offered us many options as we replaced our sewer pipe. He also fixed a pipe leak and installed two toilets - all in a day's work! Plus, my dog is now in love with him.
Thanks Tom!

Kevin was very quick to answer my email and phone call and was able to check our units just a few days later! He did a great job on assessing what was wrong, diagnosing the problem and repairing it. He also was great at explaining the process to me which I really appreciated. I'm so glad to FINALLY have a functioning AC again! (Particularly before summer starts). Thanks again Next Step!

I decided to use this plumber solely on the reviews and that was a big mistake. I have never written a negative review in my lifetime about a business since I also own my business and know how difficult customers can be sometimes. I scheduled an appointment with this company at a certain time but they showed up 4 hours earlier and I was not home. They rang the bell came in did the work in under 1 hour which was a very simple job with very little supplies necessary. They charged twice what the normal cost of the job would be and took advantage of the person who was home just because she was a woman. I gave the business owner a chance to respond to my complaints instead to be called a liar who is trying to cheat them and several other names. They claimed that they charged per hour labor from the time they got the call and left whatever location they were at trying to explain the outrageous price and that I had to pay for time and gas for them to travel to me which I live less than one mile away. Then they said they charge a flat fee for this specific job each time which is false because I explained the job and even texted them a picture and they said that they need to come out to see it to give me a price. They did try hard to explain the over inflated price in which there is no explanation. They even charged in the invoice for the appointment even though they claimed to waive that once they start doing the work. There was no break down of labor costs, cost of parts just a huge total with an appointment charge added on. They said they would offer a discount on my next job or a $50 discount because they know they did me wrong. I feel completely taken advantage of and I was not home to approve this job and it is a shameful to take advantage of women to make profit. I believe in making an honest living. This was not honest at all what they did. Proceed with caution with this plumber.
