JM Plumbing & Heating

Our boiler was leaking so we needed a replacement quickly. JM was fast, easy to work with, offered a number of options, and had competitive pricing. It’s been installed for a month and we’re pleased.
Our one complaint is that it appears they helped themselves to the laundry basin I use to hand wash delicate items, presumably to empty the radiator system, and ruined it. They should bring everything they need to do the job—or should have asked what they could use. It’s now permanently dirty and stained (I tried cleaning it) so I obviously can no longer use it. Ugh.

We were experiencing difficulties with our new high efficiency boiler system. JM quickly resolved the problems. They were courteous, prompt, knowledgeable, and efficient. I could not be more pleased.

My old Rinnai tankless water heater started leaking at the end of December, and we had no hot water at all by Friday, December 27th. I called JM Plumbing on Monday, December 30th. By 8:00 am the next morning - New Year's Eve day - I had a crew at my door ready to install an entirely new system (which required new piping, venting, etc.) The men were prompt, efficient, professional, and unbelievably helpful. I couldn't be more pleased with the job they did. Thank you Nick for making sure my family starts the new year with hot water!

I had major work replacing an old Furnace/ hot water tank and a water leak detection system. This company is very skilled with very knowledgeable and proficient employees. I would recommend them and use them again when needed.

Nick and his dad and Dmitri have worked on 3 different projects at our rowhouse in DC. The results are always beautiful, and we now have lower bills with our tankless water heating system.
They even saved us from a leak in the basement on very short notice
Happy to recommend them!

Two technicians serviced our tankless water heater. They were punctual, courteous, left everything clean and, as far as I can tell, did a thorough job. The service was not cheap but then nothing plumbing-wise every is.

I’d give Nick, Dmitri and team 10 stars!!!!!!!

I had a particularly difficult replacement job on my 15 year old Rinnai Tankless Water Heater which was very poorly installed by another company. Completely inaccessible, wonky piping, wonky exhaust, gas line sticking out, NO space to work in in a tiny DC row house built in 1908.

They came up with a brilliant solution installing a small wall and moving the new Rinnai to that wall which made it completely accessible. They rerouted pipes and gas line making them more logical and out of the way as much as possible.

They were also unbelievably responsive. Used drop cloths, cleaned up and removed trash.

Seriously outstanding work!!!!!!!!!!!!!!!!

Nick and his team, including Dmitry and Ziad, installed a minisplit ductless heating system on the lower level of my DC rowhouse this week, in the midst of the frigid weather we’ve been having. The team was highly knowledgeable, competent, polite, and professional. They even helped my remove my Xmas tree! Nick’s pricing was also very fair and honestly, customer service is so important with these kinds of jobs and his team was superb. I highly recommend them!

We had JM Plumbing install a tankless water heater in our DC row house. It was a bit of a tricky installation, and they did an fantastic job. Very professional!

Fabulous is an understatement. JM Plumbing found a solution to our design problem that had other plumbers shaking their heads no. In short, we wanted to replace a hot water heater under our stairs with a tankless heater and gain a bit of room for a pantry in the process. Nick saw the problem others saw but then looked around the house and discovered he could put it in the crawl space in our attic. His four person crew showed up at 8 a.m. on schedule and stayed until 9 p.m. that night finishing the plumbing and, incidentally, also adding a whole house humidifier. That wasn't enough time to fine tune it though, so two members of the crew came back the next morning and finished up the heater settings and explained everything to us about maintenance and operating. When after a couple of days of operating the humidifier, we noticed some burping after it started up so his crew returned and fine tuned it as well. So now we've got a tankless heater and humidifier out of sight and more space than expected for the pantry. JM Plumbers provided us with a detailed breakdown of everything they would do and the cost before showing up and they adhered to the plan. Best plumbers we've found in several states.
