Best Radiant Heating Installation in Newark NJ

Professional and was on time! Highly recommend this company.

Nice guy. Quick and efficient!

Very happy with the work Heyrich did for us. They replaced our hot water heater and replaced our old oil burner with a new gas boiler. Great work at reasonable prices. Now I know who to call for any new plumbing issues.

I've worked with this company over the years and decided to leave a review. I have had many positive experiences even as recent as a week ago. Always a pleasure working with people that show initiative and actually do what they say. Recently we hired National to install Gas Piping and provide a pressure test as well. They were competitive on pricing and scheduled and met with the inspector. Piping work looks great and the inspector was complimenting the work and professionalism. Great company with great people.

So i did not hire these people to do anything, it was all the owner of my apartment building. I got a lot of things to list off so #1 these people do not finish their work on time properly. So one Monday morning they barged in and took all the old radiators from all the apartments in my building, and completely damaged my floor dragging them out of my apartment. #2 they are very unprofessional, if you ask them when they would be more or less done they respond with hostility and rage about being overworked, understaffed and underpaid. Which i totally understand, but do not take it out on your customers. #3 they are very messy, they drilled holes through the wall and did not clean up the shavings left behind. #4 about 2 months later after they started said project still it has issues, now they gotta start all over again to see where one of their many negligent employees messed up the water heater piping. I wouldn’t recommend hiring this company in the slightest even if i owned property, they cause more damage than fix anything.

Moses and the entire DMC team has been incredibly helpful through our many plumbing problems. Our builders left us scrambling—improper/counterintuitive installation, backed up pipes, and sump pump connection issues. Moses was patient and took the time to test, retest, and give us options before proceeding. He was always prompt, thorough, knowledgeable, and understanding. After Moses’ 5+ visits and thoughtful solutions, I’m confident in the current state of our plumbing (and learned a thing or two along the way thanks to his teaching). Highly recommend DMC (and Moses especially!!).

Extremely unprofessional. Never showed up to my first appointment to change a valve in my apartment. I had arranged with my condo association to notify the entire building of a water shut off and Haddad plumbing did not respect the schedule. When they did arrive two days later AND 2.5 hours later than discussed, they sent one person instead of the two they originally promised. The plumber asked me to help assist him with the job. I paid $500 for a simple job and I had to help too. Spoke with Alex Tsirulnik at corporate about compensation to which he was of no use. More worried about pocketing the money than customer satisfaction. Would not recommend - find a plumber somewhere else that is professional and respects your time.
