Best New Backflow in New York NY

Yes it was expensive but compared to the company we used before, it was worth it!!! The people on the phone are very nice and the plumber they sent ( Sean ) was excellently thorough and really nice. Would totally recommend!

Very competent.

Unbelievable service!

Great service as always. These folks will save you in a pinch….

HORRIBLE. THE FIRST VISIT HE DID NOTHING EXCEPT CALL THE BOSS BILLY and then CHARGE $409. Next day Billy came hour late stayed less than two hours talked on his phone didn’t concentrate. After a day my boiler went out. Billy told me to call someone else. I did. New plumber said Billy forgot to turn water back on the boiler. I was horrified. I paid them $900. Then $350 to new plumber to fix their irresponsible work. Do not use them.

Reliable, straight forward, reasonably priced.

My toilet was leaking constantly and wasting a lot of water. The plumber arrived and repaired the toilet. Very happy with the quick and efficient service. Will use them again for any of my plumbing problems.

Good people they left they card in my store a call them the send some one pick it up ....!!!?

Our pipes backed up in the basement. I called them at about noon and they we're at my house in an hour. They we're courteous, explained everything, and fixed the pipes pronto. The total cost of the job was $212 and it took them about 20 minutes to do it. Would most definitely use them again!

Manny was very informative and professional. Will use again.

Called many companies before dealing with David...they had the best price and they did everything as quick and painless as possible. Great company, great guy! Makes other companies look bad!

They are extremely responsive and efficient. They also don't overcharge for opinions or smaller work like some places do. We definitely will use them again!

Great plumbing company quick and reliable and will work with you on pricing

I am a super and i have been using demar for years. They are reliable whenever i have emergency. Plumbers are clean and professional.

Had the most pleasant experience with this company when my building management was being absolutely horrid. Actually the best, moved stuff around for us and accommodated with the multitudes of red tape my building has. Wayne was the best he arrived ten minutes early and stayed in the lobby for a whole hour because of paperwork issues and was just so nice and patient. And he got everything done efficiently and well timed. Could not recommend a better service.

Anthony installed a new copper water line for me today and he is very professional and extremely very nice. He knows what he is doing and if I know anyone that needs plumbing work done or any of their services to be done, I will definitely refer Anthony to them. Toni
