The knowledgeable, professional and experienced team of workmen for that job (with a special shout to John and his apprentice) arrived quickly to seal the leak and turn off the gas line to my apartment.
Barry K. -
After arriving and determining exactly what was needed the tech left and returned about an hour later with a new tank and all the necessary parts to get me hot water all in the same day. Their work was very clean and at a great price!!!

From the competent & understanding dispatcher Anita, to the excellent plumbing mechanic and helper that was sent, the job was done quickly, neatly and efficiently.

I had a major leak in the bathroom and the drainage pipe blew out under the kitchen sink – two problems at one time. It was an emergency. My building management got in contact with these guys and they totally came through. I hadn’t been able to take a shower in a couple of days in this hot weather. It never felt so good to get clean again. With Anita manning the phones and Roberto as pipe whisperer I think any plumbing problem will be tackled with finesse. Cheers to these guys gals in this wonderful City. I’m out.Jean-Paul N.
