Gramman Plumbing installed a brand new gas heating system & hot water heater. The work crew did an impeccable job and was courteous and considerate. I am sure that I will continue to use their services and would definitely recommend them. I am just sorry that I haven’t used their services before now.

We are very happy with the service provided by the Gramman team. We noticed that water wasn't as hot or even warm enough, so called Gramman (was evening, and after-hours). Nick suggested that he would have someone take a look next day, and suggested few things like unplugging electricity from water heater and turning off water into the heater. Next day got a call little before 8am from them, and they arranged for a technician to have a look within the hour.
Keith, the tech, stopped by as advised by their phone rep. Maria, and gave us a quote after inspecting the problem and speaking with their

Our heating boiler died out the week before Christmas; Bob Gramman and his team of professionals had a brand new boiler installed and running the day before Christmas. In addition under new Village codes the new boiler had to be externally vented which created a problem in our finished basement. Bob’s team of expert plumbers skillfully figured out… a way to vent the system to the outside with minimal disruption to our finished basement. I believe Bob and his team are reputable and conscientious. In addition I found his back office staff to be considerate, courteous, and always very

Gramman Plumbing and Heating is a one stop shop, no need to look elsewhere. They are experts in their trade, the workmanship is impeccable. I hired Gramman for a oil to gas conversion in my house, its a project that needed to be completed to perfection and these guys did not disappoint. They earned every bit of 5 stars in my book. A bunch of plumbing companies on long island and these guys compete with the best of um.

We recently had an oil to gas conversion performed by Gramman Plumbing.
It was a pleasure to have a team, led by Pat, come into our home. They practically laid down a red carpet treating our house like a million-dollar home. The team worked in less than ideal conditions, maneuvering around our crowded dusty basement and leaving it cleaner than… they found it. They left no trace of the old oil boiler and oil tank, and they deftly removed everything without leaving a scrap of anything inside or outside our home. In particular, they respected our neighbor's newly paved driveway, which is located
