I called Jason for an estimate and ultimately chose him. He was the most responsive contractor I have ever dealt with – called back promptly – appeared on time – all the things that you wish every contractor would do. They installed new sink/faucet, replaced pipes under sink, installed a new water filter under the sink, installed baseboard heat in the kitchen. Everything was done as planned, and bless him, Jason and his staff always cleaned up meticulously after their work was done. Overall, there is no question that Jason Green met all my expectations and more. I have recommended him widely to friends. I even recommended him to install the new gas heating system at the local Historical Society where I served on the Board. Recently I had need for a minor repair of my kitchen faucet and again, Jason responded in the same professional manner. That says to me that whether the job is big or small, he will respond in a timely manner and provide the service and results that customers want.

Green Plumbing is extremely meticulous, used top-quality components and parts and does a very neat and efficient installation. In addition, Green is very polite and have a great work ethic. They called the previous day to advise of their arrival time. They were there when they said they would be and put in long work days. The work is extremely professional and neat – really nice work. I believe Green Plumbing is extremely neat in what can be a somewhat dirty kind of work, the work area was mopped frequently and on the occasions when one of the installers came into the main part of the house from the work area, they wore shoe protection to minimize any dirt being brought into the house. My wife and I cannot be more pleased with the installation and we have already recommended Green Plumbing to friends.

Mr. Jason Green and his employees are the best service bussiness we have ever had the honor of being involved with. Jason did all and more work for far less cost then three other local estimates we colllected. He was really experienced with our steam boiler install and made the system run like it never has in 33 years. We highly recommend any interest being directed to at the very least allowing Mr. Green a estimate appointment. He is impressive with his knowledge of energy saving systems. Jason talked with us about information that we had never realized about our steam boiler system so we may extend the lifespan over the coming decades. It was definitely a positive experience.

Spoke to some of your references last night. Do you pay them or are they cousins? Was like asking if Leonardo Da Vinci’s work was OK. Not kidding, once they started talking about you I couldn’t get off the phone! You have certainly made an impression—and rightly so. So with that we’ve decided to go with you for our oil to gas conversion. Your estimate was not the lowest by a fair amount but your knowledge of your product, the Viessmann product itself, the warranty, the photos of your very neatly done installations, the ability to vent through the chimney and the personal testimonials about your responsiveness and professionalism led us to the decision.

Hi Jason,
Everything is working great! I could tell when you first came to give us a quote that you were the right person for the job. Your work is impeccable. The gentlemen from NSTAR was very impressed last night and noted to Chris all of the attention to detail in your installation. He pointed out things that you did that other plumbers skip over or don’t do as well. We are so glad we found you! Thank you so much

We want you to know how much we appreciate the great work you did on our kitchen remodel. Everything is perfect – thank you again for helping us decide on a sink and faucet. I think we made the perfect choice. Our family has commented on how nice things look. Thank you for your excellent service.

I have found an excellent service person in Jason Green my plumber. He enjoys his work and enjoys doing it well. I am completely satisfied with both the dishwasher installation and the hanging of the new bathroom sink. I would recommend him to my friends and colleagues who want service with integrity!

The fireplace insert is for the living room with the chimney, just above where you put in the Viessmann which we absolutely love. You did a really professional job, it is as beautiful as it is functional. In engineering terms I would describe it as elegant.

I just wanted to thank you again for all of your hard work. The heat is working fine and the new boiler you installed is working great!
