Trustindex verifies that the original source of the review is Google. I received an email from Eversource stating that they had sent me a post card with an error on it - the post card said I could get my house insulated with a 100% rebate, but that may not be the case and I should check to be sure. I clicked the link and found JT Energy on the contractor list. I called them - Tom Marchand picked up and we talked a bit, he asked me to send him an image of the post card. Long story short, it turns out I did qualify for a 100% rebate! The crew came yesterday as promised, they worked quickly and efficiently, took good care of my house and insulated all of my exterior walls, wrapping up in the early afternoon. This is a tremendous company to work with and I highly recommend them.

Trustindex verifies that the original source of the review is Google. I was approved for a full insulation on my home through Springfield Partners and JT Energy was the company that performed all the work. I am in awe at how fast they did everything and it all came out great. I had a few leaky spots in my roof that should’ve prevented the attic from being insulated. Hasheem didn’t let that stop them. They came back and provided a long term temporary fix for me, so they could insulate before the fiscal year ended. Not only did they not have to do this, they were happy to. Hasheem, Ben, Alexander, and the rest of the crew were professional, thoughtful, and respectful while working on my home. I’m so very grateful and will definitely recommend your company to others in need. THANK YOU!!

Respectful of property and extremely thorough. The crew was kind and considerate. Hashem, the crew chief and contractor oversaw EVERYTHING that was being done and made sure I was satisfied every step of the way. He kept me well informed of the jobs that were being done and why. The mutual respect between the crew and Hashem was obvious. They had a job to do and did it beautifully. Truly an honor to see. I can't say enough about this company. I never felt ill at ease or skeptical at any time. Kudos to Hashem and his crew. If you want guaranteed good work, hire this company. You will not be disappointed.

Not only was their price very reasonable for our new home, they did a great job installing, they kept the job site clean and Justin was so good about communicating so we’d know what was going on every step of the way! They showed up when they said they would and got the job done! I highly recommend them for your insulation job!

Trustindex verifies that the original source of the review is Google. Our family just used JT Energy to insulate our older New England colonial. We could not be Happier. Their professionalism, commitment to excellence, runs thru the entire organization. It was a big job and they were clean, managed expectations, communicated thru out the entire process till final permitting and finish. My hat goes off (not just to the owners yes) but the supervisor , guys outside, inside, you all know who you are and every detail appreciated. By the time they were nearing an end we weee eating pizza together that’s how comfortable and thankful we were with the process. Highly Recommended! 👏👏👏
