"We moved into our house in the winter and found out that the 70 year old insulation was quite deteriorated and moldy in the fall. We decided to have the old insulation removed so that we could cut down on heating bills and get rid of the smell. I contacted several companies and interacted with Joe from Good Life as the salesperson. He was kind enough to come to our house twice as the scope of the project changed. Both times, he drafted the proposal right at the end of the visit. His professionalism and the quoted price convinced us to go with Good Life Energy Savers. On day 1, the first crew came to remove the old insulation from the attic and used open cell spray foam to insulate the basement rim joists. On day 2, a second crew came to apply blown-in fiberglass insulation in the attic. Please note that the material they use is not irritant at all. Both crews worked really hard and cleaned up very well after they were done. I was especially impressed with the job 1st crew did to remove the old insulation from the slopes on a cathedral ceiling. My only minor complaint is regarding the patch in the ceiling at the end of the job. The guys used paper tape and there were bubbles all around. I guess they were very tired at the end of the day. Initially, I was planning to paint the room myself to cover the patch. But after removing the paper tape (due to bubbles) and using fiber mesh tape and joint compound, I figured I wouldn't be able to smooth the edges of the patch perfectly and hired a professional. Overall, it is a great company that provides quality job at a reasonable price. With the new insulation, the furnace runs much less frequently and I am pretty sure the job will pay for itself very in a few years."

"My experience with everyone was excellent. It started with an energy assessment followed up with spray foam insulation throughout my home. Good customer service and follow-up. All was explained thoroughly throughout the process and they welcomed my questions. I highly recommend this service."

"This company is awesome! They were professional, prompt, and clean, and the work was high quality. The office kept me informed every step of the way - communication was clear and informative. The installers were very respectful of our home and on completion, we could hardly tell they had been there at all. Most important is that our house is now significantly warmer - nk drafts or cold zones and we already observe that our heating is not continually pumping out heat - the house stays warm all day. This was one if the best decisions we have ever made and we are so happy that we chose Shelton Insulation - thanks guys!"

"Had our roof replaced, looks like a clean install. Trey was easy to talk to and was very assuring. We'll see how the roof holds up against this weekend's snowstorm or whatever's coming our way. Yes I copy pasted my own review from Google Reviews."

"The crew did a fantastic job with installing my blown in insulation. They were punctual and clean. Taylor the project manager stopped by to drop off the insulation before they started and reassured me that I can call him anytime I needed him during the process. Overall I'm very happy with how things went."

"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."
