Stuart and his company did a phenomenal job with blowing Insullation into my attic. My home had the original insulation from when it was built in the 1950s. I wish I had done this a lot sooner. Stuart provided a professional bid on the project. Was prompt with his arrival and was meticulous about making sure everything was in order. I now have about 19 inches of insulation in my attic where it is before I really had basically none. It’s the best money I’ve spent in a long time and I wish I had done this before now. I highly recommend Stuart and his company.

We are extremely happy with the work that Stuart provided. He was quick to respond to my request for a quote and detailed with pictures of what needed to be completed. We purchased an older home that was in bad shape regarding insulation needed and Stuart spent more time adding vents and insulating the pipes in our attic. His knowledge and professionalism is outstanding and the price for his work fit perfectly in our budget. We highly recommend Stuart of GreenStar Energy for your insulation needs.

Green Star Energy did an outstanding job insulating my attic, and I couldn’t be happier with the results. The price was excellent, the work was top-notch, and the whole experience was stress-free from start to finish. Stuart is incredibly professional, honest, and trustworthy, and it’s great to see him working side by side with his grandson. Their teamwork and attention to detail really show the heart of a small family business that genuinely cares about its customers. I highly recommend Green Star Energy to anyone looking for quality work and exceptional service. Thank you Stuart

2 Thumbs up for Green Star Energy and Suart the owner. Stuart was responsive and provided a great deal of education on the insulation process and what's truly required for my situation. He presented multiple quotes and added some additional options to consider. As a result of his commitment to me and his willingness to educate on every detail - I committed to everything. This company is amazing to work with and maintains a high level of flexibility. Most notable is the proce points - affordable and right in the middle of all my 4 quotes. Consider this company. I had a great experience.
