"Green Star Energy did a very good job. They listened to my concerns about the problems in my attic and provided a detailed action plan to correct those problems. Green Star Energy performed the work efficiently and in a timely manner. I would recommend Green Star Energy."

"As a homeowner it is never enjoyable to have unexpected expenses but Koala made it as painless as possible. Phenomenal service, from the estimate with Max to the installation with CJ and her team. I received quotes from several places and the service and pricing was the best. Honest, thorough, and respectful. Highly recommend if you need residential insulation!"

"Working with Star Companies was a great experience — I liked the fact that they emphasized air sealing around necessary elements in the attic and other providers didn't necessarily focus on that improvement."

"I would not purchase anything from this company. We purchased windows and attic armor from them and it did not go well. The owner sent out installers that have never installed replacement windows before. Not only did they do a horrible job but they damaged our brand new siding. We went through 3 of his installers and the job is still not done. We have terminated the installation contract with him."

"Friendly, professional, and not a single attempt to upsell us. Had an almost fully uninsulated attic, and they did a perfect job! Called when they were on their way, explained the process very well before they started, and in a couple hours went from needing to sleep with 4 blankets to being toasty with one! They even concentrated extra padding right over the bedrooms. Can't reccomend these guys enough"
