"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"Can't say enough good things about this company, an overall pleasure to deal with. The owner responded fully to all my questions and the crew that came to do the work was excellent. The owner stopped by the second and final day to see how things had gone on the first and assure me that he and the crew were only a phone call away if I had any questions or issues. I have another insulation project and I intend to use Koala Insulation and I expect the same results. Thanks for the great job!"
