"Javier who owns Dixie Insulation was very professional, and went out of his way to make me happy. I must admit, I'm very picky, but Javier's crue were punctual, and did a first class job. I had my old insulation taken away, and I went with the hard foam. There was hardly any smell, which I read, was because, it was properly mixed. I had one, or two small issues, in which Javier took care of them immediately. I highly recommend Dixie Insulation!"

"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."
