"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."

"Master Attic removed my old and rodent infested insulation, thoroughly cleaned out all the junk in my attic, vacuumed all the dirt, debris, and rodent feces, sealed all air leaks, installed rodent-proof cages around any entry points to the attic, sanitized the entire attic space and installed new insulation throughout. Francisco and his crew were fantastic! Great job by Master Attic! Thank you!"

"Unfortunately, when the techs started the process, the insulation already in the walls prohibited the addition of the foam. I cannot begin to tell you how disappointed I was, as the job they had done on our tiny addition was remarkable. However, isn't it wonderful to have a company tell you the truth!"
