We had our attic improved with air sealing, new baffles, and R-60 cellulose insulation. The insulation team also connected our bathroom fans to new roof vents and we added a solar fan to keep the attic well-ventilated. The crew did a great job, with Romulo and Ronaldo as the experts and Daniel helping out. They were very efficient, kept things clean, and did testing to check things out. Gas company rebate helped with cost. Overall, a good experience with Green Attic Insulation and we're glad we now have a much better attic.

Green attic came out and took a look at my mudroom letting me know adding insulation probably would not help too much. They said I would be better off adding a potential duct with vent. I appreciate the honestly and no high pressure sales tactics.

While we determined that I may need to seek additional confirmation as to the possible issue, the person that came out was very professional and gave, what I believe, to be good advice to check on some other things before possibly incurring what could be a large expense.
