I've hired Energy Attic for two separate jobs - the first was to install a solar vent and some soffit vents, along with adding insulation. The second was installing a radiant barrier. In both cases (two years apart), they were amazingly professional, easy to work with, and the results/savings have been significant. On top of that, any time I've had a question - even if it involves an area that they didn't work on, such as a sealant that was used by my roofer - they were quick to respond and come out to offer advice/help. I think very highly of this firm and would absolutely recommend them to anyone.
