★★★★★
“Green Attic was great from start to finish. They finished in one day. Drilling countless holes to install cellulose insulation. The crew covered everything and did as good a job as possible in cleaning up afterwards. A few holes could have been repaired a little bit better but the day was long and hot so I’ll live with it. The results were immediate. Noises I’ve heard for years are no longer. The house is more quiet and the air conditioning seems to be more evenly distributed in the house. My crew was great and I appreciate their service!!”
James Kubik · Google Maps

★★★★★
“The Green Attic crew (Alvaro, Omar, Emilio, Ronaldo) did a fantastic two day job with full replacement of ancient attic insulation on split level, installed new solar fan, opened up the previously covered soffits and added baffles. Day two they insulated our concrete floor crawlspace, added closed cell to the rim joist and finished up the interior attic work. they use plastic sheeting and floor covering while they worked and cleaned up all traces of their presence. As with any major activity, a thorough cleaning is needed for whole house, but it was immediately clear that the insulation was taking effect as our humidity levels improved dramatically the next day. We received quotes from other companies, and felt like Green Attic (Frank was our estimator) had the most comprehensive and professionally presented bid. We are glad we hired them.”
