Attic Star pros discovered rat evidence in our attic, which we had suspected. They came in and in one day removed all the old insulation, sprayed nontoxic spray, installed new installation, covered the crawl space under the house and secured the entry points. They were careful to seal up inside spaces n lay down paper where they walked, etc, too. Thanks to everyone involved; grateful to all immigrants who do this hard work!

Efficiency and cleanliness were achieved during air duct replacement.Posted on Google Ollie NicholsTrustindex verifies that the original source of the review is Google. We had no idea why our winter utility expenditures were going up year after year. It came to light that the majority of the attic insulation had settled, and that certain spots had been contaminated by rodents in the past. It was unexpected how much of an impact the replacement had. Now you can forget about fiddling with the thermostat; the temperatures remain steady.Posted on Google Melissa MastersTrustindex verifies that the original source of the review is Google. Basement had this weird cold, damp feeling year-round that never really went away. Mold remediation uncovered moisture trapped behind insulation panels near the wall framing. Everything affected was removed properly and replaced after drying equipment ran for several days. The space finally feels normal instead of clammy.Posted on Google Janice BoissonneaultTrustindex verifies that the original source of the review is Google. Even with the help of candles, the musty smell in the basement persisted. There was growth under storage shelves that we never moved, therefore it was the appropriate call to get rid of the mold. Without resorting to jargon typical of contractors, Evelin kept us apprised of developments. The musty aroma of the cellar has finally dissipated.Posted on Google Tiffany WebbTrustindex verifies that the original source of the review is Google. I expected a few shocks when I bought an older house, but I didn't expect this many. Major maintenance was required in the attic due to polluted insulation and decaying ducting. To ensure that we tackled everything in the correct sequence, Tom provided explicit instructions regarding the priorities. Now the house has a whole new vibe about it.

Attic Star did a fantastic job on our attic. Attention to detail, professional, personable, and a clean job, great company. They get all the debris out, clean, close up openings and install insulation. They did not leave any debris in or out of our house. They also take pictures so you can see the results. Highly recommend.
