"I wished if it were be able for me to give this company more than 5 stars for my review. Right after I realized that we have Raccoon residence in my attic I sent an email at midnight to Attic Fanatics. I got a call at 8 from Coby who said someone will come within a hour. Mike Bruer showed up on time and did a thorough inspection. He advised me that the Raccoon may have been in my attic for awhile. I decided to replace all insulation. He provided me a reasonable quote which I accepted right at the spot. He also helped me to file a claim with my homeowner insurance company. On the very next business day there was a crew of 5 people showed up on time. They are very professional and did a neat job. Being a picky person like me I am totally satisfied of their work. They sealed the openings to prevent the Raccoon from return. After they left I found out there is one Raccoon was still in the attic so they came back right away and chased it out then resealed the soffit vents with heavy gauge mesh. Great job!"
