They came to clean out our chiminey last fall, and there were three guys--the cleaning took no time. When we discovered we needed a chimney cap, they ahd the part within an hour and it was fixed very quickly.
Not only was the service quick, these guys were professional, and polite. They cleaned up after themselves and were pleasant to talk to. I would highly reccomend Top Hat if you need your chiminey cleaned or if you need any repairs.
