I had another one of the companies listed here come out to clean my chimney and check the flue, and they told me the flue was permanently stuck, and would need to be cut out and replaced with another top-mounted flue for around $700. On my neighbor's recommendation, I called Inspector Flue Seau for a second opinion, and they came out and showed me how my flue was working fine! They also told me that if I had needed the new flue, they would have charged about $300, since I already had the right kind of cap for a top-mounted flue. They also gave me tips for chimney maintenance and cleaning the hearth, and where to find a new grate. So, in addition to knowing their stuff and having reasonable prices, they are honest, and that's the most important thing. I absolutely recommend Inspector Flue Seau!!‎
