Tyler and the guys who came over to install the new chimney lining did a great job. My only complaint is that I selected 2nd Generation Chimney in part because they touted their 10-12 year warranties on chimney lining and sealants. After the work was done however, I come to find out that this warranty is contingent on getting annual inspections from 2nd Generation (or similar company) at hundreds of dollars per inspection. So I have a little bit of feeling of "Bait and Switch". I don't use my fireplace that often. So creosote or other types of buildup shouldn't be that significant on an annual basis to warrant inspection. Maybe every two or three years ...but not every year. So that was a bit of a bummer.
