Emil cleaned my chimney thoroughly as advertised. He found that there was some damage and that the chimney is not safe to use until it gets fixed.
Emil suggested some fixes, but it was a little hard to understand what the different possibilities were, their approximate cost and what the other trade-offs are.
If he had been more clear about what the different options are, I would be more likely to hire them back to complete the repairs. As it stands, though, I will likely get some other quotes first.
