Not sure where you live but I had an amazing experience with Ashes Away in Middlebury. They cleaned and inspected my chimney (way cheaper than anyone else) and he went up and checked the crown and flue tiles and took pictures so that I could see what was happening. He ended up having to replace the crown and flue tiles and add a chimney cap. He explained every single step and why it was needed, and I ended up hiring him to install my wood stove.
