This is my first attempt at cleaning my chimney. I borrowed my father in laws brush. Due to the height of my chimney I decided to give it a try from the fireplace because I am scared of heights and don't feel comfortable. My question is this, is it ok to clean the chimney like this? I took the damper off which allowed the brush more clearance and it also gave me a better view of the flue. I thought it went pretty good and wasn't that much of a pain to do myself. I posted a few pics of the process and would like any and all comments on how I went about this or things I could do different. I have an open fireplace and usually burn it hot so I wasn't expecting to see much. Do the pics look normal with what is laying there or should I just pay a chimney sweep $140.
