One call, appointment scheduled and Sean showed up right on time. Sean used a camera, showed me the sticks and nesting materials inside (serious risk for carbon monoxide not exhausting), did a full clean out and best part, was able to save the cap and re-secure it. All for an extremely good price. Send your business to this fantastic company, highly recommended!!!!

So we will go this winter unable to use it per code. I will say that the technician that came out was very knowledgeable and did a great job cleaning it.

I learned a lot of things from my Dad-- How to be fair, how to work really hard and do more than is…read moreasked of you, how to be generous: I did not learn that if you have a fireplace and use it regularly, even if you always use hardwood, you will need to have it cleaned regularly. So after twenty years of making modest hardwood fires, I started to have a cough. My sister came to visit and even being in the living room (no fire) made her cough and gave her a runny nose. Thinking, okay, I'll have my chimney cleaned, I called Chicago Chimney. Toni was nice and said that Mario was really good at his work, and it would be $150. When he came, pleasant, personable, and clearly competent, I could see that being near my fireplace was making his nose run. I told him about my sister. Might need more that just a cleaning, he said. He shone his flashlight up a short ways into the fireplace. "I call that black glass", he said. What is it? I said. My English is not so good, he said, underestimating his excellent skills. Google clarified. I found out that bubbles of "black glass" represent the third stage of a serious creosote problem-- first soot, then tar that is runny, then the glass part, beautiful and perfectly ready for a chimney fire. One thing about my dad, he prepared me to know a good person when I saw him. Mario said that he was going to have to come back with material and brushes that could dissolve the creosote. The next day, when forty or fifty pounds of mortar on the chimney lining just fell off piece by piece once the creosote was not holding it all together, he explained that another day and another step would be involved, putting a mixture of protective covering over a now very porous surface, insulation, sealant. (As it happened, he did this himself by crawling up into the tight black space and painting it on. The dilemma of having a helper who was unwilling to do it was a problem he would deal with later. He took the guy off to another job and came back. It was this part, where he was a matter of fact about doing the exceptionally nasty work, and understanding about the kid's inability to do it-- he just said "last winter I was doing this every day." I want to put a sign up in my yard for him and his professional and humane work. He charged me $900 for the cleaning part and $1100 for the resealing part. Interestingly, this is less than $150/ year for 20 years, not even counting inflation; I recommend him wholeheartedly for yearly (or every-other-year sweeping) and for the whole cleaning and sealant job if you are someone who didn't know how bad it could get. He does tuckpointing too. The warmth and charm apparently come free.
