TLDR. I would strongly recommend against using this company.
I had a tech come out (two hours early, which is fine because I was there, even though I was not planning on being around at that time), without any representation from Chimcare (no branded truck, shirt, etc) and clean my fireplace insert today. He left a big mess (soot everywhere), left a black scratch in my newly finished hardwood floors, didn't bring paper towel to do the cleaning (borrowed a whole roll, and my trash can) and didn't explain what was done. I tried calling the branch after (3pm local time), and the lady is surrounded by squealing roosters (I have a strong feeling she was in South Asia, and it was morning time) and was very blatantly distracted; so much so, she couldn't answer questions. She had the tech call me back and I missed that call (was repeatedly marked as spam as it was a Massachusetts number). When I called that number back, it went to voicemail, saying no one is there, but that "Chimney Services" is not available (not Chimcare). So, I imagine my tech was a third-party hire out. We later connected and he told me my stainless-steel insert was not cleaned to the roof as it is not required. But this is a key selling point on their website, for the $300 cleaning I paid for.
I should also mention that my chimney is being deemed "unsafe" for use until I have them do a $3000 repair, which was an immediate sell by this salesman who was extremely pushy and did not let me ask questions without interruptions.
