Recent Review: Great, very professional. I set up the appointment 2 weeks ahead of time, due to my own time restraint issues. Jon, the President and Owner scheduled the original appointment, he called the day before to confirm time, then he called again the day of the appointment to say they were on their way. They were 5 minutes early - awesome. Worked quickly and professionally, identified the cause of a small leak and fixed it, thoroughly cleaned the entire chimney (and there was some pretty gross creosote in there!). Gave me some good advice on yearly upkeep. Cleaned up so completely and well that after they left you wouldn't have even known they were there except for the sparkling clean fireplace. Jon uses an industrial wet/dry vac to clean up all debris. I will definitely use again and would highly recommend.
