On Duty Chimney was flexible and worked with me as I needed to reschedule my appointment several times. Their associate who came to inspect my gas fireplace issue was courteous and did a thorough inspection. Then, the associate also made me speak to an expert from their office who explained all the resolution options to me. Overall, I am satisfied with their service and would recommend them to anyone with fireplace issues.

We had work done by a different company on our chimney, which to say the least was Shawty work at best.
We called on duty and they came out almost immediately to inspect all the work done by the prior company and immediately identified a series of problems. Everyone was incredibly professional, courteous, engaging, and direct with information about what was wrong and what needed to be fixed. They were quick to assess the situation and had all the latest technology to be able to inspect and perform the work required.
They made the process easy to work directly with them to make sure that all the right equipment and components were used to secure repairing the chimney and put a new cap on. We highly recommend using On Duty as this is a company that is professional and will give you peace of mind for the work to be done.
