Christian, Reed and Dante were all awesome. They were very pleasant, knowledgeable and very polite. They made sure that although it was a very dirty job they protected the rug and all the surrounding areas. You are very lucky to have them as your employees. They explained how to use the new heating insert and made sure I didn't have any questions. I would definitely recommend your company to anyone needing chimney help. Thank you.

I want to thank On Duty Chimney for a very thorough job. A previous service did not have the technology to send a camera up through the system and reveal serious problems that would put our home at risk, but your service did. I was given a very realistic appraisal which was very valuable. I will happily recommend you all. Thanks again. JC

We have had frequent, seasonal visitors to our gas fireplace (birds). We’ve called On Duty several years in a row and they’ve been great at cleaning out the vent and evicting the squatters. Hate to kick the birds out to the cold but this is a huge fire hazard ! The only problem is they book out so far so you have to wait for an appointment but that goes to show how busy they are and in demand. Highly recommend and great customer service !!! thanks again!!
