    Christian, Dominic and their team fixed major safety and structural issues with our chimney that were missed by our home inspector. They were at the house starting to work on this the same day we signed off on the work order and were done by the following morning, promptly getting our house back to a safe state. They were very friendly, professional, and did great work on the chimney system. We highly recommend this company for any chimney related needs!

    Spencer came today for an inspection and was very friendly, helpful, and clearly explained everything so we are fully aware of our options for the work that needs to be done.

    I cannot recommend this team enough! They arrived for a free inspection and were incredibly thorough. Using photos of our chimney, they clearly explained that we were missing a liner—a serious health hazard—and showed us exactly why the structure needed to be rebuilt. Their transparency and expertise were impressive, but their efficiency was even better: they managed to install the new liner the very same day. The crew was fast, polite, and kept us updated throughout the entire process. If you want a company that is communicative and truly cares about safety, look no further!

    I strongly recommend this company having worked with them twice over the last 9 years or so. Recently, a thorough inspection of our chimneys the team at On Duty Chimney Masonry Stove revealed why we started getting smoke in our house this past winter when using our wood stove. The crew explained what was happening clearly and showed photos of the inside of the chimney. The breakdown of the work to be done was super clear. It was nice that they waived the inspection fee because we agreed to have them do the work. The next day they started putting a stainless steel liner in the working chimney and rebuilding the brickwork and waterproofing the top of both chimneys. They repaired the damper latch on our wood stove and they safety tested the stove and repaired chimney. The crew was great about informing us about arrival and departure times and cleaned up everything. Last but not least they were super nice and friendly and willing to answer questions. I strongly recommend working with this company. Addendum: A few weeks after the chimney repair folks left, the roofing on the ridge of the roof near the chimney started to come off. On Duty Chimney Masons sent a team member (Steve) out right away to tack it down. I really appreciate their follow up and attention to detail!

    This is the second time I’ve used this company, On Duty Masonry Stove. The first time was a year ago when I had a creosote clog in my freestanding wood-stove. My first interaction with the company was Grace. She is professional, very knowledgeable and just a joy to talk with. When I asked to talk to the owner, she immediately transferred me to Brian. He was genuinely interested in what I needed to have done and we spoke for 40 minutes. He explained his business, discussed his background and how he performed jobs. Straight forward to the point, no gimmicks, no hassles, no hidden cost, not the least expensive, but the BEST. Minutes after talking to Brian I received a text with Jon’s picture, and confirmation of the date and time. Upon arrival Johnathan (Jon), introduced himself, went over the SOW and began examining my three chimneys, took pictures, and proceeded expertly to clean the chimneys. Periodically checking with me on his progress and any issues he had or taking time to answer my questions. Jon spent 4 1/2 hours working diligently, professionally, very cleanly, which as you know is almost impossible when you’re cleaning a woodstove, and removed the clog. Jon was conscientious, use common sense in his tasks and thoroughly completed the job and left the premises CLEAN. Jon’s a great guy and left not an ounce of dust or debris in the stove. Less than a year has passed since that first cleaning. Two weeks ago, my stove mysteriously stopped drafting almost overnight. I called talked to Grace. We had a nice conversation. She transferred me to Brian. I told him what happened. He said I’ll send Jon out tomorrow. Jon arrived, in a great mood, greeted me with a smile and solid handshake, on time with a new employee, Jimmy. Jimmy was 1 month on the job, looked you in the eyes when speaking to you and wasn’t distracted from his task while answering any questions. Jon worked outside, while Jimmy started to clean inside. Jon quickly found the origin of the draft problem and told me what it was and we agreed on a solution, which they implemented as soon as two other, On Duty employees, Christian and Dominic arrive with the parts. If my memory serves me Dominic was Jon’s mentor and it showed. His professionalism and business acumen stood out, as did all four of them! I was impressed by both Dominic and Christian’s up beat nature and professionalism. They knew this job was going to be another successful completion and happy customer. I love to see that in employees because, it exudes confidence and solid business practices coming from the owner’s leadership. Now I had four employees on the job and I was wondering what the bill was going to amount to. However, I was assured it would be fixed correctly and draft properly. They installed the new base plate and cap, cleaned out the entire chimney, while vacuuming the creosote and debris, so it didn’t enter the house and completely vacuumed out the wood stove of ashes and unburnt wood. Moved the stove back into place, reconnected the flue and packed up. They’re policy is payment upon completion of the job so I went out an ask Jon for the invoice and he told me, “Brian covered this for you”. When I called Brian to ask why he told me. We stand by our job, QUALITY, done right the first time is very important and I feel we may have missed something so I made it right. That Ladies and Gentlemen, made me a forever client of ON DUTY CHIMNEY!!! If you want your chimney cleaned professional, with honest employees who love their jobs and support staff that are fun to talk with call ON DUTY CHIMNEY-MASONRY-STOVE.
