A-Z Chimney Sweeps & Repairs handles chimney sweeping, inspections, liner and cap replacement, waterproofing and full chimney rebuilds out of the North Shore — self-described as veteran-owned and, on its own website, based in Haverhill, though Better Business Bureau and its Angi/HomeAdvisor listings place it in Danvers. Across 75 ratings on Angi and HomeAdvisor, the company holds 4.6 stars, with 85% five-star. Reviewers keep naming the same people: owner Dan and technician Brett come up repeatedly for showing up early, finishing quickly, and explaining what they found. In a 2021 review, a homeowner described having two chimneys rebuilt — one venting a furnace and starting to crumble, another pulling away from the house — with new caps installed on both; a 2025 review credits Brett with resealing nail pops from separate blasting damage at no extra charge, beyond the original chimney job. A 2022 Reddit thread names the company favorably, contrasting it with a different chimney company the poster called a scammer. The most recent review on file, from April 2026, is a one-star complaint: the customer says a stainless steel liner installed for a pellet stove was used rather than new, and that they discovered it had been cut into three pieces after removing the stove — calling the company "thieves." It's the newest account in the record and worth raising directly. Before booking, it's worth clarifying the company's history and home base: its own marketing claims 41 to over 50 years of experience, while BBB's file — which carries no letter grade yet — shows it as a sole proprietorship that opened in 2010, and the website's Haverhill address doesn't match the Danvers address on file with BBB and the review platforms.
“I just had a great experience with A-Z Chimney. I had Master build come out to put a liner in one of my flues and they put in a flexible dryer vent in and scammed me out of $5000. Stay away from Masterbuild and or Mike Purcell just a scammer. A-z came in put everything in took pictures of everything for me, cleaned up and painted chimney. Can't say enough about them.”
They put in a stainless steel flex liner for a pellet stove, it was used and they charged me for a new one. We recently found this out because we removed the pellet stove and we saw the liner was cut in 3 pieces which is unacceptable. I would not recommend these thieves to anyone.
I could not recommend Brett and A-Z Chimney more. Not only do they do quality work that they stand by, but they're also just genuinely good guys. I recently sustained blasting damage to my 2022 chimney that A-Z did the work on back then. Brett really helped me out on the cost of fixing the chimney damage. He even went above and beyond and hammered back down and water sealed the nail pops from my house settling from the blasting, which were causing additional water damage. Quality work, quality people!!
Very honest company.. only give recommendations based on what is needed. Will do business again.
Very professional. Actually wound up letting me know they could come earlier than the scheduled appointment time. When they arrived, assessed the issue with my pellet stove and cleaned out the flue pipe immediately. They were well prepared and quickly did their work. After cleaning the flue they waited until the stove was running properly. The price for the service was as quoted with no additional charges. Very satisfied.
They were very thorough and very informative.
