Black Diamond Chimney

I had Black Diamond Chimey come out for a chimney inspection on my house which I bought a few years ago. I had never had the chimney inspected and they found some issues with a previous chimney fire and issues with the structure and build not being up to code, causing issues with effectiveness and efficiency with the old wood stove as well. The quote was fair and thorough. They quoted a full tear down and replacement which my insurance company did cover due to the fire hazard. Thank you so much for the help and professionalism. I would recommend Brandon and his company thoroughly.

Brandon is great! He has serviced our stove and chimney three times now. I recommend him to everyone I know! He is really good at what he does. He knows what he’s doing. He is professional, friendly, takes time to explain things, reasonably priced. Invoices are straightforward and easy to pay online, and the reports and summaries he sends are detailed, helpful and easy to read. Last year he went way above and beyond in helping us correct a major issue we had that was caused by another company. I really can’t give higher praise. We are really grateful that someone passed his name on to us.

I’ve been using Black Diamond for a few years and couldn’t be happier. On time, great job, efficient, and fair. Going to continue using them for my pellet stove for as long as I have it.

We had a wood burning fireplace converted to a propane fireplace in March of 2025. We found Brandon's knowledge of the systems and process to be top tier, with competitive pricing. He kept the disruption to the rest of the home at a minimum. My only issue was the lack of communication as we waited for components to arrive. Having put a lot of money down in advance of the project, I would have preferred more timely communication and a more realistic start date upon the initial visit. Having that much money committed with no firm ship dates for components caused some anxiety. Brandon had no control over his supplier (of course), but communicating delays to us pre-emptively would have been preferred, and we did have discussions regarding same; Brandon was very gracious throughout. That said, the workmanship speaks for itself, and I would recommend Black Diamond Chimney to anyone looking to convert their fireplace to propane.

Working with Brandon at Black Diamond chimney was refreshing. He is professional, thorough and takes the time to fully explain everything you need to know. I look forward to working with him again and would 100% recommend him. Thank you Brandon.

Really happy with Brandon and Black Diamond in general. Honest feedback, timely service, and clear communication. Would highly recommend for any chimney service or repair work needed in the seacoast area.

I have had Black Diamond Chimney do some work for me and have been very pleased with his work. Brandon is very professional and very personable. He pays attention to detail and doesn’t cut corners. My dog loves him!

My husband and I had Brandon install a gas fireplace for us and couldn’t be more pleased! Not only is Brandon honest and trustworthy, he is meticulous and truly skilled in what he does! We highly recommend Black Diamond Chimney! Ask for Brandon!!

We can not recommend Black Diamond Chimney enough! All the work is top notch and professional to the last little detail. Even the cleanup afterwards… you would never know they were there! (except for the beautiful new stove) We would not call anyone else in the future!

Brandon is not only very knowledgeable but also extremely professional in his work. He pays great attention to detail and is meticulous in making sure that the fireplace stove is properly installed and functioning as designed..

Brandon and his team at Black Diamond Chimney are true professionals. Not only are their hands-on skills exceptional, their professionalism and communication is superb. They repaired several serious issues in my son’s circa 1900 home and had great attention to detail to make sure everything was exactly as it should be. We will use Black Diamond Chimney for all stove and chimney cleanings and repairs in the future.

Came when agreed, very efficient appeared very knowledgeable, kept area clean, did the job without lots of talk.
Quoted a price and that's what he charged.
Would both recommend and use him again
