Admiralty Chimney Service, LLC is a chimney sweep and repair company based in Merrimack, NH, serving Southern New Hampshire and Northern Massachusetts. The company was founded by a retired Navy veteran — the source of its 'Admiralty' name — and is run today by John Butler, a CCP-Certified Master Chimney Technician and CSIA-certified chimney sweep.
Across 55 reviews collected from 2015 through 2026 on Google, Angi, and the Better Business Bureau, homeowners consistently describe careful, detailed chimney work: liner installations, new mortar caps and crowns, repointing, and masonry restoration on older chimneys with water damage or deterioration. Several reviewers name the same technicians — Caesar, Will, Chelsea, Zach and Eric — recurring across different jobs, describing them as punctual, respectful of the home, and willing to walk customers through before-and-after photos of the work. More than one customer has hired the company repeatedly over several years for annual cleaning and inspection, and one 2025 reviewer who collected four competing quotes for a major repair felt Admiralty's price was the only fair one among them. BBB has accredited the business with an A+ rating, and its current Google (4.4★ from 78 ratings) and Angi (4.5★ from 29 ratings) scores are both strong.
Worth asking about before booking: two more recent reviews, from 2022 and 2023, describe scheduling breakdowns — a missed appointment that was never rescheduled with a callback, and two broken appointments in a row despite night-before confirmations, with the reviewer saying the phone went unanswered. Two older reviews, from 2015 and 2016, describe a technician who left a furnace shut off after a cleaning and a declined follow-up on a gas stove repair that was never resolved. These are a small share of the record, but worth raising directly when booking, especially around scheduling and callback responsiveness.
BBB and Angi give slightly different tenure figures for the company (29 years vs. 22 years of experience) and list two different current addresses (Merrimack, NH on BBB; Nashua, NH on Angi) — worth confirming directly. Overall, Admiralty is a well-established, credentialed chimney specialist with a long, mostly strong track record on structural and liner work; homeowners planning liner, cap, or masonry repairs get the deepest evidence of quality, while anyone booking should confirm scheduling and callback expectations up front.
