McGuinness Tree Service

McGuinness Tree Service is a family-owned Nashua, NH company run by Shawn McGuinness, with branch numbers reaching into Manchester, Concord and several other New Hampshire communities. What sets it apart from a typical tree crew is the crane: the company built its reputation around large-scale, hazardous removals — a 90-ton crane, ISA Certified Arborists on staff, and enough municipal work that the City of Concord contracted them in 2019 to remove 18 fungus-infected trees, and in 2024 the crew handled the crane work for taking down the tree that became Concord's official Christmas tree at the State House. That scale shows up in the reviews too. Customers repeatedly describe the crew removing towering, hazardous trees close to houses and power lines with precision — one review from 2021 described 55 trees taken down from a single property using crane work, and a 2025 review described a 150-foot white pine and several large oaks removed near a home with no damage to the surroundings. Several reviewers also mention the price: one 2025 reviewer said the quote came in over $1,000 below a competing bid, and multiple others called the pricing fair or reasonable. Not every account is spotless. In a 2022 review, one customer described a sloppy cleanup after a removal — branches left in the driveway, lawn damage they had to repair themselves, and other small trees they said were destroyed in the process. It's the one clearly negative account among the reviews here, set against a longer run of praise for careful, thorough cleanup on other jobs. There's also a wrinkle in how long the company says it's been around: its own website describes more than 35 years in business, while the Better Business Bureau's listing shows it started in 2003 — about 23 years. For a large or hazardous tree — one that needs a crane, sits near power lines, or is close enough to a house to worry about — the reviews here describe a crew set up for exactly that kind of job, though it's worth confirming the crew and cleanup plan up front given the one account of a messier job.
