H.M. Flagg Tree says it has provided tree care to residential, commercial and municipal customers since 1977. Its website lists a service area of fifteen towns, among them Ayer, Groton, Harvard and Westford. A 2023 customer who had H.M. Flagg remove large amounts of trees several times said Zach worked with them so they were clear on their options, and arranged police details to manage traffic. A 2023 customer said Zach pointed out the strengths and concerns for each tree, with no pressure. A 2025 customer said Zach and his partner cleared a couple of trees on their property over the winter and called them communicative and thorough. A 2023 customer said they got the quote within a day or two of their email and the job was complete in 5 days. A 2024 customer said Zack and his team handled trimming, cutting, clearing and chipping. A 2024 customer said they were safe and worked hard in a timely manner, and that the owner was professional and honest. A 2021 customer said they cleaned up after themselves.
“Tree removal crews jumped into action after a slew of trees fell across the area. Zack Flagg, of HM Flagg Tree Removal, was quick to help Friday.”
Zach and his partner did a great job clearing a couple trees on our property over the winter. Highly communicative, professional, and thorough- I’d gladly work with them again!
Zack and his professional team get the job done with the right equipment, skill and knowledge. They provide considerate, knowledgeable, efficient service skillfully trimming, cutting, clearing and chipping carefully and conscientiously. We've been entirely satisfied with their consistently high quality work and confidently recommend them.
I’ve had a lot of trees taken down in my yards over the years and no one did it better than this company. They were safe and worked really hard in a very timely manner. If I have any more threes in the future that need to be taken down, I will only call this company. They are fully insured and beware because there are some that are not and if something was to happen, it’s gonna be on the homeowner to pay up. Awesome job guys. By the way, the owner was great to deal with because he was very professional and very honest…. P. Perry
Awesome crew. Have worked with them twice now and they’re incredibly efficient and respectful. Plan to work with them again in the near future.
I can not recommend HMFlagg enough. Excellent price, excellent service, and excellent customer service. Got the quote within a day or 2 of my email and job complete in 5 days. What a turn around time. So grateful. This is my second time using HM Flagg and it was the same gentleman doing the work so they must have a good working environment with longevity. Thanks to Jason and team for the hard work
