"This is a well-known business in the Vassalboro area. I've used them for tree work twice. I know 3 other people who have used them and were very happy. If needed, they have the skills to do complex tree work, near structures and power lines. Nice people. Easy to work with and competent."

"They were skillful and very professional, and certainly know their business. The crew was very careful about our buildings and power lines and solved some extremely worrisome tree problems for us. Their cost was a little high, but I guess that's what you have to pay for good technology and safe, skillful, energetic work!"

"Two professional young men arrived on time. Were accommodating., steady, and complete. They did a nice cleanup. They loaded the branches on the truck instead of chipping them much quieter. Also they climbed the tree instead of showing up with a bucket truck which I think may result in a more thorough job."

"Robbie is great, he did excellent work and went above and beyond to make sure everything was done perfectly in terms of timeliness, quality, and cleanup. He also had very reasonable pricing compared to two other tree services. He is courteous and conscientious, a great combination that is something every homeowner likes to see from someone they hire. He and Bob cleared 7 trees for us, they left small logs for us for firewood, cleaned up the entire yard and even the roof afterwards. They also filled in all ruts in the lawn that were unavoidable given the work performed. I really can't recommend his company enough!"

"Leo of Arbor Tech did a superb job. He cut the trees down avoiding damage to housing in the immediate area and proceeded to de-limb them. We made an agreement that I would be responsible for removing various limbs and brush for a reduction in costs for the work. We found Leo to be a conscientious & professional worker who communicates cordially & respectfully while accomplishing the task. We would recommend him to anyone in need of tree work, regardless of the type of need. No tree work is too complex for Leo."

"My husband I (Judith), chose Jacob with Treewise for several reasons. He spent time with us giving us a free estimate. We looked into another company and the estimate was the same but they were going to use a bucket truck. Jacob climbed some very large trees on my property and cut off branches hanging over our roof. Its a 3-story house. His partner on the ground collected the trimmings and put them in the truck. The work was done very quietly. Jacob knows his trees! He thinned out an Ironwood tree and trimmed a white pine so that Hinoki False Cypress would get enough sun and he cut down a small oak tree. He was wonderful! A true arborist who knows his stuff. We will have him back again. A Big Thank you to Treewise and HomeAdvisor as we would not have found him without HA."

Arborists FAQs, answered by experts

Although the terms tree trimming and tree pruning are used interchangeably, they are very different types of tree maintenance. Tree trimming involves enhancing the appearance of your tree by removing unruly branches, providing your tree with ample sunlight and nutrients and prevents unsightly overgrowth. 

Tree pruning helps keep your trees disease-free. This process removes unhealthy growths, dead branches, and other unhealthy parts of the tree. It’s more common for deciduous and ornamental trees but not so common for evergreen trees. To determine which method you need, discuss it with a tree trimming specialist.

Though summer is not ideal, you can do some light pruning during this time of year. Just make sure it’s not excessive. Vigorous pruning will stress the tree and impact next year’s growth. Generally, August to September are the best summer-pruning months, particularly for fruit trees.

The depth of tree roots depends on the species. Trees like oaks and maples can have root systems that grow down 20 feet or more. However, trees that grow in shallow soils will have roots that go only a few feet down. Research how your tree species grows in your climate area to estimate root depth.

You’ll have to balance up the cost, the value of the tree (sentimental or otherwise), and the risk factors. An experienced arborist will help you understand whether transplanting is likely to be successful. The cost and hassle of transplanting a large, well-established tree are often not worth it, especially if the species is fast-growing and easy to source. The decision depends on the age and species of the tree, the conditions in the new site location, and how careful the company is when digging out and moving the tree.

Palm trees are unique in that their roots don't grow straight down; they grow horizontally. Typically, palm tree roots go down between 12 and 36 inches deep. The roots grow far and wide from the base of the palm tree to absorb as much water and soil nutrients as possible. In addition, the horizontal roots are also very strong—keeping palm trees stable and helping them sway during storms.
