"Great experience with Juan and his team at Green Sky Tree Services. They did a great job pruning 4 trees, a large hedge and a couple bushes in our back yard. They were on time and did an excellent job cleaning up when the work was done. We will be using them again for our end of year clean up."

"This message is to express our positive appreciation for the professional work performed on extensive tree work on our property. We had multiple tall trees surrounding & overhanging our home (which caused us many problems during last ice storm). Quality Tree Service came out promptly as promised for both the reasonable estimate & followed by the appearance of entire work crew to perform the work, which they did in an efficient & professional manner. We were impressed & pleased with their job! We were particularly impressed with "Francisco"."

"Excellent service. The pruning of the 2nd oak tree and the Hawthorne tree was done one day, and all other work done the next day. The 4-person crew was very professional, kind, and respectful of the property. The large oak I had removed was right up against a new fence, and not far from the side of my house. And, it was not in an area to get a bucket truck nearby. They arrived right on time at the start of the day and worked hard with minimal breaks - very impressive. They ground the stump from the large oak as well as grinding a couple of leftover stumps from previously removed holly trees. Their cleanup was superb! They even blew stuff off the top of my roof! And the wood cut down was nicely rolled together - not just dumped into a large messy clump! And, they were cheaper than another bid I got from a company here on Angie. I cannot recommend them high enough."

"They were very easy to work with, and completed everything in a very professional way. I was really impressed w/ their ability to complete a huge job and cleaned up nicely when they were finished. They removed several giant maple trees. The boom truck was a great success at taking down these huge trees. I was very impressed with their ability to make a big job appear easy. Many thanks to the work that they completed. The tree climbers were terrific."

Tree Service questions, answered by experts

You should prune ornamental trees once every other year after the fruit has matured and begun to drop. You should also prune out dead branches whenever you see them. Pruning too often can stimulate more growth, especially in faster growing varieties like Bradford pears.

The shepherd’s tree, native to the Kalahari Desert in Africa, holds the record for the deepest known tree roots at over 230 feet deep. Some African communities refer to it as the “Tree of Life” since it provides food, shade, and medicinal properties to the surrounding community.

A tree growing close to a house can pose several risks, but removal isn't always the only or best solution. Potential problems include roots growing into the foundation and causing structural cracks, branches damaging the roof or promoting moss growth, and debris clogging gutters, which can lead to water damage. Trees can also provide access for pests and encourage mold. However, a small, healthy tree may not be a problem, and for larger, established trees, strategic trimming can be a cheaper and more beneficial alternative to removal. It is generally recommended to take action for trees within 10 to 20 feet of your home, especially if they are unhealthy or encroaching. Your best bet is to consult a professional arborist who can assess the specific situation and provide expert advice.

In most cases, you should not use a pruning seal on trees after trimming. Applying a sealant can interfere with the tree's natural healing process, and it does not guarantee protection from pathogens. Instead of sealing the cut, the best practice is to support the tree's natural recovery by providing it with plenty of water and a dormant-style fertilizer. However, there are exceptions. Pruning seals may be recommended for very vulnerable species, like elm trees, in areas where dangerous diseases such as Dutch elm disease are prevalent. In these specific situations, the protection offered by a sealant can outweigh its downsides. For advice tailored to your situation, especially after cutting large branches, it is best to consult a local tree trimming professional.

While it’s best to have access to large, healthy, strong trees in a safe position, treehouse living is still possible without them. Contractors can fit tree posts to build the structure onto or use posts as additional support alongside the trees themselves. If you’re in doubt about the suitability of the trees on your land, consult with a local treehouse builder before you start the project.
