Our Industry Experience

We have been in business for over 35 years and have extensive experience working with trees in our region of Wisconsin.  Our skilled arborists can effectively diagnose and treat tree diseases, pests, and other problems, as well as provide proper pruning techniques to enhance the health and appearance of your trees. 


Tree work can be dangerous and requires proper equipment, training, and experience to ensure the safety of both the tree and those working on it.  At Colonial Tree Service we have what it takes to complete the work safely and efficiently.
