We Follow Industry Standards

We adhere to the standard ISA (International Society of Arboriculture) regulations of removing dead wood, water sprouts, and structurally deficient branches for your trimming and pruning needs. We also take great care to preserve the aesthetic value of the tree(s) to provide a healthy tree devoid of scars or potential disease-causing wounds.

Our Services


Trims are necessary when the limbs are in close proximity or actually in contact with a structure or utility lines. Removal of damaged, diseased, and dead limbs will significantly contribute to the health and structure of the tree.

It is also proactive by preventing potential damage should one fall. Trims are also prudent when an increase in the amount of sunlight reaching the ground is desired or to clean out undesired and hazardous deadwood and restore a natural symmetry to the tree. Occasionally a branch will break but remain hung up in the tree; we’ll come remove it solely and safely.

Tree Removal

Removals are recommended for trees in decline and those severely damaged by wind, lightning, or pests. (Please see our Tree Diseases page for explanations and images of common tree maladies in the area).

Another reason for removal may be for the aesthetic value of improving the particular use of your property. Of course a brush pile that needs to go is something else we can accommodate. A visit from a professional will help you determine the best course of action for your treescape.

Stump Grinding

We offer options for stump grinding after a tree has been removed, including hauling the chips away or leaving them in place for the property owner to use for landscaping purposes. There are limitations, though; some stumps are too close to objects that prevent any stump grinding for safe removal or damage to property.

At Korte’sTree Service, we will assess and discuss the most economical approach for the removal of the tree stump and make recommendations on the best course of action.
