Altitude Arborist is a Cut Above the Rest
Altitude Arborist is a top tree and plant care company in Thornton. We use eco-friendly methods and follow the safest practices as we work to provide exceptional tree care. Altitude Arborist always guarantees top treatment, personalized customer service, and comprehensive education. Our services include:
Stump Grinding

If a customer would like to see the entire tree removed including the stump we can accommodate that! We can grind any size stump. Generally stumps are ground 6-8 inches below the surrounding landscape grade. For many stumps, the grinding will remove a majority of the root ball and some of the lateral roots.

Tree Removal

We own a bucket truck with a 65 foot reach to aid us in the removal of trees where access is adequate. We have arborists on staff capable of hand climbing trees in more remote areas of the landscape where our bucket truck cannot be utilized and the tree is safe to climb and remove.
