I have a sissoo that was in dire need of trimming. A certified arborist named Jack diagnosed what needed to be done. He recommended the crown clearing and have the tree grow more stronger by strategic pruning. If you decide to use them then the fee that the arborist charged for his advice will be deducted from the final price. I called and they had a crew the next day without me being there. I talked with Irene and she made the process so easy, she's the best! Came home to find my tree looking marvelous and thanks to the crew for cleaning up! The positive reviews really helped me decide to use Chip off the old block, they're simply the best in the business!
