We are The Tree Pruning Experts. Our method consists of using a variety of pruning techniques to improve the safety, structure, and natural appearance of trees. Crown cleaning is a pruning technique that involves the selective removal of dead, diseased, and structurally weak branches. Crown thinning is the selective removal of branches to reduce crown density and to increase light penetration and air movement through the crown of the tree. Tree limbs that overhang the roof of a house and areas of high foot traffic such as driveways are often removed for safety and clearance.
