Raising

Removing the lower branches from a tree in order to provide clearance for buildings, vehicles, pedestrians, and vistas. Branches scratching against a roof or wall can cause extensive damage.
Thinning

The selective removal of branches to increase light penetration and air movement through the crown. Thinning reduces the likelihood of a tree blowing over in strong winds.
Reduction

Reducing the size/height of a tree. Compared to topping, reduction helps maintain the form and structural integrity of the tree.
Cleaning

The removal of dead, dying, diseased, crowded, weakly attached, and low-vigor branches from the crown of a tree.
Removal

Trees are removed down to a 2″ to 6″ stump.
