Olsen Brothers Tree Surgery - Provide these Services


Olsen Brothers Tree Surgery - Tree Pruning Determine what type of pruning is necessary to maintain or improve the health, appearance and safety of your trees. These techniques include:

  • Eliminating branches that rub each other.
  • Removing limbs that interfere with wires, building facades, gutters, roofs, chimneys, windows or obstruct streets or sidewalks.
  • Removing dead or weak limbs that pose a hazard or may lead to decay.
  • Creating better structure to lessen wind resistance and reduce potential for storm damage.
  • Training young trees.
  • Removing limbs damaged by adverse weather conditions.
  • Thinning or removal of unnecessary branches.
  • Improving the shape or silhouette of the tree.


Although tree removal is a last resort, there are circumstances when it is necessary. An arborist can help decide whether or not a tree should be removed. Arborists have the skills and equipment to safely and efficiently remove trees. Removal is recommended when:

  • The tree is dead or dying.
  • The tree is considered irreparably hazardous.
  • The tree is causing an obstruction that is impossible to correct through pruning.
  • The tree is crowding and causing harm to other trees.
  • The tree is to be replaced by a more suitable specimen.
  • The tree should be removed to allow for new construction.

Emergency tree care:

Storms may cause limbs or entire trees to fail, often landing on homes, cars, other structures or other trees. The weight of storm-damaged trees is great and they can be very dangerous to remove or trim. An arborist can assist in performing the job in a safe manner, while reducing further risk of damage to your property.
