The removal of storm-fallen boulevard trees often is the city's responsibility. |
Summer storms can ravage our urban forests requiring homeowners to remove broken limbs or downed trees. Or homeowners are scared into action when diseased or dead branches are hit by ferocious winds and they look out their window and think, "I hope that branch doesn't come down on top of the roof." Whether you're reacting or being proactive, here are tips on hiring an arborist.
When should you call in a professional?
First check with your city to see if the removal of any downed limbs or trees planted on public property, such as along street boulevards, city-owned property, or in public right of ways, is the city's responsibility.
An arborist will use a checklist to help diagnose a tree's health and vitality, and determine how hazardous it is. Immediate removal may or may not be necessary. Conks or mushroom-like structures forming on or around the trunk is evidence rot is present. Visible holes in the trunk weakens the tree's structural integrity. Small 'D' shaped holes and sawdust around the base of the trunk is evidence a pest is inside the tree, and may be damaging its vascular system. The arborist can correctly diagnose which pest and outline a course of action.
It is also recommended to use a professional when removing or pruning mature limbs or trees. The sheer size and weight of mature tree trunks and limbs can be overwhelming for someone without experience. Close proximity to structures and other trees can make the job more difficult and dangerous too.
It is also important to use a professional periodically to maintain healthy and structurally sound trees. Correctly pruning trees improves light and air exposure and shapes the tree's canopy.
Tips When Hiring an Arborist
Ask to see their arborist's license and chemical application license. Some cities require tree companies to register with the city before they can operate within city boundaries. In order to register to do business in the city, the company has to show proof of insurance and applicable licenses. Check your city's website for this list.
Get copies of proof of liability, personal insurance, property damage insurance and worker's compensation. Don't stop there - call the insurance company to verify that the policy is current. If a limb damages a structure, or a worker is injured, and the company isn't properly insured, damages are your responsibility.
Look for membership to professional associations. It shows a commitment to professionalism and he/she is more likely to be current with industry practices.
Clearly define in a contract what the contractor will do and the associated fee(s). For example, will the contractor haul debris away? Will the stump and exposed roots be ground away?
Warning Signs of a Bad Professional
A good tree care professional won't use spikes on a living tree unless it's being removed. Be leery of door-knockers who show up after storms. Many of these folks are not professionals, and probably came from out-of-state, and are chasing the quick buck.
If an ash tree is being removed within a county that is under quarantine because emerald ash borer has been discovered there, inquire how or where the wood will be disposed of. Wood and waste from ash trees cannot be moved outside the quarantine area.
