How to Hire an Arborist
Two approaches to Tree Work
Tree work can be seen in two ways, a dangerous job that pays a decent return to an otherwise unskilled person with a strong back and a high tolerance for personal risk — or — a challenging profession for highly skilled, trained and experienced people with a healthy appreciation for the risks involved and a clear science-based and methodical strategy to minimize them.
Persons approaching the field from the former perspective come from all walks of life. There are plenty of outfits who offer employment to anyone, regardless of training, qualification, education or experience (or personal history). To be fair, many low cost outfits have personnel who bring many years of experience to the workplace. However, despite what the adage “practice makes perfect” might suggest, if you spend years doing something wrong, your final product doesn’t miraculously improve.
At the other end of the spectrum, the field of arboriculture offers certifications and accreditations which have their associated training and educational recertification requirements. There are professional standards, occupational safety standards, equipment maintenance schedules, and gear rating and replacement protocols. These outfits attract people who take their profession seriously and don’t rely upon luck and good intentions to keep bad things from happening.
The Basic Differences
Knowledge: When you hire an outfit from the lowest rung of the tree care spectrum, you may have retained one or two individuals with experience doing tree work. That experience may consist of on-the-job training, observation, and what has been passed on from the person's mentor including topping, wound paint, climbing spikes and cavity filling (practices that don't hold up to scientific testing). These are the guys in charge, and the staff of workers under them may be day laborers, relatives, basically anyone.
Crews from the upper end outfits should, at minimum, be staffed with Certified Arborists (certified through the International Society of Arboriculture) or Arborist trainees under a CA's supervision. This insures a minimum knowledge base. These men and women have been tested on tree identification, physiology, roping, rigging, equipment safety, aerial rescue, and professional conduct. They all must participate in training to keep their certification, and as a general rule, take pride in their profession. Knowledgeable tree care professionals can educate a client about the trees on their property. Proactive inspections can catch minor insect, soil and disease issues before they become major problems.
Quality: The quality of any work is a reflection of one's devotion to it. You will never meet anyone more devoted to the professional and safe treatment of trees than an ISA certified arborist. When a contractor under-bids a project, costs must be recouped somewhere. That is where corners are cut, staff are underpaid or unqualified, the job is hurried and poorly coordinated, and safety is compromised. Hasty work usually equates with sloppy work and sloppy results.
When a job is bid correctly, the equipment and manpower necessary to do the job are factored in, and the final result is something everyone can be proud of, both as a service provider and consumer.
Safety: Most of the reputable tree care service outfits I have worked around are safety obsessed. The Tree Care Industry Association (TCIA) offers certification in safety training, and is in the forefront of investigating tree worker accidents that lead to injury and fatality. This is not done out of morbid curiosity, but to create more stringent guidelines that will ultimately save lives.
Value: When it comes to pruning and live tree care, there is no comparison. Going with an unskilled operation will cost you in the loss of value caused by damage to your trees. Investing in the early nurturing of trees ultimately saves countless dollars and heartaches. Preventative maintenance saves property owners the investment that must be made to replace trees lost in their prime. Caring for trees is a supreme responsibility, which, if taken seriously, leads to well-informed staff making knowledge-based decisions.
If you hire an inexpensive tree crew to do work on your property, the intention is to save money. You may save money in the short term, but it may end up costing you in the hassle of house and lawn repair, damaged infrastructure like fences or pavement, or damage to surviving landscape and trees.
You may think you are supporting an honest working guy, but in reality you may be supporting unsafe and unprofessional operations at the expense of those companies who do higher quality work and treat their workers fairly. If the savings that is passed along to you comes from running an unsafe operation with unskilled staff, is that what you want?
Finally, you may intend to hire a sound and reputable company and find out that they are not what they seem. Ask for certification or at least records of safety meetings or related training, and be sure to ask to see current insurance documentation. It is a fact that you can be sued if an uninsured tree worker hurts himself on your property, even if they tell you they are insured.
