Healthy trees receive regular attention from knowledgeable arborists. But how can you tell when you choose an arborist if they’re truly an expert? Pick an inexperienced arborist, and your trees could suffer. Fortunately, there are ways to distinguish the true tree gurus from mere amateurs. In the following paragraphs we discuss how homeowners can find and select skilled arborists. We highlight questions to ask when hiring a professional, suggest which credentials to look for, and offer general tips about referrals and online reviews.
Call an arborist both to benefit from his or her expertise, and to stay safe throughout tree care tasks. Many tasks associated tree and shrub maintenance can be done at ground height, without the need of a ladder. However, if you are unable to access taller branches without the use of a ladder, it is best to call a professional. Working at height requires specialized training and equipment and is risky for the average homeowner because of the large number of variables, such as power lines, chainsaw manipulation, other buildings, etc.
Hiring the wrong contractor can have grave consequences for the health of your trees. Let’s take a look at some of the questions you should be asking arborists before hiring them for a project.
Questions to Ask before you Choose an Arborist in Portland
- Can they provide up to date certification of insurance, as well as a copy of their work contract, or in Oregon, their
construction contractor number?
- Do they have recent references? A quality company should be more than willing to provide up-to-date references.
- Will they give you a detailed estimate? This should include information about how long the project will take, the kind of equipment that will be used, as well as information regarding accessing the trees safely.
- What about a professional appearance? You can ask if the company uses spikes (which damages trees), offers “topping” (also harmful to trees), and if personal protection equipment (PPE) is used by all members while on a job site. Finally, ask how the workers will clean up the fallen leaves and branches that are trimmed away.
Credentials. As in all established fields, quality arborists tend to obtain industry certifications. Ask potential arborist contractors if they employ a Certified Tree Care Safety Professional (CTSP). You can also look for endorsements from the International Society of Arboriculture (ISA), and the Tree Care Industry Association (TCIA). For work that needs to be done near the electrical wires, the contractor will need to be an Approved Line-Clearance Arborist.
General tips for Selecting a Certified Arborist
Beware of scammers. Unfortunately, there are plenty of people who pose as tree care professionals, but who are undertrained and/or underinsured. Here are some tips to help you identify true tree care professionals, and steer clear of those who would do a substandard job.
- ANSI A300. Quiz the people you talk to about ANSI A300 standards for tree trimming. See if they know about this.
- Beware the use of certain terms such as “topping,” “lion’s tails,” and “hat racking.” These are often indications of an inexperienced or undereducated tree trimmer.
- Be sure to ask for credentials, verification of insurance, customer recommendations, and a detailed work proposal. If any of these items are lacking, beware!
- If you see differences in bid prices, it might be because a company is underinsured, or is under-experienced in estimating how many cuts—and therefore how much time—it will take to prune correctly. (The correct answer is about 1000; it takes about 1,000 cuts to expertly prune a tree.)
- Ask about permitting required to remove most large trees. Portland has some stringent requirements about this, as well about which trees can be removed. Be careful to double check permitting requirements, especially if your contractor insists that no permit is needed.
Additional 12 Tips for How To Choose An Arborist According to The Arbor Day Foundation
- Do the research yourself – check your local search results or the phone directory (if you have one) – businesses with listings can indicate some degree of permanence. Ask friends and neighbors in the area who they used and if they would recommend their work.
- Beware of door knockers, especially after storms. Reputable companies usually don’t go door-to-door.
- Find out if the arborist is certified through a local program or the International Society of Arboriculture (ISA) – All of Urban Forest Pro’s arborists are ISA Certified! Check for licenses if required in your city.
- Ask for certificates of insurance, including liability and workman’s compensation coverage. Verify the policy’s current status with the insurance company.
- Request local references and assess the arborist’s experience and reputation. Don’t rely solely on online reviews – its very easy to manipulate or gain fake reviews to “appear legit.”
- Determine if the arborist is a member of reputable organizations.
- Avoid rushing into bargains or paying in full in advance.
- Get estimates from multiple arborists without expecting bid matching.
- Look for an arborist offering a wide range of services, like pruning, fertilizing, cabling/bracing, lightning protection, and pest control.
- A good arborist recommends tree topping only under specific circumstances, such as saving a damaged tree or for formal settings.
- A conscientious arborist avoids using climbing spikes on trees meant to remain in the landscape.
- Beware of arborists eager to remove a living tree; removal should be a last resort.
Your trees are valuable to you and to the urban landscape around you. Don’t take chances with unlicensed, underinsured operators who may not know what they are doing. Hire a professional arborist and rest assured that your trees will thrive under the meticulous care of those who have the know-how to do the job safely and correctly.
