Hiring An Arborist
Are your arborists certified?
Certified Arborists have passed an examination to prove that they have a certain amount of tree care knowledge, education and experience. Arborists are certified by the International Society of Arboriculture (ISA). Even if a company is a member of ISA, you should ask whether an ISA-certified arborist would be present to perform or oversee all work. You may ask to see their certification card or ask for their certification number. The crew doing the work does might also have Certified Tree Workers with the ISA. You may check for certification at www.isa-arbor.org.
What are your qualifications in tree care? What are the qualifications of your crew?
Professional organizations foster a commitment to use best practices and provide their members with resources to keep up with newest standards and information. Check for membership with the International Society of Arboriculture (ISA), the Tree Care Industry Association (TCIA), or the American Society of Consulting Arborists (ASCA).
What is your CA Licensed Contractor number?
Any quote for work exceeding $500, including time and material, requires the company to be a licensed contractor. You can verify a contractor’s license by contacting the Contractors State License Board at telephone (800) 321-CSLB, or www.cslb.ca.gov.
Can you provide proof of insurance?
A reputable arborist carries personal and property damage insurance as well as workers compensation insurance. Call their insurance company to verify coverage of $300,000 to $1 million. If an uninsured worker you hire gets hurt or does damage to property, you could be held financially responsible.
Do I need to get any type of permit to work on this tree?
A permit is required for street tree planting, pruning, and removal in San Jose. A reputable tree care company will be familiar with permitting requirements and take the time to be in compliance.
