Check for ISA arborist certification. ISA Certified Arborists are experienced professionals who have passed an extensive examination covering all aspects of tree care. Miller’s Tree Service has three internationally certified arborists on staff.
Ask for proof of insurance. A reputable tree service carries personal and property damage insurance as well as workers’ compensation insurance. Miller’s Tree Service is fully insured with over one million dollars of general liability and worker’s compensation insurance.
Ask for references to find out where the company has done work similar to what you are requesting. Miller’s Tree Service is more than happy to provide a list of references and past customers for you to contact.
Don’t always accept the low bid. You should examine the credentials and the written specifications of the firms that submitted bids and determine the best combination of price, work to be done, skill and professionalism to protect your substantial investment.
Be wary of individuals who go door-to-door and offer bargains for performing tree work. Most reputable companies are too busy to solicit work in this manner.
Keep in mind that good arborists will perform only industry- accepted practices. For example, practices such as topping a tree, removing an excessive amount of live wood, using climbing spikes on trees that are not being removed and removing or disfiguring living trees without just cause are improper practices and violate industry standards.
