How to select a tree service

The International Society of Arboriculture has listed tips for selecting a tree service or arborist. These tips can save money and help avoid hiring the wrong company. Read these carefully before hiring.

Check in the phone directory, usually under Trees, Tree Service, or Tree Care Service. Although anyone can list themselves in the yellow pages, a listing at least indicates some degree of permanence.

Beware of door-knockers. Most reputable companies have all the work they need without going door-to-door.

Never be rushed into bargains such as ³if you sign an agreement today, I can take ten percent off the price.² Never pay in advance. Ask for certificates of insurance, including proof of liability for personal and property damage, and worker¹s compensation. Then phone the insurance company to make certain the policy is current.

Ask for local references from other jobs the company has performed. Take a look at these and, if possible, talk with the former clients. Experience, education and a good reputation are signs of a qualified arborist.

Determine if the arborist is a member of organizations such as the American Forestry Association, American Society of Consulting Arborists, International Society of Consulting Arborists, International Society of Arboriculture, or the National Arborist Association. Membership does not guarantee quality, but lack of membership casts doubt on the person¹s professionalism.

Have more than one arborist look at the job and provide estimates.

Making an agreement

The terms of an agreement are usually made verbally. To prevent misunderstanding and be assured of the work agreed upon, get a written agreement. Most companies have their own form. Listed below are several key items that a written agreement or contract should include:

• Dates the work will begin and end.
• Exactly what work will be done. For example, prune all dead, dying, diseased and weak branches one and one-half inches or greater in diameter.
• Specify what cleanup will be done and when.
• The total dollar amount you will be charged.
