By its very nature, tree work is dangerous and should only be done by a professional. Liability insurance is important because it protects you, the homeowner, and your property from potential risk and damage. Workman’s compensation insurance protects tree professionals while they are working on a job. When you are seeking to hire a tree company, be sure to request proof of comprehensive insurance from their insurance carrier before any work is started. If you have any doubts, call the insurance carrier for verification.
