If you have a dead or diseased tree in your yard, you might be considering hiring a tree service to remove it. However, sometimes it’s hard to know who has experience and training in tree care, and who simply has access to a chain saw and calls him or herself a tree service specialist. There are a few simple ways to verify that the tree service company is legitimate. First, ask the company to provide you with proof that they are licensed and insured. You may also want to make sure they have a pesticide license, if applicable. The company should always have a current business license and worker’s compensation policy, since these can protect you if any injury occurs while on your property.
