There are several areas you should evaluate when selecting a professional, qualified tree service in Madison, WI. First, check their references, both online & social media as well as with family and friends. These sources will give you a good sense of qualified tree service contractor even before you pick up the phone. Second, ensure all estimates are performed in person and provided in writing. All professional tree service companies will need to evaluate the tree (s) to be removed and trimmed in order to give an accurate estimate. Third, get at least three estimates from qualified companies. This will ensure you have multiple opinions as to what it will take to do the job correctly. Also, ensure you compare the estimates evaluating the scope of their work. You don’t want to compare apples-to-oranges, so to speak. Fourth, during the estimate process, discuss the specifics of your project, such as tree access; safety of property structures and neighbors’ properties; clean-up; and any other unique aspects of your job.
