Tree felling is really a hazardous occupation that should not be undertaken by simply anyone. There is the risk of having trees fall on you, or on the house you are attempting to take them off from the vicinity of and many other risks. For this reason, you should hire an insured tree feller to remove any trees which are causing you problems.
If you hire a person sitting on the street corner to do your tree felling, you run the risk of causing untold damages to you property and the individual as well. You would then be responsible for their medical expenses because they were injured by an event on your property. In the event that you had hired a completely insured tree feller you'll not have this kind of problem.
Fully insured fellers are included in their own insurance and you may not be held responsible for their injuries or damages to your property should things fail. These would be the responsibility of the insurance company backing the tree feller.
