Finally, it never hurts to do some asking around on your own. If word of mouth spreads fast, then tales of woe spread like wildfire. If a neighbor knows a friend of a friend who once had a tree limb arrive unexpectedly on the living room carpet, accompanied by a shower of glass, chances are you’ll hear about it. And if this accident was the result of a botched limbing job by a so-called tree service professional, chances are you’ll find out who was responsible. But anyone worth hiring benefits from word of mouth and will be glad to provide a list of phone numbers of local clients satisfied with services rendered. As when dealing with any professional who will be working around your home, don’t be afraid to ask for references.
