Unlicensed companies, illegal workers and any other practice that places a legitimate business in a non-competitive posture is completely detrimental. It's impossible to compete with those companies that don't play by the same rules that the majority of us have to comply with. If your company has never lost a job to one of these companies don't say you don't or won't turn them in. The day you lose money will be your wake-up call. At least it should be. If a competing company has an advantage that is illegal you owe to yourself and your business to stop that advantage. I have done it and will do it again. As far as the original post goes. An off target application is a violation. If the homeowner or is property was damaged in anyway he has every right to seek recourse.
