Here's an example for you to think about. Out here in Pittsburgh, one of our established competitors was doing a large restaurant for a while and then decided that they needed to upgrade a lot of the ductwork, access panels etc., to stay in compliance with fire codes. He sent them the report via certified mail and they refused the additional cost so he told them he was stopping the work. They eventually found some new guy to do it for them and a few months later the place burns down completely. Fire marshall determines it was the duct work and calls up our competitor who proves he no longer did the work so they go after the new guy. Over $3 million in damages, the place burnt to the ground. All on the new guy. I don't care who you are, if you are new you don't have over $3 million in liability coverage because the costs are too much to handle. So this guy has lost his home, assets, everything, because he took on somebody else's discarded business.
Find something easier to start your business with like sidewalks, siding or awnings. There are a lot easier ways to make your money in this business. I'm not saying there's anything wrong with vent hoods, there isn't and there's definitely a lot of money to be made in this area of the cleaning business. It's just a little more involved than most of the other services you could provide as a new pressure washing company.
