More often than not, someone who describes himself as a professional handyman will more than likely have his skills and specialties listed at least on his business card, if not everywhere he advertises. On top of have a concise list of what he can do, he also would more than likely have a web page (even a free page that his ISP sponsors; not necessarily an expensive professionally done site) that would act as his resume, and provide details on his experience.
He may also have photos of recent jobs he’s accomplished, quotes from happy customers, multiple contact methods, and perhaps even a professional email address (firstname.lastname@example.org for instance). Here is an example of one of our most popular contractors at Tulsa Roofing that we have remained in contact with over the years and have recommended to our clients for years. These are the sort of credentials you, as a buyer, should be keeping your eye out for and taking mental notes on who does and does not meet them.
It’s up to you, the buyer, to decide how professional someone really is. Fancy business cards and websites and even good references won’t guarantee that the person you choose is going to turn out to be the perfect choice. Having been around for as many years as we have, these sort of things to look out for have come more natural to us and does not take as much effort which is what our ultimate goal is for anyone reading this.
