I'm sure Phil will weigh in on this at any moment, but in the meantime here goes. If the license was issued to you as a sole owner/proprietor, then you can request that the license NUMBER be re-issued. If the license has been expired for more than five years, you need to re-apply and the new application will still require four years of experience within the last ten years. You will also have to take both the law and trade exams.
