What license age does and does not mean
A registration first issued decades ago means the credential has been maintained that long. It does not necessarily mean the same people run the business, or that the business has traded continuously. Ownership can change while a registration is kept alive. Read it as a fact about the license, not a citation for the firm. Method is on the sources page.

Licensed for decades. Put it on the website.
A registration held this long is a fact homeowners trust. The site puts the year, the license number, and the finished work where they look before they call.
