Virginia law requires all contractors to include their license number on all documents to include contracts, proposals, bid forms, and advertising. It would always be prudent to ask to see a copy of the license before signing any contract. Once you have the number, you can confirm the license by calling the State Board for Contractors at 804-367-8511 or online at the Department of Professional and Occupational Regulation license lookup website.
