References
Two checks, one done for you and one you have to do yourself.
Before signing a contract, verify the contractor's license status and complaint history through your state's official licensing board lookup, then call two or three references from projects of similar size and scope. A clean license record confirms the contractor's legal standing to do the work. Talking to past clients tells you what working with this contractor is actually like.
Start with the official record
State contractor licensing boards exist to protect consumers, and checking a contractor's license status takes a few minutes before you spend an hour on the phone.
"Protects consumers by regulating the construction industry through policies that promote the health, safety, and general welfare of the public in matters relating to construction, including home improvement."

California's board offers a free online tool to check a license and see complaint disclosure, and Florida's Department of Business and Professional Regulation offers a comparable public license and complaint lookup. Every state licenses and discloses this information differently; find your own state's licensing board and confirm what it publishes.
Call past clients yourself
The license lookup tells you the contractor is legally allowed to work. It does not tell you whether the crew showed up on time, answered the phone, or handled a change order without a fight. That's a phone call, not a database.
Ask each reference about a project close in size and scope to yours: did the price hold, did the schedule hold, and how did the contractor handle problems that came up mid job. This is common board practice, not a formal standard, so treat it as due diligence rather than a checklist owed to any authority.
Weigh what you hear, don't let one flag decide
A single closed complaint or one lukewarm reference is not automatically disqualifying. It's one more input alongside the license record, the bid itself, and anything you learn in a contractor interview. Boards are not required to hire the cheapest bidder, and the same judgment applies here: weigh the full picture before deciding.
Check yourself
Answer before you read the explanation, recalling it is what makes it stick.
A contractor's proposal looks solid and the price is the lowest of three bids. What should the board still do before signing?
A state license lookup shows a contractor has one closed complaint from three years ago. What does that finding mean for the board?
A past client tells the board the contractor finished on schedule but rarely returned calls during the project. How should the board use that information?

License lookup tools and what complaint records they disclose vary by state. Check your own state's contractor licensing board for what it publishes and how a complaint on file should factor into a bid you're considering.
