The state of Minnesota is joining a nationwide effort to crackdown on unlicensed contractors. Charlie Durenberger with the Minnesota Department of Labor and Industry says the issue is widespread.

“We don’t’ know whether these individuals or businesses have the qualifications and the experience and the knowledge and the understanding of how to operate a business and how to perform good construction in Minnesota.”

Durenberger says licensed contractors are required to take a state examine and carry insurance, all things that help insure quality work and protect consumers if something goes wrong.
