I’m sure everyone understands that hiring a licensed contractor is the safest way to ensure quality workmanship per code and completion of the job, but do you understand why?  To become a licensed contractor in either Minnesota or Wisconsin, an individual must study information regarding building codes, energy codes, and business operations, then must pass a test that includes all three aspects.  The life of learning is not done just because a person earned a contractor’s license.  Continuing education is also a requirement to retain the license, which must include twelve hours every two years for Wisconsin and fourteen hours every two years for Minnesota.  Furthermore, if there are any issues regarding building codes or business ethics, the state issuing the license can be the judge, jury, and executioner.
