Is asking your contractor for a license enough and does he have the correct license?
The state of Arkansas requires all Contractors, most trades and remodelers to have a license. There are also licenses for remodelers and some specialties businesses. You can find the definitions of these on the Arkansas Contractors Licensing Board web site (http://aclb.arkansas.gov/Pages/default.aspx). Unfortunately there are some people out there who will mislead you about the type of license they have, or if they even have one.
