Sometimes a project doesn't go the way you expected, and you're not sure how to work with the builder to resolve the issue. There is a procedure that you should follow:

Contact Your Builder In Writing
If you are unhappy with work that is completed, or feel that work was not performed as agreed to in contract, you are required to contact your builder in writing to maintain full warranty coverage as provided by the state of Minnesota. This also gives you legal documentation of the concerns you have.
File a Complaint
If you are unable to resolve issues with your builder directly, you have the option to file a complaint with the Minnesota Department of Commerce. The Department will ask that you submit your complaint in writing with copies of any documentation you may have. Visit their website for further details.
