In North Dakota, licensed contractors must carry an active workers' compensation policy as well as general liability insurance. Request a current certificate of insurance for both general liability and workers' compensation before any work begins.

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.
