In addition it is important to check all aspects of a contractor’s business qualifications and certifications.  This includes checking a contractor’s basic paperwork and affiliations.  This is a great way to confirm that a contractor does indeed carry the required licensing, bonding and insurance requirements set forth by the state he or she contracts in.  Most contractors are required to be licensed by the state and pass a variety of certification and testing requirements.  Having the technical expertise, required training and necessary certification can go a long way in ensuring that a client’s project comes out as intended.
