Understanding Our Contractor Rating System

Our contractor rating system at National Builder Check is designed to help you make informed decisions by providing a comprehensive evaluation of each contractor. Our ratings are based on multiple criteria, including the number of violations, customer reviews, licensing and certifications, years in business, project completion rate, quality of work, customer service, insurance coverage, and subcontractor relationships. Each contractor is rated on a scale of one to five stars, with one star indicating significant issues and five stars representing excellence across all evaluated areas. This multi-faceted approach ensures that you receive a holistic view of each contractor’s reliability and performance.
