The company should provide a license, proof of insurance and state certification for you to consider hiring them. Insurance is important because it protects you from liability if a worker is injured at your home. You can use the company’s license to look up their work history through the Secretary of State's Office and Better Business Bureau. Call to verify if the company's license and insurance are current. Affiliations with the National Kitchen & Bath Association (NKBA), the National Association of the Remodeling Industry (NARI), and the Florida Home Builder’s Association (FHBA) are bonuses.
