The Maricopa County Home Show does not guarantee the quality of work or service from the companies listed and we do not accept any liability, express or implied, from the use of its vendor’s products or services. To be a contractor in Arizona, an entity must be licensed. Before your hire a contractor for installation work, be sure to research the company and verify that their Arizona Registrar of Contractor’s License is active and in good standing by visiting ROC.AZ.Gov. Often if a contractor is unlicensed, they may use subcontractors to perform the installation work, be sure to verify the subcontractors license status before agreeing to any scope of work.
