Diamond Certified

Altera Design has consistently been rated one of the best kitchen and bath firms in the San Francisco Bay Area by the American Ratings Corporation, who has honored us their coveted Diamond Certified status every year since 2005. The American Ratings Corporation is known to provide the most accurate ratings of local companies available because of their rigorous 12-step process that uses independent analysis to measure a company’s performance in the areas of customer satisfaction, insurance coverage, license, business practices and complaint bureau status. In order to be Diamond Certified, companies must score greater than 90 on a 100 point scale of customer satisfaction and loyalty. Companies are tested initially and then on an ongoing quarterly basis to ensure consistently top service levels and adherence to strict Diamond Certified service guidelines. Only the “best of the best” rated the “Highest in Quality” earn this prestigious distinction.

Altera Design is a proud member of the National Kitchen & Bath Association (NKBA), a national trade association with more than 40,000 industry professionals who sets the gold standard for kitchen and bath training and certification.
