Sterling Credentials & Reputation
Altera Design & Remodeling Bathroom Remodel Alamo CA

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.


National Kitchen & Bath Association (NKBA)

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.

"My 1980s bathroom was poorly designed but functional until I developed a chronic medical condition. Not only was the bathroom no longer functional, it was downright dangerous. The team at Altera Design & Remodeling did a superb job of giving me a bathroom that was both functional and beautiful. During the design phase, they asked me questions that had not even occurred to me, and they performed extensive research to identify quality products that best suited my present and future needs. During construction, Altera Design’s staff and all of the subcontractors brought the design to life and performed all work to the highest standards of quality. I experienced none of the remodel horror stories that my friends told me I would. In fact, if every firm had Altera Design’s high standards and dedication to customer service, remodel horror stories would not exist. I love my new bathroom. Thank you, Altera Design & Remodeling!"
