Joseph Pupa Sr. began providing quality building materials to the community in 1938. He believed that employee values should be the focus for building his company's reputation. With the strength built on those values, he passed the torch to his son, Joseph Pupa, Jr. Now, three generations have grown up in the business, with Joseph Pupa III having led our company since 2000, keeping the values stronger than ever. As proof of our long-standing reputation of customer service and satisfaction, we've built a company of employees determined to earn and keep your business. In the unlikely event you ever should have a problem, rest assured we'll be around - we own our corporate buildings, equipment and trucks. We've outlasted the Great Depression and every recession since, turned down hundreds of inquiries and offers to sell to larger firms, take an earnest approach to business, and reinvest profits where they belong . . . back into our products, facilities and services
