About Us

Welcome to Construction Materials!


Construction Materials began in 1969. The founders (Florence and Bob) incorporated Robert P. Freitas Ent., Inc. in 1971.  Bob a Graduate of Kaimuki High School and a Retired Master Sergeant from Hawaii’s National Guard is best known for his quick witted humor and hilarious jokes. His wife Florence, the companies best kept secret, is the one lady who managed to fill any position whenever necessary.  We love you Mom...

On August 5, 2016, the Corporation transferred to the next generation.  We are happy to have maintained the Aloha Spirit provided by Mom and Dad.  The website is our way of offering you 24/7 service and pick up or will call Monday through Friday 6;30 AM to 4:00 PM.  

After 50 years in business it's likely we still have what you need even if it's not on our website.  For emergency issues call (808) 285-7918 and please feel free to order online, e-mail or fax when necessary.  

The one on one relationship has always been key to our success: "We will keep the traditions of our Kupuna (Founders) by maintaining the ‘Mama and Papa’ store tradition and perpetuate new technologies to be first in service."
