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 our generation.  We are happy to have  maintained the Aloha Spirit at Construction Materials.  No prompting here.  Only one niche, sure wish we could have put everything we sold online...lol 

Please call us Monday - Friday from 6:30am - 4:00pm.  We've also remembered to innovate for those after hour emergencies too.  So 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."
