45 years experience and ready for the job ahead!

Cascade Building Company began as a small business 45 years ago in 1970 and has since incorporated as Cascade Building Inc. We are proud of our long list of satisfied customers and our reputation for quality work and integrity in the construction industry. With the USPS expected to stop mail delivery to 15,000,000 mailboxes over the next 10 years we see competition differently than most. Since there is going to be far more demand for cluster and wall mounted centralized mailboxes and replacements than the ability to meet the need, we see more of a cooperative and collaborative environment, as opposed to competitive environment to meet this challenge since demand will likely far exceed supply. We serve apartment and commercial building owner needs for USPS Post Office zip codes in the San Francisco Bay Area Counties of Alameda, Contra Costa, Marin, Santa Clara, Santa Cruz, San Mateo, San Francisco and Solano.
