Mutual Materials

Mutual Materials is the largest supplier of masonry and hardscape products in the Pacific Northwest. Across Mutual Materials, we are proud of what we do and are inspired to see our products chosen by architects, designers, builders, landscape professionals and residential homeowners to build communities and living areas.

As a local family owned and operated company with fifth-generation family leadership that has been in business for more than 120 years, Mutual Materials was founded in 1900 by Daniel Houlahan as Builders Brick Company.  Following the Great Seattle Fire of 1890, our brick literally rebuilt Seattle and can be seen in many historic buildings today. As our company grew and expanded with new product lines and new geographic locations, the company name changed to Mutual Materials in the 1960’s.

Our products continue to build beauty that lasts through community hospitals, schools, stadiums, businesses, family homes, public parks, and home landscaping. Mutual Materials employs over 400 people and operates manufacturing plants and retail branches throughout Washington, Oregon, Idaho, Montana, and British Columbia.
