Family-Owned with Over 30 Years of Experience

Castañeda Iron Works about header sign

Welcome to Castañeda Iron Works, where iron craftsmanship meets family legacy. Our journey began in 1989 when my father, Pedro Castañeda, ignited the spark of this business. With over 30 years of experience, we have become a testament to dedication and skilled artistry. Growing up around metal and the glow of molten iron, I learned the art of welding at the age of 13. Our family-owned venture is not just a business; it's a tapestry of generations, woven together by a passion for iron works and structural custom designs brought to life. Today, we stand ready to bring that personal touch to your projects. We take pride in delivering exceptional work to our valued clients in the Bay Area.

  • Finding it virtually impossible to get a really small welding job done commercially in Marin County, I found Castaneda Iron Works in Richmond. The guy couldn't have been nicer or more helpful...I pulled in to his driveway and he came out to greet me, said he remembered our conversation on the phone and took my job into the shop on the spot and I was out of there in less than 10 minutes and he charged me a very fair price too.

    You don't need this service every day but when you do, it's nice to know that there's a good guy ready to help out at the right price.
