Our Story

Our Story

With over 12 years in sales and production at a leading Bay Area home improvement company, Edio Delfino saw an opportunity to do better—focusing on siding alone to deliver top-tier quality at an affordable cost.

Built on Integrity & Experience

In 1997, he founded All Coast Builders, Inc. with a clear mission:

Deliver expert siding installation using James Hardie^™ products, backed by honesty, craftsmanship, and competitive pricing.

The Delfino family has a long legacy of entrepreneurship throughout Placerville, Napa, and Northern California, and Edio proudly continues that tradition with a second-generation Italian-American work ethic—hard-working, honest, and detail-driven.
