At GB Builders Inc., building is more than a profession—it’s a family tradition rooted in integrity, craftsmanship, and care. For over 22 years, they’ve had the privilege of serving homeowners throughout the South Bay of California, earning trust one project at a time through quality work and genuine relationships.

Founded by brothers Raul and Irving Guangorena, GB Builders Inc. reflects the values they live by every day. As lifelong builders, business partners, and devoted fathers, Raul and Irving understand that a home is more than a structure—it’s where families grow, gather, and create lasting memories. That understanding guides every decision we make, from the materials we choose to the way we communicate with our clients.

They specialize in remodeling, new construction, and exterior hardscape, bringing a thoughtful and detail-driven approach to each project. Whether we’re revitalizing an existing home, building something entirely new, or enhancing outdoor living spaces, our focus is always on long-term quality—not shortcuts or quick wins. We believe the best work speaks for itself, and our extensive portfolio of beautifully completed projects stands as a testament to that belief.

With our office located in Palos Verdes Estates, we primarily build throughout the Palos Verdes Peninsula, while also serving surrounding South Bay communities. Being locally based allows us to stay deeply connected to the community we serve and maintain a hands-on presence at every job site.
