Frequently Asked Questions

Before starting a project, most homeowners have the same concerns — so you know exactly what to expect.

How established is Golden State Builders Group as a contractor?

Golden State Builders Group has built a strong, established presence in the Walnut Creek area through consistent, high-quality work delivered over many years of active operation.

Do you handle the permits, or is that the client's responsibility?

Our team manages permitting from application through final inspection, coordinating directly with the local building department so you don't have to.

What size projects does your team typically take on?

We don't have a strict minimum, and we regularly take on projects ranging from targeted interior upgrades to full ground-up construction. Every client gets the same level of attention regardless of project size.

What happens if the scope changes after construction starts?

Any change to the original scope is presented to the client in writing before work proceeds. We don't move forward on additions or changes without a signed change order that clearly documents the new scope and the cost impact.

Are there warranties on materials and labor?

We provide workmanship warranties on our labor and pass through applicable manufacturer warranties on products and materials. Everything is documented at project handoff so clients know exactly what is covered and for how long.
