What Clients Ask Us Most

Clients often come to us with similar questions before getting started — so you read more know exactly what to expect.

How much experience does your team actually have?

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.

Who manages the permitting process on my project?

We handle all permit applications, city submittals, and required inspections as part of our project management service — clients don't need to navigate the permitting process on their own.

Is there a minimum or maximum project size you work with?

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.

How are change orders managed?

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.
