How long has Golden State Builders Group been operating in Walnut Creek?

Our team has been serving clients in Walnut Creek and the surrounding East Bay cities for many years, accumulating a portfolio of hundreds of completed residential and commercial projects.

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.

How do you handle unexpected costs or changes mid-project?

We handle scope changes through a formal change order process — every modification is documented, priced, and approved by the client before it affects the budget or schedule.

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.
