Common Questions

Before starting a project, most homeowners have the same concerns — with straightforward answers.

How established is Golden State Builders Group as a contractor?

We bring decades of combined experience to every project, with deep roots in the Walnut Creek construction market and a long history of completed local work.

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

Permit management is included in our standard project process. We pull permits, schedule inspections, and manage all city correspondence on your behalf.

Do you handle small remodels or only large builds?

We work across a wide range of project scales — from targeted single-room remodels to full custom home builds and large commercial fit-outs. No project is too focused, and no build is too large for our team to manage.

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.

What kind of guarantee comes with a finished project?

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.
