Contact Rowan Construction Group Walnut Creek - Free Construction Estimate in Walnut Creek
Call us at (510) 686-6370 to schedule your free construction estimate in Walnut Creek. When you reach us, a live coordinator will connect you with our local team. There’s no hard sell, no pressure to decide on the spot, and no fee for the assessment. We’ll find a time that works, and in most cases we can get to your Walnut Creek home within a few business days.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during our operating hours and takes down the basics: what you’re looking to build or remodel, your Walnut Creek address, and any timing concerns. You’ll get a sense right away whether we’re the right fit.
Step 2: We schedule an on-site assessment. Grant Rowan or a senior member of our Walnut Creek team walks the job with you. We measure, photograph, and note conditions that affect pricing: access, existing structure, soil grade, utility locations. This visit typically takes 30 to 60 minutes.
Step 3: You receive a written, line-item estimate. Within two business days, we deliver a fixed-scope quote with every material and labor line spelled out. The price you see is the price you pay, under Haven Standard Clause 1: no work proceeds until the change order is signed, which is how our projects finish within a few percent of the original number.
Step 4: We build to the documented scope. Once you approve, we pull permits, schedule crews, and execute. You get photo documentation at key milestones and a final walkthrough with written evidence of completion. The warranty goes into effect the day we leave.
Why Walnut Creek Homeowners Call Us First

- We’re local to the 680 corridor. Our Walnut Creek team lives and works here, so we know the specific conditions that affect construction in this market: clay-heavy soils in certain pockets, East Bay Municipal Utility District requirements, and the permit timelines at Walnut Creek’s Community Development Department. That local fluency saves time and prevents surprises.
- Every pro working under our name is required to hold the license and insurance California requires. We verify coverage before anyone steps on your property, and license numbers are available on request. It’s part of our H.A.V.E.N. values code: Verified crews, with documentation you can check.
- Our pricing is flat and fixed before we start. Under Haven Standard Clause 1, no work proceeds on a change until the change order is signed. We’ve delivered over 4,000 projects since 2007 under this rule, and it’s the reason our jobs finish within a few percent of the estimate. No hidden fees, no “while we’re in here” upsells.
- We leave evidence, not promises. Every job gets photo documentation of conditions found, work in progress, and final state. You receive a written warranty and a project closeout packet. That’s Haven Standard Clause 4 in action: Evidence on every job.
