AfterMeet the Walnut Creek Team Behind Rowan Construction Group Walnut Creek
Our Walnut Creek crew shows up in uniform, works from a written scope, and leaves behind a photo record and a signed completion sheet. Every person on this page has been background-checked and trade-verified before they ever knocked on a door in Diablo Valley. What ties us together isn’t a slogan. It’s the discipline of doing what we said we’d do, at the price we wrote down, with the brands we specified.
Our People
Grant Rowan, Owner
I’ve been running job sites since 2007, and I still walk every Walnut Creek project before the quote goes out and after the final walkthrough. I started this company because I got tired of watching homeowners eat change orders they never agreed to. Under Clause 1 of the Haven Standard, the price is written before anyone starts. That’s non-negotiable, and I’ve fired a subcontractor over it. I live in Contra Costa County, my kids went to school here, and I know which neighborhoods have the old clay sewer lines and which ones have the post-1990 ABS. When I’m not on a site, I’m usually reviewing photo records from the day’s jobs or answering calls myself if the line’s busy. Dry sense of humor, zero tolerance for “good enough.”
Marcus T., Lead Technician - Roofing & Exterior Systems
Marcus has been stripping roofs and reading moisture meters for fourteen years, and he can tell you whether your Walnut Creek home’s sheathing is plywood or OSB without climbing the ladder. He’s GAF Master Elite certified and Owens Corning Preferred, which means the manufacturers trust him to install to their spec, not “close enough.” Marcus carries a moisture probe on every roof inspection and photographs the decking condition before a single shingle comes off. Off the job, he coaches youth basketball in Pleasant Hill and has strong opinions about the BART schedule.
Elena V., Senior Installer - Kitchen & Bath
Elena joined us in 2019 after eight years running trim and cabinet installs for a high-end builder in Marin. She specializes in KraftMaid and Wellborn cabinet systems, and she’s the person who catches that a wall is “plumb in spirit if not in practice” before the countertop template goes out. Elena holds a California C-6 Cabinet, Millwork and Finish Carpentry license and she’s trained on Cambria’s installation requirements for their 3cm slabs. She keeps a notebook of every kitchen she’s worked on in Walnut Creek, with sketches of the solutions she engineered for the weird corners and out-of-square soffits. Her detail work is why our cabinet warranty claims sit at zero.
Derek K., Service Coordinator
Derek answers the phone when you call (510) 686-6370, and he’s the one who makes sure your written quote has the right shingle color, the correct paver pattern number, and the fixture model you picked from the Kohler catalog. He’s been with Rowan since 2015 and knows our fifty-one vetted brands well enough to spot a discontinued SKU before it delays your job. Derek schedules the inspections, pulls the permit status, and follows up the day after every installation to confirm the photo record uploaded correctly. He grew up in Walnut Creek, still lives here, and can tell you which permitting office line moves fastest on Tuesday mornings.
Javier R., Apprentice - General Construction & ADU Framing
Javier’s in his third year with us, rotating through every trade before he picks his specialty. Right now he’s framing a 480-square-foot ADU in the Shadelands area and learning the Walnut Creek ADU setback requirements by heart. He’s OSHA-10 certified and completing his California B-General Building apprenticeship hours. Javier documents every stage of his work with the same photo protocol we use on million-dollar remodels, because under the Haven Standard, documentation isn’t seniority-based. He asks more questions than some veterans, which is exactly why we hired him. His current obsession is learning to read structural plans without squinting.
One Standard, Every Job
The Haven Standard travels with our crew, not from a headquarters. When Marcus strips a roof in Walnut Creek, he follows the same photo-documentation protocol our San Jose roofers use. When Elena installs cabinets here, she works from the same written scope template, the same change-order discipline, and the same 365-Day Done Right Promise that covers every Rowan project across California. The brands don’t change. The flat-price-before-work-starts rule doesn’t change. What changes is the local knowledge: which Walnut Creek neighborhoods have the expansive clay soils that crack paver beds, where the city requires ADU fire sprinklers, how the summer inland heat affects vinyl window expansion gaps. That local intelligence lives in this crew. The standard lives in the system. You get both.
Every person on this page has been verified, uniformed, and trained on the documentation tools you’ll see on your job. The photo record, the signed change order, the written warranty - these aren’t department functions. They’re individual responsibilities, tracked by name. If something’s not done right, we make it right. The promise is printed on every page, and it’s backed by a terms page, not an asterisk.
Call (510) 686-6370 to schedule your free estimate. You’ll speak to Derek or Grant, and you’ll get a written price before any work starts. Always.
