CWS Construction in Lafayette, CA | Rowan Construction Group Walnut Creek
Rowan Construction Group provides independent CWS sales and service across Lafayette’s hillside and flatland neighborhoods, with kitchen and bath work that accounts for the city’s Wildland-Urban Interface fire codes and clay-soil conditions from the start. The one thing that makes our CWS work here different: we won’t order a single Yorktowne cabinet or Roma shower pan until we’ve assessed whether your lot needs a geotechnical soils report, because Lafayette’s building department routinely requires one before permitting any work that touches grading, foundations, or retaining walls on clay-heavy hillside properties. Call (510) 686-6370 to schedule your free estimate.
Why Lafayette Residents Choose Us for CWS Service
We’ve been working in Lafayette since before the Happy Valley ranches started showing their age. Our crews know the difference between a cabinet box that’s warped from humidity and one that’s twisted because the slab beneath it shifted on montmorillonite clay. That distinction matters when you’re deciding whether to reface a CWS Yorktowne kitchen or start fresh.
Grant Rowan, our owner, learned to read structural drawings at Los Angeles Trade-Technical College before he could legally rent a truck. He’s spent two decades building across Contra Costa County, including gut renovations in Walnut Creek’s Saranap neighborhood, and the discipline stuck: every change order is written, every material spec is named, and homeowners get a plain-English summary before any crew shows up. We source OEM CWS components when warranty or finish matching demands it, but we’re not beholden to factory part numbers when a premium aftermarket hinge or shower valve performs better in Lafayette’s climate. Our technicians are background-checked and uniformed; a live person answers calls 24/7; and every visit produces a documented photo record, included as standard.
Under Clause 1 of the Haven Standard, the price is written before anyone starts. No exceptions. Measure twice, document once, then we build.
Common CWS Construction Problems We Solve in Lafayette

- Yorktowne cabinet boxes warp and doors delaminate when installed on Lafayette’s cut-and-fill hillside slabs that experience differential settlement. We see this most in 1960s-80s ranches in the Happy Valley area, where the original grading has compressed unevenly over sixty years. Our fix: sister the floor joists, level the subfloor, then reinstall or replace the boxes with proper shimming.
- CWS Roma tub-to-shower pans crack at the drain flange when the subfloor flexes from expansive montmorillonite clay swelling. Lafayette’s wet-dry seasonal swing - saturated soils in winter, desiccated in summer - creates this motion predictably. We assess the subfloor structure before setting any pan, and we specify composite or reinforced bases when the flex exceeds normal tolerance.
- CWS Stoneworks quartz countertops develop hairline cracks over unsupported spans after a home’s foundation shifts, especially on older hillside builds with failing retaining walls. The quartz itself is sound; the problem is inadequate cabinet support or slab movement beneath it. We map the cabinet run with a laser level and add support brackets before templating any stone.
- Cabinet hinges and drawer glides corrode prematurely when Diablo wind-driven embers and ash enter through undersized or unsealed vents. This is a Lafayette WUI-specific problem that flatland contractors rarely encounter. We replace vents with ember-resistant models as part of any kitchen or bath project in the hazard zone.
- Retrofit installations trigger permit delays when homeowners don’t know Lafayette requires a geotechnical soils report for work on hillside lots. We’ve seen six-month holds because the report wasn’t ordered upfront. We flag this in our first site visit and include the timeline in our written quote.

AfterCWS Service in Lafayette: What Local Conditions Mean for Your Equipment
Lafayette’s building department requires a geotechnical soils report for any CWS kitchen or bath permit that touches grading, foundations, or retaining walls on the city’s clay-heavy hillside lots - a step that adds two to four months and several thousand dollars before a single cabinet is ordered. This isn’t bureaucracy for its own sake. The montmorillonite clay beneath Lafayette’s post-BART development neighborhoods swells when saturated and shrinks when dry, exerting pressure on retaining walls, slabs, and the structures above them. A soils report identifies whether your lot needs engineered footings, drainage correction, or retaining wall repair before interior work proceeds. We’ve learned to sequence projects around this requirement: assess the site, order the report, remediate any structural issues, then template and order CWS product. Skip the sequence and you’re either permitting twice or living with cabinets that won’t close square in three years. The flatland homes near downtown Lafayette typically avoid this layer, but anything in the hills - Happy Valley, upper Reliez Valley Road, the slopes above Highway 24 - should budget for it.
CWS Models & Products We Service in Lafayette

We work with the full CWS residential line, with particular depth in the systems we install most often in Contra Costa County kitchens and baths:
- CWS Yorktown / Yorktowne cabinet lines - framed and frameless boxes, with door profiles from Shaker to raised panel. We stock premium aftermarket Blum hinges and Soft-Close drawer systems for faster turnaround on wear repairs, and we can match existing finishes for partial replacements.
- CWS Bath Chronicle vanity collections - single and double-bowl configurations. We typically pair these with Kohler or Toto fixtures, specified in the written quote with model numbers.
- CWS Roma series tub-to-shower conversion systems - including pans, wall surrounds, and glass enclosures. We carry reinforced subfloor materials and composite pan options for Lafayette’s clay-soil conditions.
- CWS Stoneworks quartz and granite countertops - templated and fabricated with sink and cooktop cutouts. We specify support brackets for spans over 24 inches, particularly on older homes with suspect slab conditions.
OEM CWS components are available for warranty claims and exact finish matching. For hardware and mechanical parts, we use aftermarket when it outperforms factory spec for local conditions.

FAQs - CWS Construction in Lafayette
Only if your property is on a hillside lot where the work touches grading, foundations, or retaining walls. Lafayette’s building department routinely requires a geotechnical soils report in these zones, which adds two to four months and several thousand dollars to the project. Flatland homes near downtown typically do not trigger this requirement. We’ll assess your lot on the first site visit and tell you before you commit. Call (510) 686-6370 to schedule - estimates are free.
Yes, in most cases. We source OEM CWS door and drawer fronts for exact finish matching, and we can often identify the original color code from an inside-edge sample. If the finish has been discontinued, we’ll show you the closest current match and document it in writing before ordering. Call (510) 686-6370 to schedule - estimates are free.
It depends on where and how it cracked. Hairline cracks at the drain flange from subfloor flex can sometimes be repaired with a reinforced overlay, but structural cracks or pan deformation usually mean replacement is the better long-term value. We assess the subfloor condition first - if clay-soil movement caused the crack, repairing the pan without addressing the flex just guarantees a repeat failure. We’ll show you the photos and give you both options in writing.
Yes. We routinely work in Lafayette’s Wildland-Urban Interface zones and specify ember-resistant vents as part of any kitchen or bath project where the existing venting is undersized or unsealed. This is written into the scope, not treated as an add-on. Our crews know the CBC Chapter 7A requirements and document compliance with photos for your permit file.
Expansive montmorillonite clay swells when wet and shrinks when dry, stressing slabs and the cabinets above them. We laser-level every cabinet run before templating and add support brackets for spans over 24 inches, particularly on older homes with differential settlement. If your slab has moved more than normal tolerance, we’ll flag it and recommend structural remediation before stone installation. Call (510) 686-6370 for an exact quote - estimates are free.
