CWS Construction in Berkeley, CA | Rowan Construction Group Oakland
We provide independent CWS cabinet and construction service across Berkeley, not as an authorized dealer but as experienced local installers who know how these boxes behave in fog-belt moisture and seismic micro-movement. The one thing that makes our CWS work here different is that we’ve spent years sequencing cabinet installs around Berkeley’s Alquist-Priolo geologic reviews in the hills and anchoring to shallow perimeter foundations in the flatlands. Call (628) 300-4376 to schedule your free estimate.
Why Berkeley Residents Choose Us for CWS Service
We’ve worked on CWS cabinetry and trim packages in Berkeley’s pre-1935 housing stock since 2007. That’s nearly two decades of watching particleboard toe kicks swell in the marine layer near the bay and cam-lock joints work loose in the constant tremor of the Hayward Fault zone. CWS sales & service is what we do, but we don’t pretend to be the factory. We’re independent technicians who source CWS-compatible OEM hardware and quality aftermarket soft-close slides, and we tell you straight when refacing beats replacement.
Grant Rowan, our owner, grew up in Beverly Hills and picked up his first framing hammer in a summer trade program at Santa Monica College before completing the full construction technology curriculum there. He’s spent the better part of twenty years running jobs across the East Bay, including extended work in the Fruitvale district, and he’s known among repeat clients for tight scopes: line-itemized estimates, material specs with brand and model noted, documented inspections at each phase. Under Clause 1 of The Haven Standard, the price is written before anyone starts. Under Clause 3, no change proceeds without a signed change order. That’s the discipline that has kept our projects within a few percent of the agreed number across 4,000-plus jobs.
We serve Berkeley service area homeowners who research contractors the way they research appliances, reading the three-star reviews and wanting the price range on the page before they make contact. We put the number in writing. Every time.
Common CWS Construction Problems We Solve in Berkeley

- Moisture-swollen cabinet boxes in flatlands homes. Particleboard and MDF CWS boxes wick up moisture where marine-layer fog sits heavy, especially near the bay. The toe kick and sink base delaminate first, right where the cabinet meets a shallow perimeter foundation that offers no moisture barrier. We see this regularly in west Berkeley Craftsman bungalows built between 1895 and 1935.
- Seismic-racked RTA joints in the hills. CWS Ready-to-Assemble cam-lock fasteners loosen under Berkeley’s constant seismic micro-movement. Doors rack out of square. Drawers bind. The Hayward Fault trace runs directly through hillside residential streets, and that vibration never stops, it just hums below perception.
- Thermofoil peeling on south- and west-facing runs. Hills homes rebuilt after the 1991 Tunnel Fire see hotter, drier summers than the flatlands. CWS laminate and thermofoil door skins bubble and peel on kitchen runs that take afternoon sun. Factory finishes weren’t spec’d for that thermal load.
- Vanity finish failure from moisture cycling. Berkeley bathrooms, especially in older Victorians with poor ventilation, cycle through hot showers and cold fog. CWS factory-applied vanity finishes crack and craze, exposing the substrate underneath. The damage is cosmetic until it isn’t.
- Foundation-anchoring failures on shallow perimeters. Original Berkeley flatlands foundations are perimeter-only, often brick or stone, with no central support. CWS base cabinets shimmed poorly on these uneven surfaces sag, separate from walls, or torque their face frames. Proper anchoring means knowing what’s underneath before the cabinet lands.

AfterCWS Service in Berkeley: What Local Conditions Mean for Your Equipment
Berkeley sits directly atop the Hayward Fault, and the Alquist-Priolo Earthquake Fault Zone trace cuts through hillside residential streets with a permit trigger: any construction within roughly 50 feet of the mapped fault requires a site-specific geologic hazard investigation before the city issues a building permit. This is not a formality. It’s a multi-week review that flatland jobs never see. For CWS cabinet or vanity installation in those hillside homes, the entire project sequence, from demolition to final anchor, has to be planned around that geotech timeline. Out-of-town installers bid these jobs like standard kitchen swaps and then stall, blaming the city. We build the review into our schedule from the first site visit. On a recent project near Grizzly Peak Boulevard, we had the geotech report in hand before the cabinets arrived, so the install proceeded on the day we promised. That’s the difference between a contractor who knows Berkeley and one who just has a Berkeley ZIP on their service map.
CWS Models & Products We Service in Berkeley

We work on the full CWS residential line: Ready-to-Assemble (RTA) cabinetry sold through building-material retailers, assembled base and wall cabinet lines, vanity and bath collections, and refacing doors and drawer fronts. For RTA units, we stock CWS-compatible OEM hinges, drawer slides, and shelf pins where the line is still supported. When OEM is discontinued or priced beyond reason, we match quality aftermarket soft-close hardware, Blum or equivalent, with the same mounting pattern so you’re not drilling new holes in a thirty-year-old face frame.
Our honest stance on repair versus replace: if the boxes are sound and only the doors, drawer fronts, and hardware have failed, refacing is the better spend. If the cabinet bottoms or sides are swelled, cracked, or out of square from seismic racking or moisture rot, replacement is the only fix that holds through a Berkeley wet season. We carry that assessment in writing, with photos, before you decide.

FAQs - CWS Construction in Berkeley
Yes, and we sequence the work around the required geologic hazard investigation, which we initiate before ordering materials. The permit delay is routine for us and typically adds two to four weeks. Call (628) 300-4376 to schedule a site visit and we’ll confirm whether your property falls inside the mapped zone.
Particleboard and MDF boxes wick moisture from marine-layer fog that sits heavy in west and central Berkeley, especially where the cabinet meets a shallow perimeter foundation with no moisture barrier. The toe kick and sink base go first. We replace with plywood boxes or full cabinets, seal the foundation interface, and upgrade to soft-close hardware. Call (628) 300-4376 for a free assessment.
Refacing is worth it when the boxes are square, dry, and structurally sound, which we verify with moisture meters and a level check. In Berkeley’s pre-1935 stock, we often find sound face frames with failed doors and drawer fronts from decades of use. If the substrate is swelled or the cam locks are stripped from seismic movement, replacement is the honest recommendation. We put both options in writing with prices before you decide.
Yes, with proper specification. Post-Tunnel Fire rebuilds in the Berkeley Hills mandate Class-A fire-resistant roofing and ember-resistant vents, and the interior environment runs hotter and drier than the flatlands. We specify thermofoil and laminate door skins rated for higher thermal exposure, and we avoid south-facing runs without adequate overhang protection. The cabinets themselves are sound; it’s the finish selection that has to match the microclimate.
We shim to level, anchor through the cabinet back to wall studs, and where the floor is uneven, we build a sub-base rather than forcing the box to twist. On shallow perimeter foundations, the floor often has settled differentially. We document the condition with photos, explain the shimming plan in the written scope, and install so the doors stay square through seasonal moisture swings. Measure twice, document everything, then build.
