CWS Construction in San Carlos, CA | Rowan Construction Group Redwood City
Rowan Construction Group Redwood City provides independent CWS service throughout San Carlos, specializing in cabinet installation, bathroom remodels, and walk-in shower conversions using CWS Ready-to-Assemble and bath product lines. The defining difference in our San Carlos work is how we account for the city’s high-seismic-hazard zone and hillside settlement patterns before installing a single CWS cabinet or shower pan.

Why San Carlos Residents Choose Us for CWS Service
We’ve worked on enough San Carlos homes to know that a CWS vanity installation on the flatlands east of El Camino Real is a different job than the same vanity in a hillside neighborhood above it. Grant Rowan trained in construction technology at Los Angeles Trade-Technical College before spending years on Bay Area job sites, and his crew has handled CWS product failures across the Peninsula since 2007. We don’t sell cabinets - we install them so they survive the conditions that caused the last set to fail.
Our CWS sales & service approach is independent, which means we specify CWS where the product fits the application and recommend alternatives where it doesn’t. We use OEM CWS hinges, slides, and glass seals when they’re available, but we’ll substitute Blum soft-close hardware or reinforced shower pans when the original design isn’t holding up to San Carlos’s moisture and settlement patterns. Every project starts with a written flat price and scope - Clause 1 of the Haven Standard - and no work proceeds without that documentation signed.
Our crew is background-checked and uniformed; a live person answers calls 24/7; and every visit produces a documented photo record included as standard. The 365-Day Done Right Promise applies to every CWS installation we complete in San Carlos.
Common CWS Construction Problems We Solve in San Carlos

- Moisture-wicked cabinet boxes. CWS particleboard-core kitchen cabinets under postwar sinks absorb slow leaks that the homeowner never notices until the melamine skin bubbles and separates. In San Carlos’s 1,000-1,400 square foot ranch homes, those original galvanized drains are often sixty-plus years old. We replace the compromised box with a moisture-resistant substrate and upgrade to soft-close hardware.
- Settlement-stressed shower door seals. CWS frameless glass hinges and magnetic seals loosen as hillside homes on cut-and-fill pads shift incrementally. The resulting leaks damage surrounding tile and subfloor framing before they’re visible. We diagnose the structural movement, stabilize the enclosure, and reinstall with flexible sealant systems that tolerate minor racking.
- Temperature-cycled cabinet door cracks. Factory-finish CWS doors on 1950s San Carlos ranch homes develop hairline fractures at stile-rail joints after a decade of Peninsula temperature swings and seasonal humidity shifts. We assess whether refacing with higher-grade materials outlasts replacement.
- Deflected acrylic shower pans. CWS Tritan and acrylic pans crack at the drain flange when older slab-on-grade or post-and-pier subfloors flex under load. This is routine in San Carlos bathrooms before any walk-in shower conversion. We sister the joists or pour a reinforced mud bed before setting the new pan.
- Seismic-unsafe mounting points. CWS cabinetry and enclosures in San Carlos’s high-seismic-hazard zone require blocking and anchoring beyond standard residential practice. County plan check enforces this through cripple-wall and soft-story retrofit requirements that many homeowners discover at their first pre-application meeting.

AfterCWS Service in San Carlos: What Local Conditions Mean for Your Equipment
San Carlos sits in San Mateo County’s high-seismic-hazard zone with the San Andreas Fault running through the Santa Cruz Mountains to the west. Any CWS bathroom remodel or kitchen remodel that moves walls or adds a second story triggers mandatory cripple-wall and soft-story retrofit under county plan check - a step that isn’t required in many neighboring cities and that directly affects how we anchor CWS cabinetry and shower enclosures. We’ve learned to factor this into our written scope and price from the start, because a homeowner who discovers the requirement mid-project is looking at an unplanned five-figure line item.
The hillside neighborhoods above El Camino Real compound this with cut-and-fill pads that settle unevenly through wet winters, racking door frames and tilting shower pans in ways that standard CWS installation instructions don’t address. In one job on the hillside, we completed our Kitchen Remodeling in San Carlos on a 1950s ranch where the original CWS vanity had swollen and separated from the wall because the pad shifted during a wet winter. We removed the failing cabinet, sistered the cripple walls to current seismic standards, then installed a new CWS vanity and frameless walk-in shower with a reinforced pan tied into the new subfloor. The homeowner got a watertight, level bathroom that won’t rack when the next storm season hits. Measure twice, document once, build it so it doesn’t come back.
CWS Models & Products We Service in San Carlos

We work with the full CWS residential line: Ready-to-Assemble kitchen cabinets in standard and custom dimensions; 36-inch and 48-inch bath vanities with integrated tops and undermount options; frameless shower doors and tempered glass enclosures with chrome, brushed nickel, and matte black hardware; and Tritan and acrylic shower pans in curbed and curbless configurations. Our San Carlos service area warehouse stocks common CWS hinge sets, drawer slides, and glass seals for same-visit repairs when possible. When OEM parts are discontinued or the failure traces to a design limitation, we substitute Blum soft-close hinges, heavier-gauge slides, or custom-cut glass with upgraded seal profiles. We don’t push replacement for cosmetic issues, but when a particleboard box is delaminated or a pan flange is cracked, we recommend replacement because the underlying San Carlos conditions - moisture and settlement - will defeat any patch.

FAQs - CWS Construction in San Carlos
Does San Carlos require a seismic retrofit when I remodel a bathroom with CWS fixtures?
Yes, if your project moves load-bearing walls, adds a second story, or otherwise alters the structural system. San Mateo County enforces cripple-wall and soft-story retrofit requirements in San Carlos’s high-seismic-hazard zone. We identify this requirement during our initial site visit and include it in your written scope and price. Call (650) 560-7228 to schedule an evaluation.
Can you replace just the CWS vanity cabinet without replacing the whole bathroom?
We can, provided the surrounding plumbing, electrical, and substrate are sound. We often perform single-vanity replacements in San Carlos’s postwar ranch homes where the original CWS unit has failed from moisture or settlement but the shower and flooring remain serviceable. The replacement includes updated blocking and anchoring to current seismic standards.
Why do CWS shower pans crack in San Carlos hillside homes?
Cut-and-fill pads settle unevenly through wet winters, causing subfloor deflection that concentrates stress at the pan’s drain flange. Older slab-on-grade and post-and-pier construction in San Carlos lacks the stiffness that CWS acrylic pans assume in new construction. We reinforce the subfloor or pour a mud bed before installing the replacement pan.
What’s the typical cost to install CWS cabinets in a San Carlos kitchen?
Cabinet installation in San Carlos typically runs $4,000-$13,000 depending on linear footage, whether we’re working with existing CWS boxes or full replacement, and whether seismic blocking is required. A small kitchen refresh with CWS RTA cabinets and new hardware sits at the lower end; a full reconfiguration with custom modifications and soft-close upgrades runs higher. Call (650) 560-7228 for a line-item quote - estimates are free.
Do you need a pre-application meeting with San Mateo County before a CWS kitchen or bath remodel in San Carlos?
We recommend it for any project involving additions, ADUs, or hillside lots with non-standard setbacks tied to slope. County plan check can flag FAR or setback issues that aren’t obvious from standard lot dimensions, and catching these early prevents redesign costs. We handle the pre-application meeting as part of our project management - it’s included in our written scope when applicable.
