CWS Construction in Highland Park, CA | Rowan Construction Group Pasadena
We provide independent CWS cabinet, countertop, and shower installation and repair across Highland Park, with pricing written before any work begins. The one thing that makes our CWS work here different is that we build around Highland Park’s Historic Preservation Overlay Zone requirements and hillside foundation conditions from the first site visit, not after permits stall. Call (562) 203-4508 to schedule your free estimate.
Why Highland Park Residents Choose Us for CWS Service
We’ve been installing and retrofitting CWS cabinetry, countertops, and fixtures in Highland Park’s pre-1930 housing stock since 2007. Grant Rowan, our owner, grew up in East Los Angeles and learned framing, concrete, and finish work at Los Angeles Trade-Technical College before he ever pulled a permit. That background shows up in how we approach a CWS kitchen or bath project here: we measure the existing structure before we spec the product, because our Kitchen Remodeling in Highland Park on a settled cripple-wall foundation demands a different plan than the same job on a modern slab.
We are not affiliated with or authorized by CWS. We are an independent construction team that sources OEM CWS hardware and replacement components when they are available, and quality aftermarket parts for concealed hinges, drawer slides, and glass seals when they outperform the originals. Our CWS sales & service work is guided by the same discipline we apply across all seven trades: a written price before any work starts, a signed change order before any deviation, and a documented photo record on every visit. Under Clause 1 of the Haven Standard, the number you agree to is the number you pay, within a few percent, on every Highland Park job we’ve completed.
Our crews are background-checked and uniformed. A live person answers calls 24/7. And we offer a Free Second Opinion on any written estimate you bring us, line by line, at no charge.
Common CWS Construction Problems We Solve in Highland Park

- RTA cabinet joints loosening from seasonal humidity and unlevel floors. Highland Park’s pre-1930 Craftsman bungalows often have original wood floors that have settled unevenly over a century. CWS Ready-to-Assemble cabinet joints, which rely on precise cam-and-dowel connections, separate when the box rocks on an unlevel surface. We sister the framing, level the run, and reinstall with OEM hardware.
- Cabinet boxes wicking moisture on uninsulated exterior walls. Many Highland Park cottages were built without wall insulation, and the exterior sheathing behind kitchen cabinets is often original redwood or Douglas fir that breathes moisture seasonally. CWS cabinet boxes installed flush against these walls absorb that moisture and swell at the toe-kick or back panel. We install a vapor barrier and stand the boxes off the wall on composite shims.
- Quartz countertops cracking at seams from foundation settlement. The 1905-1930 cripple-wall foundations common in Highland Park’s California Craftsman stock settle differentially, especially on hillside lots. CWS quartz countertops, which are rigid and unforgiving, crack at the seam when the substrate shifts even a quarter-inch. We assess the foundation first, and if movement is ongoing, we recommend a repairable substrate strategy or a smaller slab format.
- Shower pans and enclosures leaking after hillside settling shifts the floor plane. Highland Park’s cut-and-fill lots in the Arroyo Seco watershed move during El Niño cycles. A CWS walk-in shower pan installed level on a slab that shifts two years later will hold water at the curb or stress the glass frame seals. We build in adjustability at the curb and specify flexible glass-to-wall seals on every hillside installation.
- HPOZ stop-work orders from non-historic material specs. Contractors who standard-spec smooth stucco, vinyl windows, or T1-11 siding on street-facing facades of contributing structures routinely get stop-work orders in Highland Park. Even a CWS bath remodel that touches an exterior wall can trigger this if the contractor pulls permits without HPOZ clearance first. We verify HPOZ status before we submit.

AfterCWS Service in Highland Park: What Local Conditions Mean for Your Equipment
Highland Park’s Historic Preservation Overlay Zone is one of the largest in Los Angeles, and it adds a permitting layer that contractors working just across the border in Glassell Park or El Sereno never encounter. For CWS owners, this means that even a modest Highland Park Bathroom Remodeling project that modifies an exterior wall, window opening, or roofline on a contributing structure must pass design review for historic compatibility before the City will issue a construction permit. The HPOZ design standards explicitly prohibit smooth stucco, vinyl windows, and T1-11 siding on street-facing facades. We’ve seen contractors pull standard permits and get stop-work orders two weeks into a CWS cabinet and countertop install because they didn’t account for this step. That review alone can add months to a project timeline. We build HPOZ clearance into our pre-bid checklist on every Highland Park job, and we spec materials that pass compatibility from the start. On interior-only work that stays within the existing envelope, we design to avoid triggering exterior review entirely, saving time and preserving the homeowner’s original siding and window schedule.
CWS Models & Products We Service in Highland Park

We work with the full CWS residential product line commonly found in Highland Park renovations: CWS Ready-to-Assemble kitchen cabinets, which we level and shim on original floors before the joints take stress; CWS Shaker-style solid wood cabinet doors and drawers, where we stock OEM hinges and source upgraded soft-close concealed hardware locally for faster turnaround; CWS granite and quartz countertop slabs, which we template with digital measurement and cut to accommodate the irregular walls common in 1920s bungalows; and CWS walk-in shower pans and glass enclosure systems, where we pay particular attention to curb height and frame flexibility on hillside lots. We keep a running inventory of CWS-compatible hardware and replacement components in our Pasadena warehouse, and we source aftermarket drawer slides and glass seals that outperform the originals when the application demands it. We will always tell you if a CWS cabinet or countertop is repairable versus when replacement is the better long-term investment, especially on Highland Park hillside lots where movement is ongoing.

FAQs - CWS Construction in Highland Park
Only if the work modifies a street-facing exterior wall, window, or roofline of a contributing structure. Pure interior cabinet and countertop replacement within the existing envelope typically does not trigger HPOZ review. We verify HPOZ status before quoting and design to avoid unnecessary review when possible. Call (562) 203-4508 and we will check your property’s status during the free estimate.
Yes, with proper substrate preparation. We assess cripple-wall settlement with a laser level before templating, and we specify repairable or floating substrates on lots with ongoing movement. In some cases we recommend smaller slab formats or strategic seam placement to accommodate future shift. Call (562) 203-4508 for a site-specific assessment - estimates are free.
We install a vapor barrier between the cabinet box and the exterior wall, stand the box off the wall on composite shims to allow air circulation, and spec CWS solid wood or plywood-core boxes rather than particleboard in high-moisture applications. If the existing box is swollen beyond repair, we replace with OEM-compatible CWS components and upgrade the concealed hardware. Call (562) 203-4508 for an exact quote - estimates are free.
Interior-only work runs 3-6 weeks depending on material lead times. If HPOZ exterior review is required, add 2-4 months for City design review and compatibility approval before construction permits issue. We build this timeline into our written scope so there are no surprises. Call (562) 203-4508 to schedule your free estimate and we will confirm your project’s specific timeline.
Not for the shower itself, but if the bathroom addition or extension requires new foundation work on a cut-and-fill or steep-slope parcel, the City of Los Angeles may require a geotechnical report and hillside grading review. We identify this trigger during our initial site visit and include any required reports in the written quote. Call (562) 203-4508 for a free estimate with the full scope spelled out.
