Why Pomona Homeowners Choose Cambria Construction
Rowan Construction Group Pomona provides independent Cambria service in Pomona across the eastern San Gabriel Valley, including fabrication, installation, and repair of Cambria quartz surfaces. We are not affiliated with or authorized by Cambria Company LLC; we source Cambria slabs through our independent stone suppliers and fabricate them in-house for kitchens and bathrooms across Pomona. Our Cambria work is priced in writing before any slab is ordered, with line-item costs ranging from $800 for backsplash installation to $6,500 for full countertop fabrication and set.
Cambria holds a particular place in Pomona remodels because the brand’s domestic manufacturing and consistent lot coloring matter on older homes where matching existing finishes is non-negotiable, which is why homeowners seeking Montclair Cambria service often face similar challenges. In neighborhoods like Lincoln Park and the historic downtown core, where Craftsman bungalows and post-WWII cottages sit on clay soils that shift with the seasons, a countertop installation that doesn’t account for cabinet movement and thermal cycling will fail regardless of the brand’s reputation. We’ve learned that the hard way so our customers don’t have to. Call (626) 606-1081 to schedule your free estimate.
Why Trust Rowan Construction Group Pomona for Your Cambria Construction?
Grant Rowan and our crew have fabricated Cambria in Pomona since the material first gained traction here in the early 2010s. We know the difference between Britannica’s warm gray veining and Torquay’s fine cream particles not from a sample card but from cutting hundreds of slabs in our shop and seeing how each behaves under a diamond blade, how the epoxy fills at the seam, and how the edge profile holds up to five years of dishwashers slamming against the sink rail.
Our independence from Cambria’s dealer network is an advantage for Pomona homeowners, not a limitation. We’re not pushing inventory from a corporate warehouse. We source the specific Cambria design you want, template to your actual room dimensions, and cut the slab to fit your cabinet run rather than forcing a stock layout that leaves you with a seam in the wrong place. Under Clause 1 of The Haven Standard, the price is written before anyone starts - every time, on every trade. That written quote includes the slab cost, fabrication, templating, installation, and a 365-Day Done Right Promise backed by terms you can read, not a handshake.
Grant grew up in Los Angeles watching relatives patch, pour, and frame their way through weekend projects - a decent preview of a career, as it turned out. He trained at Los Angeles Trade-Technical College before the first callus hardened, and over the past several years he’s built a steady presence across Pomona, from residential work near the Fairplex corridor to commercial jobs closer to downtown. The kind of contractor neighbors refer by first name. Measure twice, then we can talk.
Common Cambria Construction Problems We Fix in Pomona

- Seam failure from thermal movement. Cambria expands and contracts with temperature swings, and in Pomona’s eastern San Gabriel Valley heat pocket - where summer temperatures hit 105-110°F - seams installed over dishwashers or ovens without a proper heat barrier will open within two to three years. The joint blades, moisture gets in, and the epoxy bond fails. We see this most often on Britannica and Berwyn installs where the original fabricator skipped the aluminum or cement-board barrier. Our fix: remove the failed run, add the barrier, and re-seam with color-matched 100% silicone that flexes.
- Edge chipping at sink cutouts and undermount corners. Cambria’s polished edge looks sharp when new, but a thin 1/4-inch profile with no eased or rounded corner becomes a stress concentrator. Drop a cast-iron skillet, bump the corner with a heavy pot, or just close the cabinet door into the overhang too many times, and you get a chip that exposes the resin matrix. We repair with a color-matched fill when possible, or replace the affected section with a proper 3/8-inch eased edge that can take contact.
- Dull or etched spots from acidic cleaners. Cambria is quartz, not granite, and the resin binder reacts with vinegar, lemon juice, and some bathroom spray cleaners. Homeowners in Pomona’s older homes - where hard water mineral buildup drives aggressive cleaning - often mistake these white spots for hard water stains and scrub harder, making it worse. The etch is in the surface resin, not the quartz itself. We can polish out light etching with diamond pads; deep etching requires slab replacement.
- Stress cracks from unsupported overhangs. Cambria Ella and Torquay are popular for kitchen islands, but a 12-inch overhang on two corbels spaced too far apart creates a lever arm that cracks from the front edge back toward the cabinets. In Pomona, where clay soil movement can shift cabinets seasonally, an already-marginal support gets worse. We add hidden steel support rails or proper cantilever brackets, level the cabinets, and replace the cracked section.
- Cracks from unlevel cabinets. Post-WWII Pomona cottages built in the 1940s-1960s often have slab or shallow pier foundations that settle unevenly. Set Cambria on cabinets that aren’t shimmed and screwed to level, and the slab carries structural load it was never designed for. The crack starts at a sink cutout or cooktop opening and radiates outward. We don’t just replace the top; we level the cabinets first, or the new slab cracks the same way.

AfterCambria Parts & Our Repair-vs-Replace Approach
We fabricate with Cambria slabs sourced through our Pomona-area stone suppliers, not from a big-box store remnant pile. Our shop runs quality diamond tooling at the correct RPM for quartz - too fast and you glaze the edge, too slow and you chip it. At wet areas, we use color-matched 100% silicone, not cheap epoxy that yellows and shrinks. Behind cooktops and dishwashers, we install heat barriers as standard, not as an upsell.
When a Cambria top fails, we template the damage and give an honest repair-vs-replace assessment. A seam crack behind the cooktop on an otherwise sound kitchen? We’ll replace that run, match the veining from the same lot if possible, and leave your perimeter tops intact. A full kitchen redo is not the honest answer if only one slab failed. The written quote breaks out each option so you can screenshot and compare. Call (626) 606-1081 for a free estimate.
Our Cambria Service Process - Step by Step

- 1
Diagnosis and templating. We measure your cabinets with digital templating tools and check for level, square, and structural soundness. In Pomona’s older homes, we often find cabinets that have settled with the foundation or walls that are out of plumb by an inch or more. We document everything with photos - included as standard, not an upgrade - and note any cabinet or drywall work needed before the slab goes on.
- 2
Slab selection and fabrication. You choose your Cambria design; we source it and verify the lot number for color consistency. In our shop, we cut to template, polish edges to your chosen profile (eased, bevel, or ogee), and cut sink and cooktop openings with CNC precision. Seams are laid out to hide in veining patterns where possible.
- 3
Installation and heat protection. We set the slab on a bed of silicone, shim to level, and install heat barriers at all appliance-adjacent locations. Seams are bonded with color-matched adhesive and vacuum-clamped for a tight, flush joint. Sink clips are stainless steel, not plastic, and we seal all wet-area edges with mold-resistant silicone.
- 4
Testing and documentation. We run water through the sink, check for level with a digital gauge, and photograph the completed installation from multiple angles. You receive a documented photo record of the work, a written warranty under our 365-Day Done Right Promise, and a care sheet specific to Cambria maintenance - including what cleaners to avoid.
Cambria Products We Service & Install in Pomona
We fabricate and install the full Cambria design collection, with particular experience on the four most requested in Pomona kitchens and bathrooms:
- Cambria Britannica - warm gray veining on white, our most-requested design for Pomona kitchen remodels
- Cambria Ella - marble-look with subtle veining, popular for bathroom vanities and full-height backsplashes
- Cambria Berwyn - soft neutral with fine movement, common in smaller kitchens and cabinet refacing jobs
- Cambria Torquay - cream and taupe with fine particles, frequently chosen for mid-century Pomona kitchen updates
We stock color-matched silicone and diamond polishing pads for all four designs locally, so repairs don’t wait on shipping. Same-lot backsplash matching is available when we have the original lot number or a remnant sample.
We Also Service These Brands

Our shop fabricates across fifty-plus vetted brands. For countertops, we regularly work with Silestone quartz and source KraftMaid cabinets, Kohler fixtures, and Toto baths on full Kitchen Remodeling services. Multi-brand capability means your written quote includes honest numbers for each component, not inflated single-source pricing.
FAQs - Cambria Construction Service in Pomona
Is Rowan Construction Group Pomona authorized by Cambria? No. We are an independent Cambria service provider, not affiliated with or authorized by Cambria Company LLC. We source Cambria slabs through our independent stone suppliers and fabricate them in our own shop. This independence allows us to source any Cambria design and cut it to your room’s dimensions rather than a dealer’s stock layout.
Can you install Cambria over my existing granite or tile countertops to save money? Generally, no. Cambria requires a flat, level, structurally sound substrate. Tile grout lines create voids that crack quartz; granite overhangs and built-up edges interfere with proper support. The honest savings come from keeping sound cabinets and replacing only the top, not from layering materials. Call (626) 606-1081 and we’ll assess what’s actually reusable.
Is Cambria a good choice for a Pomona kitchen that gets a lot of afternoon sun and heat? Cambria performs well in Pomona’s heat if installed correctly. The resin binder can soften slightly above 150°F, so we install heat barriers behind cooktops and avoid direct sun exposure on dark colors without window treatments. Seams in sun-facing runs need expansion accommodation. We’ve installed Britannica and Torquay in south-facing Cambria in San Dimas and Pomona kitchens that have held up for years with these precautions.
My Cambria has a dull white spot near the sink that will not wipe off - what is it? It’s almost certainly etching from an acidic cleaner or citrus exposure. The white spot is damaged resin binder, not a surface stain. Light etching can be polished out with diamond pads; deep etching requires slab replacement. Stop using vinegar or lemon-based cleaners - they’re mistakenly assumed safe on quartz. Call (626) 606-1081 and we’ll diagnose the depth.
Will you match a Cambria backsplash to a slab that was installed by another company? Yes, if we can identify the design and source from the same or a compatible lot. Cambria’s domestic manufacturing helps here - color consistency is tighter than many imports. Bring a sample or photos with good natural light, and we’ll verify availability before quoting. Same-lot matching is not guaranteed on older installs, but we’ll tell you honestly before you commit.
Do you need to remove my cabinets to install a Cambria island? Not if the cabinets are level, square, and structurally sound. We template over existing cabinetry, add hidden steel support for overhangs, and set the island top in place. If your cabinets have settled with Pomona’s clay soil movement, we may need to shim or re-anchor before the slab goes on. The written quote separates cabinet prep from slab costs so you know where the money goes.
