Cambria Construction in Ontario, CA | Polaris Contractors
We’re Polaris Contractors, and we fabricate and install Cambria quartz across Ontario, CA. When you call us, you get an independent Cambria fabricator-installer, not a dealer showroom. That matters in Ontario because this city’s older ranch homes sit on soil that moves, and Cambria slabs need sequencing and support that accounts for it. If you’re planning a kitchen or bath remodel in Ontario, call (855) 473-6535 for a free estimate.
Why Ontario Residents Choose Us for Cambria Service
Cambria is a proprietary quartz, and we treat it that way. We’ve built hundreds of Cambria kitchens and baths across the Inland Empire, including Cambria repair in Montclair, so we know how Ella, Torquay, and Whitehall behave once they’re in a real home, not a showroom vignette. Rick Sondermann, our owner, learned construction at Saddleback College and spent three decades renovating homes before Polaris Contractors ever touched a slab, and that background shows in how we sequence countertop work around settling floors and racked cabinets. In Ontario, that matters more than most people realize. We guide you to the right Cambria tone for your home’s light and water, then we install it to hold flat for years. As an independent shop, we’re not tied to Cambria’s dealer network, so we troubleshoot what we install and stand behind the finished surface ourselves.

Common Cambria Construction Problems We Solve in Ontario
Cambria is durable quartz, but it isn’t indestructible, and Ontario’s particular conditions create predictable failure modes. Here’s what we see most often:
- Slab cracking at sink and cooktop cutouts. Older Ontario ranch homes, especially in the 91761 and 91762 ZIPs, have wood-frame cabinets that flex and settle through hot, dry summers. When a fabricator leaves unsupported spans at the cutouts, the slab telegraphs that movement and cracks. We template with full support built in.
- Edge chipping and seam failure on overhangs. Cabinet racking in homes that haven’t had shear-wall or foundation bolting work pushes seams apart and chips edges, particularly at dishwasher-adjacent seams. We shim and level base runs before a slab goes down.
- Etching and dulling around sinks and drink stations. Inland Empire hard water and the mineral load from citrus-grove-era soil mean Cambria’s factory polish dulls faster here than coastal homes. We re-hone affected fields to restore a consistent finish.
- Dye transfer and heat ghosting from Santa Ana sun. Unshaded west-facing kitchen windows bake light Cambria tones like Ella and Torquay for hours. That sun exposure yellows the surface and ghosts darker dyes into the quartz. We advise on placement and window treatments before you commit to a tone.
- Seams left high by previous fabricators. We regularly re-hone factory seams that were never flattened properly. A high seam catches light, collects grime, and eventually telegraphs a crack. We fix that before it becomes a replacement.
Cambria Service in Ontario: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Cambria page: a large share of 91764 homes sit on former citrus groves, and when we template a Cambria countertop after a tear-out, we regularly hit old irrigation lines and pockets of organic debris right under the subfloor and cabinets. That debris decomposes, the soil settles, and base cabinets drop unevenly. A quartz seam that was dead-flat on install day throws out of plane a few months later, and the sink cutout becomes a crack waiting to happen. Ontario inspectors also demand extra soil and drainage documentation on the ADUs and room additions driving most of the countertop work here, much like our Upland Cambria service, so our cabinet-and-slab sequencing has to account for a rebuild that literally moves underneath a Cambria top. On a 1962 ranch in the 91762 ZIP, we tore out a galley kitchen and found base cabinets sitting directly over an old citrus-grove irrigation line and a pocket of organic debris. The floor had settled unevenly. We re-leveled the base and shimmed the runs before installing a Cambria Ella island and perimeter tops with a mitered edge, then re-honed a factory seam the previous fabricator had left high. That homeowner got a dead-flat, level-true Cambria surface that shouldn’t telegraph a crack at the sink cutout the way the old laminate-and-quartz patch did. That’s what local knowledge buys you in Ontario.
Cambria Models & Products We Service in Ontario
We work with Cambria’s full residential line, but in Ontario we see certain tones over and over. Ella, the marble-look white, is the most common pick for 91761 and 91762 ranch kitchen remodels. Torquay, a soft gray-white, gets spec’d constantly in ADU and room-addition kitchens. Britannica and Brittanicca, the gold-veined series, show up in higher-end remodels where the homeowner wants warmth. And Whitehall, a warm off-white neutral, is a frequent choice for bath vanities. Because Cambria is proprietary quartz, we repair with color-matched aftermarket quartz epoxies and re-hone the affected field. Replacement slabs come from an authorized Cambria source only. We don’t substitute a lookalike and call it Cambria.

AfterCambria Service Pricing in Ontario
Pricing in Ontario depends on slab square footage, edge profile, and how much prep your cabinets need before installation. Here are our current ranges for the Cambria work homeowners ask us about most:
| Service | Price Range |
|---|---|
| Countertop Installation (Cambria quartz) | $2,000 – $6,500 |
| Kitchen Island Installation | $3,000 – $10,000 |
| Small Kitchen Remodel | $9,000 – $20,000 |
| Backsplash Installation | $800 – $2,500 |
What drives cost most in Ontario is what we find under the cabinets. If your base is racked or the floor has settled, prep work adds to the total. That prep is what prevents a cracked slab a year from now. Call (855) 473-6535 for a free estimate, and we’ll give you a written line-item quote before any work starts.

FAQs – Cambria Construction in Ontario
Cambria is non-porous and heat-tolerant up to normal kitchen temperatures, but direct Santa Ana sun through an unshaded west-facing window is a different animal. Lighter tones like Ella and Torquay can ghost and yellow over years of that exposure. We’ll help you place the slab and choose a tone that won’t fight the sun. Call (855) 473-6535 and we’ll walk your kitchen’s light before you pick a color.
Usually, yes. Re-piping means opening walls and moving supply lines, and the countertop has to come out anyway. That’s the moment to replace a tired Cambria surface, not after you’ve put the kitchen back together. We’ll coordinate the tear-out and re-install so you’re not paying twice for slab handling. Call (855) 473-6535 for an exact quote.
Ontario inspectors are aggressive about soil and drainage documentation on ADUs and additions, especially in the 91764 ZIP where old citrus grove irrigation lines run under homes. We’ll sequence your cabinet and slab work around whatever reports and corrections the city requires, just as we do with San Antonio Heights Cambria service, so you’re not waiting on a countertop while the ground underneath gets re-engineered. Call (855) 473-6535 and we’ll talk through what your project needs.
If the seam is high, gapped, or cosmetically chipped, we can often color-match with quality aftermarket quartz epoxy and re-hone the field. But if the slab is cracked through or the seam has failed structurally, we’ll recommend replacement. A cosmetic patch over a structural failure telegraphs through within a year, and you’ll pay twice. Call (855) 473-6535 and we’ll give you an honest read on what’s repairable.
It can be, if you’re strategic. A small kitchen means less slab square footage, so Cambria Ella or Torquay stays within the $2,000 – $6,500 countertop range. Pair it with a simple edge profile and a modest backsplash, and your total stays reasonable. If Cambria pushes past your budget, we’ll guide you to another quartz or solid surface that fits. Call (855) 473-6535 for a line-item estimate on your specific kitchen.
