CGI cabinet installation here runs $4,000 – $13,000, countertops $2,000 – $6,500, and a full kitchen remodel $14,000 – $45,000. Call (803) 680-2547 for a written estimate before any work starts.
Why Rancho Cucamonga Residents Choose Us for CGI Service

We know the CGI catalog from the inside out because we build with it, not because there’s a badge on our truck. We’re independent of CGI and not authorized or endorsed by them. What we are is a crew that has installed CGI Ready-to-Assemble Shaker boxes, semi-custom raised-panel doors, and quartz slabs across Rancho Cucamonga long enough to know exactly where these products fail in this climate and how to stop that from happening. You can also read more about our broader CGI sales & service work across the region.
Isaac Pruett, our owner, grew up around finish carpentry and spent two decades remodeling homes across Los Angeles before bringing that standard to the Inland Empire. The first thing he checks on every CGI job is the trim and door alignment. If the gaps aren’t even, it’s not done. Every crew member who arrives at your Rancho Cucamonga home is background-checked, identity-verified under the Threshold Standard, and introduced by name and photo before the visit.

Common CGI Construction Problems We Solve in Rancho Cucamonga
- Warped or delaminating CGI cabinet doors and drawer fronts. Dry inland heat pulls moisture out of wood fast. When CGI RTA boxes aren’t shimmed and backed correctly, doors twist and veneers separate. We re-align, re-shim, and replace damaged fronts before the problem spreads.
- Cracked CGI quartz slabs at sink cutouts and unsupported overhangs. We see this a lot on DIY installs where no plywood subtop was placed under the quartz. The stone flexes, then cracks. A proper subtop solves it permanently.
- Failed soft-close hinges and drawer slides. Family kitchens in Rancho Cucamonga put daily wear on CGI hardware. After a few years, slammed doors and heavy drawers kill the dampers. We replace with OEM CGI parts when available, or a spec-matched aftermarket equivalent when the factory part is backordered.
- Debonding backsplash and vertical quartz panels. In older Rancho Cucamonga homes, CGI panels get set over painted or dusty drywall without a scratch coat. The bond fails. We strip, prep, and re-set so the stone actually stays on the wall.
- Swollen cabinet boxes from years of high-desert temperature swings. Original 1990s and early-2000s boxes in Rancho Cucamonga have often absorbed and lost moisture so many times the doors won’t close square. We rebuild or replace with fresh CGI lines that can handle the climate.
CGI Service in Rancho Cucamonga: What Local Conditions Mean for Your Equipment
Here’s the thing generic CGI pages won’t tell you. Rancho Cucamonga sits in a high-desert wind corridor where summer humidity routinely drops into single digits. That dry heat pulls moisture out of wood cabinetry and dries the resins in CGI quartz. What works fine in a coastal LA install can crack and gap out here if the tolerances are wrong. In neighborhoods like Alta Loma and Etiwanda, where homes sit closer to the foothills and catch stronger canyon wind, we install with tighter expansion gaps and use more durable seam work than we’d spec for a beach-adjacent kitchen. That’s not a preference. It’s the difference between a countertop that lasts and one that develops a hairline crack two summers in. Nobody else in Rancho Cucamonga is writing this down in one place.
CGI Models & Products We Service in Rancho Cucamonga
We service the full CGI line relevant to Rancho Cucamonga kitchens and baths: the Ready-to-Assemble (RTA) Shaker cabinetry, the Semi-Custom Shaker and Raised-Panel cabinet lines, CGI Quartz and marble-look slab countertops, and CGI Maple and Birch solid-wood cabinet doors. When a hinge or slide fails, we use OEM CGI hardware and touch-up kits where they’re available so the finish and alignment match factory spec. Where a CGI-specific part is backordered, we install a high-quality aftermarket hinge or slide that meets or exceeds the original specification, and we tell you which one you’re getting and why. We’ll also be straight with you when a box or slab is past saving and replacement is the smarter long-term call.

FAQs – CGI Construction in Rancho Cucamonga
Yes, when they’re installed with the right expansion tolerances. CGI maple and birch cabinet boxes do fine in inland dry heat if the installer shims every box, allows for wood movement, and doesn’t over-tighten fasteners. The failures we see in Rancho Cucamonga are almost always from rushed installs, not the product itself. Call (803) 680-2547 if you want an assessment of your existing cabinets before the next heat cycle.
Yes. We regularly pair CGI Quartz and marble-look slabs with CGI Shaker and raised-panel cabinet lines in the same Rancho Cucamonga kitchen. The factory finishes are designed to coordinate, and we order from matched samples so the undertones line up. Want to see slab and door together before you commit? Call (803) 680-2547 and we’ll bring samples to your home.
Most cabinet installation jobs run three to five working days once boxes are on site. Refacing adds a day or two. Full kitchen remodels with countertops and backsplash-like our Bathroom Remodeling in Rancho Cucamonga-typically land in the two-to-four-week range depending on slab fabrication lead times. Call (803) 680-2547 and we’ll give you a written schedule along with your estimate.
Small edge chips can usually be filled and matched. A crack running from a sink cutout or across a seam is structural, and in Rancho Cucamonga’s dry heat it will likely keep traveling. In those cases we recommend replacement with proper plywood subtop support. We evaluate every slab honestly before recommending repair or replacement. Call (803) 680-2547 to have a technician look at yours.
If the boxes are square, dry, and structurally sound, yes. We reface with new CGI doors, drawer fronts, and veneers. If the boxes have swollen or delaminated after years of inland heat, full replacement is the better call. We’ll show you the condition of your boxes before you spend a dollar on either path. Call (803) 680-2547 for a no-pressure evaluation.
