Why Claremont Residents Choose Us for CGI Service
Brent Calloway grew up in Midway City and spent nearly three decades on job sites across Orange County before building Square One Builders around a simple idea: one contractor, every system. That background matters in Claremont, where a kitchen remodel involving CGI cabinets rarely stops at the cabinet boxes. The same project often needs plumbing rough-in, electrical work, drywall repair, and sometimes foundation retrofitting in the older homes around the Village and the Claremont Colleges. We manage that full scope under one contract, which means you’re not the one juggling an electrician, a plumber, and a cabinet installer who don’t talk to each other.
Our crews have installed and refaced CGI cabinetry in dozens of Claremont homes, spanning bungalows from the 1920s, Spanish Colonial Revival houses, and post-war ranches. We know which CGI lines hold finish in this dry heat and which hardware fails first in bathrooms without proper ventilation. That familiarity lets us give you an honest repair-versus-replace answer in the first visit, not after the fourth callback. We also offer CGI repair in Upland with the same expertise.
We’re proud to offer CGI sales & service as part of our full-scope remodeling work. And because we’re a licensed general contractor, not a cabinet-only shop, the same team that specs your cabinets also handles the countertops, backsplash, plumbing fixtures, and flooring.

Common CGI Construction Problems We Solve in Claremont
- Swollen cabinet boxes and delamination in kitchens with poor ventilation. Claremont’s hot, dry summers followed by occasional winter dampness are rough on cabinet boxes that were never sealed properly. We see the worst of it in 1950s ranch kitchens where range hoods recirculate instead of venting outside. The fix is usually replacement of the affected boxes, not a band-aid.
- Drawer glide failure and hinge sag in older CGI lines. This shows up most often in bathrooms without working exhaust fans. If you own a pre-1980 home in Claremont, there’s a good chance your bathroom cabinet hardware is tired. We source OEM CGI glides when they’re still produced, and high-quality aftermarket replacements when they’re not.
- Finish cracking and peeling on south- and west-facing cabinet faces. The afternoon sun in Claremont is unrelenting, especially in kitchens with unshaded windows along Indian Hill Boulevard or up near the foothills. Cabinet faces that catch that direct sun for years will fade and crack. The solution is refacing with heat-tolerant finishes, or replacement if the substrate is compromised.
- Door misalignment and warping in older homes. Mid-century homes in Claremont were often built to breathe, which means seasonal wood movement is real. CGI cabinets installed without accounting for that movement eventually develop doors that won’t close square. We correct hinges, adjust reveals, and when needed, replace warped doors entirely.
- Out-of-production CGI hardware with no direct replacement. We see this constantly in remodel work from the 1990s and early 2000s. If your glides or hinges are from a discontinued CGI line, we’ll find an aftermarket unit that meets or exceeds the original spec instead of telling you to gut the whole kitchen.
CGI Service in Claremont: What Local Conditions Mean for Your Equipment
Here’s what you won’t read on a generic construction site: Claremont’s protected heritage trees, especially the mature Coast Live Oaks in the Village and around the Colleges, directly shape how any kitchen or bathroom remodel proceeds. The city requires arborist reports and tree protection plans before excavation or grading that could disturb root zones. That means a “simple” cabinet replacement that becomes a plumbing rough-in can trigger a permitting step that most contractors in neighboring cities never encounter. We plan for it from the first site visit. If your CGI kitchen sits near a protected oak off College Avenue or in a historic district home, we know when the arborist needs to walk the property and how to sequence the work so you don’t lose weeks waiting on paperwork. That’s not standard practice in Corona or CGI in Montclair. It’s standard in Claremont, and it’s why we’ve built our process around it.
CGI Models & Products We Service in Claremont
We work across the full CGI cabinetry lineup: the Advantage Series, Euro Series, Signature Series, and the Value Series. Each line has its own hardware tolerances, finish chemistry, and door-weight characteristics, and we stock common soft-close glides, hinges, and shelf pins for fast Claremont turnaround. When a part is still in production, we order OEM. When a line is out of production, we move to aftermarket hardware that matches or beats the original spec, then test the drawer cycles before we leave. You get honest guidance on whether refacing makes sense or whether the boxes have lost their structural integrity. If the boxes are solid but the doors and hardware are tired, refacing is often the better spend. If there’s swelling, delamination, or water staining, we’ll tell you replacement is the smarter investment, and we’ll show you why with the cabinet door off and the damage in plain view.

FAQs – CGI Construction in Claremont
Yes, most kitchen remodels in Claremont that involve plumbing, electrical, or structural changes require a permit. If the work is near a protected Coast Live Oak or another heritage tree, the city will also require an arborist report and a tree protection plan before excavation. We handle that paperwork and coordinate with the city’s design review process. Call (877) 688-9930 and we’ll tell you whether your specific project triggers the tree requirement.
Yes, if the cabinet boxes are structurally sound. Refacing replaces doors, drawer fronts, and hardware while leaving the boxes in place. It makes sense when the boxes are dry and square but the finish or hardware has failed. If there’s swelling, delamination, or water damage, replacement is the better investment. We’ll show you the difference in person before you commit.
We service and install CGI’s Advantage Series, Euro Series, Signature Series, and Value Series. Older homes around the Colleges often have Signature Series cabinets from past remodels, while newer projects trend toward the Euro Series for its cleaner lines. We’ll match your existing line when that makes sense, or spec a different one if your needs have changed.
For homes near Claremont’s foothill canyons, we recommend non-combustible or ignition-resistant materials wherever building code allows, particularly for exterior-facing elements and venting. The cabinet work itself is less of a fire concern than the surrounding structure, but we’ll coordinate with your roofer, sider, and window installer to make sure the whole project meets wildland-urban interface code. Since we carry roofing, siding, and windows under one contract, you don’t have to chase down that answer from three different contractors.
In Claremont, bathroom vanity installation typically runs $800 to $3,000 depending on vanity size, plumbing changes, and whether the existing cabinet needs removal and disposal. Handy homes with older plumbing often cost more because the rough-in needs adjustment. Call (877) 688-9930 for an exact quote, and we’ll measure and price it for free.
