CGI Construction in Ontario, CA | Alder Contractors
CGI cabinet and countertop service in Ontario comes down to this: we’re an independent contractor who fixes and upgrades CGI kitchens and baths across the 91758, 91761, 91762, and 91764 ZIP codes, and the work here looks different because Ontario’s postwar tract homes throw aging plumbing and narrow lot lines at us on nearly every tear-out. We handle CGI cabinet installation, refacing, quartz and granite countertop programs, and full kitchen remodels with OEM-matched parts. Call (833) 467-7020 for a free estimate.
Our CGI work spans the whole range: Euro-style frameless full-overlay cabinets, shaker and raised-panel door styles, vanity and bath cabinetry lines, and quartz or granite tops. We’re not manufacturer-authorized, and we’ll be upfront about that. What we are is a crew that has pulled apart enough CGI installs in Ontario homes to know exactly how they fail here. If you’re weighing reface versus replace, we’ll give you a straight answer. Learn more about CGI sales & service.
Why Ontario Residents Choose Us for CGI Service
Nelson Ibarra grew up in the Willow Avenue corridor of Rialto and spent years learning construction trades at Chaffey College in Rancho Cucamonga before building Alder Contractors across the Inland Empire. That background matters when we walk into a 91762 tract home and find galvanized supply lines behind the wall where your new island is going. We’ve been working on Ontario’s older stucco homes and the newer east-side subdivisions long enough to know the difference between a cabinet carcass worth saving and one that’s done.
We match OEM CGI hinges, slides, and door fronts when the box is sound so the finish and fit stay consistent. When OEM parts are discontinued or priced higher than the cabinet itself is worth, we step to quality aftermarket hardware and tell you why. That’s the independent difference. No authorized channel pushing a warranty script, just a straight read on what your kitchen actually needs. We serve the full Ontario service area with that same approach.

Common CGI Construction Problems We Solve in Ontario
- Thermofoil and laminate door skins peeling at the edges. Ontario’s dry heat and intense UV through south- and west-facing kitchen windows ages thermofoil faster than coastal air ever would. We see delamination starting at the bottom corners of doors and drawer fronts, especially on cabinets installed in the 2000s. If the box is sound, we reface. If not, we replace and stop the cycle.
- Frameless Euro hardware loosening and sagging. Older CGI frameless installs used particleboard or MDF carcasses. Add a few years of heavy daily use plus any moisture from past dishwasher or sink leaks, and the hinge screws lose their bite. Doors start to drop, drawer slides bind. We re-anchor hardware properly or swap in new OEM-matched slides when the box is worth keeping.
- Painted and thermofoil finishes chalking or yellowing near heat sources. Cabinets next to ranges and dishwashers in Ontario’s hot kitchens break down faster. The finish blisters, chalks, or yellows within a few years. That’s not a cleaning problem, it’s a heat-and-dry-air problem. We replace affected doors and panels, then adjust clearances so the next set lasts longer.
- Countertop seam and backsplash caulk failures from Santa Ana dust. Ontario’s wind-driven dust works into caulk joints and seam lines, breaking the seal and letting moisture underneath. Quartz and granite edges chip on older CGI tops when a homeowner tries to reuse them during a remodel. We recut, reseam, and seal properly for this climate.
- Plumbing surprises behind the cabinet line. We open a wall for a CGI island or a new vanity run in the 91761 and 91762 corridors, and the original galvanized supply lines are right there, fifty-plus years old. In Ontario’s older tract homes, you plan for that before you cut into anything.
CGI Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario sits at the heart of the Inland Empire’s logistics boom, so construction here is dominated by warehouse and distribution-center work along the I-10 and 60 corridors, tilt-up concrete shells on open ground, slab-on-grade industrial builds. But a few blocks into the 91761, 91762, and 91764 tract streets, we’re working on narrow 1950s-era lots with aging utility laterals. That split changes how we approach every CGI kitchen and bath tear-out, including any Upland CGI service calls we handle. Before we touch a cabinet line or cut a countertop, we locate the old plumbing and gas runs, because in these older Ontario homes they are rarely where modern plans assume they’ll be. A warehouse crew pouring a slab off Milliken Avenue doesn’t deal with that. We do, every single week.
On a 1950s single-story stucco tract home off Euclid Avenue in the 91762 core, our crew pulled a tired CGI raised-panel kitchen where the thermofoil doors had peeled and the drawer slides sagged. We found the original galvanized supply lines behind the wall while opening for the island, rerouted them, and set new full-overlay shaker cabinets, a quartz island top, and a tile backsplash. The galley finally worked. That’s the Ontario-specific reality of CGI work: the cabinet is the visible part, but the bones behind it are fifty to seventy years old.
CGI Models & Products We Service in Ontario
We work across the CGI cabinet and countertop lines Ontario homeowners most often have: Euro-style frameless full-overlay cabinets, shaker and raised-panel painted and thermofoil door styles, quartz and granite countertop programs, and the vanity and bath cabinetry lines. When we repair, we match OEM hinges, slides, and door fronts so the finish and fit stay consistent. If a line is discontinued, we source quality aftermarket hardware that matches the existing bore pattern and overlay. We keep common CGI-compatible hardware and touch-up finishes on hand for fast turnarounds across Ontario and for anyone needing CGI service in Chino, which means fewer weeks with your kitchen torn apart.

FAQs – CGI Construction in Ontario
We’re converting a garage or adding an ADU in Ontario – can you carry CGI cabinetry into the new kitchen or bath? Yes. We install CGI cabinet lines in garage conversions and ADU kitchens and baths across Ontario through our General Contractor in Ontario, and we coordinate the plumbing rough-in, electrical, and finish work under one contract. Call (833) 467-7020 and we’ll walk the space with you before any walls open up.
Are you authorized by CGI? No. We’re an independent contractor serving Ontario, not manufacturer-authorized, sponsored, or warranty-endorsed by CGI. That independence means we recommend refacing when the boxes are sound and replacement when they aren’t, not whatever the warranty manual says.
Do you use OEM or aftermarket parts for CGI repairs? We match OEM CGI hinges, slides, and door or drawer fronts when the box is structurally sound, because the finish and fit stay consistent. If OEM parts are discontinued or cost more than the cabinet is worth, we step to quality aftermarket hardware and tell you before we order anything.
How long does CGI service take in Ontario? A cabinet reface or hardware repair on an existing CGI kitchen typically runs three to five working days. A full kitchen remodel with countertops, island, and plumbing reroutes runs four to eight weeks depending on scope and any surprises behind the walls.
How much does CGI cabinet refacing cost versus full replacement in Ontario? Refacing usually lands between $4,000 and $13,000 when the boxes are sound. Full replacement, especially with a quartz island and countertop work, runs $14,000 to $45,000 in Ontario. Call (833) 467-7020 for an exact quote, estimates are free and line-itemed.
