CGI Construction in Ontario, CA | Stallion Contractors
We provide independent CGI cabinetry and millwork installation, refacing, and repair across Ontario, California. What sets our CGI work here apart is simple: we schedule every kitchen tear-out around South Coast AQMD Rule 403, which means water trucks and soil stabilization on even small residential demos, a compliance step most cabinet crews miss entirely. If you’re dealing with peeling thermofoil doors, swollen cabinet boxes, or cabinets pulling off the wall in a 1950s-1970s Ontario tract home, call us at (855) 600-3192 for a free estimate. We are an independent contractor and are not authorized, sponsored, or endorsed by CGI.

Why Ontario Residents Choose Us for CGI Service
CGI cabinetry shows up all over Ontario: builder-grade thermofoil doors in mid-century tract homes along Euclid and Mountain Avenue, semi-custom shaker boxes in newer infill builds, vanity lines in bathrooms remodeled through the 1980s and 1990s. Our crew knows which CGI door styles, box constructions, and finish options hold up in Ontario’s heat and dry air, and which ones fail first — experience we’ve built through our Upland CGI service and surrounding Inland Empire work. We match OEM CGI doors, hinges, glides, and shelf clips where they’re still available, and we use quality aftermarket European hinges and full-extension slides when OEM pieces are discontinued. Ruben Montoya, the owner at Stallion Contractors, grew up in nearby Colton and has been on Inland Empire job sites for over two decades, so we know Ontario’s housing stock the way only a local contractor can. We’re one team that handles the cabinets, the countertops, and the island, start to finish.

Common CGI Construction Problems We Solve in Ontario
- Thermofoil peeling and delaminating at door edges. Ontario’s summer heat cycles can hit 100°F-plus, and the dry Santa Ana air works on thermofoil door faces until they lift and curl. We see it most on exterior-facing kitchen walls where afternoon sun bakes the cabinet run. Whole door replacement or refacing usually beats trying to re-glue peeled thermofoil.
- Swollen particleboard and MDF boxes from old plumbing leaks. Older Ontario tract homes still have aging galvanized supply lines and original dishwasher hookups. When a slow leak goes unnoticed behind a CGI sink base, the box core swells and crumbles. Once the box is compromised, we recommend replacement, not patching.
- Cabinets racking or pulling away from walls. 1950s-1970s Ontario framing often has drywall-only anchor points where original installers skipped studs. Wall cabinets sag, doors stop closing flush, and the whole run starts to rack. We re-anchor to studs or add blocking, then re-hang and shim level.
- Drawer glides and hinges wearing out on builder-grade CGI boxes. After years of daily use, original glides bind, doors drift open, and drawers stick. We replace worn hardware with full-extension slides and adjustable European hinges so doors close flush and drawers glide cleanly.
- CGI vanity and bath cabinetry showing moisture damage. Bathrooms in Ontario’s older housing stock were often built tight with no exhaust fan. Humidity settles into vanity boxes, swelling edges and warping drawer fronts. We swap out damaged vanities and set them plumb against old framing.
CGI Service in Ontario: What Local Conditions Mean for Your Equipment
Here’s the thing most out-of-area CGI cabinet crews — even those offering a CGI service in Chino just up the road — never learn until the job’s already underway: Ontario sits under the South Coast Air Quality Management District, and Rule 403 is not a suggestion. Any grading or demolition, including a residential kitchen tear-out, requires active dust suppression, water trucks on site and soil stabilizer before debris leaves the property. On a mid-century tract home off Euclid Avenue near the 91762 ZIP, we tore out a 1960s kitchen with original CGI thermofoil doors that had peeled along every edge and particleboard boxes swollen from an old dishwasher leak. While water trucks held down the dust per AQMD Rule 403, we set new CGI full-overlay shaker boxes, shimmed them plumb against the old framing, and finished with a quartz island and countertops. The homeowner got a kitchen that finally closes flush and cleans up in the dry summer heat. Skip the water truck and the AQMD inspector can shut your job down the same afternoon. We don’t put our customers through that.
CGI Models & Products We Service in Ontario
We install and service CGI’s Euro-style full-overlay slab and shaker cabinet lines, the thermofoil and laminate door styles common in builder-grade Ontario tract homes, CGI ready-to-assemble and semi-custom cabinet boxes, and CGI vanity and bath cabinetry lines. Our parts approach is straightforward: OEM CGI doors, hinges, glides, and shelf clips when they’re still available, quality aftermarket hardware when the OEM line is discontinued. We keep common hinge and glide sizes local for fast Ontario jobs, and we order doors and boxes to spec when a full replacement makes more sense than refacing. This CGI sales & service work is what we do regularly across the Inland Empire.

FAQs – CGI Construction in Ontario
Yes. Ontario is under South Coast AQMD Rule 403, which mandates dust control for grading and demolition on even small residential jobs, so water trucks or hand-applied soil stabilizer are required before demo debris moves off-site. We handle all of it as part of the job. Call (855) 600-3192 and we’ll include dust control in your estimate.
When the boxes are structurally sound, we can reface or re-hinge rather than tearing everything out. If the particleboard or MDF core has swollen from moisture, refacing won’t last and honest replacement costs less over time than repeated patches. We’ll look at the boxes and tell you which route makes sense.
Usually it’s worn builder-grade glides and hinges, or a cabinet run that’s racked because the original installer hit drywall instead of studs. We re-anchor to studs, shim level, and swap in full-extension slides and adjustable hinges so drawers and doors close flush. Call (855) 600-3192 for a free hardware and alignment check.
Ontario’s 1950s-1970s housing stock frequently has galvanized supply lines behind bathroom vanities, and they’re often corroded enough to leak the moment you disturb them. We inspect the lines before we set the new vanity, and if they need replacing, we handle it as part of the job, no separate plumber call on your side.
Yes, and we do it regularly. New Ontario infill and ADU construction moves fast, and the same Rule 403 dust rules apply to grading and demo there, which is a step most new-build cabinet crews skip. As our General Contractor in Ontario operation, we coordinate it all. We’re already on-site with dust control in place, and we install CGI boxes, countertops, and islands so everything is under one contract.
