CGI Construction in Ontario, CA | San Bruno Construction
CGI cabinet and countertop service in Ontario usually means repairing or replacing RTA boxes, door skins, and laminate surfaces that inland heat and older tract-home conditions have worked over. San Bruno Construction provides independent CGI service across Ontario’s 91758, 91761, 91762, and 91764 ZIP codes and San Antonio Heights CGI service, and the thing that sets our work apart here is how we read the older framing, slab movement, and buried agricultural remnants under these kitchens before we ever set a new cabinet run. We quote repairs and replacements on what the product actually needs, not what a warranty flowchart says. Call (866) 472-1908 for a free estimate.
Why Ontario Residents Choose Us for CGI Service
Our crews open up CGI cabinetry every week in Ontario’s post-war tract homes and downtown remodels. That regularity matters because CGI’s RTA construction behaves differently in inland heat than it does a mile from the coast. Thermofoil peels along bottom rails. Sink bases swell. Uppers rack out of square on slabs that never stopped moving. We know these failure patterns before we unscrew the first hinge.
Noel Carvalho runs our Ontario jobs with an eye for what the house itself is doing underneath the cabinet line. He trained in construction technology at Skyline College, reading plans and load paths before any tool leaves the truck, and he has spent the years since applying that to real renovations. Good construction doesn’t announce itself – it just works, year after year. That standard shapes how we quote CGI repairs here.
We are an independent provider. Not authorized, sponsored, or warranty-endorsed by CGI. That independence means we recommend OEM doors and drawer fronts when a single run needs to blend, and we say so plainly when a whole run of particleboard has gone too far and replacement is the honest call. For homeowners in Ontario, that matters more than a badge on a website.

Common CGI Construction Problems We Solve in Ontario
Here are the specific failures we see most often in Ontario kitchens, tied to the conditions that cause them here:
- Thermofoil and laminate door skins peeling along bottom rails. The dishwasher kicks heat and steam at the cabinet face, and Ontario’s dry summers make the adhesive brittle faster than coastal air would. Homeowners near the 60 freeway see this on cabinets on south- and west-facing kitchen walls, where sun loads through older single-pane windows and Santa Ana winds drive dust into the seams. We replace door skins and drawer fronts with OEM CGI panels when the rest of the run is sound.
- Particleboard and MDF box panels swelling at toe kicks and sink bases. Slow supply-line leaks and winter rain intrusion go unnoticed behind cabinet doors, and by the time the finish blisters, the panel has often absorbed enough moisture to crumble. This shows up hard in 1960s and 70s tract kitchens with original plumbing. The fix is a plywood sink base and a new toe kick, not a patch over wet particleboard.
- RTA cam-lock and dowel joints racking loose, leaving uppers out of square. Ontario sits on expansive soils with a high water table from its agricultural past. Slab-on-grade floors shift seasonally, and that movement telegraphs into cabinet boxes. Doors drag, reveals go uneven, and corners pull open. We re-square, re-lock, and shim the boxes back to level before anything else happens.
- Melamine and laminate surfaces chalking, fading, and edge-band lifting. Sun and wind are the culprits. West-facing kitchen runs in Ontario bake under the same inland heat that cracks stucco and fades fencing. Edge banding lifts first, then the laminate face dulls. Depending on the run, we either re-band the edges or reface with new panels.
- Older CGI runs where the whole box has swollen past the joints. When multiple doors are peeling and sink bases are gone, patching becomes false economy. We will tell you replacement beats repair, and we will walk the numbers with you before any work starts.
CGI Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s citrus-and-dairy past is not ancient history in these kitchens. Downtown and near-downtown remodels regularly uncover buried agricultural piping and old oil tanks when we open the floor or dig for a new sink base. That is a condition you do not get in Rancho Cucamonga or Chino to the same degree. Before we set a CGI cabinet run or cut a sink base in an older Ontario home, we probe and scope. If there is an old tank or abandoned piping under the kitchen floor, it changes the demo plan, the plumbing layout, and sometimes the cabinet footprint. This is one reason we do not treat a CGI cabinet install as a flat-rate job. The soil and the history under the slab are part of the work.
CGI Models & Products We Service in Ontario
We service the CGI Ready-to-Assemble Shaker and raised-panel kitchen cabinet lines, the Euro-style flat-slab melamine series, and the vanity and bath cabinet collections. We also handle CGI quartz and laminate countertop offerings, and we coordinate those tops with the cabinet runs we reface or replace.
Our parts approach is simple. We use OEM CGI doors, drawer fronts, hinges, and matching panel stock when a single box or a short run needs to blend into an existing kitchen. We spec quality aftermarket soft-close hardware and plywood sink bases where OEM particleboard is the weak point. For fast Ontario turnaround, we keep common CGI hardware and matching panel stock in stock, and we order OEM components with enough lead time to avoid a second trip.

FAQs – CGI Construction in Ontario
Yes, in most cases. We order OEM CGI doors, drawer fronts, and panels in the same line and finish, and we match the existing reveals and hardware placement as closely as the boxes allow. If the original run has faded in the sun, we will show you the difference before you commit, so there are no surprises after install. Call (866) 472-1908 and we’ll take a look at the run you want to match.
Thermofoil and laminate door skins peel along the bottom rail because the dishwasher vents heat and moisture directly onto that edge, and Ontario’s dry summer heat makes the adhesive brittle and the laminate shrink. Once skin separates, it will not re-bond cleanly. We replace the affected doors and drawer fronts, and we adjust the dishwasher vent path or add a heat shield where it makes sense. An exact quote is a phone call away at (866) 472-1908.
Regularly, especially downtown and in the older grid neighborhoods that grew out of Ontario’s citrus and dairy farmland. Buried oil tanks and abandoned irrigation piping show up under kitchen floors more often than homeowners expect. We probe and scope before we cut any slab or set a new CGI sink base, and if we find something, we bring in the right licensed trades to handle it before construction continues.
Usually both. Ontario’s expansive soils shift slab-on-grade floors, and that movement racks the cam-lock and dowel joints in RTA cabinets. The doors drag because the boxes are no longer square, not because the hinges failed. We re-square and re-lock the boxes, shim them level to the floor, and only then adjust the doors. That sequence matters. Call (866) 472-1908 and we’ll assess whether it is a floor issue, a box issue, or both.
In inland Ontario heat, quartz holds up better than laminate. Laminate edges lift and chalk under sun and dry air, and quartz does not. If you are replacing a splintered or delaminated countertop anyway, upgrading from laminate to quartz typically adds $2,000 – $6,500 to the countertop scope, and it will outlast the cabinet boxes underneath it. Call (866) 472-1908 for an exact number on your kitchen.
