CGI Construction in Ontario, CA | Workshop Contractors
We’re an independent construction and remodeling crew offering our Home Remodeling in Ontario, installing, refacing, and repairing CGI cabinetry across the city. The thing that separates our CGI work here from everywhere else is simple: we know what this city’s slab-on-grade clay soils and triple-digit summers do to a cabinet box over time, and we build for it. If you’re planning a kitchen or bath update with CGI cabinets in Ontario, call (844) 384-3361 for a free estimate.
Why Ontario Residents Choose Us for CGI Service
Noel Figueroa grew up in the Vineyard neighborhood of Ontario, where half the houses on his street were built by the same generation of tradesmen who eventually handed him his first framing hammer. He learned the fundamentals at Chaffey College, where the construction technology program put him on job sites before he was old enough to rent a truck, including early experience with CGI service in Chino. That matters when we’re working on a 1960s tract home off Holt Blvd and the floor isn’t level anymore.
We’re not a CGI dealer. We’re a CGI sales & service independent crew that sources CGI cabinets, refacing components, and finish-matched parts through authorized distribution channels without being tied to the manufacturer. That independence means we specify the CGI line that fits your layout and budget, not the one a showroom is pushing. We install the boxes, hang the doors, square the frames, and stand behind the work ourselves. One contract. One crew. Every trade from the roof down to the pavers.

Common CGI Construction Problems We Solve in Ontario
- RTA boxes separating at the corners. CGI ready-to-assemble cabinets assembled in Ontario’s dry inland heat with under-driven or missing glue joints separate at the corner within a few seasons. This shows up worst on upper cabinets carrying heavy dishware. We re-glue, square, and re-cam every box we touch.
- Door and drawer faces warping on sun-exposed walls. South- and west-facing kitchen walls in Ontario take brutal summer sun, especially with original single-pane windows. CGI door and drawer faces delaminate or bow when surface temps climb. We replace with finish-matched doors and address the heat source where possible.
- Hinge plates loosening and doors sagging. This is the most common call we get from Ontario homeowners. Hinge screws strip in the cabinet face over time, doors drop, and the reveal lines go crooked. We re-drill, re-hang, and use OEM CGI hinges so alignment stays true.
- Particleboard shelves sagging under load. CGI semi-custom units with particleboard or MDF core shelves creep under cast-iron and small-appliance weight. Ontario’s heat-and-dry summer cycle accelerates that creep. We replace sagging shelves with braced all-plywood stock.
- Toe kicks and end panels swelling at floor level. In older Ontario tract kitchens, slab moisture migrates up through tile grout and unfinished edges. Toe kicks, fillers, and end panels swell and crack. When we open a kitchen for a remodel, this is one of the first things we check.
CGI Service in Ontario: What Local Conditions Mean for Your Equipment
In the post-war tract homes south of Holt Blvd, CGI cabinet runs were set on slab-on-grade floors over expansive clay that shifts seasonally. The ground under those homes isn’t static. It swells in wet winters and contracts through the dry Ontario summers, and that movement transfers straight up into the cabinets. A kitchen that was plumb and square in 1962 is often carrying a half-inch of floor deflection today. Before we install or reface a single CGI box in these neighborhoods, we check the slab for cracks and out-of-level runs. If the floor has moved, we correct for it before the new doors go on. Most CGI pages talk about door styles. This one tells Ontario homeowners how the city’s clay soils and inland heat actually stress cabinet boxes, and how we fix it before the finish work starts.
CGI Models & Products We Service in Ontario
We work across the full CGI line: Ready-to-Assemble all-plywood shaker and slab cabinets used in Ontario kitchen remodels, semi-custom maple and painted door styles for full kitchen builds, vanity and bath cabinet collections paired with quartz tops, and cabinet refacing doors and drawer fronts for partial kitchen updates. For parts, we use OEM CGI hinges, drawer glides, and replacement doors wherever the box is structurally sound. The original hardware matches the cabinet’s drilling and keeps alignment true. Where a CGI box has failed at the joint or swelled at the base, we replace that unit with a quality all-plywood carcass rather than patching it. We stock common hinges and glide hardware locally so Ontario jobs don’t stall waiting on a shipment.

AfterCGI Service Pricing in Ontario
What you’ll pay depends on scope: whether we’re refacing existing boxes or pulling everything out and rebuilding. Here’s what we see across Ontario right now:
| Service | Typical Ontario Range |
|---|---|
| Full Kitchen Remodeling | $14,000 – $45,000 |
| Cabinet Installation & Refacing | $4,000 – $13,000 |
| Bathroom Vanity Installation | $800 – $3,000 |
The wild card in Ontario is the slab. If we find floor deflection under the existing cabinet run, leveling and shimming adds labor before the new boxes go in. A free estimate from us includes a level check on the floor and a straight-edge look at the walls. Call (844) 384-3361 for an exact number.

FAQs – CGI Construction in Ontario
Reface and re-hinge when the boxes are straight and dry. Replace when the slab or wall moisture has already compromised the core. In older Ontario homes south of Holt Blvd, we often find the uppers are still sound while the base units have swelled at the floor line. We’ll tell you honestly which is which and price each option separately. Call (844) 384-3361 for a free assessment.
They hold up well when assembled correctly, but many RTA boxes in Ontario fail because they were built with under-driven cams and insufficient glue in a dry climate that shrinks wood fast. When we install CGI RTA, we glue and square every joint before the cams go tight. That changes the lifespan.
Expansive clay under slab-on-grade homes in Ontario moves with the seasons. That movement shifts floors, which throws cabinet runs out of level, which causes doors to bind and boxes to pull apart at the wall. We check for slab cracks and out-of-level runs before we install anything, and we shim or correct the base so the cabinets start square.
No. We’re an independent contractor, not a CGI-authorized dealer and not manufacturer-affiliated. That’s the point. We specify the CGI product that works for your layout and budget, not the line a dealer is trying to move. We source through authorized distribution channels and we stand behind our installation ourselves.
Cabinet refacing in Ontario typically runs $4,000 to $13,000 depending on how many doors, whether we’re replacing drawer fronts, and what condition the boxes are in. A small kitchen update with new counters and refaced cabinets can land anywhere from $9,000 to $20,000. Call (844) 384-3361 and we’ll give you a line-item quote, free.
