CGI Construction in Ontario, CA | Mason Remodeling

We provide independent CGI cabinet installation, refacing, and repair across Ontario, and the short version is this: if your CGI thermofoil is peeling near the oven or your cabinet boxes are swelling under the sink, that’s where we start. The heat here isn’t like coastal California. Ontario summers sit above 100°F for stretches, and that inland dry heat attacks glued thermofoil in ways most cabinet brands never see west of the 15. Call (803) 680-2547 and tell us what you’re seeing. We’ll tell you straight whether it’s a repair, a reface, or a replacement, and you’ll have a written price before any work starts.

Why Ontario Residents Choose Us for CGI Service

A whole-home remodel with the living, dining and kitchen areas opened up

We’ve installed and serviced CGI’s kitchen and bath cabinetry across Ontario for years, which means we’ve seen the brand’s real-world quirks up close. Not from a spec sheet. From actual kitchens in Ontario Ranch, along Archibald Avenue, and in older pockets of the city where slab-on-grade foundations are the norm. Isaac Pruett, our owner, grew up in the San Fernando Valley and went through the construction technology program at LATTC in Los Angeles. He’s spent close to two decades remodeling homes, and he still checks every cabinet door alignment himself before calling a job done. You can read about our full CGI sales & service scope, but the point is this: we know what fails, why it fails here, and what’s actually worth fixing versus replacing.

Because we’re independent, not manufacturer-authorized, we give honest assessments. If a CGI cabinet is repairable, we say so. If it’s not, we tell you that too, with a written price either way. Every crew member who comes to your Ontario home for General Contractor - Ontario work is background-checked and identity-verified under the Threshold Standard, and you’ll get their name and photo before they arrive.

Common CGI Construction Problems We Solve in Ontario

  • Thermofoil delamination near heat sources. CGI’s glued thermofoil door skins peel away from the MDF core when exposed to repeated heat, and in Ontario that means ovens, dishwashers, and even south-facing windows in summer. We remove the delaminated panels, use high-temp adhesive on replacements, and address the venting that caused it.
  • Particleboard cabinet boxes crumbling under sinks. CGI boxes with particleboard core wick moisture from slow under-sink leaks and slab-on-grade dampness, which is a real factor in many Ontario homes. The bottom panels swell and crumble. We assess whether a box rebuild or full replacement makes more sense.
  • Soft-close hinge sag on older CGI doors. The standard concealed hinges CGI used on many lines lose tension after a few years, so doors hang uneven and stop closing flush. We source OEM CGI hinges when available, and use high-quality aftermarket hardware when they’re not.
  • Finish fading on darker thermofoil. UV exposure through windows fades CGI’s dark thermofoil finishes unevenly, especially on south-facing walls in Ontario. You’ll see lighter patches on the upper doors before the lower ones. We can match and replace individual doors rather than the whole run.
  • Drawer slides binding and sticking. After years of dry heat and dust, CGI drawer slides collect grit and start catching. Sometimes a cleaning and realignment fixes it; sometimes the bearings are shot. We’ll tell you which one you’re dealing with before we quote anything.

CGI Service in Ontario: What Local Conditions Mean for Your Equipment

A remodeled family room with new windows and a window seat

Here’s something you won’t find on a generic contractor page: Ontario’s inland location means summer highs regularly exceed 100°F, and that extreme dry heat accelerates adhesive failure in CGI’s thermofoil doors. Coastal customers in Los Angeles or San Diego don’t deal with the same sustained temperatures, so the same cabinets that hold up fine in Long Beach will delaminate above a stove in Ontario within two or three summers. We’ve rebuilt kitchens in Ontario Ranch where the uppers above the range had peeled after exactly that kind of exposure. The fix wasn’t just new doors. It was high-temp adhesive, proper venting, and an honest conversation about how heat moves through a kitchen that size. That’s the local knowledge that changes the quote. If you’re in Ontario and your CGI cabinets are starting to lift, it’s not a fluke and it’s not your fault. It’s the climate, and we know how to work with it.

We serve the wider Ontario service area, and we’ve done enough kitchens here to know which neighborhoods face this hardest. Homes with west-facing kitchens and limited cross-breeze get it worst.

CGI Models & Products We Service in Ontario

We work on the full range of CGI product lines: Ready-to-Assemble (RTA) Shaker-style kitchen cabinets, Thermofoil (TFL) cabinet doors and drawer fronts, our Bathroom Remodeling in Ontario Vanity Collections, and the Semi-Custom Cabinet Series. Our approach to parts is simple. We source OEM CGI hinges, drawer slides, and shelf pins when they’re available, because that keeps your warranty intact. When CGI has discontinued a line and OEM parts are no longer made, we use high-quality aftermarket hardware that often outlasts the original. For cabinet boxes that have swollen or delaminated, we tell you straight whether a reface or full replacement is the better investment. No pushing you toward the more expensive option because we’d rather sell a bigger job.
