CGI Construction in Ontario, CA | Pinecrest Contractors
We provide independent CGI cabinet and countertop service across Ontario, from the 1950s stucco tracts east of Euclid Avenue to the older strip retail along Holt and Mission Boulevards. The one thing that makes our CGI work here different is that we know exactly how Ontario’s heat and clay-heavy soil stress these cabinets in ways a generic installer won’t catch. If you’re dealing with peeling thermofoil doors or a swollen sink base, call (855) 702-1622 and we’ll give you an honest read.
Why Ontario Residents Choose Us for CGI Service
We have spent years pulling apart and rebuilding CGI cabinetry in Ontario homes, so we know where builder-grade laminate boxes and thermofoil doors fail first, and we know which repairs actually hold up. We’re independent. Not authorized or partnered with CGI. That matters because we tell you what the material needs rather than reading from a manufacturer script. If a box is sound, we’ll repair it. If it’s water-swollen or the layout fights the room, we’ll say so plainly and show you the options, including semi-custom CGI maple or oak lines when replacement makes sense.
Gil Rourke, the owner here at Pinecrest Contractors, started in construction at seventeen and has spent decades working every phase of residential and light commercial builds. The right material in the right place is where the job starts, and in Ontario’s older tracts that usually means checking what’s behind the cabinet before we quote the cabinet.
We’re a full-scope general contractor, not a specialty cabinet shop. That means when a CGI tear-out exposes a broken cast-iron drain or a galvanized supply stub that has to move, we handle the plumbing, the drywall, the cabinet install, and the countertop under one contract. You get one point of accountability from the first cut to the final caulk line.

Common CGI Construction Problems We Solve in Ontario
- Thermofoil peeling and blistering on door fronts. Ontario summers routinely push past 100°F from June through September, and homes closed up tight during the day cook their kitchens. CGI thermofoil doors delaminate under that sustained heat. We see it most often on cabinets that face west windows or sit against exterior walls with no shade.
- Particleboard and MDF box swelling around sinks and dishwashers. Original cast-iron drain lines in 1950s through 1970s Ontario homes leak and sweat, especially along the sink wall. That moisture wicks straight into the CGI particleboard boxes and the bottoms let go. Patching a swollen box is a waste of your money, and we won’t sell you that.
- Laminate countertop seams lifting and backsplash caulk failing. Ontario’s clay-heavy soils expand and contract with seasonal moisture, and older slab and raised-foundation homes move more than people realize. When the wall framing shifts, the cabinets rack slightly, the laminate seam at the corner pulls apart, and the integrated backsplash caulk cracks away from the wall.
- Drawer glides and hinges loosening as boxes pull from studs. The same seasonal movement that opens countertop seams also loosens the cabinet mounting. You’ll notice drawers that drag on the face frame or doors that won’t stay closed. We re-secure boxes to studs and replace worn CGI hardware before it gets worse.
- Discontinued CGI lines and mismatched additions. Homeowners adding a kitchen island or replacing a run of cabinets often find their original CGI line is long discontinued. We source matching doors when the box is sound, and when it isn’t, we match the finish and fit with a current semi-custom line rather than leaving you with a patchwork kitchen.
CGI Service in Ontario: What Local Conditions Mean for Your Equipment
In central Ontario, specifically the 91761 and 91762 ZIP codes, a CGI cabinet tear-out routinely turns up something the newer east-side tract homes never deal with. The original cast-iron drain lines and galvanized supply stubs behind the sink wall are at the end of their life, and the city won’t sign off on a kitchen remodel or ADU addition until they’re replaced. That means a countertop-and-cabinet job that looked like a two-day swap becomes a plumbing-and-drywall job first. We plan for that from the start, because we have done enough of these to know the inspection is coming. On a 1968 stucco ranch off Holt Boulevard, we pulled a CGI laminate kitchen to find the sink base swollen and the original cast-iron drain cracked at the trap arm. After the lateral was replaced and the wall opened for galvanized-to-PEX stub-outs, we set new CGI maple cabinets with soft-close aftermarket glides and a quartz top, finished before the 10 a.m. heat pushed the adhesive past its open time. That is what Ontario-specific CGI work actually looks like.
Concrete and adhesive work here gets scheduled at dawn during summer because by mid-morning the mix is setting faster than it can be finished. We apply the same thinking to countertop adhesive and cabinet shimming. It changes how a job is sequenced, and it changes what we tell you about timing.
CGI Models & Products We Service in Ontario
We work on CGI builder-grade laminate base cabinets, the kind original to many 1960s and 70s Ontario tract kitchens. We also service CGI thermofoil and melamine doors and drawer fronts, post-form laminate countertops with integrated backsplash, and the semi-custom maple and oak CGI lines used in mid-range kitchen updates. Our parts approach is simple. When the box is structurally sound, we source OEM CGI hinges, glides, and replacement doors to keep the job consistent. When the original CGI hardware is obsolete or wasn’t great to begin with, we move you to quality aftermarket soft-close hardware that fits and lasts. We also offer cabinet refacing where the boxes justify it, and quartz or granite tops when it’s time to leave laminate behind.

FAQs – CGI Construction in Ontario
If the boxes are dry and square, refacing with new doors and drawer fronts is a solid option, and we do it regularly. If the particleboard boxes have swollen from sink leaks or the heat has warped the frames, refacing won’t hold and you’d be paying twice. We’ll tell you which one you have before you spend anything.
In central Ontario, 91761 and 91762 especially, yes, that’s common. The original cast-iron drains and galvanized supply lines behind the sink are usually past their service life, and the city will require replacement before an inspection passes on a remodel or addition. We coordinate that plumbing work as part of the job so it doesn’t sit on you to find another contractor.
Sometimes we can source matching doors or drawer fronts if the line was recently discontinued. When we can’t, we match the finish and door profile with a current semi-custom line and do the whole run so the kitchen reads as one. You won’t get a close-enough island that looks close-enough.
Ontario’s summer heat shortens adhesive open times and makes thermofoil more likely to peel on sun-facing cabinet runs. We schedule adhesive and countertop work early in the day, store materials out of direct sun, and use fasteners that stand up to the seasonal movement of clay-soil foundations. It’s not fussy, it’s just what works here.
A full CGI cabinet replacement in an Ontario kitchen usually runs $4,000 to $13,000, with countertops adding another $2,000 to $6,500 depending on material. If plumbing replacement behind the sink wall is required, that’s quoted separately before we start. Call (855) 702-1622 for an exact quote, the estimate is free.
