CWS Construction in Ontario, CA | Stallion Contractors
We provide independent CWS cabinet installation, countertop fabrication, and full kitchen remodeling across Ontario, covering the 91758, 91761, 91762, and 91764 ZIP codes. What sets our CWS work apart here is that we plan every tear-out around South Coast AQMD Rule 403 dust-control requirements, which most out-of-area builders don’t even know exist until the inspector shows up. If you’re pricing a CWS kitchen or bath project in Ontario, call (855) 600-3192 and we’ll walk you through what the job actually requires, including the compliance side most quotes leave out.

Stallion Contractors is an independent contractor. We are not authorized, sponsored, or endorsed by CWS, and we don’t pretend otherwise. What we are is a crew that has spent years installing CWS cabinetry, countertops, and surfacing in Inland Empire kitchens and baths, so we know how their box construction, door styles, and finish options hold up in real Ontario homes. Ruben Montoya runs our team, and he grew up in Colton, right off Pepper Avenue, where he learned early that the Inland Empire soil, sun, and wind punish shortcuts. That background shows up in how we level cabinets, support quartz, and sequence demolition around air-quality rules.
Why Ontario Residents Choose Us for CWS Service
Most contractors can hang a cabinet box. Fewer know how a CWS Charleston or Hanover door style should sit on a shimmed, leveled run in a 1960s tract home with floors that have moved half an inch since Kennedy was in office. We do. Our work on CWS cabinetry and countertops in Ontario comes out of years of seeing where these products fail, where they hold up, and what the right fix costs.
We source genuine CWS doors, drawer fronts, and hardware when you want a matched finish. When original parts are discontinued or priced past reason, we use quality aftermarket glides, hinges, and levelers and tell you exactly what you’re getting. That honesty matters on semi-custom CWS runs ordered for infill apartment and ADU kitchens, where a wrong substitution shows up six months later as a misaligned drawer or a hinge that won’t hold a soft-close. We also pull permits where Ontario requires them and schedule inspections so the closeout is clean, not a scramble.
Ruben’s father was a finish carpenter, which is partly why he still pays more attention to the final ten percent of a job than most contractors pay to the first ninety. Good work doesn’t need a sales pitch – it needs the right materials and someone who knows what they’re doing.

Common CWS Construction Problems We Solve in Ontario
- Swollen MDF and particleboard boxes at the toe kick and sink base. We see this all over Ontario’s 1950s-70s tract stock, where a supply line or disposal leak behind a CWS cabinet goes unnoticed for months and the box soaks it up like a sponge. We replace the damaged boxes, shim the run level, and reset doors so they close square again.
- Peeling thermofoil and laminate door faces along the bottom rail. Ontario summers hit hard, and west-facing kitchens with sliding doors cook those door faces year after year. The laminate lifts, the thermofoil delaminates, and the fix is either replacement doors or a reface, depending on how far the heat damage has crept.
- Quartz seam and edge failures from skimping on substrate support. Older Ontario homes have out-of-level floors, and when a prior installer sets CWS quartz directly on cabinets without a proper subtop, the seams open and edges chip. We pull the tops, level the run, add the subtop, and reset the stone so it actually stays put.
- Drawer glide and hinge fatigue on ADU and garage-conversion kitchens. Unpermitted conversions in Ontario often skip ventilation, so humidity builds up and wears out glides and hinges on CWS semi-custom runs faster than they should. We replace the hardware and correct the ventilation issue so the new parts don’t fail the same way.
- Misaligned door and drawer fronts on builder-grade CWS installs. Fast tract-home installs leave doors gapped unevenly. We realign, adjust, and replace hinges where needed so the run looks like it was installed with care, not against a deadline.
CWS Service in Ontario: What Local Conditions Mean for Your Equipment
Any grading, demolition, or cabinet tear-out we do in Ontario has to be paired with water trucks and soil stabilizers under South Coast AQMD Rule 403. That’s true even on a small kitchen gut in a 91761 tract home. The rule is far more aggressive in Ontario than in neighboring cities because the city sits inside the South Coast air basin, and the logistics boom has put thousands of square feet of disturbed soil into the air every year. For a CWS kitchen remodel, that means we budget for dust suppression before we swing a hammer, and we sequence demolition so the dust stays down and the inspector stays happy. On a 1962 tract home off Euclid Avenue near the 91762 line, we pulled a CWS Charleston kitchen with swollen particleboard sink bases and peeling thermofoil doors, then set new CWS boxes on shimmed, leveled subfloor and hung quartz tops with a proper subtop. Before demo we ran water trucks to hold Rule 403 dust down. The finished kitchen closed out with the owner keeping the original uppers refaced instead of replaced.
CWS Models & Products We Service in Ontario
Our CWS service in Chino and Ontario installs and repairs CWS Charleston and Hanover door-style cabinet collections, the lines sold through kitchen-and-bath dealers for tract-home remodels. We also handle CWS quartz and granite countertop programs specified for Ontario’s mid-century and infill kitchens, plus CWS vanity and bath cabinet lines paired with Kohler and Delta fixtures. On the semi-custom side, we work with CWS cabinet runs ordered for infill apartment and ADU kitchens, where the cabinet spec has to match a tighter footprint and a faster schedule. Parts-wise, we keep common hardware in stock for Ontario turnaround, and we order genuine CWS doors and drawer fronts when a matched finish matters. When original parts are discontinued, we use quality aftermarket glides, hinges, and levelers and tell you before we install them.

FAQs – CWS Construction in Ontario
Yes, under South Coast AQMD Rule 403 any grading or demolition that disturbs soil or creates visible dust requires water trucks, soil stabilizers, or other approved suppression. That applies to a small kitchen gut on a 91761 tract home the same as it does to a logistics warehouse site. We plan and price for compliance on every Ontario CWS job. Call (855) 600-3192 and we’ll include the dust-control line in your quote.
Yes, when the boxes are sound and only the doors, drawer fronts, or finish are worn, refacing and re-boxing a CWS run often beats a full tear-out on cost and disruption. We tell owners honestly when refacing works and when the boxes are too far gone to save. Call (855) 600-3192 for a site look at your kitchen.
Yes, in most cases the doors can be replaced or the faces refinished, depending on how far the delamination has spread along the bottom rail. We match the CWS door style where possible so the repaired run looks consistent with the rest of the kitchen. Call (855) 600-3192 and we’ll tell you what your specific doors need.
Yes, we run cabinets and countertops as one scope, which means the CWS boxes get shimmed and leveled before the quartz or granite is measured and set. That’s the sequence that prevents seam and edge failures on out-of-level Ontario floors. Call (855) 600-3192 for a combined quote.
Santa Ana wind events complicate any work that involves dust, debris, or outdoor staging. We watch the forecast and schedule demolition and material staging for days when wind isn’t pushing dust toward neighbors or triggering AQMD enforcement. Call (855) 600-3192 and we’ll factor the seasonal wind pattern into your start date.
