Why Rancho Cucamonga Homeowners Choose CGI Construction
Rowan Construction Group provides CGI service in Rancho Cucamonga for kitchen and bath products across the 91730 and 91764 ZIP codes, from cabinet installation and refacing to quartz countertop replacement and full kitchen remodeling. We’re not affiliated with or authorized by CGI - we’re an independent firm that has completed hundreds of CGI installations here since 2007, and we back our work with a written price before any tool comes out and a 365-Day Done Right Promise backed by The Haven Standard.
CGI’s Ready-to-Assemble Shaker lines and Euro-style frameless boxes show up in a lot of Rancho Cucamonga homes, especially the 1980s-2000s tract stock that’s now hitting the 30-40-year mark in neighborhoods like Alta Loma and near Etiwanda Heights Town Center. We’ve replaced swollen sink bases in those kitchens, rehung delaminated doors above dishwashers, and swapped out quartz with chipped sink edges from over-tightened undermount clips. The work is specific to CGI’s materials and construction methods, and we document every step with photos you’ll receive at closeout. Call (909) 373-9612 to schedule your free estimate.
Why Trust Rowan Construction Group Rancho Cucamonga for Your CGI Construction?
Our crews know CGI’s product lines down to the hinge bore pattern and the edge-banding thickness on their RTA cabinet doors. We’ve installed CGI Shaker kitchens in Rancho Cucamonga tract homes near Milliken Ranch and replaced CGI quartz countertops in Etiwanda Heights properties where the original installer spot-bonded the sink cutout and left the edge vulnerable to chipping. That depth matters because CGI’s thermofoil and particleboard construction responds to our local conditions in predictable ways - the Santa Ana winds blasting through the Cajon Pass don’t just stress roofing; they drive dust and heat into kitchen spaces where dishwasher steam and range exhaust already test cabinet finishes.
Grant Rowan, our owner, trained at Los Angeles Trade-Technical College in framing and finish carpentry before building Rowan Construction Group in 2007. He’s worked stretches across Rancho Cucamonga, including renovation work near the Cucamonga Winery Historical Landmark corridor, and he’s particular about documentation: written scopes, itemized change orders, and photos at every stage so you know where your money went. Under Clause 1 of The Haven Standard, the price is written before anyone starts. No exceptions. We use CGI OEM hinges, drawer slides, and touch-up kits when available, but for cabinet boxes and countertops we often specify equivalent or better aftermarket components that outlast the original. The 365-Day Done Right Promise is printed on every page, not hidden behind an asterisk.
Common CGI Construction Problems We Fix in Rancho Cucamonga

- Thermofoil peeling and delamination on Shaker cabinet doors near the dishwasher and range. The heat and moisture cycling in Rancho Cucamonga kitchens - especially during Santa Ana wind events when exhaust fans work overtime - breaks down CGI’s thermofoil adhesive along the bottom rail and stile joints. We see this most in homes near South Etiwanda Avenue where original 1990s installations are still in service. The fix isn’t a touch-up pen; it’s removing the affected doors, assessing the substrate, and installing CGI-matched replacements with upgraded soft-close hardware that reduces the slam stress that accelerates edge failure.
- Particleboard cabinet boxes swelling at toe kicks and sink bases. CGI’s RTA and frameless lines use particleboard cores that wick moisture from slab leaks, dishwasher drain failures, or even the alluvial soil moisture that rises through Rancho Cucamonga’s slab-on-grade foundations in older tracts. Once swollen, the box loses structural integrity and the drawer slides bind. We replace the box with a plywood equivalent, seal the base with a moisture barrier, and reinstall the original or matched CGI doors.
- Quartz countertop edge chipping at sink cutouts. CGI quartz slabs look solid, but the sink cutout is the stress concentrator. When undermount clips are over-tightened during installation - a common shortcut we find in competitor work - the edge develops hairline fractures that propagate into visible chips. We remove the damaged section, fabricate a new cutout with proper relief grooves, and set the replacement with balanced clip torque and full silicone bedding.
- Grout cracking and tile debonding in shower pans. CGI ceramic and porcelain tile installs fail when thinset is spot-bonded instead of fully back-buttered, especially on Rancho Cucamonga’s older slab substrates that shift slightly with seasonal soil expansion. Water penetrates the voids, the pan flexes, and the tile pops. We strip to the substrate, install a traditional mortar bed or preformed foam base depending on the floor condition, and set new tile with complete coverage.
- Drawer slide failure in Euro-style frameless boxes. CGI’s standard roller slides wear out at 15-20 years of use, which means the original hardware in Alta Loma’s 1990s-2000s housing stock is failing now. The drawers sag, bind, or drop out entirely. We upgrade to Blumotion-style soft-close undermount slides with full-extension capability - a functional improvement over the original spec that doesn’t require modifying the CGI box construction.
Before
AfterCGI Parts & Our Repair-vs-Replace Approach
We stock CGI OEM hinges, drawer slides, toe-kick clips, and touch-up kits at our Rancho Cucamonga facility for same-day repairs when the failure is isolated. But we’re honest about when patching stops making sense. If a CGI cabinet run has three or more swollen boxes or delaminated doors, we quote full replacement rather than repairs that will fail again within a year. The particleboard substrate doesn’t recover from moisture saturation, and thermofoil delamination spreads once the adhesive line is breached.
For countertops, we source equivalent or better quartz and granite from Cambria, Caesarstone, and Silestone - brands we vet the same way we vet CGI’s material - so the written quote reflects honest numbers rather than inflated single-brand pricing. The decision is always yours, but we show you the photos, explain the failure mode, and put both options in writing before any work starts. Call (909) 373-9612 for a free estimate with line-item pricing.
Our CGI Service Process - Step by Step

- 1
Diagnosis with photo documentation. We inspect your CGI installation for the specific failure patterns we’ve outlined above - thermofoil condition, box swelling, countertop edge integrity, tile bond. Every finding is photographed and added to your project file before we leave.
- 2
Written quote with scope and price. Under The Haven Standard Clause 1, you receive a flat written price with a written scope of work. No “call for a quote.” No range that shifts later. The number includes materials, labor, and the 365-Day Done Right Promise.
- 3
Repair or install with signed change order protection. If we discover additional damage during work - a sink base box that’s worse than surface inspection suggested, for example - we stop, photograph, and present a signed change order before proceeding. This discipline is why our projects finish within a few percent of the agreed price.
- 4
Testing and quality check. Cabinet doors are cycled 50 times to verify hinge alignment and soft-close function. Countertop seams are checked with a straightedge. Tile shower pans are flood-tested for 24 hours when local permit requirements apply.
- 5
Warranty documentation and photo record delivery. You leave with a written warranty, the complete photo record of what was found and what was done, and our direct line. If it’s not done right, we make it right - that’s the promise printed on every page.
CGI Products We Service & Install in Rancho Cucamonga
We work with CGI’s full residential line: Ready-to-Assemble Shaker-style kitchen cabinets in standard and custom sizes; Euro-style frameless cabinet boxes with matching drawer systems; quartz and granite countertop slabs in 2cm and 3cm thicknesses; and ceramic and porcelain floor and wall tile in field, mosaic, and accent formats. For Rancho Cucamonga’s Inland Empire climate, we pay particular attention to CGI’s thermofoil color stability in sustained heat - lighter finishes hold up better near west-facing windows - and we stock locally the hinge and slide hardware that fails most often in our market. If your CGI product is discontinued, we source equivalent or better replacements from our fifty-plus vetted brands and match the aesthetic without compromising function.
We Also Service These Brands

Rowan Construction Group Rancho Cucamonga is not a single-brand shop. We install and repair KraftMaid and Wellborn cabinets, Cambria and Silestone countertops, Kohler and Toto fixtures, and dozens of other vetted brands. Our multi-brand depth means we specify what fits your project and budget, not what a manufacturer requires us to push. The written quote compares real options with real numbers.
FAQs - CGI Construction Service in Rancho Cucamonga
Yes, when CGI’s current Shaker line matches your existing profile and finish code. We order CGI-matched replacement doors with upgraded soft-close hinges, or source equivalent Shaker profiles from KraftMaid or Wellborn if CGI has discontinued your color. Call (909) 373-9612 and we’ll verify the match from your door sample or photos.
We recommend refacing when the cabinet boxes are sound - no swelling, no structural compromise, and the interior layout still functions for your kitchen workflow. Full replacement makes sense when three or more boxes are damaged, the drawer systems are obsolete, or you want to reconfigure the layout. We show you photos of your boxes and explain both options in writing before you decide.
Sustained temperatures above 110°F can stress quartz resin binders, but the bigger issue in Rancho Cucamonga is thermal shock from hot cookware placed directly on the surface. CGI quartz is heat-resistant, not heat-proof. We include care instructions with every install and recommend trivets near cooktops, especially in west-facing kitchens that bake in afternoon sun.
The thermofoil adhesive fails from repeated heat and moisture cycling - dishwasher steam rises, condenses on the door bottom rail, and breaks the bond over 5-10 years. We can replace just the affected doors and drawer fronts, upgrade to moisture-resistant MDF cores, and install a vapor barrier under the sink base to prevent recurrence. Full cabinet replacement is only necessary if the boxes themselves are compromised. Call (909) 373-9612 for an exact quote - estimates are free.
We choose based on your existing slab condition. Traditional mortar beds handle the slight flex in older Rancho Cucamonga slab-on-grade foundations better, but preformed foam bases from Schluter or Wedi install faster and reduce weight load. We inspect for level, document the substrate with photos, and specify the method in your written quote.
