CGI Construction in Fontana, CA | Elmwood Contractors
We provide independent Rialto CGI service across Fontana, from impact window and door replacements to Kwik-Kit enclosure work on commercial tenant improvements. We are not a CGI dealer or authorized warranty station, but we install and service their systems on a regular basis throughout the Inland Empire. The difference in Fontana is that CGI windows here often get specified for dock offices and warehouse tie-ins along the I-10 and I-210, not just residential retrofits, so the flashing and wind-load details get spec’d and inspected to commercial standards. For CGI work in Fontana, call Elmwood Contractors at (866) 253-8554.
Why Fontana Residents Choose Us for CGI Service
When a homeowner in Fontana searches for CGI construction work, they usually need one of two things: a contractor who actually knows how CGI units go into stucco openings, or someone who can fix a set of impact windows that’s been cooked by a decade of Inland Empire summers. We do both. Nolan Shepherd, our owner, grew up in Fullerton’s Sunny Hills neighborhood and spent his twenties on ground-up residential and light commercial projects across North Orange County. He’s pulled enough fogged dual-pane units out of stucco walls to see the exact point where someone skipped the flashing detail. We carry OEM CGI replacement parts – glazing units, rollers, hinges, locks, weatherseal – and we stock aftermarket equivalents for profiles CGI has discontinued. When we open up a Fontana window, we already know which of the two we’ll need. That saves homeowners in ZIP codes like 92335 and 92337 from waiting on parts that were never coming anyway.
We’re a Fontana service area contractor with brand depth across CGI’s product line, but we’re not affiliated with the manufacturer. That independence means we can tell you directly when a repair makes sense and when a full replacement saves you money over two years of chasing failures unit by unit.

Common CGI Construction Problems We Solve in Fontana
Here’s what we see most often when we service CGI systems in Fontana:
- Fogged dual-pane glazing from UV and heat. Fontana summers routinely top 100°F, and that bakes the desiccant in sealed units until the glass fogs. We replace the glazing with new OEM CGI units or a matched aftermarket equivalent, and we check the frame seal before putting it back.
- Baked-out weatherstripping and rattling frames. Santa Ana wind cycles dry out seals and gaskets until the sash rattles on every gust. Northern and eastern elevations on open Fontana lots take the worst of it. We re-gasket and adjust the hardware rather than telling you to live with the noise.
- Stucco-to-window interface leaks in 1980s-2000s east Fontana subdivisions. In 92336 and 92337, original builder-grade openings often never had proper flashing or weep screed behind the stucco. When the first window gets replaced, water finds the gap. We reset the opening, install flashing and weep details, and then set the new CGI unit.
- Hardware failure from dust intrusion. Fontana’s logistics-corridor environment puts a lot of fine dust into window tracks and roller assemblies. Sliding and hinged CGI units bind, jump track, or seize at the lock set before the glass ever fails. We clean, rebuild, or replace the hardware.
- Wind-driven infiltration after Santa Ana events. Older weatherseal on impact windows can’t hold up to sustained high wind once it gets stiff and cracked. We find the failed run and replace it, usually the same visit as the inspection.
CGI Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana’s buildout is dominated by tilt-up concrete industrial shells and tenant improvements along the I-10 and I-210. That’s the thing a lot of out-of-town contractors miss. A Glen Avon CGI service-spec window or enclosure package here is often part of a dock-office or warehouse-tie-in scope rather than a single-family swap, so the submittal, flashing, and wind-load details get scrutinized harder than they would on a residential job of the same size. What passes on a 1970s tract home in 92335 won’t pass on a commercial storefront off Valley Boulevard. Our crews work both, which means residential CGI jobs get commercial-grade flashing and sealing details as a matter of habit. We’ve pulled enough window submittals for Fontana tenant improvements to know the exact language inspectors want to see, and we carry that standard into every residential opening we cut.
CGI Models & Products We Service in Fontana
We service CGI hurricane-rated impact window and door systems common in Inland Empire stucco tract homes, CGI Kwik-Kit modular and prefabricated building units, high-heat high-UV replacement window and door units, and CGI glass and glazing packages used on commercial storefront and tenant-improvement work. On parts, our rule is simple: OEM CGI replacement parts wherever they’re still available, and quality aftermarket equivalents for discontinued profiles, with the customer told which we’re using and why. We regularly service CGI service in Woodcrest and CGI service in Bloomington, so we keep common Fontana units and parts moving through our inventory instead of special-ordering every time.

AfterCGI Service Pricing in Fontana
Here’s the range for the most common CGI scopes we bid in Fontana:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
What drives the cost is opening condition. A clean opening with intact flashing is a straightforward swap. A stucco opening that was flashed wrong thirty years ago takes demolition, reflashing, and re-trimming before the new unit goes in. Our free estimate includes the line-item breakdown for that work. Call (866) 253-8554 to schedule yours.

FAQs – CGI Construction in Fontana
No. We are an independent construction and remodeling contractor, not a CGI dealer or authorized warranty station. Our CGI experience comes from repeat field work across the Inland Empire, not a factory badge. We use OEM CGI parts wherever available and we’re upfront about the difference between our workmanship warranty and the manufacturer’s warranty. Call (866) 253-8554 if you have a specific CGI unit you want evaluated.
If the glass is fogged, replace the glazing unit. If the frame is racked or the opening flashing has already given out, replace the whole window. On a 1990s stucco-and-tile tract home in the 92336 grid, our crew pulled a set of CGI framed windows that had fogged dual-pane glass and weatherstripping baked brittle by years of 100-degree summers. We reset the openings with new flashing and weep screed, installed new OEM glazing units and hardware, and sealed the stucco returns – the homeowner stopped getting wind-driven dust and water at the north elevation before the next Santa Ana event. The deciding factor was the flashing, not the glass. Call (866) 253-8554 for an exact quote.
Yes, substantially. Commercial and industrial tenant improvements in Fontana require full submittals, wind-load calculations, and tighter inspection standards than a single-family swap. We bid those scopes with the engineering and paperwork already accounted for. It changes the price and the timeline, but it also means the same flashing and sealing discipline shows up on our residential Fontana jobs.
Strong sun bakes weatherstripping, gaskets, and glazing tape until they go stiff and crack. Santa Ana winds then push dust and wind-driven water through the failed seals. Hardware in tracks and rollers binds from dust intrusion along Fontana’s truck corridors. We see this on virtually every CGI system that’s been in place more than five years unchecked. Maintenance helps, but eventually the gaskets and hardware need replacement.
Yes. A home addition or ADU in Fontana gives you a clean chance to spec CGI impact windows and enclosures from day one, before the stucco goes on. We coordinate the window package with the framing, roofing, and waterproofing details under one project plan. ADU construction in Fontana runs $90,000 to $220,000 depending on size and finishes, and the CGI scope is a small but critical line item inside it. Call (866) 253-8554 to talk through your addition or ADU scope.
