CGI Construction in Foothill Ranch, CA | Milpitas Construction
We provide independent CGI service across Foothill Ranch, specializing in the original CGI components still in place throughout this 1990s master-planned community: concrete tile roofs, aluminum windows, builder-grade water heaters, and early HVAC split systems. What makes our CGI work different here is that we understand how those original installations age under Foothill Ranch’s specific conditions, from Santa Ana wind exposure to wildland-urban interface fire standards. Call (877) 752-4194 to schedule a free estimate.
Why Foothill Ranch Residents Choose Us for CGI Service
Most CGI service calls in Foothill Ranch are not routine. They involve original equipment that’s now 25 to 35 years old and has been sitting in a climate that punishes specific materials in specific ways. Ken Stafford and the Milpitas Construction team have worked on the tract homes and hillside properties of South Orange County long enough to know exactly what fails first and what’s still worth saving. We are an independent service provider, not affiliated with or authorized by CGI, and that matters. We call it like we see it. If a CGI concrete tile roof just needs underlayment replacement, we say so. If a window has lost its seal and is pumping conditioned air into the Santa Ana wind, we tell you to replace it rather than chase repairs that will not hold.
That honesty is why Foothill Ranch homeowners keep our number. We spec materials by name, show you exactly what’s going in, and stand behind the work.

Common CGI Construction Problems We Solve in Foothill Ranch
- Original CGI water heaters at end of life. The 40- and 50-gallon gas models installed in 1990s tract homes across Foothill Ranch are now 25 to 30 years old. We regularly see tank corrosion and failed thermocouples on these units. The real problem is leaks, which can quietly damage adjacent cabinetry in tight garage alcoves before anyone notices.
- CGI aluminum windows with blown seals. Those original aluminum-framed windows and sliding glass doors lose their seals quickly in Santa Ana winds and direct sun exposure. West-facing walls in Foothill Ranch are especially prone to fogged dual panes and water intrusion around the frames. Once the seal goes, the insulating value is gone.
- CGI concrete tile roof underlayment failure. The Mediterranean-style “Spanish S” concrete roof tiles themselves hold up remarkably well. The weak point is the underlayment beneath them. After 25-plus years, it dries out, cracks, and leaks at valleys and penetrations. We inspect the underlayment, not just the tiles.
- CGI HVAC systems with rusted heat exchangers. Early-1990s split systems installed by CGI are now past their expected service life. Rusted heat exchangers and failing capacitors are common, and the ductwork in Foothill Ranch’s tight attics can develop gaps that cut efficiency dramatically.
- Decking and exterior components nearing replacement. Foothill Ranch sits at the wildland-urban interface, and many original exterior materials are no longer in condition to perform against ember exposure. We assess current fire-resistant options when we’re on site.
CGI Service in Foothill Ranch: What Local Conditions Mean for Your Equipment
Foothill Ranch was one of the first master-planned communities in Orange County to adopt wildfire-resistant construction standards after the 1993 Laguna Fire. That means many original CGI-installed exterior components, like roof underlayment and decking, were already built to early Chapter 7A guidelines before most of the county even knew what those were. Sounds great, except those materials are now 25-plus years old and ready for replacement with current ember-resistant assemblies. A homeowner on Saddleback Ranch Road called us about a leak in their 1990s CGI concrete tile roof. We found the original underlayment had deteriorated and was letting water seep into the attic during heavy rains. Ken Stafford’s crew removed the tiles, replaced the underlayment with a fire-rated, self-adhering membrane meeting current Chapter 7A standards, and reinstalled the original tiles. That roof has another 20-plus years in it now. When you live this close to the Cleveland National Forest boundary, fire-resistant underlayment is not a code checkbox. It’s the only sensible repair.
CGI Models & Products We Service in Foothill Ranch
We work on the full range of CGI products found in Foothill Ranch tract homes: builder-grade 40- and 50-gallon gas water heaters, original aluminum-framed windows and sliding glass doors, Mediterranean concrete roof tiles, and early-1990s HVAC split systems with their original ductwork. For parts, we use OEM when it’s available to match original specifications. For common wear items like thermocouples, capacitors, and window seals, we source high-quality aftermarket equivalents that meet or exceed original specs. We do not load up our trucks with cheap universal parts just to make a fast repair. The goal is a fix that lasts in Foothill Ranch’s specific conditions.

FAQs – CGI Construction in Foothill Ranch
Can you repair my original CGI water heater, or should I replace it?
At 25 to 30 years old, a repair rarely makes sense. A failed thermocouple on a tank that old is usually just the first symptom; the tank itself is likely corroded and close to leaking. We recommend replacement with a modern unit and will not patch a water heater that’s about to flood your garage. Call (877) 752-4194 and we will assess yours honestly.
My CGI concrete tile roof is leaking. Do I need a full replacement?
Usually not. The concrete tiles themselves hold up well in Foothill Ranch. What fails is the underlayment beneath them. We can often remove the tiles, replace the underlayment with a fire-rated membrane that meets current Chapter 7A standards, and reinstall your original tiles. That costs far less than a full roof replacement and gives you another two decades of service.
Are CGI aluminum windows still available for replacement?
CGI’s original aluminum-framed windows from the 1990s are generally not available as new-old-stock. But you have good options. We specify modern windows from brands like PGT and ECO Window Systems that fit the original openings and meet current energy and fire-resistance requirements. For full Foothill Ranch service area coverage, we handle everything from single-window swaps to whole-house window replacement.
What wildfire-resistant upgrades make sense for my CGI-built home in Foothill Ranch?
Given your proximity to the Cleveland National Forest and the Santa Ana wind pattern, start with the roof assembly: fire-rated underlayment and ember-resistant vent covers. Next is decking if it’s original. Then exterior walls, especially stucco penetrations and any exposed wood trim. Milpitas Construction can assess your entire exterior and prioritize upgrades by actual fire exposure, not by what a skylight salesman would pitch.
Do you handle HOA approval for roof replacements?
Yes. Foothill Ranch is an HOA-governed master plan, and roofing material changes require architectural review before the city will even look at your permit. We prepare the submittal package, including material specifications and color samples, and manage the approval process as part of the contract. Call (877) 752-4194 and we will walk you through what your HOA specifically requires.
