CGI Construction in Los Serranos, CA | Elmwood Contractors
We’re Elmwood Contractors, and we provide independent CGI service across Los Serranos, CA from our base in Fullerton. We handle CGI cabinetry, countertops, exterior doors, windows, and roofing components on hillside homes throughout the 91709 ZIP code. The thing that separates our CGI work in Los Serranos from a flatland contractor’s is simple: we know how Chino Hills grading and slope ordinances affect every cabinet install, roof replacement, and wall penetration we touch. Call (866) 253-8554 for a free estimate.
Why Los Serranos Residents Choose Us for CGI Service
We’ve worked CGI products into kitchens, baths, and roofing systems across the Chino Hills foothills for years. We choose CGI materials on their merits, not a badge. No manufacturer authorization is implied. What we bring is field experience: we’ve seen what CGI cabinet boxes do after a decade of dry Inland Empire heat cycles, and we know which CGI window and door seals fail first on a slope-side lot when winter rain tracks into the framing. Nolan Shepherd, our owner, grew up in Fullerton’s Sunny Hills neighborhood and learned early which late-’60s houses would have foundation problems. He spent his twenties doing ground-up residential work across North Orange County, and for the past two decades he’s run Elmwood Contractors with one standard: the right material in the right place. Everything else is just catching up to that decision.
We name the brands going into your home before the contract is signed. For Los Serranos customers, that matters, because a hillside remodel needs materials that survive Santa Ana winds, intense sun, and short, hard rain events without callbacks.

Common CGI Construction Problems We Solve in Los Serranos
- Cabinet box and door failures from dry heat. Years of hot, dry summers in Los Serranos loosen hinges, swell particleboard, and delaminate veneer on CGI raised-panel and shaker doors common in 1980s-2000s homes. We replace sound boxes with new CGI doors and hardware, or rebuild the run when the box itself is compromised.
- Caulk and sealant breakdown at countertop-to-backsplash joints. Winter storm-driven moisture in Los Serranos gets into wall cavities when the seal between a CGI quartz or granite countertop and the backsplash fails. We strip the old caulk, re-seal with exterior-grade sealant, and sometimes tie the joint into a fresh moisture barrier.
- Roof and gutter edge failures under Santa Ana wind uplift. CGI roofing components on hillside lots take a beating from wind that doesn’t exist on flatland streets. Clogged downspouts dump runoff onto slopes, and edge flashing pulls loose. We re-flash, re-secure, and spec CGI gutter components that handle the wind load.
- Exterior door and window seal failures. Dried-out weatherstripping and failed flashing on CGI door and window units let seasonal rain track into framing on slope-side homes. We replace the weatherstripping and re-flash the opening, stopping the water before it reaches the wall cavity.
- Hillside drainage damage showing up inside kitchens and baths. On hillside streets off Los Serranos Country Club and Carbon Canyon, winter runoff backed up by deferred drainage maintenance routinely shows up as stained drywall, warped cabinet bases, and failing countertop seals. We fix the interior damage and address the exterior drainage detail that caused it.
CGI Service in Los Serranos: What Local Conditions Mean for Your Equipment
Los Serranos sits inside Chino Hills’ hillside grading and slope ordinance envelope, which means any CGI kitchen, addition, or re-roof we touch on a slope-side lot has to account for hillside permitting and drainage review that a flatland Chino or Ontario job never triggers. On the hillside streets off Carbon Canyon, we opened up a 1990s tract kitchen where years of dry heat had delaminated the CGI cabinet doors and popped the hinges. Behind the countertop, the wall was stained from winter storm runoff backing up through a failing exterior seal. We replaced the damaged cabinet run with new CGI boxes and shaker doors, re-flashed and sealed the exterior wall penetration, and tied the countertop-to-backsplash joint into a fresh moisture barrier. The homeowner got a kitchen that no longer grows a water stain every February. That’s the Los Serranos difference: the cabinet failure and the drainage failure were the same problem, and you can’t fix one without looking at the other.
CGI Models & Products We Service in Los Serranos
We service CGI kitchen and bath cabinetry lines, including the raised-panel and shaker door styles common in 1980s-2000s tract and semi-custom builds throughout Los Serranos. We also handle CGI quartz and granite countertop surfacing, CGI exterior door and window units (including impact-rated glazing options), and CGI roofing and gutter components used on Inland Empire re-roofs. Our parts approach is straightforward: we spec OEM CGI hinges, glides, and door hardware when the cabinet boxes are sound, and use quality aftermarket slides, sealants, and flashing when OEM equivalents aren’t practical. Never cheap substitutes that fail in two seasons. For a full look at what we carry across the CGI line, see our CGI sales & service page.

FAQs – CGI Construction in Los Serranos
Yes, and it’s the single biggest difference between working in Los Serranos and working in flatland Chino or Ontario. Any remodel on a slope-side lot inside the Chino Hills grading envelope triggers hillside permitting and drainage review. We handle the permit set, the site engineering, and the drainage details as part of the scope, so you’re not left managing the city on your own. Call (866) 253-8554 and we’ll walk you through what your specific lot requires.
Dry heat. Los Serranos summers bake interior spaces for months at a time, and the repeated expansion and contraction loosens hinges, swells particleboard, and delaminates veneer on CGI cabinet doors faster than you’d see in a coastal city. It’s not a CGI quality issue; it’s a climate issue. We replace sound boxes with new CGI doors and hardware, and we recommend sealing and ventilation details that slow the deterioration.
CGI roofing components are engineered for wind uplift, but installation matters more than the material. On Los Serranos hillside homes, we see roof edge failures where flashing was under-fastened or gutter components weren’t secured for the wind load. We re-flash and re-secure to CGI specification, and we spec gutter components that handle the runoff that Santa Ana seasons create.
Repair the CGI cabinet or component when the box and finish are intact. We spec OEM hinges, glides, and door hardware in those cases, and the repair holds for years. Replace when water damage or heat delamination has compromised the material itself. No amount of hardware fixes a swollen particleboard box. We’ll give you an honest read on which path your cabinets need. Call (866) 253-8554 for a free estimate, and we’ll tell you straight.
On hillside streets off Los Serranos Country Club and Carbon Canyon, winter storm runoff and deferred drainage maintenance routinely show up as cracked retaining walls, settling foundations, and water stains behind countertops and bathroom vanities. The runoff backs up against the exterior wall, penetrates through failed seals, and wicks into the framing. We fix the interior damage and correct the exterior drainage detail at the same time. Call (866) 253-8554 for an exact quote, and we’ll come look at your lot.
