CGI Construction in Santa Ana, CA | Rowan Construction Group

We provide independent CGI sales & service across Santa Ana, with a focus on impact windows and doors retrofitted into the city’s pre-1960 wood-frame bungalows. The one thing that makes CGI work here different from anywhere else in Orange County is the permit layer: the City of Santa Ana routinely requires as-built documentation for unpermitted additions before any window retrofit gets final sign-off. Call (470) 298-9650 for a written estimate that accounts for the full scope, not just the window swap.

Why Santa Ana Residents Choose Us for CGI Service

We have handled CGI repair in Irvine and installed CGI windows and doors across this city’s aging housing stock for years, and Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College before he ever touched a paying job. That training shows in how we approach a CGI retrofit: we look at what is behind the window first. In Santa Ana, that means opening the wall and finding shallow 2×4 stud bays, original lathe-and-plaster, or a rear addition from the 1980s that was never permitted. Most contractors measure the opening and order the unit. We measure the wall, the anchor points, and the permit file. We’re an independent contractor, not a CGI-authorized dealer, which means our recommendation is based on what the house needs, not what a manufacturer wants us to push. We use genuine CGI parts, but we’ll tell you when a repair no longer makes financial sense.

Common CGI Construction Problems We Solve in Santa Ana

Common CGI Construction Problems We Solve in Santa Ana
  • Failed or missing anchors on impact windows. Older Santa Ana walls were framed with 2×4 studs at 16 inches on center, and plenty of retrofit installers skipped structural anchoring entirely. When the Santa Ana winds hit 50-60 mph, an unanchored CGI Sentinel casement will rack in the opening, and you’ll feel the draft and hear the rattle.
  • Fogged insulated glass units in CGI Sentinel windows. South and west elevations in Santa Ana get hammered by decades of UV exposure and thermal cycling. The IG seal fails, moisture gets between the panes, and the once-clear view turns permanently cloudy. This is a replacement, not a repair.
  • Corroded or seized rollers on CGI Magnum sliding doors. Garage conversions across Logan and Lacy sit on slab-on-grade concrete over expansive clay. The slab settles unevenly, the track misaligns, and the rollers seize. Binding doors get forced, and forced doors break hardware.
  • Water intrusion at the sill flashing on CGI Estate windows. Retrofit panning over original lathe-and-plaster with no modern drainage plane was common practice years ago. The first heavy rain after a dry stretch reveals the staining on the interior sill.
  • Permit entanglement from unpermitted rear additions. The City of Santa Ana will not issue a permit for a window replacement if the window is in a room that was added without permits. The window job becomes a compliance job. We handle both.

CGI Service in Santa Ana: What Local Conditions Mean for Your Equipment

In the Logan and Willard neighborhoods specifically, the city’s mandatory as-built submittal for any permitted exterior window replacement often requires documenting and legalizing entire rear additions before a single CGI window can be installed. A homeowner calls us for three fogged windows on the back of the house. We pull the permit history and find the rear addition from 1984 was never recorded. Before Santa Ana’s Building Division will release the permit, we need to produce drawings showing the addition’s footprint, foundation type, and electrical. That makes a window retrofit the catalyst for whole-envelope code compliance rather than an isolated upgrade. This does not happen in Irvine or Mission Viejo, where the housing stock is post-1970 and mostly permitted from day one. In Santa Ana, the window is the door to the rest of the file. We prepare our customers for that reality before the first wall is opened, and it’s written into the estimate.

We work on the full CGI residential line that appears in Santa Ana homes. The Sentinel Series impact-resistant casements and picture windows show up on original 1930s-1950s casement replacements. The Estate Collection vinyl single-hungs and sliders are common in 1980s additions. The Classic Series aluminum storefronts and sliding doors appear in older garage conversions, and the Magnum Series heavy-duty impact sliders are the go-to for patios facing the wind. We use genuine CGI replacement parts-sash balances, rollers, weatherstripping, and hardware-sourced through independent distributors. When a part is obsolete on an older CGI line, we specify certified aftermarket parts engineered for impact-rated assemblies, never a generic hardware-store substitute. For windows with failed IG units or corroded frames, we recommend replacement when repair cost exceeds 60% of a new unit.
