CGI Construction in Los Angeles, CA | Mason Remodeling Co Los Angeles
We provide independent CGI window and door service across Los Angeles, from the flats of Van Nuys to the hills of Silver Lake. The one thing that makes our CGI work different here is that we’re not just swapping glass, we’re coordinating your windows with the seismic, wildfire, and hillside realities of this city. If you need CGI windows replaced, repaired, or installed as part of a retrofit, call (213) 632-5711 for a free estimate.
Why Los Angeles Residents Choose Us for CGI Service
Mason Remodeling Co has decades of hands-on experience with CGI-brand windows and doors in LA’s structural and seismic retrofit landscape. We’re not an authorized dealer. We’re a General Contractor - Los Angeles that has installed, repaired, and replaced CGI products in hundreds of local homes. That independence means we give you straight answers about what a repair will cost and whether it’s worth doing, without a sales quota behind it.
Isaac Pruett grew up in the San Fernando Valley and trained in construction technology at Los Angeles Trade-Technical College downtown. He has spent the better part of two decades working residential and light commercial jobs across Los Angeles County. When we send a crew to your home, you get the technician’s name and photo before the visit, and a photo ID badge at the door. That’s the Threshold Standard, and it’s how every job runs. For genuine CGI sales & service, you want someone who knows the product line and the city. We know both.

Common CGI Construction Problems We Solve in Los Angeles
CGI windows and doors are built tough, but Los Angeles finds ways to test them. Here are the failures we see most often.
- Corner stress and misalignment in hillside homes. Many LA hillside foundations were poured before modern seismic codes, and they move. We routinely see CGI window frames showing stress at corners from foundation movement or seismic settling, which leads to misalignment and air leaks. Fixing this often means addressing the rough opening before the window itself.
- Edge fogging in laminated glass from UV and heat cycling. Older CGI impact windows with laminated glass can develop edge fogging when the seal is compromised by LA’s intense summer sun and the daily temperature swing between hot days and cool nights. Once the seal fails, the only real fix is glass replacement.
- Binding multi-point locks on large sliding doors. CGI multi-point locking hardware is precise equipment. It does not forgive an out-of-square opening. In pre-1980 LA remodels, those openings are everywhere. We often find the door was installed into an opening that had settled, and the hardware binds or fails prematurely.
- Sun-damaged screens on west-facing elevations. West-facing windows in neighborhoods like Culver City or Venice take direct afternoon sun year-round. CGI screens on those elevations degrade faster than anywhere else on the house, with warped frames and brittle mesh that need replacement far more often than coastal-facing windows.
- Failed flashing and water intrusion around stucco exteriors. Most LA homes are wood-frame with stucco. When the flashing between a CGI window and the stucco fails, water gets in. It is slow, and it is often invisible until the damage is done. We trace the leak, repair the opening, and reflash to current code.
CGI Service in Los Angeles: What Local Conditions Mean for Your Equipment
Here is something contractors in Santa Monica or Manhattan Beach rarely deal with: in Los Angeles, CGI impact windows are frequently required not for hurricanes but for wildfire ember protection. Hillside and canyon zones like parts of Silver Lake, Echo Park, and the canyons off Roscoe Boulevard fall under strict fire-hardening building codes that mandate ember-resistant vents and non-combustible cladding. CGI’s impact-rated glazing and heavy frames do double duty here. They meet the impact standard, and they hold up against flying embers better than standard windows. If you live in one of those zones, a simple window replacement is not simple at all. It has to be code-compliant, or your insurance company may refuse to renew. We handle that paperwork and inspection coordination as part of the job. Serving the broader Los Angeles service area means we stay current on those code changes.
CGI Models & Products We Service in Los Angeles
We work on the full CGI residential line: the Sentinel Series Impact Windows, the Estate Collection Windows, the Targa Series Impact Windows, and CGI commercial storefront systems. We use genuine CGI replacement parts wherever possible to maintain impact ratings and warranty coverage. For discontinued CGI lines, we source high-quality aftermarket components that meet or exceed original specs. Our approach is simple: we always assess whether a repair will restore the window’s structural and weather performance before recommending replacement. If repair makes sense, we say so. If replacement is the better investment, we give you a written price before any work starts.

FAQs – CGI Construction in Los Angeles
Yes, in mapped hillside and canyon wildfire zones, Los Angeles building codes require ember-resistant openings, and impact-rated glass is one approved path to compliance. The exact requirement depends on your parcel’s Fire Hazard Severity Zone designation. Call (213) 632-5711 and we will check your address against the current maps before recommending anything.
Yes. We remove the old window, reframe the opening as needed, install the new CGI window, and then patch and re-texture the stucco around it as part of our Bathroom Remodeling in Los Angeles. The repair is done to match your existing texture and paint. It does not require tearing off the whole stucco wall.
They hold up well structurally, but the marine layer and sun combination shortens the life of seals and hardware. We recommend west-facing and ocean-facing CGI windows be inspected every two to three years for seal degradation and hardware corrosion. Catching edge fogging early can save you a full glass replacement later.
Not directly. The soft-story retrofit ordinance targets the parking level and the structural frame, not the windows. But if you are already opening walls for a retrofit, that is the most cost-effective time to replace windows, since the crew and scaffolding are already there. For a retrofit in the CGI service in Van Nuys area, we coordinate window work alongside the structural crew.
