Why Los Angeles Homeowners Choose CGI Construction
Mason Remodeling Co Los Angeles provides CGI repair in Los Angeles as independent window and door service across the city, handling impact window installation, fogged-glass replacement, hardware repair, and full-frame replacement on Series 300, Classic Series, and Estate Collection products. We’re not an authorized CGI dealer, and we’ll tell you that up front. What we are is a Los Angeles remodeler with hands-on time in these products, a written price before any tool comes off the truck, and a 365-day Done Right Promise on every job. For a free estimate on CGI service, call (213) 632-5711.
CGI impact windows and doors are common in Los Angeles hillside and canyon homes where wind-driven debris and wildfire embers are a real concern. The products are built for Miami-Dade wind loads, which is overkill for most Los Angeles conditions, but that toughness also means they tolerate decades of sun and dry heat better than many vinyl lines. The failure patterns we see here differ from coastal Florida. Los Angeles sun degrades weather stripping and exterior gaskets faster than salt air does in Miami, and we regularly find fogged glass on older CGI units where the seal has given out after 15 or 20 years of intense UV exposure. Our crews have worked on CGI products from the San Fernando Valley to the Palisades, and we understand what these windows need in this climate, including CGI in Van Nuys.
Why Trust Mason Remodeling Co Los Angeles for Your CGI Construction?
Isaac Pruett grew up in the San Fernando Valley and spent his weekends watching his uncle tear out and rebuild just about every surface in a house on Roscoe Boulevard. That’s where the building bug bit. He trained in construction technology at Los Angeles Trade-Technical College downtown, then spent the better part of two decades working as a General Contractor on residential and light commercial jobs across Los Angeles County. Today he runs Mason Remodeling Co Los Angeles with a straightforward philosophy: show up on time, keep the site clean, and never leave a homeowner guessing about what happens next. His wife still teases him that he eyeballs a level line before he’s finished his coffee every morning.
That background matters when you’re trusting a crew with CGI windows that cost thousands of dollars per opening. Our technicians know the difference between a Series 300 impact window and an Estate Collection unit, and they understand how the frame anchoring differs between a wood-framed wall and a stucco-on-block exterior. Every Mason Remodeling technician is background-checked and identity-verified under the Threshold Standard, and you get the technician’s name and photo before the visit, plus a photo ID badge at the door on arrival. The 365-Day Done Right Promise applies to CGI work just like every other project: if the work isn’t right within a year of completion, we make it right at no cost to you. Know who’s coming, know what it costs, know it’s guaranteed – everything else is just noise.

Common CGI Construction Problems We Fix in Los Angeles
CGI windows and doors are well-built, but any product that’s been in a Los Angeles home for a decade or more will show specific failure patterns. Here’s what we see most often:
- Fogging between the glass panes. This is the number one complaint on aging CGI impact windows in Los Angeles. The insulating glass seal fails, moisture gets trapped between the panes, and the window turns foggy or milky. In coastal areas like Playa del Rey and Marina del Rey, the salt-heavy humidity makes seal failure happen faster than inland. The fix is often a new insulated glass unit (IGU) rather than a full window replacement, which keeps costs down and preserves the original frame.
- Roller and track wear on Classic Series sliding glass doors. CGI Classic Series sliders are heavy, and after years of use, the rollers flatten, the track gets packed with grit, and the door starts grinding or binding. Our techs responded to a Los Angeles home where a CGI sliding glass door had become difficult to open. We found the rollers worn and the track misaligned, replaced the roller assemblies, and realigned the track. The door now glides smoothly and the homeowner avoided a full door replacement.
- Fogged or hazy laminated glass on older Estate Collection units. The Estate Collection uses laminated impact glass with an interlayer. Over time, especially on south-facing or west-facing elevations that get the full Los Angeles sun, the interlayer can show evidence of age – slight hazing or optical distortion at the edges. This is cosmetic in most cases and fixable with a new IGU rather than a full frame swap.
- Frame sagging or binding on large fixed windows. We see this on oversized CGI picture windows where the original installation didn’t include proper header support. In older Los Angeles homes, particularly 1920s and 1930s wood-frame construction, the original headers weren’t engineered for the weight of today’s impact-rated glass packages. The frame sags, the sash binds, and the unit locks up tight. This calls for a structural fix, not just a window repair.
- Deteriorated weather stripping and exterior gaskets. Los Angeles doesn’t get much rain, but the UV exposure is relentless. After eight to twelve years, the rubber and foam weather stripping on CGI windows and doors turns brittle, cracks, and loses its seal. You’ll notice drafts, dust intrusion, and water staining along the bottom track. Replacing the weather stripping is straightforward and restores the original performance.
CGI Parts & Our Repair-vs-Replace Approach
We prefer genuine CGI replacement parts – seals, hinges, locks, rollers – because they match the original engineering and preserve whatever warranty may still apply. When an older CGI model is out of production and OEM parts are no longer available, we’ll source high-quality aftermarket glass packs from specialty fabricators we trust. We’re transparent about which path we’re taking and why.
The repair-vs-replace decision comes down to the condition of the frame. If the IGU is fogged but the frame is square, solid, and free of rot or corrosion, a new glass pack gets the window back to like-new performance at a fraction of replacement cost. If the frame is warped, the sash has pulled away from the weather stripping, or multiple panes show seal failure, replacement is usually more cost-effective than patching. We’ll show you the numbers both ways so you can decide with the full picture. Call (213) 632-5711 for an exact quote – estimates are free.
Our CGI Service Process – Step by Step
Every CGI service call follows the same sequence, whether it’s a fogged IGU replacement on a Series 300 window or a full impact window installation on a new addition:
- 1
Written diagnosis. A technician inspects the window or door, identifies the exact failure, and documents it with photos and measurements. You get a written price for the repair or replacement before any work begins – never a verbal estimate that grows later.
- 2
Parts ordering and scheduling. For genuine CGI parts, we place the order immediately and give you a real timeline. For glass packs, we measure precisely and order from our glass fabricator. No deposits are collected on a handshake – the written quote is the agreement.
- 3
Repair or installation. The technician arrives in a clean marked uniform, shows a photo ID badge at the door, and gets to work. For frame replacements in older Los Angeles homes, we inspect and correct header support or weathered framing before the new unit goes in.
- 4
Testing and adjustment. The window or door is cycled open and closed, the seals are checked, and the locking points are verified. On sliders, the track is cleaned and realigned. On impact windows, we confirm the anchoring is secure and the unit sits plumb and level.
- 5
Written warranty delivery. Your coverage terms are stated plainly – what’s covered, what’s excluded, and for how long: 365 days from the completion date. If anything we touched fails in that window, we come back at no charge.

AfterCGI Products We Service & Install in Los Angeles
Our crews work on the full CGI lineup most commonly found in Los Angeles homes: the Series 300 impact windows, the Classic Series sliding glass doors, and the Estate Collection windows. Series 300 units are the workhorse line, found in everything from 1960s ranch homes in the Valley to newer builds in West Adams and CGI service in Beverly Hills. Classic Series sliders show up on a lot of Los Angeles mid-century homes where a large glass opening faces a backyard or pool. Estate Collection windows are the premium tier, usually installed in hillside and canyon homes where the buyer wanted the best available impact rating.
We stock common CGI-compatible seals, rollers, and hardware locally for faster turnaround, and we can source OEM parts or custom glass packs on most models within a week or two depending on availability. We also handle full impact window installation for new construction and remodels, including the structural anchoring details that Los Angeles hillside and seismic codes require.
We Also Service These Brands
CGI isn’t the only brand we work with. Mason Remodeling Co Los Angeles crews are experienced with KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone surfaces, and Kohler, Moen, Toto, and Grohe fixtures. We’re a multi-brand remodeling company, which means we’re not tied to any single manufacturer’s product line when a broader solution fits the home better.
FAQs – CGI Construction Service in Los Angeles
No. We are an independent CGI service provider, not an authorized dealer or factory warranty station. That means we don’t perform warranty-covered repairs on CGI’s behalf, but it also means we’re free to recommend whatever solution actually fits your home and budget – including aftermarket glass packs when OEM parts are unavailable. Our 365-Day Done Right Promise covers our workmanship regardless of manufacturer authorization.
Yes, whenever they’re available and appropriate. For seals, hinges, locks, and roller assemblies, we order genuine CGI parts because they match the original tolerances and materials. For older models where the factory has discontinued certain components, we source high-quality aftermarket glass packs from vetted fabricators. We’ll always tell you which parts we’re using before the work is done.
Yes, and we do it regularly. We see a lot of Los Angeles homes where the original CGI installation was done years ago by a builder or a different contractor. The beauty of working with an independent service provider is that we don’t care who installed the window originally. We care about what’s wrong with it now and how to fix it right. Call (213) 632-5711 and we’ll schedule a diagnosis.
Yes. Fogging between the panes is caused by a failed seal in the insulated glass unit, not by a failed frame. In most cases, we can replace just the IGU while keeping the original CGI frame intact. You get clear glass again without paying for a full window replacement. The exception is when the frame itself has been damaged or has shifted – then a full replacement makes more sense. We’ll show you both options with written pricing.
Look for three things: multiple fogged panes in the same window or across several windows, visible frame warping or sagging (especially on wide fixed units), and water staining along the sill or inside the wall below the window. If the frame is square and solid, a glass pack replacement is usually the right call. If the frame is compromised, full replacement is more cost-effective than repeated repairs. We’ll give you a straight answer either way.
Yes. Coastal Los Angeles building codes treat wind exposure differently depending on proximity to the ocean and the structure’s height. CGI impact windows carry Miami-Dade and Florida Building Code approvals, which meet or exceed the wind load requirements for most Los Angeles coastal zones. Our techs understand the anchoring schedules and flashing details those applications call for, and we pull permits where the local jurisdiction requires it. If you’re within a coastal overlay, mention it when you call – we’ll confirm the code path that applies to your property.
Yes. Every CGI repair and installation from Mason Remodeling Co Los Angeles carries the 365-Day Done Right Promise. If the work isn’t right within one year of the completion date, we return and make it right at no cost to you. Coverage terms are stated in writing before we start, so there’s no ambiguity about what’s included. If a repair or installation fails, the second visit is free – no charge, no dispute process.
CGI work spans a wide range depending on whether you’re repairing a fogged window or installing new impact windows throughout the house. Here are the price ranges we use for Los Angeles projects:
| Service | Typical Price Range |
|---|---|
| Impact Window Installation | $9,440 – $29,500 |
| Window Replacement | $5,310 – $17,700 |
| Roof Replacement | $9,440 – $23,600 |

These are realistic Los Angeles market ranges, not online estimates pulled from a national database. Your exact price depends on the number of windows, the specific CGI product line, the condition of the existing framing, and whether permits are required for your location. Call (213) 632-5711 for a free estimate with a written price before any work starts.
