CGI Windows & Doors Nationwide

CGI Windows & Doors: The Los Angeles Owner’s Guide

We stock and install CGI-compatible windows and doors across Los Angeles, with typical installed replacement costs running $5,310-$17,700 depending on size, series, and whether the opening needs reframing. Most standard sash, hardware, and frame parts are available same-day through our supplier network in the basin. Los Angeles homeowners usually discover a CGI part has failed when a window won’t stay open, the lock doesn’t catch, or they feel a draft along the sill that wasn’t there last season.

Which CGI Models This Applies To

CGI builds three core residential lines you’ll see in Los Angeles homes: the Estate Series (aluminum impact), the Sentinel Series (vinyl impact), and the commercial-grade Targa line. The part you need depends on which generation you own. Estate Series units manufactured before 2018 used a two-point locking system with a 7/8-inch throw; post-2018 models switched to a 1-inch throw with a wider keeper plate. That half-inch difference means the wrong lock won’t seat, and we’ve seen it happen when a homeowner orders by photo alone.

To identify your part, check the etched code in the glass corner (format: CGI-YY-MO-SER) and measure the visible glass dimensions, not the frame. For hardware, the stamped part number sits on the lock face or hinge barrel. We carry both OEM CGI hardware and quality equivalents from Truth and Caldwell that match the spec at a lower unit cost. The aftermarket route makes sense for discontinued Estate 200-series parts, but for impact-rated assemblies we recommend staying OEM to preserve the Miami-Dade NOA certification that underwrites your wind coverage.

Signs Your CGI Windows & Doors Is Failing

• The sash drifts or won’t hold position. This usually means the balance system has lost tension. In Los Angeles, the dry heat cycles of Pasadena and the San Fernando Valley accelerate coil spring fatigue compared to coastal climates.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed. Once argon escapes and desiccant saturates, the pane is done; no repair brings the R-value back.
• Lock engages but the sash still shifts. The keeper is worn or the frame has settled. In older Los Angeles homes with raised foundations, we see this often on south-facing elevations where thermal expansion works the fasteners loose.
• Difficulty raising or lowering the sash. Debris in the track, worn rollers, or a warped vinyl frame. Coastal properties from Marina del Rey to San Pedro get salt buildup that pits aluminum track inserts.
• Air leakage at the meeting rail or sill. Compression weatherstrip has hardened. CGI’s bulb-style gaskets last roughly 8-12 years in Los Angeles sun before they crack; replacement is straightforward but the part must match the groove dimension exactly.

Replacement Cost & What’s Included

Window replacement in Los Angeles runs $5,310-$17,700 installed, with most CGI-specific jobs falling in the $7,000-$12,000 range for a multi-opening project. Single-part repairs are priced differently: a lock or balance replacement typically runs $180-$340 in labor plus parts, while an IGU swap runs $340-$620 per pane depending on low-E coating and tempering.

What drives the range: accessibility (second-story requires scaffolding or pump jack), whether the opening is out of square, and if the interior trim needs replacement. Our quote breaks out parts, labor, and any reframing separately. Under Clause 1 of the Haven Standard, you get that written price before anyone picks up a tool. The 365-Day Done Right Promise covers the installation, and we register the CGI warranty on your behalf so there’s no paperwork gap.

DIY or Call Us?

There’s a clear line between what you can check and what you should handle. A homeowner can clean the track, verify the lock engages fully, and confirm the weep holes (the small drainage slots in the sill) aren’t clogged with stucco or paint. What we don’t recommend: removing an impact-rated sash without understanding the load path, or attempting to reset a warped frame. CGI’s impact assemblies are engineered as a system; compromise one component and the NOA certification is void.

If you’re unsure which series you have or whether the part is still manufactured, call us. We’ll bring the common hardware to your door, measure on-site, and if it’s not the right fit, we don’t charge for the trip. If it’s not written down, it didn’t happen.
