Why Pasadena Homeowners Choose CGI Construction
We’re an independent CGI in Pasadena service provider, not a manufacturer-authorized dealer, and we repair, service, and install CGI windows and doors across the city’s Craftsman and Spanish Colonial homes. Our team has worked on enough CGI Estate Collection and 800 Series products to know exactly how they behave in Pasadena’s dry heat and winter downpours. If you need a warped casement fixed, a fogged picture window assessed, or a Targa patio door that rolls like it did on day one, call (626) 714-2992 for a free estimate.
Why Trust Elmstead Remodeling Pasadena for Your CGI Construction?

CGI products are engineered for impact resistance, but they’re only as good as the hands that install them. Graham Stein, General Contractor and owner of Elmstead Remodeling Pasadena, grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending nearly two decades on projects across the San Gabriel Valley. He and his crew have worked steadily through Bungalow Heaven, where older Craftsman frames demand a slower hand and a willingness to shim, measure twice, and flash properly the first time. Graham puts the written scope and line-item price in front of a homeowner before a single drop cloth goes down, because a family deserves to understand exactly what will happen to their house before it happens.
That same discipline applies to CGI work. We source genuine CGI replacement hardware, rollers, and weatherstripping through independent distributors so the fit and finish match the original. We’re not authorized by CGI, and we’ll tell you that straight. What we bring is field experience with their product lines, a warranty-safe approach to repairs, and the same Cedarwell Care Promise that governs every Elmstead job: shoe covers and drop cloths inside the house, a written price before any work starts, and a photo of the clean-up before the crew leaves.

Common CGI Construction Problems We Fix in Pasadena
CGI windows and doors earn their reputation in hurricane zones, but Pasadena’s hot, dry summers and cool, wet winters create their own set of failure patterns. Here are the issues we see most often:
- Warped or hard-to-operate sashes on CGI 800 Series casements. The operator gears strip and the hinge tracks wear after years of thermal cycling. Homeowners tell us the crank turns but the sash doesn’t move, or the window won’t close without lifting the frame. We replace the gears and realign the hinges rather than condemning the whole unit.
- Fogged insulated glass on large fixed picture windows. Western exposure in Pasadena bakes the sealant until it fails, and moisture gets trapped between the panes. A fogged Estate Collection picture window often needs a new glass unit, not a full window replacement, unless the frame itself has corroded.
- Targa Series patio door rollers that bind or jump the track. The roller bearings wear down, the door gets heavy, and someone gives it a good yank. Then it’s off the track entirely. We replace the rollers with genuine CGI parts and adjust the track alignment so the door glides again.
- Leaks at the sill corners during winter storms. Improperly flashed installations allow water to pool at the sill corners and find its way inside. We trace the leak to the flashing or the pan condition, not just the glass, and fix the actual source.
- Faded or cracked weatherstripping on Estate French doors. Pasadena’s summer heat dries out the gaskets, which compromises the seal and lets dust and drafts through. We replace the weatherstripping with OEM-spec material so the door seals tight again.
CGI Parts & Our Repair-vs-Replace Approach

We stock common CGI replacement parts locally for faster turnaround: roller assemblies for Targa hinged doors, operator gears and hinge tracks for 800 Series casements, and weatherstripping profiles that match the original extrusion. When the frame itself is corroded, the glass unit is beyond reasonable cost to replace, or the window was installed with failed flashing that has already damaged the rough opening, we’ll tell you straight and quote a full window or door replacement using current CGI models.
We don’t push replacement when a repair will hold. A stripped operator gear is a $200 fix, not a $2,000 window. But we also won’t patch a frame that’s rusting through. The written price you see on paper is the price you pay at the end, no footnotes. Call (626) 714-2992 and we’ll assess your CGI products honestly.
Our CGI Service Process – Step by Step
- 1
Diagnosis. We inspect the sash, frame, hardware, and flashing. We’ll show you what we found and explain which parts are worn and why. A photo of the failed component goes in your file.
- 2
Repair or install. We replace the failed hardware or glass with genuine CGI parts, or we remove and reinstall the unit with proper flashing and pan conditions if that’s what the job requires. Drop cloths go down, shoe covers go on, and we protect the surrounding floors and surfaces.
- 3
Test. We operate every window and door through its full range of motion. We check the seal, the balance, and the drainage. If it doesn’t feel right, we adjust it before we call the job done.
- 4
Warranty. Every completed project carries the 365-Day Done Right Promise. If it’s not done right, we make it right. That’s written into the scope, not said in passing.

FAQs – CGI Construction Service in Pasadena

Can you repair a warped CGI 800 Series casement sash without replacing the whole window?
Yes. In most cases, a hard-to-operate casement is caused by stripped operator gears or worn hinge tracks, not a warped sash. We replace the hardware with genuine CGI parts and realign the hinges. A full window replacement is only needed when the frame itself is damaged or the sash has actually warped beyond adjustment. Call (626) 714-2992 and we’ll diagnose it for you.
The glass in my CGI Estate picture window is fogging. Do I need a full window replacement?
Not necessarily. Fogging between the panes means the insulated glass seal has failed. The fix is often a new glass unit, not a whole new window, unless the frame is corroded or the sealing surfaces are compromised. We’ll inspect the condition of the frame before we make a call. Call (626) 714-2992 for a straight answer.
Do you use genuine CGI parts for patio door roller repairs?
Yes. We source genuine CGI roller assemblies, weatherstripping, and hardware through independent distributors. We do this because the fit and the finish match the original, and it keeps your product performing the way it was engineered to. When the original part is discontinued, we’ll tell you and offer the closest compatible option with a written explanation.
Why is my CGI window leaking at the bottom corner during Pasadena’s winter storms?
That leak is usually a flashing problem, not a glass problem. Improperly flashed installations allow water to enter at the sill corners during Pasadena’s winter downpours. We remove the interior trim if needed, trace the water path, and repair the flashing or pan condition at the source. Caulking the glass won’t fix it. Call (626) 714-2992 for an assessment.
Can you service CGI windows that were part of a recent remodel by another contractor?
Yes. We regularly step in after other contractors have installed CGI products incorrectly or left a leaking flashing detail. We’ll inspect the installation, correct any flashing or weatherproofing issues, and repair any hardware that was damaged in the process. The 365-Day Done Right Promise applies to our work regardless of who did the original install.
