CGI Windows & Doors: The Woodland Hills Owner's Guide
If you have a CGI window or door with a failed part, you need a straight answer about the part, the price, and who can install it. We stock and install CGI-compatible replacement parts in Woodland Hills, with most window parts running $180 – $650 installed and door hardware typically between $120 – $480 depending on the series and part. Same-week appointment slots are available for most replacements, and we carry a stocked inventory of common CGI series parts on our trucks so we can often diagnose and swap the part in a single visit.
The way most homeowners discover a failed part is quiet, not dramatic. A window that suddenly takes two hands to slide. A door handle that spins without catching. A lock that won't throw the bolt. A corner that leaks for the first time in fifteen years. These failures don't usually announce themselves with a crash. They just slowly stop working, and one morning you realize you've been working around it for weeks. We've repaired enough CGI products across Woodland Hills to know which parts fail first and which ones are worth replacing proactively.
Which CGI Models This Applies To
CGI manufactures windows and doors across several distinct product lines, and the part you need depends on which series you have. The most common we see in Woodland Hills homes are the Estate Collection (impact-rated windows and French doors), the Targa Series (horizontal roller windows), the Estate Single Hung, and the CGI sliding glass door lines that many properties near Warner Center and Walnut Acres installed in the 2000s. Each series uses different balances, rollers, locking hardware, and weatherstripping.
Here's the compatibility gotcha most homeowners don't know: CGI parts are not universally interchangeable across series. A Targa roller assembly will not fit an Estate slider, and the lock sets differ between the Estate hinged door and the CGI sliding door lines. You can identify your series from the small etched label in the corner of the glass, usually bottom-left on windows and top-edge of door panels, containing the model code and a serial number. Or call us with a photo of the label and we'll identify the part before we schedule.
For OEM versus aftermarket replacement parts, our position is simple: we default to OEM CGI parts whenever they're available, because the hinge geometry, lock tolerances, and weatherstripping profiles are engineered to the exact aluminum frame dimensions of your specific window. Quality aftermarket alternatives exist for common parts like rollers and handles, and we stock some of those where the trade consensus is that they last just as long. We will always tell you which option we're quoting and why.

Signs Your CGI Windows & Doors Is Failing
These five symptoms account for the overwhelming majority of CGI parts work we do in Woodland Hills:
- Stiff or grinding slider operation. The roller assemblies in CGI Targa and Estate sliding windows wear flat over time, especially when Santa Ana winds blow grit into the track. In most Woodland Hills neighborhoods, rollers last 10 – 15 years before they flatten into ovals.
- Handle spins freely without engaging. This is almost always a stripped or broken lock/handle mechanism inside the multipoint locking system on a hinged door. The handle itself isn't the failure; the connecting spindle inside the gearbox is. You need the full handleset, not just a handle.
- Window won't stay open. The block-and-tackle balances or constant-force springs inside the jamb have lost tension, which happens faster in homes exposed to direct afternoon sun, particularly on west-facing elevations across the Santa Monica Mountains foothills.
- Draft or water streak at the corner. Weatherstripping compresses and hardens with age, especially in Woodland Hills' dry summer heat cycles. Once the wool pile or vinyl seal loses its compression, that corner becomes a leak point.
- Bolt won't throw on a French door. The multipoint keeps have settled out of alignment, or the gearbox has internal wear. It's rarely the bolt itself. More often it's the connecting rod or keeper alignment that's drifted.
Replacement Cost & What's Included
Here's what you're looking at for installed replacement pricing on common CGI parts in Woodland Hills:
- Sliding window roller assembly replacement: $180 – $340 per panel, including removal, track cleaning, new rollers, and reinstallation.
- Window balance replacement (single or double): $220 – $450 per window, depending on access and whether the sash needs to be disassembled.
- Door handleset and multipoint lock replacement: $280 – $650, depending on whether it's a single-point or full multipoint hardware set.
- Weatherstripping replacement on a hinged door: $150 – $380 per door, including full perimeter replacement and corner seals.
- Full door panel or window sash replacement: $900 – $2,800, depending on the series and glass package.
These are installed prices, meaning the part, the labor, and the cleanup are all in the number. What drives the range is part availability (some CGI series have longer lead times from the factory), access (second-story windows add scaffolding time), and whether the frame itself needs realignment. We deliver a written price before any work starts, so the number you approve is the number you pay.
All of our parts work in Woodland Hills carries a 365-Day Done Right Promise: if the part fails or the installation has any issue within a year, we come back and make it right at no cost to you.

If you have a stiff sliding window, clean the track with a dry brush and check for gravel or debris first. That costs nothing and occasionally solves the problem. If the window is still stiff after a clean track, the rollers are done and no amount of lubricant will bring them back. Roller replacement requires removing the sash, which is heavy glass and aluminum, and the work needs to be done carefully to avoid damaging the frame.
For door hardware and balance systems, we recommend calling us. These parts are under spring tension, and a window balance that's loaded can release quickly if it's handled wrong. You don't need someone on a ladder with a surprise on their hands. The honest answer on most CGI repairs is that the part costs more than the labor, and doing it wrong means paying twice.
If you're in Woodland Hills and dealing with a window that won't cooperate, call (831) 290-6866. We'll identify the part from a photo, give you a written price before the visit, and send a background-checked, uniformed technician whose name and photo you'll have before they ring the bell.
FAQs
How long do CGI windows and door parts last in Woodland Hills?
Most CGI window and door components in Woodland Hills last 10 – 20 years. Rollers and balances tend to fail first, typically around the 12 – 15 year mark, with west-facing elevations wearing faster due to afternoon sun exposure. Lock hardware often outlasts the moving hardware by several years, but once the gearbox starts slipping, it needs full replacement. Call (831) 290-6866 if you're not sure whether your part is at end-of-life or just needs a quick adjustment.
Can a failed CGI part be repaired instead of replaced?
For most failed parts like rollers, balances, and lock gearboxes, replacement is the only reliable fix because these components aren't designed to be serviced. You can't re-tension a constant-force balance or rebuild a worn multipoint gearbox. We always try the lighter fix first when one exists, cleaning and realigning before quoting a full replacement, but the honest truth on most of these parts is that they're wear items and replacement is the repair. Call us at (831) 290-6866 for a straight answer on your specific part.
How long does a CGI parts replacement take?
Most common replacements like rollers, balances, handlesets, and weatherstripping take 1 – 2 hours per unit in Woodland Hills. A single window roller swap is usually done inside an hour. Full door panel or sash replacements take longer because the new part has to be ordered, which adds 2 – 6 weeks depending on the series. We can diagnose during the first visit and give you the timeline in writing.
Do you stock CGI parts?
We stock the most common parts for the CGI series we see most often in Woodland Hills: Targa rollers, Estate window balances, hinged door handlesets, and sliding door roller assemblies. For less common parts, we order directly and keep you informed of the lead time. If you're not sure what series you have, just call us with a photo of the etched label on your window or door and we'll identify it.
