CGI Windows & Doors: The Woodland Hills Owner’s Guide
Replacing a failed CGI window or door part in Woodland Hills typically runs $400 – $1,800 for a repair and $4,500 – $25,000 for full impact window replacement, depending on what failed and how accessible it is. We stock the most common CGI-compatible hardware on our trucks, so most single-part fixes happen the same day we arrive. Most Woodland Hills homeowners discover the problem the hard way: a window that suddenly won’t lock, a door that drags the frame, or a roller that grinds metal-on-metal after three or four San Fernando Valley summers of heat and dust.
Sawyer Remodel Woodland Hills is an independent service provider. We’re not affiliated with CGI, but we’ve worked on their products for years, and we carry the parts that actually fail on CGI windows and doors in this climate.
Which CGI Models This Applies To

CGI’s product lines share a lot of hardware DNA, but there are compatibility gotchas you need to know before ordering anything online. The biggest one we see in Woodland Hills: rollers and hinges are not universal across CGI’s impact-rated versus non-impact series. An impact window with the thicker laminated glass uses a heavier-duty roller assembly than the standard unit, and putting standard rollers on impact glass means a sash that sags within six months.
To identify your specific CGI part, open the frame and look for a sticker on the inner track or the head of the sash. It’ll have a series code, a manufacturing date, and sometimes the Miami-Dade or AAMA certification number. If the sticker is gone, measure the visible glass and the frame thickness. Impact glass runs roughly 7/16-inch to 9/16-inch thick on CGI units, versus 3/4-inch to 1-inch for standard insulated glass. That measurement alone tells you which hardware family you need.
OEM parts cost more, often 20% to 40% more than quality aftermarket equivalents. For high-wear items like rollers, latches, and weatherstripping, we typically recommend aftermarket parts that match or beat the OEM spec. For anything structural or related to the impact rating, OEM is the only call. The impact certification is attached to the assembly as a system, and substituting non-certified parts can void the product approval.

Signs Your CGI Windows & Doors Is Failing
- Sash won’t lock or the lock requires force. The multi-point lock mechanism on CGI doors and windows can wear synchronize-springs over time, especially with the fine dust that settles into Woodland Hills homes from the hills. If you’re forcing it, the lock bar is already wearing down its strike points.
- Grinding or scraping sound when opening or closing. Almost always the roller assembly. CGI rollers have nylon wheels that flatten over time, then the metal housing rides directly on the track. Once you hear metal-on-metal, the track is being scored and the repair cost climbs.
- Water stains at the bottom corner of the frame. The weeping system on CGI impact windows is designed to route moisture out through small slots in the sill. When those slots clog with dust and debris, water sits in the frame and works its way inside. In Woodland Hills, the culprit is usually a mix of fine particulate from the 101 corridor and yard debris.
- Condensation or fogging between the panes. That’s a seal failure. The desiccant inside the insulated glass unit is saturated and the window has lost its insulating value. On CGI units, the glass assembly is replaceable without pulling the whole frame.
- Door drags or won’t clear the threshold. Impact doors are heavy. When the bottom roller adjustment drifts or the hinges wear, the weight shifts and the door starts dragging. Left alone, it eventually damages the threshold, the weatherstripping, and sometimes the frame corner welds.

AfterReplacement Cost & What’s Included

Installed CGI-compatible part replacement in Woodland Hills runs $400 – $1,800 for most single-part fixes: rollers, locks, hinges, weatherstripping, balancers, and threshold rebuilds. Full impact window replacement runs $4,500 – $15,000 depending on size, elevation, and how many units are involved. What drives the range on a single-part repair is access. A first-floor slider with easy reach is fast. A third-floor window with a steep hillside drop behind it takes longer, and the price reflects that.
Every repair includes the part, the labor, and a written price before we start. No change orders, no surprise add-ons. The workmanship carries our 365-Day Done Right Promise: if something we touched fails within a year, we’re back on it at no charge.
DIY or Call Us?
Some things you can check safely: visible wear on the track, debris clogging the weep slots, a latch that’s visibly bent or loose. Cleaning a CGI track with a soft brush and clearing the weep holes with a small pick or can of compressed air is fine. It won’t fix a failed part, but it’ll tell you if the track is the problem or the hardware is.
Where DIY goes wrong is trying to swap rollers, balancers, or lock mechanisms on an impact-rated sash. Windows using spec’d CGI hardware rely on evenly distributed tension. If you release that tension without knowing the mechanism, the sash can drop, the spring can release, and you’re looking at a frame repair that costs more than the original part would have. We’ve seen it in Woodland Hills more than once. If the part requires pulling the sash, call (341) 217-2776 and let us do it right.
FAQs

CGI impact windows in the Woodland Hills climate typically last 20 to 30 years on the frame, with hardware replacements expected every 10 to 15 years. The sun and heat load on the west side of the Valley ages rollers, seals, and weatherstripping faster than the frame itself. If your units are from the 2000s, you’re likely due for the first round of hardware. Call (341) 217-2776 and we’ll tell you if it’s a repair or a replacement situation.
Most failed CGI parts can be repaired without replacing the window. Rollers, locks, hinges, balancers, weatherstripping, and even the glass unit itself are all replaceable components. The only time replacement wins is when the frame is compromised: cracked corner welds, significant rot in a wood-frame unit, or a failed impact certification. Get an honest assessment by calling (341) 217-2776. Estimates are free.
A single-part replacement usually takes an hour or two once we’re on site. A full glass-unit swap takes half a day. Anyone quoting a multi-day timeline for a roller or lock replacement doesn’t have the right part with them. We stock the high-failure CGI parts on our trucks, so most Woodland Hills jobs are one visit.
We keep the most common CGI-compatible parts in stock: rollers in both impact and non-impact weights, multi-point lock assemblies, hinge sets, balancers, and weatherstripping profiles. Oddball sizes and older series parts may need ordering, which adds a few days. The quickest way to know if yours is on the truck is to call (341) 217-2776 and describe the sticker or measurements.
If your CGI window or door has a failed part, don’t nurse it along. A dragging door gets worse. A forced lock breaks. Call (341) 217-2776 or reach out online and we’ll get it diagnosed, priced, and fixed. The work tells you everything. We just make sure it tells the right story.
