CGI Windows & Doors: The San Jose Owner’s Guide
If you have a CGI window or door with a failed part, we stock and install CGI-compatible components across San Jose, with most replacements running $470 – $2,950 installed depending on what failed. Most owners discover the problem the same way: a window that suddenly won’t latch, a door that drags against the frame, or a lock cylinder that spins without catching. CGI builds heavy, hurricane-rated frames and hardware for coastal and high-wind zones, but the moving parts still wear out, especially in San Jose’s dry summers and cool wet winters.
We’re an independent service provider, not a CGI dealer or affiliate. That means we give you a straight price for the part, tell you whether an OEM or quality aftermarket equivalent makes more sense for your model, and install it with a written guarantee. No runaround about “factory-only service.”
Which CGI Models This Applies To
CGI product lines that commonly need parts service in San Jose include the Estate, Estate Collection, Tribute, and Sentinel series. The estate-level windows and doors use heavier extruded aluminum frames with multi-point locking hardware; the Sentinel line leans toward impact-rated entry systems. The best way to identify your exact part is to check the small white or silver sticker on the interior frame edge, typically on the hinge side of a door or the top rail of a window sash. That sticker carries the series code and glass makeup (like “E-35” or similar), and it’s the fastest way for us to match a replacement without guesswork.
On the OEM-versus-aftermarket question: for sash balances, rollers, and weatherstripping, a good aftermarket part gets the job done and usually costs 20 – 40% less than a factory-order part. For multi-point lock actuators and hinge hardware on the heavier estate doors, we recommend OEM. The geometry on those parts is tight, and a slightly-off aftermarket casting is exactly how you end up with a door that latches hard for six months, then won’t latch at all. We won’t sell you aftermarket on a part where it doesn’t belong.
Styles & brands we work with
Signs Your CGI Windows & Doors Is Failing
- Window sash drops when you open it. The block-and-tackle balances or spiral balances inside the side jambs have lost tension. You’ll hear a clunk when the sash falls the last few inches. This is the most common CGI window failure we see in San Jose, especially on west-facing rooms that bake in afternoon sun for years.
- Door drags the threshold or won’t seat into the weatherstrip. The hinges or the threshold insert have worn, or the slab has settled slightly. CGI doors are heavy, and a hinge barrel that’s worn even 1/16 inch reads as a door that sits a quarter-inch low at the latch.
- Multi-point lock turns but the top or bottom shoot bolt doesn’t engage. In CGI’s multi-point systems, the shoot bolts are driven by a gear strip inside the lock rail. A stripped gear or a bent connecting rod means the handle feels like it’s working while the door is only latched at one point.
- Condensation or fog between the panes of the insulated glass. The sealed unit has lost its gas fill and the desiccant in the spacer bar is saturated. That’s a glass unit replacement, not a glass repair, and it’s common on south-facing San Jose exposures after 12 to 18 years.
- Sticky lock cylinder or handles that feel gritty. Fine dust works into the cylinder and wears the tumbler pins. San Jose’s dry season blows a lot of fine particulate, and CGI cylinders have tighter tolerances than average; we can usually clean and re-lubricate, but a frozen cylinder that resists the key is a replacement.
Replacement Cost & What’s Included
Our typical installed ranges in San Jose break down like this:
- Sash balance replacement (single window): $470 – $825 installed, including both balances and the tilt-latch check.
- Roller and hinge replacement on a single door slab: $710 – $1,180 installed.
- Multi-point lock assembly (OEM): $945 – $2,125 installed, depending on door height and whether the handle set gets retired at the same time.
- Insulated glass unit replacement: $1,180 – $2,950 installed, driven by glass size and whether it’s impact-laminated or standard insulated.
Every quote is a written line item: we split the part cost from the labor, tell you if a permit applies (most hardware swaps don’t require one, but some full door replacements in San Jose do), and hand you the completed work guarantee at close. The 365-Day Done Right Promise applies. If the part or the install fails within a year, we return and correct it at no charge. That’s the Garrison Standard, and it’s in writing before any work starts.

AfterDIY or Call Us?
You can safely check a few things yourself: read the frame sticker to get the series code, confirm whether the problem is in the handle, hinge, or sash track, and snap a photo of the failed part next to a tape measure. That photo saves real time when you call. What you should not do is pull apart a multi-point lock rail or remove a heavy CGI sash alone. Those sashes run 40 to 70 pounds and the plastic jamb retainers will crack if they’re released wrong; the lock rail has springs under tension, and the parts are small enough to fire across the room if the wrong clip lets go. We’ve fixed more than one DIY attempt that became a two-hour repair plus a new gear box.
If the part has failed, call (669) 272-2637. We will match it, price it in writing, and install it like we mean it.
FAQs
Block-and-tackle balances on CGI windows typically last 10 to 15 years in San Jose, with south- and west-facing windows failing first because sustained heat ages the internal spring and polymer cord. If one balance in a pair has failed, we replace both so the sash tracks evenly.
Sometimes, but it depends on the part. A sticky lock cylinder can often be cleaned and re-lubricated; a gear strip with a stripped tooth on a multi-point lock cannot. We’ll tell you straight which side your part falls on, and we won’t sell you a replacement if a proper cleaning does the job. Call (669) 272-2637 and we’ll walk through what you’re seeing.
Most single-part replacements, like a pair of sash balances, a lock assembly, or a threshold insert, are done in 60 to 90 minutes on site. An insulated glass unit replacement usually needs one visit to measure and order, then a second visit to install once the factory ships the unit, typically within two to three weeks.
We stock common aftermarket equivalents on the service vehicles: sash balances, rollers, weatherstripping, threshold inserts, and standard handle sets. Series-specific CGI multi-point gear boxes and laminated glass units are ordered per job. We also stock parts for other lines we service, including KraftMaid, Cambria, and Silestone cabinetry and surfaces.
