CGI Windows & Doors: The San Antonio Owner’s Guide
CGI windows and doors are built to take a beating from hurricanes and coastal weather, but even a brand known for impact glass has parts that wear out: rollers, balances, seals, latches, and thresholds. In San Antonio, we stock and install CGI-compatible replacement parts for most window and door series, and typical in-place parts repair runs $400 to $1,800 depending on what failed and how many units are involved. Most owners discover the problem the same way: a window that suddenly takes both hands to open, a door that scrapes the frame, or a latch that no longer catches cleanly. You’ll find the specific fix below, with honest pricing and a phone number that a live person answers.
Which CGI Models This Applies To
CGI’s catalog spans several lines, and parts are not always interchangeable between them. The most common series we see in San Antonio homes are the Estate Collection, Targa, Clarity, and the vinyl impact lines sold through builders. The fastest way to identify your exact window or door is to look for the AAMA certification sticker on the frame or sash, usually gold or silver, which lists the series name, the manufacturing date, and a serial number. If the sticker is gone, which happens often after years of Texas sun, we can still match the part by measuring the sash thickness, the glass package depth, and the hardware mounting hole pattern. For CGI specifically, we default to OEM parts when the failed piece affects structural integrity: a roller, a balance assembly, or a locking mechanism. For trim pieces, screens, and weatherstripping, quality aftermarket equivalents often cost 30 to 40 percent less and perform the same, and we’ll tell you which route we recommend for your exact unit before any work is approved. One compatibility gotcha: CGI’s impact-rated sash rollers have a narrower housing than standard residential rollers, so a big-box replacement rarely seats correctly and causes the window to bind again within months.

Signs Your CGI Windows & Doors Is Failing
- Window takes real effort to lift or close. On single-hung and horizontal roller CGI units, the nylon rollers wear flat over thousands of open-and-close cycles in San Antonio’s dust-heavy air. Once the wheel stops rolling, the sash drags on the track and wears the aluminum instead.
- Sash drops a few inches on its own. This is a balance failure. CGI’s heavy impact glass needs a specific block-and-tackle or constant-force balance rating, and when it weakens, the window cannot hold position. It’s a part that should be replaced in pairs, not one side only.
- Door scrapes or catches at the bottom. Rollers on CGI sliding doors carry a lot of weight, and when they collapse or seize, the panel grinds along the track. Left alone, the track itself gets scored, and that is a more expensive fix than releasing the adjustment and swapping the rollers.
- Latch or lock turns but won’t engage. On CGI’s multi-point locking doors, the gearbox can wear and leave the door feeling closed but not actually secured. The tell is a handle that turns with no resistance, and a door that can be pushed open without touching the lock.
- Condensation or haze between the glass panes. This is a failed seal, and on CGI’s impact glass the fix is often a full sash or full unit replacement rather than a glass-only repair. It is the one sign that usually means the part is past saving and the conversation turns to replacement.

AfterReplacement Cost & What’s Included
For most CGI parts repair in San Antonio, budget $400 to $1,800 depending on the part and how many windows or doors are affected. A single horizontal slider’s roller pair typically runs $400 to $700 installed. A balance replacement on a large single-hung window runs $300 to $600 per window. A sliding door roller and track cleanup usually lands between $500 and $900. The higher end, $1,200 to $1,800, is for multi-point locking gearboxes or multiple units done at once. We write the line-item price before any work starts: the part number, the part cost, the labor, and the time window. That written price is what you pay. The workmanship on any CGI part we replace carries our 365-Day Done Right Promise. If the window bind or door drag comes back within a year, we make it right at no charge.
DIY or Call Us?
There are honest checks you can do before calling: on sliding windows and doors, clear the lower track of sand and pet hair and see if the motion improves; on a sticking window, check for a bent frame or a nail from a screen installation poking into the track. Those are safe fixes with no trouble. What we ask you not to do is disassemble the sash or the balance system on an impact-rated CGI unit. The glass package is heavy, the balances are under tension, and a dropped sash can take a window out of the frame or hurt the person holding it. That is not a caution we state lightly; it is the reason we carry the right rollers and balances on the truck when we pull up. If the part is beyond a simple check, call (432) 233-0976 and we will come take a look, name the part, and hand you a written price before anything is taken apart.
FAQs

Most CGI rollers, balances, and latches last 10 to 15 years in San Antonio’s heat and dust, with sliding door rollers often failing first due to the weight they carry and how much track grime builds up. Impact glass itself carries CGI’s warranty for much longer, but the moving hardware is a wear item.
Some parts, like a track that needs cleaning or a latch that only needs adjusting, can be brought back to spec without new hardware. But for rollers, balances, and seals that have physically failed, repair is not honest work; we replace those with the correct CGI-compatible part rather than band-aid it and come back in six months. Call (432) 233-0976 if you are unsure which camp your window falls into.
A single roller or balance swap is usually done in under an hour. A sliding door that needs new rollers, a track clean, and a locking adjustment might take two hours. We’ll tell you the window before we start, and the written price will not change because the work took longer than we expected.
We keep the most common CGI rollers, balances, and locking hardware on the truck for San Antonio service calls. For an unusual series or an older discontinued unit, we source OEM or matched aftermarket parts from our suppliers and have the part in hand before scheduling the install so you are not living with a stuck window while we wait on a shipment.
