Why San Antonio Homeowners Choose CGI Windows & Doors
Juniper Windows San Antonio provides independent San Antonio Cgi service for windows and doors repair, installation, and maintenance across San Antonio and surrounding areas – we’re not a CGI dealer pushing new inventory, which means every diagnosis starts with your existing product and whether it’s worth saving. Our crews have worked on CGI’s welded-frame and impact-rated lines since the early 2000s, so we know the hardware, the glazing, and the failure points better than most. If your CGI window is fogged, sticking, or leaking air, call us at (903) 488-7019 and we’ll tell you straight whether it’s a repair or a replacement – before any work starts, in writing.
CGI earned its reputation in coastal Florida for impact-rated products built to take a hurricane. San Antonio doesn’t get hurricanes, but we do get hail, sudden downpours, and UV that punishes cheap frames. That’s why CGI’s welded-frame construction and laminated glass options show up in homes here – and why they need a service crew that understands the product line, not a handyman guessing at it. We’re independent, fully insured, and we’ve never had a CGI job we couldn’t diagnose honestly.
Why Trust Juniper Windows San Antonio for Your CGI Windows & Doors?
Sean Mackey, our owner, grew up in Los Angeles and learned the trade fundamentals at Los Angeles Trade-Technical College before spending years on residential and light commercial window and door installations across Southern California. He’s been serving San Antonio homeowners with his crew for well over a decade now, and that track record includes plenty of CGI product – Sentinel, Classic 2100, Estate Collection, Targa. You don’t spend that many years pulling CGI sashes and resealing glazing without learning which repairs actually hold up and which ones just buy time.
Our technicians are background-checked and uniformed, and they arrive with a written price for the work before anything gets touched. For CGI specifically, that matters: these aren’t generic builder windows. The welded frames, the proprietary balance hardware, the impact glazing – every component has a spec, and guesswork creates problems. We use genuine CGI replacement parts when they’re available, and when they’re not, we tell you that upfront and explain the aftermarket alternative, including whether it meets or exceeds the original spec. No mystery parts, no “trust me.”
And because every Juniper job falls under the Relay Visibility Guarantee, you get a live arrival time you can track, before-and-after photos, and a digital invoice. The 365-Day Done Right Promise covers our work for a full year, parts and labor, in writing. If a repair fails, we come back free – no charge, no argument. That’s the whole point: we fix CGI products the way we’d want our own fixed.
Common CGI Windows & Doors Problems We Fix in San Antonio
San Antonio’s climate – intense heat, high UV, humidity, sudden downpours, and the occasional hailstorm – stresses window and door components in specific, predictable ways for CGI Windows & Doors in Fair Oaks Ranch, TX and throughout the region. Here’s what we see most often on CGI product in this area:
- Fogging in Sentinel insulated units. The Sentinel line uses dual-pane insulated glass, and when the seal at the spacer fails, moisture works its way between the panes. You’ll see condensation that won’t wipe off. In San Antonio, the heat accelerates seal deterioration, and once the desiccant inside the spacer is saturated, the only real fix is replacing the IGU – we do that with OEM-spec glazing that matches the original thermal performance.
- Sticking or jamming sashes on Classic 2100 single hungs. The Classic 2100 series uses block-and-tackle balance systems, and after years of San Antonio dust, pollen, and occasional construction debris, the tracks get gritty and the balance shoes wear. You’ll feel the sash bind halfway up or refuse to stay raised. We clean the tracks, replace the balance shoes with OEM-spec parts, and re-set the tilt latches so the window works smoothly again.
- Warped or hard-to-close panels on Estate Collection 3-lite sliders. San Antonio sits on expansive clay soils that shift with moisture. That movement transfers through the frame, and a three-lite slider door takes the brunt of it. The result is a panel that binds at the top or bottom, won’t latch properly, or leaves a gap at the strike. Fixing this properly sometimes means adjusting the rollers, re-shimming the frame, or in advanced cases, resetting panels – not just lubing the track and hoping.
- Weatherstripping compression set on Targa casements. Targa casement windows seal with compression weatherstripping, and after years of San Antonio heat, that weatherstripping loses its memory – it stays compressed and doesn’t rebound. You’ll notice air leaks around the sash edges, especially during winter cold snaps. We replace the weatherstripping with OEM-spec material and adjust the sash so it seats evenly against the frame.
- Failed multi-point lock hardware on impact-rated doors. CGI’s impact-rated doors use multi-point locking systems for structural integrity. When one point fails, the door still locks at the deadbolt, but the top and bottom don’t engage, which compromises the seal and the security. We diagnose whether it’s a misaligned keep, a bent linkage, or a worn gearbox, and we replace only what’s actually broken – usually the lock hardware itself, not the whole door.
CGI Parts & Our Repair-vs-Replace Approach
For CGI product, we use genuine replacement parts whenever they remain available – especially impact glazing and multi-point lock hardware, where the original engineering matters. If CGI has discontinued a part or the lead time is measured in months, we source premium aftermarket equivalents that meet or exceed the original spec, and we show you the difference before we install anything. You’ll never wonder what went into your window.
We stock common CGI hardware locally in CGI Windows & Doors in Windcrest, TX and across San Antonio for fast turnaround: balance shoes for Classic 2100 sashes, rollers for Estate Collection sliders, weatherstripping for Targa casements, and multi-point lock components for impact doors. That means less waiting and fewer return trips. When a repair isn’t the right call – a failed IGU in a 20-year-old Sentinel with a corroded frame, for example – we’ll tell you plainly and give you a written price for full replacement instead of patching a window that’ll fail again in two years. If the numbers don’t make sense on paper, they won’t make sense on your wall either. Call (903) 488-7019 for an honest read on your CGI product.
Our CGI Service Process – Step by Step
- 1
Diagnosis. Our tech examines the product in place – sash operation, glass condition, frame alignment, hardware function. We identify the specific failure point on your CGI model, not just the symptom. For a fogged Sentinel IGU, we confirm the seal failure and measure the exact glass dimensions.
- 2
Written price. Before any work starts, you get a line-item price in writing. That covers parts, labor, and any adjustments. No estimate that morphs into a surprise invoice – the number we give you is the number you pay.
- 3
Repair or replacement. We use genuine CGI parts where they exist, premium aftermarket where they don’t, and we do the work carefully – pulling sashes the right way so the frame isn’t scored, setting glass with proper bedding so the new IGU sits true.
- 4
Test and verify. After the repair, we operate the window or door multiple times, check the seal, and verify the lock engagement. A Classic 2100 that got new balances should glide with two fingers and lock without forcing. We don’t call it done until that’s true.
- 5
365-Day Done Right Promise. Every CGI repair and installation is covered in writing for a full year, parts and labor. If something isn’t right, Juniper makes it right. No charge, no argument.

FAQs – CGI Windows & Doors Service in San Antonio
No – we are an independent CGI service provider, not a CGI-authorized dealer or factory rep. That independence works in your favor: we recommend the fix that’s right for your home and budget, not the one a manufacturer would prefer us to sell.
Yes, whenever CGI still makes the part and it’s available in a reasonable timeframe. That includes impact glazing and multi-point lock hardware, where original specs matter most. If a part is discontinued or backordered too long, we source premium aftermarket equivalents that meet or exceed the original spec, and we tell you before we install.
Most common repairs – balance replacement, track cleaning, weatherstripping, lock hardware – are done in a single visit, usually one to three hours depending on the product. IGU replacements take longer because the glass has to be fabricated to the exact dimensions. We’ll give you a real timeline at the estimate. Call (903) 488-7019 to schedule.
We service Sentinel, Classic 2100 Series, Estate Collection, and Targa – the full CGI residential lineup. That includes single hungs, double hungs, sliders, casements, awnings, fixed lites, and impact-rated doors.
Here’s the honest answer: performing a repair on any product can have warranty implications depending on the original terms and whether the product is still covered. We’re careful to use OEM-spec parts and proper installation techniques that align with warranty requirements. We’ll flag any potential warranty issue during the diagnosis before you commit to anything.
For repair work, expect roughly $150 – $450 for typical hardware fixes – balance replacement, track cleaning, weatherstripping, lock repair. IGU replacement runs higher because of the glass fabrication: usually $350 – $900 per unit depending on size and glazing. Full frame replacement for CGI product in San Antonio typically starts around $1,200 – $1,800 per opening and goes up from there based on impact glazing and frame condition. Every job gets a written line-item price before work begins. Call (903) 488-7019 for an exact quote – estimates are free.
That’s a seal failure. The dual-pane insulated glass in your Sentinel has a spacer seal that keeps moisture out, and once it fails, outside air and humidity seep between the panes. You’ll see fog or condensation that won’t wipe off from either side. The fix is replacing the IGU with a new insulated unit matched to your frame – we measure, order, and install it so the window looks and performs like factory original.
Usually, yes. The most common causes are worn rollers, a shifted frame from San Antonio’s expansive clay soil, or debris packed into the bottom track. We inspect the rollers first, then check the frame alignment, then clean and adjust. If the door’s been binding for a long time, the panel may need re-shimming. Most of these we fix same visit.
It depends on the frame and the glazing channel. CGI’s welded frames can often accept laminated impact glass if the frame is in good condition and the sash depth allows it. For a Classic 2100 or Sentinel with a sound frame, we may be able to replace the glass only. We’ll measure, spec the option, and give you a written price before any work starts. Call (903) 488-7019 for a free assessment.
We stock the components – balance shoes, tilt latches, lock hardware – more than complete pre-assembled sashes, because wait times on full factory sashes are long and most failures don’t require one. When the sash itself is damaged beyond component repair, we order the replacement and give you a real ETA. In many cases, we can rebuild the existing sash in our shop faster than the factory can ship a new one.
Yes. The most common cause on Targa casements is compression-set weatherstripping – after years of San Antonio heat, the weatherstripping loses its rebound and doesn’t seal. We replace the weatherstripping with OEM-spec material and adjust the sash so it seats evenly against the frame. It’s a straightforward fix and usually done in under an hour per window.
