Why San Antonio Homeowners Choose CGI Construction
We’re an independent San Antonio Cgi service provider, and yes, we repair and install CGI windows and doors without being tied to the manufacturer. That means we’re free to give straight advice on repair versus replacement, use the best parts for your budget, and never push a full order when a $400 hardware swap fixes the problem. Call (432) 547-6806 for a free estimate on any CGI window, door, or impact-rated opening in the San Antonio area.
CGI built its name on impact-rated windows and doors that hold up to hurricane winds and flying debris. San Antonio isn’t a coastal city, but our heat, hail, and occasional severe thunderstorm winds put real stress on window frames, seals, and hardware. Our team has serviced CGI Classic Series single-hungs in older central neighborhoods, replaced fogged Estate Collection fixed glass on west-facing walls in CGI Construction in Alamo Heights, TX, and installed new Sentinel Series units on custom builds throughout Bexar County. We know these windows, their hardware, and the specific ways San Antonio’s climate ages them.
Why Trust Sawyer Remodel San Antonio for Your CGI Construction?
Written Price Before Any Work Starts means you know the number before we touch a single screw. On every CGI repair or replacement, you get a written price up front. The invoice matches the approved quote. That’s The Relay Standard, and it applies to a broken hinge on a Targa casement or a full 20-window impact-rated installation.
Our technicians work with CGI products every week. We stock common OEM hardware locally – locks, hinges, rollers, weep hole covers – so a binding sash or broken lock isn’t a two-week waiting game. When glass needs replacing, we order custom-tempered low-E insulated units from San Antonio suppliers that meet or exceed the original thermal performance. We know which CGI frames take which glass thickness, which gaskets seal properly, and which aftermarket units match the original bronze or gray tint.
Luca Romano owns Sawyer Remodel San Antonio and still does a final walkthrough on every job. He learned the trade at Los Angeles Trade-Technical College and has been swinging hammers across the Southwest for decades. The craft comes first. Everything else follows. That’s why he checks every window we service before we call it done.
Background-checked, uniformed technicians show up when we say they will. You get a live arrival time, photo updates before and after, and a digital invoice you pay from a link. The 365-Day Done Right Promise backs every repair in writing. If it’s not done right, we make it right, for a full year after the project closes. No arguments, no chasing.

Common CGI Construction Problems We Fix in San Antonio
CGI windows are built tough, but San Antonio finds the weak points. Here’s what we see across the metro:
- Warped or binding sashes on CGI Classic Series single-hung windows. San Antonio’s summer heat and humidity cycling causes the vinyl to expand and contract, and older Classic Series units eventually bind. The window sticks halfway, or the balance system struggles. We replace the balance shoes and pivot bars with OEM parts, and in most cases the window operates like new without replacing the whole unit.
- Fogged or failed insulated glass units (IGUs) on CGI Estate Collection fixed windows. Western exposures in Alamo Ranch and Helotes take punishing afternoon sun. The seal between the two panes fails, moisture leaks in, and you get fog between the glass that won’t wipe clean. We replace the IGU with a custom low-E unit that matches the original tint and thermal performance – usually faster and less expensive than a full window replacement.
- Corrosion or pitting on CGI aluminum frames. Homes with saltwater pools see aluminum frame corrosion even in San Antonio’s semi-arid climate. Pool splash, high chlorine content, and humidity attacks the aluminum finish, especially around the bottom frame corners. We strip the corroded area, treat it, and refinish with a factory-match coating. In severe cases we recommend replacing the sash, not the whole window.
- Worn or broken locking mechanisms and hinges on CGI Targa casement and awning windows. Targa windows take a lot of cycles in San Antonio homes – opened nightly to catch the evening breeze, closed against the heat. The multi-point locks and stainless steel friction hinges wear out. We keep OEM Targa hinges and lock sets in stock, so a casement window that won’t seal or lock is usually a one-visit fix.
- Failed impact glass lamination or seal failure on CGI Sentinel Series windows. Sentinel is CGI’s heavy-impact line, and while the glass itself rarely shatters from everyday wear, the laminated layer can delaminate at edges over time, and the perimeter seals degrade in direct sun. We inspect the frame, glass condition, and seal integrity, then give you a straight repair-or-replace recommendation based on age and warranty status.
CGI Parts & Our Repair-vs-Replace Approach
We’re dealers of honesty, not just parts. When a CGI lock, hinge, roller, or balance system fails, we source OEM CGI hardware whenever available. Exact fit, same performance, no modifications. But for glass replacement, we use high-quality aftermarket insulated units from local San Antonio suppliers. These units meet or exceed the original thermal performance – matching the bronze or gray tint, the low-E coating, and the tempered impact rating – at a better price than factory-ordered glass.
Here’s how we decide repair versus replace: If the frame is square, the glass is intact, and the hardware is the problem, we repair. If the frame is severely warped, the IGU has failed on a 15-year-old window, or the energy loss is costing you real money on your CPS Energy bill, we recommend replacement. We’ll show you the numbers either way, in writing, with no pressure. Call (432) 547-6806 and we’ll give you a straight answer.
Our CGI Service Process – Step by Step
- 1
Diagnosis. We inspect the window or door in person. We check the frame for square, the glass for seal failure, the hardware for wear, and the opening for water intrusion around the CGI mounting flange. You get a written diagnosis with photos and a line-item quote before any work begins.
- 2
Repair or replacement. For repairs, we use OEM CGI hardware where it matters – locks, hinges, rollers, balance systems. For glass, we order custom low-E insulated units matched to your existing tint. For full replacements, we handle tear-out, disposal, and installation of new impact-rated windows with proper flashing and sealing.
- 3
Testing. We cycle every window and door multiple times. We check the locks engage, the sashes operate smoothly, the seals seat properly, and the glass is clear. We run a water test around new installations to verify the flashing and weeping systems work.
- 4
Warranty. Every repair and installation carries our 365-Day Done Right Promise in writing. If something isn’t right within a year, we come back and fix it. You also get a digital invoice and before-and-after photos for your records.

AfterCGI Products We Service & Install in San Antonio
We service the CGI Classic Series (single-hung, double-hung, sliders), the CGI Estate Collection (fixed, picture, and architectural windows), the CGI Targa Series (casement, awning, and hopper windows), and the CGI Sentinel Series (high-impact rated windows and doors for wind zones). We stock common OEM hardware locally in San Antonio for faster turnaround on Classic and Targa repairs, and we custom-order glass units for Estate and Sentinel applications from local suppliers.
For doors, we handle CGI impact-rated entry doors, French doors, and sliding glass door systems, including hinge, lock, roller, and threshold replacement.
One recent job sticks with us. Our crew replaced a bank of three fogged CGI Estate Collection fixed windows on a north-side home’s west-facing wall. We removed the old aluminum frames intact, ordered custom-tempered low-E insulated glass units to match the original bronze tint, and reinstalled them with new setting blocks and exterior glazing tape. The homeowners saw an immediate improvement in clarity and insulation, and the repaired units looked factory-original.
We Also Service These Brands
CGI is one lane we know well, but we’re not a one-brand shop. We also handle KraftMaid cabinetry, Cambria and Silestone countertops, and Kohler fixtures across San Antonio remodels. If your home has mixed brands and you need one General Contractor who can manage the whole scope, we’re built for that.
FAQs – CGI Construction Service in San Antonio
No. We’re an independent CGI service provider. That means we’re not beholden to the manufacturer’s sales targets or warranty restrictions, and we can recommend the best fix for your home – even if that fix is a high-quality aftermarket glass unit instead of a factory replacement. Call (432) 547-6806 for an honest assessment.
In most cases, yes – we can replace just the insulated glass unit. We remove the old frame intact, order a custom-tempered low-E IGU to match your original bronze or gray tint, and reinstall it with new setting blocks and glazing tape. A full window replacement only makes sense if the frame itself is warped, corroded, or leaking. Call (432) 547-6806 and we’ll tell you which one you need.
Yes, and it’s usually fixable without replacing the window. Our New Braunfels Cgi service area sees the same heat and humidity cycling that causes vinyl expansion and contraction, which wears out the balance shoes and pivot bars on older Classic Series single-hungs. We replace those components with OEM parts, and the window typically operates smoothly again in under an hour. Call (432) 547-6806 for a free estimate.
Yes. We install CGI impact-rated windows and doors for whole-house replacements across San Antonio, and we pull permits on every job. CGI’s Sentinel Series and other impact-rated lines meet the wind zone requirements for our region, and we ensure every installation passes inspection. Call (432) 547-6806 for a written quote on your scope.
Corrosion on CGI aluminum frames usually traces back to saltwater pool splash, high chlorine, or consistent humidity against the frame. We can often treat and refinish the corroded area without replacing the whole window. If the corrosion has compromised the frame’s structural integrity, we’ll recommend replacing the sash. Call (432) 547-6806 and we’ll assess it.
After the roof, but coordinate both. Replacing the roof first protects the new windows from debris, water, and construction traffic. But we coordinate CGI window replacement alongside roof work to get flashing and sealing right at the roof-to-wall intersection. Call (432) 547-6806 and we’ll talk through the best sequence for your home.
For CGI window work specifically, frame repair with hardware runs $400 to $1,800 per window, insulated glass unit replacement runs $600 to $2,500 per window, and a full replacement with a CGI-equivalent impact window runs $8,000 to $25,000 per opening installed. Here’s the breakdown:
| CGI Service | Price Range (San Antonio) |
|---|---|
| CGI window frame repair (per window, hardware) | $400 – $1,800 |
| CGI insulated glass unit replacement (per window) | $600 – $2,500 |
| Full replacement with CGI-equivalent impact window (installed, per opening) | $8,000 – $25,000 |
For related scopes, a full roof replacement in San Antonio typically runs $8,000 to $20,000, window replacement across the home runs $4,500 to $15,000, and impact window installation runs $8,000 to $25,000.
