Why San Antonio Homeowners Choose CGI Construction
Elmstead Remodeling San Antonio provides independent San Antonio Cgi service across San Antonio, from impact-rated window replacement to sliding glass door repair and the roof work that often accompanies both. We service and install CGI Sentinel Series, Estate Collection, 960 Series sliding glass doors, and Trussville Series aluminum windows, and we do it without ever pretending to be the manufacturer. We’re an independent contractor, which means we answer to you, not to a corporate warranty department. When your CGI windows fog, stick, corrode, or crack after a hailstorm, call (432) 233-0976 and a live person picks up.
What sets our CGI work apart is that we document what we find. Graham Stein, our owner, writes every scope of work down before a single tool leaves the truck. The written price you sign is the price you pay. If you want to understand exactly what’s wrong with your CGI window or door and exactly what it costs to fix, you’ll get that from us. If you’d rather wonder, we’re not the right fit.
We are not affiliated with or authorized by CGI. We never claim to be. We’re simply a General Contractor whose crews have spent years taking apart, repairing, and reinstalling CGI products in this city’s specific conditions: brutal summers, hail season, and soils that move.
Why Trust Elmstead Remodeling San Antonio for Your CGI Construction?
CGI products are built for impact resistance. That’s not just marketing: the laminated glass, reinforced frames, and multi-point locking hardware are engineered to a standard. But that engineering also means any repair has to respect the original rating. A shortcut part, a generic roller, a glass unit that isn’t impact-rated, and you’ve quietly turned a hurricane-rated window into a regular one. We don’t do that.
Our technicians work with CGI Sentinel Series and Estate Collection windows regularly enough to know their specific anatomy: the interlayer in the laminated glass, the way the weep system drains, the exact profile of the frame gaskets. That familiarity matters when you’re diagnosing a fogged unit in a Stone Oak home or a sticking 960 Series door in Alamo Heights or a CGI Construction in Fair Oaks Ranch, TX. We stock direct-matching CGI impact-rated insulated glass units and the rollers, gaskets, and hardware these products actually use, not just whatever fits from a supply house shelf.
Graham Stein grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending decades framing, finishing, and fixing. He’s worked across San Antonio for years, including projects near the King William Historic District where older homes demand patience and an eye for original detail. When his crew takes on a CGI repair in a historic home, the goal isn’t just a working window. It’s a window that doesn’t look like an afterthought against original trim.
And because this is Elmstead Remodeling San Antonio, a Cedarwell company, certain things are non-negotiable. Drop cloths on the floors. Shoe covers at the door. A written price before work starts. A photo of the clean-up before the crew leaves. A live person answering the phone 24/7. The 365-Day Done Right Promise on every completed project: if it’s not done right, we make it right.

Common CGI Construction Problems We Fix in San Antonio
Here’s what we actually see on service calls across San Antonio, not what a brochure says could happen:
- Thermal seal failure in dual-pane CGI windows. San Antonio’s summer heat is relentless. The seal between the panes fails, moisture gets in, and the window fogs from the inside. We see this most often in CGI Sentinel Series units on west-facing walls that take full afternoon sun. Once the seal is gone, the insulating value drops and the glass needs replacement. This is not a cleaning issue.
- Weathered gaskets and worn rollers on CGI 960 Series sliding glass doors. These doors are heavy by design. Over years of daily use and San Antonio’s dust, the rollers wear down and the gaskets lose their give. The door starts to stick, drag, or sit crooked in the frame. Replacing rollers and gaskets before the frame itself gets scored saves money.
- Stress cracks in CGI aluminum frames after hail impact. Hailstorms here are serious. Even when the impact-rated glass holds, repeated strikes can stress the aluminum frame around it. Hairline cracks at corners or along the extrusion aren’t just cosmetic. They compromise the frame’s structural integrity and can let water in.
- Corrosion on CGI hardware and weep system components. Homes with pools, or anything near a high-chloride environment, put CGI hardware in contact with airborne chemicals. The weep system exists to drain water; if it corrodes and blocks, water sits inside the frame. We clean, replace, or re-route weep components so drainage actually works.
- Fogged CGI Estate Collection windows after rain or humidity swings. Estate Collection windows use the same dual-pane construction as Sentinel, and they fail in the same way when the seal degrades. The question owners ask us is whether it’s a factory defect. Usually it’s not; usually it’s age and heat cycling. We’ll tell you which one it is, and we’ll write that down too.
CGI Parts & Our Repair-vs-Replace Approach
We use genuine CGI replacement parts, including impact-rated glass and hardware, to maintain the original performance ratings. That’s the default. Not a generic insulating glass unit that happens to fit, not a roller we found online. If a CGI product is going to keep its impact rating, it needs CGI-spec parts.
There’s a difference between a repair and a shortcut. When a CGI unit has one failed seal and otherwise sound glass, replacing the insulated glass unit makes sense. When multiple seals have failed, or the frame shows structural damage from hail or stress, repair may not restore the original impact resistance. At that point we recommend full replacement, and we tell you why in writing. Our local stock includes direct-matching CGI impact-rated insulated glass units, rollers for 960 Series doors, and the gaskets and hardware these products actually use. That means less waiting on freight from the distributor and fewer second visits.
If you’re not sure whether your CGI repair is worth doing, call (432) 233-0976 and describe what you’re seeing. We’ll give you a straight read.
Our CGI Service Process – Step by Step
- 1
Diagnosis. We inspect the unit in place: glass, frame, gaskets, rollers, weep system. We identify the failure mode and write it down. For a fogged Sentinel, that means confirming the seal failure and checking the frame for secondary damage.
- 2
Written scope and price. You get a written scope of work and a written price before any work starts. No estimates that grow after the crew arrives. This is Graham’s rule: write it down, price it once, do it right.
- 3
Repair or install. We use genuine CGI parts. For a glass swap, that means the direct-matching impact-rated insulated glass unit, installed with clean gaskets and proper drainage. For a door, new rollers, realigned frame, and tested operation. Shoe covers go on at the door, drop cloths go down, and we ask before moving anything.
- 4
Testing. We test the unit: smooth operation, proper drainage, no air leaks, no binding. We check that the weep system drains and that the hardware engages correctly.
- 5
Clean-up and photo. We clean the work area, take a photo of the clean-up before the crew leaves, and walk you through what we did. Then the 365-Day Done Right Promise applies: if it’s not done right, we make it right.

AfterCGI Products We Service & Install in San Antonio
Our crews work hands-on with four CGI product lines most often found in San Antonio homes and commercial buildings:
- CGI Sentinel Series impact windows – dual-pane impact-rated windows common in high-end residential projects.
- CGI Estate Collection impact windows – residential impact windows with a broader design range.
- CGI 960 Series sliding glass doors – heavy sliding doors known for smooth operation when properly maintained.
- CGI Trussville Series aluminum windows – aluminum-frame windows that appear in both commercial and residential settings.
In local stock we keep direct-matching CGI impact-rated insulated glass units, replacement rollers and gaskets for 960 Series doors, and the hardware these systems use. Not everything, but the parts we reach for most on service calls.
We Also Service These Brands
CGI is one part of what our crews work on. We’re equally familiar with KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, Kohler fixtures, and James Hardie exteriors. That matters because window replacement in San Antonio often runs alongside other work: a sill that needs rebuilding, trim that needs matching, a roof repair above the window that let water in first. We can handle the whole scope without handing you off to a third crew.
FAQs – CGI Construction Service in San Antonio
Is Elmstead Remodeling San Antonio authorized by CGI?
No. We are an independent CGI service provider, not an authorized dealer or factory affiliate. That means we make repair and replacement decisions based on what’s right for the building and the homeowner, not on what a manufacturer’s program dictates. The products we service are CGI products, and the parts we use are genuine CGI parts, but we are not CGI.
Can you repair a broken glass pane in my CGI Sentinel Series window, or do I need a full sash replacement?
We can replace the insulated glass unit in most Sentinel Series windows without replacing the entire sash, as long as the sash frame is structurally sound and the seal failure is limited to the glass unit itself. If the frame has stress cracks or the hardware is compromised, a full sash replacement is the safer path. Call (432) 233-0976 with the window’s location and what you’re seeing, and we’ll help you figure out which route fits. Estimates are free.
I have a CGI Estate Collection window that fogs up between the panes after rain. Is that a factory defect?
Usually not. Fogging between panes almost always means the thermal seal has failed, and in San Antonio that failure is typically driven by years of heat cycling rather than a manufacturing defect. If your windows are still under warranty, we’ll help you understand what documentation you need. If they’re not, we’ll give you a written price for a direct-matching impact-rated glass unit replacement. Call (432) 233-0976 and we’ll walk through it with you.
My CGI 960 Series sliding glass door is hard to open and the rollers look worn. Do you stock replacement rollers?
Yes. We stock replacement rollers for the 960 Series locally because worn rollers are the single most common service issue we see with these doors in San Antonio. In most cases the door can be restored to smooth operation with new rollers and fresh gaskets, without replacing the entire door. Call (432) 233-0976 and we’ll schedule an inspection and give you a written price.
Will replacing my old windows with CGI impact windows affect my HOA approval in San Antonio?
It can, depending on your subdivision’s covenants and design guidelines. Many HOAs in San Antonio require written approval before exterior window changes, and some specify frame color or style. We’ll help you gather the product spec sheets and installation details your HOA asks for, but the approval process itself sits between you and the board. Start early, because San Antonio HOA reviews can move slowly.
How do you handle disposal and recycling of old CGI window units during a replacement?
We remove the old units, including the laminated glass, and handle disposal according to local San Antonio waste requirements. Laminated impact glass cannot go into standard single-stream recycling in most cases, so we separate what can be recycled from what must be disposed of. The work area is cleaned before the crew leaves, and we photograph the clean-up as proof the space was left right.
How much does CGI construction cost in San Antonio?
Here are the price ranges we typically quote for the relevant scopes:
| Project Type | Price Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
| Roof Repair | $400 – $1,800 |
These are ranges, not quotes. Your written price comes after we see the project. Call (432) 233-0976 for an exact quote; estimates are free.
