CGI Construction in Schertz, TX | Elmstead Remodeling San Antonio
We provide independent CGI window and patio door service across Schertz, from the new subdivisions along I-35 to the older ranch homes off FM 3009. The work we do here is shaped by one local fact most contractors miss: Schertz sits on heavy clay that shifts with rain, and that movement bends window frames in ways you won’t see in San Antonio or New Braunfels. If you’re dealing with a CGI window or sliding door that binds, leaks, or won’t close, call us at (432) 233-0976 for a free estimate. We’re Elmstead Remodeling San Antonio, your General Contractor in Schertz, and we’ve been fixing CGI products in this city long enough to know what the dirt does to them.
Why Schertz Residents Choose Us for CGI Service

Our crew has pulled apart CGI windows and doors in every corner of Schertz, and we’ve learned what fails here, why it fails, and when a repair beats a replacement. That matters because CGI products aren’t cheap, and the wrong diagnosis can cost a family thousands. Graham Stein, our owner, trained in construction decades ago and has worked on homes throughout the San Antonio area, including the kind of aging builds that dominate older Schertz neighborhoods. When we show up, the written scope comes with us – you’ll see the price before any work starts, and that’s the price you pay, no line items added after demo day.
We are an independent CGI service provider, not a manufacturer-authorized dealer. That independence means we recommend repairs when they make sense, not when a sales quota says to. You can read more about how we source and install these products on our CGI sales & service page.

Common CGI Construction Problems We Solve in Schertz
These are the five issues we see most often in Schertz homes, each tied to something specific about this city’s climate, soil, or housing stock:
- Racked frames on CGI Classic Series sliders. In 1970s and 80s ranch homes along the older streets near Main Street, slab-on-grade foundations shift with the clay beneath them. The slider frame racks, the rollers bind, and the panel drags. We re-shim the frame, replace the rollers with OEM parts when available, and get the door gliding again.
- Warped sill tracks on CGI Estate Collection picture windows. South-facing elevations take direct sun for ten hours a day in a Schertz summer, and that heat warps aluminum sill tracks. The seal fails, condensation builds between the panes, and the window looks fogged. We replace the track and re-glaze the unit when the glass is still sound.
- Improperly shimmed CGI Sentinel impact windows in new subdivisions. Homes built after 2000 in master-planned communities like Fairways of Schertz and Carolina Crossing sit on post-tension slabs that still settle. When the rough opening shifts out of square, gaps open around the window, and air and water move through. We pull the trim, re-shim the frame, and seal it properly.
- Stripped operator gears on CGI casement windows. After heavy rainfall cycles, the clay around a Schertz foundation swells and pushes the rough opening against the window. Homeowners force the crank against that pressure, and the gears strip. We replace the operator and adjust the frame so the crank turns without resistance.
- Fogged glass on older CGI units. Once a seal fails on a west-facing window, the heat and humidity do the rest. We replace insulated glass units on site when the frames are still square, which costs far less than a full window replacement.
CGI Service in Schertz: What Local Conditions Mean for Your Equipment

The most overlooked factor in Schertz CGI work is the city’s noise ordinance tied to school hours. Concrete pours and heavy equipment operation are restricted to after 9 AM during the school year, which is a quirk local contractors have learned to plan around and outside crews routinely miss. For a family in Carolina Crossing, that means an impact window tear-out with concrete-filled frame anchoring can’t start at 7 AM like a generic San Antonio crew might schedule it. We arrange our anchors and tear-outs for after morning drop-off, which keeps the job code-compliant and keeps your neighbors from filing a complaint. It’s a small scheduling shift that saves homeowners from a stop-work order mid-project. Our Schertz service area coverage is built around these local rhythms, not against them.
Then there’s the soil itself. Schertz sits in a transition zone between the dry Hill Country and the wetter Blackland Prairie. The clay here shrinks in drought and swells after a hard rain, and that movement transmits directly into window and door rough openings. A CGI frame anchored with the wrong fastener pattern will still shift. We account for that on every install and every repair, which is why our work in Schertz holds up better than work done by crews who treat every city the same.
CGI Models & Products We Service in Schertz
We work on the full CGI residential line: Classic Series sliding glass doors, Estate Collection casement and picture windows, Sentinel Series impact-rated windows, and Craftsman Series single-hung windows. For warranty-critical impact assemblies, we use genuine CGI rollers, balances, and weatherstripping when they’re available. For out-of-production lines where OEM parts are cost-prohibitive, we recommend quality aftermarket glazing and hardware that matches the original spec. We stock common CGI parts locally for faster Schertz turnaround, so a repair doesn’t stall while a part ships from the factory. We repair frames and operators where possible, and we replace full units only when the sash or glass is compromised, or the frame is out of square beyond what shimming can correct.

AfterCGI Service Pricing in Schertz

Here’s what CGI work typically costs in the San Antonio market, including Schertz. These ranges reflect what we see on completed jobs, not a national average:
| Service | Typical Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
| Roof Replacement | $8,000 – $20,000 |
The final price depends on how many openings you have, whether the frames are out of square, and what condition the surrounding trim is in. A single Classic Series slider repair might run toward the lower end of the window replacement range, while a full impact window package on a two-story home lands higher. Every free estimate includes a written line-item price, so you’ll know exactly what you’re paying before we start. Call (432) 233-0976 to schedule yours.

FAQs – CGI Construction in Schertz
Yes. The expansive clay under Schertz moves more than the soil in San Antonio or New Braunfels, and that movement pulls rough openings out of square. We use a fastener and shim pattern designed for the local soil profile, not a generic install spec, which keeps the frame from shifting after the first wet season. If you’re in a home built on the 1970s-80s slab-on-grade stock near Main Street, this matters even more. Call (432) 233-0976 and we’ll walk you through what your specific house needs.
Yes, in most cases. We pulled a Classic sliding door in a 1980s home off FM 3009 after the homeowner said it jammed every morning. The bottom track had bellied 3/8 inch where the slab settled. We ground and re-shimmed the frame, replaced the rollers with OEM parts, and re-set the panel to glide. No full door replacement needed. If your door binds, call us before you price a new one, because a repair often costs a fraction of a replacement.
It means tear-outs and heavy equipment work can’t start before 9 AM during the school year. We schedule impact window tear-outs and concrete-filled frame anchoring after that window opens, which keeps the job compliant and spares you a code enforcement visit. It pushes the workday later by an hour, but it’s the law in Schertz and we plan for it.
For warranty-critical parts like rollers, balances, and weatherstripping on Sentinel Series impact assemblies, expect one to two weeks from order to arrival, depending on the factory queue. We stock the most common CGI parts locally, so basic repairs can happen same-week. If a part is backordered, we’ll tell you before you commit. Call (432) 233-0976 for exact lead times on your model.
CGI frames and glass are built for coastal hurricane zones, so the heat alone won’t destroy them. What we see in Schertz is UV degradation of seals and gaskets on west-facing elevations over time, which leads to fogged glass and reduced impact rating. The fix is proactive re-glazing and gasket replacement before the seal fails completely. If you’ve got a west-facing CGI window that’s starting to fog, call (432) 233-0976 for a free evaluation.
