CGI Construction in Selma, TX | Mason Remodeling Co San Antonio
We provide independent CGI window and impact-glass service across Selma, TX, handling everything from failed seals and frame racking to full replacement of Sentinel, Estate, Craftsman, and Classic Series units. Most Selma calls we take involve either condensation between panes from humidity cycling or frames that have shifted due to the area’s expansive Blackland Prairie clay. One call to (254) 269-5071 gets you a straight answer on whether that window needs a sash replacement or a full-frame rework, and we’ll put the price in writing before any work starts.
Our crew has been working San Antonio-area jobs for years, and we know CGI products specifically: their glazing beads, their corner joinery, their impact-rated laminates, and where they fail when a Selma home moves. We’re not a manufacturer-authorized shop. We’re an independent CGI sales & service provider, which means we fix what’s actually broken using the right part for the job, not the part a corporate program tells us to push. Isaac Pruett, our owner, grew up learning construction at Los Angeles Trade-Technical College and has spent two decades swinging hammers across the Southwest. His crew has handled everything from gut renovations near the King William Historic District to quiet kitchen rebuilds in suburban lots, and he’s known for getting the scope right the first time so the invoice stays predictable and the callbacks stay rare.
Why Selma Residents Choose Us for CGI Service

Selma sits on the edge of the Texas Hill Country, and its housing stock is mostly suburban tract development from the late 1990s onward. That means a lot of production-built homes with CGI windows installed when the house was new, now hitting the 10-to-20-year mark where seals start to fail and frames start to show what the clay underneath has been doing. We know these homes because we’ve worked inside them. We’ve pulled CGI sashes in Retama Springs, off Lookout Road, and across the master-planned communities that run up and down the I-35 corridor.
Every Mason Remodeling technician is background-checked, identity-verified, and shows up in a clean marked uniform with a photo ID badge at the door. Before the visit, you get the technician’s name and photo so you know exactly who’s walking up your driveway. That’s the Threshold Standard, and it matters when you’re home alone, when the kids are napping, or when you’d rather not open the door to a stranger in an unmarked truck. We put the price in writing before tools come out, and every CGI job we complete is covered by our written guarantee, plainly stated: 365 days from completion, and if the work isn’t right, we return and make it right at no cost.

Common CGI Construction Problems We Solve in Selma
- Failed seals and condensation between panes. Selma’s hot, humid summers and sharp temperature swings force the glazing beads on CGI Sentinel Series impact windows to work loose over time. Once the seal breaks, moisture gets between the laminated panes and you get that cloudy film you can’t wipe off. We replace the sash or re-glaze the unit, depending on what the frame will allow.
- Loose aluminum corner joints after storms. Spring hailstorms and high winds near the Cibolo Creek floodplain put real stress on Sentinel Series corner joinery. We see aluminum frames that have loosened at the miters, and if left alone, the sash starts to sag and bind against the frame.
- Peeling or blistering pre-finished cladding. The Estate Collection’s wood-clad exteriors take a beating from prolonged sun exposure on Selma’s south and west elevations. When clay-soil settling causes the rough opening to rack even slightly, that cladding cracks or blisters faster than it should. We address the frame issue first, then the finish.
- Stress cracks in laminated glass. The Blackland Prairie under Selma expands and contracts with moisture, and differential slab movement transfers up through the rough openings. That shows up as hairline cracks at the corners of impact-rated laminated glass, typically on larger fixed units. Replacing the glass won’t fix the cause if the opening has moved, so we take measurements and tell you the truth about what’s happening.
- Operator hardware binding on casements. When a frame goes out of square from settling, casement operators start to grind and strip. We see this on Craftsman and Classic Series casements in older Selma neighborhoods near Cibolo Creek. We recalibrate or replace the hardware after checking the frame for racking.
CGI Service in Selma: What Local Conditions Mean for Your Equipment
Selma’s location on the Blackland Prairie is the detail that separates CGI service here from a generic window call anywhere else in Texas. The soils under Selma are expansive clays that swell when wet and shrink when dry, and they do not move uniformly. One corner of a slab drops an eighth of an inch while the other stays put, and the window frames embedded in that wall start to rack. We measure this on nearly every older home we service near the Cibolo Creek floodplain, where differential settling is more pronounced than in the newer subdivisions further east. A CGI window that was square when it was installed in 2005 may be out of plumb by a quarter inch today. That racking is what causes the laminated glass stress cracks, the binding casements, and the seal failures we listed above. It is also why we inspect the rough opening and frame before we order a replacement sash or full unit. Compare this to nearby Schertz, which sits more on limestone bedrock, and the same house age produces far fewer racking complaints. Selma deals with clay. We plan for clay. If we replace a CGI-unit without accounting for that movement, we’ve set you up for the same failure in a few more years, and that’s not how we work.
CGI Models & Products We Service in Selma
We service the full residential CGI lineup that shows up in Selma homes: Sentinel Series impact-resistant windows, Estate Collection wood windows, Craftsman Series, and Classic Series. When a repair requires exact physical dimensions or impact certification, especially on Sentinel pinned or laminated units, we use genuine CGI OEM parts. For common hardware, weep covers, screens, and fasteners, we’ll often use high-quality aftermarket equivalents to keep the bill reasonable, and we always tell you before we proceed. We keep common CGI hardware and seal components stocked for fast turnaround across Selma, which means fewer days waiting on a parts truck and fewer days with a taped-up window. If you’re not sure which series you have, send us a photo or read us the etched marking on the corner of the glass during the call; we’ll identify it from that.
CGI Service Pricing in Selma
CGI work in Selma falls into a few clear buckets, and we’d rather you know the ranges before you call than wonder if you’ll waste a phone call. Impact window installation runs $8,000 to $25,000 depending on how many openings and what the structural demands of the wall are. A window replacement on a standard Selma home typically lands between $4,500 and $15,000. If you’re adding square footage and need CGI-compatible window and door packages tied into a General Contractor - Selma home addition, budget $45,000 to $130,000 for the full scope. What drives the price is the frame condition, the number of units, whether the openings have racked from clay movement, and what your HOA requires for exterior appearance. Every estimate we write is a fixed, line-item price, not a loose verbal number. Call (254) 269-5071 and we’ll walk the site, take measurements, and put it in writing.

FAQs – CGI Construction in Selma

Yes. In most Selma homes, we replace the failed sash or re-glaze the unit rather than swapping the entire frame, provided the frame itself is still square and structurally sound from the clay-related movement we check for on every visit. The cost depends on the sash size and whether it’s a pinned or laminated Sentinel unit, but you’ll get a written fixed price before the work starts. Call (254) 269-5071 for a free estimate.
Yes, it does, and we see it repeatedly. The Blackland Prairie clays under Selma swell and shrink with moisture changes, causing differential slab movement that transfers into the rough openings. CGI frames installed in those openings can rack a quarter inch or more over a decade, producing the binding, cracking, and seal failures we described above. We measure the opening before we order parts because a replacement installed into a racked frame will fail the same way again.
It depends on the part. For anything tied to impact certification or exact structural dimensions, like Sentinel laminated sashes or pinned corner hardware, we use genuine CGI OEM components. For common items like weep covers, screens, and standard fasteners, quality aftermarket equivalents are often identical in fit and function at a better price. We’ll tell you which route we recommend on your specific window and why before we order anything.
Yes, we can match the unit as closely as the aging of the original finish allows. Estate Collection wood windows that have been in Texas sun for 10 or 15 years will have a finish that’s mellowed, so a brand-new factory finish won’t match perfectly day one. We’ll show you options for finish matching or refinishing the adjacent units so the elevation reads as one plane. The frame dimensions and profile will match exactly; the finish is the only variable that takes some judgment.
We start by reviewing your HOA’s architectural guidelines, then spec our Bathroom Remodeling in Selma replacement to match the approved finish, grid pattern, and profile already on the home. Many Selma subdivisions with CGI windows fall under HOA review, and we’ve worked through enough of those submissions to know what typically gets approved without back-and-forth. We can provide submittal-ready spec sheets for the HOA board. Call (254) 269-5071 and mention your HOA up front; we’ll walk you through what you need before you file anything.
