CGI Construction in New Braunfels, TX | Sawyer Remodel San Antonio
We provide independent CGI service across New Braunfels, from Sentinel Series impact windows to vinyl siding and trim systems. Here’s the thing that makes our CGI work different here: we plan every exterior project around limestone bedrock, Edwards Aquifer impervious cover rules, and the humidity that rolls off the Guadalupe and Comal rivers. If you’re dealing with fogged CGI windows, warped siding, or failing trim on a pier-and-beam home, call (432) 547-6806 for a free estimate.

We’re Sawyer Remodel San Antonio, part of the Relay Home Co. family since 2005. Luca Romano leads our crew, and after decades swinging hammers from East LA to the Texas Hill Country, he still walks every job himself. Our team knows CGI materials because we’ve repaired and installed them on New Braunfels homes for years.

Why New Braunfels Residents Choose Us for CGI Service

CGI products are built for tough coastal weather, but New Braunfels throws its own curveballs: relentless Hill Country sun, flash-flood humidity, and limestone dust that gets into everything. We’ve seen what works and what doesn’t on homes here. That field experience means we don’t guess when a Sentinel window fogs or a siding panel buckles; we know the root cause and fix it so it stays fixed.
Luca learned the trade at Los Angeles Trade-Technical College before spending years on job sites across the Southwest. That background matters when you’re re-flashing a window against raw limestone or matching a discontinued CGI siding profile on a German-influenced historic home in downtown New Braunfels. Every job gets a written price before work starts, live arrival tracking, and photo updates. We’re not a franchise, and we hold our work to The Relay Visibility Guarantee: who’s coming, when they arrive, and what it costs, all confirmed before a single tool is picked up. Our New Braunfels service area page covers the neighborhoods we work in most.

Common CGI Construction Problems We Solve in New Braunfels
- CGI vinyl siding buckling or warping on west-facing walls. The direct afternoon sun in New Braunfels heats textured vinyl profiles unevenly, especially when the backing traps heat against stucco or masonry. We pull the warped panels, check the nailing pattern and expansion gaps, and reinstall or replace with UV-stable materials that hold their shape.
- CGI impact window seal failure near the Comal and Guadalupe rivers. Humidity and temperature swings cause the insulating gas to escape and the seals to fog between panes. We replace the glass unit with OEM CGI glass when available, keeping the original frame intact.
- CGI window rollers and locks seizing from limestone dust. Fine caliche dust blows off construction sites and dry creek beds throughout New Braunfels. It works into tracks and locking mechanisms until sashes stick or won’t lock. We clean and rebuild the hardware, or replace it with OEM parts if it’s beyond saving.
- CGI trim and fascia joints opening at corners on pier-and-beam homes. The expansive clay under much of New Braunfels shifts with moisture, and pier-and-beam foundations move with it. Corner joints on CGI trim open up, inviting moisture and pests. We re-secure and seal those joints properly.
- Standing seam metal roof issues where limestone reflection intensifies heat. Caliche patios and exposed limestone reflect heat upward, stressing roof fasteners and sealant. We inspect and repair standing seam metal roofs using CGI-compatible materials, including re-seating fasteners and replacing worn butyl tape at penetration points.
CGI Service in New Braunfels: What Local Conditions Mean for Your Equipment

Here’s something you won’t read on a generic CGI page: any exterior CGI product on a New Braunfels home within the Edwards Aquifer Contributing Zone must meet impervious cover limits. That means a siding or drainage retrofit isn’t just about the envelope; it’s about how much of your lot sheds water versus letting it soak in. When we plan CGI siding replacement or exterior trim work on homes off Gruene Road or along the river, we factor in permeable areas and drainage paths so your project doesn’t trigger a compliance headache. The same rules apply to patio covers, carports, and any structure that changes how water moves across your property.
This isn’t a factor in San Antonio or Universal City the same way. New Braunfels sits directly over a recharge zone for the aquifer that supplies drinking water across the region. Contractors who treat New Braunfels like just another Hill Country town end up fighting inspectors or, worse, leaving homeowners with drainage problems that show up two years later as foundation movement. Our crew plans CGI work around aquifer rules from the first site visit, not as an afterthought.
CGI Models & Products We Service in New Braunfels
We work on the full CGI lineup you’re likely to find on New Braunfels homes:
- CGI Sentinel Series impact windows – the workhorse line with laminated glass designed for storm zones. We handle glass unit replacement, sash replacement, hardware rebuilds, and re-flashing.
- CGI Estate Collection impact windows – the higher-end architectural line. We match frames, replace warped sashes, and address seal failures without tearing out the entire opening.
- CGI Vinyl Siding – various profiles including clapboard, dutch lap, and board-and-batten. We repair, color-match, and replace sections where Hill Country sun has done its work.
- CGI Trim & Fascia systems – corner posts, fascia boards, soffit, and window surrounds. We fix joints that have opened on shifting pier-and-beam homes and seal against moisture and pests.
On parts, we use OEM CGI replacements first. If a profile is discontinued, we spec aftermarket vinyl or window components matched for dimensions and UV resistance so the repair doesn’t look like a patch job. For New Braunfels turnaround, we keep common CGI hardware and sealants on hand so we’re not waiting on a shipment from Florida while your window won’t lock.

FAQs – CGI Construction in New Braunfels
Homes near the Guadalupe and Comal rivers in New Braunfels sit in a humidity pocket that most of the Hill Country doesn’t experience, which is why our Bathroom Remodeling in New Braunfels accounts for moisture control in every project. The high moisture content in the air, combined with New Braunfels’ hot days and cool nights, puts constant stress on window seals. When the desiccant inside the spacer bar saturates, the glass fogs between panes. We replace the glass unit with OEM CGI glass so the frame and hardware stay original. Call (432) 547-6806 for an exact price; estimates are free.
Yes, most of the time we can match it closely. CGI has shifted its color palette over the years, so some older Gruene and downtown New Braunfels homes have colors that are no longer manufactured. We source high-quality aftermarket vinyl in dimensions and UV resistance that match the original, and we check the match in direct Hill Country sunlight before installing. If an exact match isn’t possible, we’ll tell you honestly and discuss re-siding an entire elevation so the repair doesn’t stand out.
Limestone near the surface means shallow footings and less room to maneuver flashing and trim at grade level. On pier-and-beam homes, the piers shift with the expansive clay, so CGI trim joints at corners and transitions open over time. We re-secure the trim with fasteners that allow for movement, then seal with a flexible butyl tape that won’t crack when the structure breathes. The goal is a watertight joint that still lets the house move the way it’s designed to.
It depends on where your home sits. New Braunfels properties within the Edwards Aquifer Contributing Zone or Recharge Zone have strict impervious cover limits. If your siding replacement expands a footprint, adds a patio cover, or changes drainage so more water runs off than soaks in, you may need city or county review. We’ll flag this during the estimate and help you figure out what’s required. Call (432) 547-6806 and we’ll check your property’s status before you spend a dollar.
If the sashes and frames are sound, repair is usually the cheaper path. A failed glass unit runs $450 to $1200 per window, while full replacement can hit $25,000 on a large home. But if the frames are warped from heat or the locking systems are cracked from dust and use, replacement is often the better long-term call. We’ll give you our honest read on repair versus replace during the free estimate.
