CGI Construction in Austin, TX | Penhallow Remodeling Austin

CGI construction service in Austin typically runs $1,200 – $3,500 per window opening for impact-rated installation, with full-frame replacements landing between $8,000 – $20,000 depending on the home’s age and framing condition. Penhallow Remodeling Austin is an independent CGI service provider serving homeowners across Austin from bungalows off South Congress to newer builds in Steiner Ranch, and the thing that sets our CGI work apart here is that we plan for clay soil movement before we ever set a window. We’re not manufacturer-affiliated, we’re not tied to a corporate script, and we’ll give you a written price before any work starts. Call (325) 225-5429 for a free estimate.

Why Austin Residents Choose Us for CGI Service

Trevor Nash has spent years working with CGI’s product lines across Austin’s specific remodeling demands, from pier-and-beam bungalows in Hyde Park to sprawling slab-on-grade ranches in Tarrytown. Our field crews train on CGI’s installation tolerances and finish systems, so we know exactly how their products behave in Central Texas heat, clay soil, and drought-flood cycles. We’re the local crew that handles CGI sales & service without the showroom markup or the manufacturer’s overhead, and we carry genuine CGI replacement parts on our trucks, not whatever the supply house had on sale.

Trevor grew up in Los Angeles and learned construction fundamentals at Los Angeles Trade-Technical College before swinging hammers on foundation repairs and full kitchen rebuilds. As a General Contractor in Austin, he and his crew have served local homeowners for well over a decade. If you’ve had work done near South Congress, there’s a fair chance Trevor’s team left the jobsite cleaner than they found it. That’s the standard we hold on every CGI window, door, and sliding glass replacement we touch.

Common CGI Construction Problems We Solve in Austin

  • Bowed frames and corner seal failure on older wood-framed homes. Austin’s expansive clay soil moves with every drought-flood cycle, and CGI impact windows installed on original 1940s framing can develop bowed frames when the rough opening shifts. We see this most often in central Austin neighborhoods where pier-and-beam foundations flex seasonally. The fix usually involves re-shimming and re-flashing the opening before resetting the window.
  • Sliding glass doors that bind at the strike stile after dry spells. CGI 800 Series sliders on slab foundations bind when the concrete settles unevenly after a long dry stretch. The fixed panel’s anchor screws often strip in pre-drilled holes on remodels where the original framing wasn’t square, and we re-anchor those with stainless hardware that holds in Austin’s shifting soil.
  • Uneven fading on west-facing CGI Estate Collection entry doors. Austin’s intense UV exposure fades dark exterior finishes unevenly on west-facing walls, especially in neighborhoods with no shade canopy. We refinish those doors with UV-stable coatings matched to CGI’s factory specs and recommend lighter finishes where the afternoon sun is brutal.
  • Condensation between glass panes in humid East Austin bungalows. CGI ImpactGuard casements in older East Austin homes show condensation between panes when the desiccant fails early from repeated daily temperature swings. That’s a glass unit replacement, not a full window swap, and we carry the impact-rated IGUs to do it.
  • Rotted wood sills from poor subfloor ventilation. In pier-and-beam homes across East Austin, moisture from crawl spaces rots window sills from the inside out. We reframe the rough opening with pressure-treated lumber before setting new CGI windows so the next thirty years don’t repeat the last thirty.

CGI Service in Austin: What Local Conditions Mean for Your Equipment

Austin’s Save Our Springs Ordinance restricts impervious cover in the Edwards Aquifer recharge zone, and that has a direct effect on CGI window and door work. Any replacement involving new exterior wall penetrations or added glazing area on our Bathroom Remodeling in Austin or similar projects in southwest Austin, especially near the recharge zone, can trigger a site plan review. That hurdle does not apply in Round Rock or Pflugerville, and it’s one of the first things we check before quoting a job in zip codes like 78735, 78737, and parts of 78749. If your home sits in that zone, we’ll tell you on the first call whether your window replacement is a straight swap or a permit-plus-review situation, and we’ll walk you through exactly what the city wants to see. That’s the kind of local knowledge you won’t get from a national installer’s call center.

CGI Models & Products We Service in Austin

We service the full CGI residential line across Austin: the ImpactGuard series windows and doors, Estate Collection impact-rated entry doors, Classic Series single-hung and casement windows, and the 800 Series sliding glass doors. Our parts approach is simple: genuine CGI glazing beads, rollers, weatherstripping, and impact glass units whenever possible, because aftermarket components often don’t meet the same missile-impact ratings. For fasteners and flashing, we source high-grade corrosion-resistant equivalents that exceed CGI’s specs, since Austin’s moist summers and clay soil accelerate rust faster than most manufacturers’ default hardware can handle.

What drives the number up or down? Foundation movement, framing squareness, whether we’re reframing rotted sills, and permit requirements in the recharge zone all move the figure.
