CGI Construction in Georgetown, TX | Penhallow Remodeling Austin
We provide independent CGI window and door service across Georgetown, from the 1960s ranch homes off Southwestern Boulevard to the new limestone-and-brick subdivisions west of I-35. The one thing that makes our CGI work here different is that we understand how Historic and Architectural Review Commission rules in the Old Town District shape every window decision, and we price accordingly. Trevor Nash and our crew have been swinging hammers in Central Texas for over a decade, and we answer the phone when you call (325) 225-5429.

Why Georgetown Residents Choose Us for CGI Service

We’re not a manufacturer affiliate. We’re an independent CGI service provider, which means we call problems like we see them. If a repair gets you another decade, we’ll say so. If the frame is warped beyond saving, we’ll tell you that too and quote a replacement at a real number. Trevor learned construction fundamentals at Los Angeles Trade-Technical College and has spent years on everything from foundation repairs to full kitchen rebuilds, so when a CGI window binds because the slab shifted, he treats it as a structural problem, not just a sash issue.
Our CGI sales & service work spans the full Georgetown housing mix. We’ve pulled fogged insulating glass from Classic Series units in 1970s ranchers, replaced Sentinel storm windows on 2010s tract homes, and navigated HARC paperwork for Estate Series installs in Old Town. We stock OEM sashes, balances, and weatherstripping where they’re still manufactured, and we keep certified aftermarket options for discontinued lines so you’re not waiting three weeks on a backorder.

Common CGI Construction Problems We Solve in Georgetown
- Fogging and seal failure in older Classic Series glass units. Georgetown’s UV index runs high from May through September, and after 15 to 20 years, that relentless sun plus 40-degree temperature swings breaks down the butyl seals in vinyl-frame units. The result is haze between the panes that won’t wipe clean. We replace the insulating glass unit itself when the frame is still sound.
- Sticking or binding single-hung sashes in 1960s and 70s ranch homes. Central Georgetown sits on expansive clay that swells with spring rain and shrinks during drought. Foundations move, rough openings skew, and a sash that worked fine for 40 years suddenly won’t budge. We re-shim the frame and, where needed, replace the balance system rather than forcing the window.
- Weatherstripping degradation on Sentinel storm windows. Limestone-laden water from the Edwards Aquifer leaves hard mineral and dust deposits that eat away at gaskets and compression seals. Once the weatherstripping loses its give, impact-rated windows lose their storm-seal performance. We replace strips with OEM or matched-density equivalents.
- Vinyl frame warping on south-facing windows in unshaded subdivisions. Newer neighborhoods south of Williams Drive often have minimal mature tree cover, and attic temperatures in these homes exceed 140°F in August. That heat radiates down into the window frame, causing miter joints to separate on CGI Estate and Classic vinyl units. We assess the frame for warping and recommend full replacement when the structural integrity is gone.
- HARC-mandated window changes in the Old Town District. If your home falls under Historic and Architectural Review Commission oversight, you can’t just drop in any replacement unit. Original window dimensions, muntin profiles, and wood-look finishes all matter. We handle the product matching and the paperwork so the review doesn’t stall your project.
CGI Service in Georgetown: What Local Conditions Mean for Your Equipment

Here’s something you won’t find on a generic CGI page. In Georgetown’s Old Town District, the Historic and Architectural Review Commission requires replacement windows to match the original wood dimensions and profile of the home. That means dozens of 1990s-era CGI vinyl windows, installed before the current review standards tightened, now fail HARC review when a homeowner wants a simple swap. You can’t just order a white vinyl Classic Series unit off the shelf. You need a wood-look Estate Series window with custom jamb extensions that match the original sightlines, and you need a General Contractor in Georgetown who’s filed enough HARC applications to know what gets approved and what gets kicked back.
We replaced three south-facing CGI Classic Series windows in a 1978 ranch home on Maple Street in the historic district last July. The vinyl frames had miter joint separation from attic heat, and the insulating glass had failed, causing fogging. We installed CGI Estate windows with wood-look interiors and reinforced frames that met HARC guidelines, cutting the homeowner’s summer cooling load by nearly 20 percent. That’s the kind of local knowledge that changes the scope and the price of a job before we ever write the estimate.
CGI Models & Products We Service in Georgetown
We service the CGI lines you actually see in Georgetown, not a catalog list. The Classic Series single-hungs and picture windows show up everywhere in 1960s through 80s ranch homes. The Sentinel Storm Protection series is standard in newer suburban subdivisions with impact-rating requirements. The Estate Collection, with its wood-look vinyl, is the go-to for Victorian and Craftsman-era Georgetown Bathroom Remodeling and other historic home projects in the downtown core. And the Commercial Series heavy-gauge aluminum storefronts turn up in downtown retail conversions around the 1911 courthouse square. For discontinued models, we source certified aftermarket glass and hardware that match the original Energy Star ratings, so you’re not stuck with a dead window and no path forward.

What drives a window job in Georgetown is the condition of the rough opening, the window count, and whether HARC review applies. A straightforward three-window replacement in a 2000s tract home lands on the low end. A full-home window swap in Old Town with custom jamb extensions and historical review lands higher. Our free estimate puts a specific number in writing before any work starts, and that number stays the number on the invoice. Call (325) 225-5429 and we’ll come walk the house.

FAQs – CGI Construction in Georgetown
In most cases, yes. If the frame is square and the vinyl hasn’t warped, we can replace just the insulating glass unit. We use OEM glass when available, or certified aftermarket units that match the original Energy Star rating. This typically saves you 60 to 70 percent compared to a full window replacement. But if the miter joints have separated or the frame has bowed from Georgetown heat, glass-only becomes a short-term fix. Call (325) 225-5429 and we’ll tell you which one your window actually needs.
Georgetown isn’t a coastal hurricane market, so impact-rated windows aren’t about storm surge. What Sentinel windows do here is reduce wind-driven debris risk during spring supercells and, more practically every day, improve the thermal envelope. Impact glass blocks more UV and lowers cooling load in our August heat. If your home is in a newer subdivision with HOA impact requirements, the choice is made for you. If not, we’ll help you weigh the cost honestly.
HARC reviews any exterior change to contributing structures in the Old Town District. For windows, that means dimensions, muntin pattern, and profile must match the original. Vinyl windows installed before the current standards often fail review today. We specify wood-look Estate Series units with custom jamb extensions to satisfy code and historical review, and we submit the application for you. Budget several weeks for the review process in Georgetown. Call (325) 225-5429 and we’ll check your property’s HARC status during the estimate.
Fogging between panes means the insulating glass unit’s seal has failed. Once the seal goes, the argon or krypton fill escapes and condensation forms between the lites. It’s not a cleaning issue. In Georgetown, 15 to 20 years of UV exposure and wide temperature swings will break down the butyl seals on older Classic Series units. The fix is replacing the IGU, not the whole window, in most cases.
Yes, and this is where we spend real time during the estimate. We match the frame color, grid pattern, and sightlines to the original units. For 1970s ranchers, that’s usually a Classic Series single-hung with a consistent three-over-one lite pattern. If the original line is discontinued, we source a wood-look or white vinyl match that reads the same from the street. Call (325) 225-5429 for a free, written estimate.
