CGI Construction in Cedar Park, TX | Penhallow Remodeling Austin
We provide independent CGI window, door, and siding service across Cedar Park, and the short answer is this: most of the work we do here involves replacing fogged original CGI units on 1990s and 2000s slab homes, not repairing them. The combination of Texas Hill Country sun and Cedar Park’s expansive clay soil means original CGI Estate windows and Hinge Series doors often fail in ways that make replacement the smarter financial call. Our crews work these tract-home neighborhoods every week, so we know what aging CGI products do in this specific housing stock.

Why Cedar Park Residents Choose Us for CGI Service

We’re not a CGI dealer and we don’t pretend to be one. That matters more than you’d think. What we are is a General Contractor in Cedar Park that has pulled enough original CGI Sentinel and Estate units out of Cedar Park walls to know exactly how they age here and what’s worth saving versus what’s worth swapping out.
Trevor Nash runs our Austin operation, and he learned construction the old way, swinging hammers and rebuilding foundations before he ever touched a window. He’s the one who will walk your house, look at your existing CGI frames, and tell you straight whether a repair buys you five years or whether you’re pouring money into a unit that should have been replaced three summers ago. We stock OEM glass packs for common CGI Estate double-hung sizes because matching the original frame color and grid pattern on a 1990s Cedar Park home is a detail we refuse to get wrong. And if the OEM lead time is stretching past what makes sense, we’ll say so and use quality aftermarket weatherstripping and rollers where they perform just as well.
Every technician who walks onto a Cedar Park jobsite is background-checked and in uniform. You’ll know who’s at your door before they ring the bell.

Common CGI Construction Problems We Solve in Cedar Park
Here’s what we see most often in Cedar Park homes, and why each one shows up here more than in a lot of other places:
- Fogged or moisture-trapped insulated glass in original CGI Estate windows. Fifteen to twenty-five years of direct Texas sun breaks down the seal on double-pane units, and once that happens the argon leaks out and condensation works its way in. In neighborhoods like Buttercup Creek where most originals date to the 1990s, we’re at the tail end of that window right now.
- Warped or binding CGI Hinge Series outswing doors. Cedar Park sits on black clay that shrinks in summer and swells after rain. When a slab foundation moves even a quarter inch, the rough opening around a hinged door racks out of square, and the door starts sticking at the top corner. We see this constantly on original Hinge Series doors on post-1990s slabs.
- Roller and track wear on CGI sliding glass doors. Fine limestone dust is a fact of life on the eastern edge of the Hill Country. It works into the track, grinds against the rollers, and combined with seasonal humidity swings, it chews through hardware faster than it would in a coastal climate.
- Worn or cracked weatherstripping and dry-rotted wood bucks on CGI Sentinel frames. Homes with irrigation sprays hitting exterior walls or poor drainage near the foundation line are the usual culprits. The wood buck behind the frame rots, the weatherstripping loses its flex, and air starts moving through the gap.
- Amateur repair work from previous owners. Cedar Park grew fast, and plenty of early repairs were done quick and cheap. When we open up a wall or pull a window, we frequently find caulk where flashing should be and shims that have cracked or slipped.
CGI Service in Cedar Park: What Local Conditions Mean for Your Equipment

Cedar Park is almost entirely single-family slab-on-grade construction on expansive black clay. That sentence does more work for your CGI windows and doors than any product brochure ever will. Original CGI windows in 1990s neighborhoods like Buttercup Creek sit in wall openings that have shifted out of square as the clay beneath the slab swelled and shrank over three decades. When we pull an old unit, the jambs are often racked three-eighths of an inch or more. You won’t see that in older Austin neighborhoods built on pier-and-beam foundations, because the framing moves independently of the ground. Here, the whole wall moves together. That means a straight swap, new window into old opening, leaves you with a unit that binds, leaks air, and fails its own weatherstripping within a few seasons. Our crews routinely reframe or shim openings to get a true seal before the new unit goes in. It adds a little labor, and it’s the difference between a window that lasts twenty years and one that fights its own frame from day one.
We replaced four original CGI Estate double-hung windows on a Buttercup Creek home where the owners had been living with recurring fogging and air leaks. The old units came out and the jambs had racked nearly 3/8 inch from clay movement. We squared the openings with new sill plates, installed new CGI Estate Low-E windows with heavier weatherstripping, and flashed the perimeter to match the existing limestone veneer lines as part of our Bathroom Remodeling in Cedar Park standards. The drafts stopped, and the new units aligned perfectly with the surrounding stone and brick.
CGI Models & Products We Service in Cedar Park
We work on the model lines that Cedar Park homes actually have. The CGI Sentinel Series impact windows show up on newer builds and on homes where owners upgraded after a storm, and we handle those regularly. The CGI Estate Collection is the one we see most often in 1990s tract homes, the double-hungs and picture windows that came standard in master-planned communities like Ranch at Brushy Creek. We also service the CGI Commercial/Architectural Series and the Hinge Series doors that are commonly paired with Estate Collection windows on front entries and patio access.
For glass packs and hardware, we recommend OEM for best color and dimensional match. For weatherstripping, rollers, and sealants where lead times run long and you’re not in a coastal impact zone, we use quality aftermarket parts that we’ve tested in the field. If the frame is warped, water-damaged, or past twenty years old, we’ll usually steer you toward full replacement, because the original glazing likely lacks modern Low-E or impact ratings anyway.

FAQs – CGI Construction in Cedar Park
Can you match the original CGI window frame color and grid pattern on a 1990s Cedar Park home in Buttercup Creek? Yes, and this is something HOAs in Cedar Park take seriously. We order OEM glass packs and frames in the original color and grid configuration whenever the product line still supports it. For discontinued colors, we’ll work with you to find the closest match your HOA’s architectural review board will accept.
Do I need impact-rated CGI windows in Cedar Park, or are standard replacement windows enough? Cedar Park is not a coastal impact zone, so impact-rated Sentinel Series windows are not a code requirement for most homes. They become worth considering if you want storm protection, noise reduction, or if your specific HOA or insurance carrier asks for them. Standard Low-E replacements are the more common choice here, and we’ll give you pricing for both so you can decide with the numbers in front of you. Call (325) 225-5429 for exact quotes.
Our original CGI sliding patio door is hard to open after our foundation shifted. Can you repair it or do we need a new door? It depends on how far out of square the opening has moved and whether the frame itself is racked. Some sliders respond to new rollers and a track clean. Many original CGI sliders on Cedar Park slabs have moved enough that the frame is binding, and replacement is the honest fix. We’ll inspect it, tell you which situation you’re in, and give you a written price either way.
Will replacing my CGI windows with new CGI units violate my Cedar Park HOA’s masonry and window aesthetic rules? Most Cedar Park HOAs care about frame color, grid pattern, and exterior material, and they want replacements to match the original look. We’ve done enough work in places like Ranch at Brushy Creek to know the drill. We’ll prep the spec sheet in the format your HOA wants and handle the aesthetic matching as part of the job. If your HOA requires specific documentation, we’ll help you get it filed.
What causes the white haze or moisture between the panes in my Cedar Park home’s original CGI windows? That haze is a failed insulated glass seal. The argon gas between the panes escapes, moisture enters the air space, and the glass fogs or hazes permanently. It’s the most common failure we see in 1990s CGI Estate windows across Cedar Park, and it usually means glass pack replacement or full unit replacement depending on the frame condition. Call (325) 225-5429 and we’ll assess whether you’re a glass-pack candidate or a full-replacement candidate.
