CGI Construction in Irving, TX | Penhallow Remodeling Dallas
We provide independent CGI service across Irving, from Sentinel Series impact windows to Classic Rib metal roofs. The difference here comes down to dirt: Irving’s expansive clay soils and aging cast-iron plumbing lines create failure patterns on CGI products that you won’t see in most of the metroplex. Call (940) 204-5368 for a straight diagnosis and a written price before we pick up a tool.
Penhallow Remodeling Dallas is a General Contractor in Irving with a dedicated CGI exterior and interior crew. We work on CGI roofs, windows, and trim across Irving’s 1960s-1980s slab homes and older apartment complexes. We’re an independent CGI service provider, not a manufacturer-authorized shop, which means we assess the whole house, not just the window. Our techs know CGI tolerances and typical failure points under North Texas hailstorms and heaving clay. If you’re in a Hospital District bungalow or a Las Colinas condo, we know what your CGI components are up against.
Why Irving Residents Choose Us for CGI Service

Irving is not a city where you can guess at a repair. The housing stock here is mostly slab-on-grade construction from the 1960s through the 1980s, brick veneer with original cast-iron plumbing underneath. That combination, plus clay soil that swells and shrinks with every wet-dry cycle, puts stress on window frames, door tracks, and roof panels in ways a generic CGI service page never mentions. We do.
Trevor Nash leads our crew. He trained at Los Angeles Trade-Technical College and spent years on foundation repairs and full kitchen gut-outs before bringing his crews to Dallas. He’s the kind of contractor who will tell you a window frame crack is a plumbing leak before he’ll sell you a new window. Give you a number before I pick up a tool, that’s the only way Trevor knows how to start. That’s the standard we hold on every CGI job in Irving.
We also run by the Kingswell Way, which has been around since 2004: a written price before any work starts, a defined arrival window, a clean job site, and a written guarantee on every project. If our CGI repair fails inside 365 days, we come back and fix it at no charge. That’s in writing, every time.

Common CGI Construction Problems We Solve in Irving
- Frame deflection on CGI Sentinel Series windows. Slab-on-grade homes in Irving sit on clay that heaves. When the slab moves, the window opening shifts with it, and you get sash misalignment, air leakage, and corner cracking. We check the slab and the plumbing before we touch the window.
- Roller track binding on CGI Estate Collection patio doors. West-facing exposures on 1970s condos, especially around Las Colinas, take brutal afternoon heat. Thermal expansion binds the rollers, and hail-damaged screen tracks make it worse. We repair tracks and realign door panels rather than selling a full replacement when it isn’t needed.
- Oil-canning and fastener backout on CGI Classic Rib metal roofs. Severe hailstorms, the kind that roll through open areas near Las Colinas, dent panels and loosen fasteners. Oil-canning is cosmetic, but fastener backout leaks. We replace panels per square and re-secure fasteners to spec.
- Corner post splitting on CGI vinyl siding at slab junctures. In older brick-veneer homes, original cast-iron plumbing leaks saturate the soil right where siding meets the slab. The post splits, the siding pulls away, and the real cause is underneath. We fix the drain, then the siding.
- Hail-damaged flashings and closures on CGI roofs and windows. Irving sits in a hail corridor. After a storm, we inspect flashings, screen tracks, and roof closures for impact damage that leads to slow leaks months later. A $400 repair beats a $15,000 roof replacement when caught early.
CGI Service in Irving: What Local Conditions Mean for Your Equipment

In Irving’s Del Rancho and Hospital District neighborhoods, Irving Bathroom Remodeling and CGI impact window and roofing work often begins with a cast-iron waste line diagnosis. The original 1960s slab homes in those areas have corroded cast-iron drains that leak under the foundation. That moisture saturates the expansive clay, and the clay moves more aggressively. Homeowners see hairline cracks at window frame corners or eave lines and assume the CGI window or roof panel itself failed. Our crew knows to check the plumbing before quoting a repair, because replacing a window without fixing the saturated soil underneath means the new window cracks the same way in two years.
Our crew was called to a 1972 brick-veneer home in the Hospital District where a CGI Sentinel Series picture window was binding and showed hairline cracks at the frame corners. We found the slab had heaved slightly and the original cast-iron kitchen drain was leaking beneath that corner, saturating the clay and amplifying movement. We pulled the window, replaced the corroded drain section, repaired the slab pocket, and reinstalled the original CGI sash with new OEM weatherstripping. The window has been operating smoothly since.
CGI Models & Products We Service in Irving
We work on the full CGI lineup that shows up in Irving homes and apartment complexes:
- CGI Sentinel Series impact-resistant windows – sash replacement, weatherstripping, frame realignment, corner crack diagnosis.
- CGI Estate Collection patio doors – roller track repair, hinge adjustment, screen replacement, thermal expansion issues.
- CGI Craftsman vinyl siding profiles – corner post replacement, panel repair, water damage assessment.
- CGI Classic Rib metal roofing panels – hail damage repair, fastener replacement, closure and flashing work.
For structural or impact-rated parts, we use OEM CGI components: window sashes, lock mechanisms, roof panel closures. Aftermarket substitutes often lack the same fit and impact rating for Irving’s storm exposure, so we don’t gamble with them. For cosmetic trim, vinyl accessories, and non-structural flashings, we offer quality aftermarket options with equivalent warranty. And when a CGI window unit exceeds 15 years or has multiple failed seals, we’ll recommend replacement over patching. It’s the honest call, and it usually saves money over repeated repairs.

FAQs – CGI Construction in Irving
How does expansive clay soil in Irving affect my CGI impact windows?
Expansive clay heaves and shrinks with moisture changes, shifting the slab and the window openings above it. That movement causes frame deflection, sash misalignment, and corner cracking on impact windows, even when the window itself is sound. In Irving, this is the most common cause of window binding we see. Call (940) 204-5368 if your windows are sticking, and we’ll check the slab, not just the sash.
Can you repair a CGI Classic Rib metal roof on an older Irving apartment complex without full replacement?
Yes, in most cases. Hail-damaged panels can be replaced per square, and fastener backout can be corrected by re-securing to spec. Full replacement only makes sense when the panel system is beyond its service life or the damage covers most of the roof field. We’ll give you a written repair quote before any work starts. Estimates are free.
Why did my CGI Sentinel Series window crack at the corners on a 1960s slab home?
Corner cracks on Irving’s 1960s slab homes usually trace back to two things: slab heave from expansive clay, and old cast-iron plumbing leaking under the foundation. The moisture makes the clay move more, which twists the window frame. We check the plumbing before quoting a window repair, because ignoring the leak means the crack comes back. Call (940) 204-5368 for a diagnosis that looks at the whole house.
Do you use OEM or aftermarket parts for CGI window repairs in Irving?
We use OEM CGI components for structural and impact-rated parts: window sashes, lock mechanisms, roof panel closures. Those parts carry the fit and impact rating your Irving home needs for storm season. For cosmetic trim and non-structural flashings, we offer aftermarket options with equivalent warranty. We’ll tell you which is which, and why, before you spend a dollar.
What should I expect for a CGI impact window installation on a home in the Hospital District?
Expect an honest conversation first. Hospital District homes sit on 1960s slabs with original cast-iron drains, and if there’s a leak under the corner, we’ll find it before we install. Then you get a written price, a defined arrival window, and a crew in uniform. Installation typically runs $800 to $2,500 per unit depending on size and access. Call (940) 204-5368 for an exact quote.
