CGI Construction in Houston, TX | Penhallow Remodeling Houston
We’re Penhallow Remodeling Houston, a General Contractor - Houston team providing independent CGI construction service across Houston, Katy, The Woodlands, and every neighborhood in between. What makes our CGI work different here isn’t a factory badge or a marketing line. It’s that we’ve pulled CGI windows and doors out of houses that have been lifted 14 inches above a new floodplain, re-set them, and made them seal tight again. Most contractors in this city have never done that once. We do it regularly. Call (254) 527-5340 and we’ll give you a straight answer on your CGI project.
Why Houston Residents Choose Us for CGI Service
Houston homeowners don’t call us because they want a generic window contractor. They call because a CGI Targa sliding door seized after a flood, or a CGI Estate window started fogging from Gulf humidity, or a foundation re-level left a north-facing frame binding against the brick veneer. Those are the calls Trevor Nash built this crew to answer. Trevor studied construction technology at Los Angeles Trade-Technical College, spent years swinging a hammer on tract homes and full gut-renovations, and has been serving Houston long enough to know that the clay soil near Meyerland moves more than most people think. When you call, you get a written price before any work starts, a real arrival window, and our 365-Day Done Right Promise in writing. If it’s not done right, we come back and make it right. No charge, no argument. That’s how we’ve always operated.
We’re an independent CGI service provider. We are not factory-authorized, and we don’t pretend to be. What we are is deeply familiar with CGI’s product lines: Estate Collection, Targa Series, Classic Series, Sentinel Series. We know which seals fail first, which rollers bind after silt exposure, and which aftermarket structural hardware actually holds up to Houston wind codes. Our CGI sales & service work covers the full range, and we stand behind our labor with our own written guarantee, not a warranty pass-through to the manufacturer.

Common CGI Construction Problems We Solve in Houston
Here are the five failure modes we see most often on CGI products in this specific climate. Each one ties directly to how Houston homes are built, and how this weather treats them.
- Leaking at sill corners on impact-rated windows after house lifts and foundation re-levels. When a slab moves on expansive clay, or when a crew raises a structure to meet post-Harvey flood elevations, the original sill geometry shifts. The corner seals on CGI impact windows don’t flex forever. We re-flash, re-shim, and re-seal so the corner doesn’t weep into the wall cavity during the next heavy rain.
- Fogging between panes on CGI insulated glass units. Houston’s humidity is relentless. Once the desiccant inside an aging CGI IGU gets overwhelmed, condensation forms between the panes and never clears. You can’t just wipe it off. The unit needs to be replaced, and we handle that with OEM glass when lead times allow.
- Seized or binding rollers on CGI sliding glass doors after flood silt infiltration. This is the Meyerland and Kingwood problem. Floodwater carries fine silt into the lower track, and once it dries, the rollers cement themselves in place. We pull the panels, clean or replace the rollers, and re-set the track so the door actually slides again.
- Warped framing at north-facing CGI windows on older brick veneer homes. North-facing walls on 1970s and 80s tract homes don’t get the sun’s drying heat, so moisture lingers. When slab movement transfers pressure through the brick veneer, the window frame takes the load. We see bowed jambs and stressed corner welds. Sometimes it’s a repair; sometimes the frame is too far gone and replacement is the honest answer.
- Failed hurricane strap tie-ins and elevated sub-sill connections. After a house lift, the original tie-in points don’t always align with the new elevation. We replace factory connections with tested aftermarket structural hardware that actually meets current wind load requirements for the Houston market.
CGI Service in Houston: What Local Conditions Mean for Your Equipment
Here’s something that shows up in Houston and almost nowhere else in Texas. After Hurricane Harvey, FEMA redrew the floodplain maps, and a lot of Houston’s residential flood zones now reference the 500-year flood level. That elevation, not the original slab height, is what determines where impact-rated windows and doors must sit on a raised house. This spec does not apply in Pearland. It doesn’t apply in Sugar Land. It applies here, in Houston, to any property that falls inside the new floodplain boundaries. What that means for your CGI equipment is simple. If your windows were installed before the maps changed, they may be too low relative to the current FEMA elevation. That isn’t a cosmetic issue. It affects how water drains away from the sill, how flashing details perform, and whether the unit will pass inspection if you ever sell. When we set CGI windows on a raised or re-leveled Houston home, we anchor them to the new flood elevation, not the old one. It’s the difference between a window that looks right and one that actually stays dry.
On a pier-and-beam bungalow in Meyerland, our crew handled our Bathroom Remodeling in Houston expertise to remove a CGI Targa sliding door that had seized shut after flood silt packed the lower track. We re-set the frame with a pressure-treated, shimmed sub-sill positioned 14 inches above the new FEMA flood elevation. We replaced the rollers with OEM parts, re-hung the panels, and the door cleared the house’s re-leveled floor with no binding and no leak at the sill. That’s the kind of repair you only learn how to do by doing it in Houston, on Houston houses, with Houston’s flood history standing right there next to you.
CGI Models & Products We Service in Houston
We service the full CGI residential lineup that shows up in Houston homes. The Estate Collection, built for coastal impact zones and seen on higher-end builds throughout the Houston area. The Targa Series, which is what you’ll find on a lot of mid-2000s suburban construction. The Classic Series, common on older tract homes from the 1990s. And the Sentinel Series, the value-line option that still gets hit with the same humidity and clay-soil movement as its more expensive siblings.
Our parts approach is straightforward. We default to OEM CGI seals, rollers, and balance systems when delivery times fit the repair window. That keeps the window operating exactly as CGI designed it. But for hurricane strap tie-ins, elevated sub-sills, and structural connections, we use tested aftermarket hardware that meets or exceeds current Houston wind code requirements. If the frame or glazing itself has been compromised by repeated flood exposure or foundation shift, we’ll recommend replacement. Not because it’s easier for us, but because a patch won’t hold to wind codes, and you deserve a straight answer on what the repair actually costs versus what it’s worth. We stock common CGI-compatible hardware locally for faster Houston turnaround, and anything that needs to be ordered gets ordered the same day we diagnose it.

AfterCGI Service Pricing in Houston
The cost of CGI construction work in Houston depends on what you’re actually doing. A window replacement on a single unit costs far less than a full home addition that includes impact-rated openings. Here are the ranges we quote most often for Houston homeowners:
| Service | Houston Price Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Roof Replacement | $8,000 – $20,000 |
| Home Addition | $45,000 – $130,000 |
What moves the number up or down? For impact windows, it’s the number of openings, whether the frames need re-flashing or full tear-out, and whether you’re dealing with a standard slab home or a raised pier-and-beam structure that needs elevated sub-sills. For roof replacement, it’s the square footage, the decking condition, and whether we’re tying in new hurricane straps while the sheathing is open. For a home addition, layout complexity and foundation scope drive most of the variance. Every estimate we write is a fixed, line-item number before work starts. The number on day one is the number on the invoice. Call (254) 527-5340 to schedule a free estimate, and we’ll put it in writing.

FAQs – CGI Construction in Houston
Yes. When a house has been lifted or re-leveled to meet post-Harvey FEMA elevations, the original flashing details no longer line up with the new sill heights. Water doesn’t care that the window used to be fine. We install elevated sub-sills and re-flash corners to drain properly at the new height. If your house was raised and your windows weren’t re-flashed, this is worth checking before the next big rain. Call (254) 527-5340 and we’ll take a look.
Yes, in most cases. Discontinued doesn’t mean unobtainable. We can often source exact-size CGI Estate glass packs and hardware through our supplier network, even when the original line item is no longer in production. When an exact match isn’t available, we’ll give you the closest compatible option and a written price on both before you decide. Estimates are free.
Not necessarily. If the door was submerged for a day or less, the rollers and track can often be cleaned, replaced, and re-lubricated so the door operates correctly. The panels themselves may be fine. What we look for is frame distortion, delamination, or water intrusion into the wall cavity behind the jamb. If the frame is twisted or the glazing has separated, replacement is the right call. If it’s just silt and seized rollers, it’s a repair. We’ll tell you which one you’re dealing with and what each costs. Call (254) 527-5340 for an exact quote.
CGI frames are rigid, which is good for impact resistance but means they transfer stress directly to the frame corners and the surrounding opening when the slab shifts. On Houston’s expansive clay, that stress shows up as leaking sill corners, binding sashes, or hairline frame cracks at stress points. The fix depends on how much movement has occurred. Sometimes it’s a re-shim and re-seal. Sometimes the frame has twisted past where a repair will hold. We measure, we level, and we give you the straight number for whatever the fix requires.
No. CGI’s manufacturer warranty covers their product, not the labor performed by an independent service provider like us. That’s why we back our labor with our own written guarantee, the 365-Day Done Right Promise. If our repair fails inside a year, we come back and fix it at no charge. You get the OEM part where it matters, and you get our labor guarantee regardless of what CGI’s fine print says. Call (254) 527-5340 and we’ll walk you through exactly what’s covered before you spend a dollar.
