CGI Windows & Doors: The Houston Owner’s Guide
If you own a home in Houston with CGI windows or doors and a part has failed, here’s the straight answer: we can source the correct CGI-compatible component, install it, and stand behind the work with our 365-Day Done Right Promise. Depending on what failed, a typical parts-and-labor repair runs between $400 and $1,800 in Houston, with full window or door replacement landing in the $8,000 – $25,000 range. Most owners discover the failure the same way: a window that won’t lock, a door that drags against the frame, or a seal that’s gone cloudy in the Houston humidity.
The first question we always ask on these calls is whether the problem is the part or the installation. Half the time, a CGI window or door that feels “broken” is actually a hinge that’s drifted out of adjustment, a roller that’s clogged with silt, or flashing that was never lapped correctly. Our techs will tell you which one it is before quoting anything, because the difference between a $12 roller and a $1,200 sash replacement matters. We’re an independent service provider, not affiliated with CGI, but we work with their product lines every week in this market.
Key Takeaways
- CGI parts failures in Houston are most often rollers, hinges, worn weatherstripping, or delaminating insulated glass units.
- We diagnose first, price in writing, and never sell a replacement where a rebuild will do.
- Every repair is covered by our 365-Day Done Right Promise: if it fails inside the guarantee period, we come back and fix it at no charge.
- Call (254) 527-5340 and you’ll reach a live person, not a voicemail maze.
Which CGI Models This Applies To

CGI builds a handful of lines that show up regularly in Houston homes, and the compatibility gotcha is that parts are not universal across them. The high-end impact-rated lines — the ones spec’d for coastal wind zones — use heavier extrusions and different hardware than the non-impact architectural series. A roller that fits a standard CGI sliding door will not necessarily carry the weight of an impact-rated panel. The same goes for hinge sets and multipoint lock bodies. Before you buy anything, match the part to the specific series, not just the brand name.
Here’s the practical way to identify what you have. Look for a small label on the edge of the door panel or window sash — it typically carries a product code, series designation, and sometimes the date of manufacture. If the label is gone (sun and humidity in Houston will eventually eat most of them), measure the stile width and the hardware footprint. Impact windows will have a visibly thicker frame profile, usually 3-1/4 inches or more. Impact doors are noticeably heavier when you lift the panel. We match parts to those measurements, which is why we prefer to put eyes on the unit before ordering anything.
On the OEM-versus-aftermarket question: for load-bearing parts like hinges, rollers, and locking hardware, we spec OEM CGI where the product is still in production. For consumables — weatherstripping, sweeps, glazing beads, screen spline — a good aftermarket equivalent saves real money and performs identically. We’ll tell you which bucket your part falls into and price it honestly. We also keep common CGI hardware on the truck for service calls across Houston, because nobody wants to wait a week for a door that won’t close.
Styles & brands we work with







Signs Your CGI Windows & Doors Is Failing
- The door drags or needs a hip-check to close. In nine cases out of ten this is a roller failure, and in Houston the cause is almost always fine silt working into the bearing. It starts as a grind, becomes a drag, and eventually the roller seizes and the track gets scored.
- Condensation between the glass panes. That’s a failed insulated glass seal. Once the desiccant inside the spacer is saturated — and Houston’s humidity accelerates this — the unit fogs and the thermal performance drops. The fix is a new IGU, not a sealant repair.
- The lock feels loose or won’t fully throw. Multipoint lock bodies on CGI doors involve a gear-train inside the panel. When one gear strips, the whole system feels sloppy. It’s repairable, but the longer it runs misaligned the more wear it puts on the keepers in the frame.
- You can see daylight or feel air moving at the weatherstrip. Houston’s heat breaks down foam and vinyl weatherstripping faster than most people expect. When the seal compresses permanently, you lose the airtight fit the door was designed for — and your AC bill quietly picks up the difference.
- The panel rattles when the wind gusts or the hinges squeak under load. Loose hinges or worn hinge bushings let the panel drop a few millimeters. That misalignment then accelerates every other wear point. More than half the hinge replacements we do in the Meyerland and Westbury areas start with a homeowner ignoring a squeak for six months.

AfterReplacement Cost & What’s Included

For CGI parts-and-labor repairs in Houston, expect to pay roughly $400 to $1,800 depending on what failed. A roller set replacement runs $400 – $600 installed. Weatherstripping and sweep replacement lands around $250 – $700. A multipoint lock body is $600 – $1,200. An insulated glass unit, which has to be ordered to spec, typically runs $800 – $1,800 installed. If the frame itself is compromised or you’re replacing the entire unit, full window replacement ranges $4,500 – $15,000 and full impact window installation can run $8,000 – $25,000.
What drives the price up or down is mostly three things: whether the part is OEM or aftermarket, whether we’re dealing with impact-rated or standard profile hardware, and whether the surrounding frame or track needs remediation once we open it up. We give you a written price before any work starts — not a range, not a ballpark — and the number on that line is the number on the invoice. Every job carries the 365-Day Done Right Promise in writing: if the repair fails inside the guarantee period, we come back and fix it at no charge. No re-inspection fee, no service call, no arguing about it.
DIY or Call Us?
The honest split is this: you can safely clean a track, tighten a loose handle screw, or replace a weatherstrip if you can match the profile. Those are five-minute jobs with the right part, and we’ll even tell you which weatherstrip to buy if you call. Where DIY goes wrong with CGI doors is anything involving the hinged panel weight. Impact-rated CGI door panels can weigh 200 pounds or more. Pulling a roller out of a loaded panel without the right support block is how people get crushed fingers and broken glass — we’ve seen it go badly, and it’s not worth the $600 you’d save.
The same logic applies to anything involving the lock gear-train or a failed IGU. Those need a trained hand and the right tools, and they’re exactly the kind of job a background-checked, uniformed tech can knock out on one visit. If you’re not sure which bucket your problem falls into, call (254) 527-5340. We’ll tell you straight whether it’s something you can handle or something we should handle.
FAQs

CGI products are built for coastal wind zones and routinely last 20 to 30 years in Houston, but the hardware and weatherstripping wear faster: rollers typically need replacement every 7 to 10 years, and weatherstripping every 5 to 7 in our heat and humidity. The glass itself, if the seal holds, will outlast both.
Rollers, hinges, and lock bodies on CGI units are designed as replaceable components, so repair is usually the right answer — we rebuild rather than replace wherever the part is still sound. The exception is a sealed glass unit with fogging, which cannot be repaired and must be replaced as an IGU. Call (254) 527-5340 and we’ll give you the repair-vs-replace answer over the phone.
A roller, hinge, or lock body replacement is a 45-to-90-minute job from start to finish. A new insulated glass unit takes about the same once the glass arrives, though the order itself usually takes a week to ten days because it’s cut to your exact panel size.
We keep common CGI hardware — rollers, hinge sets, lock bodies, and sweeps — on our trucks and in the shop, so a lot of service calls in Houston are completed same-visit. Specialty items like IGUs and impact-rated panel hardware are ordered to spec, and we’ll give you a clear timeline before you commit to anything. Call (254) 527-5340 for availability on your specific part — the estimate is free.
If your CGI window or door is failing and you want a straight answer on what it costs to fix, call Trevor and the team at Penhallow Remodeling Houston at (254) 527-5340. We’ll schedule a look at the unit, put the price in writing before any work starts, and back the repair with a 365-day promise to make it right. Give us the straight story on what you need, and we’ll give you the straight number on what it costs.
