CGI Windows & Doors: The Houston Owner’s Guide
If you own CGI windows or doors in Houston, you already know they’re built for impact, which means they’re also built to very tight tolerances. We stock and install CGI-compatible replacement parts, with most window and door service calls running between $400 and $2,500 installed depending on what failed. The typical call we get starts the same way: a sash won’t close flush after a storm, a hinge is grinding, or a seal started fogging between the glass panes. You notice it in the wet season first because that’s when Houston humidity finds every weak point in an opening.
Bradford Remodeling Co Houston is an independent service provider. We are not affiliated with CGI, but we work on their products regularly because Houston homes built to coastal and wind-borne debris standards use them heavily. That work has taught us exactly what fails, what to stock, and what the OEM charges versus what a quality aftermarket equivalent actually costs.
Which CGI Models This Applies To
CGI produces several lines that show up in Houston homes. The most common we service are the Estate Collection, the Targa Series, and the older Sentinel Series impact windows and doors. Estate models are aluminum-framed with heavy multi-point lock hardware. Targa units are also aluminum but with a narrower profile and a different hinge assembly. Sentinel is the legacy line we still see on homes built in the 1990s and early 2000s, and parts for those are getting harder to source as an OEM item.
The fastest way to identify the right part is the sticker on the frame or the etching in the corner of the glass. CGI marks their units with a manufacturing code that includes the series designation and the production date. If that sticker is gone, measure the visible glass width and the frame depth in millimeters. A Targa hinge will not mate to an Estate sash even if the width looks close. This is the single most common ordering mistake we correct: an owner buys a hinge or a roller assembly online, it arrives, and the bolt centers are off by 4mm. For CGI, spend the extra two minutes confirming the series before you spend money.
On OEM versus aftermarket: CGI’s factory parts are well made but priced at a premium, and some legacy Sentinel components are now 8 to 12 weeks out from the factory. For seals, weatherstripping, rollers, and certain hinge inserts, a quality aftermarket equivalent from a supplier that specializes in impact-rated fenestration will perform as well and cost 40% to 60% less. For lock bodies, multi-point hardware, and anything structural, we recommend OEM. The stakes are too high on a door that’s supposed to hold in a hurricane.

Signs Your CGI Windows & Doors Is Failing
- The sash binds or scrapes when you open or close it. On CGI aluminum frames, this usually means the roller assembly has worn flat or the hinge insert is wallowed out. Houston’s humidity accelerates corrosion on the steel roller pins.
- Condensation you can’t wipe away, between the panes. This means the insulated glass unit seal has failed. CGI units use a dual-seal system, and once the inner seal goes, the argon or krypton gas escapes and the glass loses its thermal performance.
- The multi-point lock takes two hands and a knee to throw. The lock rod is out of alignment, usually because the door panel has settled or the keepers on the jamb have shifted. Forcing the handle bends the rod, and now you need both the rod and the handle assembly.
- Water stains on the interior sill or drywall below the window after a rain. The weep system on CGI frames can clog with Houston pollen and dust. Once the weeps are blocked, water backs up in the track and finds the path of least resistance, which is usually into your wall cavity.
- A draft or a whistle when the wind blows from the south. The weatherstripping has compressed and lost its rebound. On a window rated for wind-borne debris, a gap at the seal defeats the point of owning the window in the first place.

AfterReplacement Cost & What’s Included
In Houston, the installed cost for CGI parts and service breaks down like this:
- Roller or hinge replacement on a window: $180 – $400 installed, including the part, cleaning the track, and adjusting the sash so it seats square.
- Weatherstripping and seal replacement: $150 – $350 per opening, depending on whether it’s a window or a full-height door and how much of the jamb seal must be pulled and replaced.
- Insulated glass unit replacement: $450 – $900 per sash for standard sizes. Larger or impact-laminated units push toward $1,200. This is parts-heavy; the labor is typically 90 minutes or less.
- Multi-point lock replacement on a CGI door: $400 – $750 installed. The OEM lock body is the bulk of that number, and we set the keepers so the door locks with one hand, the way it did when it was new.
- Full sash or full panel replacement: $800 – $2,500 depending on the CGI series, glass package, and whether the frame itself is square enough to reuse.
What drives the range is the series. Targa parts cost less than Estate parts, and Sentinel parts now carry a scarcity premium if you need original hardware. Every estimate we give is a written line-item price before we touch the window, and that price does not move at the door. The work is covered under our 365-Day Done Right Promise: if the part or the installation fails within a year, we come back and make it right at no charge.
DIY or Call Us?
Here’s the honest split. Cleaning the tracks, clearing the weep holes, and tightening a loose handle set screw are all reasonable homeowner jobs. A can of compressed air and a soft brush solve half the “stuck window” calls we get. But when you’re dealing with the tensioned hinge assemblies on a CGI window, or the multi-point lock rods inside a Targa door panel, the risk shifts. These doors weigh more than a standard entry door, and a panel that slips while you’re pulling a hinge can take fingers or worse. The glass pack alone on some Estate units runs over 100 pounds. If the job involves lifting a panel off its hinges, spring-loaded hardware, or anything where a misstep means a falling sash, call us at (940) 289-7658. One honest paragraph is all the warning this needs.
FAQs
A properly installed CGI window or door in Houston should deliver 25 to 35 years of service on the frame and hardware, with the insulated glass unit typically needing replacement at the 15 to 20 year mark. Houston’s combination of heat, humidity, and salt-laden air near the coast shortens glass seal life compared to inland Texas. A unit that’s fogged at year 12 isn’t defective; it’s normal for this climate. Call (940) 289-7658 and we’ll confirm whether your glass unit is worth replacing or if the frame is telling you it’s time for a full swap.
Yes, in most cases. Rollers, hinges, weatherstripping, lock hardware, and even the insulated glass unit are all replaceable parts on CGI windows and doors. The only time we recommend replacement is when the frame itself is corroded through, bent from an impact, or so far out of square that new parts won’t seat correctly. That’s maybe one call in fifteen. For a written quote on which way yours goes, call (940) 289-7658.
Most roller, hinge, seal, and lock replacements are done in 90 minutes to 3 hours. Insulated glass unit replacements are ordered to spec and typically installed within 7 to 10 days of the order. We tell you the timeline before we start, and it’s on the written estimate so there’s no surprise on scheduling. Call (940) 289-7658 for a straight answer on your specific unit.
We keep the common failure items on the truck: rollers, hinge inserts, weatherstripping profiles, and lock hardware for Estate, Targa, and Sentinel series. Insulated glass units and full replacement sashes are custom-ordered per unit, because the dimensions are specific to your opening. If your part is something we don’t have on board, we’ll tell you the lead time and the exact cost before we order anything. That’s how Curtis Lane runs every job, straight scope, straight number, that’s the whole conversation. Call (940) 289-7658 to get yours started.
