CGI builds its reputation on impact-rated aluminum and vinyl windows and doors. In Houston, that matters. The city sits in a hurricane zone, and homes from Clear Lake to Katy routinely take wind-driven rain, salt air, and summer heat that punishes cheap hardware. But even the best-built CGI window eventually needs a balance replaced, a lock freed, or a glazing bead re-seated. That’s where CGI service in Sugar Land and across Houston comes in. Westlight Windows Houston is an independently owned and operated Kingswell location, founded in 2009, and we install and service eight manufacturer lines including CGI, PGT, CWS, ES Windows, and ECO Window Systems. We are not an authorized CGI dealer, and we don’t pretend to be one. What we are is a Houston-based crew that knows these products well enough to fix them right and tell you honestly when a repair no longer makes sense.

Why Trust Westlight Windows Houston for Your CGI Windows & Doors?

Owen Satterfield, our owner, learned the trade at Los Angeles Trade-Technical College and has been measuring, ordering, and installing windows and doors for close to two decades. He has worked on Houston homes from the older bungalows in the Heights to new construction near CGI Windows & Doors in The Woodlands, TX. His crews keep manufacturer spec sheets on hand and actually read them before quoting a job, because a CGI Sentinel has different corner joinery than a Targa, and guessing on an impact-rated frame is how you get a failed inspection or a leaking wall.

When we service a CGI product, we’re working within an existing engineering envelope, not improvising. That means the glazing bead profile has to match the extrusion, the balance has to carry the correct sash weight, and the weatherstripping has to compress within the manufacturer’s tolerance. If a part doesn’t meet that standard, we say so and find one that does. The Kingswell Guarantee backs every job: a written price before any work starts, a committed arrival window, a clean job site, and a written guarantee on the completed work. If a repair fails within the guarantee period, we come back and correct it at no charge. No fine print, no arguing.

Common CGI Windows & Doors Problems We Fix in Houston

• Failing compression glazing beads on older CGI Estate windows. The Estate series uses a compression-style bead to hold the insulated glass unit in place. After years of Houston humidity and heat cycling, the vinyl bead can lose its memory and pull away from the glass, letting water sit in the glazing channel. We see this often on Estate windows from the mid-2000s. The fix is a proper re-set with the correct bead profile, not a tube of silicone smeared over the joint.
• Corroded cam locks and keeper hardware on CGI sashes near the bay. Salt air from Galveston Bay travels farther inland than most people think. Homes in Clear Lake, Seabrook, and even League City get marine corrosion on exposed hardware. The cam lock on a CGI single-hung or casement can seize, and eventually the keeper plate gets pitted enough to break. We replace these with OEM or marine-grade stainless aftermarket locks that hold up better in coastal air.
• Frame corner stress fractures on CGI Sentinel windows in homes with slab settling. Houston has expansive clay soil. When a slab shifts, window frames get racked. The Sentinel series is tough, but a corner weld can develop a hairline crack under enough racking pressure. That crack becomes an air leak, then a water leak. Sometimes the frame needs full replacement; in early cases, the joint can be reinforced and re-sealed properly.
• Worn or brittle vinyl weatherstripping channels on CGI horizontal sliders. After ten to fifteen years of Houston sun, the vinyl pile or fin weatherstripping in a CGI slider becomes brittle and compressed. The window still looks fine, but it no longer seals. You’ll feel a draft in winter or see your cooling bill creep up in August. Replacing the weatherstripping is a straightforward job when you have the right profile on hand, which we do.
• Sheared sash balances on CGI single-hung impact windows. The balances carry the weight of a heavy laminated impact sash every time you open the window. Over time, the bushings wear, the spring weakens, and one day the sash won’t stay up or won’t close at all. We stock heavy-gauge stainless balance replacements specific to Sentinel and other CGI series, so this repair is usually same-visit once parts are confirmed.

CGI Parts & Our Repair-vs-Replace Approach

For CGI structural components, especially impact-rated glazing and frame members, we use OEM parts whenever they’re available. Impact-rated products are engineered as a system, and substituting a non-rated laminated glass unit or a different frame extrusion defeats the product’s tested performance. That’s not a corner worth cutting. For hardware like cam locks, keepers, handles, and weatherstripping, we often recommend quality aftermarket alternatives when they outperform or outlast the original. In Houston’s salt air, a marine-grade stainless lock can be a better long-term choice than the original pot metal part.

We’re honest about repair versus replace. If we’re replacing a balance and a lock, the repair makes obvious sense. If the frame is racked, the glass is failed, the weatherstripping is gone, and the window is twenty years old, you’re better off putting that money toward our Window Replacement services rather than chasing one problem after another. We’ll lay out both numbers and let you decide. Call (325) 326-4211 and we’ll give you a written price before any work begins.

Our CGI Service Process – Step by Step

1. 1
   Diagnosis. We start by identifying the exact failure. On a CGI impact window, that means checking the laminated glass for cracks, inspecting the bead and glazing channel, testing the balance, and looking at the hardware under load. Crucial detail: we match the product’s series, because a Sentinel is not an Estate neither in profile nor in part numbers.
2. 2
   Parts matching. Once we know the failure, we match the correct OEM or aftermarket part. For structural glazing and frame components, that’s OEM. For hardware and weatherstripping with a better aftermarket option, we tell you what it is and why we recommend it, then quote both.
3. 3
   Repair or replacement. We perform the repair with the sash removed where needed, cleaning out old sealant and degraded bead. If we’re doing a full frame replacement, we remove the existing unit, inspect the rough opening, and correct any water damage or rot before installing the new CGI product.
4. 4
   Testing and adjustment. Every serviced window gets a function test: lock engagement, balance travel, seal compression, and a water spray test where water intrusion was the original complaint. If it doesn’t pass, we keep working until it does. That’s the standard, not an aspiration.
5. 5
   Warranty and documentation. You get a written guarantee that covers the work. If that repair fails within the guarantee period, we return at no charge. Our 365-Day Done Right Promise means what it says: if it’s not right, we make it right.

CGI Products We Service & Install in Houston

We work on the CGI Sentinel Series, Estate Series, Targa Series, and CGI Custom Impact Windows and Doors. That includes single-hung and horizontal slider Sentinels, Estate casements and fixed picture windows, Targa with its narrower sightlines, and custom impact door systems from CGI’s architectural line. We stock balances, cam locks, keeper hardware, weatherstripping profiles, and glazing bead for the most common CGI series found in Houston homes. For Houston specifically, that means Sentinels and Estates dominate, since those were the volume products installed across the metro over the past two decades.

On the installation side, we handle hurricane impact windows, full frame replacement, and insert window replacement for CGI products. An insert replacement preserves your existing CGI frame when it’s structurally sound; a full frame replacement is the right call when the frame itself is compromised.

We Also Service These Brands

CGI isn’t the only line we carry. We install and service PGT, CWS, ES Windows, and ECO Window Systems, among eight total manufacturer lines. If you have a mixed home, where some windows are CGI and others are PGT, we can handle both under one visit and one written estimate, so you’re not coordinating two contractors and two warranty processes.
