Why Houston Homeowners Choose CGI Construction
We provide CGI repair in Houston, TX, with independent construction, repair, and replacement service specializing in Sentinel, Estate, Targa, and Commercial/Architectural impact window lines. Our crews have worked on CGI products in Meyerland, West University, Katy, and the Energy Corridor long enough to know exactly where these windows fail in Gulf Coast conditions, from seal breakdown on west-facing elevations to track corrosion after repeated heavy rains. We’re not a CGI-authorized rep, which means our repair-or-replace advice is based on what the window actually needs, not what the brand wants us to sell. Call (254) 272-5240 to schedule a free estimate.
Houston’s subtropical climate punishes windows. Intense UV, salt air near the coast, hurricane-driven rain, and the slow movement of expansive clay soil under slab foundations all work against even the best impact-rated glass. A CGI window that performs flawlessly in a showroom in Dallas faces a different reality on a west-facing wall in Sugar Land after five summers of direct afternoon sun. That’s the reality we work with every day, and it shapes how we diagnose, repair, and replace CGI products across the greater Houston area.
Key takeaways:
- Independent CGI service provider, not manufacturer-authorized, so our recommendations are unbiased
- We work on Sentinel, Estate, Targa, and Commercial/Architectural CGI impact window lines
- Houston-specific failure knowledge: clay soil movement, humidity, UV exposure, hurricane wind loads
- Written price before any work starts, every time
- 365-Day Done Right Promise: if it’s not done right, we make it right
Why Trust Elmstead Remodeling Houston for Your CGI Construction?
Graham Stein, our owner, learned the trade at Los Angeles Trade-Technical College and spent the better part of two decades managing crews before bringing that experience to Houston. He’s not a salesperson with a catalog. He’s a contractor who has pulled apart enough failed window frames to know that a fogged CGI Sentinel isn’t always just a seal issue – it’s often the first sign that the frame itself has shifted, and no amount of glass replacement will fix a unit that’s no longer square. That’s the difference between a patch and a proper repair.
Every technician who touches a CGI window on your home is background-checked and uniformed. They arrive with shoe covers and drop cloths, and they don’t start cutting before the floors are covered. We stock OEM-compatible CGI hardware and glass locally in the Houston market, which means a shorter wait on common repairs like balance replacements and roller swaps. When a CGI frame is still under warranty, we recommend sourcing parts directly through the manufacturer’s warranty channel so the impact certification stays intact. When the warranty has expired, we use Miami-Dade certified aftermarket laminated glass that meets the same impact standards, and we tell you exactly what you’re getting before the work starts.
Our service area covers the full swath of Houston: Meyerland, Braeswood, West University, Bellaire, Memorial, the Energy Corridor, Katy, Cypress, CGI in Spring, The Woodlands, and everywhere between. A written price and a covered floor before any work begins – that is where the trust starts.

Common CGI Construction Problems We Fix in Houston
Here’s what we see most often on CGI products in Houston, based on actual service calls:
- Fogging between panes on Sentinel impact units: This is the number one call we get from Houston homeowners with CGI windows. The seal between the laminated glass panes breaks down, and humid air gets trapped inside. On west-facing elevations with heavy afternoon sun, the thermal cycling accelerates the failure. Once moisture gets between the panes, the insulating gas is gone, and the glass needs replacement – no amount of cleaning will fix it from the outside.
- Roller and balance wear on single-hung and horizontal sliders: CGI sliding windows and single-hungs use a system of rollers or balances to keep the sash moving smoothly. In Houston’s humidity, those components corrode faster than the manufacturer’s average expectations, which were likely calibrated for drier climates. A sticky or uneven-closing CGI window is almost always a roller or balance issue, not a frame problem.
- Weep hole clogging and track corrosion: Houston gets about 50 inches of rain a year, much of it in short, intense downpours. CGI frames have weep holes designed to drain water from the track, but they clog with dirt, pollen, and Houston’s fine clay dust. Water backs up, sits in the track, and corrodes the internal hardware. A sill leak on a CGI window is frequently traced back to a clogged weep hole, not a failed seal.
- Stress cracks at corner welds on larger Estate picture windows: We see this most in homes built on Houston’s expansive clay soils. The slab moves, the wall framing shifts, and a big fixed picture window that can’t flex with the structure develops hairline cracks at the welded corners. CGI Estate picture windows are well-built, but no welded corner is designed to absorb the racking forces of a foundation that moves seasonally. When we see corner cracks, we check the frame for square before we touch the glass, because replacing the glass in a racked frame just means another crack in six months.
- Impact glass delamination in older Targa units: Impact windows are made from two layers of glass bonded to a plastic interlayer. Over time, especially with constant Houston heat and UV, the edges of that laminate can start to peel or cloud near the frame. It weakens the impact rating and looks bad from the inside. The fix is a new sash or, depending on the age, a discussion about whether a full replacement is smarter.
CGI Parts & Our Repair-vs-Replace Approach
When a CGI window fails, the first question is whether the frame is still square and the sash is still structurally sound. If it is, we repair with OEM parts whenever possible. For CGI windows under factory warranty, we source through the manufacturer’s channels so the impact certification label stays valid, and we’ll help you navigate the warranty paperwork rather than leaving you on hold with a call center. When the warranty has expired, we use comparable Miami-Dade certified aftermarket laminated glass and hardware. These meet the same structural standards and often arrive faster than OEM orders, which matters when you’re looking at a boarded-up opening before hurricane season peaks in August.
But we’re also honest when a patch doesn’t make sense. On load-bearing mullion assemblies where multiple CGI windows are joined together, a single pane replacement on a compromised frame is a waste of your money. We’ll tell you that, show you why on-site, and quote a full frame replacement instead. The goal isn’t to sell you more; it’s to leave you with windows that actually work in Houston’s conditions. Call (254) 272-5240 and we’ll walk the job with you before you commit to anything.
Our CGI Service Process – Step by Step
- 1
Diagnosis and written scope: A technician arrives with shoe covers on, inspects the CGI window, and checks frame square with a level before anything else. We identify the exact failure – seal, roller, balance, weld crack, track corrosion – and write a line-item scope with a fixed price. That written price is given to you before a single tool comes out of the truck, and it doesn’t change unless you approve a change order.
- 2
Parts sourcing and scheduling: If OEM parts are needed for a warranty-covered CGI window, we order them and schedule the work around Houston weather, not the other way around. If we’re using aftermarket parts, we confirm specs and lead time the same day. You’ll know the schedule and the cost before we start.
- 3
Repair or replacement install: Drop cloths go down before any cutting or glass removal begins. We use quiet tools during family rest hours where possible, and we ask before moving anything near the work area. For impact-rated CGI units, we maintain the structural seal and flange integrity so the window’s wind-load rating stays intact.
- 4
Testing and certification check: After the install, we operate the window through its full range of motion, check the seals, verify weep holes are clear, and make sure the sash locks properly. For impact windows, we confirm the frame is square and the unit sits true in the opening, because a racked install will fail the same way the original did.
- 5
Clean-up with photo proof: We clean the work area, vacuum any debris, and take a photo of the clean-up before the crew leaves. You get that photo as part of the job record. The 365-Day Done Right Promise covers the completed work: if it’s not done right, we make it right.

AfterCGI Products We Service & Install in Houston
Our Houston crews work across the full CGI residential and commercial impact window lineup. That includes CGI Sentinel Series Impact Windows, which are the brand’s most common residential line; CGI Estate Collection Impact Windows, including large picture units and casements; CGI Targa Series Impact Windows for sliding and architectural applications; and CGI Commercial/Architectural Impact Windows, which we’ve serviced in Houston high-rise and mid-rise buildings. Locally, we stock common balance systems, roller assemblies, and weatherstripping that fit these lines, so common repairs don’t wait on long manufacturer lead times.
We Also Service These Brands
CGI isn’t the only product line we handle as your General Contractor. Houston homeowners call us for KraftMaid cabinets, Cambria and Silestone countertops, and Kohler fixtures as well. That matters because a full remodel project – say, a kitchen that needs new windows along with cabinets and counters – shouldn’t require three separate contractors and three separate schedules. We can handle it under one written price.
FAQs – CGI Construction Service in Houston
A fogged CGI impact window can’t be repaired with a reseal – the moisture is trapped between the panes, and once the factory seal has failed, the insulated glass unit needs replacement. In most cases, we replace the glass and keep the existing frame when it’s still square and structurally sound, but on older Sentinel or Targa units where the frame has also shifted, a full sash replacement is the honest answer. Call (254) 272-5240 for an exact quote – estimates are free.
Yes, if your CGI window is still under factory warranty and you install glass or hardware that isn’t OEM, CGI can void the remaining coverage on that unit. That’s why we always recommend sourcing through CGI’s warranty channel while the coverage is active. If the warranty has expired, a Miami-Dade certified aftermarket laminated glass unit won’t affect any remaining coverage, because there isn’t any. We’ll walk you through the warranty status of your specific window before you commit to a part, and we’ll document it in writing.
We do. CGI Commercial/Architectural impact windows show up in a number of Houston mid-rise and high-rise buildings, particularly along the 610 Loop and in the Energy Corridor. Commercial work involves different logistics – freight elevator access, building permits, sometimes after-hours scheduling – but the service approach is the same: diagnose the frame square, source correct impact-rated parts, and finish with photo documentation of the clean-up. Call (254) 272-5240 with the building address and we’ll let you know the timeline.
No, that’s a symptom, not a seasonal personality. Houston’s heat makes frames expand, but a CGI slider that’s hard to open in August usually has a worn roller, a corroded track, or debris in the channel. If the track is clogged with dirt and the weep holes are blocked, water sits and accelerates corrosion. If the rollers are shot, the sash drags. Both are fixable without replacing the whole window in most cases. But don’t force a sticking slider – that turns a $200 roller replacement into a cracked frame. Call (254) 272-5240 and we’ll diagnose it.
You can replace one window, and we do it regularly. The challenge is matching the frame finish, glass tint, and grid pattern, which shifts between production runs. CGI’s Sentinel and Estate lines have changed slightly over the years, so an exact cosmetic match isn’t always possible on older windows. We’ll pull a sample before ordering and tell you honestly if it’ll be a close match or a noticeable one. If a full-house replacement is on your mind for other reasons – failing seals on multiple units, rising energy bills, or pre-hurricane-season hardening – we’ll give you a clear price per opening so you can phase the work. Call (254) 272-5240 to talk it through.
Impact window installation in Houston typically runs $8,000 to $25,000 for a full home, depending on window count, size, and whether the units are CGI specifically; a smaller window replacement project runs $4,500 to $15,000. Here’s the breakdown:
| Service | Price Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
Prices vary by the number of openings, frame material, and whether we’re dealing with load-bearing mullion assemblies or simple single-hungs. We write the exact price before work starts, and it doesn’t change unless you approve a change order. Call (254) 272-5240 for an exact quote – estimates are free.
