AfterCGI Construction in Houston, CA | Rowan Construction Group
Rowan Construction Group provides independent CGI window and door service across Houston, from Heights bungalows to Sugar Land tract homes. The service call that separates us from every other contractor is simple: before we touch a CGI unit, we check whether the home sits on expansive clay, inside a revised FEMA floodplain, or both, because those two Houston realities dictate what a correct repair actually looks like. We’re a local contractor with a documented price in writing before any work starts. Call (470) 298-9650 to schedule a free estimate.
Why Houston Residents Choose Us for CGI Service
We’ve installed and repaired CGI windows and doors across hundreds of Houston homes without ever being beholden to a manufacturer’s playbook. That independence matters. When a CGI unit fails, you need someone who will tell you what’s worth fixing and what’s worth replacing, not someone who has to protect a dealership territory or move a stockroom of product. Our CGI sales & service experience covers the Sentinel Series, Estate Collection, Clasic Series, and 900 Series sliding doors, and we keep the full parts conversation in plain language.
Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College, where the coursework covered framing, concrete, and project estimating before he ever picked up a hammer for a paying client. That estimating discipline is the through-line: every CGI job we quote in Houston gets a flat written price, a written scope, and a written warranty before a single screw is removed. We’re not authorized by CGI, and we’ll never claim to be. We’re an independent Houston contractor who happens to know these products cold, and we also offer Fence Installation - Houston.
Common CGI Construction Problems We Solve in Houston
- Fogging between panes on early-2000s CGI insulated units. Houston’s humid summers and rapid overnight temperature drops push thermal cycling hard. The seal fails, moisture gets pulled into the air space, and the glass fogs permanently. This shows up most often on west-facing elevations in Katy and Clear Lake homes built between 1998 and 2006.
- Sagging or binding CGI 900 Series sliding doors on pier-and-beam homes. The Heights, Montrose, and Eastwood are full of early-20th-century bungalows that sit above the slab. Clay soil movement heaves the underlying framing, the rough opening drifts out of square, and a 300-pound impact-rated door starts dragging. You can shim it for a while, but the real fix usually means re-leveling the opening first.
- Corroded bottom-track weep holes on CGI doors in Clear Lake and Friendswood. Pooling rainwater mixed with coastal air salts eats through the aluminum track at the drain points. The track stops draining, water backs up, and interior trim starts swelling. We replace tracks and hardware with marine-grade stainless where CGI’s original spec allows.
- Warped wood interior trim around CGI frames in unconditioned sunrooms. Houston’s humidity swings, sometimes 40% to 95% within a single week, are hard on untreated or lightly sealed wood. The glass is fine. The trim pulls away at the corners. We replace it with properly primed and sealed material built for Gulf Coast moisture cycling.
- Bent or binding casement hardware on CGI Estate Collection windows after impact debris hits. Even when the laminated glass survives a storm, the hardware is often what takes the hit. A wind-thrown branch catches the exposed hinge, the sash misaligns, and the crank fights you every time. We carry OEM CGI hardware replacements for the most common Estate and Sentinel models.
BeforeAfterCGI Service in Houston: What Local Conditions Mean for Your Equipment
Houston’s post-Harvey FEMA map revisions and Harris County’s “substantial improvement” rule have rewritten what a window replacement means in neighborhoods like Meyerland, Friendswood, and Kashmere Gardens. Here’s the checkable fact: if a flood-damaged home’s repair or remodel cost exceeds 50% of the structure’s assessed value, the entire building must be brought into current floodplain compliance, and that often includes elevating the structure to the new Base Flood Elevation plus freeboard. So a homeowner in Meyerland who just wants to replace three broken CGI windows can walk into a five-figure whole-house lift requirement if the scope triggers the threshold. We don’t let that be a surprise. Before we quote any CGI work in a flood-prone Houston neighborhood, we check the FEMA panel, the county’s substantial improvement triggers, and the existing permit history. Then we tell you the truth, even when the truth is that a simple window swap should be folded into a larger structural elevation plan to avoid double work.
That’s the local knowledge a generic CGI page can’t give you. It’s also why we coordinate with permit-ready structural elevation plans before any window or door gets swapped on a repeatedly flooded property in Houston.
CGI Models & Products We Service in Houston
We service the full CGI residential lineup: Sentinel Series impact windows, Estate Collection impact windows, Clasic Series impact windows, and 900 Series sliding glass doors. For structural impact-rated components, we always try OEM CGI glass packs and hardware first, because those are the parts that carry the Miami-Dade testing certification. When CGI parts are backordered or cost-prohibitive, we use high-quality aftermarket weatherstripping, rollers, and balance springs, and we tell you exactly what’s OEM and what’s not on the written quote. For older CGI units with failed seals or bent frames, we’re honest that a full sash or door replacement usually costs less long-term than repeated glass-only fixes. We stock common CGI hardware locally in Houston for faster turnaround, and we can have glass packs cut and laminated to spec within a week for most Eagle and Sentry line units.
CGI Service Pricing in Houston

Three things drive your price in Houston: the condition of the rough opening (clay heave adds time and shim work on pier-and-beam homes), whether floodplain compliance rules apply to your property, and whether we’re replacing one sash or a full elevation of impact-rated glass. A free estimate includes a written line-item breakdown, a photo record of what we find, and a flat price that doesn’t change without a signed change order. That’s Clause 1 of the Haven Standard, the way we’ve quoted every job since 2007. Call (470) 298-9650 to get your written number.

FAQs - CGI Construction in Houston
Yes, and it’s the first thing we check. Clay soil movement pulls pier-and-beam framing away from square over the course of decades, so a CGI window installed into a drifted rough opening will bind, leak, or shatter a pane within a few seasons. The correct fix is to measure the opening’s true dimensions and square it before the new window goes in, not to force the window into a bad opening and then wonder why the sash sticks. In the Heights and Montrose, we almost always shim packs and re-flash the opening to account for accumulated movement. Call (470) 298-9650 and we’ll inspect your framing first.
Sometimes, but rarely. If the frame is straight and the fogging is from a seal failure, a glass-pack replacement can work. But on early-2000s Estate Collection units, the frame is often starting to fatigue where the mullion meets the sill, and you’ll likely pay nearly as much for a glass pack as you would for a full replacement sash. We always show you both numbers and let you choose. For a free line-item comparison, call (470) 298-9650.
It can. The rule counts the total repair and improvement cost against 50% of the structure’s assessed value. A like-for-like window replacement on its own usually stays under the threshold, but if your Meyerland home also needs drywall, electrical, and flooring work after a flood, the window replacement gets added to the total. The county’s trigger applies to the cumulative cost. We check FEMA panels and the county’s substantial improvement thresholds before we quote any CGI work in a flood-prone Houston neighborhood so you’re not surprised mid-project. Call (470) 298-9650 for a no-cost review of your property’s floodplain status.
Your slab has moved. Sugar Land sits on some of the most expansive clay in the Houston area, and repeated shrinking and heaving cycles slowly pull the door track out of level. Once the track drops even 1/8 inch, the full weight of an impact-rated 900 Series door lands on the lowest roller, which eventually grinds flat. The long-term fix is to grade-beam the slab or re-level the track, not just swap rollers every two years. We’ll diagnose the track condition and give you the straight answer. Call (470) 298-9650.
In most cases, yes. A straight swap where the rough opening doesn’t change often falls under a simple residential window replacement permit, but Houston’s lack of traditional zoning means deed restrictions and Chapter 42 lot-platting rules can add a second layer of approval in some neighborhoods. We pull the permits for you, schedule the inspections, and hand you the signed documentation when the job closes. Call (470) 298-9650 for a scope-specific answer on your property.
