Why Austin Homeowners Choose CGI Construction
We provide CGI repair in Austin, from impact window replacement on Mueller bungalows to metal roof systems on Westlake hillsides. We repair and install CGI Sentinel Series, Estate Collection, Commercial Series, and 950 Series products, and we’re the crew Austin homeowners call when a failed seal or hail-cracked impact glass needs a straight answer, not a sales pitch. As an independent CGI service provider, Mason Remodeling Co Austin is not affiliated with or authorized by CGI. We simply work on their products every week and know them inside and out.
If you own CGI windows, doors, or roofing trim in Austin, call (903) 623-1966 and we’ll give you a written price before any work begins.
Why Trust Mason Remodeling Co Austin for Your CGI Construction?

CGI builds impact-rated products for hurricane zones, but Austin throws its own set of problems at them: hail the size of golf balls, humidity that never quits in August, and west-facing elevations that bake in 100-degree heat. Our crews see how those conditions age CGI components. We know which Sentinel Series units tend to lose their argon fill first, why Estate Collection weep holes clog with limestone dust and pollen, and what happens when a 950 Series door gets slammed by storm pressure one too many times.
Isaac Pruett, our owner, learned construction at Los Angeles Trade-Technical College and spent years on residential and commercial jobs up and down the West Coast before bringing his crew to Austin. He’s the one who walks each CGI job before we quote it. His rule is simple: “Tell me what’s wrong with it. We’ll figure out what it actually needs.” That’s how we avoid replacing a whole window when a sash swap and new glazing bead would do the job right.
We carry OEM-compatible parts for current CGI lines and work with AAMA-rated aftermarket impact glass for discontinued series. Every quote comes in writing before we start. Every job ends with a written guarantee, clear on what’s covered and for how long.

Common CGI Construction Problems We Fix in Austin
These are the issues we see most often on CGI products in Austin homes, from 1950s bungalows in Crestview to 2010s builds in Steiner Ranch and Pflugerville:
- Fogging or condensation between panes on Sentinel Series units. Once a dual-pane seal fails, moisture gets trapped between the glass. On 15-plus-year-old Sentinel windows, the argon fill leaks out and the unit loses its thermal performance. We often see this on west-facing bedrooms that get full afternoon sun. The fix is usually a new sealed insulated glass unit or an OEM sash replacement, not a whole window.
- Impact glass stress cracks from hail or flying debris. Austin’s spring hailstorms crack impact-rated glass more often than people expect. A stress crack from impact doesn’t always shatter the pane, but it compromises the impact rating and can spread. West-facing elevations take the hardest hits. We assess whether the sash can be reglazed or the entire unit needs replacing.
- Frame corrosion at weep holes on Estate Collection windows. Humidity and hard water in Austin accelerate corrosion around the small drainage openings at the bottom of the frame. When those weep holes clog or corrode, water backs up and leaks inside the wall. We clean, treat, and reseal, and replace frame sections when the extrusion is too far gone.
- Misaligned sash operation on 950 Series doors. Repeated forced closures and storm pressure can throw a 950 Series door out of square. The sash drags, the lock doesn’t engage cleanly, and the weatherstripping tears. We realign, replace worn rollers and hinges, and adjust the strike plate so the door operates like it did when it left the factory.
- Improper flashing from the original installation. Even a great CGI window leaks if the flashing wasn’t done right in the first place. We find this on homes built during the 1990s and early 2000s boom, when crews moved fast and skipped details. We pull the trim, reflash the opening with modern materials, and reseal so water stops finding its way in.
CGI Parts & Our Repair-vs-Replace Approach

We always start with the question: what does this product actually need, and what’s the honest cost either way? For current CGI lines like the Sentinel Series and Estate Collection, we order OEM sashes, frames, and hardware when lead time allows. The fit is exact, and the warranty path stays clean. For discontinued older series, we specify AAMA-rated aftermarket impact glass and gaskets that match the original energy performance and impact rating. We tell you which direction we’re recommending and why.
The decision to repair or replace usually comes down to two things: whether the frame extrusion shows delamination or corrosion, and whether the insulated glass unit has breached. If either is true, replacement is usually the better long-term play because it keeps the whole impact rating intact. If the frame is sound and the failure is a worn roller, a bad seal on a serviceable sash, or a clogged weep, we repair. We don’t oversell replacements in Austin; we’d rather give you an honest number and earn the next job.

Our CGI Service Process – Step by Step
- 1
Diagnosis. We inspect the window, door, or roof trim in person. We check seal integrity, frame condition, sash alignment, drainage, and flashing. We look at the brand and series markings to confirm the exact CGI model and vintage.
- 2
Written estimate. You get a line-item price in writing before any work starts. That includes parts, labor, and any flashing or trim work the job needs. No verbal ballparks, no surprise invoices.
- 3
Repair or install. Our crew arrives in clean marked uniforms with photo ID badges. You know who’s coming before they knock. We use OEM parts when available, AAMA-rated aftermarket when the series is discontinued, and we protect your floors and walls while we work.
- 4
Test and verify. We operate every sash, check the locks, run water on freshly flashed openings, and make sure the impact rating hasn’t been compromised. On roof trim and metal work, we inspect the details before we call it done.
- 5
Written guarantee. Every completed project gets a written warranty with clear terms: what’s covered, what’s excluded, and for how long. If something fails, we come back. No charge for the return visit.

FAQs – CGI Construction Service in Austin
No, we are an independent CGI service provider, not an authorized CGI dealer or warranty station. What that means for you: we work on your CGI products with the same care a manufacturer-trained installer would, but we don’t route through CGI’s corporate service process. We make decisions based on what’s best for your home and budget, and we stand behind our work with our own written guarantee.
Yes, whenever lead time allows on current CGI lines like Sentinel Series and Estate Collection. For discontinued series where OEM is no longer available, we source AAMA-rated aftermarket impact glass and gaskets that match the original energy and impact performance. We’ll always tell you which parts we’re using and why. Call (903) 623-1966 and we’ll quote your exact situation.
Most single-sash replacements and hardware repairs finish in one visit, usually two to four hours depending on the opening. Full window replacements and impact door installs typically run one to three days. Larger projects like whole-home impact window retrofits or metal roof installations with CGI trim run one to three weeks, and we put the timeline in writing with your estimate.
We service Sentinel Series, Estate Collection, Commercial Series, and 950 Series products, which covers the vast majority of CGI windows and doors installed in Austin. If you have an older or uncommon unit, we can identify it from the marking and tell you honestly what’s serviceable and what should be replaced.
Here’s the reality: if your CGI product is still under the original manufacturer’s warranty, using a non-authorized contractor for major component replacement could affect that coverage. We tell you this before we touch anything. Many Austin homes with 15-plus-year-old CGI units are well past the original warranty window, which is where our work comes in. For current products under warranty, we can advise you on whether a manufacturer service path makes more sense. Call (903) 623-1966 and we’ll walk you through it.
CGI impact window replacement in Austin typically runs $1,200 to $3,400 per unit installed, depending on size and series. Impact door replacement on a 950 Series unit ranges from $4,500 to $11,000. Full window replacement projects using CGI impact-rated units run $12,000 to $25,000. For a written estimate on your specific scope, call (903) 623-1966. Estimates are free, and the price we give you is the price you’ll pay.
If your frame is sound and the only failure is a breached seal or cracked glass, we can often replace just the insulated glass unit rather than the entire sash. The decision depends on the vintage of your Sentinel Series unit and how the glazing bead is secured. Older Sentinels sometimes use a glazing method that makes a sash replacement cleaner and more cost-effective long-term. We’ll show you the numbers for both options before you commit.
Most of the sill leaks we see on Estate Collection windows in Austin trace back to installation: improper flashing, missing backer rod, or sealant failure at the head and sides. It’s usually not a manufacturing defect, and it’s typically repairable without replacing the window. We pull the trim, inspect the rough opening, reflash, and reseal. If we find factory frame corrosion at the weep holes, we’ll show you the damage and give you a written quote for a frame section or full unit replacement.
Yes. We keep common roller assemblies, adjustable hinges, closers, and strike plates for 950 Series doors in stock or available within a few days. If your door is dragging, the lock won’t catch, or the closer lets it slam, we can usually fix it in one visit without replacing the door.
Most insurers in Texas accept wind mitigation documentation from properly permitted impact window installations, regardless of whether the contractor is manufacturer-authorized. What matters to the insurance company is that the windows meet the impact rating standard and the installation was done to code. We pull permits when required, provide the documentation you need, and make sure the installation matches the rating on the product. If your carrier has specific form requirements, bring them up and we’ll make sure you get what’s needed.
We can’t always match a 1998 tint exactly, because glass coatings and tints have changed in the past two decades. What we can do is spec the closest current CGI glass package to your original and, when the difference is noticeable, recommend replacing units by elevation so the variation doesn’t stand out. We’ve done this on homes across Austin, and the result rarely draws the eye once the full elevation is uniform.
CGI Construction Pricing in Austin

| Service | Price Range (Austin, TX) |

A recent job in Lake Travis illustrates how we work. Our crew pulled a failed CGI Sentinel Series double-hung out of a 2004 home. The seal had let go and the argon was gone, so the west-side bedroom was sweating and heating up every afternoon. We ordered a direct-match OEM sash from CGI’s current Sentinel line, reinstalled with new stainless clips, reflashed the opening, and the customer’s power bill dropped within one billing cycle. That’s the kind of fix we’d rather sell than a full window replacement.
