Why Austin Homeowners Choose CGI Construction

Penhallow Remodeling Austin provides independent CGI construction service across Austin, including CGI repair in Austin,, from impact window replacement to full kitchen remodels where CGI windows anchor the design. We’re not a factory-authorized dealer, and we won’t pretend to be. What we are is a local crew that has worked on hundreds of CGI-branded projects in Central Texas homes, which means we know how these products fail in Austin’s specific climate and how to fix them correctly. Call (325) 225-5429 for a written estimate on your CGI window or construction project.

CGI impact windows are a serious investment, and Austin homeowners choose them because they hold up against hail, wind, and the Texas sun better than most builder-grade glass. But any product has weak points, and in this city the weak points show up faster than the manufacturer’s brochure would suggest. We see the real-world behavior of CGI Sentry and Estate Collection windows on houses from Round Rock to South Congress, as well as CGI repair in Cedar Park,, and we know exactly what to look for when a seal fails or an install was done wrong by the original builder.

As an independent CGI service provider, we’re free to tell you the truth about what’s worth repairing and what’s worth replacing. We don’t get paid to defend a product line, and we don’t get kickbacks for selling more windows. We get paid to do the job right, write the guarantee down, and stand behind it for a year.

Why Trust Penhallow Remodeling Austin for Your CGI Construction?

A whole-home remodel with the living, dining and kitchen areas opened up

We’ve pulled apart enough CGI window frames in Austin to know the difference between a factory defect and a heat-stress failure. That matters because the fix is different for each. Trevor Nash, our owner, learned construction fundamentals at Los Angeles Trade-Technical College and has spent years on jobsites doing everything from foundation repairs to full kitchen rebuilds. He’s been serving Austin homeowners, including CGI in Georgetown, for well over a decade, and his approach to CGI work is the same as his approach to everything else: give the customer a real number on day one, then do exactly what you said you’d do.

Our technicians know the CGI Sentry Series impact window line inside and out. We understand how the laminated glass behaves during a hailstorm, what happens to the corner seals after five summers of 100-degree heat, and which weatherstripping compounds degrade fastest under Austin’s UV load. We use genuine CGI replacement parts when they’re available because impact-rated glazing and frame components demand exact fit and rating compliance. When a model is out of production, we source certified impact-rated equivalents and we’ll tell you plainly if a full replacement is safer than a structural repair.

Every CGI job we do carries the same written guarantee as every other Penhallow Remodeling Austin project. The 365-Day Done Right Promise is not a verbal pat on the back. It’s written into every contract: if the work fails inside the guarantee period, we come back and fix it at no charge. Free second visit. No service call fee, no re-inspection fee. That’s the deal, in writing, before we pick up a single tool.

Common CGI Construction Problems We Fix in Austin

These are the issues we run into most often on CGI products in Austin homes. Some are climate-driven, some are installation errors from the original build, and all of them have specific fixes that last when they’re done right.

  • Fogging between panes on CGI Sentry Series windows. This is a failed corner seal, and in Austin it happens most often on south-facing elevations where the midday sun bakes the frame. The seal breaks down, moisture gets pulled in during our humid summers, and you get that hazy film between the glass that won’t wipe off. The fix is a full glazing replacement, not a caulk job.
  • Deteriorated weatherstripping on CGI Sentry and Classic Collection windows. Austin’s intense UV exposure breaks down the original weatherstripping faster than the manufacturer’s lifespan estimates. You’ll feel the draft first, then see water staining around the sill. We replace the weatherstripping with compounds rated for high-UV environments and verify the air seal with a smoke test before we call it done.
  • Electrolysis pitting on older CGI Estate Collection aluminum frames. This one is distinctly Austin. Our water has high mineral content, and when sprinkler heads sit too close to a window, the repeated wet-dry cycles cause electrolysis that pits the aluminum frame. It’s cosmetic at first, but left alone it can compromise the frame’s structural integrity. We catch it early and resurface before it becomes a replacement job.
  • Water intrusion at the header from improperly flashed original installations. This is the most common failure we correct on CGI windows across Austin. Original builders skimped on the flashing, and the first heavy rain after a dry spell sends water down the inside of the wall. The window itself is fine; the install was the problem. We pull the trim, re-flash with full peel-and-stick membrane, and reinstall to code.
  • Cracked inner panes on CGI Targa Series windows after hailstorms. The outer impact layer does its job, but the inner pane cracks from the concussive force. On a Tarrytown remodel, our crew pulled three CGI Targa Series windows after a hailstorm revealed cracked inner panes. The original builders had shimmed the frames without full flange coverage, so we replaced the glazing, re-flashed with a full peel-and-stick membrane, and verified the impact rating was preserved after the repair.

CGI Parts & Our Repair-vs-Replace Approach

We use genuine CGI replacement parts whenever the model is still in production. Impact-rated glazing has to match the original specifications exactly if the window is going to keep its wind and debris rating, and aftermarket glass that’s “close enough” isn’t acceptable on a product protecting your home from Austin hailstorms. For older or discontinued CGI models, we source certified impact-rated equivalents that meet or exceed the original spec, and we document the rating on your invoice so there’s no question about what’s in the frame.

We keep a local stock of common CGI replacement components: weatherstripping, balances, rollers, and locking hardware for the Sentry, Estate, and Classic lines. That means we can usually diagnose and fix minor service issues in one visit without waiting on a parts shipment.

The repair-vs-replace decision comes down to structural integrity and cost. If a frame is sound and only the glazing or weatherstripping failed, repair is the honest call. If the frame is pitted, warped, or compromised at the corners, replacement is safer, and we’ll show you why instead of just telling you. Call (325) 225-5429 and we’ll give you a written line-item quote either way.

Our CGI Service Process – Step by Step

We don’t do mystery processes. Here’s exactly how a CGI service call works with Penhallow Remodeling Austin.

  1. 1
    Diagnosis. We inspect the window or construction envelope in person. We check the seals, the flashing, the frame condition, and the impact rating documentation. We tell you what’s wrong in plain English, not contractor shorthand.
  2. 2
    Written quote. You get a number before any work starts. It covers parts, labor, and disposal. That number on day one is the number on the invoice. No change orders, no “we didn’t see that coming” upcharge.
  3. 3
    Repair or install. Our background-checked, uniformed technicians do the work. For window replacements, we pull the old unit, inspect the rough opening, correct any flashing or water-management issues from the original build, and install the new CGI product to current code.
  4. 4
    Testing. We verify the impact rating is preserved, run water and air infiltration checks, and make sure the window operates smoothly. If it’s a kitchen remodel with CGI windows, we confirm the envelope is sealed before any finish work goes in.
  5. 5
    Warranty. Every job gets the 365-Day Done Right Promise in writing. If something fails inside that year, we come back and fix it at no charge. Freely.

CGI Products We Service & Install in Austin

A remodeled primary suite with built-in wardrobes and a window seat

We service and install the full CGI residential window line, including the CGI Sentry Impact-Resistant Windows, CGI Estate Collection Windows, CGI Targa Series Impact Windows, and CGI Classic Collection Windows. Our local stock covers common parts for these lines, which means faster turnaround on repair calls. We also handle the construction side of CGI work: full kitchen remodels where CGI windows are part of the design, roof replacement and installation that ties into the window envelope, and structural corrections when the original install wasn’t done properly.

If you have a CGI product that isn’t a window, ask us. We’ll tell you straight whether it’s in our scope or whether you need a different specialist.

We Also Service These Brands

CGI is one brand we know deeply, but it’s not the only one. Penhallow Remodeling Austin, a licensed General Contractor, works with KraftMaid cabinetry, Cambria and Silestone countertops, and Kohler fixtures on kitchen and bath remodels across Austin. That multi-brand experience means we can handle a full project without farming pieces out to subs who don’t know your CGI windows are part of the envelope.

FAQs – CGI Construction Service in Austin

Is Penhallow Remodeling Austin authorized by CGI?

No. We are an independent CGI service provider with extensive hands-on experience servicing and installing CGI products across Austin, but we’re not a factory-authorized dealer. That independence lets us be honest with you about repair-versus-replace decisions without any pressure to sell new product.

Do you use genuine CGI/OEM parts?

Yes, whenever the model is still in production. Impact-rated glazing and frame components require exact fit and rating compliance, so we don’t gamble with mismatched aftermarket glass. For discontinued models, we source certified impact-rated equivalents and document the rating on your invoice.

How long does CGI service take?

Most individual window repairs in Austin take one half-day visit when parts are in our local stock. Full window replacements run one to two days depending on the number of units. Kitchen remodels involving CGI windows follow the project schedule we outline in your written quote before work begins. Call (325) 225-5429 for a specific timeline on your job.

What CGI models/series do you cover?

We service the Sentry Impact-Resistant Windows, Estate Collection Windows, Targa Series Impact Windows, and Classic Collection Windows. Our local parts stock covers common components for all four lines.

Will service void my CGI warranty?

Using an independent contractor does not void a CGI manufacturer’s warranty on its own, but installing non-compliant parts or executing a repair that compromises the impact rating can. We use genuine CGI parts when available and we document every repair to preserve your warranty standing. We’ll walk you through what your specific warranty covers before we start.

How much does CGI construction cost in Austin?

Here are the ranges we quote most often for CGI-related work in Austin:

Service Typical Austin Price Range
Impact Window Installation $8,000 – $25,000
Window Replacement $4,500 – $15,000
Roof Replacement $8,000 – $20,000
Full Kitchen Remodeling $14,000 – $45,000

These are written, line-item ranges, not verbal ballparks. The final number depends on square footage, cabinet line, countertop material, and how many windows are involved. Call (325) 225-5429 for an exact quote. Estimates are free.

Can you match the existing CGI window finish if we replace only a few panes after storm damage?

Yes, finish matching is a standard part of our storm-damage repair scope. We’ll match the frame color and glass tint as closely as the current CGI product line allows, and we’ll tell you upfront if an exact match isn’t possible before you commit to the work.

Do CGI impact windows insulate as well as regular insulated glass in Austin’s heat?

Yes, and in most cases better. Modern CGI impact windows use laminated glass with a low-E coating and an insulating airspace that performs comparably to standard dual-pane insulated glass. The difference in Austin comes from the durability under hail and wind load, not a thermal penalty. We’ve measured surface temperatures on both, and the real-world delta is small.

My CGI window is fogging between the panes. Is it a seal failure or something else?

If the fog is between the two panes of glass, it’s a seal failure. The corner seal has broken down, moisture has entered the airspace, and no amount of cleaning will fix it. In Austin, this is most common on south-facing elevations where years of 100-degree heat stress the seal. The fix is a full glazing replacement, not a seal patch. Call (325) 225-5429 and we’ll confirm the diagnosis in person.

Can you expand an existing CGI window opening to a larger size without compromising impact rating?

Yes, but it’s structural work, not just a window swap. We bring in an engineer when the opening change affects load-bearing walls, which it usually does. The expanded CGI window must meet the same wind and debris rating as the original, and we verify that before we close the wall. This is a job we do as part of a larger remodel, and your written quote will reflect the framing, header, and engineering costs.

Are CGI replacement parts like weatherstripping and balances readily available in Austin?

Yes. We keep a local stock of common CGI replacement parts in Austin, including weatherstripping, balances, rollers, and locking hardware for the Sentry, Estate, and Classic lines. For less common parts, we order from CGI distribution and typically have them in hand within a few days.
