CGI Windows & Doors Service Nationwide

Why Austin Homeowners Choose CGI Windows & Doors

We provide independent CGI windows and doors repair, service, and replacement across Austin, TX. Homeowners call us when a CGI Estate slider starts dragging through cedar pollen, when a Sentinel casement crank spins without moving the sash, or when a west-facing picture window warps from years of Texas sun. Juniper Windows Austin is not a CGI dealer or authorized service center. We’re an independent windows and doors specialist, and we work on CGI products weekly, which means we know their failure patterns better than most. Call (325) 420-1750 for a written estimate before any work begins.

CGI builds impact-rated aluminum windows and doors designed for coastal hurricane zones. That’s exactly why they show up in Austin. Our hailstorms, our 100°F summers, our occasional straight-line wind events. Austin homeowners who want a window that holds up to real weather often land on CGI. The tradeoff: aluminum frames expand and contract hard under Austin’s temperature swings, and the hardware and weatherseals take abuse from cedar pollen, limestone dust, and relentless UV. We service the full CGI Estate Collection, the Sentinel Series, Estate Fixed and Picture Windows, and Estate Sliding Glass Doors. If it carries the CGI name and it’s in a home anywhere from Hyde Park to Steiner Ranch to Cedar Park, we’ve likely worked on one this month.

Why Trust Juniper Windows Austin for Your CGI Windows & Doors?

Our techs service CGI repair in Austin weekly across the hill country and lakefront homes, where thermal expansion and storm exposure stress frames differently than flat city lots. That hands-on field data lets us repair and tune CGI products without relying on manufacturer authorization. We see patterns the factory manuals don’t cover. A CGI Estate slider on Lake Travis accumulates cedar pollen in the bottom track all spring. A Sentinel casement on a west-facing Mueller home bakes in the afternoon sun until the weatherstripping turns brittle years early. These are Austin problems, not generic CGI problems.

Sean Mackey, owner of Juniper Windows Austin, grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending decades focused on how windows actually perform, not just how they look in a showroom. He and his crew have been serving Austin homeowners for years, from tight bungalow retrofits in Hyde Park to full door and window packages on new builds closer to the Domain. Sean is known for being straight with clients about U-factors, lead times, and what a realistic installation day actually looks like. No surprises on either end. If the numbers don’t back it up, he’s not going to sell it to you.

Every CGI job we take gets a written price before a single screw turns. Background-checked, uniformed technicians show up with a live arrival time you can track, and you get before-and-after photos and a digital invoice you can pay from a link. If something isn’t right, the 365-Day Done Right Promise covers it: parts and labor, in writing, for a full year after installation.

Common CGI Windows & Doors Problems We Fix in Austin

Here’s what we actually see on CGI products in this market, and why each one happens:

• Warped sashes on wide CGI Estate picture windows. West-facing homes on Lake Travis and in the hill country catch brutal afternoon sun. The aluminum frame on a wide Estate fixed window absorbs that heat and expands unevenly against the glass. Over several summers, the sash can bow enough to compromise the seal and even stress the glass edge. Once a sash warps, straightening it is rarely worth the attempt. We tell homeowners honestly when a replacement sash or full window is the smarter spend.
• Roller track wear on CGI Estate sliding glass doors. Hill Country cedar pollen and limestone grit pack into the bottom track. Every cycle of the door grinds that debris into the rollers until they wear flat on one side. The door drags, the track gouges, and eventually the panel binds. We replace OEM rollers, clean and re-align the track, and add a brush seal kit. Then we show the homeowner how to flush the track seasonally.
• Failed weatherstripping on CGI Sentinel casement windows. Austin’s UV loads and dry heat break down rubber weatherseals faster than the manufacturer’s coastal assumptions. When the weatherstripping on a Sentinel casement goes, you feel air leaks and see dust intrusion at the sash perimeter. We replace with OEM weatherseals sized for the specific Sentinel unit, then test the closure pressure.
• Sticking balances on CGI Estate double hung windows. Limestone dust is so fine it works into the balance channels and gums up the spring mechanisms. A double hung that used to glide now sticks mid-travel or won’t stay up. Cleaning alone rarely fixes it. We pull the sash, flush the channel, and replace the balance with OEM CGI parts when the unit’s still under warranty.
• Lock gapping on Estate double hung windows. If a double hung shows a gap on one side when locked, the sash isn’t seating evenly in the frame. Often it’s a misaligned balance or a warped jamb liner, sometimes it’s installer error from a previous retrofit. The fix depends on the cause, and we diagnose it with the sash out, not with guesswork.

CGI Parts & Our Repair-vs-Replace Approach

We use OEM CGI parts where they matter for warranty and fit. Balances, rollers, and weatherseals are the three categories where aftermarket substitutions cause the most callbacks, so we stay with CGI components there. If a homeowner is past warranty and needs a faster or less expensive fix on a structural component, we’ll recommend a quality aftermarket part and say so plainly, with the tradeoff stated up front.

For sashes with warped frames or compromised glass, we give an honest replace-over-repair recommendation-sometimes that means our Window Replacement services-before spending money on parts that won’t hold up. That’s the conversation we have most often on wide Estate picture windows. The sash has already moved. New weatherstripping won’t un-bow it. We’d rather tell you that in the first visit than take your money for a fix that fails in six months. Call (325) 420-1750 and we’ll diagnose your CGI unit and give you a written price either way.

Our CGI Service Process – Step by Step

Every CGI job follows the same sequence, whether it’s a slider tune-up in Steiner Ranch or a full frame replacement near Mueller.

1. 1
   Diagnosis. The tech removes the sash or inspects the door panel on-site. We check the rollers, balances, weatherseals, and frame alignment, and we test the unit’s operation under its actual load. No guesswork and no pricing before we know what’s actually wrong.
2. 2
   Written price. You get a line-item quote before any work starts. Parts, labor, and timeframe in writing. The price does not change at the door.
3. 3
   Repair or replacement. We use OEM CGI parts for balances, rollers, and seals. For full frame replacements, we pull the old unit, prep the opening, and install the new CGI product to the manufacturer’s spec, with shim and seal details done right for Austin’s heat cycles.
4. 4
   Testing. Sliders get a full-extension glide test and track inspection. Double hungs get the balance tension checked through the full travel. Casements get a closure pressure test. Impact glass gets a visual inspection of the laminate edge.
5. 5
   Warranty and follow-up. The work is covered by our 365-Day Done Right Promise, parts and labor, in writing. If a repair fails within a year, the second visit is free. No charge, no argument.

CGI Products We Service & Install in Austin

We work on the CGI Estate Collection, including Estate Fixed and Picture Windows, Estate Sliding Glass Doors, and the Estate double hung line. We also service the CGI Sentinel Series casement and awning windows, which are common in Austin hill country homes where owners wanted impact-rated units without going full estate-package pricing. Our sub-service focus includes horizontal roller and sliding impact windows, hurricane-proof front and entry doors, and full frame replacement. We keep common OEM parts, rollers, balances, and weatherseals for these lines in local stock for faster turnaround on typical Austin failures.

One field note from the file: our crew pulled a bowed CGI Estate sliding door in a Lockhart area lake home. The bottom track was packed with cedar pollen and the rollers had worn flat on one side. We replaced the OEM rollers, re-aligned the door, and added a brush seal kit, then showed the homeowner how to flush the track seasonally. Door glides like new again. That’s the kind of fix a generic window repair page won’t tell you about, because they haven’t done it in Austin.

We Also Service These Brands

CGI is one line we know well, but Juniper Windows Austin carries and services eight product lines total, including PGT, CWS, ES Windows, and ECO Window Systems, along with Therma-Tru and ViewLux for door projects. If a CGI repair quote doesn’t make sense and a replacement from another line does, we’ll say so without hesitation.
