Why Sarasota Homeowners Choose CGI Windows & Doors
We provide independent CGI service in Sarasota, from full impact-rated replacements to surgical repairs on Sentry Series sliders and Estate Collection casements. Our crews work on CGI products weekly, which means we know how these windows and doors fail in this specific coastal environment before we ever pull a sash. We are not a CGI dealer and we are not authorized by the manufacturer. We are an independent service provider, and that independence lets us tell you straight when a roller swap fixes the problem and when a full sash replacement is the only honest answer. If you have a CGI window or door that is sticking, fogging, sagging, or leaking, call (941) 214-2069 for a free estimate.

Why Trust TruePane Windows & Doors for Your CGI Windows & Doors?
CGI builds a serious impact product. Sentry Series, Tribute Series, the Estate Collection, and the Custom Impact Line are all engineered for Florida wind loads and missile impact ratings. But even the best window is only as good as the hands that set it, and hands that understand CGI specifically are harder to find than most people realize. Our technicians have been working on CGI hardware for years. We know which Sentry Series sash balances wear out first, which Tribute roller assemblies bind under salt exposure, and which Estate casement hinges sag when the coastal air gets to them. That familiarity means faster diagnosis and fewer wrong parts. Dale Kessler founded TruePane Windows & Doors in 2008 after growing up in his father’s glass shop in Columbus, Ohio, cutting lites and setting frames before he was old enough to drive. He sharpened that hands-on training with building systems coursework at Columbus State Community College, and for the better part of two decades he and our crew have worked the Gulf Coast, including full window and door replacements on Siesta Key homes where salt air and storm exposure make a sloppy install a real liability. Dale reads a rough opening the way other people read a room. He catches what is off before the first piece of glass is unloaded.
Every CGI job we touch is covered by our 90-Day Done Right Promise and The Keystone Standard. Both manufacturer warranty layers get registered in writing, durations stated, before our truck leaves your driveway. If something is not right, we make it right. No paperwork fights. No arguing. That is the standard on the first visit and the baseline for every callback.
Common CGI Windows & Doors Problems We Fix in Sarasota
CGI products are built tough, but Sarasota is tougher on them than most markets. Salt air off the Gulf, high humidity, storm-driven debris, and decades of direct sun all take their toll. These are the issues we see most often on CGI windows and doors in Sarasota:
- Fogging between panes in Sentry Series insulated glass units. The butyl seal that keeps the argon or krypton fill inside an IGU eventually breaks down, especially when coastal moisture accelerates the failure. You will see condensation inside the glass that you cannot wipe away. The fix is a new OEM sash or IGU, re-bedded properly so the frame stays untouched. We did exactly this on a 2015 Sentry Series double hung in Palmer Ranch, replacing a failed butyl seal and setting the new OEM sash without disturbing the frame.
- Sticking or derailing 3-lite sliders from worn roller tracks. The steel rollers inside CGI sliding assemblies corrode in salt air faster than most manufacturers anticipate. When the roller surfaces pit, the door stops gliding and starts dragging, and eventually the panel can jump the track. On a Gulf Gate 3-lite roller, we resquared the track and swapped the worn steel rollers for stainless ones. The hard pull disappeared and the door moved like it should.
- Sagging casement sashes from hinge wear in coastal salt air. Casement hinges carry the full weight of the sash every time it opens. When standard hinges corrode, the sash drops a few millimeters, the latch no longer aligns, and you feel the drag every time you crank it. We replace the hinges and realign the sash before the frame gets scarred from metal-on-metal contact.
- Failed impact glass seals from storm debris micro-fractures. Impact-rated glass is designed to take a hit without shattering, but a piece of storm debris can leave hairline fractures in the outer lite that compromise the seal. Water intrusion and interior fogging follow. If the structural integrity of the impact laminate is compromised, we tell you honestly and recommend replacement rather than a seal patch that will fail again.
- Warped or binding frames on older Tribute and Estate Collection units. Temperature cycling and salt exposure can warp aluminum frames over time, especially on large fixed panels and tall sliders. A warped frame cannot be repaired with new hardware alone. We measure the frame deflection, confirm the impact rating is still intact, and recommend full frame replacement only when it is genuinely necessary.
CGI Parts & Our Repair-vs-Replace Approach
We use CGI OEM parts when they are available and when the component is structural or impact-critical. Sash balances, roller assemblies, hinge hardware, and insulated glass units for Sentry Series and Tribute Series should come from the manufacturer or a source with equal or better coastal ratings. For obsolete hardware that CGI no longer produces, we source matching aftermarket parts with verified corrosion resistance rather than whatever generic part is closest on the shelf. A cheap steel roller in a Gulf-front slider is a callback waiting to happen. We do not do that to our customers.
Our repair-versus-replace decision is straightforward. We repair rollers, hinges, balances, and weatherstripping when the frame is sound and the impact rating is intact. We recommend full sash or frame replacement when the frame is warped, the glass laminate is compromised, or the unit no longer meets current Florida Building Code wind-load requirements for Sarasota County. We put the trade-off in writing so you can see exactly what each option costs and why. Call (941) 214-2069 for an honest assessment. Estimates are free.
Our CGI Service Process - Step by Step
- 1
Diagnosis. We inspect the unit, measure the frame and sash, check the rollers, hinges, balances, and seals, and identify the root cause. For CGI impact products, we also confirm the laminate and frame are still structurally sound enough to meet Sarasota County wind-load requirements.
- 2
Options on paper. We quote repair and replacement side by side, with OEM parts specified and warranty durations stated. You see exactly what you are buying before we order anything.
- 3
Repair or install. Our background-checked, uniformed technicians do the work. For structural and impact-critical components, we use OEM parts. For obsolete hardware, we source aftermarket with equal or better coastal ratings.
- 4
Testing. Every sash is cycled, every seal is checked, every lock is exercised. If it is not square and it is not sealed, we are not done.
- 5
Warranty registration. We register both manufacturer warranty layers in writing before the truck leaves the driveway. That is The Keystone Standard, and it applies to every CGI job we complete.

FAQs - CGI Windows & Doors Service in Sarasota
Can you still service my CGI Sentry Series windows if CGI no longer makes that exact sash?
Yes. We source OEM stock when available, and for discontinued Sentry Series sash sizes we work with fabricators who can match the glass package and hardware specifications to the original unit. We also keep a local inventory of common Sentry Series balances and hardware to speed up repairs. Call (941) 214-2069 and we will tell you exactly what is available for your window.
What causes fogging in CGI impact windows and is it repairable?
Fogging happens when the butyl seal around the insulated glass unit fails and moisture gets between the panes. In Sarasota’s humidity, that happens faster than in drier climates. The repair involves replacing the IGU or the entire sash with a properly sealed OEM unit. It is repairable without replacing the frame. If you are seeing fog, the sooner you address it the less chance there is of frame damage from trapped moisture. Call (941) 214-2069 for a free estimate.
Do I need to replace the whole frame if my CGI casement sash is sagging?
Usually not. Sagging casements are most often caused by worn or corroded hinges, not frame damage. We replace the hinge set, realign the sash, and test the latch. The frame only needs replacement if it has warped beyond adjustment or if the impact rating has been compromised. We will show you the measurements and let you decide with real numbers in front of you.
How do I know if my CGI windows still meet Sarasota hurricane code after a repair?
The Florida Building Code sets wind-speed design requirements for Sarasota County, and a repair that leaves the frame or laminate compromised may no longer meet those requirements. We inspect the structural condition of the frame, the glass laminate, and the anchoring system after every repair. If the unit no longer meets code, we tell you in writing and recommend replacement. We do not patch over a code compliance problem.
Can you convert my existing CGI 3-lite sliding door to a smoother, more secure roller system?
Yes, and this is one of the most common upgrades we perform on CGI 3-lite sliders in Sarasota. We resquare the track, replace worn steel rollers with stainless hardware rated for coastal exposure, and adjust the panel alignment. The result is a door that moves easily and locks securely. Call (941) 214-2069 for an exact quote. Estimates are free.
How much does CGI windows and doors service cost in Sarasota?
Repair costs vary by the component and the model. Roller replacements on a 3-lite slider typically run lower than full sash replacements, while a fogged Sentry Series IGU replacement falls in the middle range, and full frame replacements on warped Tribute or Estate units are the high end. We quote line-item pricing in writing before any work starts, with no surprise line items on the bill. Call (941) 214-2069 for an exact quote on your specific CGI window or door.
