CGI Windows & Doors in Jacksonville, OH | TruePane Windows & Doors
We service CGI windows and doors across Jacksonville, and we do it as an independent company, not a factory arm. The thing that sets our CGI work here apart is that we know Jacksonville’s split wind zone code inside out, so you don’t pay for impact glass you don’t need and you don’t fail an inspection for glass you do. If you own CGI windows or doors in Jacksonville, call (888) 635-0804 and you’ll get a live person who can talk through your issue on the spot.
We’re factory-trained on CGI product lines and carry proprietary calibration data for their multi-point locking systems. But being independent means we quote the repair first when a repair makes sense. A corroded track or a seized locking gearbox doesn’t always mean a full replacement, and we won’t pretend otherwise. Our shop carries OEM CGI parts for Sentinel and Estate lines, plus American-made aftermarket hardware that matches the original spec for older Classic Series units. If you need our Window Installation in Jacksonville or door service, we’ll tell you straight what it needs and what it’ll cost.
Why Jacksonville Residents Choose Us for CGI Service
Dale Kessler grew up in Clintonville watching his father spend thirty years doing glass work on older homes with original wood frames and single-pane storms that let in half the weather. He learned the trade in the building trades program at Columbus State, and he’s been measuring and setting windows and doors in central Ohio for close to three decades now. He’s the kind of installer who shows up having already looked at the satellite view of the house, knows which side takes the afternoon sun, and brings a level he trusts more than the sill. That’s the standard we bring to every CGI service call in Jacksonville.
We also know what the salt air does to hardware in this city. Jacksonville’s coastal exposure through the Atlantic beaches and the St. Johns River estuary means aluminum frames oxidize and hardware seizes faster here than in inland Florida cities. Our technicians have pulled enough corroded rollers and gearboxes out of Jacksonville homes to know what fails, what can be saved, and what needs the full frame replaced. We carry the right parts so most jobs get done in one visit, and we quote side by side on paper so you see exactly what you’re buying.
Common CGI Windows & Doors Problems We Solve in Jacksonville
- Salt-air corrosion at the bottom weep slots of Sentinel casement frames. This is the number one CGI failure we see in Jacksonville. The weep slots on Sentinel casements are designed to drain water, but in Jacksonville’s salt-laden atmosphere, they clog and hold moisture against the stainless steel screw bosses. Left alone, those bosses corrode and the frame hardware starts to fail. We clean the weep path, replace corroded bosses, and treat the channel so it drains the way it was designed to.
- Estate Collection double hung tilt-latches that won’t hold. Jacksonville’s humidity cycles and salt air work on those tilt-latch mechanisms until they stop engaging entirely. The sash suddenly won’t stay open, or it drops when you try to clean it from inside. We replace the latch assemblies with OEM parts and check the balance springs at the same time, because in this climate the two usually go together.
- Classic Series slider track wear at the interlock meeting stile. These older sliders, common in 1980s and 1990s Jacksonville homes in Mandarin and Arlington, wear at the point where the two sashes meet. Once the interlock wears down, air infiltration becomes bad enough to fail Jacksonville’s blower-door tests for wind mitigation credits. We rebuild the interlock with stainless steel rivets and replace the worn track, which often saves the frame and passes the inspection.
- Seized multi-point locking gearboxes on Estate impact doors. The factory grease in those gearboxes dries out in Jacksonville’s summer heat. The deadbolt turns halfway and jams, and suddenly you can’t lock your front door. We open the gearbox, clean out the old grease, re-lubricate with a high-temp spec, and replace any worn internal gears. Most gearboxes don’t need full replacement, just proper cleaning and the right grease.
- Failed glazing seals from subtropical humidity and intense afternoon storms. Jacksonville’s daily summer storm season tests every seal on your windows. When an older CGI unit loses its seal, you’ll see condensation between the panes or fogging that won’t clear. We can reglaze units that are still structurally sound, and when the frame is square and corrosion is limited to the sash channel, we’ll tell you that before we suggest replacement.
CGI Service in Jacksonville: What Local Conditions Mean for Your Equipment
Here’s something most contractors don’t explain, and it matters a lot for CGI owners in Jacksonville. Jacksonville is the largest city by land area in the contiguous U.S., and the Florida wind-borne debris region boundary cuts right through Duval County. A CGI Sentinel impact casement installed in Atlantic Beach must meet a 130+ mph wind-load rating, period. The same window in a Mandarin ranch just a few miles inland only requires a standard wind-load certificate. That’s not a small difference in cost or in permitting. We do a free zone audit before any quote, because we’ve seen too many Jacksonville homeowners pay for impact glass they were never required to buy, and too many others fail a final inspection because nobody checked the zone boundary before the job started. If the pane is not true, the job is not done, and if the zone is not checked, the permit is not complete.
That zone split also affects which CGI products make sense where. Beachside homes in Jacksonville Beach and Atlantic Beach generally need full impact-rated openings. Homes in Southside, Baymeadows, or Westside often don’t. The point is, you should know which side of the line your house sits on before anyone quotes you a window. We check it, we show you the map, and we quote accordingly.
CGI Models & Products We Service in Jacksonville
We service the full CGI line that shows up in Jacksonville homes and a few that show up in the older housing stock from the 1960s through the 1990s. That includes the CGI Sentinel Series, the impact-rated casement and picture windows common in beachside neighborhoods like Jacksonville Beach and Atlantic Beach. We also work on the CGI Estate Collection, the aluminum-clad wood double hungs found in a lot of Riverside and Avondale historic homes, and the CGI Classic Series, the non-impact single hungs and sliders that dominate the original single-pane aluminum era of Southside, Mandarin, and Baymeadows ranch homes. For our Door Installation in Jacksonville, we service CGI Estate Custom Doors, including hinged and French impact doors.
On parts, we stock OEM CGI rollers, balances, and locking gearboxes for Sentinel and Estate lines. For older Classic Series hardware, we use American-made aftermarket parts that match the original specifications, because some of those original parts are no longer produced by the factory. We also stock the stainless rivets and flashing materials we need for the salt-driven corrosion repairs we do all over Jacksonville.
CGI Service Pricing in Jacksonville

|---|---|---|
| Tilt-latch replacement (Estate double hung) | $85-$155 per sash | Parts availability, sash weight |

What drives the cost in Jacksonville is the zone rating. An impact window for Atlantic Beach costs more than the same window for Mandarin because of the wind-load requirements. Our free estimate comes on paper, with the zone audit done first, the part numbers listed, and the labor broken out. No change orders, no surprise line items. Call (888) 635-0804 and we’ll walk you through what your home actually needs.

FAQs - CGI Windows & Doors in Jacksonville
My CGI Sentinel casement window in Jacksonville Beach is hard to crank after every nor’easter. Is that normal?
It’s common, but it’s not something to ignore. Salt spray from nor’easters leaves a film on the hinge tracks and crank gears of Sentinel casements, and over time that film hardens and makes the operator work harder. We clean the hardware, replace worn crank gears, and lubricate the pivot points with a marine-grade compound that holds up in Jacksonville Beach conditions. If it’s already binding badly, call (888) 635-0804 and we’ll quote the repair.
Why does my CGI Estate double hung in Riverside keep falling shut when I try to leave it open a few inches?
The tilt-latch mechanisms in Estate double hungs fail after repeated salt-laden humidity cycles in Jacksonville. Riverside’s pre-WWII wood-frame homes hold more humidity than newer construction, and the latches stop engaging. When they let go, the balance springs can’t hold the sash. We replace the latch assemblies with OEM parts and check the balance springs, because once the latches fail, the springs are usually underload. Most of these are same-day repairs.
Can you make my 1990s CGI Classic Series sliders pass Jacksonville’s wind mitigation inspection without replacing them?
Usually yes, if the frame is still square and the interlock meeting stile is the main problem. The track wear at the interlock is what causes the air infiltration that fails the blower-door test. We rebuild the interlock with stainless steel rivets, replace the track, and re-flash the rough opening as needed. We’ve done this on 1980s ranches on San Jose Boulevard in Mandarin, and those homeowners passed the same week. If the frame is racked or the glass is loose in the channel, replacement becomes the honest recommendation. Call (888) 635-0804 for a free assessment.
My CGI Estate French door in Avondale has a multi-point lock that turns halfway and jams. Is the door warped?
The door probably isn’t warped. The factory grease in the multi-point gearbox dries out in Jacksonville’s summer heat, and the internal gears bind. Once cleaned and re-lubricated with high-temp spec, most gearboxes work like new. If the door slab has shifted from Avondale’s older framing, we check that too, but the gearbox is the first thing we inspect. Estimates are free, and most repairs are same-day.
Do you stock CGI impact glass for older Sentinel custom arch windows, or do I have to order from the factory?
For custom arch shapes, we don’t keep glass sitting on a shelf, because every arch radius is different. What we do is order directly from the CGI factory for exact-match impact glass, and we handle the permitting and inspection paperwork for Jacksonville’s wind zone requirements. The lead time varies, but we’ll give you a written delivery window and register the warranty in writing before the truck leaves your driveway. Call (888) 635-0804 to get the order started.
