CGI Windows & Doors Service Nationwide | TruePane Windows & Doors

Why Stuart Homeowners Choose CGI Windows & Doors

CGI windows and doors are built in Miami for Florida’s wind-borne debris zones, and Stuart sits squarely in that requirement, so we service and install them constantly. TruePane Windows & Doors provides independent CGI repair, parts replacement, and new installation throughout Stuart, FL, from the historic downtown grid to the river-facing CBS neighborhoods along the St. Lucie. We are an independent CGI service provider, not a factory-authorized dealer, which means we answer to you and the building code before we answer to a manufacturer’s parts catalog. If your CGI SentinAI or Estate Collection unit is fogged, binding, or failing at the hardware, call (754) 324-4646 and we will tell you honestly whether it is a repair or a replacement.

What most Stuart homeowners do not learn until after a failed unit is that CGI’s product line has specific, repeatable failure patterns in this coastal corridor. We know them because we see them every week. Salt aerosol off the St. Lucie Inlet gets into hardware, seals, and balances faster than any manufacturer’s generic brochure admits, and the fix depends on knowing exactly which series you have and which component failed first.

Why Trust TruePane Windows & Doors for Your CGI Windows & Doors?

Dale Kessler grew up in Rio, just south of Stuart along the St. Lucie River, where his father spent thirty years as a glazier before handing Dale his first glass cutter at fourteen. He completed his building construction coursework at Indian River State College in Fort Pierce, then spent the better part of two decades measuring, setting, and sealing windows and doors up and down the Treasure Coast before opening TruePane. He is known around Martin County for reading a rough opening correctly the first time and for not upselling a homeowner on glass they do not need.

Our technicians have hands-on field experience across CGI’s impact-rated product lines, from the Windows 7000 Series to Estate Collection entry systems, servicing Stuart’s coastal corrosion zone without ever relying on manufacturer authorization. That last part matters. As an independent CGI service provider, we stock and source parts based on what actually holds up in Stuart’s salt air, not what the factory catalog defaults to. We use new-old-stock OEM balancers, rollers, and sash locks when available, but we do not hesitate to fit marine-grade aftermarket weatherstripping or stainless hardware where it outperforms factory parts. Every job is backed by the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves the driveway. If the opening is right, the rest is just doing the work.

Common CGI Windows & Doors Problems We Fix in Stuart

Here are the brand-specific failures we see most often in Stuart, and what actually causes them.

• Fogging between panes in SentinAI S350 units. The SentinAI S350 is CGI’s premium impact casement and picture-window line, and its insulated glass units carry a seal that fails prematurely when salt aerosol works into the spacer. A fogged S350 is not a cleaning problem. It is a dead seal, and the only correct fix is replacing the insulated glass unit, not wiping it down. We handle that repair regularly without pulling the entire frame.
• Interlock wear on Targa Series horizontal rollers. The Targa Series sliding doors use an interlocking rail design that is excellent for wind resistance but unforgiving when the roller bearings corrode. In Stuart’s riverfront neighborhoods, we routinely see Targa doors that stick, drag, or derail entirely because the factory rollers were not marine-grade. We replace them with stainless aftermarket rollers and the door glides again.
• Failed balance springs in Windows 7000 Series double-hung sashes. The 7000 Series double-hung relies on coil or spiral balances that cycle thousands of times in a coastal wind environment. Stuart gets sustained pressure cycles that inland Martin County never sees, and those balances lose tension or snap. A sash that slams shut or will not stay open usually means a failed balance, not a broken lock.
• Warped door slabs on Estate Collection entry doors. The Estate Collection is CGI’s heavy, decorative impact entry line, and in Stuart’s humidity the door slabs can swell and warp if the original finish was not sealed on all six sides. A warped slab hangs crooked, binds at the top corner, and compromises the weather seal. We re-plane, re-seal, or replace the slab depending on how far the warp has gone.
• Corroded crank gears and operators on casement windows. CGI casements, especially SentinAI units near the inlet, chew through factory crank operators because the aluminum gear teeth oxidize in salt air and strip under load. The crank turns but the sash does not move. We replace the operator with a stainless aftermarket assembly and lubricate the hinge tracks with a marine-grade compound.

CGI Parts & Our Repair-vs-Replace Approach

CGI still supports most of its Florida-built product lines, but OEM parts availability varies by series and age. We keep new-old-stock balancers, rollers, sash locks, and crank operators for the 7000 Series, Targa, SentinAI S350, and Estate Collection on hand or sourced within days. Where factory hardware has proven weak in Stuart’s salt air, we fit marine-grade aftermarket alternatives: stainless rollers, silicone weatherstripping, and powder-coated operators that outlast the original spec.

The decision to repair or replace comes down to what is still intact. We repair when the frame is square, the glass is sound, and the failure is a part, a seal, or a balance. We replace when the frame extrusion is corroded through, the insulated glass has failed beyond a single sash, or the code upgrade requires a full impact-rated retrofit. We will show you the numbers side by side on paper before we touch a screw. Call (754) 324-4646 for a written quote.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis. We measure the opening, check the frame for corrosion, test the balances or rollers, and verify whether the glass unit is still sealed. On a fogged SentinAI S350, that means confirming the seal failure and checking the sash for structural integrity before we quote anything.
2. 2
   Repair or installation. We remove the failed component, clean the track and frame, and install the replacement part using a marine-grade sealant compatible with CGI’s aluminum extrusions. For full insert replacements on hurricane impact windows, we set the new unit true in the rough opening and shim it before any fastener goes in.
3. 3
   Operational and air-infiltration testing. We cycle every sash, run the door on its track, check the interlocks, and inspect the weatherstripping compression. A window that opens smoothly but leaks air has not been fixed.
4. 4
   Warranty registration and walkthrough. We register both manufacturer warranty layers in writing with durations stated, then walk you through exactly what was done and what to watch for in the first 90 days. If it is not done right, we make it right under the Done Right Promise.

CGI Products We Service & Install in Stuart

We service and install the CGI lines that dominate Stuart’s impact market: the Windows 7000 Series for impact double-hung and sliding windows, the SentinAI S350 for high-end impact casements and picture windows, the Targa Series for impact sliding glass doors, and the Estate Collection for impact entry doors and French doors. We also handle insert window replacement on older CGI frames where the original extrusions are still sound and code-compliant. We keep common balances, rollers, operators, and weatherstripping for these lines stocked locally so most repairs do not wait on a distributor shipment.

We Also Service These Brands

CGI is not the only line we work on. TruePane Windows & Doors is an authorized installer for more than a dozen manufacturer lines, including, and PGT, and we service far more than we install. If your home has mixed brands, we will quote them all on one written estimate and service them under the same Done Right Promise.

FAQs - CGI Windows & Doors Service in Stuart

Why does the glass in my CGI SentinAI S350 look cloudy, and can you fix it without replacing the whole window?

Cloudy glass in a SentinAI S350 means the insulated glass unit’s seal has failed, usually from salt-air exposure working into the spacer. We fix it by replacing just the insulated glass unit and re-sealing the sash, which costs far less than replacing the entire window. Call (754) 324-4646 for a written quote on your specific opening.

My CGI Targa Series sliding door is hard to open - what’s the cause?

Hard-to-open Targa doors in Stuart are almost always corroded or flattened rollers in the interlocking rail track. The door is not warped; the bearings are shot. We replace the rollers with stainless aftermarket units and the door moves cleanly again.

Can you upgrade my CGI Windows 7000 Series double-hung sashes to meet current Florida impact codes?

Yes, if the frame extrusions are still structurally sound. We perform insert window replacement, replacing the old sashes with current-code impact glass units that fit the existing 7000 Series frame. If the frame has corroded through, we will tell you plainly and quote a full replacement.

Do you work on older CGI Estate Collection entry doors with warped slabs?

We do. Warped Estate Collection slabs in Stuart’s humidity are common when the original finish was not sealed on all six sides. We repair the slab where the warp is minor, and replace the slab when the warp has compromised the weather seal. Either way, the door will close square and seal properly.

Are your repairs compliant with Stuart’s wind mitigation requirements?

Yes. Stuart sits in Florida’s Wind-Borne Debris Region at ultimate design wind speeds of roughly 150 to 160 miles per hour along the coast, and every repair or installation we make meets the current code for impact-rated glazing, anchoring, and product approval. We pull permits where required and the inspection passes before we call the job done.

How much does CGI windows and doors service cost in Stuart?

CGI service costs in Stuart depend on the repair: a single failed balance or roller replacement typically runs $150 to $350, an insulated glass unit replacement on a SentinAI S350 runs $400 to $900 per sash, and a full impact insert replacement runs $900 to $1,800 per opening depending on glass package and frame condition. We give a fixed written price before any work begins. Call (754) 324-4646 for an exact quote, and remember the estimate is free.
