CGI Windows & Doors in Key Biscayne, FL | TruePane Windows & Doors
We’re TruePane Windows & Doors, an independent CGI service provider working across Key Biscayne, FL. We repair, rebuild, and replace CGI impact windows and sliding doors on the island’s condos and ranch homes, and the thing that sets our work apart here is simple: we understand what salt air and HVHZ wind-load rules do to CGI products over time. Call (813) 320-9346 for a straight answer and a free estimate. If it needs to be in writing to be true, we will put it in writing.
Dale Kessler, our owner, grew up in Seminole Heights and learned the glazing trade at Hillsborough Community College’s construction technology program, spending more time on the shop floor than in a classroom. For the better part of two decades he’s been measuring, setting, and sealing windows and doors across Florida’s toughest coastal environments. Our crew works on CGI sales & service daily in Miami-Dade’s HVHZ, including the salt-heavy barrier-island stock of Key Biscayne, so we know exactly which frame, hardware, and seal upgrades survive marine exposure. We’re not the manufacturer and we don’t claim to be authorized by them. We’re the people who keep their products functioning when Key Biscayne’s climate does its worst.
Why Key Biscayne Residents Choose Us for CGI Service
Most Key Biscayne homeowners we meet have lived in their house or condo for twenty years or more, and they’ve watched their original windows slowly give ground to salt and wind. They don’t want a sales pitch. They want a glazier who can look at a fogged CGI Sentinel casement or a salt-jammed Classic 9600 slider track and tell them honestly whether it’s repairable or done. That’s what we do.
Our technicians are background-checked and uniformed. They measure every opening twice. They quote manufacturer lines side by side on paper so you can see exactly what you’re buying. And because we’re local to South Florida, we understand that Key Biscayne service area work means salt corrosion, not just storm damage. We stock the OEM gaskets, rollers, and hardware that keep your CGI products within their original Miami-Dade NOA, and we’ll recommend marine-grade aftermarket stainless when the original parts show early salt creep. If the pane is not true, the job is not done.
Common CGI Windows & Doors Problems We Solve in Key Biscayne
- Salt-creep corrosion on uncoated aluminum frame bottom rails. On Key Biscayne’s older CGI Estate and Classic frames, the uncoated OG-style aluminum bottom rails start pitting within 7 to 10 years of direct ocean exposure. We see this constantly on bay-side and ocean-side elevations alike, and it’s the first thing we check on any service call.
- Fogging and lost argon in older insulated glass units. Constant salt haze and high UV break down the edge seals on CGI insulated glass faster here than almost anywhere else on the mainland. When the argon is gone, you’re losing insulating value and looking at a fogged pane. We’ll tell you whether a sash rebuild makes sense or the unit needs replacing.
- Failing stainless steel hinge screws in impact casements. Ocean-facing CGI Sentinel casements on Key Biscayne develop sagging and misalignment when the hinge screws let go under repeated wind loading and salt exposure. We use marine-grade stainless replacements and rebalance the sash so it closes cleanly.
- Weep-hole blockage from salt crystallization. On bay-side sliders and French doors, salt crystals clog the weep channels and water backs up into the track, then the room. We clear the blockages, rebuild the track when needed, and check the drainage path so it doesn’t recur.
- Jalousie and single-pane slider failure on older ranch homes. The 1960s and 1970s concrete-block ranch homes on Key Biscayne still carrying original jalousie windows and single-pane aluminum sliders are non-compliant with current HVHZ codes. When we do a CGI replacement on these homes, we handle the permit and wind-load paperwork as part of the job.
CGI Service in Key Biscayne: What Local Conditions Mean for Your Equipment
Here’s the thing most mainland contractors miss about Key Biscayne: the entire island sits inside Miami-Dade County’s High Velocity Hurricane Zone, and every structure, regardless of which street it sits on, is within direct salt-spray range of open water on at least one exposure. That means even a simple like-for-like CGI window swap in a 1960s ranch on Hampton Lane must carry a Miami-Dade Notice of Acceptance and pass wind-load calcs for direct ocean exposure on at least one elevation. A shop that mostly works CGI service in Miami might not flag that until the inspection fails. Our standard permit package handles it upfront, because we’ve done it enough times to know the county’s expectations cold.
That’s not bureaucratic trivia. It changes which CGI hardware we recommend. The same aluminum frame that lasts fifteen years in Coconut Grove or Coral Gables CGI service territory can start pitting in eight on Key Biscayne, simply because the wind carries salt farther and the humidity never really lets up. When a condo board or a homeowner on the island asks us to service a CGI Classic 9600 slider or a Sentinel casement, the first thing we’re doing is checking the frame rails, the hinge screws, and the weep channels, all of which fail faster here. On a bay-front condo unit along Ocean Drive, our crew pulled a 1990s CGI Classic 9600 sliding door with a lower track so salt-caked the rollers ground to a stop. We replaced the original steel rollers and track cap with marine-grade stainless, then rebalanced the panel so it closes with one hand. The HOA’s engineer later confirmed the original Miami-Dade NOA for that door still applied after our hardware upgrade.
CGI Models & Products We Service in Key Biscayne
We service the CGI product lines most common on Key Biscayne’s condo buildings and single-family homes: the CGI Sentinel impact casement and fixed windows, the Estate collection aluminum impact sliders and French doors, the Targa series thermally broken impact windows, and the Classic 9600 impact sliding glass doors. For each line, we use OEM CGI hardware and gaskets where available, because keeping the product within its original Miami-Dade NOA matters. But we won’t push OEM-only for trim or fasteners. When original parts show early salt corrosion, we recommend marine-grade aftermarket stainless hardware. You get a square deal: the right part for the environment, not the priciest part in the catalog. We carry a working stock of OEM gaskets, rollers, and stainless hardware locally so most Key Biscayne service calls don’t wait on a parts shipment from the manufacturer.
CGI Service Pricing in Key Biscayne
CGI service pricing on Key Biscayne depends on what we find when we open the unit. A track rebuild with new rollers and stainless hardware runs less than a full sash replacement, and a sash rebuild costs less than a new insulated glass unit. Frame pitting beyond repairable limits means replacement, and we’ll quote you the manufacturer line side by side on paper so you can compare. Our free estimate includes a full inspection of the frame, glass, hardware, and weep system, and a written line-item breakdown before any work begins. We register both warranty layers in writing before the truck leaves the driveway, and every job carries our 90-Day Done Right Promise. Call (813) 320-9346 for an exact quote, estimates are free.

FAQs - CGI Windows & Doors in Key Biscayne
Because the entire island of Key Biscayne sits inside Miami-Dade County’s High Velocity Hurricane Zone, and every elevation, even the bay side, is considered direct-exposure wind-load territory. The NOA is the product approval that proves the window or door was tested to withstand those loads. A CGI window without a current NOA won’t pass a permitted inspection on Key Biscayne, plain and simple. We pull the paperwork before the job starts, not after the inspector flags it. Call (813) 320-9346 and we’ll check your existing units.
Noticeably faster. On Key Biscayne, unprotected aluminum bottom rails on CGI frames typically show visible pitting within 7 to 10 years, versus 12 to 15 or more on inland Hialeah CGI service neighborhoods. It’s the open-water exposure on at least one side of every structure, plus the year-round salt humidity. We recommend marine-grade stainless hardware and, on new CGI installs, the Targa series with thermally broken frames that reduce the corrosion path. Call (813) 320-9346 for a frame inspection and honest estimate.
In most cases we can repair it. Salt buildup jams the rollers and cap, not the door panel itself. We replace the original steel rollers and track cap with marine-grade stainless, clear the weep channels, and rebalance the panel. Full replacement only becomes necessary when the frame bottom rail is pitted through or the glass seal has failed beyond repair. On Ocean Drive we did exactly this with a 1990s CGI Classic 9600, and the HOA’s engineer confirmed the original NOA still applied after our hardware upgrade. Call (813) 320-9346 for an assessment.
Those original 1960s and 1970s windows are non-compliant with current HVHZ codes and cannot be grandfathered during a permitted renovation. So when a Key Biscayne ranch home goes up for sale or through an insurance renewal, the original jalousie windows and single-pane aluminum sliders get flagged. The CGI replacement needs a Miami-Dade NOA and wind-load calcs for direct ocean exposure, which our permit package handles from day one. Call (813) 320-9346 and we’ll walk you through what your specific house needs.
Yes. We pull permits, complete the wind-load calculations, and register both warranty layers in writing before the truck leaves the driveway. It’s part of our standard service on Key Biscayne because we work in the HVHZ daily and we know what the county’s building department expects. No surprise line items, no second appointment left hanging. Call (813) 320-9346 to schedule your free estimate.
