CGI Windows & Doors in Key Largo, FL | TruePane Windows & Doors
TruePane Windows & Doors provides independent CGI service across Key Largo, from North Key Largo down through the Tarpon Basin neighborhoods. We’re not the factory and we don’t pretend to be – we’re the crew that rebuilds, reseals, and replaces CGI impact units after the island’s salt air has done what salt air does. The thing that makes our CGI work different here is simple: we know which components fail first on this island specifically, and we stock the marine-grade parts to fix them right. Call (448) 428-7290 for a free estimate, and a live person will answer.
Why Key Largo Residents Choose Us for CGI Service
Key Largo sits on a strip of land roughly two miles wide with the Atlantic on one side and Florida Bay on the other. Nearly every home here catches salt air from multiple directions at once. That changes how CGI windows and doors age, and it changes how they need to be serviced. Our crews have rebuilt enough CGI Sentry, Estate, Targa, and Panorama units on canal-front homes to know where the factory’s coastal corrosion resistance ends and Key Largo’s marine environment begins. Dale Kessler, our owner, grew up just north in Naranja and spent enough summers boarding up windows before hurricane season to decide he’d rather install ones that didn’t need it. He learned the trade at Miami Dade College’s Kendall Campus, and for more than a decade now he’s run TruePane out of Homestead with one rule on the whiteboard: if the pane is not true, the job is not done. That’s the standard we bring to every CGI sales & service call in Key Largo.
Common CGI Windows & Doors Problems We Solve in Key Largo
- Salt creep at Sentry Series casement corners. The aluminum cladding at the meeting rail corners on CGI Sentry Series casements corrodes and swells from the constant salt-laden humidity. In canal-front Key Largo homes we regularly see sashes bind within three to five years of installation. We disassemble the corner, remove the corrosion, and rebuild with marine-grade sealant and hardware so the sash swings clean again.
- Targa Series multipoint locks seizing. The factory dry-film lubricant on the multipoint locking mechanism washes out fast in salt air. When it’s gone, the lock corrodes and the door won’t latch properly. We see this on Targa Series impact doors after the first hurricane season on the water. The fix is a full mechanism cleaning, marine-grade lubrication, and replacement of any pitted internal parts.
- Slider sill pans pulling away from the masonry. Perimeter sealant along the sill pan on CGI impact sliders chalks and separates under constant salt humidity. Wind-driven rain then intrudes at pressures far below the unit’s Miami-Dade rating. We remove the failed sealant, inspect the pan for corrosion, reflash where needed, and reseal with marine-grade product.
- Estate Collection hinge screws streaking with black oxide. Factory stainless hinge screws on Estate Collection swing doors show black rust streaks within 18 months in Key Largo’s dual-ocean exposure. The doors become hard to adjust or remove. We replace the screws with true marine-grade stainless and address any pitting on the hinge plates themselves.
- Fused original aluminum jalousie frames. Older CBS cottages throughout Key Largo still have original jalousie or single-pane aluminum sliders whose frames have corroded and essentially fused to the masonry over 40 to 50 years. Replacement crews need core drills and custom pressure-treated bucks to extract these frames before a new impact unit can be anchored. This demolition scope rarely comes up on mainland jobs, and it’s work we do regularly here.
CGI Service in Key Largo: What Local Conditions Mean for Your Equipment
Key Largo is the only Florida Keys island where U.S. Highway 1 and the only two public schools all sit within 500 feet of open ocean frontage on the Atlantic side. What that means in practice is that a large share of CGI window replacements here are for 1950s-to-1970s CBS homes that must meet Monroe County’s most exposed wind zone. The original aluminum jalousie frames on those homes didn’t corrode gradually; they fused chemically to the concrete block over decades of salt exposure. Our crew spent three days last spring on a 1962 CBS cottage on Tarpon Basin Drive where the original jalousies had corroded so badly the frames had to be core-drilled out in chunks before we could complete a Key Largo Window Installation with new CGI Sentry Series fixed and casement impact windows. The sill pans were so pitted from forty years of Florida Bay salt air that we custom-flashed every opening with a pressure-treated marine-grade buck, then pressure-tested the assembly to 150 mph before signing off. That’s the reality of CGI work in Key Largo: you’re not just swapping glass, you’re rebuilding openings that the salt has been eating for half a century.
CGI Models & Products We Service in Key Largo
We service all four major CGI product lines: the Sentry Series impact windows, Estate Collection impact windows, Targa Series impact doors, and Panorama Series sliding glass doors. For hardware, we stock both genuine CGI factory replacement parts and marine-grade aftermarket stainless counterparts. Here’s our straight answer on repair versus replace: if the frame is still square and the glass lite intact, we rebuild the unit with upgraded marine seals and hardware. If the frame shows through-corrosion or glass seal failure after 15-plus years in salt air, replacement is cheaper than chasing leaks. We’ll quote it both ways on paper so you can see exactly what you’re buying.
CGI Service Pricing in Key Largo
CGI window and door service in Key Largo typically runs between $180 and $650 for component rebuilds like lock mechanisms, hinge replacements, and sealant work. Full frame replacements with new CGI impact units start around $2,400 per opening for standard sizes, with larger sliders and custom bucks running higher depending on the scope of the demolition. What drives the price here is the marine environment: reflashing sill pans, custom pressure-treated bucks for fused frames, and marine-grade hardware all add labor that mainland bids don’t account for. Our free estimates include a written line-item breakdown, and we register both warranty layers in writing before the truck leaves your driveway. Call (448) 428-7290 for an exact quote.

FAQs - CGI Windows & Doors in Key Largo
Key Largo’s dual-ocean exposure means every CGI unit gets salt air from the Atlantic and Florida Bay at the same time, with no land buffer on either side. Miami Beach gets salt too, but it’s a wider landmass with more building density to break the wind. Here, the salt load concentrates on frame corners, threshold drains, and hinge plating much faster. That’s why we recommend marine-grade sealant inspection every two years on Key Largo CGI windows, versus every three to four on the mainland. Call (448) 428-7290 to schedule a look – estimates are free.
Yes, and it’s a job we do regularly. The original jalousie frames on 1950s-to-1970s CBS cottages often can’t be pulled out intact; they have to be core-drilled out in chunks. Then we install a pressure-treated marine-grade buck, anchor it to the masonry, and set the new CGI impact unit into that. It’s more work than a standard retrofit, but it’s the only way to get a proper anchor and seal in a Key Largo coastal home. Call (448) 428-7290 for a quote.
The glass and frame are fine, but the multipoint locking mechanism is the weak point. The factory dry-film lubricant washes out in salt air, the internal parts corrode, and the door stops latching properly. It’s fixable. We clean the mechanism, replace any pitted parts, and lubricate with marine-grade product. We recommend doing that every 12 to 18 months on canal-front homes, and we’ll show you what to check.
In most cases, a leaking CGI slider can be repaired. The usual culprit in Key Largo is perimeter sealant along the sill pan that has chalked and pulled away from the masonry under constant salt humidity. We remove the failed sealant, inspect the pan for corrosion, reflash if needed, and reseal with marine-grade product. If the frame itself shows through-corrosion or the glass seal has failed, replacement makes more sense than patching. We’ll tell you which one you’re looking at. Call (448) 428-7290 for a free estimate.
Yes. Monroe County requires permits for any window or Key Largo Door Installation that changes the opening or the product’s wind rating, and that’s nearly every CGI impact upgrade in Key Largo. We pull the permits and handle the inspections. The paperwork is part of the job, not an extra you’re left to sort out. Call (448) 428-7290 to talk through your project.
