CGI Windows & Doors in Miami, FL

CGI Windows & Doors in Miami, FL | TruePane Windows & Doors

We’re an independent CGI service provider, not a manufacturer-authorized dealer, and we work throughout Miami-Dade County on impact windows and doors that were installed as far back as the early 2000s and are still under their original frames, including CGI repair in Coral Gables. What separates our CGI work in Miami from every other shop is a simple fact: we template every rough opening against the product’s Miami-Dade NOA number before we ever write a purchase order. Most Miami homes built before 1970 have jalousie rough openings under 30 inches wide, and a standard 30-inch CGI impact casement will not carry a valid NOA label in that pocket.

Why Miami Residents Choose Us for CGI Service

Dale Kessler grew up in Seminole Heights back when the neighborhood was more bungalows and screen porches than craft cocktail bars, and he never really left. He picked up the glazing trade at Hillsborough Community College’s construction technology program, spent more time on the shop floor than in a classroom seat, and has spent the better part of two decades measuring, setting, and sealing windows and doors. The work he’s best known for is storm-rated installation done tight enough that a follow-up inspection is never a surprise. That matters in Miami, where a county inspector’s first stop is the NOA sticker.

Our crew is in Miami-Dade County daily and holds no manufacturer authorization from CGI, but we know the NOA-numbered product families in their line and what fails in salt air, thermal cycles, and HVHZ wind tests. We match every replacement to the rough opening and existing anchor pattern rather than just selling a new window. If it needs to be in writing to be true, we will put it in writing.

Common CGI Windows & Doors Problems We Solve in Miami

• Bottom rail in-weep corrosion from salt air and sprinkler overspray. Miami homes with reclaimed water systems see pitting appear in 6 to 8 years on east- and south-facing exposures. The weep holes clog, water backs up into the track, and the frame starts eating itself from the inside out. We clean the weeps, restore the drainage path, and replace corroded rail sections when the extrusion still has structural integrity.
• Hollow bulb gasket compression set on high-rise balcony sliders. Repeated thermal expansion on Biscayne Bay exposures flattens the gasket until air and water push through the interlock. We replace the gasket with the correct durometer for the opening and reset the interlock tolerances so the panel seats square.
• Roller track pitting and stick-slip on CGI sliding glass doors. Where builder-grade stainless was never installed, metal-on-metal wear accelerates in salt-laden wind, and the door starts to fight you. We swap in genuine CGI roller assemblies and address the track scoring rather than masking it with lubricant.
• Perimeter structural silicone release at jamb flanges in older CBS walls. Mortar pockets that were never fully filled allow the substrate to move, and the silicone eventually lets go at the flange. This is common in Little Havana and West Miami, where coral-rock in-fill sills sit behind original jalousie frames. We pull the trim, re-anchor, and reseal.
• Impact glass stress cracks at corner dade-lite cutouts. When a prior installer over-shimmed the frame into a non-square rough opening, the glass carries load it was never designed to carry. The crack starts at the cutout corner and runs. That’s a full sash replacement, and we square the opening before the new sash goes in.

CGI Service in Miami: What Local Conditions Mean for Your Equipment

Miami-Dade County is a High Velocity Hurricane Zone. That means every window and door replacement, even a simple swap, must use products carrying a Miami-Dade Notice of Acceptance, a county-specific product certification more stringent than the standard Florida Building Code and unlike any requirement in Orlando, Tampa, or Jacksonville. This intersects with South Florida’s property insurance crisis: many carriers now demand proof of impact-rated openings or outright refuse to write policies on homes without them. An Miami Window Installation upgrade is a financial necessity, not just a safety upgrade.

Here’s the part most out-of-state crews miss: the Miami-Dade NOA sticker is the job’s gatekeeper. Inspectors will fail a rough inspection if the product’s NOA number isn’t posted on-site and verifiable in the county’s online product approval database. Contractors who arrive with Florida-statewide-approved products that still don’t meet the HVHZ standard get caught at this exact step, and it routinely surprises newcomers to the market. Our templating process checks every opening before we write the purchase order, because a failed inspection means a second truck roll, a second permit fee, and a homeowner left with a tarp over their window for another week.

CGI Models & Products We Service in Miami

We service the full CGI impact line that gets installed in Miami-Dade: the Sentinel Impact Casement, the Estate Impact Single and Double Hung, the 7000 Series Fixed and Picture, and Custom Radius/Arched Impact units. We use genuine CGI replacement components when the frame is intact and only the sash, roller, or lock set is damaged. The extruded profiles are not easy to match aftermarket, and we won’t pretend otherwise. When the frame shows deep aluminum oxidation or moved anchors, we push a full-frame replacement before the opening fails a wind-driven rain test. Every replacement sash gets matched to the rough opening and the existing anchor pattern, not the other way around. Our CGI sales & service work includes hurricane impact windows, wind mitigation and code compliance, and impact sliding glass doors.

FAQs - CGI Windows & Doors in Miami

Do CGI impact windows sold in Miami need a separate Miami-Dade NOA sticker, or is the Florida Product Approval enough?
They absolutely need the Miami-Dade NOA, and a Florida Product Approval alone will not pass a county inspection. Miami-Dade is a High Velocity Hurricane Zone with its own product certification process, and inspectors verify the NOA number against the county’s online database at rough inspection. If the sticker isn’t posted and the number doesn’t check out, the opening fails. Call (813) 320-9346 and we’ll check your existing NOA numbers before any work begins.

How do I know if my original windows are jalousie and what happens when one is pulled out in a CBS wall?
Jalousie windows have horizontal glass slats that crank open like louvers, and they’re common in pre-1970 Miami homes from CGI service in Hialeah to West Miami. When we pull one from a concrete block structure wall, we’re dealing with narrow rough openings, often under 30 inches wide, and masonry pockets that were never framed square. The jamb needs re-anchoring, the sill needs leveling, and the opening often needs a custom-sized impact casement to carry a valid NOA. It’s a templating job first, not a stock swap.

Can a standard 30-inch CGI impact casement be installed into an old Miami jalousie opening?
Usually no, and this is one of the most common mistakes we see from crews that drive in from Broward or Tampa. The original jalousie rough opening is frequently narrower than 30 inches, and the NOA label and anchoring flange won’t line up with the existing masonry pocket. We order CGI custom impact casements to a 1/4-inch net clear width so the NOA stays valid. Call (813) 320-9346 before you order anything, and we’ll tell you exactly what your openings require.

Why does my CGI sliding glass door roller look pitted after only five years on a Biscayne Bay exposure?
Salt-laden wind carries chlorides that settle into the track, and when the roller assembly was never upgraded to stainless, metal-on-metal wear accelerates until the door starts to stick. Five years on a direct bay exposure is not unusual for a builder-grade track. We replace the rollers with the correct stainless assembly and address any track scoring while we’re in there, because lubricant won’t fix pitting.

Will my insurance carrier accept a CGI impact window replacement if the NOA number is from an older CGI model that is still in production?
Yes, as long as the NOA number is verifiable in Miami-Dade’s online database and the product is still in production or has a valid current approval. We photograph the NOA sticker on the interior jamb after every install and provide that documentation for your insurance file. Many carriers in Miami now re-quote policies with a windstorm premium reduction after a verified NOA-compliant impact window replacement. Call (813) 320-9346 to have your current openings assessed.
