CGI Construction in Miami, FL | Penhallow Remodeling Miami
CGI construction service in Miami typically means one thing: impact windows and doors that have to survive hurricane season, salt air, and a county building department that checks everything. We’re an independent CGI service provider, not a factory-authorized dealer, which means we can repair and replace what’s actually failing on your home without pushing a full replacement you don’t need. From Brickell condos to Little Havana bungalows, our crews work on CGI Sentinel Series windows, Estate Collection units, and Targa sliding doors every week. Call (850) 988-7559 for a free estimate, and we’ll give you a number first, then pick up the tools.
Why Miami Residents Choose Us for CGI Service

We’re not the CGI manufacturer, and we won’t pretend to be. What we are is a General Contractor - Miami team that works directly with CGI hurricane-rated window and door systems in concrete-block and CBS homes daily. That matters because Miami-Dade product approvals require matched components, and our techs know which CGI glass packs, rollers, and hardware meet HVHZ requirements without a second guess.
Trevor Nash runs our Miami crew. He learned the trade at Los Angeles Trade-Technical College and has spent nearly three decades managing jobs from Miami Bathroom Remodeling refreshes to full structural overhauls. Trevor’s been working throughout Miami for years, including plenty of projects in Coconut Grove where older homes tend to have a story hiding behind every wall. He shows up with a written estimate before anything else gets discussed, and he’ll be straight with you about what a CGI repair actually involves, including the parts that aren’t glamorous.
Our techs are background-checked, uniformed, and we answer the phone live 24/7. No voicemail maze. We carry OEM-compatible parts where available, and we stock common CGI hardware locally so a Targa roller replacement in Hialeah doesn’t wait on a factory shipment from up north. Every job gets a written price before work starts and a written guarantee when it’s done. See our full CGI sales & service page for more on what we cover.

Common CGI Construction Problems We Solve in Miami
CGI products are built for hurricane zones, but Miami’s particular combination of salt, humidity, and concrete construction creates failure patterns you won’t see in Atlanta or Orlando. Here’s what we handle most often:
- Salt-corroded Targa sliding door rollers. Miami’s salt air attacks the stainless steel roller assemblies on CGI Targa sliding glass doors. The door starts to bind, then jumps the track entirely. We replace the factory rollers and realign the panel before the track itself gets chewed up. If you’re hearing grinding or feeling resistance when you slide the door, don’t force it, it gets expensive fast.
- Plugged interior weep-hole covers. Wind-driven rain and dried salt plug the original weep-hole covers on CGI impact windows. Water puddles inside the frame and stains the drywall below. We clear the drainage path and replace the covers with updated components that shed Miami’s afternoon downpours properly.
- Thermal seal failure on southern exposures. CGI insulated glass units facing strong southern exposure in Miami fog between the panes even without impact damage. The sun load and humidity differential eventually break the seal. We replace the failed glass pack under Miami-Dade approval drawings rather than selling you a whole new window.
- Flange separation on older CBS homes. On 1950s-to-70s concrete block homes, CGI window flanges originally sealed with caulk pull away from the concrete opening. Afternoon thunderstorm water seeps behind the stucco and shows up as interior staining weeks later. We re-flash the opening with butyl tape and polyurethane sealant, then pull the permit update.
- Discontinued hardware without factory support. Older CGI models sometimes have hardware the manufacturer no longer stocks. For discontinued components, we source certified equivalent parts that meet HVHZ requirements. We only recommend full replacement when the frame itself is corroded beyond repair or the glass pack is no longer manufactured.
CGI Service in Miami: What Local Conditions Mean for Your Equipment

Here’s what nobody tells you until the inspector shows up: in Miami, every CGI window job must be permitted under Miami-Dade County’s Notice of Acceptance rules. Our crews routinely pull and close permits showing the exact product approval drawing for your specific CGI unit. Contractors in Broward or Palm Beach don’t face that same county-level rigor. It means a CGI repair in Miami isn’t just a parts swap. It’s a documented, inspected installation that has to match the NOA drawing on file for your exact window or door model. When we replace a glass pack or re-flash a flange, the permit paperwork follows. That’s not bureaucracy for its own sake. It’s the county verifying that the hurricane-rated product protecting your home still meets the wind-load standard it was approved under. Our team handles the permit, the inspection, and the close-out. You shouldn’t have to navigate Miami-Dade’s building department on your own, and with us, you don’t.
Field story: our tech was called to a 1970s CBS home off SW 8th Street in Little Havana because the homeowners’ CGI Sentinel picture window had moisture between the panes and water staining the interior sill. We found the marine-grade sealant at the flange had dried and separated from the concrete block, letting wind-driven rain wick behind the stucco. After replacing the failed insulated glass unit and re-flashing the opening with butyl tape and polyurethane sealant, we pulled the Miami-Dade permit update and the window passed the same-day inspection. That’s how CGI work actually goes in Miami. It’s not just the glass.
CGI Models & Products We Service in Miami
We service the full CGI residential line, including the Sentinel Series impact windows, Estate Collection impact windows, Targa Series impact doors, and 800 Series casement and picture windows. When we replace glass, we use CGI factory replacement glass packs and hardware where available. Miami-Dade product approval requires matched components, so that’s the default. For discontinued hardware, we source certified equivalent parts that meet HVHZ requirements. We stock common CGI rollers, locks, and balance hardware locally for faster turnaround in Miami, so a sliding door repair in Brownsville doesn’t sit waiting on a freight shipment. The difference between OEM and aftermarket matters here, and we’ll explain exactly which part is going in your home and why.
If you’re comparing models for a remodel, the Sentinel line is CGI’s entry-level impact offering, solid but with fewer finish options. The Estate Collection gives you more frame and glass customization, and Targa doors mean a sliding or multi-slide impact door system that holds up to Miami’s salt air when the rollers are maintained. We’ll walk you through the trade-offs in plain language, no catalog-speak. You can also see our Miami service area page for where we work.

FAQs – CGI Construction in Miami
You can absolutely replace just the glass in most CGI impact windows, and that’s usually the right move. As long as the frame is square, not corroded, and the specific glass pack is still manufactured, we swap the insulated glass unit under the Miami-Dade approval drawing and re-seal the frame. The full window only gets replaced when the frame itself is failing or the glass pack is discontinued. Call (850) 988-7559 and we’ll tell you which situation you have before we quote anything.
Yes, we install CGI products in older Miami condos regularly, including buildings in Brickell and Edgewater where association approval is part of the job. We provide the product approval drawings, the Miami-Dade NOA documentation, and the contractor credentials your association will ask for. We’ve worked through enough condo board requirements to know what they’ll request before they ask. The approval process adds time to the schedule, but it doesn’t change the quality of the install. Call (850) 988-7559 and we’ll walk you through what your specific building needs.
After a Miami storm, a stiff CGI sliding door is usually not a warranty issue, it’s salt and debris in the roller assemblies. Wind-driven salt spray and fine sand get into the track and the rollers start to bind. We clean the track, replace the rollers if they’re pitted, and realign the door. It’s a service call, not a new door. If the frame itself was racked by storm surge or impact, that’s a different conversation, and we’ll show you exactly what we found. Call (850) 988-7559 and get it looked at before it jumps the track.
Yes, and this is where Miami kills windows that would be fine in a wood-frame house. Concrete block doesn’t flex like wood, and the original caulked flange on older CBS homes dries, separates, and lets wind-driven rain wick behind the stucco. We re-flash every CGI opening with butyl tape and polyurethane sealant, not caulk. It’s the only way to keep afternoon thunderstorm water out of a block wall. Call (850) 988-7559 for an exact quote, estimates are free.
The Sentinel Series is CGI’s entry-level impact window, built to the same wind-load standard but with fewer frame finishes and glass package options. The Estate Collection gives you more customization: wider frame profiles, more interior and exterior finish choices, and higher-end hardware. For a Miami remodel, Sentinel gets the job done and meets code, while Estate is the line you choose when the windows are a design feature and not just protection. We’ll quote both. Call (850) 988-7559 to compare real numbers for your openings.
