Ed Winslow started this company in 2011 after years of watching Miami installers cut corners on Impact Windows in Miami, and he’s been fixing their mistakes ever since. We’ve worked up and down Miami Beach, through Hialeah and Little Havana, and into the inland suburbs, and we’ve seen just about every failure mode a CGI unit can throw at a homeowner. The good news? Most of it is repairable without a full replacement, and we’ll tell you honestly when it isn’t.
Why Miami Residents Choose Us for CGI Service
CGI makes a genuinely well-engineered impact window. But even the best window in the world behaves differently after ten years of salt spray off Biscayne Bay and 90-degree humidity in July. We’ve spent over a decade servicing specific CGI product lines installed throughout Miami, from Estate Series units in 1950s CBS ranch homes in Westchester to Commercial Series frames in beachfront high-rises. That depth of hands-on time means we diagnose problems faster and we don’t chase ghost issues that don’t exist.
Ed grew up in Miami and trained at Miami Dade College’s Building Construction Technology program before putting his name on a truck. His crew has worked condos near the Faena District and single-family homes just off the boulevard, so when we say we know Miami’s building stock, we mean we’ve been inside it. My name is on every job we do. That keeps me honest.
We answer calls with a live person, 24/7. Not a voicemail, not a call center. When your slider is grinding and hurricane season is two weeks out, you don’t want a ticket number.
Common CGI Windows & Doors Problems We Solve in Miami
- Aluminum frame pitting and white oxidation along the bottom rail and weep holes. On Miami Beach and Sunny Isles Beach, salt-laden air accelerates frame corrosion dramatically. You’ll see white blooming at the weep holes first, then pitting spreads. If we catch it early, we can clean, treat, and reseal. If the frame is corroded through, replacement is the only safe option.
- IGU seal failure and fogging between panes. Miami’s UV load and humidity break down insulated glass seals faster than almost anywhere else in the country. We regularly see CGI units fog within 8 to 12 years here, about twice as fast as inland Florida. A fogged IGU means the gas fill is gone and the insulating value is shot, plus it looks terrible.
- Horizontal roller and sliding track corrosion. CGI 3-lite sliders and horizontal rolling impact windows depend on clean tracks and smooth rollers. Salt air corrodes the roller bearings and tracks, causing sandy grinding. Left alone, the door sticks open, and a door that won’t close and lock isn’t protecting your home during a storm.
- Racked sashes and stiff operation from improperly anchored installs. This one is rampant in Miami’s concrete-block homes. The original contractor anchored the CGI frame with foam and caulk instead of tapcons into the block, and now the sash doesn’t seat square. Wind-load performance drops, and the window no longer seals the way it did on day one.
- Failed or missing Miami-Dade Notice of Acceptance documentation. A CGI unit installed in Miami-Dade without proper NOA paperwork is a problem waiting to surface at resale or insurance renewal. We help homeowners verify what they have and correct what can be corrected.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the thing about Miami that changes everything for CGI owners: we’re the only market in the country still dealing with jalousie windows at scale. Tens of thousands of pre-1970 concrete-block homes in Little Havana and Hialeah still have louvered jalousie glass, and no jalousie window has ever carried a Miami-Dade NOA. That means thousands of Miami homeowners are being told by their insurance carriers that replacing those old jalousies with impact windows is the single biggest line item on their renewal notice. When they make that upgrade, CGI is the product they ask for, and understanding how that transition works from a masonry opening with no wood framing is something we’ve done hundreds of times.
We’re not selling a generic CGI service pitch. We’re telling you how these windows actually age and fail in Miami’s salt-laden, concrete-block, HVHZ reality. That’s information a contractor in Orlando or Jacksonville simply never sees.
CGI Models & Products We Service in Miami
We service the full CGI lineup that’s installed across Miami, including the Estate Series, Estate Collection, Commercial Series, and Sentinel Series. That covers single-hung and casement impact windows, horizontal rollers, 3-lite sliders, and the heavier commercial frames you’ll see on condo buildings along Collins Avenue and Brickell.
Our parts approach is straightforward: we stock OEM-equivalent replacement hardware, weatherstripping, and rollers that match CGI’s original specifications. CGI factory parts are often backordered for weeks, and no Miami homeowner should wait through hurricane season on a backorder. If the frame itself is compromised or the glass pack is failing, we’ll tell you plainly when repair money is better spent on a new unit. We also handle full frame replacements and Miami Window Installation when it’s time.
For anything related to CGI sales & service, we’re your local source in Miami-Dade.
CGI Service Pricing in Miami
CGI service pricing in Miami depends on what’s failed. Here’s what you can expect, based on our work across Miami-Dade:
- Roller replacement and track service on a CGI slider: $180-$340
- Weatherstripping replacement on one window or door: $120-$250
- Full frame service including tapcon anchoring into concrete block: $350-$700
- IGU replacement (fogged glass pack): $400-$900 per panel
- Full CGI Estate Series replacement window, installed: $1,200-$2,600 per opening
What drives the cost is what we find behind the frame: whether the original install used proper anchors, whether the opening needs stucco repair, whether the frame is salvageable. That’s why a free estimate matters. We’ll come out, inspect the unit, give you a written line-item price, and you’ll know exactly what you’re paying for. We offer $40 off any repair over $200, free second opinions on written estimates, no trip charge in Miami-Dade, and a standing 10% discount for seniors and veterans. Call (863) 656-0462 for the exact number, because guesses don’t help anyone.

FAQs - CGI Windows & Doors in Miami
Yes, if it’s installed correctly into the block opening with the right anchoring and the right Miami-Dade NOA documentation. The concrete-block construction itself isn’t a barrier. What fails inspections is sloppy installation: drywall screws into block, no aluminum buck, caulk and foam instead of tapcons. We see it constantly. A proper install into masonry is entirely code-compliant, and we’ve corrected more bad installs than we can count. Call (863) 656-0462 if your inspector flagged something and you want a second look.
Yes, unfortunately. On Miami Beach, Bal Harbour, and Sunny Isles Beach, salt spray pitting on aluminum frames within 5 to 7 years is common, especially on lower floors closer to the water. It doesn’t mean the window is junk. It means the frame coating is failing and needs treatment before the corrosion deepens. We can clean, treat, and protect the frame, or replace hardware that’s already compromised. Call (863) 656-0462 and we’ll assess it in person.
Yes, and that’s one of our most common repairs in Miami. Salt air corrodes the rollers, and they start grinding against the track until the door sticks. We replace the rollers with OEM-equivalent parts that match CGI’s original spec, clean and lubricate the track, and realign the door. You don’t need a new door because the rollers are shot. Call (863) 656-0462 and we’ll get it sliding smoothly again, usually in one visit.
Yes, we can service unpermitted CGI windows. The permit issue is between the homeowner and Miami-Dade County, but the window itself can still be repaired or replaced. That said, unpermitted impact windows are a real liability at resale and insurance renewal. We can pull the proper permit and do the work right, which is often the fastest way to clear the problem. Call (863) 656-0462 and we’ll lay out your options without pressure.
Mostly yes, as long as the units still seal properly and the frames aren’t compromised. CGI windows installed in 2005 were built to Miami-Dade HVHZ standards of that era, and the core impact glazing remains valid. The issue is whether two decades of salt exposure and UV have degraded the seals, hardware, and frame integrity. If your windows still fog-free and operate smoothly, they’re likely fine. If they’re pitted, stiff, or fogged, they need service or replacement. Call (863) 656-0462 for an honest assessment.
