Repair pricing runs roughly $125 to $400 for common CGI issues, and full replacements in South Miami start around $1,500 per opening depending on the series and glass package.

This page is written for homeowners in South Miami who already own CGI impact windows and need honest answers about whether to repair or replace them, what it should cost, and who in this area actually knows the product. We are an independent CGI service provider, not a manufacturer affiliate. Ed Winslow has been installing and repairing impact windows across South Miami since 2011, and he grew up in the Sunset neighborhood near Dante Fascell Park, so he knows exactly what these windows are up against here.
How CGI Products Fail - and How We Fix Them
CGI makes a solid impact window. That said, we see the same failure patterns repeat across South Miami homes year after year. Here is what actually goes wrong and how we address it.
- Fogged or hazed glass on CGI Estate and Targa series. South Miami’s humidity attacks the desiccant strip inside the insulated glass unit. Once that strip saturates, condensation forms between the panes and the window looks permanently dirty. The glass unit is done, but the frame is usually fine. We replace just the IGU, which costs a fraction of a full window replacement and keeps the original CGI frame warranty intact.
- Binding or dragging sashes on CGI Sentinel horizontal rollers. The Sentinel series uses roller assemblies that collect grit and salt film faster than most people realize, especially on homes within a few miles of the coast in South Miami. When a roller wears flat or the track gets scored, the panel stops gliding and eventually seizes. We clean and resurface the track, then install new OEM-spec rollers. Aftermarket rollers are available, but we use CGI hardware because the tolerances matter on a window rated to take a hurricane impact.
- Water intrusion at the frame corners on older CGI Estate installations. This is rarely a window problem. It is almost always an installation problem. The original installer skimped on flashing or used a sealant that hardens and cracks after a few South Miami summers. We pull the interior trim, inspect the rough opening, re-flash the perimeter, and reset the window. That fixes the leak at the source instead of smearing caulk over the symptom.
- Cloudy lamination in the interlayer on CGI windows exposed to full western sun. The laminated glass in CGI impact products is built to take a hit, but South Miami’s afternoon sun is relentless. On windows that face west with no overhang, the outer glass gets hot enough that the laminate can begin to show a milky haze at the edges. If it is caught early, the glass may still pass impact testing. If not, the unit needs replacement. We inspect the laminate up close and give you a straight answer about whether the window is still doing its job.
- Hardware loosening on CGI Targa casement operators. Crank-out windows from the Targa line use a worm-gear operator that works loose over time, especially when the window is opened daily during South Miami’s dry season. The crank turns but the sash barely moves, or it slips. It is a simple fix: we remove the operator, replace any worn gears with OEM parts, and re-lubricate the assembly with a marine-grade grease that holds up to humidity. No need for a new window.
Our CGI Impact Windows Process
Here is exactly how a CGI job goes when you call Winslow Windows & Doors in South Miami.
- 1
You call (850) 930-1813. A live person answers, not a call center. We ask what the window is doing, which CGI series you have if you know it, and when you first noticed the problem. Then we schedule a time that works for you.
- 2
We show up and diagnose. Ed or one of our background-checked technicians arrives in uniform, introduces themselves by name, and inspects the window. We check the glass, the frame, the tracks, the rollers, the hardware, and the flashing around the opening to find the actual root cause, not just the visible symptom.
- 3
You get a written line-item quote. We tell you what is wrong, what we recommend, and exactly what it costs before any work begins. If you already have a written estimate from another company, we will give you a free second opinion on it.
- 4
We make the repair or replacement. For parts, we use CGI OEM components whenever possible, because that is what a CGI window was engineered around. When OEM is unavailable or the window is old enough that OEM has been discontinued, we source quality aftermarket parts that match the original spec and tell you upfront which one we are using.
- 5
We test the window. After repairing or replacing, we cycle the window several times, check the seal, and confirm the panel sits square in the frame. On replacements, we verify the installation is flush, level, and properly flashed.
- 6
We stand behind it. Every job is covered by our Done Right Promise. If it is not done right, we come back and make it right. That is our word, and Ed’s name is on the truck.
What CGI Impact Windows Cost in South Miami
CGI repair costs in South Miami depend on what failed, not on what the window is worth. Here is what we typically see:
- IGU replacement for fogged glass - $150 to $400 per unit, depending on size and whether the glass is clear or tinted.
- Roller replacement and track service on Sentinel sliders - $125 to $250 per panel.
- Casement operator replacement on Targa windows - $140 to $220 per window.
- Flashing repair and window reset for corner leaks - $250 to $600 per window, depending on how much trim has to come out.
- Full CGI replacement - $1,500 to $4,500 per opening, depending on the series, size, and glass package.
What moves the price on a replacement is the CGI series you choose, the size of the opening, and whether you need a custom frame color or a specialty glass package. We quote fixed pricing with no change orders. Every estimate is free. Call (850) 930-1813 and we will give you a real number, not a ballpark.

FAQs
Replacing just the insulated glass unit on a fogged CGI window in South Miami typically costs between $150 and $400 per unit, depending on size and glass tint. The frame usually does not need to be replaced unless it is cracked or bent. Call (850) 930-1813 for a fixed quote, with no obligation.
We use CGI OEM parts whenever they are available, including roller assemblies, operators, and hardware. On older CGI lines where the manufacturer has discontinued certain components, we source aftermarket parts that match the original engineering spec and tell you exactly which one we are installing before we start.
No, repairing a CGI window with OEM parts does not void the manufacturer warranty. In fact, replacing just the glass unit and keeping the original frame usually preserves more of the warranty than swapping the entire window out for a different product. An independent CGI service provider like Winslow Windows & Doors can handle repairs without affecting your coverage.
Most CGI diagnostics in South Miami are completed within one business day of your call, and repairs are frequently done on the same visit once parts are confirmed.
