This page is written for Miami homeowners who already have CGI windows or are considering them, and who want straight answers about how these specific products hold up in our salt air and hurricane cycles. We’re not a CGI call center, and we don’t work for the manufacturer. We’re the local crew that fixes what Miami’s climate does to them.

How CGI Products Fail — and How We Fix Them

CGI builds a solid impact window. But after enough Miami summers, every product line shows its age in specific ways. Here’s what we see most often when homeowners call us about CGI units:

• Sash balance failures on Estate Collection single-hung and double-hung units. These windows rely on spiral or block-and-tackle balances to hold the sash open. In coastal Miami neighborhoods like Brickell and Key Biscayne, salt-laden air corrodes the balance springs faster than inland. The symptom is a sash that slams shut or won’t stay up. We replace the balance with OEM-spec hardware rather than greasing it, because grease hides the problem for about three months and then you’re calling us again.
• Roller wear on Estate and Targa sliding glass doors. CGI sliding doors are heavy, often 200 pounds or more per panel. Miami’s fine limestone dust and construction grit get into the roller tracks and chew up the nylon wheels. Homeowners in Coral Gables and Pinecrest with older paver driveways tend to see this sooner, because the dust from pavers tracks in on shoes and finds its way to the track. We replace the rollers and, critically, we realign the panel so the weight sits evenly. Skipping the alignment is how a new roller set fails inside a year.
• Weep hole clogging on fixed and casement CGI frames. CGI frames drain through small weep channels, and in Miami those channels collect everything from pollen to lovebug carcasses to salt crust. When they clog, water pools inside the frame track after heavy rain, and over time that leads to corrosion at the frame corners. We clear the weeps and treat the channels, and if the corner seals have begun to fail, we re-bed the glass rather than pretending the window is fine.
• Fogging between panes on older CGI 8700 Series and Sentinel insulated units. Double-pane impact glass has a desiccant inside the spacer bar that absorbs moisture. Once that desiccant is spent, usually after 12 to 18 years in Miami’s humidity, you get condensation between the panes that won’t wipe off. We replace the insulated glass unit rather than the whole frame. It’s roughly half the cost of a new window and keeps the original CGI frame in service.
• Crank operator stripping on Estate casement and awning windows. The gears inside the operator wear down, especially on windows that face strong afternoon sun and get opened daily. The handle spins but the sash doesn’t move. We replace the operator with a matching OEM or equivalent aftermarket unit and adjust the arm so it doesn’t bind. Two hours on site, and the window opens like it should.

Our CGI Impact Windows Process

Here’s how a typical CGI job runs with us, from first call to final cleanup:

1. 1
   You call (844) 901-4551. A live person answers. We talk through what you’re seeing, and if it’s a repair, we schedule a time that works for you. No voicemail tag.
2. 2
   We diagnose on site. We inspect the CGI unit, identify the line and generation, and tell you exactly what’s failed and why. We don’t charge a trip fee inside our home county.
3. 3
   We make the parts call together. For CGI windows still under warranty, we follow the manufacturer’s process so you don’t void coverage by using the wrong hardware. For out-of-warranty units, we quote OEM parts when they’re the right call, and tell you honestly when a quality aftermarket part will do the same job for less.
4. 4
   We do the work with a fixed price. The number we quote is the number you pay. No change orders written on a clipboard at the end of the day.
5. 5
   We test before we leave. Water test, cycle test, alignment check. If it doesn’t operate the way it should, it’s not done.
6. 6
   The Done Right Promise applies. If it’s not done right, we come back and make it right. That’s been the rule since 2011, and it won’t change.

What CGI Impact Windows Costs in Miami

CGI pricing depends on the product line, the size, and whether we’re repairing or replacing. Here’s our real-world experience in Miami’s market:

• IGU replacement on a CGI insulated impact window: $380 to $900, depending on glass size and Low-E coating.
• Balance replacement on Estate single-hung: $140 to $260 per sash, including parts and labor.
• Sliding door roller replacement on Targa or Estate: $220 to $450 per panel, including track cleanup and realignment.
• Crank operator replacement on casement or awning: $160 to $310 per unit.
• Full CGI impact window replacement: $950 to $2,400 per opening, installed, depending on size, series, and whether we’re matching existing trim or cutting new openings.

What moves the price most is glass package, frame size, and whether the job is a straight swap or requires stucco and interior trim work. Call (844) 901-4551 for a free estimate. You’ll get a written, line-item quote before you commit to anything.

Why Miami Homeowners Call Winslow Windows & Doors for CGI Work

Ed Winslow grew up in Hialeah, and he’s been focused on South Florida windows and doors for well over a decade. That means when a homeowner in Shenandoah or Flagami calls about a CGI unit that’s fogging or a Targa slider that grinds, we’ve likely seen that exact failure on that exact product in that exact neighborhood before. We know which CGI series Miami builders put in during which construction boom, and we know how they’ve aged.

We’re also authorized installers for PGT, CWS, ES Windows, and ECO Window Systems, which means if your CGI unit isn’t worth repairing and you want to compare a different brand, we can quote you an honest alternative without running you through a sales presentation. Every technician who shows up is background-checked and in uniform. Every quote is upfront. Ed’s name is on the door, and on every job we do.
