CGI Windows & Doors Service Nationwide | Winslow Windows & Doors

Why Miami Beach Homeowners Choose CGI Windows & Doors

CGI windows and doors are built for South Florida’s hurricane codes, but even the best impact-rated products eventually need service, especially in Miami Beach’s salt-heavy air. Winslow Windows & Doors is an independent CGI service provider, not an authorized dealer, and we’ve been rebuilding CGI frames, sashes, and hardware across Miami Beach’s high-rise and waterfront homes for over 12 years. Our techs work with original CGI components nearly every day, so we know exactly where these products fail in a barrier-island climate and how to fix them without voiding your warranty. If you have a CGI window or door that isn’t operating right, call Ed Winslow’s team at (863) 656-0462 for a straight answer and a free estimate.

Why Trust Winslow Windows & Doors for Your CGI Windows & Doors?

Ed Winslow grew up in Miami and has spent the better part of three decades learning what the South Florida climate does to a poorly installed window or door. He picked up the fundamentals at Miami Dade College’s Building Construction Technology program, then spent years in the field before putting his own name on a truck. Ed and our crew have worked up and down Miami Beach for years, from older condos near the Faena District to single-family homes just off the boulevard, building a reputation for impact installations done right the first time, no shortcuts.

That background matters when you’re dealing with CGI products. These aren’t generic windows you can swap parts on blindly. CGI impact frames use specific balances, proprietary roller assemblies, and tight-tolerance locking hardware that need a tech who’s actually handled them in the field. Our technicians know the difference between a CGI Estate Collection double hung and a Sentry Series casement without looking at the label. They know which parts must be OEM to preserve the Miami-Dade NOA rating and which components can be safely replaced with quality generics. And every tech arrives background-checked, in uniform, and carrying Ed’s reputation with them. My name is on every job we do. That keeps me honest.

The company itself backs that accountability. We’ve been locally owned since 2011, with a published address and license number. No shell companies, no rotating subcontractor crews. We also stand behind every job with the 36500-Day Done Right Promise: if it’s not done right, we make it right. Period. That’s a century-long standard, and we put it in writing.

Common CGI Windows & Doors Problems We Fix in Miami Beach

Here’s what we actually see on CGI products in Miami Beach, week after week:

• Fogging between glass panes on Estate Collection double hungs. The insulated glass (IG) seal fails, usually after years of thermal cycling and salt exposure. Once moisture gets between the panes, the window loses energy efficiency and looks terrible. We replace the IG unit with Miami-Dade approved impact glass rather than replacing the whole frame when the frame is still sound.
• Roller assemblies seizing on horizontal rollers in beachfront condos. CGI horizontal roller windows are smooth when new, but beach sand works its way into the roller tracks and salt spray corrodes the bearings. The window goes from one-hand operation to two-hand wrestling. We pull the sash, clean the track, and install fresh OEM roller assemblies, which restores the glide.
• Warped sashes on Sentry Series casements. Direct oceanfront sun is relentless. Over a decade or more, the aluminum sashes on CGI Sentry casements can warp enough to break the weather seal, letting air and water in. Sometimes shimming and re-setting the operator helps. Often the sash has to be replaced to restore the impact rating.
• Stripped or rusted locking mechanisms on older CGI fixed windows. Constant humidity plus salt spray eats at handle sets, keepers, and multipoint lock bars. We see this especially on older CGI Classic windows within a few blocks of the ocean. Genuine CGI locking hardware, or a properly matched equivalent, fixes the security issue without compromising the frame.
• Failed spiral balances on CGI Classic single hungs. The original balances in 1980s and 1990s CGI single hungs fatigue over time. Sashes drop when you try to raise them, or they won’t stay up at all. We keep OEM CGI balances in stock for the most common sizes because this is one of the most frequent repairs we make on older Miami Beach buildings.

Each of these failures has a specific cause, and that cause tells us whether it’s a quick repair or a signal that the whole unit is nearing the end of its service life.

CGI Parts & Our Repair-vs-Replace Approach

When a CGI window or door needs parts, we start with genuine CGI components for anything that affects operation, safety, or the Miami-Dade impact certification. That means balances, rollers, locking hardware, and IG units. CGI’s parts are engineered to work with their frames, and putting a knockoff balance in a CGI double hung can create a window that’s harder to operate and wears unevenly.

For non-structural items like weatherstripping, glazing beads, and vinyl gaskets, we offer high-quality generics that match or exceed the original specs. These components don’t affect the impact rating, and the right generic often lasts longer in Miami Beach’s salt air than the OEM material did. We’ll always tell you which parts we’re using and why.

Our repair-vs-replace rule is straightforward: if the frame is sound and the glass is clear, we repair. If the frame is corroded or the sash is warped beyond adjustment, replacement is the only way to maintain Miami-Dade impact certification. We won’t patch a window that’s structurally done just to get the job. And when replacement is needed, we give you a written line-item quote before any work starts, so you know exactly what you’re paying for. Call (863) 656-0462 and we’ll walk you through what your CGI window actually needs, not what’s easiest for us.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis. Our tech arrives, inspects the CGI window or door, and identifies the specific failure. We check the frame for corrosion, test the balances or rollers, and verify the glass condition. On Miami Beach oceanfront units, we also look for hidden salt damage in the weep holes and track channels.
2. 2
   Repair or install. We quote the fix as a written line-item price. If you approve, we complete the work using genuine CGI parts for critical components and quality generics where appropriate. For full frame replacements, we pull the old unit, set the new CGI frame to manufacturer specs, and flash the opening to Miami-Dade code.
3. 3
   Operation and seal test. Every window or door gets operated repeatedly. We check the balance tension, roller glide, lock engagement, and the seal around the sash. If it doesn’t feel right, we adjust it before we leave.
4. 4
   Warranty documentation. We walk you through what was repaired or replaced, what parts were used, and how the warranty applies. The 36500-Day Done Right Promise covers our workmanship. If something isn’t right, you call us and we come back.

We treat every CGI service call as if Ed’s name is going on it, because it is.

CGI Products We Service & Install in Miami Beach

Our techs handle the full CGI residential lineup regularly: the Estate Collection (their premium impact line, including double hungs and casements), the Classic Collection (single hungs, fixed windows, and the older models still common in 1980s and 1990s Miami Beach condos), the Targa Series (horizontal rollers and sliders popular in mid-rise and high-rise buildings), and the Sentry Series (casements and awnings, often specked on direct-oceanfront elevations). We service impact windows, horizontal roller windows, hurricane-rated doors, and perform full frame replacements when the existing unit can’t be saved. CGI parts we keep locally in stock include common balances, roller assemblies, lock hardware, and weatherstripping for the models we see most often on Miami Beach jobs.

We Also Service These Brands

CGI isn’t the only impact brand we work with. Winslow Windows & Doors is an authorized installer for PGT, CWS, ES Windows, and ECO Window Systems, among others. That matters because it means we’re not pushing you toward one brand out of habit. If a PGT frame is a better fit for your opening, or a CWS product matches your existing look more closely, we’ll tell you. Our loyalty is to the person holding the invoice, not to any manufacturer.

FAQs - CGI Windows & Doors Service in Miami Beach

My CGI horizontal roller window is very hard to slide - what’s usually wrong?

In Miami Beach, the usual culprit is sand and salt corrosion in the roller assemblies and tracks. The bearings in the rollers seize up, and the track fills with grit and salt deposits. We pull the sash, clean the track thoroughly, inspect the rollers, and replace them with genuine CGI roller assemblies if they’re worn. If the track itself is corroded, that’s a bigger issue and may point toward frame replacement. Call (863) 656-0462 for a diagnosis, and the trip charge is waived inside our home county.

Can you replace just the glass in my CGI impact window, or do I need a whole new sash?

You can absolutely replace just the glass in most CGI impact windows when the frame and sash are still in good shape. We remove the failed IG unit and install a new Miami-Dade approved impact IG unit that matches the original specifications. This is a common repair for fogged Estate Collection double hungs in Miami Beach. If the sash itself is warped or the frame is corroded, then a full sash or full frame replacement is the honest route. We’ll show you the condition of your frame before quoting anything.

Do CGI windows need special maintenance because of the salt air near the ocean?

Yes, and this is where Miami Beach is harder on windows than almost anywhere else. Salt spray coats the frames, corrodes hardware, and clogs weep holes. We recommend rinsing the exterior of your CGI windows with fresh water every few months if you’re within a few blocks of the ocean, cleaning the tracks, and keeping weep holes clear. The hardware should get a light silicone lubricant annually. If you’re not sure how to do this without damaging the finish, our techs can handle it during a regular service visit. For an exact quote, call (863) 656-0462.

My CGI Estate double hung has condensation between the panes - is that covered under warranty?

Condensation between the panes means the IG seal has failed. Whether it’s covered depends on the age of the window and the terms of the original CGI warranty. Some IG seal warranties run 10 to 20 years, but many older units in Miami Beach are past that window. We can identify the manufacturing date from the glass etching or frame label and tell you where you stand before you spend a dime. If warranty coverage applies, we’ll help you navigate the claim. If not, we’ll quote a replacement IG unit that keeps the window’s Miami-Dade rating intact.

Can you match my existing CGI Classic windows if I’m only replacing a few damaged ones?

Matching older CGI Classic windows is doable in most cases, though it depends on the specific style and the condition of the frames you’re keeping. CGI’s Classic line had several profile styles over the years, and the glass options have evolved. We’ll match the frame color, sightlines, and glass tint as closely as the current product allows. In Miami Beach’s historic districts, where the Historic Preservation Board may require specific sightlines or muntin patterns, we’ll also help you understand what is and isn’t approvable before you commit. Call (863) 656-0462 for a free second opinion on any written estimate you’ve received.
