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

CGI builds some of the toughest Impact Windows services-rated windows and doors on the market. But any window installed in South Florida takes a beating, and knowing how a CGI unit fails is what separates a real service call from a guess. Our technicians have worked on CGI products across Mangonia Park for over a decade. We know the Sentinel Series casement hinge geometry, the Estate Collection roller track wear points, and the Targa Series frame tolerances well enough to diagnose a problem over the phone half the time.

Ed Winslow grew up here in Mangonia Park, not far from the old Town Hall, and still lives close enough to run into customers at the hardware store on a Saturday morning. He learned construction technology at Palm Beach State College, then spent years installing and replacing windows and doors across Palm Beach County before putting his own name on the truck. That background matters when we’re working on CGI products: we treat every repair as if it’s going into our own house, because in a town this small, it often is.

When we service CGI windows and doors, we use genuine CGI OEM parts whenever available. Locks, balances, hinges, and weatherstripping all have exact specifications. Aftermarket substitutes often fail Miami-Dade code verification, which means your CGI product stops performing like a CGI product. We won’t do that to you.

As an independent CGI service provider, we’re not bound by manufacturer service restrictions. We can tell you plainly when a repair is worth the money and when a full-frame replacement makes more sense. That’s the kind of straight answer CGI owners in Mangonia Park deserve.

Key takeaways:

• Independent, factory-trained CGI service provider serving Mangonia Park since 2011
• Genuine CGI OEM parts used whenever available
• Locally owned by Ed Winslow, who grew up in Mangonia Park
• Live person answers every call, 24/7
• Backed by the Done Right Promise: if it’s not done right, we make it right

Common CGI Windows & Doors Problems We Fix in Mangonia Park

CGI products are engineered for hurricane zones, but CGI Windows & Doors in South Palm Beach, FL and Mangonia Park’s specific climate creates predictable failure patterns. Here’s what we see most often:

• Sentinel Series horizontal roller windows: track wear from sand and salt. Mangonia Park sits roughly five miles inland, but salt-laden air still carries. The lower tracks on CGI Sentinel horizontal roller windows accumulate fine sand and salt that score the aluminum. Once the track is grooved, the sash rollers stop rolling and start sliding, which makes the window sticky or impossible to open. We replace the OEM rollers, clean and repair the track, and install fresh weatherstripping.
• Sentinel Series picture windows: weep hole blockage. CGI Sentinel picture windows are fixed units with weep holes that drain accumulated water from the frame channel. In Mangonia Park, wind-blown debris and insects clog these holes. Water backs up, finds the interior seal, and stains drywall. Clearing the weep holes and replacing deteriorated seals usually solves it. This is a quick fix, but it needs to happen before the water reaches your interior framing.
• Estate Collection insulated glass: corner seal shrinkage and fogging. The Estate Collection uses vinyl frames with insulated glass units. Heat and humidity cycles in Mangonia Park stress the IG corner seals. When they shrink or separate, moisture gets between the panes and you see fogging or condensation you can’t wipe away. This means the IG unit has failed. We measure the exact sash dimensions and order a replacement IG that matches the original CGI spec.
• Sentinel Series casement windows: bent or corroded stainless steel hinges. High wind cycles and coastal air do a number on casement hinges. We’ve opened Sentinel casements in Mangonia Park where the stainless steel hinges had visible corrosion or micro-bends from repeated wind buffeting. A bent hinge changes the sash alignment, which breaks the weather seal and makes the crank bind. Hinge replacement with genuine CGI hardware restores the window.
• Older CGI 610 Series vinyl windows: non-impact glass in a hurricane zone. Not every CGI product is impact-rated. The 610 Series is a non-impact vinyl line. If your Mangonia Park home still has 610 Series windows from the 1990s or early 2000s, they’re not close to meeting current Palm Beach County wind-borne debris standards. We’ll give you an honest assessment of whether upgrading to Sentinel impact glass makes sense for your openings.

CGI Parts & Our Repair-vs-Replace Approach

When a CGI window or door fails in Mangonia Park, the first question is whether to repair or replace. Our answer depends on three things: the age of the unit, the condition of the frame, and whether the glass is impact-rated.

For CGI products still in production, like Sentinel, Estate, and Targa lines, we use genuine OEM parts. Locks, balances, hinges, weatherstripping, and rollers all have exact tolerances. Aftermarket parts might fit, but they won’t pass Miami-Dade code verification, and that invalidates the reason you bought CGI in the first place. For out-of-production CGI hardware, we source certified equivalents only when they match OEM dimensions and pressure ratings. If we can’t get a component that meets the original spec, we’ll tell you, and we’ll recommend replacement.

We recommend replacement over repair when the frame is compromised, when the sash is non-impact and you’re in the wind-borne debris zone, or when the cost of repairing multiple components exceeds roughly 60 percent of a new unit’s installed price. Around Mangonia Park, where so much of the building stock is older commercial and industrial construction, we also see aluminum storefront sections where the frame itself has corroded at the base. That’s a replacement situation, not a patch job.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis. We listen, then look. When we arrive at your Mangonia Park property, we inspect the full window or door: frame, glass, hardware, and the opening itself. For CGI units, we check the Miami-Dade label, the installation anchors, and the seal condition. We explain what failed and why in plain language.
2. 2
   Repair or replacement plan. We price the repair with genuine CGI or certified-equivalent parts, and we price a replacement side by side when it’s warranted. You decide. No pressure, no inflated numbers. Our quote is line-item and written.
3. 3
   Service or installation. For repairs, we replace the failed component, clean and lubricate the track or hinge assembly, and adjust alignment. For full-frame CGI replacements in Mangonia Park, we pull the old window, inspect and repair the rough opening, install per Florida Building Code impact standards, and flash and seal the perimeter.
4. 4
   Testing. We cycle every operable window and door multiple times. For impact units, we verify the interlock engagement and the seal compression. We open and close every casement, roller, and single hung under our own scrutiny.
5. 5
   Warranty and follow-up. Every CGI service and installation is covered by the Done Right Promise. If it’s not done right, we make it right. My name is on the business. That means your windows are my responsibility long after we’ve packed up the truck.
