CGI Windows & Doors in Tampa, FL

CGI Windows & Doors in Tampa, FL | Winslow Windows & Doors

We’re Winslow Windows & Doors, and we provide independent CGI window and door service and Tampa Window Installation throughout Tampa. If you own a home here, you likely already know the headache: insurance carriers are non-renewing policies over non-impact glazing, and CGI is one of the few brands that consistently earns full wind-mitigation credit on the OIR-B1-1802 form. The difference with us is we’ve spent years working on CGI systems inside Tampa’s concrete-block ranch homes, so we know what actually fails here and what to do about it. Call (386) 559-6999 for a straight answer and a free estimate.

Why Tampa Residents Choose Us for CGI Service

We’ve been installing and servicing CGI sales & service across Tampa since 2011, and Ed Winslow’s name is on the door – literally. Ed grew up in Miami and learned the trade at Miami Lakes Educational Center before spending nearly two decades measuring, installing, and standing behind windows and doors across the Tampa Bay area. That matters because CGI windows installed wrong are worse than no impact windows at all. A code inspector in Hillsborough County will pull the FL# off every unit and cross-check it against the permit. If the anchoring is off, if the buck framing doesn’t match the masonry opening, if the flashing isn’t right – you fail. We’ve passed hundreds of those inspections because we treat every CGI opening in Tampa like it’s going to face a named storm next season. That’s not a sales pitch. It’s how we work.

Common CGI Windows & Doors Problems We Solve in Tampa

Here’s what we actually see in the field, week after week, across Tampa’s neighborhoods:

• Fogged impact laminated glass from salt-water intrusion. Homes within two miles of Tampa Bay – especially in South Tampa and Davis Islands – get a steady diet of salt air. It seeps into the aluminum frame weep holes, attacks the edge seal on the laminated glass, and you end up with a permanent haze between panes. The impact rating still holds, but you can’t see out of the window. We replace the sash with OEM glass, not a cheap reglaze.
• Corroded frame corners at the sill on older CGI Sentinel units. Hurricane-driven rain pools at the bottom corners of the frame. On units with original mill finish, that moisture sits and eats the aluminum from the inside out. By the time you see pitting or white powder, the corner is compromised. If it’s corroded through, we tell you straight: replace the window. A patched impact frame is a false sense of security in a wind-borne debris region.
• Jalousie panes in Florida room additions that were never CGI-rated. Tampa has thousands of post-original Florida room additions with jalousie glass. The main house may have impact windows, but those jalousies shatter inward under wind-borne debris. When we convert those rooms to code-compliant enclosures, we demo the jalousie frames entirely and reframe for CGI impact units.
• Roller assemblies on CGI horizontal sliders binding from salt corrosion. After years of salt air, the rollers seize up. The sash gets nearly impossible to move – which is a real problem when you need egress in a hurry. We replace the roller assemblies and clean the track, and if the frame itself is too far gone, we say so.
• Bent or missing corner keys on CGI casement frames. Repeated racking during high-wind events bends the corner keys. The sash sags, the locking points miss the strike plate, and you can see daylight at the top corner. That’s not a warranty issue on its own – it’s a structural problem from wind loading, and it needs a proper fix, not a shim.

CGI Service in Tampa: What Local Conditions Mean for Your Equipment

Here’s something you won’t read on a generic CGI page, because it’s specific to Tampa housing stock. Most of Tampa’s homes from the 1950s through the 70s are concrete block construction – CBS ranch homes concentrated in South Tampa, Seminole Heights, Carrollwood, and Temple Terrace. The window openings are cast directly into the masonry. That means any CGI replacement requires tapcon anchoring into the block and custom buck framing to create a solid nailing surface for the new window. In wood-frame markets like St. Petersburg, that skill set is almost never needed – you just nail into studs. Here, if the contractor doesn’t know how to frame and anchor into CBS, the window flexes under wind load, the seal breaks, the frame leaks, and the wind-mitigation inspection fails on the spot. We’ve built our Tampa reputation on getting this right. Our tech was called to a 1962 CBS ranch in Seminole Heights after the homeowner’s insurance carrier flagged non-impact aluminum casement windows on the OIR-B1-1802 form. We removed the original single-pane casements, tapcon-anchored custom pressure-treated bucks into the block openings, and installed CGI Sentinel Series impact casements with stainless steel hinges rated for salt air. The county inspector cross-checked the FL# on each unit against the permit application, and the homeowner’s wind-mitigation report now shows full credit, cutting his premium by over $2,400 a year. That’s what we mean when we say the install is the difference.

CGI Models & Products We Service in Tampa

We service the full CGI lineup you’re most likely to have in a Tampa home: the Sentinel Series, the Estate Collection, the Commercial Series, and the Classic Series. If your CGI windows are still under structural warranty, we source OEM replacement sashes, balances, and weatherstripping so the factory spec stays intact. For discontinued or out-of-warranty units, we use mill-certified aftermarket components that match the original profile exactly – no universal-fit hardware, no adapting something that’s close enough. We also handle full frame replacements, impact-resistant windows, Impact Windows in Tampa, hurricane impact windows, and horizontal roller and sliding impact windows. And to be clear about who we are: we’re an independent service provider, not a CGI-authorized dealer. We recommend repairs or replacements based on what the home actually needs, never on a factory quota. If a repair makes sense, we’ll tell you. If it doesn’t, we’ll tell you that too.

FAQs - CGI Windows & Doors in Tampa

Will replacing my non-impact jalousie windows in a Tampa Florida room with CGI impact windows actually lower my insurance premium?
Yes, in most cases it will. Once the new CGI windows are installed and the permit is closed, your wind-mitigation inspector updates the OIR-B1-1802 form to show impact-rated glazing on that opening. Many Tampa homeowners see premium reductions of $1,500 to $2,400 or more per year after converting jalousie Florida rooms to CGI impact units, depending on the rest of the home’s mitigation features. Call (386) 559-6999 and we’ll walk you through what your specific house would qualify for.

Do I need a permit and product approval number just to replace one CGI window in Tampa, or only for whole-house jobs?
Yes, every replacement – even a single window – requires a permit in Hillsborough County, and the installed unit must carry a Florida Product Approval (FL#) that matches the permit application. The inspector checks this on site. We pull the permit, list the correct FL#s for every unit, and close the permit after inspection.

Why is the aluminum frame on my CGI slider corroding near the bottom corners even though the window is only five years old?
In Tampa, especially within a couple miles of the Bay, salt air attacks aluminum frames at the sill where hurricane-driven rain pools. The weep holes are supposed to drain that water, but salt residue builds up over time and accelerates galvanic corrosion. Five years is faster than we’d like, but it happens. We can assess whether the frame is salvageable with cleaning and sealant or whether you need a sash or full frame replacement. Call us at (386) 559-6999 and we’ll give you a straight answer.

Can you match new CGI impact windows to the existing non-impact CGI windows on my 1990s Carrollwood home, or will the whole elevation look mismatched?
CGI’s current Sentinel and Estate profiles are close to their older frames, but not exact. If only part of the elevation needs replacement, we talk through how the new units will read from the street. In many cases, the difference is subtle enough that most homeowners are fine with it. If it will look mismatched, we’ll tell you before you spend a dollar, and we’ll quote you for a full elevation match so you’re making an informed call.

My CGI casement window locks but the sash still rattles in high wind, and I can see daylight at the top corner. Is this a warranty issue or an installation problem?
Usually neither. What you’re describing is typically a bent or missing corner key from repeated racking during high-wind events, which happens to casement windows in Tampa regardless of who installed them. The sash sags, the locking points miss the strike plate, and air gets through. It’s repairable – we replace the corner key, realign the sash, and adjust the locking points. If the frame itself has been racked too far, we’ll recommend replacement. Call (386) 559-6999 for a free estimate on either path.
