CGI Windows & Doors in Miami, FL

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

We provide independent CGI windows and doors service across Miami, from Brickell high-rises to 1950s CBS homes in Westchester. The one thing that makes our CGI work here different: Miami-Dade is the only county in the country where every replacement window or door must carry a county-issued Notice of Acceptance (NOA), not just a Florida Product Approval. So we verify NOA compliance on every CGI job before we touch a frame. Need CGI repairs, parts, or full replacement? Call (863) 862-5435 for a free estimate.

Why Miami Residents Choose Us for CGI Service

Ed Winslow grew up in Kendall and learned the trade through Miami Dade College’s construction technology program, so he’s seen firsthand what Miami’s salt air and humidity do to window hardware over twenty years. Our CGI sales & service work is built on that local experience. We’re an authorized installer for CGI and seven other premium brands, which means our techs know CGI product lines the way a mechanic knows a particular engine. When your Classic 2400 won’t stay up or your 9600 Series roller is jammed with corrosion, we know whether it’s a fifteen-minute part swap or a full-frame conversation. Ed’s name is on the door, and his standard is simple: if it’s not done right, we make it right.

Common CGI Windows & Doors Problems We Solve in Miami

• Salt-air pitting on CGI aluminum frames. Within a mile of Biscayne Bay or the Atlantic, the marine layer works on raw aluminum like sandpaper. We regularly see CGI frames with white oxidation blooming along the bottom track, which binds the sash until it won’t lift without a fight. In Westchester and Shenandoah, homes built in the 60s and 70s are the worst hit because their original CGI aluminum frames predate current marine-grade anodizing.
• Failed interlocking meeting rails on Classic 2400 single hungs. Miami’s near-daily summer thunderstorms drive rain sideways into window tracks. On CGI Classic 2400 units, the interlocking meeting rails eventually wear down, and water starts seeping through the center seam during heavy downpours. We see this most often on east-facing elevations where wind-driven rain hits dead-on.
• Deteriorating wool pile weatherstripping on 9600 Series horizontal rollers. The wool pile along the sash edges hardens and crumbles after years of UV exposure and humidity cycles. You’ll notice humid air leaking in, more insects around the window tracks, and a whistling sound when the wind picks up. Replacing the weatherstripping with fresh, marine-spec material restores the seal.
• Stripped or corroded locking hardware on CGI hinged doors. In high-rise condos from Brickell through Edgewater, salt fog accumulates on balcony doors and eats through the internal components of CGI door locks. A door that won’t latch properly is a security problem and, during a storm, a structural one. We replace corroded locking hardware with stainless steel components that hold up in coastal air.
• Non-NOA CGI models failing inspection. We’ve corrected more than a few installations where a previous contractor from Broward or Palm Beach installed a CGI model that carries a Florida Product Approval but no Miami-Dade NOA. The product might be fine in Fort Lauderdale, but Miami’s building department won’t pass it. We verify NOA documentation before replacing any unit in the county.

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

Here’s the fact that matters most for CGI owners in Miami: this is the only county in the entire United States where every replacement window or door must carry a Notice of Acceptance issued by Miami-Dade County itself. Not a statewide Florida Product Approval. Not a generic “impact-rated” label. The county’s own product control division reviews and approves each specific model for use in the High-Velocity Hurricane Zone, and building inspectors check for that NOA sticker on the frame. A CGI window installed in Broward without an NOA might pass inspection up there but fail down here, and if your windstorm carrier does a post-installation audit, that non-NOA unit can trigger a non-renewal. This is why our Miami service area work always starts with NOA verification. We check the product’s county approval status before we order parts or recommend replacing anything, so you’re not paying for a repair on a unit that can’t pass inspection anyway.

CGI Models & Products We Service in Miami

Our techs work on the full CGI lineup common across Miami homes and condos, including the Classic 2400 Series single hungs, the Estate Collection casements and picture windows, the 9600 Series horizontal rollers, and 4-1/4″ frame commercial storefront doors. When a CGI product is still under its Miami-Dade NOA and the frame is structurally sound, we use genuine CGI replacement parts: balances, rollers, locks, and weatherstripping. For CGI lines that have gone out of production, we source marine-grade aftermarket hardware that meets HVHZ corrosion standards, so the repair holds up in coastal conditions. We stock the most common CGI parts locally for fast Miami turnaround, which means less waiting on backorders when your window is already leaking.

FAQs - CGI Windows & Doors in Miami

Do CGI windows need a Miami-Dade NOA even if they already have a Florida Product Approval?
Yes. A Florida Product Approval is not enough in Miami-Dade County. The county requires its own Notice of Acceptance for every window and door product installed in the HVHZ. If your CGI unit only has a statewide approval, it won’t pass inspection here, and your windstorm insurance may not recognize it. We verify NOA status on every job before recommending repair or replacement. Call (863) 862-5435 and we’ll check your specific CGI model.

Can you repair the salt-air corrosion on my existing CGI aluminum frames, or do I need full replacement?
It depends on how deep the corrosion has gone. Surface pitting and oxidation can often be cleaned and treated with marine-grade corrosion inhibitor, then resealed. But if the aluminum has been eaten through the anodized layer to the point where the frame is pitted, weakened, or the sash binds permanently, a full replacement is usually the honest answer. We’ll show you exactly what we’re seeing and give you a repair-versus-replace number before you decide.

What is the difference between repair and replace for my CGI Classic 2400 single hung that won’t stay up?
If the problem is a worn balance or a loosened screw, that’s a repair: typically under $300. If the meeting rails are corroded shut or the frame has salt-air pitting from years near the bay, the repair cost can approach 60 to 70 percent of a new NOA-approved unit, and replacement makes more sense. We’ll give you a straight answer on which route saves you money long-term. Call (863) 862-5435 for an on-site look at your specific window.

Do you handle CGI window replacement in high-rise condos where the HOA requires uniform appearance?
Yes, we work with condo boards and property managers throughout Brickell, Edgewater, and Sunny Isles on CGI replacements that match the building’s existing aesthetic. That means matching frame color, glass tint, and operable style to the HOA’s architectural guidelines. We provide documentation and samples for board approval before any unit is ordered, and we coordinate installation around building access schedules and high-elevation logistics.

Will replacing my old jalousie windows with Impact Windows in Miami really lower my Citizens insurance premium?
In most cases, yes. Citizens Insurance offers windstorm premium discounts of 20 to 45 percent for verified impact-rated openings, and jalousie windows carry zero impact resistance and often trigger non-renewal notices outright. Once we complete the CGI replacement, we provide the NOA documentation your agent needs to update the policy. The discount varies by policy and home specifics, but for older Miami homes with original jalousies, the insurance savings usually pay for a meaningful portion of the installation cost. Call (863) 862-5435 and we’ll walk you through what to expect from your carrier.
