CGI Windows & Doors in Miami, FL | Winslow Windows & Doors
We provide independent CGI window and door service across Miami, from Hialeah to Homestead, without the factory-shop markup. The single biggest factor shaping CGI work here is Miami-Dade’s High Velocity Hurricane Zone (HVHZ) code, which requires a product-specific Notice of Acceptance (NOA) for every opening, a document most contractors never verify until inspection day. That’s where our crew comes in. Call (863) 251-5864 for a free estimate on CGI repair or replacement anywhere in Miami.
Why Miami Residents Choose Us for CGI Service
We’ve been pulling CGI sashes, replacing CGI balances, and rebuilding CGI sills in Miami homes since 2011. That’s over fifteen years of learning exactly how these windows behave when Biscayne Bay salt spray meets July humidity. Ed Winslow grew up in Miami and still lives here. He learned the trade through Miami Dade College’s Building Construction Technology program, then spent years in the field before putting his own name on the truck. His name’s on the business. That means the job doesn’t end when we pull out of your driveway.
We’re an independent CGI service provider, not a manufacturer affiliate. That matters in Miami because we’re free to tell you when a marine-grade aftermarket stainless hinge will outlast the original in salt air, or when the frame itself is shot and replacement is the only honest answer. We carry OEM CGI hardware and glass components where they make sense, and we tell you straight where they don’t. Our techs can identify your exact CGI series, match existing hardware, and confirm whether your current Florida Product Approval numbers still hold up under current code, before you spend a dollar.
Common CGI Windows & Doors Problems We Solve in Miami
- Torn or compressed pile weatherstripping in horizontal rollers. Salt air and rain push past the sash track, corroding the frame and making the window drag. We see this constantly on CGI sales & service calls less than a mile from open water, where marine-grade replacement pile is the only fix that lasts.
- Corroded hinge arms on casement and awning units. The multi-point lock still works, but the hinge rivets are pitted from salt spray and the sash sags, failing to seal against wind-driven rain. We replace those hinges with high-cycle polymer or stainless options before the glass gets compromised.
- Spiral balance failure on older CGI single hungs. Years of humidity and salt exposure leave the aluminum balances so far gone the sash won’t stay raised. In older CBS homes around Little Havana and North Miami, this is one of the most common calls we run.
- Degraded perimeter silicone and missing foam air seals on fixed and picture units. Pre-NOA installations show moisture stains and air leaks during summer storms. We strip the old seal, install proper backer rod and marine-grade silicone, and confirm the NOA on the glass itself.
- Frame pitting at the sill and miter joints. Salt air eats aluminum from the bottom up in Miami. When we catch it early, we can rebuild the sill. When the pitting runs to the weld seams, we’re honest that replacement beats another patch.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Miami-Dade County’s High Velocity Hurricane Zone designation is not a marketing phrase, it’s a legal threshold. Every CGI window or door we supply must carry a product-specific NOA that matches the exact opening size and frame material. No other metro in the U.S. demands this document before inspection. That means a CGI window that passes code in Tampa or Orlando may not pass in Miami, even if it’s the identical product line. The NOA is tied to specific sizes, specific frame materials, and specific glass makeups, and the Miami-Dade Building Department checks every line of it.
For CGI owners, this has a direct consequence. If you bought a home with older CGI Windows already installed, the original NOA paperwork may be missing or the product may have fallen off the current approved list. We pull the exact NOA number for your window model and opening size before we touch the frame, because if that document doesn’t match, the repair won’t clear inspection and your insurance carrier may flag the property. That’s the Miami-specific part no generic window company can help you with.
CGI Models & Products We Service in Miami
We service the full CGI lineup across Miami-Dade, including the CGI Sentinel Series, CGI Estate Collection, CGI Targa Series, and CGI Classic Line. That covers horizontal roller and sliding Impact Windows in Miami, casement and awning units, fixed and picture windows, and single and double hung sashes. For parts, we use OEM CGI hardware and glass whenever it’s available from regional distributors. On many older frames, though, we turn to marine-grade aftermarket stainless components or high-cycle polymer parts that actually hold up longer in Miami’s salt air than the original spec. If the frame’s weld seams or miter joints show pitting, or the original glass no longer carries a valid Miami-Dade NOA for current code, we’ll tell you full replacement beats multiple patch repairs, and we’ll explain exactly why.
CGI Service Pricing in Miami
CGI service pricing in Miami reflects the product line, the failure, and whether replacement glass or hardware must be ordered to match an existing NOA. Typical service calls include a diagnostic trip charge, which we waive entirely if you’re in our home county and we perform the work. Common repairs such as pile weatherstripping replacement on a horizontal roller, spiral balance swaps on a single hung, or hinge arm replacement on a casement run in predictable ranges, but the true cost driver in Miami is hidden frame corrosion or missing NOA paperwork. A free estimate from us includes the diagnostic, the exact part numbers, and the NOA verification for your openings. Call (863) 251-5864 for a written line-item quote before any work begins.

FAQs - CGI Windows & Doors in Miami
Maybe not. The Miami-Dade NOA is tied to your exact window model, opening size, and frame material, and older installations often lack the current paperwork or have fallen off the approved list. We pull the NOA number for your specific unit before any repair, so you’re never left holding a failed inspection. Call (863) 251-5864 and we’ll check your windows.
You’re likely closer to Biscayne Bay or the Atlantic. Within about a mile of open water, salt-laden air corrodes aluminum frames and degrades weatherstripping in under five years, while Kendall’s inland position sees much less airborne salt. The fix is marine-grade replacement parts, which we spec for every coastal Miami CGI repair. Call (863) 251-5864 for a free estimate.
It depends on the frame. If the aluminum is solid and the original glass carried a Miami-Dade NOA that still matches your opening, glass-only replacement is often viable. If the frame shows pitting or the NOA no longer covers the current glass makeup, a full Miami Window Installation is the only honest route. We’ll inspect it and tell you straight.
Yes, but it’s not a standard install. Coral Gables enforces its own historic-preservation overlay on top of HVHZ code, so impact windows must match original divided-lite profiles and may require City Beautiful Board approval. We work that permit path for you and match the exact sightlines. For CGI service in Coral Gables, we handle the full process, from board submission to final inspection.
A properly installed CGI unit with marine-grade seals and stainless hardware should give you fifteen to twenty years in most Miami locations before seals need attention. Homes within a mile of open water will likely need hardware and weatherstripping attention sooner, often in the five-to-eight-year range. We build in that reality with materials that outlast the original spec, not ones that match it. Call (863) 251-5864 for an exact quote on your home’s exposure.
