CGI Windows & Doors in South Miami, FL | Winslow Windows & Doors
We provide independent CGI window and door service across South Miami - repair, retrofit, and full replacement on every model line from Sentry to Estate. What makes our CGI work different here comes down to one thing: South Miami sits inside Miami-Dade’s High Velocity Hurricane Zone, and we’ve spent over a decade fixing and replacing CGI units on the 1950s-1970s concrete block homes that dominate this city. Call (850) 930-1813 for a free estimate from a crew that actually knows CGI hardware. We’re not an authorized CGI dealer - we’re CGI sales & service specialists who work for you, not the manufacturer.
Why South Miami Residents Choose Us for CGI Service
Ed Winslow founded this company in 2011, and he grew up in South Miami’s Sunset neighborhood, a few blocks from Dante Fascell Park. He learned construction the right way - building construction technology at Miami Dade College - and spent nearly two decades figuring out why windows fail long before they leak. So when we open up a CGI Sentry Series frame and find corrosion at the sill screws, it’s not a surprise to us. We see it every week on homes within two miles of the coast. That familiarity means faster diagnosis, the right parts on the first truck roll, and repair work that respects the NOA requirements South Miami’s building department enforces.
Every technician who knocks on your door is background-checked and uniformed. You’ll know exactly who we are before the truck even parks. And when you call, a live person answers - 24 hours a day, every day. No call center, no voicemail loop. Our published address and license number sit on every estimate we write. Ed’s name is on the door - and on every job we do.
Common CGI Windows & Doors Problems We Solve in South Miami
- Sentry Series sill corrosion. In South Miami’s salt-laden humidity, older aluminum Sentry frames develop white powdery corrosion at the sill screws and weep-hole baffles. This shows up fastest on homes within two miles of the coast. We remove the corrosion, replace the hardware, and reseal the openings before the frame gets compromised.
- Estate casement operator binding. Those stainless hinges on Estate units are built well, but the original lithium grease hardens after 10-12 years. Owners force the crank during the rainy season and strip the gear teeth. We replace the operator with OEM CGI parts and lubricate the hinge points properly - before you break the crank off entirely.
- Tropic sliding door roller flattening. Repeated storm-pressure cycles push down on those rollers and they slowly flatten. The door starts dragging, then the interlock hook misaligns. A South Miami inspector will flag that as a direct HVHZ failure on a 4-point inspection. We replace the rollers and realign the interlock to pass code.
- Cracked glazing beads on picture windows. Intense UV exposure along SW 58th Avenue dries out the rubber glazing bead on CGI picture windows until it cracks. Wind-driven rain follows that crack right into the frame. We source OEM beads and reseal the glass properly - not with whatever caulk is on the shelf.
- Original jalousie windows needing full-unit swap. South Miami’s post-war bungalows and CBS ranch homes are packed with original jalousie windows. They cannot be retrofitted to meet impact standards - any permitted replacement is automatically a full-unit swap to a modern CGI impact window or door. We handle the entire swap to NOA compliance.
CGI Service in South Miami: What Local Conditions Mean for Your Equipment
South Miami’s building department is stricter than most neighboring jurisdictions in one specific way: the Miami-Dade NOA product approval number must be printed on every permit for window and door replacement. If your CGI unit’s original NOA label is faded, painted over, or missing, the inspection is automatically failed - even if the window is structurally perfect. Neighboring unincorporated Miami-Dade sometimes accepts manufacturer letters of equivalency; South Miami does not. So when we service CGI windows on homes near SW 57th Court or the historic core off SW 58th Avenue, we always verify the NOA label before work begins. If it’s gone, we document the replacement path so your permit doesn’t stall at the inspection stage. That one check saves South Miami homeowners weeks of back-and-forth with the building department. Our field crews have rebuilt, retrofitted, and serviced CGI windows and doors across South Miami’s CBS housing stock for over a decade, and we know exactly where these inspection snags happen.
On a 1958 CBS ranch off SW 57th Court, our crew pulled six original jalousie windows and found the rough openings had settled unevenly - typical for post-war concrete block in South Miami. We squared each opening with full-frame CGI Sentry Series single-hung Impact Windows in South Miami, and when the homeowner’s 4-point inspection came back, the inspector flagged only the front entry door. We replaced it the same week with a CGI Tropic Series hurricane-rated door to complete the NOA set.
CGI Models & Products We Service in South Miami
We work on the full CGI lineup: Estate Collection, Sentry Series, Tropic Series, and 980 Series windows and doors, including the older out-of-production Sentry frames still found on South Miami homes. Our approach to parts is simple - we use OEM CGI hardware whenever replacement is needed. Rollers, balances, crank operators, weatherstripping, glazing beads: aftermarket parts rarely match the NOA-tested interlock dimensions, and a mismatched part can fail your inspection. For out-of-production Sentry frames, we recommend full-sash replacement with current CGI Estate sashes rather than retrofitting mismatched glazing beads. We keep common CGI service hardware stocked locally to keep turnaround fast for South Miami customers.
We handle impact-resistant windows, hurricane impact windows, full frame replacement, and insert window replacement. If you’re converting from jalousie to impact, the service area cover we do across South Miami service area includes permit-ready documentation with the NOA product number on file.
CGI Service Pricing in South Miami
CGI service pricing depends on the repair: a roller replacement on a Tropic sliding door runs less than a full sash swap on an Estate casement. A full-frame CGI impact window replacement in South Miami starts from the window cost plus South Miami Window Installation, and you’ll see the labor and materials laid out separately on your estimate. Every quote includes a written line-item breakdown - materials, hardware, and labor - so you know exactly what you’re paying for. We offer a permanent $40 discount on any repair over $200, free second opinions on written estimates, and a 10% discount for seniors and veterans. No trip charge inside our home county. Call (850) 930-1813 for your free estimate - we’ll measure, inspect the NOA label, and give you a straight answer.

FAQs - CGI Windows & Doors in South Miami
My CGI window has a Miami-Dade NOA sticker but it’s faded. Will it pass a South Miami inspection?
No. South Miami’s building department requires the NOA product approval number to be legible on every permit submission. If the sticker is faded beyond readability, the inspection is automatically failed. We document replacement options and can help you source a compliant replacement before you file the permit. Call (850) 930-1813 and we’ll verify your label during the estimate visit.
Can you convert my original jalousie windows to CGI impact windows without reframing the opening?
Yes, in most cases. Jalousie windows cannot be retrofitted to meet impact standards, so the conversion is a full-unit swap. We remove the jalousie frame, square the opening, and install a full-frame CGI Sentry or Estate impact window with the required NOA documentation. The rough opening usually needs only minor adjustment on South Miami’s CBS homes. Call (850) 930-1813 to schedule a measurement.
Why does my CGI sliding door fail its 4-point inspection even though the glass is intact?
The glass is only one part of the HVHZ standard. Inspectors check the interlock hook, roller condition, and frame fastening. If the rollers have flattened and the interlock is misaligned, or if the original NOA label is missing, the door fails - regardless of the glass. We replace rollers, realign interlocks, and confirm NOA compliance before you schedule the inspection. Call (850) 930-1813 for a free check.
Are CGI windows more corrosion-resistant than other brands in South Miami’s humidity?
CGI’s aluminum frames hold up better than many competitors, but they’re not immune to South Miami’s salt-laden air. We see white powdery corrosion on older Sentry frames within two miles of the coast, especially at the sill screws and weep-hole baffles. Newer CGI models use improved coatings, but regular inspection of the sills and weep holes will extend the frame life. Call (850) 930-1813 if you’re seeing white residue on your frames.
Do CGI windows keep their energy efficiency in South Miami’s heat, or do the seals fail quickly?
CGI’s seals are built for high UV and humidity, but South Miami’s intensity will eventually crack any rubber glazing bead. We see seal failures on picture windows along SW 58th Avenue after roughly a decade. The glass itself remains energy-efficient; it’s the perimeter seal that needs replacing. We stock OEM beads locally for fast turnaround. Call (850) 930-1813 to have your seals inspected.
