CGI Windows & Doors in Miami, FL | Winslow Windows & Doors
We provide independent CGI windows and doors service across Miami, from Hialeah to South Miami, and the one thing that makes our CGI work here different is this: we document the Miami-Dade NOA sticker on every unit we touch, because in this city your insurance policy literally references that number. Ed Winslow has been working on CGI product lines since before the post-Andrew retrofit wave, and our crew knows exactly what salt air, CBS walls, and HVHZ code enforcement do to these units over time.

Why Miami Residents Choose Us for CGI Service
Most companies offering Miami Window Installation can sell you a new unit. Fewer can tell you whether the one you already have is worth saving. We’ve worked on CGI’s Miami-Dade NOA product families in Hialeah, Westchester, West Little Havana, and Miami Shores for years, and we’ve learned the details that decide whether an insert holds or fails a wind-mitigation inspection. Ed grew up in the Sunset neighborhood of South Miami and studied building construction technology at Miami Dade College, where he learned to read load paths and understand why windows fail long before they leak. That background matters when a CGI single hung won’t lift, or a slider binds, or a French door threshold lets water in during an afternoon thunderstorm. We’re an independent service provider, not a CGI-authorized dealer. That means we can tell you honestly when a repair makes sense and when full-frame replacement is the smarter spend, without a sales quota breathing down our necks. My name’s on the truck – if the work isn’t right, neither am I.
Common CGI Windows & Doors Problems We Solve in Miami
- Corroded aluminum frames from Biscayne Bay salt air. Salt-laden air off the bay accelerates oxidation on CGI aluminum frames at the weep holes and sill corners. We regularly free up stuck sashes on CGI single and double hung units that are only 8 to 12 years old – a problem you’d rarely see this early in Orlando or Jacksonville. We clean the channels, replace corroded hardware, and reseal the affected areas to slow the next cycle.
- Binding 3-lite sliders on pre-NOA installs. In Hialeah and Westchester, many older CGI horizontal sliders were set into undersized buck framing on CBS walls. Over time the frame sags, rollers flatten, and panels refuse to glide. We replace the roller hardware with OEM parts, adjust the frame alignment, and where needed install proper buck fillers to redistribute the load. This is a repair, not a replacement – most of the time.
- Impact glass seal failure on east-facing elevations. CGI impact laminated glass takes a beating under direct Miami sun, especially on buildings with no overhang protection. The inner seal degrades, and you start seeing hazing or moisture between the panes. Once the seal goes, the unit stops performing as an insulated assembly. We document the damage and recommend whether a sash replacement or full-unit swap is the right call.
- Leaking CGI French door thresholds. Older CGI entry and French door units came with compression gaskets that lose their memory in Miami’s heat. The first heavy wind-driven rain finds the gap, and water ends up on your floor. We replace the threshold sweeps and corner pad kits, and when the threshold itself has corroded, we rebuild it with corrosion-resistant materials that hold up better near the coast.
- Jalousie-to-CGI rough opening mismatches. A huge share of Miami homes built between the 1950s and early 1980s still have original jalousie windows. Those openings don’t match modern CGI impact unit dimensions. We custom-build buck framing for CBS walls so the new CGI unit seats correctly, seals tight, and passes inspection the first time. Skipping this step is why so many Miami retrofit jobs fail.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Here’s something you won’t hear from an out-of-town estimator: in Miami, your CGI window’s Miami-Dade NOA number shows up on your home insurance policy declaration page. Nowhere else in Florida – except neighboring Broward County – does that happen, because Miami sits entirely within the High Velocity Hurricane Zone. What that means for CGI owners is practical. After every repair or replacement we perform, we photograph and document the approval sticker on the unit. That photo trail is what you’ll need when your carrier audits your policy, or when a wind-mitigation inspector asks for proof of compliant opening protection. We’ve had customers in West Little Havana and Hialeah come to us after their carrier threatened non-renewal because they couldn’t produce that documentation after another contractor’s work. We don’t let that happen. Miami’s sustained Category 4-5 wind-load requirements, combined with flat sea-level topography that lets surge push harder against first-floor openings, mean your CGI units are doing structural work, not just keeping rain out. The paperwork proving they’re compliant matters as much as the hardware itself.
CGI Models & Products We Service in Miami
We service the full span of CGI product families found in Miami homes, including the Estate Collection impact casement and picture windows, Classic Fixed and Single/Double Hung impact lines, 3-lite sliders with heavy-duty roller hardware, and French/impact hinged door units. Parts strategy matters. We stock OEM CGI replacement hardware – rollers, balances, locking points, gaskets, and pivot bars – because mixing aftermarket components on NOA-approved impact units can void the product approval. That void is exactly what triggers insurance inspection failures. For CGI lines that are out of production, we use only grade-compatible, corrosion-resistant aftermarket parts, and we’re upfront with you when a 15-plus-year-old Miami unit has reached the point where full-frame replacement beats another round of repairs. See our CGI sales & service overview for more detail on how we approach the brand.
CGI Service Pricing in Miami
CGI service pricing in Miami depends on what’s actually wrong. A roller replacement on a 3-lite slider runs a different number than a full-frame jalousie conversion with custom buck framing on a CBS wall. Generally, our repair work starts around $200 for simple hardware swaps (remember, $40 off any repair over $200), while sash replacements, frame rebuilds, and full conversions scale up based on materials and hours. We quote line-item pricing before any work starts, so you know what you’re paying and why. No change orders hidden in the fine print. If you already have a written estimate from someone else, bring it to us – free second opinions are a standing offer, and there’s no trip charge inside our home county. Call (850) 930-1813 for an exact quote. Estimates are free.

FAQs – CGI Windows & Doors in Miami
Yes, provided the repair work maintains the unit’s original NOA compliance status. That means OEM or grade-compatible parts and proper installation methods on the existing approved assembly. We photograph and document the approval sticker after every repair, so your carrier has the proof it needs during renewal or audit. Call (850) 930-1813 if you’re preparing for an inspection and want us to verify your openings.
In most cases, yes. On pre-NOA Hialeah and Westchester installs, the original buck framing was often undersized for the weight of a 3-lite CGI unit. The frame sags over time, rollers flatten, and the panels bind. We replace the roller hardware, realign the frame, and install proper buck fillers to carry the load. Whole-frame replacement is rarely necessary unless the aluminum itself has corroded through. Call (850) 930-1813 for a free assessment.
Almost always a gasket problem, not a glass problem. The original compression gaskets on older CGI French and entry door thresholds lose their memory after years of Miami heat, and the first wind-driven rain finds the gap. We replace the threshold sweeps and corner pad kits, and rebuild corroded thresholds when needed. The fix is straightforward. Call (850) 930-1813 and we’ll confirm what’s leaking before recommending any work.
Yes, and we do it regularly. Jalousie windows were built to a rough-opening standard that no longer exists, so modern CGI impact units don’t drop in. We custom-build buck framing so our Impact Windows in Miami bridge the gap inside the existing CBS opening. The wall stays intact, the CGI unit seats correctly, and the installation passes Miami-Dade inspection. Call (850) 930-1813 to schedule a measurement and free estimate.
Every 2 to 3 years. Salt-laden air off Biscayne Bay and the Atlantic corrodes aluminum frames and degrades glazing seals faster than inland Miami neighborhoods or anywhere north of Broward. A quick service visit lets us catch oxidation at weep holes and sill corners before sashes freeze up. For homes within a mile of the water, we recommend an annual check. Call (850) 930-1813 to schedule.
