CGI Windows & Doors in Miami, FL | Winslow Windows & Doors
We’re Winslow Windows & Doors, an independent CGI service provider working throughout Miami. Most of our service calls here start the same way: a homeowner discovers their existing CGI units no longer meet Miami-Dade’s NOA requirements, or salt air has finally gotten to the frames. We fix both problems, and we’ve been doing it since 2011. Call (904) 478-8983 for a free estimate on any CGI repair or replacement in Miami.
Why Miami Residents Choose Us for CGI Service
The honest answer is that we’ve spent years servicing CGI products across Miami-Dade’s High-Velocity Hurricane Zone, and that experience matters more here than anywhere else in Florida. Ed Winslow grew up in Coconut Grove and studied building construction technology at Miami Dade College, so he knows what salt-laden air off Biscayne Bay does to an aluminum frame by year eight. We’re an independent shop, which means we’re not pushing you toward whatever the manufacturer wants to sell this quarter. We’re looking at what actually keeps your CGI windows and doors performing in Miami, from frame rebuilds to hardware replacement, using genuine CGI parts where structural integrity depends on them. And yes, a live person answers our phone 24/7. No voicemail loops.
Common CGI Windows & Doors Problems We Solve in Miami
Here’s what we see most often across Miami, tied to the specific conditions that cause them:
- Aluminum frame pitting and white corrosion along bottom rails. Older Estate Collection units in Coconut Grove and Brickell sit close enough to Biscayne Bay that salt air eats standard aluminum finishes. The pitting isn’t cosmetic. Left alone, it compromises the frame’s load path during a storm. We strip, treat, and seal these frames or rebuild them with marine-grade components when the damage runs deep.
- Failed glazing seals on impact glass units. After 10 to 14 years of Miami’s combined UV and humidity, the seal between panes breaks down. You’ll see fogging between the glass, and that’s more than an eyesore. A failed seal means the impact rating on that pane is no longer what the NOA specified. We replace the glass unit and verify the new seal meets current Miami-Dade standards for your specific model.
- Rusted and seized stainless hinges plus roller assemblies on sliding glass doors. East-facing high-rise condos get marine moisture driven into the track channels. We see this constantly in Brickell and Edgewater. The door grinds, sticks, or won’t lock properly. We replace the rollers and hinges with marine-grade options that resist what Miami throws at them.
- Worn weatherstripping and deteriorated sill flashing. Estate Collection windows installed before current NOA flashing-tape standards were adopted tend to leak during summer thunderstorms. Water intrusion starts slow, but it rots the rough opening over time. We replace the flashing and weatherstripping to current code.
- Multi-point lock failures on Estate French doors. The constant humidity cycle causes internal components to corrode and bind. This is a genuine CGI structural component, so we use OEM replacement hardware whenever it’s available. Aftermarket pieces fail Miami-Dade NOA inspection or compromise the unit’s impact rating.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Miami-Dade County requires every CGI window and door to carry a Miami-Dade Notice of Acceptance, what locals just call an NOA. This is more stringent than Florida’s statewide building code. A unit that passes inspection in Orlando or Tampa is still illegal to install in Miami without a valid NOA number. Inspectors will fail the job, and frankly, your insurance carrier will take note. Half of our initial service call in Miami is simply verifying the original NOA documentation on existing CGI installations. If you bought a house with CGI windows already in place, and no one can find the NOA paperwork, you need to address that before any sale, re-roof, or major remodel. We pull the records, verify the model numbers against Miami-Dade’s product control database, and if the NOA is missing or the units were never approved, we walk you through the replacement path. This is not a paperwork formality. It’s the difference between a legal installation and one that gets red-tagged. On a 1960s CBS home in Little Havana, our tech found the original Estate Collection single-hung windows had aluminum frames pitted from years of salt air and failed impact glazing seals. The owner had already been flagged during a re-roofing inspection for no valid NOA on file. We pulled the existing units, rebuilt the rough openings to accept new Sentinel Series impact windows, and used stainless fasteners and marine-grade flashing. The inspector passed the job on the first visit, and the homeowner’s insurance carrier dropped their windstorm premium by 12%. That’s what proper NOA documentation and the right materials actually do in Miami.
CGI Models & Products We Service in Miami
We service the full CGI residential lineup that’s common across Miami, including the Estate Collection windows, Estate Collection sliding glass doors, Sentinel Series impact windows, and Estate French doors. The approach differs by part. For structural components like impact glazing and multi-point locks, we use genuine CGI replacement parts whenever they’re available. Aftermarket pieces can fail NOA inspection or change the unit’s impact profile. For wear items like rollers, seals, and weatherstripping, we source marine-grade aftermarket options that hold up to salt corrosion and UV breakdown better than the originals often did. We stock the most common replacement parts for Miami’s most-installed CGI models, which means faster turnaround when you need a repair before a storm or a closing. Our full CGI sales & service approach covers everything from single-window repairs to full frame replacements.
CGI Service Pricing in Miami
CGI service pricing in Miami depends on the repair scope, the age and model of your units, and whether the frame is still sound. Minor hardware replacements like rollers and weatherstripping typically fall in the $150 to $400 range per unit. Failed impact glazing seals start around $350 to $600 per glass panel, depending on size. A full frame replacement with new Sentinel Series Impact Windows in Miami runs higher, and the final number moves with rough opening work, masonry repair in those older CBS block walls, and NOA documentation costs. Every estimate includes a written line-item breakdown before work starts, so there’s no guessing. We offer a free second opinion on any written estimate you’ve received, and we also offer $40 off any repair over $200. Call (904) 478-8983 for an exact number. Estimates are free.

FAQs - CGI Windows & Doors in Miami
Most likely not without verification. A 2005 CGI installation may predate the current NOA documentation standards, or the NOA may exist but the unit serial numbers no longer match what’s in the product control database. Buyers’ inspectors in Miami are stricter than almost anywhere in the country. We verify the NOA status, inspect the frames and glass for salt-air degradation, and tell you exactly what needs repair or replacement before listing. Call (904) 478-8983 to schedule a pre-sale inspection.
That grinding sound is almost always marine moisture and fine sediment pushed into the roller track channels during storms. Brickell’s east-facing high-rises get the worst of it. The rollers and stainless hinges corrode even when they look clean from the outside. We replace the roller assemblies and track channels with marine-grade components. If the frame itself is pitted, we address that at the same time. Call (904) 478-8983 and we’ll diagnose it in one visit.
No, and the answer is in the code. Jalousie louvers are prohibited under Miami-Dade’s HVHZ rules, and any existing CGI frames on a jalousie installation won’t have a valid NOA that covers that configuration. We remove the old system entirely, rebuild the rough opening in the CBS block wall, and handle your Miami Window Installation with new Sentinel Series impact windows and proper flashing. It’s a bigger job, but it’s the only path that passes inspection and keeps your insurance intact.
CGI’s current residential lineup is aluminum-specific, which is why you see their products on so many Miami high-rises. If your Edgewater HOA restricts exposed aluminum, we’ll walk you through the options. As an independent installer, we work with eight premium brands including PGT, CWS, ES Windows, and Therma-Tru, so we can match the HOA’s aesthetic requirements while keeping the impact rating the building demands. Call (904) 478-8983 and we’ll bring samples to the board meeting.
No, and it’s a red flag. Condensation between the panes means the glazing seal has failed. In Coconut Grove’s humidity and UV intensity, that failure accelerates once it starts. The bigger issue is that a failed seal means the impact rating on that glass unit is no longer what the original NOA specified. We replace the glass unit and re-verify the NOA documentation so your windows are legal and perform as rated. Call (904) 478-8983 for an exact quote.
