Why Miami Beach Residents Choose Us for CGI Service
Winslow Windows & Doors has been installing and repairing CGI products since 2011. Ed Winslow grew up in Hialeah and learned glazing through Miami Dade College’s building trades program, then spent years on installations across Miami-Dade before putting his own name on the truck. That matters when a contractor is quoting Miami Beach Window Installation, because this city’s review process punishes anyone who treats it like mainland work.
We’re independent. That’s worth saying plainly. We are not owned by CGI, not manufacturer-affiliated, and not told what to recommend by a factory rep. We sell and service CGI products because they hold up here, but when a legacy Estate Collection unit needs marine-grade aftermarket hardware instead of a pricey full replacement, we say so. Our technicians are background-checked and uniformed. Ed’s name is on the door, and on every job we do.
Common CGI Windows & Doors Problems We Solve in Miami Beach
- Corroded frame corners and track pitting on horizontal rollers. Salt spray off the Atlantic eats standard aluminum within two to three years. We see pitted tracks on Sentinel Series horizontal rollers all the time in older Collins Avenue condos where the original hardware was never upgraded to marine grade.
- Fogging between panes on Estate Collection insulated glass. High humidity plus salt-laden air accelerates seal failure. Once the seal goes, the glass fogs and the NOA label means the unit has to be replaced, not just re-sealed. We source OEM factory units where CGI still supplies them.
- Warped or seized jalousie replacement sashes on Targa Series frames. Direct Atlantic sun beats on vinyl frames along Flamingo-Lummus and South Beach, and older Targa sashes warp enough that the crank mechanism binds. This is a repair we do frequently, not a replacement.
- Snapped or worn balance springs on double hung impact windows. Pre-2005 CGI models get tested hard every hurricane season. Residents close and lock every window repeatedly during storm prep, and old balance springs fail. We replace them with OEM hardware when available.
- Failed concert master sliding door rollers. Three seasons of salt and sand will ruin factory rollers. We fit stainless steel replacements and reinforced weep covers so the track drains instead of corroding from standing saltwater.
CGI Service in Miami Beach: What Local Conditions Mean for Your Equipment
Here’s the thing most CGI owners don’t learn until a project stalls: any window replacement on a contributing property in Miami Beach’s Art Deco Historic District requires a Certificate of Appropriateness from the Miami Beach Historic Preservation Board before a building permit can be pulled. The same CGI unit installed in mainland Miami gets rejected here unless its muntin profile, glass tint, and frame finish match period photographs. We’ve sat through those board reviews. Our crew recently replaced three original jalousie windows in a 1939 Art Deco walk-up on Collins Avenue between 10th and 11th Street. The old louvered glass had zero NOA approval. We ordered custom CGI Estate casements with narrower muntin spacing and a silver-anodized finish to match the original sightlines, then spent two days prepping rotted steel subframes and coordinating the first-floor flood-seal installation before the board’s inspection. That’s the job. It’s not quick, but it’s done right.
Meanwhile, this barrier island sits almost entirely inside FEMA Special Flood Hazard Areas. Door threshold heights and flood-rated bottom seals are becoming the defining spec on ground-floor units as sunny-day tidal flooding gets worse. A CGI door installed ten years ago may now be too low to keep water out during king tides. We handle those retrofits and the paperwork that goes with them.
CGI Models & Products We Service in Miami Beach
We service the full CGI lineup: Estate Collection (impact-rated single hung and casement), Sentinel Series (heavy-duty horizontal roller and fixed windows), Targa Series (vinyl impact windows for condos and mid-rises), and Concert Master (high-performance sliding glass doors). Our parts approach is simple: OEM CGI factory parts wherever they’re still supplied, and trusted marine-grade aftermarket hardware for legacy lines like the Estate Collection where the factory has moved on. Stainless steel rollers, brass hinges, reinforced weep covers. We stock those locally so Miami Beach turnaround stays short.
CGI Service Pricing in Miami Beach
Repair pricing depends on the failure and the hardware it needs. A roller replacement on a Concert Master door runs less than a full insulated glass unit swap on an Estate Collection window. What drives cost here specifically: whether the property is in the Art Deco Historic District, whether it’s a high-rise requiring rigging, and whether the existing frame still passes NOA inspection. A free estimate from us includes a written line-item quote, and we don’t change the number once work starts. Call (863) 946-5039 and we’ll put a number on your exact situation.

FAQs - CGI Windows & Doors in Miami Beach
Yes, and it happens often. On any contributing structure, the replacement unit must match the original sightlines, divided-lite pattern, and finish closely enough for the board to sign off. We handle that pre-permit review as part of the job, so you’re not left standing at a hearing alone. Call (863) 946-5039 to start the process with someone who’s done it before.
No. High-rise condo work on Collins Avenue requires HOA approval, building management coordination, and frequently high-rise rigging before any permit is pulled. We’ve navigated that process for years and can handle the communication with your association.
Because Miami Beach is a narrow barrier island with Biscayne Bay on one side and the Atlantic on the other. Constant salt spray lands on every exterior frame, hinge, and seal. Mainland cities like Coral Gables sit miles from that salt load. Marine-grade hardware retrofits fix most of it. We’ll tell you honestly which components need upgrading and which ones don’t.
It depends on the FEMA flood zone and the specific opening. In many Miami Beach ground-floor units, raising the sill is the only way to meet current flood-resistant construction standards, but that can conflict with historic sightline requirements. We evaluate both constraints together and present options that pass both reviews. Call us for the exact answer on your building.
An insert replacement fits a new window into the existing frame, while a full frame replacement removes everything down to the rough opening. In MiMo-era buildings where original frames have hidden corrosion, we often find the frame isn’t structurally sound enough for an insert. We’ll quote both approaches and recommend the one that won’t fail in five years.
