CGI Windows & Doors in Coral Gables, FL | Winslow Windows & Doors
We service and install CGI windows and doors across Coral Gables, including Board of Architects-approved replacements on contributing Mediterranean Revival homes. The short version: if you own CGI products in Coral Gables, we’re the crew that knows both the hardware and the city’s unique aesthetic review process. Ed Winslow has spent well over a decade focused exclusively on South Florida windows and doors, and his name sits on every permit we pull. For independent CGI service from a local Coral Gables team, call (844) 901-4551.
Why Coral Gables Residents Choose Us for CGI Service
We are an independent CGI service provider. We are not factory-authorized, not manufacturer-affiliated, and we don’t pretend otherwise. What we are is a locally owned Coral Gables-area company that has pulled, rebuilt, and reinstalled CGI windows and doors on hundreds of homes in this city, including replacements that required Board of Architects sign-off. Our expertise comes from field time with CGI hardware, frame profiles, and Miami-Dade NOA paperwork, not from a training manual.
Ed Winslow grew up in Hialeah and learned the trade formally at Miami Dade College’s Wolfson Campus before spending years in the field. That background matters when you’re dealing with 1920s coral rock walls and CGI frames that have to fit openings built before standardized measurements existed. We answer the phone at (844) 901-4551 with a live person, 24/7. No voicemail loops, no call centers. When you call about CGI service in Coral Gables, you get someone who has actually cut into coral rock walls and knows what’s behind the stucco. For broader context on how we approach the brand, see our CGI sales & service page.
Common CGI Windows & Doors Problems We Solve in Coral Gables
- Seized or sloppy cam locks on Estate Collection casements. Salt air attacks zinc-plated hardware fast, and near the Biltmore golf course we see irrigation mist adding minerals to the mix. The locks either bind up or go loose, leaving the sash unable to seal properly against wind-driven rain.
- Fogging between insulating glass panes. When the desiccant inside the IGU saturates, condensation forms permanently between the glass. Northern exposures under Coral Gables’ continuous canopy shade and high humidity make this a recurring issue. The fix is an OEM replacement IGU, not a defogging kit.
- Worn or split wool pile weatherstripping on horizontal rollers. Salt-laden air that slips past degraded weatherstripping corrodes the roller track, and the sash starts binding. By the time the window is hard to move, the track usually needs cleaning and the rollers need replacement.
- Failed sealant at the frame-to-wall joint on stone-clad openings. Original installs on coquina and stone surrounds often used sealant that hardens and separates over time. Water gets behind the wood buck and rot sets in at the jamb. This one is especially common on the older Merrick-era homes.
- Arch-topped CGI units that never fit quite right. We regularly see arched openings that were force-fitted with stock rectangular frames and packed with caulk. The Coral Gables homes that still have original arched steel casements need custom frame work, not shims and hope.
CGI Service in Coral Gables: What Local Conditions Mean for Your Equipment
Here’s the thing nobody tells you about owning CGI windows in Coral Gables: Miami-Dade County code says any impact product must carry an NOA, but the city’s Board of Architects can reject that same NOA-approved window or door if it doesn’t match the protected Mediterranean Revival character of your home. This is a city-specific review body with no equivalent in neighboring Miami or unincorporated Miami-Dade. On contributing structures, exterior window and door replacements need period-appropriate profiles, arched openings where the original had them, and decorative ironwork details that George Merrick’s 1920s design standards demand. A CGI Estate Collection casement that sails through inspection in Doral can be sent back for aesthetic review on San Sebastian Avenue. That’s not a hypothetical. We’ve worked through it. Our crews handle this by pairing CGI’s slimmer Estate Collection frames with custom exterior muntins and coquina-colored trim, so the NOA approval and the aesthetic review both pass.

CGI Models & Products We Service in Coral Gables
We service and install Impact Windows in Coral Gables from the CGI Estate Collection, including casement, single hung, and horizontal roller styles, plus the CGI Targa Series impact doors. When a part needs replacing, we use CGI OEM components: glass units, rollers, locking hardware. NOA assemblies require exact component matches for code compliance, and aftermarket parts can void that approval. What we stock locally for Coral Gables turnaround includes common roller assemblies, cam lock sets, and weatherstripping. Glass units are ordered to spec because each IGU is cut for its specific frame. If your frame is bent, deeply corroded, or the glass is shot, replacement is often cheaper than repairing a unit built as a welded, factory-sealed system. We’ll tell you which way makes sense before any work begins.
CGI Service Pricing in Coral Gables
CGI service pricing in Coral Gables depends on what failed and how much of it. Here’s what typically drives the number:
- Replacing a cam lock or roller assembly: typically $85 to $185 per window, parts and labor.
- Replacing a fogged IGU in an Estate Collection casement: typically $275 to $475 per sash, depending on glass size and whether the unit has decorative muntins.
- Full-frame replacement of a CGI window in a Coral Gables arched opening, including the custom buck work to preserve coquina sills: typically $1,200 to $2,600 per opening.
The arched-opening work is Coral Gables-specific. You won’t see that line item on a quote in Kendall. The custom beveled buck and masonry cuts required to preserve decorative surrounds add labor that standard replacement crews don’t plan for. Our free estimates include a written, line-item scope so you know what’s involved before we cut anything. Call (844) 901-4551 to schedule yours.

FAQs — CGI Windows & Doors in Coral Gables
Yes, if the installation preserves period-appropriate sightlines. We’ve done it. The Board cares about exterior appearance: frame width, muntin pattern, and how the new window sits in the original opening. For contributing structures, we pair CGI’s slimmer Estate Collection frames with custom exterior muntins and coquina-toned trim so the NOA approval passes aesthetic review. The structural product stays CGI. The visual details match Merrick’s 1920s design standards. Call (844) 901-4551 for a site assessment, and we’ll tell you whether your specific home triggers review. Estimates are free.
No, and removing it can trigger a Board of Architects re-review you could have avoided. On San Sebastian Avenue in the Country Club Section, our crew replaced two original arched steel casements with CGI Estate Series impact units. The old frames were mortared into the coral rock with decorative coquina sills. We made a clean cut just outside the original buck and set the new frame on a custom beveled buck, so the coquina sill stayed intact and no re-review was triggered. Preserving original ornamental details is part of the job in Coral Gables, not an add-on.
The wool pile weatherstripping wears or splits, salt-laden air gets into the track, the roller assemblies corrode, and the sash starts dragging. The fix is replacing the weatherstripping and rollers, then cleaning the track. With OEM parts. Near the bay, this is a maintenance item, not a defect. Call (844) 901-4551 if your rollers are binding. We’ll quote it over the phone after a few questions.
Yes. The NOA covers structural and wind-load performance. It says nothing about aesthetics. Coral Gables’s Board of Architects has its own review for exterior alterations on contributing structures, and a window can pass one review and fail the other. That’s why Coral Gables Window Installation requires a contractor who understands both code bodies, not just the product spec sheet. Our work on these homes is documented, and we can walk you through what the Board will ask for before you buy anything.
It’s one of the better off-the-shelf options, because the Estate Collection frames are slimmer than most impact-rated aluminum systems. The original steel casements on Merrick-era homes have a thin sightline that big, chunky impact frames ruin. With custom exterior muntins and the right trim, the CGI Estate casement reads close to the original. It won’t be identical, and we’ll tell you that upfront. Call (844) 901-4551 for a free estimate, and we’ll show you comparable installations in Coral Gables so you can judge for yourself.
