CGI Windows & Doors in Coral Gables, FL | Winslow Windows & Doors
We provide independent CGI window and door service across Coral Gables, from the Country Club section down to the Riviera, and the one thing that sets our CGI work apart here is that we’ve been through the Historic Preservation Board review process enough times to know what gets approved and what gets sent back. Ed Winslow grew up minutes from the Biltmore, studied building construction at Miami Dade College, and has spent more than two decades installing and servicing Impact Windows in Coral Gables and other impact-rated openings in this city’s Mediterranean Revival homes.

Why Coral Gables Residents Choose Us for CGI Service
Most companies offering Coral Gables Window Installation can swap a sash or replace a roller. Far fewer can tell you whether a CGI Sentinel Impact Series casement will pass HPB review on a 1920s contributing structure, or whether repairing a corroded flush bolt makes more sense than replacing the entire French door. We’ve rebuilt CGI units on homes along Hardee Road, Columbus Boulevard, and throughout the Biltmore neighborhood, so we know these products the way you only can after taking them apart and putting them back together under Coral Gables conditions. Ed’s name is on the door, and on every job we do. We use OEM CGI replacement sashes, weatherstripping, and multi-point hardware for active product lines, because impact ratings and warranty integrity depend on exact spec parts. For discontinued CGI profiles, we source NOA-listed aftermarket components that meet Miami-Dade test standards, and we tell you up front which path applies. A live person answers our phone 24/7, not a call center. That matters when you’re standing in front of a CGI French door that won’t lock and the afternoon storm is rolling in from the Everglades.
Common CGI Windows & Doors Problems We Solve in Coral Gables
- Failed interlocking seal at the CGI casement meeting rail. Coral Gables’ mature banyan and ficus canopy traps humidity against original wood and even aluminum frames year-round. We regularly see CGI casement sashes on shaded lots where the interlocking seal at the meeting rail has compressed and started letting air and water through. The fix is usually a new OEM seal and realignment, not a new window. We know which.
- Corroded flush bolts on CGI French door astragals. This is a salt-humidity problem, not a manufacturing defect. Coral Gables sits close enough to Biscayne Bay that the air carries salt even several blocks inland, and flush bolts on French door astragals are usually the first hardware to suffer. We replace the corroded bolt, lubricate the multi-point lock, and realign the door so it engages cleanly again.
- Warped horizontal roller panels on older non-thermally-broken CGI frames. East-facing rooms in Coral Gables take morning sun that heats dark bronze frames fast. Older CGI horizontal rollers without thermal breaks can warp slightly over time, tightening the track and making the panel hard to operate. We inspect the track, the rollers, and the frame before quoting anything, because sometimes the panel is salvageable and sometimes the track needs replacement.
- Stress cracks at corner welds of CGI picture windows. When an original arched opening gets modified without proper reinforcement, stress concentrates at the corners of the welded frame. We’ve seen this on historic Coral Gables homes where a previous contractor tried to fit a rectangular CGI unit into an arched rough opening. The result is a visible crack at the weld. Full frame replacement is usually the only honest fix, and this time it should be done with a custom radius frame.
- Fogging or condensation between the panes indicating seal failure. The humidity in Coral Gables means a failed insulated glass seal shows up quickly and visibly. If your CGI window is fogging between the glass, the thermal seal has deteriorated. Depending on the model and age, we can often replace the glass unit rather than the entire sash or frame, and we’ll tell you what the CGI warranty covers before we start.
CGI Service in Coral Gables: What Local Conditions Mean for Your Equipment
Here’s the fact that separates Coral Gables from every neighboring city: the Historic Preservation Board has rejected impact-window replacements that flattened original arched openings, even when the product carried a full Miami-Dade NOA. The HPB’s design review applies to contributing structures across the city’s historic districts, and the board will not sign off on a standard rectangular CGI unit squeezed into a 1920s arched opening. That means CGI installs and repairs on many Coral Gables homes require a custom radius frame fabricated to match the original opening, a skill most window companies never need to develop because Kendall and South Miami don’t have the same overlay. We keep relationships with local fabricators who bend CGI Estate Collection and Sentinel Impact Series frames to spec, so the arch stays an arch, the NOA stays intact, and the permit doesn’t bounce. Our tech pulled a pair of original 1940s wood casements from a contributing home on Hardee Road in the Country Club section, where the HPB required retaining the arched radius. We fabricated CGI Estate Collection casements through a local bender to match the 38-inch arched opening, installed them with stainless steel anchors into the coral rock substrate, and passed both the city inspection and the homeowner’s insurance wind mitigation audit. That’s the bar in Coral Gables.
CGI Models & Products We Service in Coral Gables
We work on the full CGI lineup homeowners in Coral Gables actually have installed: the Sentinel Impact Series, the Estate Collection, the ThermaFit Series, and the Classic Line. Each has different hardware, different seal profiles, and different failure patterns. Our approach is OEM-first for active product lines, because a third-party sash or weatherstrip can void a warranty and compromise the Miami-Dade NOA the product was approved under. For discontinued CGI profiles, we source NOA-listed aftermarket components that meet the same test standards. We stock common CGI hardware and seal profiles locally so most Coral Gables service calls don’t wait on a freight shipment. For custom arched work, we coordinate directly with the fabricator and the HPB submittal. You’re getting CGI sales & service knowledge without the manufacturer’s call center and without a big-box installer’s script.
CGI Service Pricing in Coral Gables
In Coral Gables, a CGI service visit with a straightforward repair like a flush bolt replacement or weatherstripping swap typically runs $150 to $350, including the part and labor. A full sash replacement on a Sentinel Impact Series casement generally falls between $450 and $900 depending on size and glass package. Custom arched CGI units for historic Coral Gables properties are a different category entirely, often $1,800 to $4,500 per opening because of the fabrication, anchoring into coral rock substrate, and HPB review. What drives the price here more than anything is the substrate: coral rock takes longer to anchor into than poured concrete or standard CMU block, and that labor is real. Every estimate we give is line-item and fixed. You’ll see the parts, the labor, and the permit work separated. Call (904) 478-8983 for an exact quote on your CGI repair, and remember, we offer a free second opinion on any written estimate and $40 off any repair over $200.

FAQs - CGI Windows & Doors in Coral Gables
No, in nearly every case the HPB will reject a standard rectangular CGI unit installed into an original arched opening on a contributing structure. The board requires the arched radius to be preserved, which means a custom-bent CGI frame matched to the original opening. We handle that fabrication and the HPB submittal as part of the job. Call (904) 478-8983 if you’re facing this situation, and we’ll walk you through what the board will want to see.
The most common cause we see in Coral Gables is seal compression or hardware corrosion from trapped humidity under the tree canopy, not a failed operator. The meeting rail seal swells or the hinge hardware oxidizes from constant moisture exposure, and the sash binds. We clean, lubricate, and replace the OEM seal or hardware as needed, which normally restores smooth operation. If the frame has warped, that’s a different diagnosis, and we’ll tell you before doing any work.
Yes, the NOA requirement and HPB review are separate and both are mandatory. Every replacement window and door in Coral Gables, which sits inside Miami-Dade’s High-Velocity Hurricane Zone, must carry a Miami-Dade NOA regardless of what the HPB approves aesthetically. The HPB approves the design; the NOA proves the product meets hurricane code. One does not substitute for the other. We only install NOA-listed CGI products, full stop.
In most cases, we can repair just the lock. A broken or corroded flush bolt, a misaligned multi-point lock, or a stiff astragal is almost always a hardware-level fix using OEM CGI parts, which we keep in stock for faster Coral Gables turnaround. Full door replacement only becomes the right call if the frame itself has rotted, warped, or failed at a weld. Call (904) 478-8983 and describe what’s happening, and we’ll give you an honest read over the phone before we even schedule.
Fogging between panes means the insulated glass unit’s seal has failed, and whether it’s covered depends on the product’s age, the specific CGI warranty terms, and whether the original installation was done by a qualified contractor. Some CGI lines carry longer glass coverage than others. We’ll check your model and installation date and help you pursue a warranty claim if you’re eligible; if not, we can replace the glass unit rather than the entire window. Call (904) 478-8983 for a free evaluation, and we’ll give you the straight answer.
