CGI Windows & Doors in Miami, FL | Winslow Windows & Doors
We’re an independent CGI service provider working across Miami, and our crews handle CGI windows and doors in concrete block homes and Brickell high-rises every week. The thing that makes our CGI work here different is simple: Miami-Dade County runs its own product approval system, the Notice of Acceptance (NOA), which is stricter than anything in Tampa or Orlando. Call (727) 291-4678 for a free estimate on any CGI window or door repair. We show up in uniform, background-checked, and Ed Winslow’s name is on the truck.

Why Miami Residents Choose Us for CGI Service
Most window companies in Miami can install a CGI unit. Fewer can tell you why your 700 Series single hung failed a Citizens insurance reinspection, or whether that fogged insulated glass unit in your Allapattah CBS home needs a full sash replacement or just a new IGU. That depth of CGI familiarity comes from fifteen years of working these exact buildings. Ed Winslow grew up in Little Gables, not far from the old Coral Gables Congregational Church, and he’s been measuring, installing, and standing behind windows and doors in South Florida since before the last big hurricane seasons. We’re not a manufacturer affiliate and we don’t answer to a corporate script. We answer to the homeowner standing in the living room watching the inspector check the NOA label. Every technician who knocks on your door is background-checked and in uniform, and a live person answers our phone 24/7. You get our CGI sales & service expertise without the runaround.
Common CGI Windows & Doors Problems We Solve in Miami
Here’s what we actually see in the field, week after week, in Miami’s specific climate and housing stock, from Impact Windows in Miami to standard replacements. If any of these sound familiar, call us before the insurance inspector finds them first.
- Interlocking meeting rail wear on CGI 700 Series single hungs. Years of salt-laden humidity in neighborhoods like Little Havana degrade the pile weatherstripping until the sashes no longer seal tight. We see this constantly, and it’s a common insurance reinspection failure because air and water infiltration reads as structural compromise. We replace the weatherstripping and re-square the interlock to factory spec, then re-label the unit if the original NOA tag is gone.
- Roller track corrosion on CGI 5000 Series horizontal rollers. In Brickell and Edgewater high-rises, balcony runoff and sea spray pit the aluminum track and cause the panels to bind. Miami’s salt air off Biscayne Bay accelerates this faster than inland Florida by a wide margin. We clean, de-scale, and where needed rebuild the track bed so the panel glides instead of grinding.
- Fogging between panes on CGI insulated glass units. Miami’s extreme summer humidity cycling pushes moisture past failing IGU seals, and Allapattah CBS homes from the 1960s and 70s are full of original CGI units now hitting end of seal life. If the frame is sound, we can often replace the IGU alone. If the frame is 15+ years old with corrosion, replacement makes more sense than repeated repair.
- Bowed or cracked interlock on CGI Estate casements. Wind-driven missile impacts bend the interlock rail, and if the original NOA label is gone, the whole opening can fail permit renewal. We source OEM replacement hardware when structural integrity matters, and we verify the NOA number against the home’s wind zone and roof height before we touch anything.
- Jalousie window replacement into CGI impact units. This isn’t a CGI failure mode per se, but it’s the bread-and-butter job in pre-1992 CBS neighborhoods across Miami. Citizens and private carriers are actively non-renewing policies on homes with louvered jalousies still in place. The phone rings not because the windows are drafty but because a cancellation notice just landed in the mailbox. We pull the old jalousies, reuse the buck where sound, seal to Miami-Dade TAS 203, and install NOA-labeled CGI impact units that pass inspection first try.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the part nobody outside Miami-Dade fully appreciates, and it affects every CGI window and door in the city. Miami-Dade’s Notice of Acceptance system requires every window and door to carry a product approval label tied to specific engineering drawings. In Tampa or Orlando, Florida Building Code alone suffices. Here, a Miami Window Installation must match the exact NOA number to your home’s wind zone and roof height, and your insurer verifies that label before renewing the policy. That’s a direct legacy of Hurricane Andrew in 1992 erasing entire South Dade neighborhoods. Last month our tech pulled a 700 Series single hung from a 1970s CBS house off SW 8th Street in Little Havana. The homeowner had just lost coverage after Citizens flagged the original jalousies. We replaced the full openings with NOA-labeled CGI 700 impact units, reused the existing buck, sealed to TAS 203, and the inspection passed first try. That’s the Miami standard, and it’s non-negotiable. A contractor who knows Florida code but not Miami-Dade NOA isn’t qualified to pull a permit here. We are, and we’ve been doing it for over a decade.
CGI Models & Products We Service in Miami
We work on CGI’s full NOA-approved residential lineup: the 700 Series Single Hung Impact Window, the 5000 Series Horizontal Roller Impact Window, the Estate Casement Impact Window, and the Sentinel Impact Sliding Glass Door. For critical components like sashes, hardware, and weatherstripping, we source OEM CGI parts to preserve NOA compliance and structural integrity. For non-impact cosmetic pieces like trim or screens, we use proven aftermarket equivalents to keep costs down. We stock the fast-moving parts locally for quicker Miami turnaround, so you’re not waiting on a factory shipment from Medley while a hurricane watch is posted.
CGI Service Pricing in Miami
CGI repair and replacement pricing in Miami depends on what failed and whether the frame is worth saving. Here’s what we typically see:
- Weatherstripping or interlock adjustment on a 700 Series single hung: $180-$340, usually done in one visit.
- Roller track rebuild or panel re-alignment on a 5000 Series horizontal roller: $220-$470 depending on corrosion severity.
- IGU replacement (fogged glass, sound frame): $350-$650 per sash, glass package depending.
- Full jalousie-to-CGI replacement in a pre-1992 CBS opening: $900-$1,800 per opening, installed and permitted.
- Estate Casement interlock repair or replacement: $280-$520 for hardware, more if the interlock is bowed beyond salvage.

FAQs - CGI Windows & Doors in Miami
Probably not. The NOA label is how the inspector ties your window to the approved engineering drawings, and a faded or missing label means the unit can’t be verified. We can often re-label a unit by matching the original NOA number to the product line and the home’s wind zone, but if the label is gone entirely, replacement with a new NOA-labeled CGI unit is the safer route for keeping your policy in force. Call (727) 291-4678 and we’ll tell you exactly what your inspector will be looking for.
Impact-rated laminated glass is not repairable the way a windshield chip can be filled. If the inner or outer lite is chipped or cracked, the sash must be replaced to preserve impact and NOA integrity. Bowing to pressure from insurers to “just fix it” isn’t something we do. We source OEM CGI sashes and install to factory spec so your opening stays compliant.
Yes, and we do it weekly. The buck from the original jalousie opening can often be reused, which saves money and time. From there we seal to Miami-Dade TAS 203 and install NOA-labeled CGI 700 Series units. Your insurer will want to see the product approval label tied to the home’s wind zone. Call (727) 291-4678 for an exact quote, and mention you’re replacing jalousies so we can factor in the buck condition.
CGI offers a range of standard and custom finishes, and we coordinate directly with your condo association’s design requirements and the building engineer’s wind-load specs. High-rise work adds engineering review, but we’ve navigated Brickell and Edgewater aesthetic rules enough times to know how to keep everyone happy. The key is getting the finish code approved before ordering so the panels arrive right the first time.
Yes. We de-scale the corrosion, clean the track bed, replace the rollers with OEM or proven aftermarket parts depending on whether the door carries an NOA label, and re-align the panel. Near the bay, salt spray makes this a recurring issue, so we also treat the track to slow future pitting. If the track is too far gone, replacement with a new CGI Sentinel sliding glass door often costs less than repeated track rebuilds. Call (727) 291-4678 for a quote, free of charge.
