AfterCGI Windows & Doors in Miami, FL | Winslow Windows & Doors
We provide our CGI services across Miami, and we’re the team homeowners call when an inspector flags a product-approval problem or salt corrosion has done its work. Here’s the thing that separates us from a generic glass shop: every CGI unit we install or repair in Miami must carry a Miami-Dade Notice of Acceptance (NOA) number, and we check that database on every job before we touch the frame. From the CBS neighborhoods of Westchester to the high-rise condos along Brickell Bay Drive, we know which CGI products pass county inspection and which ones will get a homeowner failed before final sign-off. Call (727) 860-0593 for CGI sales and service that actually understands Miami-Dade code.
Why Miami Residents Choose Us for CGI Service
Winslow Windows & Doors has been serving Miami homeowners and condo boards since 2011. We’re an independent CGI service provider, not a manufacturer affiliate, which means we repair and replace based on what your home actually needs, not on a corporate replacement schedule. Our teams handle CGI Sentinel, Estate, Targa, and Commercial series windows and doors across Miami-Dade, and we stock the OEM components that county inspectors recognize. Ed Winslow grew up in Brownsville and trained in building construction technology at Miami Dade College, so the product-approval system here isn’t an abstraction to him. It’s the rulebook he’s been working under since day one. When you call us, you get a live person on the phone, a uniformed technician at your door, and a Done Right Promise on the work.
Common CGI Windows & Doors Problems We Solve in Miami
- Salt-driven galvanic corrosion on CGI Sentinel casement corners. Homes within two miles of Biscayne Bay deal with sustained salt-laden air that eats at aluminum frame corners and weep-hole inserts. Mid-2000s Sentinel 7200 casements are especially vulnerable. We replace corroded corners with marine-grade stainless hardware and re-seal the weep system so water drains instead of pooling inside the frame.
- Roller-track wear and binding on CGI Targa vinyl horizontal sliders. Miami condo owners often use Targa 9300 sliders as primary ventilation, and the sill tracks collect sand, salt, and humidity grit. When the rollers bind, the sash grinds against the track. We clean and rebuild the roller assemblies with OEM or marine-grade components, then adjust the sash height so it glides without forcing the handle.
- Fogging and seal failure on CGI Estate Collection single hungs. West-facing bedrooms in Miami take brutal afternoon sun plus year-round humidity above 75%. That combination breaks down the insulating glass seal on Estate single hungs, producing condensation between panes. We replace the IG unit with an OEM impact-rated sash and re-verify the NOA number for the inspection record.
- Loose or stripped mounting screws on CGI impact windows in older CBS walls. A 1950s or 1960s concrete block home in Westchester or Little Havana can chew through cheap fasteners. When original installations used non-marine-grade screws into CBS, the anchors loosen and the window loses its impact rating. We extract the failed anchors, set new stainless sleeves into the block, and torque the mounting hardware to spec.
- Latch and locking mechanism failures on CGI Estate and Sentinel units. Salt air corrodes internal lock components, and high humidity swells or binds the latch body. We replace the locking mechanism with OEM parts, lubricate the mating surfaces with a marine-grade corrosion inhibitor, and confirm the sash still engages the frame at all contact points.
CGI Service in Miami: What Local Conditions Mean for Your Equipment
Because the city of Miami is inside Miami-Dade County, every CGI product we install must be listed in the county’s NOA database. Inspectors scan the product’s approval number during final inspection, and a CGI unit that only carries a Florida Product Approval number fails on the spot. This goes back to Hurricane Andrew’s 1992 devastation, which pushed Miami-Dade to build its own stricter product-approval system, separate from what Broward and Palm Beach counties use. For CGI owners, that means we don’t install a window or door unless we’ve pulled the NOA record and confirmed the exact model number matches the unit in the opening. We’ve seen out-of-town crews show up with Florida-approved CGI units that lack Miami-Dade NOA certification, and the rejection is automatic. Knowing which CGI products are actually legal in Miami, and which will get you failed at inspection, is exactly the kind of local knowledge you won’t get from a call center or a national chain.
CGI Models & Products We Service in Miami
Our technicians service the CGI Sentinel 7200 Series Impact Casement, the Estate Collection Single Hung, the Targa 9300 Vinyl Horizontal Roller, and the Commercial 8200 Series Fixed/Picture Window. On critical sealing and impact-rated parts, we default to OEM CGI components because Miami-Dade inspectors trace NOA numbers and aftermarket seals can derail an inspection. For hardware that sits within a few blocks of saltwater, we switch to marine-grade stainless aftermarket fasteners and hinges because the original aluminum often can’t hold up. We repair before we replace unless the frame itself is corroded through or the glass is cracked, which is rarely worth saving on a non-impact CGI unit. Our local parts stock includes the common sash balances, roller assemblies, and NOA-listed IG units for the fastest possible Miami turnaround.
CGI Service Pricing in Miami
CGI service pricing in Miami runs $145 to $395 for most repairs, including roller-track rebuilds, latch replacements, and sash re-alignment. Seal and IG unit replacement on Estate Collection single hungs starts at $210. Full-frame CGI replacements begin at $185 and climb depending on the model, glass package, and whether we’re anchoring into CBS block or wood buck. Salt-corrosion repairs near Biscayne Bay sometimes cost more because we replace hardware with marine-grade stainless instead of simply reusing what’s there. Every estimate is written, line-item, and free. We’ll show you the exact cost before any work starts, and we won’t change the number once the job is underway. Call (727) 860-0593 for an exact quote on your CGI windows or doors.

FAQs - CGI Windows & Doors in Miami
No. Miami-Dade County requires every window and door product to carry its own Notice of Acceptance number before installation and inspection. A unit with only a Florida Product Approval number will fail inspection, and you’ll be paying for a re-order. We verify the NOA record before we schedule any installation. Call (727) 860-0593 and we’ll check your product numbers for free.
Yes, and the difference is salt. Miami’s exposure to both Biscayne Bay and the Atlantic means sustained salt-laden air that accelerates galvanic corrosion on aluminum frames and hardware far more than Fort Lauderdale’s inland stretches. We recommend marine-grade stainless hardware replacement within two miles of the bay, annual weep-hole cleaning, and a corrosion inspection every two years. Call (727) 860-0593 to schedule a salt-corrosion check.
Yes. Those original single-pane jalousie windows are a defining South Florida relic with almost zero wind or water resistance, and the concrete block openings can absolutely receive Impact Windows in Miami. We anchor directly into the masonry with stainless sleeves, apply compatible flashing and sealants rated for concrete substrate, and pull the NOA record for the specific CGI model that fits the opening. The replacement is one of the highest-value upgrades you can make in a Miami home.
In most cases, yes. If the frame is not corroded and the glass is intact, we rebuild the roller assembly, clean the sill track, and adjust the sash height. We only recommend full replacement when the track is scored through or the frame has salt corrosion that compromises the impact rating. Call (727) 860-0593 for a free track-and-roller assessment.
No. Miami condo buildings are inside Miami-Dade County, so every window replacement must carry a Miami-Dade NOA number. A Florida Product Approval alone will fail the building permit inspection, and your condo association will not sign off. We handle CGI service in Miami with the NOA verification built into every quote, so you never get stuck with a unit the county won’t accept.
