CGI Windows & Doors in Miami, FL

CGI Windows & Doors in Miami, FL | Winslow Windows & Doors

We provide independent CGI window and door service across Miami, from full-frame replacements in Coral Gables to roller and track rebuilds in Hialeah. The thing that separates our CGI work here is paperwork discipline: before any install, we verify the Miami-Dade NOA for that exact product line and size, because a Florida Statewide approval alone will fail a Miami inspection. Call (844) 901-4551 to talk through your CGI project or repair. We’re Winslow Windows & Doors, and we’ve been serving Miami-Dade since 2011.

Why Miami Residents Choose Us for CGI Service

We’ve been installing and repairing CGI windows and doors across Miami-Dade for well over a decade, and we understand how these products behave in this specific environment. That practical knowledge matters more than a dealership badge. We’re an independent service provider, not a CGI dealer or authorized warranty station, so our recommendations don’t come with a sales quota attached. If a CGI unit can be repaired and hold its NOA rating, we’ll tell you. If it’s better to replace it, we’ll show you the numbers and let you decide.

Our familiarity with CGI extends from the CGI sales & service work we do through every product family, and Ed Winslow grew up in Hialeah watching crews work the older concrete-block homes west of the Palmetto Expressway. He learned the trade at Miami Dade College’s Wolfson Campus construction technology program, then spent years in the field before focusing on South Florida windows and doors. Every technician we send is background-checked and uniformed. We answer the phone 24/7 with a live person, and every job is backed by our Done Right Promise: if it’s not done right, we make it right.

Common CGI Windows & Doors Problems We Solve in Miami

• Salt-air corrosion on aluminum frames and hardware. Homes within a mile of Biscayne Bay or the Atlantic get hit with salt-laden air that eats at CGI frame finishes, hinges, and locking points year-round. We see pitting and white oxidation on lower rails first, and we replace the affected hardware before it seizes entirely.
• Fogging between panes on older CGI impact glass. Miami humidity and intense UV exposure accelerate seal failure, so older CGI units start showing interior condensation that can’t be wiped off. That’s a seal failure, not a surface issue, and it usually means glass replacement rather than a repair.
• Worn or seized roller assemblies on CGI horizontal sliders. Sand and salt grit work their way into roller tracks and bearings, especially on coastal properties. The door gets progressively harder to move until the roller wheels flatten or the track grooves wear out.
• Stripped or corroded anchoring screws in CBS block. Miami’s concrete block construction requires stainless steel fasteners. We regularly open up walls on older installations and find corroded or stripped anchors that weren’t replaced when the original windows went in, which compromises the structural tie-down.
• Jalousie-to-impact upgrades failing paperwork. Many older Miami homes still have jalousie windows that offer zero hurricane protection. When we replace them with CGI impact units, the job only passes if the NOA paperwork matches the exact product and size, which is where we handle the vetting before ordering.

CGI Service in Miami: What Local Conditions Mean for Your Equipment

In the City of Miami, a window or door must carry a Miami-Dade Notice of Acceptance, not just a Florida Statewide Product Approval, or the inspector will fail the job even if that same product is perfectly legal in Tampa or Orlando. That single fact drives everything about how we approach CGI work here. We pre-vet every CGI unit’s NOA certificate against the specific product line and size before we ever schedule the install, because an NOA that covers the 3-panel slider may not cover the single-hung version. It’s the kind of detail that separates experienced Miami contractors from out-of-market crews who learn it the hard way at the inspection. For homeowners in Little Havana, Hialeah, or Miami Beach with older CBS construction, that paperwork check is just as important as the Miami Window Installation anchoring itself.

CGI Models & Products We Service in Miami

We service CGI’s main product families: the Sentinel Series, the Estate Collection, the Targa Series, and the Classic Series. For frames or sashes still under warranty or where a repair must maintain an exact NOA rating, we use genuine CGI parts. For out-of-production hardware or obsolete sealants, we source quality aftermarket components that meet Miami-Dade HVHZ requirements. We keep common CGI roller assemblies, weatherstripping, and locking hardware stocked locally so we’re not waiting on out-of-state shipments for routine Miami service calls. When a unit is over 12 years old or showing frame corrosion, we’ll price a full replacement against a repair so you can make an informed call.

FAQs — CGI Windows & Doors in Miami

Does my CGI window automatically have a Miami-Dade NOA just because it’s impact-rated?

No. A product can carry a Florida Statewide Product Approval and still lack a Miami-Dade Notice of Acceptance for your specific size and configuration. Miami-Dade County is a High Velocity Hurricane Zone with stricter testing protocols than the rest of Florida. We verify the NOA for your exact CGI product line and size before ordering anything. Call (844) 901-4551 and we’ll check your paperwork.

A neighbor said my CGI window frame needs to be anchored into concrete with special screws. Why?

Most Miami homes are concrete block and stucco construction, not wood stud framing. Impact Windows in Miami installed in CBS walls must be anchored with stainless steel fasteners set into the masonry, and the spacing and depth have to match the NOA’s engineering details. If the original install used standard screws or the anchors are corroded, the window won’t hold in a storm and won’t pass a wind mitigation inspection. We epoxy-set new stainless anchors into the block on every full-frame replacement we do in Miami.

Can you replace just the glass in my old CGI impact window that’s fogged between the panes?

In many cases, yes, if the frame and sash are still structurally sound and the NOA supports a glass-only replacement. The fogging is a seal failure, and we can install a new insulated glass unit that maintains the impact rating. If the frame shows significant corrosion or the unit is over 12 years old, we’ll price a full replacement so you can compare the long-term cost. Call (844) 901-4551 for a free estimate.

Why are my CGI horizontal roller windows so hard to open in Miami?

Salt, sand, and grit from Miami’s coastal air get into the roller tracks and bearings, wearing them down over time. The rollers flatten, the track grooves pit, and eventually the window binds. We replace the roller assemblies and clean or replace the track, and in many cases that restores smooth operation without replacing the entire unit.

Does having CGI impact windows actually lower my property insurance in Miami-Dade?

Yes, documented windstorm mitigation credits on fully impact-rated openings are a primary way Miami homeowners reduce property insurance premiums, which is a major factor given Florida’s insurance market. The key is having the NOA documentation and a passed wind mitigation inspection. We make sure every CGI install we complete leaves you with the paperwork your insurer needs to apply the credit.

In Little Havana, we replaced a row of corroded jalousie windows on a 1960s CBS house with CGI Sentinel single hung impact windows. The original frames were so eaten by salt and humidity that we cut out the old anchors with a grinder, epoxied new stainless steel fasteners into the block, and mounted the CGI frames. The wind mitigation inspection passed on the first try. That’s the standard we bring to every Miami job. My name’s on the permit. That means I’m not going anywhere until it’s right.
