Why Miami Homeowners Choose CGI Windows & Doors
We provide independent CGI windows and doors service across Miami, from Hialeah to Coral Gables to Edgewater. Our technicians work on CGI Sentinel Series, Estate Collection, Targa, and Classic Line products every week, and we know how salt air, humidity, and hurricane cycles stress these units in ways the manufacturer’s generic documentation never covers. That’s the difference: you get a repair that accounts for Miami’s actual conditions, not a canned fix. Winslow Windows & Doors is an independent CGI service provider. We are not affiliated with or authorized by CGI, which means we answer to you, not a brand rep. Call (863) 946-5039 for a straight diagnosis and a real estimate.
Why Trust Winslow Windows & Doors for Your CGI Windows & Doors?
Ed Winslow grew up in Hialeah, where summer storms rolling off the Everglades taught him early that a bad window wasn’t just an eyesore, it was a liability. He learned construction and glazing through the building trades program at Miami Dade College, then spent years running installations across Miami-Dade before putting his own name on a truck. Today that experience means our technicians walk up to a CGI unit already knowing what they’re looking for. We’ve seen how Estate Collection doors behave after three summers of Biscayne Bay salt air. We know which Sentinel Series balances wear faster in high-rise wind exposure. We don’t learn on your house.
Our service stays warranty-safe for your CGI products. We use genuine CGI parts for critical components like balances and multi-point locks. When an aftermarket part matches or exceeds original spec and saves you real money, we tell you that honestly, with the trade-offs laid out. We never void your warranty by slapping in a cheap substitute without your knowledge. And because Ed’s name is on the door, literally, every repair leaves our shop with a standard we’d stand behind on our own homes.
Common CGI Windows & Doors Problems We Fix in Miami
Here’s what we actually see on CGI products in Miami, week after week:
- Fogging between panes on older CGI insulated glass units. Miami’s humidity averages above 70% year-round, and that constant moisture finds every micro-fracture in a seal. Once the desiccant inside the IGU saturates, condensation forms between the glass. We replace the sash or the IGU itself rather than masking the symptom, because fogged glass on an impact-rated unit means the seal integrity is compromised.
- Roller and track wear on CGI horizontal roller windows in sandy coastal areas. Sand from Miami Beach and Key Biscayne works its way into tracks, then grinds against the rollers every time the window opens. We see this constantly within a mile of the water. The fix is pulling the sash, cleaning the track, replacing worn rollers with CGI-spec parts, and reinstalling with fresh weatherstripping.
- Deteriorated weatherstripping on CGI casement and awning windows. UV intensity in Miami is brutal on rubber and felt seals. Once weatherstripping hardens and cracks, air and water start getting through, and your AC bill shows it. We replace seals with marine-grade material rated for coastal exposure, not bargain-bin gaskets that fail again in two years.
- Corrosion on CGI door hinges and hardware near Biscayne Bay. Salt air doesn’t care how good your door is. Hinges, handles, and multi-point lock components oxidize faster within a mile of the coast. We replace corroded hardware with marine-grade or stainless components, and we’ll tell you honestly if the corrosion has spread far enough that a full replacement makes more sense.
- Misalignment on CGI Sentinel Series sliding doors after storm pressure cycles. When hurricane-force winds push against a large door panel repeatedly, rollers can shift or the track can lift slightly. The door still looks fine, but it gets harder to operate every month. We realign the panel, adjust rollers, and replace any bent track sections before the problem compounds.
CGI Parts & Our Repair-vs-Replace Approach
Genuine CGI parts matter for anything structural or safety-critical: balances, multi-point locks, hinge assemblies, and impact glazing. We stock the common CGI components our Miami service calls need most, so we’re not waiting on a distributor shipment while your window sits open. For wear items like weatherstripping and rollers, we’ll recommend a high-quality aftermarket option when it matches or exceeds the original spec and costs you less. We’re direct about which parts go in and why.
Sometimes repair isn’t the smart move. When a CGI unit has multiple failures, a fogged IGU plus corroded hardware plus a failing balance, a new impact-rated replacement often costs less over five years than patching an aging window. We give you the honest math and let you decide. Call (863) 946-5039 and we’ll walk you through what your specific unit actually needs.
Our CGI Service Process - Step by Step
- 1
Diagnosis. We inspect the full unit: frame, glazing, hardware, tracks, seals. On CGI products we check for the specific failure patterns we know from Miami conditions, salt corrosion near the coast, gasket breakdown from UV, roller wear from sand. You get a written line-item diagnosis, not a verbal guess.
- 2
Repair or install. We use genuine CGI parts for critical components and quality aftermarket where it serves you better. Every repair is done to Miami-Dade code requirements, no shortcuts.
- 3
Test. For sliding doors, we operate the panel five to ten cycles after service, checking for bind, drag, or misalignment. For casement and awning windows, we verify seal compression and operational smoothness. On impact units, we confirm the glazing is secure and the frame is tight.
- 4
Warranty. Our workmanship is covered by the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. No argument, no fine print.

FAQs - CGI Windows & Doors Service in Miami
Yes. We identify your series during the diagnosis visit. The model tag is usually on the frame edge or inside the track, but even if it’s faded or missing, our techs recognize the hardware patterns and glazing details that distinguish a Sentinel from a Classic Line. Call (863) 946-5039 and we’ll tell you exactly what you have.
Yes. Fogged glass on a CGI impact unit means the insulated glass seal has failed, usually from Miami’s humidity working on an aging seal. We replace the IGU or the sash with the correct impact-rated glazing, restoring both clarity and the unit’s structural rating. Our Miami Cgi service ensures proper installation. Patching a seal never lasts. Call (863) 946-5039 for a quote on your specific window.
For structural components like balances and multi-point locks, we use genuine CGI parts because they’re engineered to the original impact rating. For wear items like weatherstripping and rollers, a high-quality aftermarket part that meets or exceeds original spec is safe and often costs less. We’ll tell you exactly what’s going in and why, and you approve it before we proceed.
Storm pressure cycles typically shift the rollers or lift a track section on CGI sliding doors, especially larger panels in areas needing Cgi in Miami Beach. Sand and debris blown into the track compound the problem. We realign the panel, replace bent or worn track components, and clean out everything that doesn’t belong. Call (863) 946-5039 and we’ll get it gliding smoothly again.
In most cases, yes. If your CGI unit predates current Miami-Dade NOA standards, we can often retrofit with updated impact glazing and reinforced hardware through our Cgi service in Hialeah and surrounding areas. However, some older frames won’t accept modern impact glass without full replacement, and we’ll tell you that honestly rather than forcing a square peg. Call (863) 946-5039 for an assessment of your specific windows.
Simple service calls like roller replacement or weatherstripping on CGI windows typically run $150 to $300. Fogged IGU replacement on impact-rated units runs higher, often $400 to $900 per sash, depending on size and series. Full replacement of a worn CGI sliding door commonly runs $2,500 to $6,000 installed, depending on dimensions and impact rating. These are Miami market ranges for Impact Windows services, not quotes. Call (863) 946-5039 for an exact price on your unit; estimates are free, and we offer $40 off any repair over $200, plus a permanent 10% discount for seniors and veterans.
