Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.

CGI Windows & Doors in Westchester, FL | Sightline Windows & Doors Olympia Heights
CGI Westchester Window Replacement typically runs $180-$450 for hardware and track repairs, while full-frame replacements with impact-rated units range from $950-$2,800 per opening depending on size and NOA requirements. We provide independent CGI service across Westchester’s CBS ranch neighborhoods, and the one thing that makes our work here different is that we verify Miami-Dade Notice of Acceptance compliance before we quote - not after we tear out your old window. Call (786) 400-2761 to schedule your free estimate.
We are an independent South Florida window and door contractor who has worked on CGI products for years, so we know their profiles, sills, and hardware inside out. Although we are not authorized by CGI, our crews regularly tear out, replace, and service CGI windows and doors across Westchester, which means we bring practical, code-savvy experience to every job. Our CGI sales & service covers everything from Series 6000 single-hung repairs to full Series 8000 slider replacements, always with the written price in your hand before any work starts.
Why Westchester Residents Choose Us for CGI Service
Sonia Raman grew up in Miami and completed her building trades coursework at Miami Dade College before spending the better part of two decades measuring, fitting, and finishing windows and doors across South Florida. She and her crew have logged steady work throughout the area - including jobs near the Bird Road corridor - long enough to know which frame profiles hold up through a South Florida summer and which ones don’t make it to the second rainy season. That history matters in Westchester, where the housing stock is unforgiving: 1950s-1970s CBS ranch homes built with jalousie windows that were never designed to meet HVHZ standards.
We carry OEM CGI replacement parts for current model lines, and when OEM is discontinued, we source aftermarket components that meet or exceed original specifications. Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3 means the person at your door matches the person on the record. Every job leaves with a documented photo record and the 365-Day Done Right Promise stamped on the paperwork. “Measure it right the first time. Everything after that is just paperwork.” That’s how we keep our change-order count close to zero.
Our Westchester service area covers the full grid of CBS ranch neighborhoods, from the original 1950s developments through the infill and enclosure projects added in later decades. We know which permits get flagged, which inspectors check frame depth, and which NOA numbers are current.
Before
AfterCommon CGI Windows & Doors Problems We Solve in Westchester
- Seal failure in original CGI IGUs. Westchester’s combination of intense UV, year-round humidity, and salt-laden air from Biscayne Bay accelerates seal degradation faster than in central Florida. We see fogged glass in CGI units that are only eight to ten years old - half the expected lifespan. The fix is a full insulated glass unit replacement with low-E coating and argon fill, or complete unit replacement if the frame lacks current NOA certification.
- Corrosion of aluminum frames and hardware. Older CGI jalousie windows and thin-profile sliders installed before HVHZ enforcement were never designed for Miami-Dade’s salt air. The oxidation creeps into corners first, then spreads to hardware pockets. In Westchester, we replace these with CGI Series 6000 impact single-hung units or Series 7000 horizontal rollers built to current NOA standards.
- Operational failure of rollers, tracks, and locks. Westchester’s humid environment traps debris in sliding door tracks, and the near-constant moisture corrodes roller bearings. CGI Series 7000 and Series 8000 sliders are particularly sensitive to track alignment - a 1/8-inch sag causes binding that worsens until the lock mechanism fails. We clean, realign, or replace the full track system depending on frame condition.
- Non-compliant installations lacking valid NOA. This is the Westchester special. Even if a CGI window carries a Florida Product Approval, it cannot be permitted here without a Miami-Dade Notice of Acceptance. We regularly find homes where previous owners installed CGI units with expired or incorrect NOA numbers. The correction is always full replacement with current-documentation units - patching is not an option.
- Florida room enclosure failures. Many Westchester homeowners enclosed back patios between the 1970s and 1990s using unpermitted CGI sliders or jalousies. When we pull a permit for window replacement, Miami-Dade inspectors flag these enclosures and require the entire structure to meet HVHZ standards. We handle the full remediation, not just the window swap.
CGI Service in Westchester: What Local Conditions Mean for Your Equipment
Even if a CGI window carries a Florida Product Approval, it cannot be permitted in Westchester unless it also holds a Miami-Dade Notice of Acceptance (NOA). Because many older CGI units predate current NOA listings, homeowners often discover they must replace all windows in a room or the entire house rather than just the failed unit, a quirk unique to Miami-Dade’s HVHZ. We learned this the hard way on a 1960s CBS ranch on SW 24th Street in Westchester where the original CGI jalousie windows had been letting in water for years. During our inspection, we found that the rear Florida room had been enclosed with unpermitted CGI sliders that lacked any NOA, so we had to bring the entire opening into HVHZ compliance. We replaced the jalousies and sliders with CGI Series 6000 impact single-hung units and a Series 7000 horizontal roller, all with valid Miami-Dade NOAs, and the homeowner passed inspection on the first try. That job started as a “simple” window repair and became a full compliance project - exactly the kind of surprise that catches less-experienced contractors and leaves homeowners with open walls and failed inspections.
CGI Models & Products We Service in Westchester
We work on the full current CGI impact lineup, including Impact Windows & Doors in Westchester: Series 6000 Impact Single Hung for standard bedroom and living room openings; Series 7000 Impact Horizontal Roller for wide openings where ventilation control matters; Series 8000 Impact 3-Panel Slider for rear walls and Florida room conversions; and CGI Impact Entry Door Series for front door replacements. Our Westchester warehouse stocks common OEM hardware, tracks, and glazing components for same-week turnaround on most service calls. When OEM parts are discontinued or back-ordered, we source quality aftermarket components that meet or exceed original specifications. Given Westchester’s HVHZ requirements, we often recommend full unit replacement over repair when the existing CGI window lacks a current NOA, because patching a non-compliant unit rarely passes inspection and leaves the home vulnerable.

FAQs - CGI Windows & Doors in Westchester
No. Hurricane rating comes from the complete assembly - frame, glazing, hardware, and installation method - not the glass alone. A CGI Series 6000 or 7000 unit must carry a valid Miami-Dade NOA for the specific opening size and application. Replacing only the IGU in a non-impact frame does not create an impact-rated window. Call (786) 400-2761 and we’ll inspect the full assembly to determine whether repair or full replacement is the compliant path.
It depends on frame condition and NOA status. If the track is clogged or rollers are worn, we clean, realign, or replace components for $220-$450. If the aluminum frame shows corrosion or the unit lacks a current NOA, replacement with a CGI Series 7000 or 8000 unit is the only compliant option. We check both during our free estimate. Call (786) 400-2761 to schedule.
Yes. We pull permits for every job that requires them, and we verify that every CGI unit we install carries a current Miami-Dade NOA matched to the opening. The NOA documentation travels with the permit application; the inspector receives copies at rough and final. This is standard on every job, not an add-on.
Because their rear patio had been enclosed with unpermitted jalousie or thin aluminum sliders that lacked NOA certification. When a contractor pulls a permit for any window work in Westchester, Miami-Dade inspectors examine the entire structure for HVHZ compliance. Non-compliant enclosures must be brought up to code - new framing, impact glazing, proper anchoring. We identify this risk during our initial survey so the scope is clear before work starts.
Yes, provided you select models with current Miami-Dade NOAs. CGI’s Series 6000, 7000, and 8000 lines are engineered for HVHZ conditions and carry the required documentation. The key is matching the right model to the opening and ensuring the installation meets NOA specifications. We specify by performance tier and price range, not by margin.
