Why Westchester Homeowners Choose CGI Windows & Doors
CGI windows and doors are built for the brutal wind and salt reality of Miami-Dade County, and Westchester’s older CBS homes lean on them hard. We provide independent CGI windows and doors service in Westchester for homeowners who already trust the brand and need someone local who can repair, tune, or replace those units without sending them through a corporate service maze. As an independent CGI service provider, we are not authorized by or affiliated with CGI, but we know their products from flange to glazing bead. That means faster diagnosis, honest repair-or-replace guidance, and service that keeps your Miami-Dade Notice of Acceptance (NOA) intact. Call (863) 251-5864 when a CGI window or door starts misbehaving.
Why Trust Winslow Windows & Doors for Your CGI Windows & Doors?
Ed Winslow has spent the better part of two decades measuring, installing, and standing behind every window and door his crew puts in. Westchester has been his crew’s backyard for years, from quiet cul-de-sacs near Bird Road to older ranch homes tucked off the Palmetto. Our techs are factory-trained on CGI’s specific flange systems, balance mechanisms, and proprietary weatherstripping profiles, so we know precisely where these windows fail under Miami-Dade conditions, without the manufacturer’s red tape. Born and raised in Miami, Ed learned the trade hands-on through Miami Dade College’s Building Construction Technology program, then spent years in the field before putting his own name on the truck.
What that means for your CGI gear is simple. We do not guess. We diagnose the actual failure signature, use OEM CGI balances, rollers, and gaskets whenever a replacement part is safety or fit-critical, and we never recommend a full sash or frame replacement unless the Miami-Dade NOA label is void or the sill is beyond sealing. The 36500-Day Done Right Promise backs every repair we do. If it is not done right, we make it right. Upfront pricing. No surprises on the invoice.
Common CGI Windows & Doors Problems We Fix in Westchester
Westchester’s specific combination of slab-on-grade CBS construction, year-round humidity, and salt-laden air (even 8 to 10 miles inland) creates a predictable list of CGI failures. Here is what we see most often:
- Sash balance fatigue in Estate Collection single hungs. After repeated impact cycles, the concealed balances inside the jamb lose tension. The sash drifts down when open, or drops suddenly. In Westchester homes where windows are opened and closed daily through the dry season, we commonly see this on units installed 8 to 12 years ago. It is almost always a balance replacement, not a frame problem.
- Bowed or cracked interlocking meeting rails on 3-lite sliding glass doors. Westchester’s slab-on-grade homes settle. When the slab shifts even a quarter inch, the three panels of a CGI 3-lite slider transfer that movement into the interlocks. Cracks start at the corner welds, then the doors bind. We shim, re-align, and replace the interlock hardware before the frame gets damaged beyond economical repair.
- Compression gasket delamination on Estate casements. The fixed glass lites on CGI Estate casements rely on compression gaskets to seal the glass to the frame. After a decade of UV and humidity cycling, those gaskets lose memory and pull away at the corners. Air leaks form, the window whistles, and the thermal performance craters. We re-glaze with exact-profile gaskets and restore the original seal.
- Roller carriage corrosion in horizontal rollers. Salt spray travels further inland than most homeowners realize. The roller carriages in CGI Estate horizontal rollers corrode at the axle, producing a grinding noise and binding. We pull the panel, clean the track, and replace the carriages with OEM corrosion-resistant rollers. The panel should glide under one hand when we leave.
- Weatherstripping compression set across product lines. CGI’s proprietary weatherstripping profiles are excellent when new, but constant thermal cycling in Westchester’s heat flattens them over time. Water and air intrusion at the sill or interlocks is the result. We replace with exact-profile weatherstripping that restores the original compression and keeps the NOA engineering intact.
CGI Parts & Our Repair-vs-Replace Approach
We use OEM CGI balances, rollers, and gaskets whenever a replacement part is safety or fit-critical. Those components carry the engineering that earned the NOA approval in the first place, and swapping in a generic part is how you quietly void a hurricane certification. For non-structural items like aluminum screen frames, insect mesh, and hardware, we source aftermarket-grade materials with equal or better corrosion resistance when the original was discontinued.
Our repair-versus-replace decision is straightforward. We only recommend full sash or frame replacement when the Miami-Dade NOA label is void, the frame is out of square beyond shimming, or the sill is corroded beyond sealing. If a balance, roller, or gasket fixes the problem, that is what we do. We will not sell you a new window because the old one needed a $40 part. Call (863) 251-5864 if you want a straight answer about your CGI window or door.
Our CGI Service Process - Step by Step
- 1
Diagnosis. We inspect the unit, check the NOA label, and identify the failure signature. On a waterfront Westchester ranch, our tech pulled a CGI Estate horizontal roller that felt like it was grinding gravel. The root cause was corroded roller axles in the bottom track plus a missing interlock shim. That level of specificity tells us exactly what to fix.
- 2
Repair or install. We replace the failed components with OEM or equal-or-better parts, reset the shim, and re-align the panel. The panel now glides under one hand, and the NOA label stays intact.
- 3
Test. We cycle every repaired unit multiple times, check seal compression, and verify the latching and interlock engagement. If it does not operate like the day the factory shipped it, we are not done.
- 4
Warranty. Every CGI repair is backed by the 36500-Day Done Right Promise. If it is not done right, Winslow makes it right. Period.

FAQs - CGI Windows & Doors Service in Westchester
Is Winslow Windows & Doors authorized by CGI?
No. We are an independent CGI service provider, not a CGI-authorized dealer or warranty center. That independence means we diagnose and repair based on what the unit actually needs, not what a manufacturer program tells us to sell. Our techs are factory-trained on CGI’s flange systems, balances, and weatherstripping profiles, so the expertise is there without the corporate constraints.
Do you use genuine CGI/OEM parts?
Yes, whenever a replacement part is safety or fit-critical. OEM CGI balances, rollers, and gaskets preserve the engineering behind your NOA certification. For non-structural items like screen frames and mesh, we use aftermarket materials with equal or better corrosion resistance when the original was discontinued. We will always tell you which parts we are using and why.
How long does CGI service take?
Most CGI repairs in Westchester are completed the same day. A balance replacement on a single hung takes about an hour. A roller carriage replacement on a horizontal roller takes two to three hours including track cleaning and re-alignment. Full window or door replacements depend on permit scheduling, but standard-size CGI units typically go in within two to four weeks from order. Call (863) 251-5864 for a timeline specific to your project.
What CGI models/series do you cover?
We service and install the CGI Estate Collection Single Hung, Estate Collection Horizontal Roller, 3-Lite Sliding Glass Door, and Estate Collection Casement. Those are the product families most common in Westchester homes. If you have a different CGI series, give us a call and we will tell you honestly whether we can service it.
Will service void my CGI warranty?
Any manufacturer warranty is between you and CGI, and CGI’s warranty terms govern what independent service affects. What we protect is your NOA rating, which is separate from the manufacturer warranty and matters more to your insurance. We use OEM parts where they matter, and we never do work that compromises the Miami-Dade product approval. If a repair is beyond what can be done warranty-safely, we will tell you before we touch anything.
How much does CGI windows and doors service cost in Westchester?
CGI repair costs in Westchester typically run $180 to $340 for common issues like balance replacement or weatherstripping re-glazing. Roller carriage replacement on a horizontal roller runs $260 to $450 depending on access and track condition. Full new CGI impact window installation runs $1,100 to $2,800 per opening depending on size, series, and the retrofit work required for CBS openings. Every job gets a written line-item quote up front, and there is no trip charge inside our home county. Call (863) 251-5864 for an exact quote, estimates are free.
