CGI has been a staple in South Florida impact-rated openings for decades, and their vinyl-frame units are common across Lighthouse Point’s canal-front homes. The city’s dense waterway grid exposes every elevation to salt air, not just the ocean side, which means CGI hardware and seals corrode faster here than in landlocked Broward cities. At the same time, every permitted window or door replacement in Lighthouse Point must carry a Miami-Dade Notice of Acceptance for impact resistance, so aging CGI units often need service that preserves their HVHZ compliance. We are not affiliated with or authorized by CGI. We are an independent service provider that knows these products from field experience.

Why Trust Sightline Windows & Doors Lighthouse Point for Your CGI Windows & Doors?

Our crews have provided CGI repair in Pompano Beach, Lighthouse Point, and across Broward and Palm Beach County for years. We know how CGI vinyl profiles, laminated glass units, and roller hardware behave in salt air and wind-driven rain. Sonia Raman, who leads our operation, grew up in Miami, studied building construction technology at Miami Dade College, and spent the better part of two decades measuring and finishing windows and doors across South Florida. She and her crew have worked jobs throughout Lighthouse Point, including installations along the canal-front properties near the Lighthouse Point Marina, where salt air and storm exposure make product selection genuinely consequential.

Because we are independent, we diagnose CGI failures honestly. We are not pressured to push new units when a repair solves the problem. Our background-checked, uniformed technicians carry license numbers on record, and every job leaves a documented photo record under our Haven Standard. The 365-Day Done Right Promise applies to every CGI repair we complete. Measure twice, write it down, then we talk price.

Common CGI Windows & Doors Problems We Fix in Lighthouse Point

• Laminated glass hazing and edge seal failure on CGI Sentinel and Estate series. The interlayer in CGI impact-rated laminated glass can yellow or fog after years of UV exposure, especially when coastal humidity attacks the edge seal. We see this on south and west exposures in Lighthouse Point where afternoon sun hits hardest. The glass unit is replaceable without touching the frame, preserving your NOA compliance and avoiding a full window replacement.
• Sash sag and latch failure on CGI 9000/9500 series double hung impact windows. The vinyl sash can lose plumb at the lock rail, making the window hard to close and creating an air and water leak path. This is usually a balance and sash-rail issue, not a frame problem. We replace the balances, realign the sash, and test the lock engagement before we leave.
• Flat-spotted or corroded rollers on CGI Legacy series sliding glass doors and 9500 series horizontal rollers. The original nylon or steel wheels flatten under load and salt air corrodes the axle bearings. The panel jumps track or becomes stiff to operate. We stock sealed stainless rollers that outlast the originals in coastal conditions.
• Weatherstripping compression set and gasket separation on CGI Estate entry doors and horizontal rollers. Coastal UV and humidity harden the compression seals and cause them to pull away at corners. On a Lighthouse Point home we serviced near the Intracoastal, the bottom corner seal had separated enough to admit wind-driven rain during squalls. We reset the seal and replaced the sweep.
• Frame oxidation and fastener corrosion on older CGI aluminum-frame units. While CGI’s newer lines are vinyl, some homes still carry earlier aluminum frames that have oxidized into the CBS rough opening. The frame itself becomes the failure point, and repair is not viable. We document this with photos and provide a written replacement scope.

CGI Parts & Our Repair-vs-Replace Approach

We carry OEM-spec laminated glass units, balances, rollers, and weather seals for CGI whenever they are available. When OEM components are discontinued or on long lead times, we use trusted aftermarket equivalents that match the original performance spec. The frame and sash are usually the durable part of a CGI unit, so we focus on repairing or upgrading the glass, hardware, and gaskets before recommending full frame replacement.

Our stance is straightforward: if a repair restores the unit’s function, preserves its impact rating, and costs less than replacement, we write that scope. If the frame is compromised, the NOA documentation is missing, or the unit is pre-HVHZ and cannot be brought to code, we document why and quote replacement honestly. Every option comes with a written price before work starts. Call (754) 600-8907 for a free estimate and we will review what your CGI unit actually needs.

Our CGI Service Process - Step by Step

1. 1
   Measured diagnosis. We inspect the CGI unit, identify the series, document the failure mode with photos, and record frame and sash measurements. You keep the measured survey.
2. 2
   Written scope and price. We specify the parts needed, OEM or equivalent, and write the exact price. This document does not change once work begins. Haven Clause 1.
3. 3
   Repair or install. We source CGI-compatible components, replace the failed element, and verify operation. For glass units, we confirm the new laminate carries appropriate impact documentation.
4. 4
   Testing and adjustment. We cycle the unit through full operation, check lock engagement, verify weather seal compression, and confirm drainage path clearance on weep holes.
5. 5
   Documentation and warranty. We provide the photo record, the completed scope document, and the 365-Day Done Right Promise in writing.

CGI Products We Service & Install in Lighthouse Point

Alongside our Window Installation services, we service and install CGI Sentinel series impact windows, CGI Estate series impact windows and doors, CGI Legacy series sliding glass doors, and CGI 9000/9500 series impact single hung, double hung, and horizontal roller units.

For glass unit replacement, we order OEM-spec laminated units with proper NOA documentation for Lighthouse Point’s HVHZ requirements.

Our emphasis on this page is three categories where CGI excels and where we do our highest volume of service: double hung impact windows, horizontal roller and sliding impact windows, and hurricane-proof front and entry doors.

We Also Service These Brands

We are multi-brand technicians, not single-brand dependent. Our eight verified manufacturer lines include PGT, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux alongside CGI. We specify by what the opening requires, not by what is in stock. If your Lighthouse Point home carries mixed brands from a prior install or addition, we can service them all under one scope and one written price.

We use warranty-safe practices and compatible components. We cannot extend or enforce a manufacturer’s warranty on their behalf, but we document our work so you have a record if a manufacturer claim is needed. Our own 365-Day Done Right Promise covers our labor and installation.
