New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Fort Lauderdale pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
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.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

CGI Energy-Efficient Windows in Fort Lauderdale: What to Know First
As an independent CGI service provider in Fort Lauderdale, we repair and replace energy-efficient window systems from the CGI Estate Collection, Sentinel by CGI, and Targa by CGI lines - typically scheduling measured surveys within 48 hours and completing most jobs in one visit. Our written quote, generated from the measured survey you keep, is the same document that governs the final invoice; no change orders, no surprises. If you own a CGI window with failed Low-E coating, argon loss, or frame seal degradation in the Fort Lauderdale climate, call (754) 666-7478 to schedule your free estimate. We serve homeowners from Coral Ridge to Victoria Park and along the Intracoastal corridor.
How CGI Products Fail - and How We Fix Them
- Estate Collection double-hungs with argon depletion. The warm-edge spacer system in pre-2018 Estate units degrades faster in Fort Lauderdale’s high-humidity, high-UV environment than in inland Florida markets. We see pressure equalization tube corrosion that vents argon silently; the glass doesn’t crack, but the U-factor climbs from 0.30 to near 0.40 without visible warning. We source OEM replacement IGUs with upgraded stainless spacers, or match performance with quality aftermarket units that carry the same 20-year glass warranty.
- Sentinel by CGI sliding glass doors with Low-E coating oxidation at the waterline. Salt air in Fort Lauderdale beachfront properties - particularly along A1A and the barrier islands - attacks the microscopic silver layer in standard Low-E coatings when the bottom rail weep system clogs with sand and organic debris. The result is a hazy bronze band across the lower third of the glass, visible only in raking light. We disassemble the sash, clear and re-engineer the drainage path, and replace the IGU with a coastal-grade coating rated for marine exposure.
- Targa by CGI fixed picture windows with sealant creep in dark vinyl frames. Targa’s darker color options absorb enough thermal energy in direct Fort Lauderdale sun to soften the glazing tape, allowing the IGU to shift microscopically and break the primary seal. We find this most often in west-facing elevations from Rio Vista to Sailboat Bend. Our fix: remove the unit, clean the rebate to bare substrate, and reinstall with structural silicone and mechanical setting blocks sized to the specific sightline dimension.
- CGI casement operators with stripped egress hardware after energy-retrofit IGU upgrades. Heavier laminated or triple-pane retrofits overload the original crank mechanism, which CGI sized for standard dual-pane weight. We replace with upgraded stainless operators - not the stock zinc alloy - and shim the frame to maintain the designed compression against the weatherstrip.
- Sentinel impact-rated units with interlayer delamination at the sightline. The PVB interlayer in impact IGUs can separate from the glass in the 3/4-inch sightline zone when the frame has been racked during original construction or previous storm prep. We document the delamination with transmitted-light photography, then replace the entire sash assembly rather than attempting a field repair that voids the impact rating.
Before
AfterOur CGI Energy-Efficient Windows Process
- 1
Measured survey. We arrive with a printed copy of your original CGI order if available, then measure every rough opening to 1/16 inch. You keep the survey sheet; it becomes the governing document under Haven Clause 1.
- 2
Diagnostics with evidence. We use a thermal imaging camera to locate argon loss and a laser pyrometer to document surface temperature differentials. Photos go to your file before we discuss options.
- 3
Parts decision, documented. OEM CGI glass, quality aftermarket with equivalent SHGC and U-factor, or hybrid solutions - we list the part number, manufacturer, and warranty term on the written scope. No verbal commitments.
- 4
Repair or replacement. Our crew, identified by license number before arrival per Haven Clause 3, executes the work. Every fastener torque and shim placement is photographed.
- 5
Performance verification. We retest with the thermal camera, verify operation cycles, and leave you the photo record, the completed scope document, and the 365-Day Done Right Promise stamped on both.
- 6
Cleanup and closeout. We haul debris, protect your floors with the same ramboard we arrived with, and review the documentation with you on site. The invoice matches the quote exactly.

Why Fort Lauderdale Homeowners Call Sightline Windows & Doors Fort Lauderdale for CGI Work
We’ve measured, ordered, and installed windows and doors across South Florida since 2012, including a stretch of impact-rated sliding door replacements along the Intracoastal Waterway corridor near Las Olas where salt air taught us exactly how much it punishes a poorly sealed frame. That experience feeds our product failure log - a running record Sonia Raman maintains of every seal degradation pattern, spacer corrosion sequence, and coating failure we’ve encountered, which we consider more useful than any marketing claim.
The Haven Standard governs every opening: written price before work starts, verified crews with license numbers on record, documented evidence on every visit, and the 365-Day Done Right Promise stamped on the completed scope. If your CGI line has been discontinued or the lead time stretches, we specify equivalent performance from PGT, CWS, ES Windows, or ECO Window Systems - matched by U-factor and SHGC, not by what’s in our warehouse. Measure it right the first time or measure it twice on someone else’s dime.
FAQs
No, if the repair uses OEM parts or equivalent aftermarket components installed without altering the frame or sash structure. We document part numbers and installation methods to preserve any remaining warranty coverage. As an independent CGI service provider, we do not represent the manufacturer, but we warranty our own workmanship for 365 days under the Haven Standard. Call (754) 666-7478 to review your specific unit’s warranty status.
Repair is viable when the frame is square, the hardware operates, and only the IGU or seal has failed. Replacement makes sense when the frame is racked, the sash is warped, or the CGI series has known systemic issues we’ve documented in your elevation and climate exposure. We make this determination during the measured survey and put the reasoning in writing. Call (754) 666-7478 for a free assessment.
Yes, we specify replacement IGUs by U-factor, SHGC, and visible transmittance to match or improve upon your original performance. CGI used multiple Low-E coatings across production years; we identify yours with a handheld coating detector and order to that spec. The written scope lists the target numbers before we order. Call (754) 666-7478 to schedule testing.
Most single-unit IGU replacements in Fort Lauderdale are completed in two to four hours on site. Full sash replacements or multi-unit jobs may extend to a full day. We schedule based on the measured survey, not an estimate, so the time we quote is the time we use. Call (754) 666-7478 to book a survey.
We maintain specifications for discontinued CGI lines and can source compatible IGUs from our aftermarket partners or specify equivalent units from PGT, CWS, ES Windows, or ECO Window Systems. The replacement matches your opening’s performance requirements and sightline dimensions, not merely the brand name. Call (754) 666-7478 to review options for your specific series.
