AfterCGI Impact Windows & Doors in Lighthouse Point: What to Know First
As an independent CGI service provider in Lighthouse Point, we handle impact window and door repairs, replacements, and new installations across the full CGI product range, with written quotes delivered after measurement and before any work begins. Most CGI impact jobs in Lighthouse Point run from $340 for a single-hung sash replacement to $2,800 for a full opening replacement with new framing, and we typically schedule measured surveys within 48 hours of your call. This page is for homeowners who already have CGI products and need to know whether to repair or replace, what it will cost, and who will actually show up to do the work. Call (754) 600-8907 to schedule your free measured survey.
How CGI Products Fail - and How We Fix Them
- Sentinel by CGI single-hung impact windows: balance shoe fracture. The thermal-break aluminum frame expands and contracts through Lighthouse Point’s wet season, and the nylon balance shoes in pre-2018 units fatigue at the pivot pin bore. We see this most on canal-front homes east of Federal Highway where salt air accelerates the cycle. We replace with OEM balance shoes or upgrade to stainless-steel pivot versions where the frame jamb allows, and we document the frame-square reading before and after so the sash operates true.
- Impact-rated horizontal rollers: corroded stainless truck rollers. CGI’s HR6600 and HR7600 series use 440C stainless trucks that pit when track drainage is blocked by debris from Lighthouse Point’s banyan and gumbo limbo drop. The symptom is a sash that sticks mid-travel, not at the ends. We pull the sash, measure track wear with a depth gauge, and replace trucks with OEM-spec Delrin-bodied units or upgrade to sealed-bearing trucks on high-cycle openings. We also clear and verify the weep holes, because a roller fix without drainage correction fails again in 18 months.
- WinGuard vinyl impact windows: seal failure with argon loss. The dual-pane IGUs in CGI’s WinGuard vinyl line lose seal integrity when the PIB primary seal degrades under sustained UV, which in Lighthouse Point is more hours annually than most Florida zip codes. The tell is condensation at the bottom edge that does not clear by midday. We source replacement IGUs through CGI’s OEM channel with the original impact-rated laminate spec, or we coordinate with Cardinal or AGC for custom IGUs when the original production run is discontinued. We never drill and defog; the laminate layer is compromised and the impact rating voids.
- Impact entry door systems: hinge-zone frame deflection. CGI’s aluminum impact door frames, particularly on 8-foot and 10-foot units common in Lighthouse Point’s 1980s ranch renovations, can develop hinge-side jamb spread when the continuous hinge screws back out of the thermal strut. The door drags at the threshold or the multipoint misaligns. We remove the casing, verify the rough opening is still plumb, and re-anchor with structural screws through the thermal break into the jack stud, not just the fin. We then reset the multipoint and test with a 25-pound pull gauge.
- WinGuard aluminum impact windows: corroded fastener heads at the sill. The 410 stainless fasteners CGI used in coastal WinGuard frames through 2015 react with accumulated salt on the sill flange, especially on east-facing openings in Lighthouse Point that catch the onshore flow. The heads seize or shear when removal is attempted. We extract with left-hand bits or EDM if necessary, replace with 316 stainless or HCR (high-corrosion-resistant) fasteners, and seal the flange with butyl tape per Miami-Dade PA 201 application. We photograph every fastener location before and after for the job record.
Our CGI Impact Windows & Doors Process
- 1
Measured survey. We arrive with a laser measure, level, and moisture meter. You keep the handwritten field sheet. Sonia Raman still does this herself on most Lighthouse Point jobs - “Measure twice, write it down, then we talk price.”
- 2
Diagnostics with the product in place. We operate the unit through its full range, note the failure mode, and identify the series and production era from the etched mark in the glass corner or the frame stamp. This determines whether OEM parts are available or we spec quality aftermarket.
- 3
Written scope and price. The quote references the measured survey by job number. It lists parts by manufacturer or equivalent spec, labor by task, and the 365-Day Done Right Promise. No work starts until you have this document.
- 4
Repair or replacement with verified crew. Haven Clause 3: the technician who arrives is background-checked, uniformed, and identified by license number. For CGI jobs, we carry the common Sentinel and WinGuard hardware on the truck to avoid a return trip.
- 5
Testing and documentation. We operate the unit 10 cycles, check lock engagement with a feeler gauge where applicable, and photograph the completed work. The photo record uploads to your job file within 24 hours.
- 6
Cleanup and final invoice. The invoice matches the written quote line for line. If it doesn’t, Haven Clause 5 applies and we correct it at no charge.

Why Lighthouse Point Homeowners Call Sightline Windows & Doors Lighthouse Point for CGI Work
We’ve installed and serviced 18,000+ openings since 2012, and the canal-front homes near Lighthouse Point Marina have taught us what salt air and storm exposure do to aluminum and vinyl frames over time. Our crews know the difference between a Sentinel balance shoe and a WinGuard roller truck without reading the label, and we stock the common failure parts so you’re not waiting on a UPS delivery from Doral.
If your CGI line is discontinued or the lead time stretches past what your opening can tolerate, we specify from our other verified lines - PGT, CWS, ES Windows, or ECO Window Systems - matched to the performance tier your home requires, not to what we have in the warehouse. Every job carries the 365-Day Done Right Promise written into the Haven Standard, and every visit leaves a photo record you can access. Calls are answered by a live person, 24/7, because a failed impact window during storm season is not a voicemail situation.
FAQs
No, if the repair uses OEM-spec parts and documented procedures - but CGI’s warranty on older series is often prorated or expired by now. We verify your unit’s production date from the etched mark and tell you exactly what coverage remains before we start. If the warranty is active, we coordinate with CGI’s claims process and document our work to their requirements. Call (754) 600-8907 and we’ll check your coverage during the free estimate.
OEM parts for current Sentinel and WinGuard series typically arrive in 5-10 business days from CGI’s Doral distribution center. For discontinued lines, we source equivalent-spec aftermarket or coordinate custom fabrication, which can extend to 3-4 weeks. We tell you the lead time in the written quote, not after you’ve signed. If your opening is compromised, we discuss temporary secure options while we wait.
Repair when the frame is square, the finish is intact, and the failure is isolated to a component - balance, roller, or IGU. Replace when you have multiple seal failures, frame corrosion at the sill, or the series is discontinued and parts are unobtainable. We make this recommendation in writing with a side-by-side price for both options, not a sales push toward the higher ticket. Call (754) 600-8907 for the measured survey that lets us give you a real answer.
CGI’s anodized and painted finishes have shifted slightly over production years, and coastal fading in Lighthouse Point makes matching by eye unreliable. We bring a color chip set to the survey, match under natural light, and if necessary order a sample panel for your approval before the full unit is fabricated. The quote includes the finish verification step at no extra charge.
Yes, when the replacement involves a new frame or changes the opening dimensions. Lighthouse Point Building Department requires permits for window and door replacements that alter the envelope, and we pull them as part of the scope. The permit fee is listed separately on your quote, and we schedule the inspection. If your job is component-only repair with no frame removal, no permit is required, and we note that in writing too. Call (754) 600-8907 to clarify your situation.
