CGI Windows & Doors in Davie, FL | Sightline Windows & Doors Davie
Impact Windows & Doors in Davie require service from technicians who understand both the CGI product line and Broward County’s High-Velocity Hurricane Zone permitting. We provide independent CGI repair, resealing, hardware replacement, and full-frame installation across Davie, with every job priced in writing before work begins under our Haven Standard. Because Davie’s older ranch homes carry original non-impact aluminum units that predate modern code, the retrofit market here is larger and more technically demanding than in counties just north of the Broward line. Call (754) 254-8492 to schedule your free measured survey.
Why Davie Residents Choose Us for CGI Service
We’ve worked on enough Davie homes to know the difference between a retrofit and a full-frame replacement before we step through the door. Sonia Raman, our owner, picked up glazing fundamentals at Los Angeles Trade-Technical College and spent two decades in every phase of window and door installation before bringing that field experience to Davie. Her crew has handled jobs in Pine Island Ridge, where the 1970s CBS ranch homes often need full-frame tearouts because the original aluminum frames are too deteriorated for insert windows.
We are not CGI-authorized, and we make that clear because it matters. Our loyalty is to your home’s wind-load math and the Miami-Dade NOA documentation Broward County requires, not to a manufacturer’s sales quota. When we source parts for a CGI unit, we use genuine CGI components where they’re still manufactured, then switch to aftermarket rollers, hinges, and structural gaskets rated for HVHZ exposure once a unit is out of OEM production. Our estimators have processed enough Broward County permit packets that we can tell you in one visit whether your project needs a stock CGI frame or a custom-ordered HVHZ unit with extended lead time.
Every visit starts with a measured survey you keep. The written quote cannot differ from that document. That’s Haven Clause 1, and it’s been non-negotiable since we opened in 2012.
Common CGI Windows & Doors Problems We Solve in Davie

- Failed glazing seals and internal fogging on early Sentinel dual-pane impact units. Davie’s inland salt-air intrusion plus extreme UV degrades the edge seal before the laminated glass itself fails. The glass looks cracked from the inside, but it’s actually moisture between panes. We reseal units with intact glass and sound frames; once the interlayer delaminates, replacement is the only compliant path.
- Corroded frame and sill corners on CGI aluminum impact frames. The bottom rail sits low to grade on Davie’s ranch homes, and irrigation overspray combined with horse-paddock moisture attacks the drainage weep holes. We see this on properties off Stirling Road where the rear yard stays damp. Frame corner rebuilds work if caught early; once pitting penetrates the extrusion, full replacement is necessary.
- Hinge and roller hardware fatigue on oversized CGI slider panels. Davie’s equestrian-zoned properties routinely have 8-foot, 10-foot, even 12-foot sliding glass doors opening to paddocks. The roller load on these wide panels exceeds what a standard 6-foot slider sees, and the hardware fatigues faster. We upgrade to heavy-duty aftermarket rollers rated for the actual panel weight.
- Miami-Dade NOA label degradation or loss on older CGI units. This is a documentation failure, not structural, but it kills permits and complicates resale. Broward County inspectors will red-tag a job without visible approval labels. We research the original NOA and source replacement documentation where possible, or specify a current-NOA replacement unit that satisfies today’s code.
- Non-impact original aluminum sliders and jalousie windows that predate HVHZ requirements. Most Davie ranch homes built before 1992 carry these. They cannot be repaired to compliance; they must be replaced with Miami-Dade NOA-rated impact units. We measure the rough opening, verify the wind-load zone, and specify the correct CGI Sentinel product for the exposure.

AfterCGI Service in Davie: What Local Conditions Mean for Your Equipment
Davie sits roughly 10-12 miles inland, but that distance doesn’t spare its windows from salt-air intrusion and UV oxidation. The town’s identity as Broward County’s horse country created a housing stock of sprawling 1970s-1980s single-story ranch homes on half-acre lots, most with original non-impact aluminum windows and wide sliders that predate the HVHZ code entirely. Because Davie is fully within Broward County’s High-Velocity Hurricane Zone, every replacement window and door must carry a Miami-Dade Notice of Acceptance before the permit office will issue a tag. This makes Davie’s retrofit market exceptionally permit-intensive compared to Palm Beach County just north, where Florida Product Approval alone often suffices.
The custom-width problem is specific to Davie’s equestrian zoning. On streets off Stirling Road and Griffin Road, ranch homes open onto rear paddocks through 8-foot-or-wider aluminum sliders. These openings need impact sliding units with a valid Miami-Dade NOA in that custom width. Most manufacturers, CGI included, keep these only as built-to-order. Lead times run longer than in a standard Broward suburb, and the labor cost reflects the heavier laminated panels, upgraded rollers, and re-flashed sills required to handle the load. We’ve learned to warn Davie homeowners about this timeline upfront, because quoting a stock 6-foot slider and discovering a 10-foot rough opening wastes everyone’s time.
On an equestrian-zoned stretch off Griffin Road we replaced an original 12-foot, three-panel non-rated aluminum slider that had lost its glazing seals and was draining paddock-side water into the track. Because the opening was wider than any stock CGI size, we ordered a custom HVHZ impact slider under its Miami-Dade NOA, re-flashed the sill, and upgraded the rollers to carry the heavier laminated panels. The homeowner finally passed inspection and stopped mopping the track after every storm.
CGI Models & Products We Service in Davie

We work on the full CGI Sentinel impact line and the earlier aluminum Series units still found in Davie homes:
- CGI Sentinel impact sliding glass doors - including custom-width units for oversized openings
- CGI Sentinel impact single hung and double hung windows
- CGI Sentinel impact horizontal roller windows
- CGI aluminum Series impact French and entry door systems
For frame rebuilds and hardware, we source genuine CGI replacement components where they still exist. Once a unit is out of OEM production, we switch to quality aftermarket rollers, hinges, and structural gaskets rated for HVHZ exposure. Our Davie warehouse stocks common Sentinel hardware and gaskets for faster turnaround on standard sizes. Custom-width sliders ship from CGI’s facility; we track the order and schedule installation for the day after delivery to minimize your exposure gap. CGI sales & service details our full product approach.

FAQs - CGI Windows & Doors in Davie
Broward County requires a Miami-Dade Notice of Acceptance for all replacement windows and doors in its High-Velocity Hurricane Zone. Florida Product Approval alone is not sufficient here. Davie sits fully within this zone, unlike counties just north of the line. We verify the NOA on every unit we specify and include the documentation in your permit packet. Call (754) 254-8492 if you want us to check the rating on a unit you’re considering.
Yes, but it requires a custom-ordered unit. CGI Sentinel impact sliders are available in widths exceeding 8 feet under Miami-Dade NOA, but these are built-to-order with lead times typically longer than stock sizes. We measure your rough opening, confirm the wind-load exposure, and specify the exact unit. The alternative is a standard-width unit with sidelite panels, which we discuss if the timeline doesn’t work. Call (754) 254-8492 to schedule the measured survey.
If the laminated glass is intact and the frame corners are sound, resealing is usually the honest call. We remove the sash, clean the cavity, install new structural gaskets, and pressure-test the seal. Once the laminated interlayer has delaminated or the frame corner has pitted through, replacement is the only compliant option because the unit will not pass inspection. We tell you which category you’re in during the first visit. Call (754) 254-8492 for a free assessment.
The panel weight. Davie’s equestrian-zoned ranch homes off Stirling and Griffin Road routinely have 8-foot to 12-foot sliders opening to paddocks. These wide panels load the rollers at 1.5 to 2 times the weight of a standard 6-foot unit, and the hardware fatigues faster. Add salt-air corrosion and paddock moisture at the sill, and the service interval shortens further. We upgrade to heavy-duty aftermarket rollers rated for the actual load when we service these. Call (754) 254-8492 if your slider is sticking or jumping the track.
We service and replace CGI units regardless of who installed them originally. We are not authorized, affiliated with, or employed by CGI. We are an independent Miami-Dade and Broward HVHZ permit-and-install shop devoted to CGI impact products. Our loyalty is to your home’s wind-load math and the NOA documentation required for permit approval, not to a factory quota. This independence means we can source genuine CGI parts where available, switch to quality aftermarket components where necessary, and recommend repair versus replacement based on what the opening actually needs. Call (754) 254-8492 to schedule your free estimate.
