CGI Door Installation: The Lighthouse Point Owner’s Guide

CGI door installation in Lighthouse Point typically runs $1,800 to $4,200 depending on the series, impact rating, and whether the frame needs reworking for Florida Product Approval compliance. We stock CGI hardware, hinges, and track components for same-day repair on most series, and we carry full door units for replacement when the slab or frame has failed. Most Lighthouse Point owners first notice trouble when a CGI sliding door sticks in the track after a rain, or when the multipoint lock no longer draws the door tight against the weatherstrip - both signs that the roller carriage or locking mechanism has worn past tolerance.

Which CGI Models This Applies To

CGI manufactures several door product lines, and the part you need depends on the series stamped on the hinge edge or top track label. The Estate Collection uses a heavier 3-inch roller carriage with stainless steel housings rated for doors up to 450 pounds; the Sentinel Series uses a lighter 2.5-inch carriage with aluminum housings. The Estate locking mechanism is a three-point multipoint system with an 85-degree handle sweep, while the Sentinel uses a two-point system with a 45-degree sweep. We have seen Lighthouse Point homeowners order the wrong carriage because both look similar from below, but the Estate track is 0.75 inches deeper and the Sentinel roller will chatter and fail within months if forced into the wrong channel.

CGI’s impact-rated doors carry a Florida Product Approval number etched into the glass corner and printed on the frame sticker. If your door was installed before 2017, check whether the approval is HVHZ (High Velocity Hurricane Zone) or non-HVHZ; Lighthouse Point falls under Broward County wind-borne debris requirements, and a non-HVHZ unit cannot legally replace a failed door in the same opening without engineering review. We carry both OEM CGI hardware and verified aftermarket equivalents from Truth Hardware and Hoppe that meet the same cycle-testing standards; for Estate Series multipoint locks, we prefer OEM because the aftermarket versions we have tested show 15 to 20 percent faster wear in salt-air environments like the canal-front properties near Lighthouse Point Marina.

Signs Your CGI Door Installation Is Failing

• The door drags or requires shoulder force to move. This usually means the roller carriage bearings have corroded or the adjustment screw has backed out. In Lighthouse Point, we see this most often on south-facing doors where afternoon sun heats the track and accelerates grease breakdown; the roller seizes, and the user compensates by lifting the door, which bends the track.
• Visible daylight between the door and frame when closed. The multipoint lock is not drawing the door tight, or the weatherstrip compression has degraded. On CGI units, the locking points are adjustable, but once the cam has worn past 2 millimeters of play, adjustment will not restore the seal and the mechanism needs replacement.
• Condensation between glass panes on an impact door. The insulated glass unit seal has failed. CGI impact doors use laminated glass with a desiccant-filled spacer; once the desiccant saturates, usually after 8 to 12 years in Florida humidity, the unit fogs and the thermal performance drops. The glass must be replaced, not the whole door.
• The handle operates but the lock points do not engage. The internal linkage has broken or the gearbox has stripped teeth. This is a security failure, not just a convenience issue; the door may appear latched but offers no resistance to forced entry.
• Rust staining on the threshold or track. Stainless steel components in CGI hardware are grade 304, not 316, which means they resist salt air but do not eliminate it. Once staining appears, the underlying component is already losing section and will fail structurally within one to two hurricane seasons.

Replacement Cost & What’s Included

What drives the range: Estate Series hardware costs 30 to 40 percent more than Sentinel; impact-rated glass units carry a longer lead time and higher material cost; and frame rot or settlement in the opening can add reframing labor that we cannot predict until we measure. We write the price after we measure, not before, and the quote you sign is the invoice you pay. The 365-Day Done Right Promise covers all labor; OEM parts carry CGI’s warranty, and our aftermarket equivalents carry a 5-year replacement guarantee.

DIY or Call Us?

A homeowner can safely check three things: whether the track has debris (vacuum it), whether the lock points are visible and aligned (look, do not touch), and whether the door sticker shows the series and approval number (photograph it for us). What goes wrong in DIY: the roller carriage on a CGI Estate door supports 200 to 450 pounds of glass and frame, and the adjustment screw is under spring tension; releasing it without supporting the panel can drop the door on fingers or feet. The multipoint lock mechanism contains a wound torsion spring that will unwind violently if the cover screws are removed without the door secured in the open position. We have been called to Lighthouse Point jobs where a homeowner stripped the lock mounting screws, turning a $480 repair into a $1,200 frame rebuild. Measure twice, write it down, then we talk price.
