CGI Door Installation: The Lantana Owner’s Guide

CGI door installation in Lantana typically runs $1,400-$3,800 for a standard single entry unit, depending on series, impact rating, and whether the frame needs replacement. We stock CGI-compatible hardware and frame components for same-day installation on most common series, and every job ships with a written quote that matches the measured survey you keep. Most Lantana owners discover their CGI door is failing when the multipoint lock won’t engage after a humid summer, or when they notice daylight between the sash and frame that wasn’t there in March.

Which CGI Models This Applies To

CGI manufactures several door series that circulate through South Florida, and the installation approach differs by frame depth, impact certification, and hardware mount pattern. We regularly install and replace units from the Estate Series (ES), Sentinel by CGI, and the commercial-grade Targa lines. The Estate Series uses a 4-9/16 inch frame depth with a proprietary multipoint lock prep; Sentinel shifts to a 5-1/4 inch frame with a different strike plate spacing. Targa commercial doors carry a heavier hinge load and require #14 x 3 inch structural screws into the king stud, not the jamb itself.

To identify your series, check the etched mark on the glass corner or the label inside the hinge stile. The AAMA certification number and the DP rating (Design Pressure) tell us whether your original install met Miami-Dade HVHZ or the slightly less stringent Florida Building Code zone. We see mismatched replacements in Lantana every month: a Sentinel slab hung on an Estate frame, which leaves the deadbolt misaligned by 3/8 inch and voids the impact rating. We stock OEM CGI hardware and select aftermarket equivalents from Truth Hardware and Hoppe that match the original specs without the six-week factory lead time. Our truck carries Estate Series multipoint gearboxes, Sentinel hinge sets, and Targa bottom sweeps because those three items account for most of the calls we field between Hypoluxo Road and the beachfront corridor.

Signs Your CGI Door Installation Is Failing

• The multipoint lock sticks or grinds. In Lantana, salt air corrodes the zinc gearbox internals faster than inland installs. We replace the full mechanism, not just the handle, because the cam levers inside are already pitted even if the exterior looks clean.
• Daylight visible at the top corner of the door. This usually means the hinge screws have backed out of the frame or the rough opening has settled. On CGI units, the top hinge carries 60 percent of the weight; when it loosens, the door racks and the weatherstrip can’t seal.
• Water stains on the interior sill after a storm. The bottom sweep or the sill pan flashing has failed. CGI’s Estate Series uses a replaceable vinyl sweep; Sentinel uses an integrated aluminum threshold that requires full frame removal to service properly.
• The door drags on the threshold in summer, then gaps in winter. This is seasonal expansion in a frame that wasn’t shimmed with composite material. We see it in Lantana homes built 2015-2019 where the original installer used pine shims that swelled and compressed.
• Impact glass fogs between the panes. The IGU seal has failed. CGI doors use a specific glazing bead profile; replacement requires the correct bead size or the glass won’t seat to the design pressure rating.

Replacement Cost & What’s Included

The range depends on three factors: whether the frame is square within 1/8 inch, whether the interior trim needs removal and replacement, and whether the original install included a composite sub-sill that we can reuse. Every quote we write in Lantana includes the measured survey, the specific CGI series and options selected, labor, disposal of the old unit, and the 365-Day Done Right Promise under Haven Clause 5: No surprises. The price on the page is the price on the invoice. We also carry PGT, CWS, and ES Windows door lines if your opening requirements have changed since the original install.

DIY or Call Us?

There is one check every CGI door owner can make safely: open the door to 90 degrees, grip the handle, and lift straight up. If you feel vertical play, the hinge screws are loose or the hinge barrel is worn. Tightening the screws with a #3 Phillips is reasonable; if they spin freely, the wood behind the jamb is stripped and the door needs to come out for proper repair.

What goes wrong in DIY: CGI multipoint locks are under spring tension and the faceplate is held by six to eight screws in a specific torque sequence. Remove them out of order and the internal cams disengage into the door cavity. We’ve retrieved broken cam levers from inside Estate Series doors where the owner saved $400 on labor and spent $1,100 on a new slab. Impact-rated doors also require re-certification after any frame modification; an unpermitted install can void your windstorm inspection. We’re not affiliated with CGI as a company; we are an independent service provider with eighteen manufacturer certifications on file, and we pull permits for every full-frame replacement in Lantana so the work passes municipal inspection. For hardware swaps, we typically schedule a morning arrival and finish before the afternoon rain. Call (561) 461-2062 to book a measured survey.
