CGI Sliding & Patio Doors: The Boca Raton Owner’s Guide

We stock and install CGI-compatible sliding and patio door systems throughout Boca Raton, with most units available same-day from our local inventory. A complete CGI sliding door replacement in Boca Raton typically runs $2,800-$5,400 installed, depending on series, size, and impact-rating requirements. Most homeowners realize something’s wrong when the door sticks in the track during humid mornings, won’t latch flush against the jamb, or lets water pool on the tile after a summer storm - usually after years of smooth operation that masked gradual roller wear or frame settlement.

Which CGI Models This Applies To

CGI’s sliding and patio door lineup breaks into three series we see regularly in Boca Raton: the Estate Series (ES) with its 2-1/4″ frame depth, the Sentinel Series with a slimmer 2″ profile, and the commercial-grade Targa Series at 2-5/8″. The label you’re looking for is a small aluminum stamp on the hinge jamb or top track, usually reading “CGI” followed by a date code and series abbreviation. If the label’s painted over - common in oceanfront homes where salt air corrodes everything - measure the frame depth with a caliper; that’s your quickest identifier.

OEM rollers, tracks, and locking hardware come from CGI’s Opa-locka facility, but we’ve found that aftermarket rollers from Truth Hardware and certain track caps from AmesburyTruth match CGI’s extrusion tolerances within 0.010″ - close enough that we warranty them the same. The exception is impact-rated glass packages: those must be CGI-certified to maintain the HVHZ (High Velocity Hurricane Zone) rating, and mixing glass sources voids the Miami-Dade notice of acceptance. We keep both OEM and verified aftermarket rollers on the truck, but we won’t substitute on the glazing.

Signs Your CGI Sliding & Patio Doors Is Failing

• The door requires shoulder weight to move. This usually means the tandem roller assembly has flat-spotted or the axle has corroded. In Boca Raton’s salt-air environment, we’ve seen rollers fail in 4-6 years near the Intracoastal, versus 10-12 years inland near Boca West - the salt accelerates bearing corrosion even on stainless hardware.
• Visible gap at the lock side when “closed.” The interlock weatherstrip has compressed past recovery, or the keep (the strike plate receiver) has wallowed out from repeated slamming. Either way, you’re losing the pressure seal that keeps water and wind out.
• Water intrusion at the sill after moderate rain. The weep system is clogged with sand and organic debris, or the sill track itself has cracked at a fastening point. CGI’s weep slots are small - 3/16″ wide - and Boca Raton’s oak pollen in March plus gecko droppings in summer make them notorious for clogging.
• Handle spins without engaging the locking points. The spindle has sheared or the mortise lock body has stripped its internal cam. This is a security issue, not just a convenience failure; a spinning handle means the multi-point lock isn’t securing the door at any point.
• Glass fogs between panes. The insulated glass unit (IGU) has lost its seal, and the desiccant inside the spacer is saturated. In South Florida’s UV load, we see this most often on west-facing doors that get afternoon sun - the thermal cycling eventually breaches the edge seal.

Replacement Cost & What’s Included

For a complete CGI sliding door replacement in Boca Raton, our installed pricing breaks down as follows:

What drives the range: size (8-foot heights add roughly 20%), glass package (Low-E + argon versus clear), and whether the rough opening needs reframing. Our quote includes the measured survey you keep, the written scope with line-item pricing, and the documented photo record - Haven Clause 1 (Have it in writing) and Haven Clause 4 (Evidence on every job). The 365-Day Done Right Promise covers labor and installation materials; the CGI manufacturer’s warranty covers the product itself.

DIY or Call Us?

Here’s what you can safely check yourself: clear the weep slots with a pipe cleaner, vacuum the track of sand and debris, and confirm the door isn’t binding on a thrown rug or shifted threshold. These are maintenance items, not repairs, and they’ll solve maybe 15% of the calls we get.

What goes wrong with DIY: adjusting the roller height without a level door risks binding the entire panel, and forcing a stuck mortise lock can shear the internal cam - turning a $180 part into a $400 assembly plus the door left unsecured overnight. The rollers on a CGI sliding door carry 80-120 pounds of glass and aluminum; if one pops free during removal, the panel can drop and shatter. We don’t recommend homeowner disassembly on units with impact-rated glass - the weight and the liability both escalate.

We’re independently operated and not affiliated with CGI, though we’ve installed their products since 2014 and maintain current spec sheets for all active series. If you’re unsure what you’ve got, text us a photo of the label or the symptom - we’ll identify it before we drive out. Measure it twice, write it down, then we can talk price.
