CGI Impact Garage Doors: The Lantana Owner’s Guide

We stock and install CGI-compatible impact garage doors in Lantana for $2,800-$4,600 installed, depending on door size, wind-load rating, and hardware package. Most standard single-car units in the 8′ × 7′ range with a 140 mph wind rating fall between $3,100 and $3,800, and we can typically measure, order, and install within 5-10 business days for in-stock series. Homeowners usually discover the failure after a storm: the door won’t latch properly, the panels have shifted in their tracks, or the impact-rated glass has spidered but not shattered - a sign the laminated interlayer has done its job once and may not do it again.

Which CGI Models This Applies To

CGI’s impact garage door program breaks into three series that matter for Lantana homes: the Estate Series (aluminum-frame with impact glass inserts), the Sentinel Series (reinforced steel-frame for higher wind loads), and the Coastal Series (thermally broken aluminum with laminated glazing). The model number is stamped on a metal tag inside the top track housing, usually on the left jamb side, and begins with ES-, SE-, or CS- followed by the nominal width and height in inches.

The part compatibility gotcha: Estate and Coastal Series use a 2-inch track profile with nylon rollers, while Sentinel uses a 3-inch heavy-gauge steel track with sealed ball-bearing rollers. Order the wrong roller or hinge set and the door binds within ten cycles. We carry both on our trucks, but most Lantana homes built 2015-2020 have the Estate Series, and the hardware package is not interchangeable with Sentinel.

We are an independent service provider, not affiliated with CGI. For OEM parts, we order through CGI’s Florida distribution in Medley; for hardware packages where the OEM lead time stretches past three weeks, we use quality aftermarket equivalents from Clopay and Amarr that match the wind-load certification and track profile. The decision depends on what the measured survey shows: if the door slab and frame are sound, aftermarket hardware is the practical fix. If the slab is delaminating or the frame is racked, the OEM full-door replacement is the only path that preserves the impact rating.

Signs Your CGI Impact Garage Door Is Failing

• The door hangs crooked in the opening. One cable has stretched or a bottom roller has jumped the track. In Lantana’s salt air, the zinc coating on CGI’s original cable drums corrodes faster than inland specs predict, and the drum develops flat spots that throw off cable tension.
• Impact glass is cracked or spidered. The laminated interlayer absorbed impact energy and held, but the glass is compromised. Florida building code requires replacement; a cracked impact panel no longer meets the HVHZ certification stamped on the door tag.
• The door binds or stalls at the same point in its travel. The horizontal track is out of plumb, or a hinge has elongated its bolt holes. We see this on Lantana beachfront homes where the slab settled and the frame twisted slightly; the hinge takes the stress until it wallows.
• Weatherstripping is brittle or missing at the bottom. The vinyl or brush seal has UV-degraded. This seems minor, but a 9-foot-wide gap lets wind-driven rain pressurize the garage, and that pressure tests every other component in the system.
• The automatic opener strains or reverses unexpectedly. The door is out of balance, or the spring tension has dropped. Torsion springs on impact doors are heavier than standard residential springs; a failing spring overloads the opener gear set, and the opener fails next.

Replacement Cost & What’s Included

What drives the range: door width, wind-load rating (120 mph vs. 150 mph for Lantana’s proximity to the coast), and whether the existing frame is square within 1/4 inch. Our measured survey documents the rough opening dimensions, the frame plumb reading, and the wind-load zone; the written quote matches that document exactly. Every replacement carries our 365-Day Done Right Promise under the Haven Standard, and the photo record shows the door tag, the installed hardware, and the final sightline check before we leave.

DIY or Call Us?

What you can safely check: look at the door tag for the model and wind-load rating, inspect the glass for cracks, and listen for where the door binds. If the opener reverses, pull the release cord and lift manually; a properly balanced door should stay at mid-height without drifting. If it drifts, the spring tension is off.

Where DIY goes wrong: torsion springs store lethal energy. A standard residential spring holds roughly 10,000 pounds of torque; an impact-rated door spring holds more. Winding or unwinding without the proper bars and training causes serious injury. We have replaced springs on CGI doors in Lantana where the homeowner’s DIY attempt bent the torsion tube and cracked the end bearing plate, turning a $340 repair into a $1,200 door-off rebuild. We carry the correct spring charts for CGI’s door weights, and we torque to spec with a calibrated winding bar set.
