CGI Impact Garage Doors: The Clewiston Owner’s Guide

CGI impact garage door replacement in Clewiston typically runs $2,800-$4,600 installed, depending on door size, wind-load rating, and whether the track and hardware need replacement too. We stock CGI-compatible impact-rated doors and hardware for most residential series, and we can measure, quote, and schedule install from a single visit. Most Clewiston homeowners realize their CGI door is failing when the opener strains, the door hangs crooked in the opening, or they notice daylight showing through a seal that used to sit flat.

Which CGI Models This Applies To

CGI’s impact garage door program centers on the CGI Impact Series and CGI Estate Collection, both engineered for High Velocity Hurricane Zone (HVHZ) compliance. The label you’re looking for is a metal tag riveted to the interior face of the bottom section, usually on the hinge side, showing the model prefix (IS- for Impact Series, EC- for Estate), nominal width and height in inches, and the Miami-Dade or Florida Product Approval number. If that tag is painted over or missing, measure the rough opening width and height, the section thickness (typically 1-3/8″ or 1-3/4″ for CGI impact doors), and count the sections. Four-section doors are standard for 7-foot openings in Clewiston; 8-foot doors often run five sections.

We carry OEM CGI track, rollers, and bottom weatherseal, plus hardware from Clopay and Amarr that meets or exceeds CGI’s original specs. One compatibility gotcha: CGI’s Estate Collection uses a proprietary 2-inch heavy-duty roller with a 7/16″ stem, while the Impact Series ships with a standard 2-inch 7/16″ roller that looks identical but carries a lower dynamic-load rating. Swapping the wrong roller into an Estate door voids the warranty and will flat-spot within two years under Clewiston’s daily thermal cycling. We verify the stem diameter and roller body width before anything leaves the truck.

Before

After

Signs Your CGI Impact Garage Door Is Failing

• The door shudders or binds at the same point every cycle. Usually a cracked or flat-spotted roller, or a section hinge that has elongated its bolt holes. CGI’s steel hinges are galvanized but not stainless; after eight to ten years near the cane fields south of Clewiston, the pivot barrel seizes and tears the hinge web.
• Daylight visible under the bottom seal, or water pooling on the garage floor after rain. The PVC bottom retainer cracks from UV exposure and repeated impact with the concrete threshold. CGI’s original retainer is a U-channel design; we replace it with an aluminum-backed retainer that won’t embrittle.
• The opener labors, reverses unexpectedly, or the motor housing gets hot. Springs have lost tension or a cable has frayed and is binding in the drum. On CGI’s torsion-spring doors, the springs are rated for 10,000 cycles; at two cycles per day, that’s roughly fourteen years, but Clewiston’s salt air and high humidity cut that to eight or ten.
• Panels show dimples, creases, or delamination at the edges. Impact-rated steel or aluminum skins can separate from the insulating core if the door takes a hit from lawn equipment or if the internal adhesives degrade in heat. Once delamination starts, the panel loses its design pressure rating.
• The manual release won’t disengage, or the door won’t stay open at half-height. Worn cogs in the opener’s gear assembly, or a torsion spring that has slipped on the shaft. Either condition puts uneven load on the door sections and will eventually twist the top section out of square.

Replacement Cost & What’s Included

For Clewiston, our installed pricing on CGI-compatible impact garage doors breaks down as follows:

What drives the range: door size, wind-load rating (Clewiston requires a minimum design pressure of +20/-20 psf for garage doors, but homes near the open cane fields may need +25/-25), and whether the existing track is square and plumb. We pull a frame reading before we quote; if the rough opening has settled or the header is deflected, we note it on the measured survey you keep, and the price accounts for shimming or reframing. No change orders after we start. The 365-Day Done Right Promise covers labor and installation; manufacturer warranties on CGI doors run twenty years on the finish and limited lifetime on the hardware.

DIY or Call Us?

There’s a safe middle ground here, and a hard stop. What you can check: whether the door is balanced (disconnect the opener and lift manually; it should stay at waist height without drifting), whether rollers are riding in the track or jumping the flange, and whether the bottom seal is physically intact. Document what you find with photos; it helps us bring the right parts.

What you should not attempt: torsion spring adjustment or replacement, cable detachment from the drum, or panel section replacement on an impact-rated door. Torsion springs store enough energy to cause serious injury or death if the winding bars slip. Impact-rated doors are engineered as a complete assembly; swapping a single panel without verifying the design pressure rating and seal continuity compromises the HVHZ certification your insurer expects to see. We are not affiliated with CGI; we are an independent service provider with no factory obligation to push OEM over quality aftermarket. Call (863) 509-1135 and we’ll schedule a measured survey. The written price you receive is the price on the final invoice.
