1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

CGI Door Installation: The Clewiston Owner’s Guide
CGI door installation in Clewiston typically runs $2,800-$6,400 for a standard single entry unit, depending on series, impact rating, and whether the rough opening needs reframing. We stock CGI-compatible frames, sills, and hardware for same-day starts on most Series 3750, 3850, and Estate Collection units, and we carry PGT, CWS, and ES Windows lines for cross-reference when a match is tight. Most Clewiston homeowners find us after water stains appear at the threshold, the door sticks in summer humidity, or they spot daylight through a frame that used to sit square.
Which CGI Models This Applies To

CGI marks its door series on a metal tag inside the hinge stile or on the top edge of the frame behind the brickmould. The Series 3750 and 3850 are the bulk of what we see in Clewiston, particularly in homes built between 2015 and 2022 near the U.S. Sugar Corporation corridor where wind-borne debris requirements tightened. The Estate Collection uses a heavier 3-inch frame and a different sill profile that is not interchangeable with the 3750/3850 line.
We verify the series before quoting because CGI changed its sill pan design in 2019. The pre-2019 pans drain differently and mate to a distinct threshold extrusion. Order the wrong one and you are cutting concrete or ordering twice. We stock both generations on our Clewiston truck, plus the stainless steel hinge screws that CGI specifies for its impact-rated assemblies. Generic hinge screws will thread but will not carry the shear load the Miami-Dade notice of acceptance requires.
Sightline Windows & Doors Clewiston is an independent service provider with no affiliation to CGI. We source OEM frames and sills through CGI’s Florida distribution network and keep quality aftermarket weatherstrip and sweep assemblies on hand for faster turnaround when the frame itself is sound.
Before
AfterSigns Your CGI Door Installation Is Failing
- Water pooling at the threshold after rain. The sill pan weep holes are clogged with construction debris or the pan has separated from the threshold extrusion. In Clewiston’s summer humidity, this accelerates subfloor rot within two seasons.
- Door sticks at the top corner in summer, gaps in winter. The frame is racking in a rough opening that was not shimmed to CGI’s 1/4-inch tolerance, or the hinge screws have backed out of the king stud.
- Daylight visible between the frame and the jamb. The foam sealant has degraded or the frame fasteners have corroded. Coastal air inland from the Everglades carries enough salt to pit galvanized screws in six to eight years.
- Glass fogs between the panes on a door lite. The insulated glass unit seal has failed. CGI uses a specific spacer bar width that must be matched for the lite to seat correctly in the door stile.
- Lockset binds or the deadbolt misses the strike. The door slab has settled on a compressed sill or the frame has shifted. Adjusting the strike plate without checking the sill first masks a bigger problem.
Replacement Cost & What’s Included

| Scope | Price Range in Clewiston |
|---|---|
| CGI Series 3750/3850 slab and frame, standard size | $2,800-$4,200 |
| CGI Estate Collection, single entry | $4,600-$6,400 |
| Rough opening reframe or sill pan replacement | $680-$1,400 additional |
| Insulated glass unit replacement in existing door | $340-$580 |
| Hardware upgrade to stainless or coastal-grade | $180-$320 |
The range reflects three variables: whether the existing frame is square within CGI’s 1/4-inch tolerance, whether the sill pan needs replacement or just cleaning, and whether the interior trim can be saved or must be matched. Our measured survey gives you one written price that includes the door, installation, sealant, insulation, and disposal of the old unit. The quote you keep and the final invoice are the same document. Haven Clause 1.
Every CGI door installation carries our 365-Day Done Right Promise. If the threshold leaks, the lockset binds, or the weatherstrip compresses unevenly, we return and correct it. The promise is written into the Haven Standard, not offered as a courtesy.
DIY or Call Us?
An owner can safely check three things: whether the weep holes in the sill pan are clear, whether the hinge screws are tight to the frame, and whether the weatherstrip is intact without compression set. Use a flashlight and a stiff wire, not a screwdriver that will scar the finish.
Where DIY goes wrong is in the rough opening. CGI impact-rated doors weigh 180 to 240 pounds for a standard single unit, and the frame must be held plumb and square while the fastener pattern is drilled to Miami-Dade spec. A frame that goes in twisted preloads the hinges and guarantees failure in eighteen months. We have pulled and reframed enough homeowner attempts in Clewiston to know the pattern. The second install costs more than the first because the trim is already cut and the original measurements are lost.

FAQs

A properly installed CGI impact door should perform for twenty to twenty-five years in Clewiston, though the sill pan and weatherstrip typically need attention at eight to twelve years due to UV exposure and the area’s high humidity. Call (863) 509-1135 for an exact quote on replacement - estimates are free.
Glass unit replacement, hardware swaps, and weatherstrip renewal are practical repairs; a racked frame or corroded sill pan generally warrants full replacement because the structural integrity of the impact rating is compromised. Call (863) 509-1135 for an exact quote - estimates are free.
A standard CGI Series 3750 or 3850 replacement in a square rough opening takes four to six hours; a reframe or sill pan replacement adds two to three hours. We finish in one day and leave a documented photo record. Call (863) 509-1135 to schedule.
We stock the most common 3750/3850 frame and sill configurations on our Clewiston truck, with next-day access to the full CGI catalog through Florida distribution. Estate Collection units typically require a five-to-seven-day order cycle. Call (863) 509-1135 to confirm availability for your series.
Sonia Raman grew up in Miami and completed her technical training at Miami Dade College’s Building Construction Technology program before spending the better part of two decades measuring, fitting, and installing windows and doors across South Florida. She and her crew have served the Clewiston area for years, including work on homes near the U.S. Sugar Corporation corridor where the humidity and wind load demands leave no margin for a sloppy seal. She is known for pulling a frame twice before letting a bad measurement get buried behind trim. Measure it right the first time. Everything after that is just paperwork.
