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.

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.

PGT Window Installation: The Clewiston Owner’s Guide
PGT window installation in Clewiston typically runs $340-$780 per opening depending on the series, size, and whether the wall needs structural prep for impact-rated glazing. We stock PGT-compatible hardware, fasteners, and flashing systems for same-day starts on most Winguard and WinVue series, and we carry CGI and CWS backup lines when a custom PGT order runs long. Most Clewiston homeowners notice a problem when the sash won’t stay open, the lock tongue misses the keeper, or they feel air movement around a frame that used to seal tight against afternoon thunderstorms rolling off Lake Okeechobee.
Which PGT Models This Applies To

PGT stamps its series code on the spacer bar between the glass panes, visible when you open the sash and angle the glass toward the light. Winguard aluminum and vinyl lines, WinVue single-hung and horizontal roller, and the older Architectural Series all share common installation hardware, though the clip spacing and sill angle vary by frame depth.
The gotcha we see most in Clewiston: a homeowner orders replacement hardware for a Winguard vinyl window but receives parts meant for the aluminum extrusion. The vinyl frame uses a narrower jamb clip, roughly 1-3/16″ center-to-center, where aluminum runs 1-5/16″. Mix those up and the sash racks in the opening, chewing the weatherstrip. We verify the series code against PGT’s current spec sheet before any part leaves our truck.
We are an independent service provider, not affiliated with PGT. For most repairs we use PGT OEM hardware; for discontinued series we source from CWS and ES Windows equivalents that match the load rating and finish. The customer gets the part number in writing either way.
Before
AfterSigns Your PGT Window Installation Is Failing
- Sash drops or won’t stay open. The balance shoe or coil spring has lost tension. In Clewiston’s humidity, the pivot bar rusts where it meets the shoe, and the shoe itself cracks from UV cycling through the screen track. We replace both as a matched set; swapping one and not the other guarantees a callback.
- Lock tongue won’t engage the keeper. The sash has sagged on its hinges or the frame has settled. We check plumb with a 4-foot level before blaming the lock. Often the fix is shimming the hinge side, not replacing the lock at all.
- Visible daylight or air movement at the frame perimeter. The installation flange has pulled from the buck, or the backer rod and sealant have shrunk. This is where Clewiston’s afternoon heat and driving rain punish a sloppy seal. We pull trim, document the gap with photos, and reflash before the water finds the sheathing.
- Condensation between glass panes. The insulating glass unit (IGU) has lost its seal. PGT’s warranty covers the glass; our scope is removing the sash, coordinating the IGU replacement, and reinstalling to the original sightline measurement so the reveal stays even.
- Cracked or chalking exterior frame. Vinyl oxidation accelerates on south and west exposures in Hendry County. The frame is still structurally sound, but the installation clips become brittle. We replace clips and add a drip cap if the original installer omitted one.
Replacement Cost & What’s Included

| Scope | Typical Range in Clewiston |
|---|---|
| Hardware-only swap (balance, lock, keeper) | $180-$290 |
| Sash removal, IGU replacement, reinstall | $340-$520 |
| Full opening: remove old window, install new PGT unit, flash, trim | $580-$780 |
| Structural prep for impact-rated upgrade (buck repair, header check) | $180-$340 additional |
What drives the range: frame condition behind the trim, whether the original installation used pan flashing or just caulk, and whether the opening is on a second story requiring scaffolding. Every quote we write in Clewiston starts with the measured survey the customer keeps. The price on that document matches the final invoice. Haven Clause 1: have it in writing. Haven Clause 5: no surprises.
Our 365-Day Done Right Promise covers the installation labor and any hardware we supply. The PGT glass warranty runs 10 years on IGUs; we handle the claim paperwork and coordinate the replacement.
DIY or Call Us?
There’s no high-tension spring or electrical hazard in a typical PGT window, but there is a precision hazard. A homeowner can safely check whether the lock keeper has loosened from the frame, or whether debris is blocking the weep holes at the sill. A vacuum and a screwdriver handle those.
Where DIY goes wrong: forcing a sash out of its track without releasing the balance tension first, which bends the pivot bar and converts a $45 part into a full sash replacement. Or using silicone caulk where PGT specifies butyl tape at the head flange, which traps moisture against the buck. And measuring the rough opening from drywall face to drywall face instead of from the structural buck, which orders a window that fits the hole but not the wall.
Measure it right the first time. Everything after that is just paperwork. Sonia Raman pulls a frame twice before she lets a bad measurement get buried behind trim. Call (863) 509-1135 and we’ll schedule a free estimate with the measured survey you keep.
FAQs

A properly installed PGT impact window should perform 20-25 years in Clewiston, though the IGU seal averages 12-15 years before fogging appears. The hardware, tested to 10,000 cycles, usually fails from corrosion first, not wear. Call (863) 509-1135 for an exact quote on your series and vintage - estimates are free.
Hardware failures, balance issues, and IGU seal breaches are all repairable without removing the frame from the opening. We only recommend full reinstallation when the frame has settled out of square, the buck is rotted, or you’re upgrading to impact-rated from non-impact. Call (863) 509-1135 and we’ll tell you which category you’re in.
A hardware replacement takes 45-90 minutes per window. A full removal and reinstall runs 3-5 hours per opening, longer if we find structural repair behind the trim. We schedule one opening per day for full replacements so we don’t rush the flashing cure. Call (863) 509-1135 to check availability.
We stock balance assemblies, lock sets, keepers, and weatherstrip for Winguard and WinVue series on our Clewiston service truck. Custom-color hardware and discontinued series parts order in 5-10 business days; we carry CGI and CWS equivalents as backup when timing matters. Call (863) 509-1135 to confirm stock for your series code.
