How PGT Products Fail - and How We Fix Them

PGT builds a solid window, but Boca Raton’s salt air, afternoon sun, and hurricane-season humidity find every weak point. Here’s what we see most often on service calls across the city, from Broken Sound to the neighborhoods east of I-95.

• Fogging between panes on PGT WinGuard insulated units. The most common energy-efficiency killer. Over time, the perimeter seal on an insulated glass unit breaks down, letting moisture in. The window still keeps wind out, but the argon gas is gone and the Low-E coating starts to oxidize. The fix is replacing the glass unit itself - not the whole window - which restores the thermal barrier and the clarity.
• Worn or brittle weatherstripping on PGT SpectraGuard frames. The gaskets and sweeps that seal the sash against the frame dry out and harden in Boca Raton’s sun. Once they lose their elasticity, conditioned air leaks out and humid outdoor air sneaks in. We replace the stripping with a material matched to the frame profile, which usually costs far less than a new window and immediately tightens up the seal.
• Failed Low-E coating along the bottom edge of fixed PGT windows. In homes closer to the Intracoastal, we often see the Low-E layer break down first along the bottom quarter of the glass. The salt in the air accelerates the edge-seal corrosion. The symptom is a milky or bronze haze that never wipes clean. The real cause is a compromised seal, and the correct fix is a replacement IGU with a fresh Low-E stack - not a surface film.
• Soft spots or rot at the sill of older PGT aluminum frames in ground-floor condos. Many original PGT installs along Federal Highway and in Spanish River area buildings used aluminum frames with wood bucking underneath. After fifteen or twenty years of irrigation overspray and summer downpours, that wood rots. The window itself may be fine, but the energy performance is gone because air moves freely through the rotted sill. We pull the window, replace the bucking with pressure-treated material, and reset the unit with new flashing and sealant.
• Imbalance and sag on PGT double-hung sashes. Once a double-hung doesn’t close square, the top and bottom corners of the meeting rail start leaking air. The cause is usually worn or broken coil balances inside the side jambs. We rebuild the balance system, reset the sash, and test the seal with the sash closed and locked - because a window that doesn’t lock tightly is always an energy leak, even if you can’t feel a draft.

Our PGT Energy-Efficient Windows Process

Here’s how a typical PGT energy-efficiency job goes from first call to final walkthrough.

1. 1
   Call and describe what you’re seeing. Fogging, rooms that run warm, a draft you can feel at night. A live person answers, day or night. We’ll ask the right questions and get your address.
2. 2
   We inspect the window or windows in person. Every tech who shows up is background-checked and in uniform. We check the seal integrity, the frame, the operation, and the thermal performance. You get a written line-item quote before any work starts - no vague verbal ballparks.
3. 3
   We decide on the parts path. For glass replacement, we discuss OEM-equivalent IGU options and whether a quality aftermarket unit makes more sense for your budget. For hardware and sealing parts, we explain what’s worth matching to the original and what’s ready for an upgrade.
4. 4
   The work gets done. We protect the floors, remove the old glass or hardware carefully, and install the new components with sealant and flashing that’s rated for South Florida exposure.
5. 5
   Testing. We check for air movement around the frame, operate the sash multiple times, and confirm the glass is seated correctly. You’ll see the difference in the room almost immediately.
6. 6
   Cleanup and the Done Right Promise. We haul off the old glass and packaging and leave the work area cleaner than we found it. And every job carries the 36500-Day Done Right Promise - if it’s not done right, we make it right.
