ES Windows Energy-Efficient Windows in Naples: What to Know First
Independent ES Windows service work in Naples typically runs $185 to $640 per window depending on whether we’re replacing glass, rebuilding a sash, or addressing a failed seal that’s fogged the unit. Most energy-efficiency repairs on ES Windows frames take a single visit, and we quote the job in writing before any work begins. If you own ES Windows and the glass is fogged, the sash is binding, or your cooling bill has crept up in a home that used to hold its temperature, this page covers what actually goes wrong and what it costs to fix. Call (239) 326-9942 and a live person answers, day or night.

This page is for Naples homeowners who have ES Windows installed and want them working the way they were supposed to from day one. Dale Kessler and our crews have worked these frames throughout Collier County long enough to know their habits.
How ES Windows Products Fail - and How We Fix Them
- Failed seals on ES Windows insulated glass units. ES Windows builds a lot of dual-pane Low-E units destined for coastal Florida. The desiccant-filled spacer between the panes eventually saturates in humid air, and once it does, moisture shows up as permanent fog between the glass. We see this on older ES Windows double-hung and casement lines in Naples regularly. The fix is a new insulated glass unit matched to the original Low-E coating and gas fill, not a seal patch that fails again next season. Our glass shop orders the replacement IG unit to the exact thickness and spacer profile, so the sash closes true and the warranty on the new glass is registered in writing.
- Argon gas loss and declining thermal performance. Many ES Windows energy-efficient models ship with argon between the panes to boost insulation. Over a decade or more in Naples heat, that gas escapes slowly through worn edge seals. The window doesn’t necessarily fog, but it stops performing. Owners notice rooms on the west side of the house getting warmer in the afternoon than they used to. We confirm the loss with a thermal inspection and replace the glass with a properly filled unit rather than letting the homeowner chase the problem with heavier curtains and a bigger AC bill.
- Sticking or dragging sashes on ES Windows sliders and double-hungs. Salt air and fine sand from Naples beaches work into the tracks and rollers on ES Windows sliding lines. What starts as a stiff glide becomes a sash that won’t seal fully at the meeting rail, and a window that doesn’t seal is an energy leak the same as a broken pane. We remove the sash, clean and re-lubricate the hardware, replace worn rollers where needed, and set the interlock so the two sashes meet flush. If the frame has shifted out of square from settling, we correct the alignment so the window closes against the weatherstrip the way it was designed to.
- UV damage and fading on ES Windows interior films and glazing. Naples sun exposure is relentless. We’ve replaced a fair number of ES Windows units where the laminated or tinted interlayer has begun to haze or discolor after years of direct southern exposure, particularly on second-floor elevations with no overhang. Homeowners notice muted views and less visible light transmission. The remedy is a matched replacement glass specification, often with an upgraded UV-blocking Low-E coating that reduces interior fading on floors and furniture without darkening the room noticeably.
- Warped or compromised weatherstripping on older ES Windows lines. Energy efficiency dies a quiet death at the weatherstrip. Older ES Windows frames used compression gaskets that harden and take a set in Florida heat, leaving air gaps at the jambs and sills. We re-gasket the sash and frame using a profile matched to the original extrusion, which restores the air seal and knocks down the drafts that drive up conditioning costs in January and July alike. It’s a smaller job on the invoice, but it matters more than most people expect.
Our ES Windows Energy-Efficient Windows Process
- 1
Call and book. You call (239) 326-9942 and speak to a person, not a recording. We set a time and our technician arrives in uniform, background-checked, and on schedule.
- 2
Measure and diagnose. Every opening gets measured twice. We check the glass, frame, weatherstripping, hardware, and the square of the rough opening before we recommend anything. If the issue is a failed seal, we confirm it with a moisture read between the panes.
- 3
Written quote, side by side. We price the job on paper before work begins. If replacement glass is involved, we show you the OEM option and the quality aftermarket equivalent, with the differences in coating, gas fill, and warranty stated plainly.
- 4
The work. We remove the old unit or hardware, prep the opening, and install the replacement so the pane sits true in the frame. No shortcuts on shims, no reused sealant that’s already given up.
- 5
Test and verify. We cycle the sash, check the interlock, inspect the seal, and run a quick thermal check where the job calls for it. If it is not right when we leave, we come back until it is.
- 6
Guarantee in writing. Before the truck leaves the driveway, both warranty layers on the new glass are registered, durations stated, and the 90-Day Done Right Promise is yours. No paperwork fights later.
