ES Windows Energy-Efficient Windows in Fort Lauderdale: What to Know First
ES Windows energy-efficient windows in Fort Lauderdale can be repaired or replaced by our team at Winslow Windows & Doors, typically within 3 to 7 business days once parts are sourced. We’re an independent ES Windows service provider - not the manufacturer - which means we give it to you straight on whether your window needs a seal repair, glass replacement, or a full swap. Most energy-efficiency repairs on ES Windows units run between $95 and $475 depending on the glass pack and frame condition. If you own ES Windows and your electric bill has crept up, call (904) 747-8989 and Ed Winslow or one of our techs will walk you through what’s actually going on.
This page is for Fort Lauderdale homeowners who already have ES Windows installed and need them working like they should - keeping heat out, cool air in, and UV rays off your furniture. We’ll cover failure points, real costs, and what a proper fix looks like.
How ES Windows Products Fail - and How We Fix Them
We’ve been servicing ES Windows across Fort Lauderdale long enough to know their patterns. Here are the five issues we see most often on the energy-efficiency side, and exactly what we do about each one.
- Fogging between panes on the ES Windows 7400 series. This is the big one. The 7400 insulated glass units (IGUs) use a warm-edge spacer and argon fill, and when the edge seal degrades in Fort Lauderdale’s humidity, the argon leaks out and moisture gets pulled in. You’ll see a hazy film that won’t wipe off because it’s inside the sealed unit. The fix is replacing the IGU glass pack, not the whole frame. We source exact-fit replacement glass that matches the original low-E coating and argon specification, so the window’s energy performance comes back to spec. If you just live with the fog, that window becomes a thermal hole.
- Failed low-E coating on ES Windows 9000 series units facing south or west. Low-E coatings on the 9000 series are good, but years of direct Fort Lauderdale sun exposure plus salt air can cause the coating to oxidize, especially near the frame edges. You’ll notice a cloudy or blotchy appearance in the glass itself, not between panes. That window is still physically intact, but it’s letting in more solar heat than it should. We replace the glass pack with a current low-E variant matched to the original Solar Heat Gain Coefficient, which restores the UV-blocking and fade protection your A/C was relying on.
- Condensation on the interior frame of ES Windows 400 series in older Fort Lauderdale homes. The 400 series is a popular retrofit line, but in homes from the 1970s and 80s around neighborhoods like Sailboat Bend and Rio Vista, we regularly find the original install had insufficient perimeter insulation around the frame. Humid air hits the aluminum frame, condenses, and drips onto the sill. That’s not a window failure from ES Windows - it’s an installation gap. We pull the interior trim, re-insulate the rough opening with closed-cell foam, and re-seal both the interior and exterior perimeter. The window itself stays; the leak path goes away.
- Stiff or loose operation causing you to leave windows open in “shoulder season” - then the A/C runs anyway. If an ES Windows slider or casement doesn’t close cleanly, homeowners in Fort Lauderdale tend to leave it cracked for air. That defeats the whole purpose of an energy-efficient window. On ES Windows casements, we usually find the crank mechanism has worn gears or the operator arm is misaligned. On sliders, the brass roller assemblies in the bottom track flatten out over time. We replace the hardware with quality aftermarket components spec’d to the original ES Windows dimensions, then re-lubricate the track and realign the sash so it seats squarely against the weatherstripping. Once it closes tight, the seal does its job.
- Worn weatherstripping on ES Windows 700 series horizontal rolling units. Fort Lauderdale’s heat and humidity are hard on flexible seals. After five to seven years, the wool pile and vinyl bulb gaskets on the 700 series compress and lose their rebound. You’ll feel a draft around the sash edges on hot days. We replace the weatherstripping with OEM-spec material - not generic foam tape - so the air-infiltration rating returns to the original test values. It’s a $60 to $120 fix per window that often pays for itself within a couple of A/C billing cycles.
Our ES Windows Energy-Efficient Windows Process
When you call us about an ES Windows unit that isn’t performing, here’s how the job actually goes - no mystery, no change orders.
- 1
Call and talk to a person. You reach a live person at (904) 747-8989, day or night. We ask what you’re seeing: fogging, draft, condensation, high bills. We also ask which direction the window faces and roughly how old the unit is.
- 2
On-site diagnostic. We come out, inspect the glass pack, frame, weatherstripping, and the rough opening. We use a moisture meter and a simple draft test to confirm where the energy leak is. The diagnosis is free with any repair we perform.
- 3
Honest recommendation. If the window can be saved with a glass pack or hardware replacement, that’s what we recommend. If the frame is compromised or the unit is past its useful life, we’ll tell you that too - and we’ll show you the numbers for both options. We install replacement ES Windows when it makes sense, and we’re also authorized for PGT, CGI, CWS, and ECO Window Systems if a different window is the better call for your home.
- 4
Parts decision together. We walk you through OEM versus quality aftermarket for your specific ES Windows model. For glass packs, we always match the original spec. For hardware, we’ll tell you when aftermarket is actually the better value and when OEM is non-negotiable. You decide with the full picture in front of you.
- 5
Installation and testing. We handle the repair or replacement, then test the window for air infiltration, proper seating, and smooth operation. We don’t call it done until it passes.
- 6
Cleanup and the Promise. We leave the work area clean, walk you through what we did, and you’re covered by the 36500-Day Done Right Promise: if it’s not done right, we make it right.

FAQs
Yes. In most foggy ES Windows units, only the insulated glass pack needs replacing, not the entire frame. The frame and hardware usually stay in place, and we install a new IGU matched to the original low-E coating and argon gas specification. Call (904) 747-8989 with your window’s glass size and we’ll quote the glass pack replacement.
It depends on the work performed and the warranty period left on your unit. We follow warranty-safe practices on every ES Windows job, including matching original glass specifications and using non-invasive frame procedures when required. As an independent ES Windows service provider, we can’t speak for the manufacturer’s warranty department, but our 36500-Day Done Right Promise covers our work regardless.
Stand next to the window at day’s peak heat and hold your hand six inches from the glass. If you feel radiant heat, the low-E coating has likely degraded. If you feel air moving around the sash edges, your weatherstripping has failed. Fog between panes means the gas fill is gone. We offer window energy audits that check all three on every unit and give you a rating per window so you can prioritize repairs.
Repair makes sense when the frame is sound and only the glass pack, hardware, or weatherstripping has failed. Replacement makes sense when the frame is corroded, bent, or leaking structurally. We quote both options on jobs where it’s a close call, so you decide with real numbers.
Most repairs are completed in 3 to 7 business days once parts arrive. Simple hardware and weatherstripping jobs are sometimes faster. Call (904) 747-8989 for a same-week diagnostic and we’ll give you a real timeline for your specific windows.
