How ES Windows Products Fail - and How We Fix Them
ES Windows builds a solid aluminum frame, but Fort Myers heat and humidity expose weaknesses over time. Here’s what we see most often on ES Windows units in Lee County homes:
- Seal failure in the ES700 series. The insulated glass unit (IGU) loses its seal, letting argon gas escape and moisture creep in. You’ll notice fogging between the panes or condensation that won’t wipe away. We replace the IGU with fresh Low-E argon-filled glass and the window performs like new.
- Weeping system clogs on ES600 sliders. ES sliders use weep holes to drain water, and Fort Myers’s combination of oak pollen and fine sand clogs them fast. Water pools in the track, then seeps toward the interior. We clear the weep channels, check the drainage slope, and reseal where needed.
- Fading UV protection on older single-pane units. Homes with original ES Windows from the 1990s often have single-pane glass with the UV film long since degraded. Furniture and flooring fade noticeably. We upgrade to insulated laminated glass that blocks the majority of UV rays without changing the frame.
- Warped sashes on west-facing installations. Fort Myers afternoon sun beats on west-facing windows for hours. On certain ES Windows casement units, the aluminum sash can warp just enough to break the weatherstripping seal, letting conditioned air escape. We inspect, re-align, and replace damaged weatherstripping before recommending full replacement.
- Condensation between panes on second-story units. This is a recurring issue we find in Fort Myers communities like McGregor Boulevard’s older homes and newer builds near the Caloosahatchee. The elevated exposure to morning humidity accelerates seal degradation. We replace the IGU and verify the frame is still square enough to hold a proper seal for years.
Our ES Windows Energy-Efficient Windows Process
Here’s how a typical ES Windows energy-efficient job goes when you call Winslow Windows & Doors:
- 1
You call (239) 453-7751. A live person answers. We ask what you’re seeing: fogging, drafts, heat gain, condensation. We schedule a time that works for you, with no trip charge inside Lee County.
- 2
We inspect every window, not just the problem one. ES Windows units are often installed in banks of three or four, and when one seal fails, its neighbors usually aren’t far behind. We check each IGU, frame condition, and weatherstripping.
- 3
We give you a written, line-item estimate. You’ll see exactly what we recommend, what parts we’ll use, and what it costs. No vague language, no surprises on the invoice.
- 4
We source the right glass. For ES Windows repairs, we weigh OEM glass against quality aftermarket options and tell you honestly which makes sense for your situation. On older units outside warranty, aftermarket Low-E argon-filled IGUs often deliver better energy performance per dollar.
- 5
We install, test, and verify. We replace the IGU or the full unit, check for air leaks around the frame, and confirm the window operates smoothly. We clean up completely before we leave.
- 6
We stand behind it with the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. That’s Ed’s word, and it’s been the backbone of this company since 2011.

FAQs
In most Fort Myers homes, yes, you can replace just the insulated glass unit without replacing the entire ES Windows frame. IGU replacement typically costs $350-$650 per window and restores energy performance when the frame is still square and functional. We’ll tell you honestly if your frame has degraded to the point where full replacement makes more financial sense. Call (239) 453-7751 for a free assessment, and remember the free second opinion on any written estimate you already have.
For ES Windows units still under the manufacturer’s warranty, the safest path is OEM glass through an authorized channel. As an independent ES Windows service provider, we’re transparent about what we can and cannot do warranty-wise. For units outside warranty, quality aftermarket IGUs often deliver equal or better energy performance at a lower cost. We walk you through the trade-offs before you spend a dime.
Most IGU replacements on ES Windows units in Fort Myers are completed in a single visit, usually within two to three hours for one or two windows. If we’re replacing multiple windows, we typically schedule a full day. Glass lead times can add a few days, but we’ll give you a firm timeline upfront.
Yes, and the difference is measurable. Fort Myers homes with single-pane or failed-seal ES Windows see the biggest jump in cooling costs from May through October. Switching to Low-E argon-filled insulated glass reduces solar heat gain and keeps conditioned air inside. Many homeowners report noticeable drops in their FPL bills within the first full summer after replacement.
Yes, and it’s permanent, not a limited-time promotion. Seniors and veterans get 10% off every job, every time. We also offer $40 off any repair over $200 and no trip charge inside Lee County. Call (239) 453-7751 and mention your status when you schedule.
