As an independent ES Windows service provider, we’re not the manufacturer. That means we have no interest in selling you a new window when a seal repair or glass replacement fixes the problem for a fraction of the cost. We also carry quality aftermarket glass packages that meet or exceed ES Windows specs, so you’re never locked into factory pricing.

How ES Windows Products Fail - and How We Fix Them

ES Windows builds a solid aluminum frame, but the energy-efficient performance lives in the glass package. When that package fails, the window stops doing its job. Here’s what we see most often in Westchester:

• Fogging on ES Windows 7000 Series. This is the workhorse line in Westchester homes, and the biggest complaint we hear is condensation between panes. The cause is almost always a failed butyl seal around the insulated glass unit (IGU), which lets humid Florida air inside the gap. The fix is IGU replacement, not the whole window. We measure, order, and install a new argon-filled unit, then reseal with the OEM spec.
• ES Windows 7100 Series Low-E coating degradation. In south-facing rooms, we see the Low-E film start to craze or haze after 10 to 15 years of direct sun. That haze isn’t cleanable - it’s the coating breaking down. Homeowners sometimes think the glass is just dirty, but running a razor blade across it does nothing. We can replace the glass with an upgraded Low-E package that handles South Florida UV better than the original.
• Drafty operation on ES Windows 5000 Series sliders. When the wool pile weatherstripping compresses flat, the window loses its thermal edge. You’ll feel heat radiating in around the meeting rail on hot Westchester afternoons. We replace the pile with a higher-density option and realign the rollers so the window seats tight against the frame.
• Fading floors and furniture from single-pane ES Windows. Many older Westchester homes still have single-pane ES Windows from the 1990s. The glass is structurally fine but thermally useless. Rather than tear out frames, we can often fit the existing openings with a double-pane, Low-E insulated unit - UV blocking jumps from near zero to 95% or better, and the frame stays original.
• Argon gas loss on any ES Windows IGU. Even if the window looks fine, the gas between panes leaks out over decades of thermal cycling. You won’t see fogging until the seal fully fails, but the window’s energy performance has already dropped. When we replace an IGU, we pressure-test the new unit before install and verify the gas fill matches the original spec.

Our ES Windows Energy-Efficient Windows Process

Every ES Windows job follows the same six-step process, whether it’s a single seal repair or a whole-home glass package. This is how we’ve handled ES Windows work in Westchester since 2011, and it’s what keeps our rework rate near zero.

1. 1
   Call and talk to a person. You call (850) 721-1218. Ed or a member of the team answers. We ask about the symptoms, get your address, and schedule a window we can keep. No voicemail loop.
2. 2
   On-site diagnostic. Our tech arrives in a uniform, walks the windows, and checks the glass package, seals, frames, and room orientation. We tell you what’s actually wrong - not what a salesman would prefer to sell.
3. 3
   Straightforward quote. You get a written line-item estimate in plain English. It lists the glass type, the gas fill, the seal spec, and the exact labor. No “we’ll see once we start.”
4. 4
   Parts decision. We present two options when they exist: OEM ES Windows parts where warranty and resale matter, or a quality aftermarket IGU that performs identically for less money. You decide. We never upsell.
5. 5
   Repair or replacement. Our techs do the work cleanly, remove the old IGU without damaging frame finish, install the new unit with OEM-spec glazing, and reset all weatherstripping. If we’re replacing full windows, we pull the old frame and flash the opening properly for South Florida water management.
6. 6
   Test and walkthrough. We check the seal, run the window through its full travel, inspect from inside and out, and clean up the workspace. Then we walk the job with you so you can see and feel the difference before we leave. Every job is backed by our Done Right Promise: if it’s not done right, we make it right.

What ES Windows Energy-Efficient Windows Costs in Westchester

Here’s what we charge for common ES Windows jobs in Westchester. These are real numbers from our local jobs, not manufacturer list prices.

• IGU replacement (seal repair, argon fill): $180 to $340 per window, depending on size and whether we’re matching OEM glass or upgrading to a better Low-E package.
• Whole-window replacement with ES Windows 7000 Series: $850 to $1,400 per opening, installed, including frame, glass, and flashing. The range reflects window size and whether you’re going single-hung or picture.
• Full-home glass package (10+ windows): $8,500 to $16,000, depending on glass type, window count, and whether we’re keeping existing frames or replacing everything.

The biggest cost driver is glass package, not labor. A basic Low-E double-pane costs less than a high-performance argon-filled, gas-tested unit with UV-blocking film. Size matters too - one large picture window can cost more than three standard sliders. We’ll give you an exact number before work starts. Call (850) 721-1218 for a free estimate.

Why Westchester Homeowners Call Winslow Windows & Doors for ES Windows Work

Westchester isn’t a zip code to us. Ed Winslow grew up here, not far from Tropical Park, and the company has been installing ES Windows and other premium brands in the neighborhood since 2011. When you call, you’re calling a local business with a published address and license number - not a franchise with a rotating crew of subcontractors. Ed’s name is on the door, and on every estimate we hand out.

We’re also not a one-brand shop. Along with ES Windows, we install and service PGT, CGI, CWS, and ECO Window Systems. That matters because it means we’ll tell you honestly when a different glass package gives you better value. If you ever need an impact-rated window instead of a standard energy-efficient unit, we’re already authorized for those lines and can switch without sending you to another company. We answer the phone 24/7. Every technician is background-checked and uniformed.
