ES Windows Window Replacement: The Miami Owner’s Guide

Replacing a failed ES Windows unit in Miami typically runs between $900 and $2,400 installed, depending on the series, glass package, and whether the frame can be salvaged or the whole unit has to come out. We stock ES Windows-compatible replacement sashes, glass packages, balances, rollers, and hardware, and we can match most ES Windows models within a day after we measure. Most homeowners discover the problem the hard way: a window that suddenly won’t stay up, condensation fog trapped between the panes, or a crank that spins without moving the sash.

If you’re in Miami and an ES Windows unit has failed on you, here’s what you need to know before you spend a dollar. Ed Winslow has been replacing and matching ES Windows parts in South Florida for over a decade, and the honest answer is this: some failures are a simple hardware swap, and some mean the sealed unit is done. We’ll tell you which one you have before we ever write an estimate.

Which ES Windows Models This Applies To

ES Windows builds several distinct product families, and the replacement path depends on which one you’re dealing with. The biggest compatibility gotcha we see in Miami: single-hung and horizontal roller models from the ES Windows builder-grade series use different balance systems than their higher-end casement and awning lines. You can’t interchange them, and if a handyman tries, the window will never operate correctly again.

We work on and source parts for the full ES Windows lineup: single-hung, double-hung, horizontal rollers, casements, awnings, and fixed picture windows. The fastest way to identify yours is on the label etch in the corner of the glass or along the frame edge. There’s a series code and sometimes a manufacturing date. If that label is faded or painted over, we fall back to measuring the visible glass dimensions and the frame depth, then matching hardware by profile.

The OEM-versus-aftermarket question comes up a lot. For ES Windows, we use OEM components whenever they’re still available because the track geometry and balance seat tolerances are tight. For older discontinued series, we use aftermarket equivalents we’ve tested on Miami jobs for years. Both options carry our workmanship warranty, and we’ll show you exactly what we’re putting in before we install it.

Signs Your ES Windows Window Replacement Is Failing

• Fog or condensation between the glass panes. The sealed unit’s inert gas has leaked out and moisture has taken its place. It won’t dry out on its own, and the window’s energy performance is already shot. This is the most common ES Windows failure we replace in Miami’s humidity.
• Sash drops or won’t stay open. A balance or pivot shoe has worn out, or in some ES Windows single-hungs, a spring in the block-and-tackle assembly has snapped. This is a safety issue, not just an annoyance, especially for second-story windows.
• Hardware spins, sticks, or breaks. Casement cranks and awning operators strip gears over time, particularly with salt air exposure in neighborhoods like Coral Gables and Coconut Grove. Replacement operators are regularly on our trucks.
• Water stains or soft framing around the sill. The glazing gasket or the weather seal has failed, letting water sit against the frame. In Miami’s wet season, that rots a wood interior frame fast and can breed mold before you notice the stain.
• Drafts or outside noise you didn’t hear before. Gaskets have compressed or the frame has shifted. It means the seal is gone, and with it, the energy rating you paid for.

Replacement Cost & What’s Included

In Miami, here’s what we currently see on ES Windows replacement work:

• Sealed glass unit replacement: $400–$850 per unit, installed
• Balance or roller hardware replacement: $180–$380 per sash, installed
• Full sash replacement (glass, frame, hardware): $700–$1,400 per window, installed
• Complete window replacement (tear-out and new unit): $1,100–$2,400 per opening, installed

The price spread comes down to size, series, and glass type. An impact-rated laminated glass package costs more than standard insulated glass, and it should. We quote parts and labor separately so you can see exactly what you’re paying for, and the quote we give you is the number on the invoice. No surprise change orders. Every replacement carries our workmanship warranty, and as an independent service provider, we’re not tied to any factory’s script. If something’s not right, Ed Winslow’s name is on it, and we come back.

DIY or Call Us?

There are two safe checks you can do yourself. First, read the corner label on the glass so you know your series code. Second, check the track and rollers for debris, because Miami’s grit builds up fast. Cleaning the track is about the limit of what we’d recommend.

Here’s the hard truth: replacing a sealed ES Windows glass unit or a tensioned balance system is not a weekend project. Balances are under load, and a slip can mean broken glass, a damaged frame, or worse. We’ve also seen DIY glass swaps where the new unit was shimmed slightly off-square, and within months the frame bowed and the seals failed again. By the time the homeowner called us, they’d paid twice for the same repair. If you’re anywhere in Miami, call (844) 901-4551. We’ll identify what failed, quote it straight, and schedule the fix.
