ES Windows Window Replacement: The Three Lakes Owner’s Guide

ES Windows window replacement in Three Lakes typically runs $340-$780 per opening installed, depending on series, glazing, and whether the frame needs reworking. We stock ES Windows-compatible hardware and glazing assemblies on our trucks, and most replacements in Three Lakes can be surveyed and quoted same-day with installation scheduled within 48 hours. Most owners discover the problem when a window that once closed flush now sits proud of the frame, or when condensation appears between panes of a unit that was sealed tight five years ago.

Which ES Windows Models This Applies To

ES Windows manufactures three residential lines you’re likely to find in Three Lakes: the ES 100 Series (single-hung and horizontal roller), the ES 2000 Series (impact-rated single-hung and fixed), and the ES 5000 Series (thermally broken, impact-rated). The label is stamped on the top rail of the sash or etched into the spacer bar between glass panes; it includes a six-digit manufacturing date code and the series prefix. We need that code to match hardware - the ES 2000 and ES 5000 use different roller assemblies and keepers, and swapping them causes binding within a month.

For glazing replacement, ES Windows uses a proprietary glazing bead profile on impact-rated units that interlocks with the frame wall thickness. Generic bead from a supply house won’t seat properly and voids any remaining warranty. We source OEM glazing packages or certified equivalents that match the original NOA (Notice of Acceptance) submission. On units installed 2015-2019, we’ve found the original spacer bar was a stainless steel box design prone to seal failure in South Florida’s UV load; current ES Windows units use a warm-edge spacer we specify as replacement.

Signs Your ES Windows Window Replacement Is Failing

• Condensation between glass panes. The insulated glass unit (IGU) seal has failed, allowing moist air into the airspace. In Three Lakes, this accelerates when afternoon sun hits east-facing units after morning rain, cycling the IGU through rapid temperature swings.
• Sash won’t stay open or slams shut. The balance system - coil spring or block-and-tackle, depending on ES series - has lost tension. ES 100 Series units from 2016-2018 shipped with a balance shoe that cracks at the pivot pin; we stock the updated shoe and pin assembly.
• Rolling window sticks or jumps the track. The roller assembly has flat-spotted or the axle has corroded. Three Lakes homes near the Killian Corridor catch more road grit than inland properties, and we’ve found rollers packed with fine dust that acts like grinding compound.
• Frame corner gaps or visible daylight. The sash or frame has shifted due to settlement, or the interlock weatherstrip has compressed permanently. This is structural - shimming the sash without checking the frame plumb makes it worse.
• Cracked impact glass with intact laminate. The outer lite has fractured but the inner laminate holds. This still compromises the impact rating; the NOA requires both lites intact to meet the design pressure rating for Miami-Dade.

Replacement Cost & What’s Included

What drives the range: unit size, floor level (second-story carries ladder/setup time), and whether the rough opening has settled out of square. Every quote we write in Three Lakes starts with a measured survey you keep - frame width, height, and diagonals recorded to the sixteenth - and the price on that document matches the final invoice. Haven Clause 1: have it in writing. Labor, disposal of the old unit, and a one-year workmanship warranty are included; the 365-Day Done Right Promise covers anything that doesn’t perform as specified.

DIY or Call Us?

There’s a short list of what an owner can safely verify: check the label for series and date code, photograph any cracks for our review, and confirm the window is unlocked before assuming it’s broken. Beyond that, ES Windows impact-rated units are heavy - a 36-by-72 double-hung can exceed 80 pounds - and the glazing is under constant pressure from the frame’s interlock design. Removing a sash without supporting the frame risks corner joint separation.

We don’t recommend homeowner disassembly of the balance system. The coil springs in ES 100 Series units store enough tension to cause hand or facial injury if released uncontrolled. Our technicians carry the winding tools and bracket jigs specific to each ES series. For a no-charge assessment in Three Lakes, call (786) 808-5792 - we’ll measure, photograph, and hand you a written scope before any work is scheduled.
