ES Windows Window Replacement: The Boca Raton Owner’s Guide

ES Windows window replacement in Boca Raton typically runs $340-$780 per opening installed, depending on the series and whether the frame is salvageable. We stock ES Windows-compatible sashes, balances, and hardware for same-day replacement on most residential models found in Boca Raton homes built between 2005 and 2020. Most owners discover the failure when a window won’t stay open, won’t lock, or shows visible moisture between the glass panes after a storm.

Which ES Windows Models This Applies To

ES Windows manufactures three residential series you’re likely to find in Boca Raton: the ES 100 (single-hung and horizontal roller), the ES 2000 (impact-rated single-hung and fixed), and the ES 4000 (thermally broken impact series common in newer construction west of Military Trail). The label is usually etched into the glass corner or stamped on the frame edge; if it’s worn off, we measure the sash thickness, check the balance shoe width (9/16-inch on ES 100, 3/4-inch on ES 2000/4000), and match the glazing bead profile.

We are an independent service provider, not affiliated with ES Windows. For most Boca Raton replacements, we source OEM-spec parts through ES Windows’ Florida distribution network. On discontinued series, we fabricate compatible sashes to the original U-factor and SHGC (solar heat gain coefficient) ratings rather than forcing a full-frame replacement. The ES 2000’s integrated lift rail is a known weak point; we’ve replaced enough of them in Palmetto Park and Boca Del Mar to keep the extrusion profile on file.

Signs Your ES Windows Window Replacement Is Failing

• The sash drops or won’t stay open. This usually means the coil balance has lost tension or the balance shoe is cracked. In Boca Raton’s salt air, the galvanized spring housing corrodes faster than inland specs predict, typically showing failure at 8-12 years rather than the 15-year rating.
• Visible fog or moisture between glass panes. The insulated glass unit (IGU) seal has failed. Once argon or air mixes with Florida humidity, the desiccant saturates and the view turns permanently milky. ES Windows IGUs from the 2010-2016 production window used a dual-seal system that held up well; earlier single-seal units are more prone to this.
• The lock won’t engage or the keeper is loose. Often the result of frame sag in the header, especially on ES 100 horizontal rollers wider than 48 inches. The cam lock itself is replaceable, but if the frame has settled, shimming the keeper is a temporary fix that hides a structural issue.
• Air infiltration at the meeting rail or frame perimeter. Compression weatherstrip hardens in UV exposure. ES Windows uses a fin-seal design that works until the vinyl fin takes a set; replacement requires the correct bead profile or the new seal won’t seat.
• Cracked or chipped impact glass with the laminate intact. The window still protects against windborne debris, but the crack creates a stress riser. Under the Florida Building Code, impact-rated assemblies must maintain their design pressure rating; a cracked lite compromises that even if the interlayer holds.

Replacement Cost & What’s Included

What drives the range: the series (ES 4000 thermal break costs more than ES 100), whether the frame is square within 1/8-inch (we measure before quoting), and whether the existing trim can be preserved. Every quote is the measured survey you keep; the written price before any work starts is Haven Clause 1. The 365-Day Done Right Promise covers the installation and the part. We pull permits when the replacement affects the impact rating or the opening size changes.

DIY or Call Us?

What you can safely check: verify the series from the glass label, confirm the symptom (does the sash fail at every position or only full extension?), and photograph the balance shoe or lock mechanism. What goes wrong fast: ES Windows sashes are heavier than they look, especially impact-rated units; a dropped sash can shatter the glass or damage the frame. The coil balance stores significant tension, and the wrong tool can release it unpredictably. We don’t recommend homeowner removal of any sash over 30 pounds or any unit above the first floor. If you’re unsure of the series or the frame measurements, call (561) 200-8592 and we’ll confirm what you’re looking at before you order the wrong part.
