ES Windows Window Replacement: The Weston Owner’s Guide

ES Windows window replacement in Weston typically runs $340 to $780 per opening for standard vinyl and aluminum units, with impact-rated ES Windows Series 9000 and 10000 models landing higher due to laminated glass and reinforced frame requirements. We stock common ES Windows sash, balances, and hardware on our Weston trucks, and most replacements measured before noon are installed within 48 hours. The failure usually announces itself on a humid August morning: the sash won’t stay up, or you notice the glazing bead has pulled away from the frame after a storm passed through the Bonaventure area.

Which ES Windows Models This Applies To

ES Windows manufactures across four distinct series that you’ll find in Weston homes built from 2005 onward, and the replacement part you need depends entirely on which badge is stamped into the frame rail.

The Series 3000 is the non-impact vinyl line common in interior rooms and second stories; its sash balances are 5/8-inch tilt-type and cross-compatible with several aftermarket suppliers. The Series 5000 aluminum line, popular in Weston Hills and Country Isles installations from the 2010s, uses a proprietary interlock design that demands OEM-grade replacement or the weatherseal will not seat correctly. The Series 9000 and 10000 impact-rated units are where we see the most call volume in Weston; these use laminated glass minimum 9/16-inch thick and reinforced sash locks that fail under cyclic wind load if a previous installer substituted generic hardware.

To identify your unit: open the sash and photograph the etched code on the glass corner, then check the frame edge for a stamped series number. The Series 5000 interlock is a 1.25-inch stack height; generic 1-inch interlocks will gap and whistle. We carry both OEM ES Windows hardware and verified equivalents rated to the same Miami-Dade HVHZ specifications, and we note the source on your written quote before ordering.

Signs Your ES Windows Window Replacement Is Failing

• The sash drops or won’t stay open. This is almost always a failed coil balance or broken pivot bar in ES Windows tilt-wash units. In Weston, the salt air accelerates corrosion in the balance shoe, so a sash that held fine in March may fail entirely by September.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has breached. On south-facing ES Windows installations in Weston, thermal cycling from afternoon sun to evening rain breaks the butyl seal faster than manufacturer estimates predict; the glass pack needs replacement, not defogging.
• Frame corner separation or warping. Aluminum Series 5000 frames in Weston homes near the Everglades edge often show this first at the sill corner where condensation pools; vinyl Series 3000 frames warp when the interior reinforcement channel corrodes from trapped humidity.
• Lock hardware spins freely or catches. The cam lock has stripped its zinc housing. ES Windows used two different cam depths across production years; the wrong replacement will feel tight but fail under wind pressure.
• Glazing bead pops out or cracks. The vinyl bead becomes brittle after 8 to 12 years of UV exposure. In Weston, west-facing units hit this threshold faster; a bead that releases during a storm allows the glass to shift in its gasket, which is how we get calls for full sash replacement after what started as a $12 part.

Replacement Cost & What’s Included

These are installed prices for Weston, including measured survey, parts, labor, and the documented photo record you receive at completion. The range reflects glass size, floor level (third-story carries ladder time), and whether the original installation left accessible fasteners or buried them under trim. We do not quote one price and invoice another; Haven Clause 1 means the written price before work starts is the price on the final document. Every ES Windows replacement carries our 365-Day Done Right Promise and leaves with a photo record of the completed seal and lock engagement.

DIY or Call Us?

There is one check you can safely make yourself: open the sash fully, tilt it inward if it’s a tilt-wash model, and photograph every label, stamp, and hardware detail. That photograph saves us 20 minutes on site and often prevents a second trip if the part is non-standard.

What we do not recommend: removing a fixed sash from an impact-rated ES Windows unit, working above first story without proper ladder tie-off, or attempting to reglaze an IGU yourself. The laminated glass in Series 9000 and 10000 units weighs roughly 6 pounds per square foot; a 36-by-72-inch sash is unwieldy and unforgiving if the frame clips release unexpectedly. The glazing bead on these units seats under compression that requires specific setting blocks; hand pressure alone will not achieve the seal, and you’ll discover the leak during the next driving rain.

We are not in the business of talking capable homeowners out of simple work. We are in the business of documenting what we find so you know the full condition of the opening before you decide. Call (754) 812-9260 to schedule your measured survey; the written price comes before any tool is lifted.
