ES Windows Window Replacement: The North Palm Beach Owner’s Guide

ES Windows window replacement in North Palm Beach typically runs $340-$780 per opening for standard vinyl impact units, with most jobs scheduled within 48 hours of the measured survey. We stock ES Windows-compatible hardware, glazing beads, and sash assemblies on our trucks, and we carry the full catalog for the 100, 200, 300, and 500 series - the four lines most commonly found in Palm Beach County homes built between 2015 and 2022. Most owners discover a problem when the sash won’t stay open, the lock no longer draws the meeting rail tight, or they feel salt air drafting through a frame that used to seal.

Which ES Windows Models This Applies To

ES Windows organizes its residential line by performance tier, and the part you need depends on which tier is in your wall. The 100 series is a non-impact vinyl single-hung with a 2-5/8 inch frame depth; the 200 series upgrades to impact-rated laminated glass with a reinforced vinyl master frame; the 300 series is aluminum impact with a thermal break; and the 500 series is the high-rise aluminum line with a 3-1/4 inch frame depth and heavier wall thickness. The label is usually etched into the glass corner or stamped on the spacer bar between panes. If the label is worn, measure the frame depth from interior to exterior trim - 2-5/8 inches points to 100 series, 3 inches to 200, 3-1/8 to 300, and 3-1/4 to 500.

We are an independent service provider - not affiliated with ES Windows - and we source both OEM hardware direct from the manufacturer and verified aftermarket equivalents where the OEM lead time exceeds what a North Palm Beach homeowner should wait. The gotcha we see most often: the 200 series uses a proprietary cam lock with a 7/16 inch spindle length, while the 300 series uses a 1/2 inch spindle. A 200 lock forced into a 300 frame will thread but will not draw the sash tight enough to pass a smoke-pencil test. We check spindle length and backset on every replacement, because the wrong lock feels right until the first storm.

Signs Your ES Windows Window Replacement Is Failing

• Sash drops or won’t stay open. The balance shoe or coil spring has lost tension. In North Palm Beach, we see this accelerate when owners pressure-wash the tracks and force water past the balance cover, corroding the spring housing. The sash feels heavy and slams shut when released.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed. Florida’s daily thermal cycling - 90-degree afternoons dropping to 70-degree evenings eight months a year - expands and contracts the spacer until the butyl seal separates. The fog is permanent; it will not clear with defoggers.
• Lock turns but meeting rail gaps remain. The keep striker has wallowed out or the cam lock spindle has stripped. Salt air accelerates galvanic corrosion between the zinc die-cast lock body and the aluminum frame, so the mechanism turns freely without engaging.
• Draft at the sill or jamb even when closed. The weatherstrip has compression-set or the glazing bead has shrunk. ES Windows uses a dual-durometer fin seal that hardens after roughly 8-10 years of UV exposure in South Florida; it no longer rebounds to fill the gap.
• Frame corner separation or visible bowing. The vinyl or aluminum frame has thermally stressed or the installation shim pack has settled. In North Palm Beach’s Lakeside Park neighborhood, we regularly find 1970s block homes where the original rough opening was out of square by 3/8 inch; the ES Windows unit was forced in, and the frame stress shows at the corners first.

Replacement Cost & What’s Included

The range depends on three things we document in the measured survey: the series and size of the existing unit, whether the rough opening needs correction, and whether the original installation used proper flashing integration with the stucco or frame. Our written quote itemizes each line - glass, hardware, labor, disposal - and the total you sign is the total on the invoice. Haven Clause 1: the measurement and the quote are the same document. Every replacement carries our 365-Day Done Right Promise; if the lock drags or the sash drifts inside twelve months, we return and correct it at no charge.

DIY or Call Us?

There is no high-tension spring or electrical hazard in a standard vinyl window replacement, but there is a precision hazard. An owner can safely check the label location, measure frame depth, and photograph the lock mechanism - we ask customers to text us those three things before we dispatch, and it saves everyone a trip. Where DIY goes wrong is in assuming the replacement part that looks right is right. We have retrieved half a dozen 200-series locks from Amazon boxes where the spindle was 1/16 inch too long; the homeowner forced it, stripped the threads, and turned a $180 balance replacement into a $480 sash rebuild.

Glass replacement is not a homeowner job. The IGU weighs 40-90 pounds depending on size and lamination, and the glazing beads must release in sequence or the frame distorts. If the opening isn’t right, the window isn’t right - that’s where we start.
