ES Windows Window Replacement: The Miramar Owner’s Guide

ES Windows window replacement in Miramar typically runs $340-$780 per opening installed, depending on series, glazing package, and whether the frame is preserved or replaced entirely. We stock ES Windows-compatible sashes, hardware, and full-frame units on our Miramar trucks, and most replacements are surveyed and started within two business days. Homeowners usually notice the problem first as a draft they can’t trace, or a sash that won’t stay open - the kind of small failure that gets worse fast once salt air starts working on the balance shoe or the weatherstrip gap widens.

Which ES Windows Models This Applies To

ES Windows manufactures three residential lines we see regularly in Miramar: the ES 100 Series (single-hung and horizontal roller), the ES 5000 Series (impact-rated single-hung and fixed), and the ES 8000 Series (heavy commercial-grade impact). The label you’re looking for is a small etched mark on the glass spacer or a foil stamp on the frame interior, usually reading “ESW” followed by a four-digit date code and series prefix. If the label is sun-faded - common on west-facing units in Miramar’s lake-adjacent neighborhoods like Lake Lucerne - measure the daylight opening width and height to the nearest 1/16 inch; ES Windows uses true fractional sizing, not nominal, so a 35-7/8″ callout is not the same as 36″.

We carry OEM ES Windows sashes and balances, and we also stock quality aftermarket equivalents from CWS and PGT where the original part is back-ordered. The aftermarket decision depends on whether your unit is still under ES Windows’ original 10-year glass seal warranty; mixing non-ES glass in a warranted sash voids coverage. We document this on the written scope before you sign. Sightline Windows & Doors Miramar is an independent service provider, not affiliated with ES Windows.

Signs Your ES Windows Window Replacement Is Failing

• Sash drops or won’t stay raised. The coil balance system has lost tension, usually from corrosion at the pivot bar slot. In Miramar, we see this within 8-12 years on non-impact units facing the canal or lake, where humidity cycles are sharper.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed. ES Windows uses a dual-seal system, but South Florida’s UV exposure degrades the PIB primary seal faster than the manufacturer rates for inland climates.
• Frame corner gaps or sealant cracking. Thermal expansion stress at the mechanically joined corners. The ES 100 Series uses a screw-corner construction that can work loose; the 5000 and 8000 Series are fusion-welded and rarely show this.
• Difficulty locking or engaging the sash. The keep or cam lock has worn, or the frame has settled out of square. We check with a digital level; anything over 1/8 inch in 36 inches means the frame needs adjustment, not just hardware.
• Air infiltration at the meeting rail or sill. Weatherstrip compression set. ES Windows’ original pile weatherstrip is 5/16 inch; aftermarket replacements at 1/4 inch don’t fill the same channel and leak within a season.

Replacement Cost & What’s Included

The range reflects glazing options: clear, Low-E, or Low-E with laminated impact glass. Every quote is itemized by line - frame, glass, hardware, labor, disposal - and the total you sign is the total on the invoice. Haven Clause 1: Have it in writing. No change orders unless you add scope. The 365-Day Done Right Promise covers installation and workmanship; glass seal failure within the manufacturer’s term is handled direct with ES Windows or through us as your preference.

DIY or Call Us?

There’s safe checking, and there’s risky work. A homeowner can verify the model label, measure the daylight opening, and photograph the failure for our review - we use those photos to pre-order parts and shorten the site visit. What we don’t recommend: removing a sash with a failed balance (uncontrolled drop hazard, especially on upper floors), cutting sealant on an IGU (broken glass risk), or attempting to reglaze an impact-rated unit (the laminate interlayer requires controlled temperature and pressure to seat correctly).

We’ve replaced ES Windows units in Miramar homes where a DIY sash removal cracked the main frame jamb, turning a $400 sash job into a $700 full-frame replacement. Measure it right the first time. Everything else follows from that. Call (754) 260-1468 and we’ll schedule a survey; the written price comes before any work starts.
