ES Windows Window Replacement: The Boynton Beach Owner’s Guide

ES Windows window replacement in Boynton Beach typically runs $340-$780 per opening for standard vinyl and aluminum units, with impact-rated ES Windows models ranging $890-$1,450 installed. We stock ES Windows-compatible sashes, balances, and hardware for same-day replacement on most series, and we carry the full catalog for next-day ordering on custom sizes. Most Boynton Beach homeowners discover the problem when a window won’t stay open, fogs between the panes, or the lock no longer seats flush - usually after a storm season or once the original sealant starts letting Intracoastal salt air reach the frame.

Which ES Windows Models This Applies To

ES Windows produces three residential lines you’ll find in Boynton Beach homes built between 2015 and 2025: the ES 100 Series (single-hung vinyl, non-impact), ES 200 Series (aluminum impact-rated), and ES 300 Series (thermally broken aluminum, HVHZ-certified). The label is stamped on the top rail of the sash or etched into the spacer bar between glass panes; if the label is worn, measure the daylight opening width and height to the nearest 1/8 inch, and note whether the frame is vinyl or aluminum - the balance systems and glazing beads are not interchangeable.

We source OEM ES Windows parts direct from the Miami distribution center, though for discontinued 100 Series sashes we use an aftermarket equivalent that matches the original U-factor (0.30) and SHGC (0.25) spec. One compatibility gotcha: the 200 Series impact units shipped before 2019 used a 7/8-inch laminated glass pack, while post-2019 production moved to 1-inch. Ordering the wrong sash depth leaves a visible step in the sightline and compromises the DP-50 rating. We verify this on every job with a digital caliper before any part leaves our truck.

Signs Your ES Windows Window Replacement Is Failing

• The sash drops or won’t stay raised. This points to a failed coil balance or broken pivot bar in the ES 100 Series, or a corroded constant-force spring in the 200 Series aluminum units. In Boynton Beach, we see this accelerate when salt air penetrates the balance shoe - the corrosion flakes jam the mechanism.
• Fog or moisture between the glass panes. The insulated glass unit (IGU) seal has failed, allowing humid Florida air to enter the airspace. Once the desiccant in the spacer bar saturates, the fog becomes permanent; the IGU must be replaced, not the entire frame.
• Lock tongue doesn’t engage or rattles in wind. The keeper has shifted or the cam lock has worn. On ES 200 Series impact windows, this is a security issue - the lock is part of the pressure-equalization system that lets the window survive a missile impact test.
• Frame corners weep water during heavy rain. The weep holes are clogged, or the end dam sealant has separated. In homes near Boynton Harbor Marina, we find this caused by salt crystallization blocking the drainage path, not simple debris.
• Visible daylight around the closed sash. The bulb seal or pile weatherstrip has compressed past recovery, or the sash has sagged due to hinge wear. The air leakage coefficient rises, and your cooling load climbs with it.

Replacement Cost & What’s Included

What drives the range: glass thickness (impact vs. non-impact), frame color (white is standard; bronze and clay carry a 12-15% upcharge), and whether the original installation used the correct sealant for the substrate. We quote by the documented measured survey, not by the opening - Haven Clause 1 means the price you sign is the price on the invoice. Every ES Windows replacement carries our 365-Day Done Right Promise and a documented photo record of the completed sealant joints.

DIY or Call Us?

There is safe checking and there is unsafe attempting. A homeowner can verify the series label, clear weep holes with a pipe cleaner, and photograph the lock mechanism for us to identify - that saves time and doesn’t risk the warranty. What we do not recommend: removing a sash with a failed balance (the spring is under tension and can release unpredictably), cutting out an IGU (the glass pack is heavy and the vinyl glazing bead snaps under uneven pressure), or re-caulking the exterior perimeter (the wrong sealant on stucco or Hardy Board traps moisture and voids the frame warranty).

Sonia Raman keeps a list of every window she has had to pull and replace because a previous installer used the wrong sealant. It is longer than she would like. That is why we check our crew’s caulk joints before any truck leaves a Boynton Beach site. If you are unsure what failed or what part number matches, call us. The estimate is free, and we bring the measured survey with us.
