ES Windows Window Replacement: The Lantana Owner’s Guide

ES Windows window replacement in Lantana typically runs $340 to $890 per opening installed, depending on series, size, and whether the unit is impact-rated or non-impact. We stock ES Windows-compatible sashes, balances, and complete frame assemblies for same-day replacement on most residential series found in Lantana homes built between 2015 and 2022. Most owners first notice trouble when a sash won’t stay up, condensation appears between glass lites, or the lock no longer draws the meeting rails tight against the weatherstrip.

Which ES Windows Models This Applies To

ES Windows manufactures three residential lines we see regularly in Lantana: the ES 100 Series (non-impact vinyl), the ES 200 Series (impact-resistant aluminum), and the ES 300 Series (thermally broken aluminum impact). The series marking is stamped on the spacer bar between glass panes, visible when you open the sash and read the edge of the insulated glass unit. If that label is worn, measure the visible glass width and height to the nearest eighth-inch, then check the frame depth: 2-5/8″ for the 100 Series, 3-1/4″ for the 200, and 3-1/2″ for the 300.

We carry OEM ES Windows sashes and hardware, but we also stock quality aftermarket balances and rollers from Truth Hardware and Caldwell that match ES specifications at lower cost. The aftermarket route makes sense for discontinued color finishes or when ES factory lead times stretch past three weeks. For impact-rated units in Lantana, we stick with OEM glass and frames; mixing aftermarket components into an impact assembly voids the Miami-Dade NOA certification, and that matters when your insurer asks for documentation after a named storm.

Signs Your ES Windows Window Replacement Is Failing

• Sash drops or won’t stay open. The coil balance or block-and-tackle system has lost tension. In Lantana’s salt air, we see balance corrosion accelerate after year six, especially on east-facing windows within a mile of the beach.
• Fog between glass panes. The insulated glass unit (IGU) seal has failed, allowing moisture into the airspace. Once the desiccant saturates, the fog becomes permanent; the IGU needs replacement, not cleaning.
• Lock engages but meeting rails gape. The keep or strike plate has worn, or the sash has sagged on worn balances, throwing the alignment off. A misaligned lock stresses the multipoint hardware and will eventually snap the spindle.
• Frame corner weeps stain the sill. Weep holes are clogged with debris or the sill pan is pitched wrong. Water backs up into the wall cavity; we’ve found rotted jack studs in Lantana homes where this went unaddressed for two seasons.
• Operable sash sticks or grinds. Rollers are flat-spotted or the track has accumulated aluminum oxide. The 200 Series track is anodized aluminum; once the anodizing wears through, the bare metal galling accelerates fast.

Replacement Cost & What’s Included

What drives the range: unit size, impact rating, and whether the existing frame is square within 1/4″. We measure every opening with a laser level and document the readings on the survey sheet you keep. If the frame is out of plumb, we note the shim schedule and any trim repair before quoting; no change orders after we start. Every replacement carries our 365-Day Done Right Promise under the Haven Standard, and the photo record shows before, during, and after.

DIY or Call Us?

An owner can safely check a few things: clear weep holes with a pipe cleaner, verify the lock keep is tight to the frame, and photograph the spacer bar label for us. Beyond that, ES Windows sashes are heavy, particularly the impact-rated units with laminated glass, and the balance systems store significant spring tension. A released balance can snap across the opening with force enough to break a finger or crack the new IGU. We don’t recommend homeowner removal.

We stock ES Windows-compatible components on our Lantana trucks, and most residential replacements finish in under two hours per opening. If you’re unsure whether the issue is the glass, the sash, or the frame, call (561) 461-2062 and we’ll walk through what to photograph. The estimate is free, and we review competitor quotes at no charge.

FAQs

How long do ES Windows units last in Lantana’s climate?

Non-impact vinyl units typically see 15 to 20 years of serviceable life; impact aluminum units often reach 25 years if the hardware is maintained. Salt exposure within a half-mile of the Intracoastal or Atlantic accelerates balance and roller wear by roughly 30 percent. Call (561) 461-2062 for an exact quote on your series and location - estimates are free.

Can the glass be repaired instead of replaced?

Sealed IGU fog cannot be reversed; the unit must be replaced. Minor hardware issues like a worn lock or roller can often be addressed component-by-component, which we always explore first. Call (561) 461-2062 for an exact quote - estimates are free.

How long does a typical replacement take?

IGU or sash replacement in an existing ES Windows frame takes 90 minutes to two hours per opening, assuming the frame is plumb and the interior trim is intact. Full frame replacement requires four to six hours and a second visit for finishing trim. Call (561) 461-2062 to schedule - estimates are free.

Do you stock ES Windows parts, or do you order them?

We stock balances, rollers, locks, and keepers for all three ES residential series on our Lantana trucks. Complete sashes and IGUs are ordered to measured size, with typical turnaround of three to five business days for standard colors; custom finishes add one week. Call (561) 461-2062 to confirm availability for your series - estimates are free.

Sightline Windows & Doors Lantana is independently owned and operated under the Haven Standard, with no affiliation to ES Windows. We also stock and install PGT, CGI, and CWS product lines.

Sonia Raman, who leads our operation, grew up in Los Angeles and learned to read a rough opening at Los Angeles Trade-Technical College before she ever drove the freeway. She’s spent the better part of two decades measuring and installing across South Florida, and her crew has logged years of work on Lantana beachfront homes where salt air and hard summer storms test every seal and balance. She still writes down the exact U-factor and impact rating before any contract is signed - numbers on the page, not promises in the air. “Measure it right the first time. Everything after that is just paperwork.”
