ECO Window Systems Window Replacement: The Kendall Owner’s Guide

ECO Window Systems window replacement in Kendall typically runs $340-$780 per opening installed, depending on frame material, glass package, and whether the original was impact-rated. We stock ECO Window Systems-compatible frames, sashes, and hardware for same-day replacement on most residential series, and we carry the full measurement record from survey to invoice so the new unit matches the opening exactly. Most Kendall owners first notice trouble when a sash won’t stay open, a lock bar doesn’t engage, or they feel air movement around a frame that used to seal tight.

Which ECO Window Systems Models This Applies To

ECO Window Systems manufactures three residential lines you’ll find in Kendall homes: the ES 100 Series (non-impact vinyl), the ES 3000 Series (impact-rated aluminum), and the ES 5000 Series (thermally broken aluminum with impact option). The label is usually etched into the glass corner or stamped on the frame edge; if it’s worn off, we measure the frame depth, check the glazing bead profile, and match the lock mechanism to determine the series.

The ES 3000 and ES 5000 use a proprietary interlock design that differs from standard Miami-Dade hurricane products. Aftermarket frames will fit the rough opening, but the interlock geometry often leaves a gap under pressure testing. We source OEM ECO Window Systems sashes for those two series and use verified aftermarket only on the ES 100 where the load requirements allow. One compatibility gotcha: the ES 5000 thermally broken frame changed its drainage channel depth in 2019, so a 2018 sash dropped into a 2020 frame will weep water into the track during a Kendall summer downpour. We check the manufacturing date stamp before ordering.

Signs Your ECO Window Systems Window Replacement Is Failing

• Sash drops or won’t stay open. The balance system has lost tension. On ECO Window Systems single-hungs, the coil balance is housed in the jamb liner; once a coil fractures, the sash weight overcomes the remaining tension and gravity takes over.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed. In Kendall’s humidity, this happens faster than inland Florida because daily thermal cycling stresses the edge seal; we see it most on west-facing units after seven to ten years.
• Lock bar won’t extend or latch. The multipoint lock mechanism has corroded or the keeper has shifted. ECO Window Systems uses a stainless steel bar in impact-rated units, but the zinc housing still oxidizes if the weep holes clog with Dadeland-area pollen and grit.
• Frame corner separation or visible bowing. Thermal expansion has stressed the fusion weld or mechanical corner. Vinyl frames in Kendall absorb more heat than aluminum; a dark bronze ES 100 on a south wall can see frame temperatures above 140°F, which accelerates material fatigue.
• Draft or water intrusion at the sill. The sill dam or weatherstrip has compressed or torn. The original ECO Window Systems fin-seal gasket has a ten-year compression set rating; after that, it doesn’t rebound enough to seal against wind-driven rain.

Replacement Cost & What’s Included

What drives the range: glass package (clear vs. Low-E vs. impact laminate), frame finish (white, bronze, or custom color match), and whether the original installation left enough rough-opening tolerance for a clean retrofit or we need to trim back stucco. Every quote is written before work starts, line-itemed by labor and material, and matches the measured survey you keep. The 365-Day Done Right Promise covers the installation; OEM glass carries the manufacturer’s warranty against seal failure.

DIY or Call Us?

There’s a safe middle ground and a hard stop. A homeowner can check the label location, photograph the lock mechanism, and clear weep holes with a pipe cleaner. What we don’t recommend: removing an impact-rated sash without temporary bracing, cutting sealant beads with a utility knife on a ladder, or attempting to reglaze an IGU. The ES 3000 and ES 5000 sashes weigh 40-70 pounds depending on size; a dropped sash is a broken foot or a shattered impact laminate that costs more than the original repair.

We measure once, document it, then cut. Our crews carry the full ECO Window Systems hardware matrix on the truck, and Sonia Raman reviews every survey against the factory spec sheet before ordering. If you’re staring at a sash that won’t behave, call (786) 321-3319 and we’ll schedule a free estimate with a written price you can compare.
