ECO Window Systems Window Replacement: The West Palm Beach Owner’s Guide

We stock and install ECO Window Systems-compatible window replacement across West Palm Beach, with most jobs priced between $340 and $780 per opening depending on series, glazing spec, and whether the frame is salvageable. Same-day installation is available when we have your series profile in our West Palm Beach warehouse, which we do for the 100 and 200 Series that dominate the 2016-2022 builds along Flagler Drive and the surrounding neighborhoods. Most owners discover the problem when the sash won’t stay open, the interlock gaps let in wind noise, or they spot delamination at the corner welds after a storm.

Which ECO Window Systems Models This Applies To

ECO Window Systems produces three residential lines we see regularly in West Palm Beach: the 100 Series single-hung and horizontal roller, the 200 Series double-hung and casement, and the 300 Series impact-rated line installed post-2018 in code-upgrade zones. The part you need depends on which line you have, and the label location tells you quickly.

Check the top of the sash on single- and double-hung units, or the hinge side of casements, for a stamped metal label with the series prefix (ECO-100, ECO-200, ECO-300) followed by a date code. The 100 Series uses a 2-1/4 inch frame depth with a single weatherstrip groove; the 200 Series jumps to 2-5/8 inches with dual bulb seals; the 300 Series impact line uses a reinforced 3-inch frame and laminated glass that cannot be swapped into a 100 or 200 frame without full replacement. We learned this the hard way on an early install in 2014, when we tried to retrofit impact glass into a standard frame and had to reorder the entire sash assembly. The ECO Window Systems OEM sash pack is our default, but for the 100 Series we also stock a quality aftermarket equivalent that matches the original U-factor and SHGC ratings at roughly 15% lower cost. We do not substitute on the 300 Series impact line; the NOA (Notice of Acceptance) documentation must trace back to the original manufacturer for permit compliance in Palm Beach County.

Signs Your ECO Window Systems Window Replacement Is Failing

• Sash drops or won’t stay raised. The coil balance assembly in ECO single- and double-hung units loses tension after 8-12 years of Florida heat cycling. In West Palm Beach, we see this accelerate when the exterior face spends afternoon hours in direct sun without awnings or deep overhangs.
• Visible moisture or fog between glass panes. The dual-seal system on ECO’s insulated glass units eventually breaches; the desiccant saturates and the spacer bar corrodes. Once the sightline shows haze, the IGU (insulated glass unit) is done. The glass pack must be replaced, not the whole window, if the frame and hardware are sound.
• Air infiltration at the interlock or sill. The pile weatherstrip compresses permanently over time, and the ECO 100 Series uses a single-fin design that wears faster than the dual-bulb system on the 200 Series. We check this with a smoke pencil during our measured survey.
• Corner weld separation or frame deformation. The vinyl extrusion expands and contracts; poor drainage at the sill weep holes traps water and stresses the welded corners. In West Palm Beach, salt air accelerates this if the weeps are clogged with paint or insect debris.
• Hardware operation grows stiff or noisy. The ECO casement operator uses a worm-gear mechanism that collects grit and loses lubrication. Forcing it strips the gears, and the replacement operator must match the arm geometry exactly or the sash won’t seal squarely against the frame.

Replacement Cost & What’s Included

What drives the range: the series, the glazing spec (clear, low-E, or low-E with argon), and whether we can reuse the existing frame or need to pull it to the rough opening. Our measured survey documents this before we write the quote. If the number isn’t on the page, it isn’t in the price. Every ECO Window Systems replacement we install in West Palm Beach carries our 365-Day Done Right Promise under the Haven Standard, and the documented photo record shows the before condition, the installed unit, and the final seal test.

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 confirm that the sash is fully seated in the track before calling. What we do not recommend: removing a sash that weighs 35-60 pounds of glass and vinyl, working above ground floor without proper fall protection, or attempting to reset a sprung coil balance under tension. The ECO double-hung balance system stores enough force to crack a finger or launch a block-and-tackle assembly across the room. We carry the specific balance cartridges, operator arms, and sash cams for all three ECO series on our West Palm Beach trucks, and our technicians are background-checked, uniformed, and identified by license number before arrival under Haven Clause 3. If your ECO Window Systems window is failing, call (561) 354-3861 to schedule your free measured survey. We will hand you the written price before a tool is lifted.
