ECO Window Systems Home Additions & ADU: The West Palm Beach Owner’s Guide
If you’re planning a home addition or ADU in West Palm Beach and want ECO Window Systems-compatible windows and doors integrated into the build, Elmstead Remodeling West Palm Beach installs and coordinates these products as part of larger projects ranging from $45,000 to $130,000 for additions and $90,000 to $220,000 for a full ADU. Most homeowners reach out to us after discovering that a contractor they were considering either didn’t know the ECO Window Systems product line or wanted to swap in a cheaper window brand mid-project without updating the written scope. What we’ve learned is that the window and door package is rarely the first thing a family thinks about when planning an addition, but it’s often the first thing that goes wrong when the wrong components get ordered.
Our team walks every job site before a single drop cloth goes down. Graham Stein, our owner, grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending decades on jobs up and down the West Coast and eventually settling the crew into the West Palm Beach market. He still reviews every window schedule himself. In neighborhoods like Flamingo Park, we regularly see additions where the window and door openings were framed to one spec and the ECO Window Systems units arrived to another, and that gap is exactly where budgets and timelines quietly break.
Which ECO Window Systems Models This Applies To
ECO Window Systems builds impact-rated and non-impact aluminum and vinyl window and door lines that appear in a lot of West Palm Beach homes, especially those built or renovated after the early 2000s. The compatibility issue we see most often is not between model lines but between the structural opening size and the actual frame-to-frame dimensions of the window. ECO Window Systems units are specified by nominal size, but South Florida concrete block construction often means the rough opening differs from the window’s published size by a quarter inch or more. That quarter inch decides whether the flashing sits flat or the stucco patch looks right.
For home additions and ADUs, the more useful question is whether you want to match existing ECO Window Systems units in the main house, which is what we recommend when the addition is visible from the street. A mismatched window brand on a new addition in Flamingo Park or El Cid reads as an afterthought from the curb. We can source OEM ECO Window Systems units when the existing home has that product line, and we also work with quality aftermarket equivalents when the original line has been discontinued. The decision should be written into the scope of work before framing starts, with the brand, series, glass package, and hardware finish named in the document. That is the only way to keep an addition or ADU on budget without a crew standing idle over a window order nobody can confirm.
Styles & brands we work with
Signs Your ECO Window Systems Home Additions & ADU Is Failing
- Water staining at the interior sill or drywall corners. This is the classic sign that the flashing or the seal at the window frame has failed. In West Palm Beach’s wet season, a half-inch gap in flashing detail can pull water into the wall cavity within weeks, not years.
- Condensation or fog between the glass panes. The insulated glass unit has lost its seal. On ECO Window Systems units in South Florida humidity, this shows up first on east-facing windows that catch the morning sun and the afternoon rain in the same calendar day.
- Windows or doors that no longer close square. On a new addition or ADU, this usually points to settling or framing that was out of square from the start. The ECO Window Systems unit itself is often fine; the opening it was set into is not.
- Visible gaps between the window frame and the interior trim. This is not a trim problem. It means the window was shimmed incorrectly or the rough opening was oversized, and now air and moisture are moving through the wall assembly.
- Operable windows that drag or stick in one season. Aluminum and vinyl expand and contract with temperature. If a window only sticks during a specific season, the install clearance was cut too tight, and the frame is binding against the rough opening.

AfterReplacement Cost & What’s Included
For a home addition in West Palm Beach, the full project typically runs $45,000 to $130,000, with the window and door package often sitting between 8 and 15 percent of that total depending on how many openings the design calls for and whether you are matching existing ECO Window Systems units in the main house. A full ADU construction project runs $90,000 to $220,000, and windows and doors are among the line items that can move that number meaningfully if the original quote assumed a lower-cost window brand and the scope later changed to ECO Window Systems-compatible units.
What we put in writing, every time, is the installed price for the window or door package broken out as its own line item: the units by brand and series, the glass package, the hardware finish, the flashing detail, and the labor to set and seal each opening. There is no estimate that grows after the crew arrives. If the existing ECO Window Systems opening needs reframing or a new buck system, that line item is in the written scope before the first tool is unpacked. The 365-Day Done Right Promise covers every completed project, including the window and door package on an addition or ADU. If it is not done right, we make it right.
DIY or Call Us?
Replacing or installing a window on a framed opening is not a weekend project. The units are heavy, and on a second-story addition in West Palm Beach, getting an ECO Window Systems window to the opening safely is a two-person job with proper lift equipment. If the rough opening is even slightly out of square, which we see on roughly half of the additions we inspect, the window needs shimming and the flashing detail needs to be redone. A homeowner can check the basics: look for water staining at the sill corners, note whether the window closes square, and check the interior trim for gaps. But setting a window correctly so the wall cavity stays dry through a South Florida hurricane season is not a beginner task.
If you’re in the middle of planning an addition or ADU and want the window and door package handled by a crew that names the product and the price before the work starts, call us at (728) 203-3270. We’ll give you a written scope, a firm price for the window and door line items, and a start date we actually keep.
FAQs
Expect 15 to 25 years from the window units themselves, with the glass seal often failing first in coastal West Palm Beach humidity, typically around year 12 to 15 on east-facing openings. Frames can last longer, but the flashing and sealant around the frame usually need attention by year 10. Call (728) 203-3270 if you want us to look at an existing unit or plan a window schedule for a new addition.
Yes, in specific cases. If the insulated glass unit has failed, the glass panel can be replaced without replacing the frame. If the frame itself is warped or the rough opening is out of square, a proper repair usually means removing and resetting the window, which is effectively a replacement with extra labor. We’ll tell you which situation you have, in writing, before any work starts. Call (728) 203-3270 for an honest assessment.
For a typical addition with 8 to 15 openings, plan on 2 to 4 working days for the window and door installation, assuming the rough openings are framed correctly. If reframing or stucco repair is needed, that adds time. Our written scope includes a firm start and end window for every phase. Call (728) 203-3270 and we’ll put the schedule in writing.
We do not stock full ECO Window Systems window units on a shelf; these are ordered per project to match the exact sizes, glass packages, and hardware finishes in your scope of work. We do keep common flashing materials, sealants, shims, and fasteners on the truck so the crew is not leaving the job site for a trip to a supply house mid-install. Call (728) 203-3270 and we’ll confirm lead times for the specific units you need.
