ECO Window Systems Home Additions & ADU: The West Palm Beach Owner’s Guide
If your ECO Window Systems windows or doors are failing inside a home addition or ADU in West Palm Beach, the fix usually costs between $45,000 and $130,000 when the project involves structural work, and far less when it’s a targeted part replacement. Bradford Remodeling Co West Palm Beach stocks ECO Window Systems-compatible components and can match most models from the job site or our local supply chain. The symptom picture is usually straightforward: you notice condensation between panes, a sash that won’t stay open, or a lock that no longer seats, and you realize the window that came with the addition is now the weak point.

Most owners call us after a storm or a brutal August afternoon when a window that should be sealing the envelope starts letting in humidity, noise, or worse. We’ve worked on additions and ADUs across West Palm Beach, from Northwood Village to the neighborhoods off Southern Boulevard, and the pattern is the same: the window was fine until the salt air and UV got to the seals, the rollers, or the balance system.
Which ECO Window Systems Models This Applies To

ECO Window Systems builds impact-rated and non-impact lines that show up frequently in West Palm Beach additions and ADUs, particularly in coastal retrofit work where building code requires wind-borne debris protection. The compatibility gotcha is this: ECO’s impact series uses a thicker frame profile and different balance hardware than their standard series, so a part ordered by “window size” alone will often be wrong. You need the series identifier from the manufacturer’s label, which is usually etched on the spacer bar between the glass panes or printed on a sticker along the top of the frame. Look for a string like “ECO-IMP” or “ECO-HR” followed by numbers that correspond to the glass package and frame depth.
The OEM-vs-aftermarket decision matters here. ECO’s factory parts carry a known warranty path and exact dimensional match. Quality aftermarket equivalents exist for rollers, locks, and weatherstripping on the standard series, and we use them when they meet or exceed the original spec and the homeowner wants to control cost. For impact-rated frames, we will not substitute aftermarket glass or structural components. That’s a code compliance issue, not a preference, and the wrong glass package can fail a hurricane inspection in West Palm Beach.
Bradford Remodeling Co West Palm Beach is an independent contractor. We are not affiliated with ECO Window Systems, which means we can give you a straight answer about whether an OEM part is worth the wait or an equivalent gets the job done without a brand loyalty angle.

Signs Your ECO Window Systems Home Additions & ADU Is Failing
- Condensation between the panes. This means the insulated glass unit has lost its seal and the argon or krypton fill is gone. It’s not a cleaning issue; the unit is done and needs replacement. In West Palm Beach humidity, a failed seal will also start to haze or streak permanently.
- The sash drops when you open it. Weak or broken balance springs are the usual cause on hung windows. On ECO’s standard series, the balances are replaceable; on some impact-series designs, the entire sash assembly has to come out because the balance is integrated into the frame extrusion.
- You can see daylight or feel air around the closed sash. This is weatherstripping compression loss, often accelerated by salt exposure. The fix is new weatherstripping and sometimes a realignment of the sash, but if the frame itself has bowed from settling in a West Palm Beach addition, the window needs shimming or full replacement.
- Rollers grind, stick, or the door derails on a slider. ECO sliding glass doors on ADUs in West Palm Beach take a beating from sand and fine limestone dust. The roller assemblies are replaceable, but a door that has been forced repeatedly may have also damaged the track, which changes the scope.
- Locks and latches that no longer line up. Frame settlement in an addition or ADU, especially on slab foundations, can shift the meeting rails enough that the locking points miss. Sometimes a strike plate adjustment fixes it; sometimes the frame has moved enough that the window needs a full reset with new anchors.
Replacement Cost & What’s Included

For a full ECO Window Systems window or door replacement inside a West Palm Beach home addition or ADU, installed pricing typically runs $4,500 to $15,000 per window unit when we’re replacing frame and glass together. A full addition or ADU envelope replacement project lands between $45,000 and $130,000 depending on the number of openings, the glass package, and whether impact-rated frames are required. Those numbers are the written range we quote before any work starts, and they include the part, labor, disposal of the old unit, and the finish work around the opening.
What drives the range: impact glass costs more than standard, larger openings cost more, and a second-story or awkward access point adds labor. Every estimate from Bradford Remodeling Co West Palm Beach is a written, line-item price before we touch anything. No numbers that move at the door. The work carries our 365-Day Done Right Promise: if the replacement fails inside a year, we come back and make it right at no charge.

AfterDIY or Call Us?
There are two things an owner can safely do before calling: document the symptom with photos and locate the manufacturer’s label so we can identify the exact ECO series and glass package. That saves a trip. Anything beyond that, we recommend you do not attempt. Impact-rated frames are heavy, the glass is laminated and under tension, and a window that falls on a track or drops a sash while you’re working on it can break bones or worse. The wrong removal technique can also damage the buck and flashing, which turns a $900 roller replacement into a $9,000 water intrusion repair in a West Palm Beach storm season.

FAQs

Expect 15 to 20 years on standard series and 20 to 30 years on impact-rated frames, but the salt air and UV in West Palm Beach shorten seal life on the insulated glass units to about 10 to 12 years before you start seeing hazing or condensation between panes. Call (728) 203-9809 and we’ll inspect the unit and tell you whether it’s a seal replacement or a full window replacement, with the price in writing either way.
Yes, if the frame is sound and the failure is isolated to hardware, the repair is usually a roller, balance, lock, or weatherstripping swap. If the insulated glass unit has failed or the frame has bowed from settling, replacement is the honest fix, and we’ll show you the numbers on both before you commit.
Most roller, balance, lock, and weatherstripping replacements on a West Palm Beach addition or ADU take 30 to 90 minutes per opening once the correct part is in hand. Full window replacements run half a day for a single unit, and we’ll give you the exact timeline with the written estimate.
We keep the common failure parts on hand for ECO’s standard and impact series: rollers, balances, lock sets, and weatherstripping in the most common West Palm Beach frame sizes. Specialty glass packages and full sashes are ordered by series number and usually arrive within a few days. Call (728) 203-9809 and we’ll verify what we have for your exact model before we schedule the visit.
