ES Windows Home Additions & ADU: The West Palm Beach Owner’s Guide
Planning a home addition or ADU in West Palm Beach with ES Windows products in the build spec? We install and finish ES Windows-compatible home additions and ADUs, and a full addition typically runs $45,000 to $130,000 depending on square footage, foundation work, and finish level. Most owners call us when they’ve already got ES Windows units on order or sitting in the garage and need a framing and installation plan that matches those exact window specs, because a window that doesn’t seat right in a Florida wall is a leak waiting for the next hurricane season.
You’ll usually discover you need this page after a contractor either ghosts you mid-plan or tells you the ES Windows rough openings are “close enough.” They aren’t. West Palm Beach building code and ES Windows’ own tolerances don’t leave room for close enough, and we’ve corrected enough botched rough framing around Northwood Village to know the difference between a wall that holds a window and a wall that holds a window for twenty years.
Which ES Windows Models This Applies To
ES Windows manufactures impact-rated aluminum and vinyl lines sized for Florida’s hurricane zones, and the rough-opening dimensions are series-specific. A Series 7000 impact window does not drop into the same rough opening as a Series 4000 non-impact unit, even when the glass dimensions look identical. The frame depth, anchoring flange placement, and required shim gap all change. Before you frame anything, check the white label on the side of the sash or the packing slip. It lists the series number, the exact rough opening width and height, and the design pressure rating. That DP rating is the number West Palm Beach inspectors will check against your elevation and wind zone, and it’s not negotiable.
On the OEM versus aftermarket question: ES Windows parts and extrusions are proprietary, and there is no quality aftermarket equivalent for the frame components. For hardware like rollers, locks, and weatherstripping, aftermarket options exist, but we only use parts that match the original spec sheet. A lock that doesn’t seat flush on an impact-rated window is a false security point, and we won’t install one.

Signs Your ES Windows Home Additions & ADU Is Failing
- Gaps between the window frame and the rough opening. The framing was cut too large or the wrong series opening was used. In West Palm Beach humidity, that gap becomes a moisture path within one season, and foam backer rod is a temporary patch, not a fix.
- Windows that bind or require force to open and close. The frame was shimmed incorrectly or the header sagged after the roof load settled. Forced operation wears the ES Windows roller hardware and misaligns the sash within months.
- Water staining at the sill or the interior drywall beneath the window. The flashing detail wasn’t done to ES Windows’ install spec. Florida’s sideways rain will find any installation shortcut, and once moisture is in the wall cavity, you’re looking at mold remediation on top of the window work.
- Cracking at the drywall corners above the window opening. The header was undersized for the span or the point loads were not transferred to the foundation properly. This is a structural problem wearing a cosmetic symptom.
- Audible wind whistle or drafts around the frame. The reveal gap between the window and buck was not sealed correctly, or the wrong backer rod density was used. In an impact window, that means the design pressure rating is compromised, and the window may not perform when it matters.

AfterReplacement Cost & What’s Included
Home additions with ES Windows in West Palm Beach run $45,000 to $130,000, and ADU construction with the same window package runs $90,000 to $220,000. The spread comes down to foundation type, whether the addition ties into the existing roofline or gets a new roofline, finish selections, and how many ES Windows units the design calls for. A slab-on-grade addition with a simple roofline and three windows sits at the low end. A second-story addition or an ADU with a full kitchen and bath climbs toward the top of the range.
Every estimate from Curtis Lane includes a written line-item breakdown before any work starts. You’ll see the framing and structural scope, the window installation count and specs, the finish carpentry, and the permit line. No number moves at the door. The 365-Day Done Right Promise covers the installation work for a full year, and if something fails inside that window, we come back and correct it at no charge.
DIY or Call Us?
What you can safely check yourself: the ES Windows label on each unit to confirm the series number and rough opening, and a simple visual inspection for gaps, cracking drywall, or water staining. Those observations help you describe the problem when you call.
What you should not attempt yourself: cutting or reframing rough openings, moving headers, re-flashing an impact window, or re-shimming a frame that has settled. This is structural and waterproofing work, and a wrong cut in a load-bearing wall is a safety issue, not a weekend project. Window installation in West Palm Beach also requires a permit and an inspection. If the framing or flashing is done wrong, you’ll be paying twice: once for the attempt and once for us to do it correctly. Call (728) 203-9809 and we’ll give you a straight number and a full scope before you spend another weekend staring at the gap.
FAQs
ES Windows impact units have a realistic service life of 20 to 30 years in West Palm Beach’s salt air and UV exposure, though the frame and glass will outlast the hardware. Locks, rollers, and weatherstripping typically need attention around the 10 to 15 year mark. If your addition windows are newer than that and already failing, the problem is usually the installation, not the window. Call (728) 203-9809 and we’ll tell you which one you’re dealing with.
That depends on what’s failing. Weatherstripping, locks, and rollers can be replaced without pulling the window. But if the rough opening was cut wrong, the header is undersized, or the flashing is compromised, the fix is to remove the window, correct the framing or waterproofing, and reset it. Patching around a bad installation only delays the same failure. Call (728) 203-9809 for an honest assessment and a written price either way.
A standard window correction, pulling and resetting one unit with re-flashing, is usually a one-day job once the permit is in hand. A full addition or ADU with multiple ES Windows units runs weeks to months depending on the structural scope, but we give you a written schedule with the written price. No schedule surprises, same as no price surprises. Call (728) 203-9809 to talk through your timeline.
We keep common ES Windows hardware on the truck: rollers, locks, keepers, and weatherstripping for the series we install most in West Palm Beach. Frame extrusions and glass packages are ordered per job because they’re series- and size-specific, and we won’t substitute a part that isn’t spec’d for your unit. We also work with KraftMaid, Cambria, and Silestone on the finish side, so the entire addition can be sourced and scheduled through one crew. Straight number, full scope, no surprises after the invoice.
If you’re planning a home addition or ADU in West Palm Beach and you’re committed to ES Windows, call (728) 203-9809. We’ll walk the site, check your plans against the window specs, and hand you a written price before any work starts. No pressure, no games, just a clear scope and a crew that shows up and finishes the job.
