ES Windows Home Additions & ADU: The Fort Lauderdale Owner’s Guide
Adding square footage with ES Windows products in Fort Lauderdale typically runs $45,000 to $130,000 for a home addition, while a full ADU construction lands between $90,000 and $220,000. We install and service ES Windows frames, sashes, and hardware as part of larger addition and ADU builds across Broward County, and we stock common replacement parts for same-week turnaround. Most owners discover a problem the hard way: a window that won’t seal after a storm, a frame that’s pulling away from stucco, or glass that’s fogged between panes from Florida humidity. Luca Romano has seen it enough times to know the failure pattern before the homeowner even describes it.
Quick note before we get into it: Sawyer Remodel Fort Lauderdale is an independent general contractor, not a division of ES Windows. We work with their products constantly, but we’re not the manufacturer. That said, we know these windows the way only a remodeler who’s pulled hundreds of them out of South Florida walls can.
Which ES Windows Models This Applies To
ES Windows makes impact-rated aluminum and vinyl lines that show up all over Fort Lauderdale, from 1950s ranches near Victoria Park to newer builds out west toward Weston. The parts that fail are consistent across their series: the E-Impact 7000, E-Impact 8000, and the older ES Classic single-hung line. If you’re adding a bedroom wing, a second-story bump-out, or a detached ADU in a neighborhood like Coral Ridge or Rio Vista, you’ll need windows that match both code and the existing look. Matching is where we see most mistakes.
Here’s the compatibility gotcha: ES Windows changed their frame extrusion profile around 2018. A sash from a 2016 E-Impact 7000 will not seat correctly in a 2021 frame, even though both are stamped “7000 series.” You have to match the manufacturing date code etched in the lower corner of the glass, not just the series name. When we quote a home addition in Fort Lauderdale, we pull that code before we order anything. For OEM parts, lead times run 3 to 6 weeks. Quality aftermarket weatherstripping and balances are available faster, but we only use aftermarket on non-impact units. Impact glass assemblies should stay OEM, period.

Signs Your ES Windows Home Additions & ADU Are Failing
- Condensation between the panes. The argon gas seal has failed. In Fort Lauderdale, where the humidity sits above 70 percent most of the year, a failed seal shows up as permanent fog within weeks, not seasons.
- Hard cranking or sash that drops when opened. The window balance spring or block-and-tackle system is worn out. Older ES Classics used coil balances that lose tension unevenly, so one side sags before the other.
- Visible daylight or draft around the frame. The weatherstripping has compressed or the frame has shifted. On additions with new stucco, we sometimes see the buck opening settle slightly, pulling the frame out of square.
- Water staining on the interior sill after heavy rain. The weep holes are clogged or the exterior flashing was never lapped correctly. In Fort Lauderdale, a single summer storm can dump three inches in an hour, and a clogged weep system will find its way inside.
- Latch or lock that won’t engage. The keeper has come loose from the frame, or the sash has dropped enough that the lock point misses. This is a security issue, not a nuisance, especially on ground-floor additions.

AfterReplacement Cost & What’s Included
For a standalone ES Windows part replacement on an existing Fort Lauderdale home addition or ADU, you’re looking at $250 to $900 per window for weatherstripping, balances, locks, or latch hardware installed. A full impact sash replacement runs $1,200 to $3,500 depending on size and whether it’s a fixed or operable unit. If we’re building the addition or ADU from the ground up, the window package is baked into the $45,000 to $130,000 addition range, or $90,000 to $220,000 for a complete detached ADU.
What drives the cost: window size, impact certification rating, whether the frame itself is sound, and accessibility (second-story work costs more). Every quote includes labor, disposal of the old part, and our written warranty on the installation. No change orders after you approve the number. That’s the way we’ve run it since 2005, and Luca doesn’t make exceptions.
DIY or Call Us?
Let’s be straight about what’s safe and what isn’t. You can clean weep holes with a wire and clear debris from tracks. That’s maintenance, not repair. Beyond that, ES Windows impact units are heavy, tempered, and under compression in the frame. A sash that slips while you’re swapping a balance can take off a finger or shatter the assembly. We’ve seen a homeowner in Fort Lauderdale wedge a 2×4 under a dropped sash and call it fixed. The sash was still under spring tension. Not worth it.
If the part is a latch, a keeper, or weatherstripping, a careful owner can handle it. If it’s balances, springs, or glass, call us at (754) 354-7423. We’ll match the date code, bring the right part on the first trip, and you won’t be guessing.
FAQs
Weatherstripping on ES Windows units in Fort Lauderdale lasts 5 to 8 years before the salt air and UV break it down; balances typically last 10 to 15 years, and impact glass assemblies should hold for the life of the window unless a storm takes them out. Call (754) 354-7423 if your windows are in that age range and you’re noticing drafts or sticking.
A bent latch plate or a clogged weep hole can often be repaired in place, but a fogged impact glass unit or a snapped balance spring needs replacement parts, not a patch job. We’ll tell you which one you’ve got before quoting anything.
Most single-window part replacements in Fort Lauderdale take 45 minutes to 2 hours once the part is in hand; OEM glass orders add 3 to 6 weeks lead time because the sash comes from the ES Windows factory. We give you the timeline in writing before we start.
We keep common ES Windows weatherstripping, coil balances, and latch hardware for the E-Impact series on our trucks in Fort Lauderdale, but series-specific glass and frame extrusions are special-ordered to match your date code. That’s how we avoid the mismatch problem altogether.
