ES Windows Window Replacement: The Boca Raton Owner’s Guide
Replacing a failed ES Windows unit in Boca Raton typically runs between $850 and $2,400 installed, depending on window size, glass package, and whether the frame needs full replacement or just the sash. We stock ES Windows-compatible replacement sashes and glass units on our trucks, and most straightforward swaps go in the same day we arrive. The most common call we get starts with a homeowner noticing condensation between the glass panes, a crank that’s gone stiff, or a window that no longer seals against South Florida humidity.
Here’s the reality we see across Boca Raton: ES Windows builds a solid product, but salt air, hurricane-season pressure swings, and relentless UV exposure take a toll on any window eventually. When a part fails, you want it matched correctly, not retrofitted with something close enough. That’s where we come in.
Which ES Windows Models This Applies To
We work on the full ES Windows lineup, including their impact-rated and non-impact series commonly installed in Boca Raton homes and condos. The most frequent models we replace parts for are the ES Windows 7000 and 8000 series, along with their aluminum single-hung and casement lines found throughout communities like Boca West, St. Andrews, and homes near Mizner Park.
Identifying the right replacement comes down to a label check and a measurement. Every ES Windows unit has an identifying sticker or etching, usually on the top edge of the sash or inside the frame track. That sticker carries the series code and glass specifications you need. If the sticker’s faded (common after years of Florida sun), we measure the visible glass dimensions, frame depth, and interlock profile to pin down the exact match.
One compatibility gotcha worth knowing: ES Windows uses an interlocking meeting rail design on their horizontal sliders and single-hungs that doesn’t always play well with generic aftermarket sashes. A universal replacement sash from a big-box store often leaves a gap at the interlock, which means drafts, leaks, and a failed seal the first time a Boca Raton afternoon storm rolls through. For ES Windows units, we recommend OEM or OEM-spec replacements rather than universal fits. The cost difference is modest; the performance difference is not.
Signs Your ES Windows Window Replacement Is Failing
- Condensation or fog between the panes. The seal on the insulated glass unit has failed. Once the seal goes, the argon or krypton gas escapes and you’re left with a window that fogs and loses its insulating power. We see this constantly on west-facing Boca Raton windows where the afternoon sun bakes the seal until it gives out.
- Crank or sash movement has gone stiff or seized. The operator mechanism or balance system is worn. Coastal salt air corrodes the internal hardware faster than you’d expect, and once the gears strip or the balance spring snaps, the sash won’t stay put or won’t open at all.
- Visible corrosion or white chalky residue on the aluminum frame. Salt-driven oxidation is eating the finish and eventually the frame itself. Left alone, the corrosion spreads and compromises the structural integrity of the frame, which turns a sash replacement into a full-frame job.
- Water stains or soft drywall beneath the window after rain. The weatherstripping or frame seal has failed. Water is getting past the window and into the wall cavity, which is where your real problem starts. We’ve opened enough walls in Boca Raton to know that a small window leak becomes a mold remediation project if ignored.
- The window won’t lock or the lock feels loose. A misaligned or failed lock means the window isn’t sealing properly, and on impact-rated windows, it means the unit won’t perform as designed when you need it most. A loose lock on an ES Windows impact unit isn’t a minor annoyance; it’s a hurricane-protection failure waiting to happen.
Replacement Cost & What’s Included
For Boca Raton homeowners, here’s the price picture in plain terms:
- Sash replacement only (glass and frame insert): $450-$1,100 installed, depending on size and glass package.
- Full window replacement (frame and all): $850-$2,400 installed for standard sizes; larger custom openings run higher.
- Impact-rated replacement units: Add $200-$600 per window over non-impact pricing, depending on the design pressure rating and glass thickness.
- Hardware-only repair (crank, lock, balance): $125-$350 when the glass and frame are still sound.
The price spread gets driven by three things: window dimensions, whether you’re replacing impact or non-impact glass, and whether the existing frame is salvageable. We write line-item quotes so you see the part cost, labor, and any disposal or permit fees separately. No lump-sum mystery numbers. And every replacement window we install carries our workmanship warranty on top of the ES Windows product warranty. If we install it and it fails due to our work, we fix it. Period.

DIY or Call Us?
Here’s the honest split. You can safely do a visual inspection: check the frame for corrosion, look for condensation between panes, test the crank and lock operation, and read the sticker to identify your model. What you shouldn’t do is attempt to remove an impact-rated sash or replace glass yourself. ES Windows impact units are heavy, the glass is laminated and thick, and the frame tolerances are tight. One wrong move and you’ve got a shattered sash, a voided warranty, and a bigger bill than if you’d called us first.
Replacing the window itself means removing the old unit without damaging the surrounding stucco or framing, shimming and squaring the new one properly, sealing it against Boca Raton’s sideways rain, and verifying the installation meets code. That’s our job, and we’ve done it for over 15 years across South Florida. Call (561) 816-5648 and we’ll come take a look, give you a straight answer on what’s actually failed, and quote it before any work starts.
FAQs
In Boca Raton’s coastal climate, ES Windows typically last 15 to 20 years before seal or hardware failure becomes likely, though impact-rated units in shaded east-facing openings can go 25 or more. The salt air and intense UV exposure accelerate seal degradation compared to inland installations.
It depends on what failed: a worn crank, broken balance, or failed lock can often be replaced as individual components, while failed glass seals, corroded frames, or cracked impact glass require full sash or window replacement. Call (561) 816-5648 and we’ll tell you honestly which path makes sense for your specific window.
A straightforward sash or full-window replacement takes our crew two to four hours from arrival to cleanup for most standard ES Windows units. Larger impact casements or custom openings may take longer, but the vast majority of Boca Raton replacements are done in a single visit.
We keep ES Windows-compatible sashes, insulated glass units, hardware, and weatherstripping on our trucks, and we also stock parts for PGT, CGI, and CWS units for homes that mix brands. That means we can match most ES Windows replacements on the first visit rather than scheduling a follow-up once parts arrive.
