ES Windows Window Installation: The Lighthouse Point Owner’s Guide
ES Windows window installation in Lighthouse Point typically runs $340-$780 per opening for standard replacement, depending on whether the job involves a direct-fit insert or a full-frame tear-out with stucco repair. We stock ES Windows hardware and fasteners on every truck and can usually schedule installation within 48 hours of survey. Most Lighthouse Point owners first realize they need this service when the sash won’t stay open, the interlock gaps let water through during a driving rain, or they feel the frame flexing in the jamb - all signs the original install has shifted, settled, or was never square to begin with.
Which ES Windows Models This Applies To
ES Windows produces three residential lines we see regularly in Lighthouse Point: the ES 5000 Series (non-impact vinyl), the ES 8000 Series (impact-rated aluminum), and the ES Elite line (thermally broken aluminum with reinforced corners). The critical compatibility issue is that ES Windows changed its frame depth and corner-key geometry in 2019, so a sash or frame ordered for a pre-2019 unit will not seat correctly in a post-2019 opening. We check this by reading the etched production code in the glass corner - the fourth digit indicates the year - and by measuring the pocket depth with a digital caliper, not a tape measure.
For hardware, ES Windows uses proprietary tilt latches and interlock keepers on the 8000 and Elite series that are not interchangeable with PGT or CGI equivalents, even when the profile looks similar. We carry OEM ES Windows fasteners and weatherstrip on the truck, but we also stock a verified aftermarket interlock keeper that matches the 8000 Series spec at roughly 60 percent of OEM cost. The decision between OEM and aftermarket comes down to whether the job is going through a building department inspection - some Lighthouse Point inspectors flag non-OEM hardware on impact-rated units, and we note that on the written scope before you sign.
Signs Your ES Windows Window Installation Is Failing

- The sash drops or won’t stay open. This usually means the balance shoe has detached from the jamb liner or the coil spring has lost tension. In Lighthouse Point, we see this most often on east-facing windows where morning salt spray corrodes the balance housing faster than the manufacturer rates for inland use.
- Visible gaps at the interlock when the window is closed. The meeting-rail weatherstrip has compressed past recovery, or the frame itself has racked out of square due to settling. On canal-front homes near the Lighthouse Point Marina, we’ve measured frame racking as high as 3/16 inch from seasonal humidity cycling in unconditioned Florida rooms.
- Water intrusion at the sill or stool during heavy rain. The weep holes are blocked with debris, or the sill pan was never flashed correctly during original construction. ES Windows sills have two weep channels - many installers only clear the primary and miss the secondary entirely.
- Condensation between the glass panes. The insulating glass unit seal has failed. ES Windows IGUs carry a 10-year warranty from the factory, but the labor to remove and reinstall the sash is not covered, and the warranty requires proof of original purchase.
- Difficulty locking or unlocking. The lock keeper has shifted with frame movement, or the cam has worn from repeated operation against a misaligned sash. We check this with a feeler gauge at three points along the meeting rail - anything over 1/8 inch indicates the frame needs shimming before hardware replacement will hold.

AfterReplacement Cost & What’s Included
| Scope | Price Range |
|---|---|
| Standard insert replacement (existing frame intact) | $340 - $520 per opening |
| Full-frame replacement with stucco repair | $620 - $780 per opening |
| IGU replacement only (sash removal/reinstall) | $180 - $290 per sash |
| Hardware-only swap (balances, locks, keepers) | $95 - $160 per window |
What drives the range: frame condition, stucco repair extent, whether the original install used proper sill pan flashing, and whether the opening requires impact-rated product per current Lighthouse Point building code. Every quote we write itemizes these line items separately - Haven Clause 1 - so the price you sign is the price on the final invoice. The 365-Day Done Right Promise covers labor and installation materials; manufacturer defects go through ES Windows directly, and we handle that paperwork as part of the job.
DIY or Call Us?

There is nothing dangerous about checking your own weep holes or reading the production code in the glass corner. What goes wrong is when an owner tries to remove an impact-rated sash without understanding the tilt-latch sequence - ES Windows 8000 Series sashes have a two-stage release that, done incorrectly, cracks the corner key or drops the sash on the sill. We’ve replaced three sashes in Lighthouse Point this year from exactly that mistake.
Full-frame replacement involves cutting stucco, verifying structural opening square to within 1/4 inch, and installing a sill pan that ties into the weather-resistive barrier. That is not a weekend project. Measure twice, write it down, then we talk price. Call (754) 600-8907 and we’ll schedule a survey that produces a written scope you keep, with no deposit required to book.
FAQs
In Lighthouse Point’s salt-air climate, a properly installed ES Windows unit typically performs 15-20 years for vinyl and 20-25 years for aluminum impact-rated product, assuming the weep system is cleared annually and the hardware is lubricated. Coastal exposure near the Intracoastal Waterway accelerates hardware corrosion by roughly 30 percent compared to inland Broward County. Call (754) 600-8907 for an exact quote on your specific opening - estimates are free.
Hardware failures, IGU seal failures, and weatherstrip degradation are all repairable without full replacement if the frame is square and the structural opening is intact. Frame rot, racking beyond 1/4 inch, or failed sill pan flashing require full replacement to meet current code. We document this with photos during survey and note the repairable versus replaceable condition on the written scope. Call (754) 600-8907 for an exact quote - estimates are free.
A standard insert replacement takes 2-3 hours per opening; full-frame replacement with stucco repair runs 4-6 hours. We schedule one opening per day for full-frame work to allow proper cure time on sealants and stucco patch. The written scope includes the daily schedule before any work starts. Call (754) 600-8907 to book a survey and receive your timeline in writing.
We carry ES Windows-compatible balances, tilt latches, interlock keepers, weatherstrip, and fasteners on every truck, plus select sash and frame components for the 8000 Series. Custom-size IGUs and Elite-series frames are ordered from ES Windows with a 10-14 day lead time; we track the order and schedule installation for the day after delivery. Call (754) 600-8907 to confirm availability for your specific model - estimates are free.
