ES Windows Window Replacement: The Naples Owner’s Guide
We stock and install ES Windows-compatible replacement parts across Naples, with most window replacement work running $340 to $1,100 installed depending on the sash, balance, or hardware involved. If you’ve got a window that won’t stay up, a crank that spins without moving the sash, or a latch that no longer seals against summer humidity, we can usually identify the part on the first visit and have it set the same day. Most Naples owners discover the failure the hard way, in August, when an awning window that used to close tight now lets in the afternoon rain or the Gulf breeze rattles a loose sash like a snare drum.

TruePane Windows & Doors is an independent service provider, not affiliated with ES Windows. We carry OEM and quality aftermarket parts that match ES Windows frame depths and hardware spacing, and we register the work under our 90-Day Done Right Promise so the repair is not a gamble.
Key takeaways:
- We match ES Windows parts by series, frame depth, and hardware spacing, not by guesswork.
- Most single-sash replacements are quoted on the spot and installed the same visit.
- Both warranty layers are registered in writing before our truck leaves your driveway.
Which ES Windows Models This Applies To
ES Windows builds several series that show up regularly in Naples homes, from older single-hung frames along the older neighborhoods east of 41 to casement and awning units in newer construction out by the Vineyards and Pelican Bay. The part that fails depends heavily on the series. The ES65 and ES70 lines used different balance systems, and a shoe that fits one will bind in the other. We verify against the label etched on the frame or the spacer bar, and when that label is gone from years of salt air, we measure the glass thickness and the sash channel depth before quoting anything.
Here is the compatibility gotcha that catches people: ES Windows hardware spacing changed between production years, not just between series. A sash lock that fits a 2012 ES70 may not line up on a 2016 unit even though both say ES70 on the sticker. That is why we bring a measured set of locks, keepers, and pivots on the truck rather than ordering blind from a part number. For balances, OEM is worth the cost on newer units because the tension curve matches the sash weight. On older units where OEM is discontinued, we source aftermarket balances with matching tension ranges and state plainly what you are buying before we install it.
Signs Your ES Windows Window Replacement Is Failing
- The sash drops or will not stay up. On single-hung units this almost always means the block-and-tackle balance has lost tension or the shoe has cracked. We see this most on the west-facing elevations in Naples where afternoon sun bakes the hardware through the glass.
- The crank turns but the sash barely moves. That is a stripped operator gear or a worn hinge arm on casement and awning windows. Forcing the crank past the resistance just rounds the splines further.
- The lock does not draw the sash tight. A keeper that is worn flat or a lock body with a stretched spring means the window seals but does not seal. You notice it as draft in January and mildew smell in July.
- Condensation between the panes. The seal has failed and the gas is gone. The hardware may still work, but the glass no longer insulates and the fog will not wipe off from either side.
- The sash binds or scrapes when opening. That is a bent hinge or a shoe that has jumped its track. Run it anyway and the frame will score, turning a parts swap into a frame repair.
Replacement Cost & What’s Included
In Naples, ES Windows window replacement parts land in these ranges installed:
- Spiral or block-and-tackle balance replacement: $180 to $320 per sash
- Crank operator and hinge set for casement or awning: $260 to $480 per window
- Sash lock and keeper replacement: $95 to $160
- Glass unit replacement on a failing ES Windows pane (seal failure): $340 to $1,100 depending on glass spec and size
- Full sash replacement including glass and hardware: $450 to $1,100 per sash
The spread comes down to two things: whether your ES Windows series takes OEM or aftermarket parts, and whether the glass is standard clear or impact-rated with low-E coatings. Most Naples units we replace are impact glass, which costs more but is code-required in much of coastal Collier County for new and replacement work. Every quote we write is line-item on paper: the part, the labor, the disposal. You will not find a surprise charge on the invoice. We pull permits when the job requires them and register the manufacturer warranty plus our own workmanship warranty before we leave.
DIY or Call Us?
You can safely check the label on your frame, note whether the sash is single-hung or casement, and take a photo of the failing hardware. That helps us arrive prepared. What you should not do is disassemble a tensioned balance or try to lift a casement sash off a hinge arm alone. The balance holds stored force, and when it releases wrong it takes fingers with it. Dale Kessler has read enough rough openings in Naples to know that a window that looks simple has about six ways to go sideways in a salt-air climate, and a stripped operator is the least of them. If the pane is not true, the job is not done, and we would rather set it once than unset your mistake twice. Call (239) 326-9942 and we will look at it properly.
FAQs
Plan on 8 to 14 years for balances and hardware in coastal Naples, less on west-facing windows where salt and sun work together. Glass units with failed seals typically show fog between years 10 and 20. Call (239) 326-9942 and we will tell you if your part is near end of life or worth replacing alone.
Some components, like a keeper that is out of alignment, can be corrected without new parts. But a cracked balance shoe, stripped gear, or failed seal is a replacement job, and patching it just guarantees a second visit. We quote the repair path only when it will actually hold.
Most single-sash part replacements take 45 to 90 minutes once we have the correct part in hand. We carry common ES Windows balance and hardware parts on the truck, so the first visit usually finishes the job.
Yes. We keep common ES Windows balances, locks, keepers, operators, and hinge arms on hand for Naples service calls, and we source OEM or matching aftermarket parts for discontinued series as needed. If it is not right when we leave, we come back until it is.
