ES Windows Window Replacement: The Wellington Owner’s Guide

ES Windows window replacement in Wellington typically runs between $450 and $1,200 per window installed, depending on the series, glass package, and whether the frame needs full replacement or just a sash swap. We stock common ES Windows-compatible replacement parts on our trucks and can complete most single-window jobs in one visit. Where homeowners usually catch a failing ES window first is in the master bedroom or the west-facing side of the house: the sash gets harder to lift, condensation forms inside the glass at sunrise, or the locking mechanism stops seating flush.

ES Windows are built in Miami and engineered for South Florida’s humidity and storm season. They’re a solid mid-to-upper tier line, but no window is immune to what Wellington’s climate does to hardware and seals over ten or fifteen years. The salt air that drifts in from the coast, combined with the daily UV load and summer afternoon downpours, works on rollers, balances, and weatherstripping in ways a window in Ohio never has to deal with. When we pull an ES window from a Wellington home that’s been in since the early 2010s, the failure is almost always predictable: worn nylon rollers on the sliding panels, a compromised glazing bead that let moisture into the insulated glass unit, or a lock that’s been forced past its travel one too many times.

TruePane Windows & Doors is an independent service provider. We are not affiliated with ES Windows, but we have installed and serviced their product line across Palm Beach County for years, and we know which parts interchange, which ones don’t, and where to source what we don’t carry.

Which ES Windows Models This Applies To

ES Windows produces two main residential lines you’ll see in Wellington homes: the ES Series (their standard residential offering, available in single-hung, horizontal roller, casement, and fixed configurations) and the ES Impact Series (laminated glass, heavier frames, built to Miami-Dade and Palm Beach County impact standards). The parts that fail on these two lines often look similar from a distance but are not interchangeable, and that matters when you’re pricing out a fix.

Before you call anyone, find the manufacturer label. On ES Windows, it’s usually a silver or white sticker on the inside edge of the frame, visible when you slide the sash open. The label will show the series, the glass thickness, and sometimes a manufacturing date code. If the sticker is gone (sun and humidity peel them after a decade), we can still identify the window by measuring the frame depth, the sash profile, and the glass thickness. That’s a measurement we take on-site, in front of you, with the window open, not something we guess at over the phone.

One compatibility gotcha we run into regularly in Wellington: the ES Series single-hung uses a spiral balance system that changed slightly around 2015. A balance cartridge from a pre-2015 window will not seat correctly in a newer frame, even if the window looks identical from six feet away. That’s why we always pull the sash and check the balance tube before we quote. Aftermarket parts exist for ES Windows and some are perfectly serviceable, but for balances and locking hardware we default to OEM or a direct-match equivalent. The savings on a no-name roller or lock assembly rarely survives a Wellington summer.

Signs Your ES Windows Window Replacement Is Failing

• Condensation or fog between the glass panes. This means the insulated glass unit’s seal has failed and the desiccant inside the spacer is saturated. It won’t dry out on its own. On an ES Window, this is a glass replacement, not a full frame replacement, and it’s the most common service call we get from Wellington homeowners.
• The sash is difficult to lift or feels like it’s fighting you. On ES single-hungs, this is usually a worn spiral balance or a binding shoe. On sliders, it’s nylon rollers that have flattened or cracked from years of heat cycling. Forcing the sash up increases the load on the frame and shortens the life of everything else.
• The lock or handle won’t seat or turns past its stop. ES window locks are cam-style and depend on precise alignment between the sash and the frame. After years of thermal expansion and settling, that alignment drifts. Sometimes it’s a simple adjustment. Sometimes the keep is worn and needs replacing. Left alone, a window that doesn’t lock properly is a security issue and an air leak.
• Daylight visible at the frame corners or a draft you can feel with the back of your hand. This points to failing weatherstripping or a frame that has shifted out of square. Weatherstripping is cheap. A frame out of square is not. Either way, you’ll want it diagnosed before hurricane season, not after.
• Water staining on the interior sill or wall below the window. On an impact window, a leaking frame is often a failed sealant joint where the frame meets the opening, not a failure of the window itself. We see this in Wellington homes built in the early 2000s, where the original caulk has given up after twenty years of UV exposure. The fix is a proper bead of commercial-grade sealant, not a tube of hardware-store caulk over the old layer.

Replacement Cost & What’s Included

Installed ES Windows window replacement in Wellington runs on a range, and it’s a range worth understanding before you sign anything. A single insulated glass unit replacement for an ES Series window starts around $450 and goes up depending on glass size, Low-E coating, and whether it’s impact-rated. A full sash replacement with new balances and hardware lands between $600 and $850. A complete tear-out and replacement of an ES impact window, frame and all, starts around $1,000 and tops out around $1,200 for standard residential sizes.

What drives the price is the glass. ES Windows uses several glass packages, and the difference between a clear double-pane unit and a Low-E, argon-filled, impact-laminated unit is real money. We quote the glass package that matches what’s already in your opening, because mixing glass types on the same elevation creates a color difference you’ll notice every time you look at the wall. Every quote from TruePane includes the part, the labor, the cleanup, and the warranty registration paperwork, written out line by line.

Our workmanship is guaranteed for 90 days under the Done Right Promise. Both manufacturer warranty layers get registered in writing before our truck leaves your driveway. No vague verbal assurances, no fine print that covers neither. That’s The Keystone Standard, and it applies to every ES Windows part we install.

DIY or Call Us?

There are things a Wellington homeowner can safely check before making a call. You can clean the tracks. You can inspect the weatherstripping for visible tears. You can confirm whether the condensation is inside the room, on the outside of the glass, or between the panes. If it’s inside the room or outside, that’s humidity or dew, not a seal failure. If it’s between the panes, the IGU is done.

What we don’t recommend is pulling an ES Window yourself. The sashes are heavy, especially impact glass, and the spiral balance assemblies are under tension. One that’s been in a Wellington window for ten years can release suddenly when you remove the sash. The same goes for replacing lock hardware: the alignment matters, and if it’s wrong, you’ve turned a $50 lock part into a $700 sash replacement. That’s the kind of thing Dale Kessler has seen more times than he cares to count. If you’re not sure what you’re looking at, call (561) 349-4826 and describe it. We’ll tell you honestly whether it’s worth a service call.
