ES Windows Bathroom Remodeling: The Jacksonville Owner’s Guide
ES Windows bathroom remodeling in Jacksonville typically runs $9,000 to $28,000 installed, depending on whether you’re replacing a single venting window above a tub or rebuilding the entire wet wall with a new ES Windows unit framed, flashed, and trimmed. We match the window to your existing ES Windows series, handle the demo and waterproofing, and leave the bathroom dry and code-compliant. Most owners discover the problem when they see condensation between the panes, feel a draft near the sill, or notice the window won’t lock closed after a few humid Jacksonville summers.
The interesting thing about ES Windows in Florida bathrooms is that the failure usually isn’t the glass. It’s the frame seal or the flashing around it. The window itself may still look fine from inside, but water is getting behind the tile, into the rough opening, and working its way down. By the time you see a soft spot on the drywall below the window, the repair is no longer just a window swap. That’s why we always start a bathroom window job by pulling the trim and looking at the framing behind it before we quote a final number. You’ll get a written price before any work starts, and that price holds unless we both agree in writing to change it.
Which ES Windows Models This Applies To

ES Windows manufactures several residential lines, and bathroom compatibility depends on the series stamped on the glass or frame edge. The ES 6000 series is the most common in single-family homes around Jacksonville – typically a white vinyl or aluminum-clad frame with a standard 2-5/8″ frame depth. The ES 8000 series is a step up in energy rating, and we see it often in newer construction in Nocatee and Bartram Park. The ES 3000 series shows up in some older Jacksonville Beach condos where the HOA approved a mid-grade vinyl replacement.
Here’s the compatibility gotcha most homeowners don’t know: the glass seal failure that looks like a simple pane replacement is almost always a full-sash or full-frame replacement on ES units. You can’t just re-seal the insulated glass unit in the field and have it hold up in Florida humidity. If the sash is intact and square, we can often replace just the sash. If the frame is pitted, soft at the corners, or the weep holes are clogged with years of Jacksonville pollen and mildew, the whole frame comes out. And if the original installer set the window without proper sill flashing, the new unit goes back in with a sloped sill pan, backer rod, and taped seams – the way it should have been done the first time.
We use OEM ES Windows parts where the frame is still under manufacturer warranty, and quality aftermarket sashes and balances when it’s not. The aftermarket glass packs we use carry the same insulating gas fill and low-E coating spec as the original, and they come with a 10-year seal warranty. If you’re unsure which series you have, look for the etch in the lower corner of the glass – it lists the series code, the date of manufacture, and the IGCC certification number. A photo of that etch sent to us before the first visit saves everyone time.
Styles & brands we work with







Signs Your ES Windows Bathroom Remodeling Is Failing
- Condensation or fog between the panes. The insulated glass seal has failed, and Jacksonville’s humidity is now living inside the window. This doesn’t reverse itself, and it gets worse with every hot shower. The fix is sash or glass pack replacement, not a wipe-down.
- Soft drywall or peeling paint below the window. Water is entering the rough opening, most often at the sill or the top corners. The window may look fine, but the flashing behind it has failed. Ignoring this turns a $3,000 window job into a $15,000 wall and tile rebuild.
- The window won’t lock, or the sash binds when you open it. In a bathroom, this is typically a combination of humidity swelling and failing balance hardware. On ES units, the spiral balances or block-and-tackle assemblies wear out, and the sash sits unevenly in the track. Forcing it closed often cracks the frame at the lock point.
- Drafts you can feel when standing at the sink. The weatherstripping has compressed or the frame has shifted slightly. In a bathroom, this is a comfort issue and a mold precursor, because warm moist air meets cool glass and condenses inside the wall cavity.
- Black staining at the lower corners of the frame or on the caulk line. That’s mildew working its way from the weep holes inward. The rough opening has been damp long enough for organic growth. We treat the opening with a mold-inhibiting primer before the new window goes in, and we check the sill slope so water drains outward instead of pooling.

AfterReplacement Cost & What’s Included

In Jacksonville, an ES Windows bathroom window replacement with trim, flashing, and finish work runs between $9,000 and $28,000 depending on scope. A single sash replacement above a fiberglass tub surround tends to land at the lower end of that range. A full frame replacement with tile repair, waterproofing behind the wet wall, and new casing around the window runs higher. If the framing behind the window has water damage, the price climbs because we’re rebuilding the rough opening, not just swapping a unit.
Here’s what that price includes, broken out so you can see it:
- Window unit: $800 to $3,200 depending on series, size, and glass package (single sash vs full frame).
- Demo and disposal: $400 to $1,200, including protected haul-out through the house with drop cloths laid from the bathroom to the door.
- Flashing, pan, and waterproofing: $600 to $2,500, using Schluter membrane and a sloped sill pan rated for wet areas.
- Tile repair and trim: $1,500 to $9,000, depending on how much surrounding tile must be removed to reach sound framing and what it costs to match the existing tile pattern.
- Labor: $3,000 to $9,000 for the crew, including the time to protect the floors, mask off the work area, and clean up before we leave.
Every project comes with a written price before any work starts – listed by line item, materials by name, labor by stage. There are no allowance line items that quietly grow. The 365-Day Done Right Promise covers the finished work: if the window leaks, binds, or fogs within a year of installation, we make it right. That’s in writing.
DIY or Call Us?
There are two things you can safely check yourself. First, confirm the weld seam on the frame corners hasn’t split – run a finger along the interior corner joints. Second, check that the weep holes on the exterior bottom edge are clear of dirt and caulk. Clogged weeps are a common and easily fixed cause of minor sill dampness. If the weeps are clear and the frame seams are intact but you still see fogging or water staining, the problem is beyond a homeowner fix.
Here’s where DIY goes wrong on a bathroom window: the waterproofing. A window in a wet wall has to be installed differently than one in a living room wall. It needs a continuous sill pan, taped corners, and a back dam so water that gets behind the tile drains outward, not into the stud cavity. A homeowner who replaces the window and reuses the old caulk line has not fixed the water entry – they’ve just hidden it behind a new frame. The same goes for tile removal around the window. Breaking tile without cutting the grout lines first often cracks the surrounding tiles, and now you’re retiling half the shower. And if there’s any chance the wall cavity has been wet for months, you want a professional to open it and look. Mold inside a wall is not a weekend project.

FAQs

Expect 15 to 20 years from the frame and 10 to 15 from the insulated glass seal in Jacksonville’s coastal humidity. Windows that face direct afternoon sun on the west side of the house tend to lose their seals sooner. If your window is past year 12 and showing fog, replacement is the honest answer, not repair. Call (904) 643-6243 and we’ll give you a straight read on what’s left in it.
If the frame is square and the sash moves freely, we can often replace just the glass pack or the balance hardware. If the frame corners are split, the sills are soft, or water has been entering the rough opening, a full replacement is cheaper in the long run. We’ll show you the framing in a photo before we ask you to spend anything.
A single-sash swap takes a day. A full frame replacement with tile repair and waterproofing typically runs three to five days, including drying time for the membrane and grout. We’ll name the day the crew arrives and the day we’re done, and we protect the floors with drop cloths from the bathroom to the front door while we work.
We keep common ES 6000 and 8000 series sashes, balances, and weatherstripping in stock, and we order anything outside that spec directly from the manufacturer or our aftermarket supplier with a 10-year seal warranty. We’ll know what you need after we see the glass etch and the frame condition. Call (904) 643-6243 and we’ll walk you through it.
