ES Windows Bathroom Remodeling: The Miami Owner’s Guide
If you have ES Windows in your Miami bathroom and they’re fogging, leaking, or the frames have started to corrode, we stock the replacement hardware and can handle the full bathroom remodel around them. A complete ES Windows bathroom remodeling project in Miami typically runs $10,620 to $33,040, depending on how many windows you’re replacing and what else in the bathroom needs work. Most owners discover the problem the same way: a window that won’t open after a humid summer, or condensation trapped between panes that won’t go away no matter how long you run the fan.
ES Windows are popular in Florida because they’re built for hurricane zones, but the salt air and humidity in neighborhoods like Brickell, Coral Gables, and Coconut Grove put real stress on the frames and seals over time. When those seals fail, the window loses its insulating gas and you start seeing moisture where it shouldn’t be. That’s the point where you’re not just looking at a window replacement anymore – you’re looking at potential water damage to the drywall, the sill, and whatever’s behind it.
Which ES Windows Models This Applies To
ES Windows makes a few different product lines, and the parts aren’t always interchangeable. The most common models we see in Miami bathrooms are the ES700 series single-hung and the ES Series 2 horizontal sliders. Both use a 5/8-inch insulated glass unit, but the frame depth and the balance system are different between them. If you try to swap hardware from one series into the other, the window won’t seal correctly and you’ll be back in the same spot within a year.
Here’s the gotcha most people don’t know: ES Windows stamps the model number on the inside of the frame, not on the glass. You have to open the window and look at the top of the lower sash rail to find it. If the stamp is worn off, measure the visible glass thickness – ES700 units are 5/8-inch thick, and Series 2 sliders are often 3/4-inch in newer builds. That measurement alone tells us what we’re working with before we even quote the job.
When it comes to replacement parts, you’ve got two paths. OEM ES Windows parts come through their Florida distribution network and cost more, but they match the original warranty and the exact frame color. Quality aftermarket equivalents – mostly the balances, the tilt latches, and the weatherstripping – run about 30 to 40 percent cheaper and hold up just as well in our experience. We’ll give you a written price for both options on the estimate, so you can decide which one makes sense for a window you might be replacing anyway during the remodel.
We also stock parts for KraftMaid cabinetry, Cambria surfaces, and Silestone countertops if your bathroom project expands beyond the windows. Sawyer Remodel Miami is an independent contractor, not affiliated with ES Windows directly – which means we can be honest about what’s worth fixing and what’s worth replacing without a brand rep breathing down our necks.

Signs Your ES Windows Bathroom Remodeling Is Failing
- Condensation between the glass panes. This means the seal has failed and the argon or krypton gas has escaped. Once that happens, the window’s insulating value drops to almost nothing and the condensation will only get worse, especially after hot showers.
- Difficulty opening or closing the sash. The balance springs inside the frame wear out, particularly in bathrooms where humidity causes the steel components to corrode faster. If you have to shoulder the window open, the balances are done.
- Visible corrosion or pitting on the aluminum frame. Salt air in Miami neighborhoods closer to the coast accelerates this. Once the frame starts pitting, water finds its way behind the frame and into the rough opening, which means drywall damage next.
- Soft or stained drywall around the window. That’s not a window problem anymore – that’s a water intrusion problem. The window has been leaking long enough that the surrounding wall is compromised, and the remodel scope just expanded.
- The window no longer locks or latches securely. For a hurricane-rated window, a failed lock is a security issue and a code issue. Miami-Dade has strict requirements, and a bathroom window that won’t latch won’t pass inspection if you’re pulling permits for the remodel anyway.

AfterReplacement Cost & What’s Included
In Miami, a full ES Windows bathroom remodel with window replacement typically lands between $10,620 and $33,040. The spread comes down to a few things: how many windows you’re replacing, whether the surrounding drywall and waterproofing need rebuilding, and whether you’re doing just the window area or a full bathroom overhaul including shower, vanity, and tile.
Here’s how the numbers break down:
- Single ES Windows replacement (OEM parts, labor included): $1,180-$2,950 per window depending on size and series
- Full bathroom remodel with window replacement: $10,620-$33,040
- Walk-in shower installation: $5,310-$14,160
- Tub-to-shower conversion: $4,130-$11,800
- Bathroom vanity installation: $945-$3,540
Every estimate from Sawyer Remodel Miami comes with a written price before work starts, so the number you approve is the number on the final invoice. Our 365-Day Done Right Promise covers the workmanship for a full year after the project closes – if something’s not right, we make it right, in writing. No change orders, no surprise line items, no “oh, we found something” at the end.
DIY or Call Us?
There’s an honest split here. You can clean the tracks, check the weep holes for blockage, and run a bead of silicone around the exterior frame to buy yourself some time before the remodel. Those are reasonable homeowner tasks that don’t require special tools or knowledge. What you should not do is try to replace the balance springs or the insulated glass unit yourself. The balances are under tension, and a 5/8-inch IGU weighs more than you expect when it’s coming out of a frame at shoulder height. Combine that with Miami’s humidity and a tile floor, and it’s a broken-glass injury waiting to happen.
If the window is fogged, corroded, or leaking into the wall, call (850) 801-8046. We’ll send a background-checked, uniformed technician with the right parts on the truck, and you’ll get a live arrival time before we show up. No four-hour windows, no chasing a contractor. Luca Romano and the crew have been running jobs in Miami for years, and good work doesn’t need a sales pitch.
FAQs
In Miami’s heat and humidity, ES Windows bathroom units typically last 12 to 18 years before the seals or balances need attention. Coastal salt air shortens that to around 10 to 14 years for homes within a few miles of the water. Most failures we see are seal failures and balance corrosion, not the frame itself. Call (850) 801-8046 to schedule a free estimate and we’ll tell you exactly what you’re working with.
In most cases, the glass unit can be replaced without replacing the entire window frame – we remove the failed IGU and install a new one while keeping your existing frame. If the frame is corroded or leaking, replacing just the glass won’t solve the water problem, and a full replacement is the smarter fix. Call us and we’ll give you a straight answer on which applies to your window.
For a single window replacement, the swap usually takes one day including cleanup. A full bathroom remodel with window replacement typically runs two to four weeks depending on scope, tile work, and whether permits need to be pulled. Before we start, you’ll get a written timeline along with the written price, and we’ll keep you updated with before-and-after photos as the job progresses.
We stock the most common ES Windows replacement parts on our service trucks – balances, tilt latches, weatherstripping, and standard-sized IGUs for the ES700 and Series 2 lines. If your window needs a custom-size glass unit, that’s typically a five-to-seven-day lead time through the Florida distribution network. Call (850) 801-8046 and we’ll check our stock while you’re on the phone.
