ES Windows Bathroom Remodeling: The Miami Owner’s Guide
If you have ES Windows in a Miami bathroom that’s showing its age, expect to pay between $10,620 and $33,040 for a full bathroom remodel that respects and works around those existing window openings. We can typically start within two weeks, and we’ll give you a written price before any work begins. Most Miami homeowners call us because they notice moisture damage around the ES window frame, fogging between panes, or tile grout failing near the opening – all signs that the window and the bathroom around it have stopped working together the way they should.

Which ES Windows Models This Applies To

ES Windows builds impact-rated aluminum and vinyl lines commonly found in Miami condos, townhomes, and single-family homes built after the 1990s. The two series we see most often in bathrooms are the ES Windows ESW-400 (aluminum, single-hung) and the ESW-700 (impact-rated casement and fixed units). Here’s the compatibility gotcha most people miss: ES Windows uses a proprietary frame depth on their impact units, which means the rough opening dimensions don’t always match what a standard window replacement assumes. If you’re remodeling a bathroom and want to keep or replace the ES window, we measure the actual frame pocket, not the glass, before quoting. On the OEM versus aftermarket question, we’ve installed both. For impact-rated ES units within ten miles of the coast, we recommend sticking with ES Windows OEM sashes and hardware – the aftermarket equivalents often don’t carry the Miami-Dade NOA (Notice of Acceptance) paperwork your insurance company will want to see.
We also stock and install parts for KraftMaid cabinetry, Cambria and Silestone surfaces when remodeling bathrooms with ES Windows, so countertop and vanity work doesn’t require a second contractor.

Signs Your ES Windows Bathroom Remodeling Is Failing
- Fogging or condensation between the glass panes. The seal between the insulated glass unit has failed, which means the ES window has lost its insulating ability. In Miami’s humidity, this gets worse within a season, not better.
- Water staining on drywall or baseboard below the window. The window’s weep holes are clogged or the flashing was never done correctly at install. We see this in Miami bathrooms where shower steam has nowhere to go, so moisture gets pushed into the wall cavity.
- Operable window that’s hard to open, sticks, or drops when you let go. ES spiral balances wear out faster in coastal air, but often the issue is that tile work or new framing has put pressure on the window frame.
- Black mold or mildew on the interior frame or surrounding grout. In a Miami bathroom, this usually means there’s no exhaust fan or the fan is undersized for the room, and the ES window was the only ventilation. Remodeling should address both together.
- Visible cracks at the corners of the tile around the window opening. Water has gotten behind the tile and swelled the substrate. If you wait until the tile falls off, the repair cost doubles.

AfterReplacement Cost & What’s Included

Here’s what a bathroom remodel involving ES Windows costs in Miami, based on the work we actually do:
| Scope | Miami Installed Price |
|---|---|
| Full bathroom remodel (window stays, full interior demo and rebuild) | $10,620 – $33,040 |
| Small bathroom remodel (toilet room, single vanity, ES window remains) | $5,900 – $14,160 |
| Walk-in shower installation with window work | $5,310 – $14,160 |
| ES window replacement only (while wall is open during remodel) | $944 – $2,950 per opening |
Those numbers include parts, labor, debris hauling, and the written guarantee. What drives the range is the condition of the wall framing once we open it, whether the ES window needs to be re-flashed or replaced entirely, and whether you’re moving plumbing. We give you a written line-item price before the first tool comes off the truck – and that price doesn’t move unless you change the scope.
The work is covered by our 365-Day Done Right Promise: if anything isn’t right within a year of completion, we make it right at no cost to you, no dispute process, no conditions.
DIY or Call Us?
You can safely do a few things to diagnose an ES window problem in your Miami bathroom. Check for standing water in the sill track, clear the weep holes, and run the exhaust fan during and after showers. But if the issue involves removing tile, replacing a window, or working inside the wall cavity, do not open that wall yourself. ES impact windows are heavy, and a dropped unit on the second floor of a Coral Gables townhome is exactly the kind of mistake that costs more to fix than the original job would have cost to do right. Call us at (850) 780-8123. Isaac Pruett will come out, read the job, and give you a straight number with no padding.

FAQs

In Miami’s salt air and humidity, an ES Windows aluminum unit will last 20 to 30 years before needing replacement, but the seals on the insulated glass often fail in 8 to 12 years. If you’re remodeling a bathroom anyway, replacing the glass unit while the wall is open is the cheapest way to do it.
Yes, if the frame is sound and the issue is the glass, the balance, or the hardware, we can repair it. If the frame is corroded or the wall framing behind it is rotted, replacement is cheaper in the long run. Call (850) 780-8123 and we’ll give you an honest answer either way.
A full bathroom remodel takes two to four weeks depending on whether we’re moving plumbing or just rebuilding in place. Replacing the ES window itself adds one day to the schedule. We’ll give you a written schedule with your written price.
We keep common ES Windows balances, sashes, and hardware on hand, and we order full replacement units directly from ES Windows distributors in Miami-Dade, which usually means the unit is in our warehouse within five business days. Call (850) 780-8123 for an exact lead time on your series.
