ES Windows Bathroom Remodeling: The San Antonio Owner’s Guide
We stock and install ES Windows-compatible bathroom remodeling components throughout San Antonio, with most full bathroom remodels running between $9,000 and $28,000 depending on scope, materials, and whether we’re working around existing ES Windows framing or replacing it. Most owners discover they need this work when a window in the shower enclosure starts showing condensation between panes, the frame pulls away from tile, or the operable sash stops sealing against San Antonio’s humid summers. The window that once worked fine becomes a leak point, a mold risk, or simply an eye sore that drags down an otherwise functional bathroom.
Key Takeaways
- ES Windows bathroom work in San Antonio typically costs $9,000 – $28,000 installed.
- We match the specific frame depth and flange design ES Windows used in your build.
- Condensation and frame rot around bathroom windows are the two most common failure points we see across San Antonio homes.
- The written price comes before work starts, covering parts, labor, waterproofing, and cleanup.
Which ES Windows Models This Applies To
ES Windows are commonly used in mid- to high-end San Antonio builds, and the bathroom installations we service span three main series: their thermally broken aluminum lines in older custom homes, vinyl-framed double hungs in tract builds from the last fifteen years, and slider or awning units over tubs and shower surrounds. Identification is usually straightforward: look at the lower corner of the glass for an etched model code, or on the frame where the sash track meets the sill. We need that code, plus the rough opening measurement, before we order anything.
The gotcha with ES Windows in wet locations is the flange profile. ES uses a box flange on most residential lines, but some builder-grade installations went with a flat flange that requires a different waterproofing approach. If you have the flat flange and we treat it like a box flange, the corners will wick water into the wall cavity. We handle ES Windows bathroom work as an independent service provider, not as a factory affiliate, which means we source both OEM components and quality aftermarket equivalents. For frames themselves, OEM is usually the right call. For hardware, gaskets, and rollers on sliders, we often find aftermarket options that last longer in Texas humidity than the factory parts. We’ll tell you which one we’d pick and why, and the price difference is on the written quote before anything gets ordered.
Styles & brands we work with
Signs Your ES Windows Bathroom Remodeling Is Failing
- Condensation trapped between panes: The seal around the insulated glass unit has failed. That fog won’t wipe off because it’s inside the glass unit. In San Antonio, where a bathroom window deals with interior humidity from showers and exterior humidity from the climate, this is the most common failure we see. The fix is a glass unit replacement or, if the frame is compromised, a full window swap as part of the bathroom remodel.
- Frame pull-away at the tile line: The opening where window frame meets tile or drywall shows a gap that widens over time. Water is getting behind the waterproofing layer. Left alone in a San Antonio bathroom, this becomes mold inside the wall cavity within a season, not years.
- Sash won’t lock or seal: On double hungs and sliders, the hardware wears out or the frame shifts with house settling. The lock is a safety concern as much as it is an energy leak. When the sash won’t seat on the gasket, you’re losing conditioned air and letting swamp-humidity air into the room.
- Soft spots under the window paint: Tap the sill with a screwdriver handle. If it sounds dull or gives, the underlying wood is wet. This is a structural problem, not a cosmetic one. On a bathroom wall where the ES window sits too low to the shower, this is a design flaw as much as a part failure, and a remodel should address both.
- Visible rot on the exterior frame lip: The bottom corners of the frame or the exterior trim show cracking, bubbling, or darkening. Water has already penetrated and the frame is failing. In San Antonio, this often starts after a few seasons of hard late-summer rain that pummels the same corner of the house year after year, riding dry spells that bake the caulk until it separates.

AfterReplacement Cost & What’s Included
A full ES Windows bathroom remodeling project in San Antonio runs $9,000 to $28,000 installed. The spread is driven by whether we’re replacing one window while retiling around it, or gutting the entire bathroom and reworking the window opening as part of the plan. Materials run about 40 percent of the total; labor and waterproofing are the rest, and we never cut corners on the waterproofing layers behind the tile you can’t see.
| Scope | Installed Price Range |
|---|---|
| ES Windows unit replacement only, standard bathroom | $4,500 – $8,500 |
| Small bathroom remodel with ES Windows work | $9,000 – $12,000 |
| Full bathroom remodel, custom ES Windows framing | $12,000 – $28,000 |
| Tub-to-shower conversion with ES window relocation | $3,500 – $10,000 |
Every quotation includes the window or parts, all trim, waterproofing membrane, tile and grout, disposal of the old material, and the finished cleanup. No change orders, no surprise invoices.

DIY or Call Us?
You can safely check whether the window operates, whether the weep holes are clear, and whether water pools on the sill after a shower. That’s about where the safe DIY list ends. Window removal in a bathroom means breaking the waterproofing seal, and if you miss a single point where water can travel, you’ve created a hidden mold condition inside the wall. The water damage from a poorly reinstalled window in a San Antonio bathroom runs into the thousands to remediate, and insurance doesn’t always cover DIY mistakes.
It’s also worth being straight about the safety risk: glass removal near a shower enclosure often means working at awkward heights on wet surfaces, and a cracked pane in a wet bathroom is a serious cut hazard. Isaac Pruett and his crew handle these jobs with the right tools and the right containment. Call (254) 269-5071 and we’ll set up a time to look at the window, take measurements, and give you a written price before any work is scheduled.
FAQs
Fifteen to twenty-five years is realistic for an ES Windows unit in a San Antonio bathroom, though the seal on the glass unit often fails five to ten years earlier in west-facing rooms that catch full afternoon sun. Call (254) 269-5071 and we’ll tell you if the window you have is worth saving or if replacement makes more sense.
The glass unit, hardware, and gaskets can usually be replaced individually if the frame is still solid, which saves real money versus a full window swap. But if the frame shows rot or the flange has separated, a repair just delays the inevitable and lets more water into the wall. We’ll give you a straight answer during the inspection, not a sales pitch.
One day for a standard ES Windows unit swap that doesn’t require tile work around the opening. When we’re reworking the waterproofing, adding new tile, or doing a full remodel, the project runs three days to two weeks depending on scope. The written quote includes the schedule before you commit.
We stock common hardware, gaskets, and rollers for ES Windows bathroom units on our trucks and can order custom glass units and full frames with a manufacturer lead time of two to four weeks. We also stock compatible materials from KraftMaid, Cambria, and Silestone where the project involves cabinetry or countertops. Call us and we’ll tell you whether you’re a same-week fix or a custom-order job.
Know who’s coming, know what it costs, know it’s covered, that’s the whole job before the job starts. Call (254) 269-5071 to schedule your free estimate, and we’ll have the price in writing before any work begins.
