ES Windows Bathroom Remodeling: The San Antonio Owner’s Guide

If you have an ES Windows bathroom window or enclosure that has failed, warped, leaked, or fogged, a bathroom remodel in San Antonio typically runs $9,000 to $28,000 when the window work is bundled with surrounding tile, waterproofing, and fixture replacement. We stock ES Windows-compatible components and can usually match your existing frame or recommend a correct retrofit within one visit. The fix itself is rarely “just the window” – in San Antonio’s humidity and hard-water environment, the window failure is usually the first visible sign that the shower surround, sill flashing, or waterproofing behind it has also aged past its useful life. Here is what we have learned installing and repairing ES Windows-specific bathroom assemblies across neighborhoods from Alamo Heights to Stone Oak to Helotes.

Key Takeaways

• Bathroom remodels with ES Windows replacements in San Antonio run $9,000 – $28,000 depending on shower scope, waterproofing method, and fixture grade.
• Our written price comes before any work starts, and it does not change after demo day.
• ES Windows bathroom units are often custom-sized – measuring the glass, not the rough opening, is where most DIY orders go wrong.
• We sit down with you, go through your model and measurements, and give you a line-item price you can keep.

Which ES Windows Models This Applies To

ES Windows builds residential aluminum and vinyl window lines that turn up regularly in San Antonio bathrooms – awning units, horizontal sliders, and fixed picture windows above tubs and in shower enclosures. The bathroom-specific versions are most often the ES Windows 3000 and 5000 series, with the difference coming down to frame depth and glass package. The 3000 series sits shallower in the wall and is more common in older San Antonio ranch homes where the bathroom wall cavity is a true 2×4. The 5000 series has a deeper frame that works better in 2×6 exterior walls and newer construction.

Here is the compatibility gotcha that catches people: ES Windows bathroom units are frequently custom-ordered in non-standard sizes. The label on the head of the frame will show a factory order number, but the width and height stamped on it are the frame dimensions, not the glass dimensions. If you order a replacement sash or glazing pack from a generic supplier using the frame numbers, the glass will arrive too large. We measure the visible glass and the mullion width before we order anything. For older ES Windows units where the factory label is worn off, we take three measurements – left, center, and right – because San Antonio slab homes settle and the frame might be true on one side and 1/8 inch off on the other.

On the OEM-versus-aftermarket question: for ES Windows frames in good structural shape, a quality aftermarket glazing package from a San Antonio glass supplier is often the better value – the insulated glass unit is the part that fails, not the aluminum frame. If the frame itself is pitted or the weep holes have corroded shut, we recommend replacing the full window, and that is when matching the series matters for the waterproofing integration with the shower surround.

Signs Your ES Windows Bathroom Remodeling Is Failing

• Fogging between the glass panes. The seal on the insulated glass unit has failed and San Antonio humidity has gotten inside. Once the argon or krypton gas escapes, the window loses its insulating value and the fog never clears on its own.
• Condensation on the inside of the window that beads and drips. This usually means the bathroom exhaust fan is underpowered or the window’s weep system is blocked. The moisture is not draining, and over time it rots the sill and the drywall below.
• White chalky residue or pitting on the aluminum frame. San Antonio hard water will etch anodized aluminum over years of shower steam. Once the anodized layer is gone, the frame corrodes, fasteners seize, and the window binds when you try to open it.
• Soft drywall or peeling paint beneath the window. This is the serious one. Water is getting past the sill flashing or the shower surround waterproofing. By the time you see this, the repair is a remodel, not a window swap – and delaying it spreads mold into the wall cavity.
• You can feel air moving around the frame when the window is closed. The weatherstripping has flattened or the frame has shifted. In a bathroom, that air leak pulls conditioned air out of the house and drags humid outside air across the glass, which feeds condensation and mold on the frame.

Replacement Cost & What’s Included

A bathroom remodel that includes an ES Windows window replacement in San Antonio typically runs $9,000 to $28,000. The window itself is a small part of that line item – on most jobs it is $700 to $2,400 including the glazing package and installation, depending on size and whether we are replacing a sash or the entire frame. The rest of the range comes from the shower waterproofing method, tile selection, plumbing fixture grade, and whether we are relocating or enlarging the window opening, which means reframing and permit work.

Here is how the numbers break down in San Antonio:

• Small bathroom remodel with one ES Windows window replacement: $9,000 – $12,000 (new fixtures, standard tile, existing layout, one window swapped)
• Full bathroom remodel with tub-to-shower conversion and window work: $12,000 – $20,000 (Schluter waterproofing, tile surround, glass enclosure, window replacement)
• Full bathroom remodel with window relocation or enlargement plus custom tile and premium fixtures: $20,000 – $28,000 (reframing the opening, custom shower, Kohler or Grohe fixtures, heated floor if desired)

Every quote includes the written line-item price, the window material, waterproofing, tile, fixtures, the permit, and the clean-up – shoe covers at the door, drop cloths on the floor, and a photo of the finished clean-up before our crew leaves. We do not add line items after demo day. The number you sign is the number you pay.
