ES Windows Bathroom Remodeling: The San Antonio Owner’s Guide
ES Windows bathroom remodeling in San Antonio typically runs $9,000 to $28,000 installed, depending on how much of the existing frame and waterproofing needs to be rebuilt around the window opening. We stock and install ES Windows-compatible trim kits, sill pans, and flashing on our trucks, so most callouts turn into a written quote the same day. Most owners discover the problem the hard way: a soft spot in the drywall below the window, water staining on the sill, or a window that suddenly won’t close square after years of San Antonio humidity working the frame.
Which ES Windows Models This Applies To
ES Windows makes a few distinct lines that show up in San Antonio bathrooms, and the part you need depends on which one you have. The ES vinyl single-hung and horizontal slider units are the most common in 1990s and early-2000s homes across the metro. Newer builds lean toward the ES aluminum-clad casement and awning windows, which use a different sill pan profile and a narrower trim reveal.
Here’s the compatibility gotcha most people miss: ES Windows changed their sill pan extrusion depth around 2012. If your house predates that, the off-the-shelf replacement pan sold at big-box stores won’t seat correctly against the nailing flange. We pull the model label off the upper sash or side jamb and measure the pan depth before we order anything, so you’re not paying for a part that rides home in the truck and still doesn’t fit. For most repairs, OEM ES Windows parts are the right call because the extrusion profiles are proprietary. For trim and exterior flashing, a quality aftermarket equivalent from a reputable millwork supplier holds up just as well and usually saves you 15 to 20 percent.
Styles & brands we work with
Signs Your ES Windows Bathroom Remodeling Is Failing
- Water staining on the drywall or sill below the window. This almost always means the sill pan flashing has failed or was never installed correctly. Water finds the path of least resistance, and in San Antonio’s humidity, that path is usually down the inside of the wall cavity.
- The window binds or won’t close square. Framing rot around the rough opening lets the header or king stud sag. The window itself is usually fine; the bones around it are the problem.
- Soft drywall or bubbling paint near the corners. That’s moisture wicking through the framing from a failed seal at the nailing flange. By the time the paint bubbles, the rot is often worse than the stain suggests.
- Condensation or moisture between the glass panes. The insulated glass unit seal has failed. That’s an IGU replacement, not a full window replacement, and it’s a factory-ordered part.
- Visible daylight or a gap at the exterior trim. Caulk has failed and the window is no longer sealed against the weather. It’s a small fix if caught early, a bigger one if water has been getting in for months.
Replacement Cost & What’s Included
Here’s what we tell San Antonio homeowners up front, because the price should not be a mystery:
- Full bathroom remodel with ES Windows replacement or restoration: $9,000 – $28,000, depending on shower footprint, tile scope, and how much framing repair the window opening needs.
- Window-only repair or IGU replacement within a remodel: typically $800 – $2,500 added to the project, depending on the ES Windows model and whether we’re ordering OEM glass or replacing the full sash.
The biggest cost drivers are framing repair, waterproofing rebuild around the opening, and whether you’re doing a full surround or just a shower pan and glass. Every quote we write in San Antonio includes the parts, labor, waterproofing, and waste disposal. We don’t add surprise line items at the end. The price we put in writing before work starts is the price you pay, and the 365-Day Done Right Promise covers the workmanship for a full year after we hand the room back to you.

You can safely check the exterior caulk joints, look for visible gaps in the trim, and feel for soft drywall around the window. That tells you whether you have a problem and roughly where it’s starting. What you should not do is pull the window or the surrounding drywall yourself on a bathroom exterior wall. You’ll be into the waterproofing layer before you know it, and a bad DIY flashing job behind an ES Windows unit means you’ll be rebuilding that wall again in three years. If the part you’re replacing touches the window flange, the sill pan, or the waterproofing membrane, call (432) 547-6806 and we’ll give you a written quote. Estimates are free.
FAQs
Expect 15 to 25 years from the window unit itself in San Antonio’s climate, but the flashing and waterproofing around it often fail sooner, especially on west-facing walls that take full afternoon sun. The window rarely fails first; the install around it does.
Often yes. If the frame is solid and only the IGU seal, the sash, or the sill pan flashing needs work, we repair it and keep the original window. We only recommend replacement when the framing around the opening is rotted or the window is too far gone to reseal reliably. Call (432) 547-6806 and we’ll tell you which camp yours falls into.
Most bathroom remodels with window work run two to four weeks in San Antonio, depending on how much framing and tile is involved and how long the waterproofing needs to cure. We give you a timeline in writing before we start, and the photo updates keep you posted on progress without you having to call.
We carry common ES Windows sill pans, flashing profiles, trim kits, and sash seals on the truck, so most repairs can be priced and started the same visit. Specialty parts like custom IGUs or proprietary aluminum extrusions get factory-ordered with a lead time we confirm in writing before you pay anything.
