ES Windows Bathroom Remodeling: The Los Angeles Owner’s Guide

If you have ES Windows products in your bathroom and one has failed, cracked, or started leaking, we can match the replacement and handle the full remodel around it. A bathroom remodel that includes ES Windows-compatible replacement work in Los Angeles typically runs $10,620 – $33,040, depending on how much of the room we’re rebuilding. Most owners discover the problem the same way: a fogged double pane, water staining on the sill after rain, or a corner that won’t open without real muscle. We stock the common ES Windows hardware on our trucks, and Trevor Nash grew up in Reseda watching those older Valley ranch houses get rebuilt, so we know how LA weather treats these units.

Which ES Windows Models This Applies To

ES Windows makes a few distinct lines that show up in Los Angeles bathrooms, and the part you need depends on which one you have. The ES Windows Series 700 and Series 850 are the most common in bathroom applications, with frame depths between 3¼ and 4½ inches. The Series 700 uses a narrower aluminum profile and is frequent in older mid-century and 1960s-80s bathrooms across the San Fernando Valley and Westside. The Series 850 is a thermally broken frame, which matters in a steamy bathroom because it resists condensation better than the 700.

To identify yours, look at the spacer bar inside the glass (the metal strip between the two panes). ES Windows stamps the spacer with a two-letter date code and the series number. If the stamp is worn off, measure the visible frame depth from the interior face of the window to the exterior edge. 3¼ to 3½ inches usually means Series 700. Closer to 4½ means Series 850. That measurement alone tells us which gaskets, rollers, and latches you need without a second trip. We’re an independent Los Angeles remodeling contractor, not an ES Windows dealer, so we match the part to your frame rather than trying to sell you a full-window replacement when a gasket swap would do.

Signs Your ES Windows Bathroom Remodeling Is Failing

• Fog between the panes. The seal has failed and moisture is now inside the insulated glass unit. In Los Angeles, the temperature swing between cool coastal mornings and hot inland afternoons accelerates seal fatigue, and a fogged ES Windows bathroom unit usually means the IGU needs replacement, not the whole frame.
• White haze or mineral streaks on the inside face of the glass. This is seal failure that has already cycled water in and out through dry CA summers. The glass isn’t dirty; the coating inside the IGU is etched and the unit is done.
• The window sticks, grinds, or drops when you open it. Aluminum track rollers and nylon glides wear flat over time, especially in bathrooms where steam and shampoo residue make the track gummy. If the sash tilts out of plane when you close it, a roller has collapsed.
• Water stains on the sill or drywall below the window. The weep holes at the bottom of the frame may be blocked, or the outer gasket has shrunk and cracked from years of direct sun. In a bathroom, that trapped water is also a mold trigger behind the sill.
• Condensation on the room side of the glass every morning. This can be normal for a bathroom after a hot shower, but if it persists all day and only on this window, the thermal break in a Series 850 may be compromised or you have a Series 700 doing what a non-thermal frame does in a humid room.

Replacement Cost & What’s Included

For Los Angeles homeowners, a bathroom remodel involving ES Windows parts breaks down like this:

• IGU (sealed glass unit) replacement for an ES Windows Series 700 or 850 bathroom window: $590 – $1,480 installed, depending on size and whether it’s tinted or tempered
• Full window insert swap (glass plus new gaskets, rollers, and latch): $1,180 – $2,950 installed
• Full bathroom remodel that includes ES Windows replacement work: $10,620 – $33,040, driven by tile scope, vanity, shower glass, and whether we’re moving plumbing

Every price is written before we pick up a tool. That’s the Kingswell Guarantee, which has been in force since 2004: a written price, a defined arrival window, a clean job site, and a written guarantee on every job. If the repair fails inside a year, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every ES Windows repair we do in Los Angeles.

DIY or Call Us?

You can safely check a few things yourself: whether the weep holes at the bottom of the frame are clear, whether the sash has visible gaps at the gasket line, and whether the window is square in its opening. Those observations help us quote the job over the phone.

What you shouldn’t do is remove an ES Windows sash, pry out an IGU, or attempt a track rebuild. These are aluminum-framed units under glazing tension, and a slipped screwdriver into tempered glass means a violent shatter and a trip to urgent care. We’ve also seen owners order the wrong IGU thickness online and end up with a window that doesn’t seat. Give me the whole picture first, then we pick up the tools. Call (936) 259-2607, tell us the frame depth and what you’re seeing, and we’ll bring the correct part and the right installer on the first trip.
