ES Windows Bathroom Remodeling: The Los Angeles Owner’s Guide
If you own a home with ES Windows products and the bathroom around them is failing, we can replace the window, repair the surrounding structure, and remodel the full space without subbing the job out. Most ES Windows bathroom remodels in Los Angeles run between $10,620 and $33,040, depending on the scope, window count, and whether we’re fixing water damage or just replacing tired tile. Trevor Nash has opened plenty of bathroom walls behind ES Windows units and found exactly what you’d expect after ten or fifteen years of steam exposure: rotted sills, swollen framing, and caulk that gave up years ago.
What most owners notice first is a window that won’t open cleanly, or moisture collecting on the sill after every shower. Another common tell is peeling paint or soft drywall below the window. That’s the failure pattern we step into most often in Los Angeles, in houses from Silver Lake to Westchester to Woodland Hills.
Which ES Windows Models This Applies To
Penhallow Remodeling Los Angeles works on bathroom remodels where ES Windows products are in place or will be installed as part of the job. The compatibility question matters because ES Windows makes multiple lines, and the frame dimensions on a Series 810 slider are not interchangeable with a Series 830 casement. We match by measuring the rough opening, the frame depth, and the glass type printed on the corner tag of the sash. If the label is gone, we still have ways to identify the unit, but a torn-off tag usually means a special-order replacement rather than a stock pull.
Here’s the gotcha most Los Angeles homeowners don’t expect: an ES Windows unit that was installed as part of an original build fifteen years ago may not be made in that exact size anymore. When that happens, we resize the rough opening carefully so the waterproofing detail stays correct. In a bathroom, that detail is the whole ballgame. The window is only as good as the sill pan and flashing behind it.
On OEM versus aftermarket: we use genuine ES Windows components when we can get them, and we tell you the price difference up front if a quality aftermarket equivalent is a better fit for the budget. We also handle KraftMaid, Cambria, and Silestone material needs on remodels that touch more than just the window.
Styles & brands we work with
Signs Your ES Windows Bathroom Remodeling Is Failing
- Condensation between the panes. The sealed unit has lost its gas fill or the edge seal has cracked. No amount of wiping fixes it; the glass needs to be replaced.
- The window binds or sticks when you open it. Humidity swells the frame or the hardware has corroded. Forcing it usually breaks the crank mechanism or the sash lock.
- Soft drywall or bubbling paint under the window. Water has been getting behind the exterior trim or leaking at the sill. This is the one we treat as urgent, because the framing is already wet.
- You can feel air moving around the closed sash on a breezy day. The weatherstripping is shot or the frame has shifted. In a bathroom, those are the same thing after a few wet seasons.
- Black staining at the bottom corners of the frame. That’s mold, and it means the water path has been wrong for a while. We open the wall enough to see the full picture before quoting a fix.

AfterReplacement Cost & What’s Included
In Los Angeles, an ES Windows bathroom remodeling project typically falls between $10,620 and $33,040 installed. A window-only swap with a standard-sized unit and no structural surprises lands toward the low end. The number climbs when we’re replacing rotted framing, moving plumbing, waterproofing the whole shower surround, and pulling permits for the structural work.
Every estimate from Penhallow Remodeling Los Angeles includes a written line-item price before we start. Not a range, not a verbal ballpark. The window cost, the trim cost, the waterproofing labor, the demo, the haul-away, and the finish work, all laid out. If the job changes, we talk about the change order before the change happens, never at the final invoice. Every remodel also carries our 365-Day Done Right Promise in writing: if the work fails inside a year, we come back and make it right at no charge.
DIY or Call Us?
You can safely check a few things yourself. Is the window caulk cracked? Are the weep holes on the exterior bottom track clear? Does the frame feel loose when you press on it? Those are useful things to know before you call, and they help us quote faster. What we don’t recommend is pulling the window or opening the wall on a bathroom exterior. That work involves the weather barrier, possible asbestos-era insulation, and a waterproofing sequence that has to be right the first time.
One more honest note: replacing a bathroom window without fixing the underlying moisture problem means you’ll replace it again in five years. That’s the conversation we’d rather have before the demo, not after. Call (213) 277-6578 and we’ll walk the job with you. Give you a number first, then pick up the tools.
FAQs
In a properly waterproofed bathroom, expect fifteen to twenty years from the frame and hardware, but the sealed glass unit can fog out in as little as eight years in a steamy bathroom with weak ventilation. Coastal moisture near areas like Playa del Rey or San Pedro shortens that timeline. Call (213) 277-6578 and we’ll tell you if the window is worth saving or if the whole surround needs redoing.
Sometimes, when the failure is isolated to a single component like a crank handle or a sash lock, we can replace that part and tighten the frame without a full swap. If the glass is fogged or the frame is water-damaged, repair becomes a temporary patch. We’ll show you both paths and the written price for each before you decide.
A window-only replacement inside an existing opening usually takes one day. A full bathroom remodel with window reframing, waterproofing, tile, and fixtures typically runs two to four weeks in Los Angeles, depending on permit turnaround and material lead times. We give you the schedule before we start and a defined arrival window for each day of work.
We keep common hardware and seal components on hand and source ES Windows-specific sash and frame components as needed through the local supply network, so you’re not waiting on a general contractor without trade connections. For full remodel work involving KraftMaid, Cambria, or Silestone products, we coordinate the material orders with the same written-price approach. Call (213) 277-6578 for a free estimate on your specific setup.
