ES Windows Bathroom Remodeling: The Los Angeles Owner’s Guide
If you have an ES Windows product in your bathroom and the surrounding space needs to be rebuilt around it, a full ES Windows bathroom remodel in Los Angeles typically runs $10,620 to $33,040 installed. Most jobs that involve working around existing ES Windows frames and preserving their water seal get done in three to six weeks depending on scope, and yes, we can start with a window evaluation on our first visit. The way owners usually find us is simple: a window seal has failed, water has gotten into the drywall or sill, and the tile around it is now buckling or stained. What began as a window problem has become a bathroom problem.
We’re Mason Remodeling, and while we’re an independent contractor and not affiliated with ES Windows, we work around their products constantly across Los Angeles. If the window itself needs service, we’ll tell you plainly and point you to the right channel. If the bathroom around that window needs to be rebuilt correctly so it never leaks again, that’s the work we do every week.
Which ES Windows Models This Applies To
ES Windows makes a wide range of vinyl and aluminum window products, and the bathroom-relevant models we most often work around in Los Angeles homes are the ES-6000 and ES-7000 series sliding windows, the ES-4300 casement series, and the ES-240 single-hung line. Each has a different frame depth and flange profile, which matters a lot when you’re setting tile, waterproofing a shower wall, or replacing a rotted sill. The compatibility gotcha most homeowners miss: the ES-4300 casement has a narrower interior frame reveal than the sliders, so tile trim pieces that work fine on an ES-6000 will not fit cleanly on a 4300 without a custom cut. We check the manufacturer label on the inside of the frame before we order anything.
For most bathroom remodels, you do not need a new ES Windows unit. What you need is a contractor who understands the existing frame’s moisture barrier and can tie new waterproofing into it without voiding the window’s own warranty. We treat the ES Windows frame as the fixed point of the room and build everything else to meet it, not around it. When a full window replacement is genuinely called for (rot in the frame, failed glass seal, damaged balance), we source the OEM part or a spec-matched aftermarket equivalent and tell you the price difference before you decide.
Styles & brands we work with
Signs Your ES Windows Bathroom Remodeling Is Failing
- Peeling paint or darkened drywall below the window. This is almost always water wicking down from a failed sill pan or a broken seal at the window’s lower flange. In Los Angeles, the wet-dry cycling from shower steam accelerates this faster than homeowners expect.
- Caulk that keeps splitting along the window perimeter. When the rough opening shifts (and older LA homes on expansive clay shift a lot), rigid caulk fails before the window does. The cause is movement, and the fix is a proper flexible seal, not another bead of hardware-store caulk.
- Tile grout cracking in a stair-step pattern away from the window corner. This is a structural tell. The window opening is moving and taking the tile assembly with it. A remodel that doesn’t address the underlying framing will crack again within a year.
- Condensation between panes or visible fog inside the glass. The ES Windows glass seal itself has failed. No amount of bathroom ventilation fixes this. You’re looking at a new sash or an insert replacement, and we can handle that as part of the remodel.
- A musty smell that lingers after cleaning. Moisture is trapped in the wall cavity behind the window surround. By the time you smell it, the damage is underway. The remodel has to include mold remediation and new waterproofing, not just cosmetic tile work.
Replacement Cost & What’s Included
In Los Angeles, a bathroom remodel that works around or replaces an ES Windows unit runs $10,620 to $33,040, with most mid-size jobs landing between $14,000 and $22,000. The spread depends on whether you’re keeping the existing window and rebuilding the surround, replacing the sash only, or pulling the entire frame and re-flashing the rough opening, plus the square footage of tile, the level of waterproofing required, and whether you’re moving any plumbing.
Here’s what the numbers look like:
- Rebuild tile surround around existing ES Windows unit: $10,620 – $18,880
- Full bathroom remodel including window sash replacement: $14,160 – $25,960
- Full bathroom remodel including complete window frame replacement: $17,700 – $33,040
- Window-only repair or sash replacement (no tile work): $2,360 – $5,310
Every Mason Remodeling job in Los Angeles comes with a written price before we start, so you know the window-related line items and the tile-related line items separately. No verbal estimate that grows on the final invoice. The work is covered by our 365-Day Done Right Promise: if it is not right within a year of completion, we make it right at no cost to you.

AfterDIY or Call Us?
There are two things you can safely do before calling anyone. First, read the ES Windows label on the inside of the frame and write down the model number and the manufacturing date code. Second, check the caulk lines and photograph what you see so we know what we’re walking into. That’s where DIY should end. Cutting out a failed window, re-flashing a rough opening, and tying waterproofing into a shower wall is skilled work, and getting the flashing sequence wrong is how a $500 window repair becomes a $15,000 mold and rot rebuild. Window removal also involves tempered or laminated glass units under tension from the frame, and a mishandled pane can cause serious injury.
I’ve spent much of two decades remodeling Los Angeles bathrooms and have pulled apart enough bad window surrounds to know exactly what the previous guy did wrong. The fix isn’t a YouTube video. It’s a crew that does this weekly and puts the price in writing before they touch your wall. Call (803) 680-2547 for a free estimate.
FAQs
A correctly rebuilt ES Windows bathroom surround in Los Angeles should last 20 to 30 years before the next remodel. The window’s own vinyl or aluminum frame will often outlast the tile around it. The lifespan killers are bad waterproofing and silicone caulk masquerading as a structural seal, which is why we insist on flexible sealants and proper flashing at the window-to-tile junction. Call (803) 680-2547 and we’ll walk through what your specific window needs.
No. Once the hermetic seal on an ES Windows insulated glass unit fails and moisture gets between the panes, the glass unit has to be replaced. You cannot reseal a breached IGU reliably. The good news is we can replace just the sash or the glass pack in many ES Windows models without pulling the entire frame. Call (803) 680-2547 for an exact quote on your model.
A sash or glass-pack replacement takes one day on site. A full frame replacement with re-flashing takes one to two days depending on stucco or siding condition. A complete bathroom remodel that includes the window work typically runs three to six weeks. We’ll give you a written schedule before work starts. Call (803) 680-2547 to talk dates.
We stock the most common ES Windows replacement balances, locks, and weatherstripping on our service vehicles and carry spec-matched aftermarket equivalents for the parts ES Windows no longer manufactures. For anything unusual, we source OEM through our supplier network and have it in hand before your scheduled date. We also work with KraftMaid, Cambria, and Silestone for the bathroom’s cabinetry and countertop components. Call (803) 680-2547 with your model number and we’ll check availability while you’re on the phone.
