ES Windows Bathroom Remodeling: The Pasadena Owner’s Guide
ES Windows bathroom remodeling in Pasadena typically runs $9,000 to $28,000 installed, depending on whether we’re replacing a tub surround, converting to a walk-in shower, or doing a full gut-out. Most jobs wrap in 7 to 14 working days, and we carry the common ES Windows trim, seal, and glass hardware on our trucks so we don’t stall mid-project waiting on parts. Here’s what usually brings Pasadena homeowners to us: the window frame above the tub has started to rot at the sill, water’s getting behind the tile where the window meets the shower surround, or the original 1990s-era window simply won’t seal anymore and every shower fogs the glass and drips condensation onto the sill.
We’re an independent remodeling contractor in Pasadena, not affiliated with ES Windows. But we’ve pulled enough of their units out of old Arcadia and Hastings Ranch bathrooms to know exactly how they fit, fail, and what it takes to make a bathroom look like the window was always meant to be there.
Which ES Windows Models This Applies To
Most ES Windows bathroom fixtures we encounter in Pasadena fall into three buckets: the original aluminum sliders common in 1960s to 1980s Ranches, vinyl casements and awnings from the 1990s and early 2000s, and a smaller run of wood-clad units you’ll find in Craftsman-era homes around Bungalow Heaven and Madison Heights. Each one has a different rough opening and mounting flange, so the first thing we do is measure the actual frame, not the visible glass.
The compatibility gotcha: ES Windows used a proprietary flange depth on many of their aluminum units. A standard replacement window drops into the same opening but sits 3/8″ proud of the wall, which throws off your tile layout and your Schluter edge trim (the metal strip that waterproofs where tile meets the window opening). That’s why we rarely recommend an off-the-shelf box-store swap. For most Pasadena bathrooms we spec an ES Windows-compatible vinyl replacement with a custom jamb extension, or we rebuild the opening and flash it properly before tile goes back up. OEM trim and glass seals for the original units are still available through a few supply houses in the San Gabriel Valley, but aftermarket compression seals typically last longer in a wet bathroom environment and cost 30 to 40 percent less.
Styles & brands we work with
Signs Your ES Windows Bathroom Remodeling Is Failing
- Condensation where the window meets the tile. The thermal seal between the panes is gone, or the window’s weep holes are clogged and water’s pooling inside the frame. Either way, moisture is now living inside your wall cavity.
- Black staining or soft drywall at the sill corners. This is rot, not mildew. In Pasadena’s winter rains followed by hot dry summers, a failed sill pan lets water into the framing, where it sits and eats the wood. By the time you see the stain, the framing usually needs sistering.
- The window won’t close flush against the frame. Aluminum frames twist slightly over decades of thermal cycling, especially on south-facing Pasadena walls that bake in August. A 1/8″ gap let’s shower steam escape into the wall every single day.
- White powder or corrosion on the aluminum edges. That’s the finish breaking down from constant moisture exposure. In a bathroom especially, it means the frame is wicking water behind the tile flange.
- You can feel air moving through the window with the shower running. The gasket is shot, the frame is racked, or both. The window is no longer doing its one job: keeping the outside out and the inside dry.

AfterReplacement Cost & What’s Included
For a Pasadena bathroom where the ES Windows unit needs replacement as part of a remodel, you’re looking at $9,000 to $28,000 installed, with the window portion of that job typically landing between $1,800 and $3,200 of the total. The spread comes down to three things: whether the framing around the window is salvageable, what tile and waterproofing method you choose, and whether we’re doing a straight window swap or moving or enlarging the opening.
Every quote you get from Sawyer Remodel Pasadena is a written line-item price before work starts. That includes the window or part itself, framing repair, waterproofing, tile prep, labor, and a 365-Day Done Right Promise: if it’s not done right, we make it right. If a repair fails within that year, the second visit is free, no argument. We don’t do change orders once the number is approved.
DIY or Call Us?
Here’s the honest split. You can absolutely pop the interior trim off and look for rot. You can run the shower, wait for condensation, and track where the water pools. You can even measure the visible glass and frame width if you want to price a replacement yourself. What you should not do is pull the window out and try to re-flash a shower-side opening without knowing how to tie the waterproofing membrane into the new flange. One missed seam behind that window means water running down the inside of your wall for years before the tile ever shows it. Luca Romano has rebuilt enough of these in Pasadena to tell you the same thing he tells his crew: the work tells you everything, you just have to know how to listen to it.
If you want a second set of eyes on your ES Windows bathroom before you commit to a full remodel, call (626) 657-5396. We’ll come look, tell you if the window’s worth saving, and give you a written price either way.
FAQs
In a Pasadena bathroom you can expect 20 to 30 years from the original unit before the thermal seal fails, with aluminum frames on south-facing walls failing sooner due to direct sun and the constant wet-dry cycle of daily showers. If you’re past year 20 and seeing condensation or corrosion, plan for replacement during your next remodel rather than after water damage forces it. Call (626) 657-5396 for an exact assessment and a free written estimate.
Sometimes, if the frame is still square and the rot hasn’t reached the rough opening we can replace the glazing, seals, and hardware in place. But in a shower-exposed opening, a patched frame still has original female joints and weep holes working against you. Most Pasadena homeowners get better long-term value from a full replacement with a properly flashed rough opening. Call (626) 657-5396 and we’ll tell you which side of that line your window falls on.
Once we’ve got the old unit out and inspected the framing, the window replacement itself is a one-day job. The full bathroom remodel with tile, waterproofing, and finishing typically runs 7 to 14 working days. You’ll get photo updates before and after the window work so you can see the flashings, the framing, and the tile prep without standing in the dust.
We stock common ES Windows-compatible compression seals, glazing beads, and shower-safe hardware on our trucks, and we can source OEM trim pieces through San Gabriel Valley supply houses within a few days. For most remodels we pair the window replacement with a full waterproofing rebuild so you’re not paying labor to fix the same leak twice. Call (626) 657-5396 for a written quote, always free.
