ECO Window Systems Bathroom Remodeling: The Los Angeles Owner’s Guide
If you own an ECO Window Systems window in a bathroom that’s being remodeled, or you’ve discovered your ECO window is leaking, fogging, or sitting in a rotted frame as part of a larger bathroom rebuild, we can match it, source it, and install it. A bathroom remodel involving ECO Window Systems window work in Los Angeles typically runs $10,620 – $33,040 depending on scope, and we’re usually on-site within a few days of your call, not weeks. Most Los Angeles homeowners find the problem the hard way: peeling paint at the sill, a window that won’t lock anymore, or moisture collecting between the panes long after the bathroom fan has done its job.
We’re an independent Los Angeles remodeling contractor, not an ECO Window Systems dealer or affiliate. That means we don’t push one brand. We spec the right window for the opening, the moisture load, and the way your bathroom actually gets used, then price it in writing before any work starts.
A quick note from Isaac Pruett, our owner: “Know who’s coming, know what it costs, know it’s backed up – everything else is just noise.”
Which ECO Window Systems Models This Applies To

ECO Window Systems produces vinyl and aluminum window lines found throughout Los Angeles homes built or renovated from the early 2000s onward. Bathroom-specific applications are usually one of three configurations: a fixed picture window, a single-hung with a top sash that tilts in, or a horizontal slider. The most common ECO series we see in Los Angeles bathrooms are the ECO 2000 and ECO 3000 vinyl lines, along with older aluminum-frame ECO windows that predate the vinyl push.
Here’s the compatibility gotcha most Los Angeles owners hit: ECO Window Systems changed its frame depth spec around 2012. Windows manufactured before that year have a slightly narrower frame profile, which matters when you’re trying to retrofit a new window into an existing tile surround. Measure the frame depth from the interior drywall to the exterior stucco edge. If it’s under 3.25 inches, you’re likely dealing with a pre-2012 unit, and we’ll need to check the rough opening before ordering any replacement sash or full window. The model label is on the inside edge of the frame, visible when you open the sash. It lists the series, the glass type, and the manufacture date.
For ECO Window Systems specifically, we recommend OEM glass packs when the window is under 10 years old and the frame is still square and true. For older units, a quality aftermarket sash matched to the rough opening usually makes more financial sense than chasing an obsolete OEM part number. We stock common Los Angeles bathroom window sizes on the truck: 24×36, 28×36, 32×36, and custom-order anything outside that.

Signs Your ECO Window Systems Bathroom Remodeling Is Failing
- Condensation between the glass panes. The seal on the insulated glass unit has failed. In Los Angeles humidity, that fog never dries out on its own, and it means the gas fill between the panes is gone and the window’s thermal performance has dropped.
- The sash won’t stay open or closed. The spiral balancers or block-and-tackle springs inside the frame have worn out. This is a common ECO Window Systems failure after 8 – 12 years of daily use in a steamy bathroom.
- Water stains or soft drywall under the window. This usually isn’t the glass. It’s the flashing or caulking at the sill, and in Los Angeles homes with stucco exteriors, the drainage plane behind that stucco could be holding water against the rough opening.
- Mold or mildew on the frame itself, not the glass. Bathroom humidity is condensing on a cold aluminum or vinyl frame. That signals an airflow problem in the room, not just a window problem, and it’s something we address during the remodel.
- The window is painted or caulked shut. Previous owners in Los Angeles sometimes caulk a failing thermal seal shut rather than fix it. If you have to pry the window open, that’s a red flag that the unit needs replacement, not another bead of caulk.

AfterReplacement Cost & What’s Included

Here’s how pricing breaks down for ECO Window Systems bathroom work in Los Angeles:
- Window replacement only (same rough opening): $5,310 – $17,700 per window, including the window, flashing, caulking, and interior trim.
- Full bathroom remodel including window replacement: $10,620 – $33,040, which covers demolition, framing corrections, window install, waterproofing, tile, fixtures, and finish work.
- Small bathroom remodel (window + vanity + flooring): $5,900 – $14,160 on the compact end.
- Tub-to-shower conversion with window work: $4,130 – $11,800 depending on whether we’re relocating or resizing the window opening.
The biggest cost driver is whether the rough opening needs reframing or resizing. Los Angeles bathrooms built in the 1970s and 1980s often have window openings that don’t match any modern ECO Window Systems size, which means a frame-and-sheath job before the new window goes in. Labor includes tear-out, any structural repair, waterproofing, installation, trim, and haul-away. Every quote is line-item, in writing, before we start. No change orders unless you ask us to add work.
DIY or Call Us?
You can safely do two things yourself: look for the model label on the inside edge of the frame, and take three measurements (width, height, and frame depth) so you can describe the window accurately over the phone. You should not attempt to remove an ECO Window Systems window from a tiled bathroom wall yourself. Cutting out a flanged window without damaging the waterproofing beneath it is a fast route to a rotted rough opening, and in Los Angeles, a leak behind the stucco can go unnoticed for years. The glass units are also heavy, and a dropped sash on tile causes real damage. If you’re handy, you can remove the interior trim and assess what’s behind the drywall. That’s genuinely useful. But the removal, flashing, and reinstallation is a job for someone who’s done a few hundred of them. Call (803) 680-2547 and we’ll walk you through what you’re looking at.
FAQs

Plan on 15 – 20 years for the frame and 10 – 15 years for the insulated glass seal, though Los Angeles sun exposure shortens that on south- and west-facing bathroom walls. If your window is over 12 years old and showing seal failure, replacement is usually cheaper than repeated sash swaps. Call (803) 680-2547 for a free assessment.
A failed glass seal can sometimes be addressed with a new sash or glass pack if the frame is still square and the ECO Window Systems model is still in production. But rotted frames, failed flashing, or non-standard openings usually need a full replacement. We’ll tell you which one you need, and why, before you spend anything.
A straight same-size window replacement takes 2 – 3 hours once we’re on site. If we’re reframing the opening or working it into a larger remodel, the window install itself is a half-day task within the larger project schedule. Call (803) 680-2547 for an honest timeline based on your exact job.
We stock common bathroom window sizes and the hardware that fails most often: spiral balancers, tilt latches, sash locks, and replacement glazing bead. For ECO Window Systems-specific OEM parts, we order direct from our supplier network and typically have them in hand within 3 – 5 business days in Los Angeles. We also work with KraftMaid, Cambria, and Silestone products when your bathroom remodel spans beyond the window itself.
If you’ve got an ECO Window Systems window in a bathroom that needs work, call (803) 680-2547. We’ll send a verified technician with a name and photo before arrival, put the price in writing before any work begins, and stand behind the job for 365 days from completion. Every project gets a written guarantee. No surprises.
