ECO Window Systems Bathroom Remodeling: The Sunnyvale Owner’s Guide

ECO Window Systems bathroom remodeling in Sunnyvale typically runs $9,000-$28,000 installed, depending on whether we’re refreshing a guest bath in Lakewood Village or gutting a master suite near Washington Park. We stock ECO Window Systems-compatible enclosures, hardware kits, and waterproofing assemblies, and we can usually measure and quote within 48 hours of your call. Most Sunnyvale owners first notice trouble when the frame seal starts weeping after winter rains, or when the sliding panel drags because the roller track has corroded in the hard water that runs through this part of Santa Clara County.

Which ECO Window Systems Models This Applies To

ECO Window Systems labels their bathroom enclosure lines with a stamped aluminum tag on the header rail, usually on the hinge side for swing doors or the fixed panel side for sliders. The tag shows a series prefix (ECO-BP for bypass sliders, ECO-PD for pivot doors, ECO-NS for neo-angle showers) followed by a four-digit year code and a width x height measurement in inches. We’ve worked on ECO-BP units from 2014 through 2022 in Sunnyvale homes, and the roller wheel diameter changed from 7/8-inch to 1-inch in 2019, which matters if you’re ordering replacement hardware online and cross-referencing part numbers. The OEM roller assembly is ECO part #RW-1900, but we also carry a sealed-bearing equivalent from a third-party manufacturer that outlasts the original in our experience, particularly in the mineral-heavy water supply that feeds the Lakewood Village area. If your frame is anodized bronze rather than brushed nickel, the wall jamb depth is 3/4-inch instead of 5/8-inch, a compatibility gotcha that trips up homeowners who measure width and height but skip the jamb profile.

Signs Your ECO Window Systems Bathroom Remodeling Is Failing

• Water pooling on the tile outside the enclosure. The vinyl sweep at the bottom of the door has hardened or torn, or the frame-to-wall silicone seal has separated. In Sunnyvale’s dry summers, caulk shrinks; in winter, the expansion-contraction cycle accelerates the gap.
• Door drags or jumps off the track. The roller wheels have flat-spotted from grit embedding in the bearings, or the aluminum track itself has corroded where hard water sits. We see this most in homes with whole-house softeners that were bypassed during filter changes.
• Glass panel wobble or rattle. The wall jamb screws have backed out of studs that weren’t hit during original installation, or the U-channel gasket has compressed after years of thermal cycling. The panel is still secure but the tolerance stack is gone.
• Visible mold or mildew on grout lines near the frame. Water is migrating behind the tile through a failed waterproofing membrane, the flexible sheet bonded to the studs before tile went up. This is the most expensive symptom because the enclosure has to come out to access the wall.
• Anodized finish chalking or pitting. The frame’s protective oxide layer has degraded from acidic cleaners or salt air if you’re west of El Camino Real. Once pitting starts, the frame is cosmetic-only; it won’t leak yet, but it’s no longer maintainable.

Replacement Cost & What’s Included

A full ECO Window Systems bathroom remodel in Sunnyvale runs $9,000-$28,000, with the spread driven by three factors: whether we’re working within the existing footprint or moving walls, the tile and fixture grade you select, and whether the waterproofing membrane behind the walls is intact. A frame-only replacement on a sound substrate starts around $4,500; a gut renovation with new plumbing rough-in, tile, and ECO enclosure lands in the $18,000-$24,000 range for a typical 5×8-foot hall bath. Our quote is a flat written price with material costs, labor hours, and subcontractor scope listed separately, so you see where each dollar goes before anyone picks up a tool. Under Clause 1 of the Haven Standard, that written price is delivered before any work starts, and no change proceeds without a signed change order. The 365-Day Done Right Promise covers the installation and waterproofing workmanship; manufacturer defects on the ECO frame or glass are handled through the OEM warranty we register at completion.

DIY or Call Us?

There’s safe checking, and there’s risky work. You can verify the model tag location, measure the opening width at three points (top, middle, bottom, since tub decks settle), and photograph any water stains on the drywall ceiling below, which tells us if the leak is active. What we don’t recommend: removing a frame that’s silicone-bonded to tile, because the tempered glass panels weigh 60-90 pounds each and the release torque can crack adjacent tile you’ll never match. The waterproofing membrane behind the wall is a single-layer system, meaning one slip with a putty knife and you’ve compromised the shower’s moisture barrier. If you’re seeing mold, water below, or any wobble in the glass, call (650) 405-3637. We’ll scope it, photograph what we find, and give you a written price before any work starts.
