ECO Window Systems Construction in Los Altos, CA | Viceroy Construction
We provide independent ECO Window Systems installation and repair across Los Altos, from single-window retrofits to full-scale second-story additions. What sets our ECO Window Systems work here apart is that we understand how this brand’s frames and glazing hold up against Los Altos’s unique combination of 1950s ranch homes, wide-but-shallow lots, and a design-review process that shapes every window decision on the second story. Viceroy Construction is not authorized by or affiliated with ECO Window Systems – we diagnose your windows on their own merits. Call (877) 358-6557 for a free estimate.
Why Los Altos Residents Choose Us for ECO Window Systems Service
Most window contractors in Los Altos treat every brand the same. We don’t. We’ve spent years installing, retrofitting, and performing ECO Window Systems in Loyola and across the Peninsula, so we know how this brand’s vinyl frames, glazing seals, and hardware behave through Los Altos’s long dry summers and wet November – March storms. Neil Drummond, our owner, grew up in the Saratoga foothills and trained in the building trades program at West Valley College – he still applies those structural and framing fundamentals when scoping window replacements and additions. For Los Altos homeowners, that means we catch the problem behind the window: the settling opening, the missing drainage plane, the rough sill that was never flashed. The details you don’t see are the ones that matter most.

Common ECO Window Systems Construction Problems We Solve in Los Altos
- Failed glazing seals on older vinyl units. We see fog and condensation trapped between panes on ECO vinyl single-hung and double-hung windows in Los Altos’s original 1950s – 70s ranch homes. Long dry summers bake the seals, then the Peninsula’s wet winters force moisture into the gap. On a sound frame, we replace the glazing unit. On a 30-year-old single-pane unit, we tell you honestly when replacement makes more sense.
- Sticking and racking aluminum-frame ECO sliders. Original ranch-era rough openings settle over time on pier-and-beam and slab foundations, especially on the Los Altos Hills fringe where drainage and grading shift more noticeably. The sliders lose their rollers, the frames rack, and the window binds. We source OEM ECO rollers and balances where available, or matched-quality aftermarket hardware when OEM is discontinued.
- Water intrusion at sill and head flashings. Many ECO units in Los Altos were installed into stucco ranch walls without proper drainage planes. We see the evidence after the first real storm – interior drywall staining below the window. The fix isn’t caulk; it’s rebuilding the flashing detail so water has a path out.
- Warped or cracked vinyl sashes and worn weatherstripping. These show up as drafts and interior condensation on cold mornings. They also get flagged during second-story addition inspections when the original first-floor windows are still in place – something Los Altos’s design-review process often forces homeowners to address before sign-off.
- Mismatched replacements on additions. Homeowners add a second story with new ECO casement or awning units, then discover the original first-floor windows don’t match in style, glazing, or sightline. We plan the entire facade at once so the addition doesn’t look pasted on.
ECO Window Systems Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos streets were built out by the 1960s, and the lots are wide but shallow. That means when a homeowner wants a second-story addition, they’re almost certainly triggering a neighborhood compatibility review – and adjacent one-story ranches have a say. Privacy objections are common. So window placement, glazing choice, and sightline planning aren’t just design preferences here; they’re the difference between a permit that clears review and one that stalls. On a second-story addition off a ranch home near the Los Altos Hills fringe, we replaced original single-pane aluminum sliders with ECO casement units in the new upper story, then matched the existing first-floor openings with ECO sliders so the facade stayed consistent — similar to our ECO Window Systems repair in Mountain View projects. We rebuilt the sill flashings on the original stucco walls, where past installs had skipped a drainage plane. The homeowner noted the fogging and draft complaints stopped the first wet week of that winter. That’s the kind of thing you only learn by doing the work in Los Altos, not just reading a spec sheet.
ECO Window Systems Models & Products We Service in Los Altos
We install and repair ECO Series vinyl single-hung and double-hung replacement units, ECO Aluminum Series slider windows (very common in 1950s – 70s ranch retrofits across Los Altos), ECO casement and awning units for additions and second-story bump-outs, and ECO fixed/picture window units with tempered glazing for large-view openings. On the parts side, we source OEM ECO Window Systems sashes, rollers, balances, and glazing units where they’re available. When OEM parts are discontinued or cost-prohibitive, we choose matched-quality aftermarket hardware and tell you exactly what we’re using and why. We’re an independent contractor, so our only interest is the window working correctly – not selling you a manufacturer’s replacement script.

FAQs – ECO Window Systems Construction in Los Altos
No. We’re an independent contractor, not an authorized ECO Window Systems dealer or installer, so any manufacturer warranty would come from the component manufacturer for the parts themselves – not from our labor. That said, we use OEM parts where available and stand behind our workmanship. If a seal fails or a sash warps after we’ve installed it, call us – we’ll come back. Call (877) 358-6557 to discuss your specific windows.
Both, depending on availability and cost. We source OEM ECO sashes, rollers, balances, and glazing units whenever they’re still made. For discontinued model lines, we use matched-quality aftermarket hardware that meets or exceeds the original spec – and we tell you which one you’re getting before the work starts.
A standard window replacement – one to five units – usually takes one to two days of on-site work. A full-perimeter replacement at a Los Altos ranch home might stretch to four or five days, depending on the flashing conditions we find behind the stucco, while ECO Window Systems repair in Stanford follows a similar timeline. Second-story additions are a multi-week scope, and the neighborhood compatibility review can extend the permitting timeline before we ever set foot on site.
We service ECO Series vinyl single-hung and double-hung replacement units, ECO Aluminum Series sliders, ECO casement and awning units, and ECO fixed/picture window units. If you have an older unit and you’re not sure of the model, take a photo of the corner label or the frame profile and we’ll identify it during the estimate.
Most Los Altos homeowners spend between $4,500 and $15,000 on window replacement, with the high end covering impact-rated units or a full-perimeter scope tied to an addition. The exact number depends on how many windows, the glazing spec, and how much flashing repair we uncover once we open the wall. Estimates are free – call (877) 358-6557 and we’ll give you a written number.
