ES Windows Construction in Los Altos, CA | Viceroy Construction
We handle independent ES Windows construction work across Los Altos, covering ZIP codes 94022, 94023, and 94024. What makes our work here different is straightforward: we know the original ES aluminum units on 1950s and 1960s ranch homes, and we know how Los Altos design review shapes what can go back in. If you’re planning a second-story addition or full rebuild and need an honest read on your existing ES Windows, call (877) 358-6557 for a free estimate.
Why Los Altos Residents Choose Us for ES Windows Service
We’ve pulled, re-glazed, and rebuilt ES Windows aluminum units across the Peninsula long enough to know the 1960s-era extrusions, glazing clips, and screen frames that fail on Los Altos ranch homes. Neil Drummond, our owner at Viceroy Construction, trained in the building trades program at West Valley College in Saratoga and has spent the better part of three decades doing this work as a General Contractor in Los Altos and across the South Bay. When we scope an ES Windows job, we’re looking at the framing behind the window, not just the glass. That’s the difference between fixing a symptom and fixing the opening.
We source replacement parts without manufacturer authorization or warranty claims. You get a straight answer on whether the right move is a repair or a full window replacement.
We serve the full Los Altos service area, from North Los Altos off Almond Avenue down to the Los Altos Hills fringe where grading and drainage inspections get tighter.

Common ES Windows Construction Problems We Solve in Los Altos
- Seized horizontal sliders and patio doors. Dry summer dust settles in the bottom tracks, then the first rains turn it to grit. Rollers flatten, tracks pit, and the unit won’t budge. We replace rollers and weatherstrip with aluminum-matched aftermarket parts when OEM is discontinued.
- Weeping single-pane glazing. Original ES aluminum single-pane units from the 1950s to 1970s lose their early 1/8-inch seals. Winter rain gets into the sill, sits there, and rots the rough framing behind pier-and-beam subfloor openings. By the time you see a stain, the wood’s usually wet.
- Chalked, oxidized frames and winter condensation. Mill-finish aluminum doesn’t hold up to Peninsula UV. The frames chalk, and thermal bridging makes the glass sweat hard in winter. We see paint and drywall staining at second-story heads regularly.
- Screen frames and glazing clips popping out. When a remodel disturbs an older ES install, frame racking cracks the clips and the screens fall out. This shows up a lot during additions where the existing windows stay in place while the structure moves around them.
- Rusted sill pans on second-story additions. We pulled a row of original ES single-hung windows off Almond Avenue that were weeping into new framing because the old sill pans had rusted through. The frames looked fine from inside. The flashing was gone.
ES Windows Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos is a low-density, single-story ranch-home town where most construction work is a second-story addition, whole-house remodel, or tear-down rebuild on a mature-lot property. That creates a specific problem for ES Windows work that you won’t run into the same way in Sunnyvale or ES Windows repair in Mountain View: the design-review process and the neighbors who show up to it. Because lots are wide but shallow and many streets were built out by the 1960s, a second-story addition often triggers a neighborhood compatibility review and privacy concerns from adjacent one-story ranches. Rear-facing window profiles and sightlines have to stay low-profile. We’ve had ES horizontal sliders and picture-window placements get scrutinized precisely because they faced an abutting ranch lot. The window you want isn’t always the window review will pass, and we plan for that from the first takeoff.
ES Windows Models & Products We Service in Los Altos
We work on the full range of ES Windows product lines, including the ES-1000 and ES-2000 Series aluminum single-hung windows, ES Series horizontal sliding windows, ES Series fixed picture windows, and ES Series sliding patio doors. For repair work, we match original ES extrusion profiles and glazing with OEM parts where they’re still available. Where OEM is discontinued, we use quality aluminum-matched aftermarket rollers, weatherstrip, and glazing gaskets that fit the profile correctly. We stock common roller sets and weatherstrip profiles for fast Los Altos turnaround, so a seized slider doesn’t sit for two weeks waiting on a part.
Looking for new ES Windows rather than repair? That falls under our broader ES Windows sales & service scope, and we’ll walk you through the thermally broken options that stop the winter condensation problem for good.

FAQs – ES Windows Construction in Los Altos
Replace them now if they’re in any wall that’s getting opened up. Doing it during the addition means the rough openings, flashing, and water management go in correctly while the wall is exposed. You avoid paying twice for stucco repair and trim. On original 1950s to 1970s single-pane ES units, we’ll repair rollers and seals when the frame is sound, but if the units are leaking or the frames are chalked out, now is the cheaper time to swap them. Call (877) 358-6557 and we’ll scope it before you open the wall.
Yes, and it’s a bigger problem here than people expect. Weeks of dry weather deposit fine dust in the bottom tracks. When the rains start around November, that dust turns to a grinding paste. Rollers flatten, tracks pit, and the slider seizes. We replace the rollers and clean or replace the track as needed. If it’s a recurring problem, we’ll tell you honestly whether the unit is worth saving or whether replacement makes more sense.
Sometimes. We match original ES extrusion profiles and glazing with OEM parts where they’re still in production. Where a profile is discontinued, we use aluminum-matched aftermarket components sized to the opening. If the profile can’t be matched cleanly, we’ll say so and show you a replacement unit that fits the rough opening and the design-review constraints. We don’t force a repair that’ll look wrong in six months.
Heritage street trees and mature-lot setbacks limit how far you can push an addition’s footprint. Shallow lots mean the second story sits closer to the property line, which drags in privacy and sightline concerns from adjacent one-story ranches. Low-profile rear windows and careful placement matter more in Los Altos than in most neighboring cities. Our ES Windows service in Seven Trees doesn’t face the same design-review pressure, which tells you how specific this is to Los Altos.
Most likely the original single-pane glazing seals have failed and water is getting past the sill into the rough framing. On pier-and-beam homes, the subfloor opening below the window gives water a path, and the wood stays wet longer than it would on a slab. If the sill pan is rusted through or the flashing was never correct, the stain is just the visible part of a framing problem. Call (877) 358-6557 for an exact diagnosis and line-itemed estimate.
