ES Windows Construction in Sunnyvale, CA | San Bruno Construction

We provide independent ES Windows service across Sunnyvale, from single-panel slider repairs to full Title 24-compliant replacements. What makes our work here different is simple: we know how these aluminum and vinyl units fail inside 1950s-60s Eichler and ranch tract walls, and we know what Sunnyvale’s Planning Department will flag during design review before we ever cut an opening.

And we coordinate every trade, permit, and inspection under one contract.

Why Sunnyvale Residents Choose Us for ES Windows Service

We’ve pulled apart enough failed ES Windows units in Sunnyvale and nearby ES Windows in Mountain View to know exactly what goes wrong and when. The Series 2000 and 2100 aluminum sliders that went into so many 1960s ranch homes have predictable failure points: felt seals that disintegrate after decades of wet winters, glazing beads that crack under thermal cycling, and sill pans that rust out behind stucco where shallow roof overhangs never kept rain off the window line. When you call us, you’re not getting a tech who sees one ES window a month. You’re getting a crew that has reset leaking openings in the 94086 and 94087 tracts enough times to know what’s behind the stucco before we open it up.

Noel Carvalho, our owner, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and think through load paths before a single tool comes out of the truck. That discipline carries into every ES Windows job we run in Sunnyvale. We source OEM rollers, latches, and glazing beads where the series is still supported, and we keep dimensionally matched aftermarket options on hand for discontinued lines so your job doesn’t stall waiting on a part. For full ES Windows sales & service across the Peninsula and South Bay, we’re the crew homeowners call when they want the job done once.

Common ES Windows Construction Problems We Solve in Sunnyvale

• Failed glazing seals on aluminum sliders. The desiccant inside the sealed unit saturates after enough Sunnyvale wet-winter cycles, and once the panel fogs permanently between panes, no amount of surface cleaning fixes it. We re-glaze or replace the sash, and we check the frame for the water damage that usually comes with it.
• Shot felt-and-fin-seal weatherstripping. Older ES Windows aluminum sliders relied on felt and fin seals that degrade into grit. Once the track fills with debris, the panel racks and leaks at the sill during winter rain intrusion. Sunnyvale’s dry summers bake whatever’s left of the seal, so the problem compounds fast.
• Sill pan and flashing failures in stucco walls. Original ES units were often set directly into 1950s stucco walls with shallow roof overhangs, which means water tracks behind the nail fin and rots the rough opening. By the time you see water staining inside, the sill pan is usually gone.
• Warped vinyl sashes on south- and west-facing elevations. Years of Sunnyvale UV exposure and thermal cycling warp vinyl slider sashes until the latch and roller hardware pulls loose. We replace the sash with a Title 24-compliant unit and address the seal so it doesn’t happen again in five years.
• Aluminum sliding glass door systems that bind or leak. The same felt-seal and track-grit problem hits ES Windows patio sliders hard in Sunnyvale. Panels rack, rollers wear unevenly, and winter rain finds the seam at the sill. We replace rollers, reset the track, and re-flash the pan when the rough opening allows.

ES Windows Service in Sunnyvale: What Local Conditions Mean for Your Equipment

Here’s what most General Contractor – Sunnyvale competitors don’t account for: Sunnyvale’s Planning Department enforces Neighborhood Preservation design review plus Title 24 energy compliance on remodels and additions. That means any ES Windows replacement in the 94086 and 94087 Eichler and ranch tracts has to be documented for U-factor and SHGC, not just matched to the old opening. We’ve processed enough of these reviews to know what the city will accept and what sends the submittal back. On an Eichler-era ranch off Fair Oaks in the 94086 ZIP, our crew opened up a leaking ES Windows aluminum slider and found the original felt seals gone and the sill pan rusted through behind the stucco. We reset the opening with a new flashed sill pan, re-glazed the fixed panel, and installed a Title 24-compliant vinyl slider with documentation the city’s design review accepted. The winter leak stopped and the rough-in passed inspection the first time. That’s the difference between a window swap and a window job done for Sunnyvale’s actual rules.

And for those of us who work here, including crews handling ES Windows in Santa Clara, Sunnyvale construction is defined by the collision of two eras: demolition/rebuild of 1950s-60s Eichler and ranch tract homes now worth $2M+ as teardowns, and high-density infill around Downtown and the Peery Park tech corridor. Both run through the same strict Planning Department. We know which side of that line your project falls on, and we plan the window work accordingly.

ES Windows Models & Products We Service in Sunnyvale

We service the ES Windows Series 2000 and 2100 aluminum sliding windows that are common original-to-1970s replacement units in Sunnyvale’s Eichler and ranch tract homes, plus the vinyl single-hung and slider replacement series, fixed/picture window units paired in multi-panel slider openings, and aluminum sliding glass door systems. We source OEM ES Windows rollers, latches, glazing beads, and replacement sashes where the series is still supported. When OEM is discontinued, we specify dimensionally matched aftermarket aluminum or vinyl units that match the existing rough opening rather than resizing the wall. If the frame and flashing are sound we repair. If the sill pan or rough opening is compromised, we push for full replacement because a patch will leak again. It’s the honest call, and it’s the one we’d make on our own homes.
