ES Windows Construction in Sunnyvale, CA | Daly City Construction
We handle ES Windows construction service across Sunnyvale, from sash repairs on original ranch houses to full glass-wall replacements on Eichler-era homes. The thing that sets our work apart here is simple: Sunnyvale’s mid-century housing stock was built with post-and-beam framing and single-pane glazing, so an ES Windows swap is rarely a drop-in job. It’s a framing, flashing, and drainage job. Call (866) 505-5254 and we’ll tell you what your house actually needs, not what a brochure says it needs.
Why Sunnyvale Residents Choose Us for ES Windows Service
We’ve spent years fitting, re-glazing, and re-flashing ES Windows units in Silicon Valley’s mid-century housing stock. That experience comes from the work itself, not from a dealer training session. Noel Cabrera, our owner, grew up in Daly City’s Westlake district watching his uncle re-frame a garage, and he trained in construction technology at City College of San Francisco before putting in years on residential jobs across San Mateo County. When a Sunnyvale homeowner asks whether an ES Windows unit should be repaired or replaced, the answer comes from someone who has opened up enough of these walls to know what’s behind the trim. We’re an independent crew. We work on ES Windows because they’re already in your wall, not because anyone authorized us to. Our full ES Windows sales & service work covers everything from sash balance swaps to complete window replacement, and we bring the same approach to every Sunnyvale service area job: look at the frame, check the flashing, and make the call that lasts.

Common ES Windows Construction Problems We Solve in Sunnyvale
- Failed sash balance springs and nylon tilt-latch hardware. Older ES Windows vinyl single-hungs take a beating on Sunnyvale’s west-facing ranch streets, where full afternoon sun cooks the hardware for a decade or more. The springs lose tension, the tilt latches snap, and the sash either slams down or won’t stay up. We source OEM-matched balances and latches when the profile is still available, and we replace the whole hardware set so you’re not back in the same spot next season.
- Fogged insulating glass on double-pane units. Sunnyvale’s dry-season heat cycling followed by heavy winter rain stresses glass seals, and ES Windows double-panes eventually show the telltale silica haze between the panes. Seal failure means the insulating gas is gone and the glass is doing nothing but fogging. If the frame is sound, we re-glaze. If the frame is gone, we say so.
- Water intrusion at the frame-to-wall flashing on sliders. ES Windows sliders set into flat-roof or low-slope mid-century Sunnyvale walls were often flashed thin from the start, because the original drainage detailing on post-and-beam construction was minimal. That’s not a glass problem. It’s a flashing problem. We pull the trim, re-detail the sill pan and head flashing, and fix the drainage path before it rots the framing.
- Worn weatherstripping and roller tracks on patio sliders. Decades of grit and zero service grind ES Windows patio slider rollers down to nubs, and the door binds, drags, or jumps the track. On Sunnyvale ranches where the slider is the only rear access, a stuck door is a daily annoyance. We replace rollers, clean and re-align tracks, and install fresh weatherseal so the door actually closes like it should.
- Original single-pane ES Windows units in Eichler-era glass walls. Sunnyvale’s Eichlers and tract ranches often still have their original single-pane glazing in fixed and awning configurations. Those walls were designed around slim frames and post-and-beam openings, so a straight sash replacement won’t work. We re-frame the opening or set dimensionally matched units into the existing structure, keeping the mid-century look while getting you into dual-pane glass.
ES Windows Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Sunnyvale sits at the center of Silicon Valley, where the demolished orchards of the Valley of Heart’s Delight became low-slung 1950s and 1960s tract ranches and Eichlers, many of which are now being torn down or expanded into two-story rebuilds. On streets off Fair Oaks Avenue in the 94086 ZIP, we regularly open up walls of original single-pane ES Windows glazing set into post-and-beam framing, and the job is never just a window swap. The thin-slab radiant floors and low-slope flat roofs common to mid-century Sunnyvale homes mean an ES Windows replacement has to respect shallow framing depths and drainage details that a modern stick-framed house never thinks about. Add the city’s tree-preservation and ADU review rules, which can hold a permit longer than the actual build, and you get a window job that requires a framing-and-flashing contractor, not a parts-swapper. We’ve done that exact job on an Eichler-era street off Fair Oaks: opened up a wall of original single-pane glazing, set new ES Windows sliding and fixed units into the existing post-and-beam framing, and re-detailed the low-slope sill flashing because winter rain was already tracking behind the old frames. That homeowner got a quieter dual-pane wall that kept the mid-century lines, and we replaced the worn back sliders in the same dry-season window.
ES Windows Models & Products We Service in Sunnyvale
We work on the ES Windows vinyl single-hung and double-hung replacement series, the sliding vinyl patio doors, the fixed and awning units used in Eichler-era glass-wall openings, and the horizontal slider windows common in 1950s to 1970s ranch remodels. When OEM ES Windows profiles are still available, we source OE-matched sash balances, tilt latches, rollers, and weatherseal. When they aren’t, we use dimensionally matched aftermarket glazing and hardware that fits the opening without butchering the frame. We stock the most common ES Windows hardware locally for fast Sunnyvale turnaround, and we carry dual-pane glazing options sized for the thinner mid-century wall openings that dominate the 94086 and 94087 ZIPs.

FAQs – ES Windows Construction in Sunnyvale
Yes, in most cases. We set new ES Windows fixed and sliding units into the existing post-and-beam openings without altering the structural framing, and we re-detail the sill and head flashing at the same time. The trick is matching the thinner wall depth of mid-century Eichler construction, which we’ve done on multiple Sunnyvale streets. Call (866) 505-5254 and we’ll look at your wall before we recommend anything.
If the frame is sound, we repair both: source a new balance spring and tilt-latch set, and re-glaze the fogged sash with fresh dual-pane glass. If the frame or the glass seal is gone, especially on a unit set in a thin-slab Eichler wall, we tell you straight that replacement is the better spend. Call (866) 505-5254 for a free assessment and a line-item quote.
Not always, but it usually makes sense. If the existing first floor has ES Windows units in good condition, matching the profile and glazing style keeps the house from looking patched together. We can source ES Windows units for the new upper floor and set them in the same way we’d set the originals, with proper flashing on the new framing. Call (866) 505-5254 and we’ll talk through what your addition actually needs.
Straight window replacement on an existing opening usually moves fast. But if the job involves resizing openings or adding glazing as part of a second-story addition or ADU, Sunnyvale’s building division and tree-preservation review can stretch the permit process longer than the install itself. We handle the paperwork and plan around the dry-season window. Call (866) 505-5254 to get started early enough to avoid the winter rain.
Yes. ES Windows patio sliders work well for a Sunnyvale kitchen remodel that opens to a backyard, especially when the existing rear wall is a low-slope or flat-roof mid-century wall. We set the slider with re-detailed sill flashing so winter rain stays outside, and we replace the roller track so the door glides. Call (866) 505-5254 for an exact quote on your kitchen-and-slider scope.
