ES Windows Construction in Cupertino, CA | Viceroy Construction
We provide independent ES Windows service across Cupertino’s 95014 and 95015 ZIP codes, and the specific reason homeowners call us here more than anywhere else is simple: Cupertino’s housing stock is packed with 1950s-70s ranch homes and Eichler-era builds whose original ES Windows units are now hitting the end of their service life under valley heat cycles, clay-soil settling, and WUI-driven glazing requirements. We install, repair, and replace ES Windows aluminum sliders, vinyl single-hungs, fixed picture units, and horizontal sliders without pushing a full replacement when a re-track, re-seal, or re-glaze will do the job. Call (877) 358-6557 to schedule a free ES Windows estimate in Cupertino.
Why Cupertino Residents Choose Us for ES Windows Service
We’re a full-scope general contractor, not a window shop that sends a sales rep to measure and a sub to install. When we work on ES Windows in Cupertino, the same crew that reads the shop drawings and glazing specs also handles the flashing, the stucco repair, and the rough-opening correction if the wall has racked out of square over decades of clay-soil movement. Neil Drummond grew up in the Saratoga foothills and has spent the better part of three decades working construction across the South Bay, so he’s walked the same Eichler-era floorplans and 1970s ranch additions you live in. That’s why our ES Windows sales & service work starts with an honest assessment of what’s actually failing, whether it’s the glass, the track, the flashing, or the wall framing itself.
Cupertino homeowners tend to be permit-savvy. They’ve already pulled the city’s protected-heritage tree reports or run the WUI glazing check by the time they call us. We respect that. We come ready to talk Chapter 7A compliance, arborist fencing requirements, and whether your existing ES Windows frames are even worth saving, or if you need ES Windows repair in Los Altos instead, before you spend $15,000 on a replacement wall.

Common ES Windows Construction Problems We Solve in Cupertino
- Slide-track and roller wear on ES Windows aluminum sliding glass doors. In Cupertino’s 1950s-60s ranch remodels, original door tracks often carry sixty years of grit. Panels stop gliding, latches stop engaging, and homeowners assume the whole door is shot. Usually it’s a roller and track hardware replacement, not a new door.
- Perimeter seal and flashing failure on ES Windows vinyl single-hungs. Winter gully-washers in Cupertino push wind-driven rain against west-facing window walls. When the original flashing was flashed to 1960s building paper, the seal fails and water shows up as drywall staining and stucco bubbling at the rough opening. We open the wall, re-flash properly, and reseat the window.
- Glazing seal (IGU) fogging on south- and west-facing ES Windows picture and awning units. Cupertino’s dry summers mean long solar load on unprotected glass. Insulated glass unit seals break down, and the window clouds from inside. The fix is a glass swap, not a frame replacement, if the frame and install plane are still sound.
- Sliding-window latch and screen-track misalignment on ES Windows horizontal sliders. As 1970s-era wall framing settles or a whole-house remodel shifts load paths, the install plane racks out of square. Latches no longer line up with keepers, screen tracks bind, and the fix is re-shimming and reinstalling the unit square, not replacing it.
- Full unit replacement when it’s genuinely warranted. When a 30-year-old ES Windows unit has corroded frames, failed glazing, and a rough opening that’s moved beyond shimming, we say so plainly. We won’t oversell replacement on a sound frame, and we won’t pretend a dead unit can be saved.
ES Windows Service in Cupertino: What Local Conditions Mean for Your Equipment
Cupertino’s protected-heritage tree ordinance and dense mature canopy mean something specific if you own ES Windows: your window schedule often can’t even be permitted until an arborist report and tree-protection fencing are in place. The city doesn’t let you cut roots or drop branches to make way for a new window wall without paperwork. And behind those openings, the flat, clay-heavy valley-floor soils are where expansive-soil movement shows up as out-of-square rough openings after a rebuild or addition. So when we install ES Windows in Cupertino, we’re not just setting a frame in a hole. We’re squaring the rough opening, correcting for the soil movement that’s been happening under that fifty-year-old wall, and working around the tree roots the city has protected. That’s not true in Campbell, ES Windows service in Saratoga, or Los Gatos to the same degree. It’s the cost of doing window work in a city that values its canopy as much as its square footage.
On a ranch-plus-addition remodel near the Monta Vista area, our crew took on a wall of ES Windows aluminum sliding glass doors whose 1960s rollers had bound up in a grit-packed lower track and whose latches no longer engaged. We pulled the panels, replaced the rollers and track hardware, re-seated the glazing, and re-flashed the perimeter before the renewed stucco went on. The units glide and lock cleanly again without a full door replacement. Along the way we flagged one south-facing fixed unit with a fogged IGU and swapped just the glass, since the frame and install plane were still sound. The details you don’t see are the ones that matter most, and on that job the detail was a 60-year-old lower track full of decomposed granite and oak duff.
ES Windows Models & Products We Service in Cupertino
We work on the full ES Windows residential lineup common in Cupertino homes: aluminum sliding glass doors, vinyl single-hung windows, fixed picture and awning window units, and horizontal sliding windows. For parts, we order OEM ES Windows rollers, latches, weatherstripping, and glazing when the supply chain allows. When OEM lead times stretch out, we match to spec-grade aftermarket hardware so our Cupertino customers aren’t waiting six weeks for a door that should take three days. If you’re mid-remodel and the window schedule is holding up your stucco, we can get most ES Windows in Sunnyvale and Cupertino moving within the same week, not the same quarter.

What drives the cost on ES Windows work in Cupertino is the rough opening, not the window itself. If we’re working around a protected heritage tree, squaring a shifted opening, or re-flashing to Chapter 7A requirements, that labor shows in the number. If the opening is square and the original frame is salvageable, a repair stays at the low end. Every estimate is free, written, and line-itemed so you see exactly what’s repair, what’s replacement, and what’s tied to Cupertino-specific compliance. Call (877) 358-6557 to get yours.

FAQs – ES Windows Construction in Cupertino
Yes, in most cases. If the rollers are bound and the track is packed with grit but the frame and glass are sound, we replace the rollers and track hardware and re-seat the door. Replacement is for when the frame is corroded or the rough opening has moved beyond correction. Call (877) 358-6557 and we’ll tell you which one you’re looking at.
We install ES Windows units to meet Cupertino’s wildfire-interface standards, which means Chapter 7A glazing and materials where the city requires them. Our crews understand the difference between a standard unit and a WUI-compliant one, and we specify accordingly so your permit doesn’t get bounced back. The right glass and frame spec is the difference between passing inspection the first time and redoing the whole opening.
Usually it’s the flashing. The window unit itself is rarely the leak point on a single-hung; the failure is at the rough opening where the original installation flashed to outdated building paper. We open the wall, find the actual water path, and fix it at the source. That’s the kind of repair most window replacement companies won’t touch because they’d rather sell you a new unit. We’d rather fix the leak so your new window actually works, if you need one at all. Call (877) 358-6557 for a leak assessment.
For a typical single-unit replacement in an already-open wall, we can complete the swap, re-flash, and interior trim the same day. For a multi-unit wall or a door wall on a remodel, you’re looking at two to five days depending on the rough opening and any stucco or drywall work that has to follow. We keep the schedule tight because your other trades are usually waiting on the windows to close up the wall.
Yes. That’s a failed insulated glass unit, and the fix is a glazing swap, not a new window. We order the replacement IGU, pull the old glass, and re-seat the new glazing into the existing frame if it’s still square and sound. It’s a fraction of the cost of a full replacement, and you keep the original aluminum frame that matches the rest of the house. Call (877) 358-6557 and we’ll confirm the IGU size and get the glass on order.
