ES Windows Construction in Cupertino, CA | San Bruno Construction
We provide independent ES Windows construction service across Cupertino, with deep familiarity in the Series 3000 through 8000 product lines. The one difference here is permits: Cupertino’s planning department treats window work on second stories and additions differently than any neighboring city, and we sequence every job around that reality. Call (866) 472-1908 for a free estimate on ES Windows replacement, impact installation, or full-home window packages in the 95014 and 95015 ZIP codes. We’re not manufacturer-affiliated, and that independence means we repair when it makes sense and replace when it doesn’t.
Why Cupertino Residents Choose Us for ES Windows Service
Noel Carvalho, our owner, trained in construction technology at Skyline College and has spent two-plus decades running residential projects across the South Bay. He reads plans, understands load paths, and knows what a Cupertino inspector will flag before the inspector even shows up. That matters when you’re dealing with ES Windows units in a 1950s ranch where the original flashing has been failing for thirty years.
We’ve provided ES Windows repair in Los Altos and serviced these products in hundreds of local homes. We know which Series 8000 units hold up on west-facing walls and which Series 5000 sliders start sticking when the clay soil underneath shifts. We stock common OEM parts for faster turnaround, and when a discontinued line means OEM isn’t available, we source aftermarket components that meet or beat the original spec. You get one contractor who coordinates the entire job, from pulling the permit to final trim, rather than a window vendor and a separate general contractor pointing fingers at each other.

Common ES Windows Construction Problems We Solve in Cupertino
- Dry-rot and water infiltration at sill and frame joints. This is the number one issue we see in 1950s – 1970s ranch tracts across the 95014 flats. Original flashing was often inadequate, and Cupertino’s hot, dry summers bake sealant until it cracks and separates. Water gets in, wood rots, and the frame quietly deteriorates behind the stucco. We cut out the rot, reframe as needed, and install the new ES Windows unit with proper modern flashing.
- Fogging and seal failure in dual-pane insulating glass. After 15 – 20 years, many ES Windows IGUs lose their seal, especially on south- and west-facing elevations that take direct sun through Cupertino’s long dry season. The valley’s daytime-to-night temperature swings stress the seal flex point. We replace the insulated glass unit when the frame is sound, and recommend full replacement when multiple seals on the same wall have failed.
- Hardware failure: corroded rollers, hinges, and locks. West-facing sliding and casement models take wind-driven dust from the Santa Cruz Mountains foothills and occasional winter rain. Rollers bind, locks corrode, and operation gets stiff and noisy. We replace hardware with OEM or high-grade aftermarket parts and realign the sash so the window actually operates smoothly again.
- Sticking or difficult operation from soil settlement. Cupertino’s expansive clay soils move with the seasons, and hillside lots in the eastern hills with retaining walls shift even more. ES Windows aluminum and vinyl frames can rack slightly, causing sashes to bind. We don’t just force the window; we check the opening, the header, and the foundation movement pattern, then correct the installation so the new unit operates cleanly.
- Leak paths around second-story additions. When a ranch gets a second story added, the original first-floor window headers weren’t designed for the new structural loads. We see ES Windows units under added-structure weight cracking at the corners or pulling away from the flashing. We address the frame condition before the window goes in, not after the drywall is patched.
ES Windows Service in Cupertino: What Local Conditions Mean for Your Equipment
Cupertino’s planning department requires a heritage-tree assessment and neighbor notification for most second-story additions and new builds. That’s not boilerplate, it’s a hard gate: the city scrutinizes tree removal, grading, and two-story massing far more closely than ES Windows in Sunnyvale or San Jose. For ES Windows projects, it means window placement and glazing often have to be adjusted to satisfy privacy and tree-preservation conditions. You can’t just put a Series 8000 picture window wherever the framing allows. If a protected oak sits six feet from the proposed opening, the city may push the window to a different wall or require obscure glazing on a certain elevation. We’ve been through this enough times in the ranch tracts near the old orchards that we build those realities into our bids upfront. A contractor who doesn’t know Cupertino’s heritage-tree rules will sell you a window layout that dies in plan check, and you’ll eat the redesign cost.
ES Windows Models & Products We Service in Cupertino
We work on the full ES Windows range: Series 3000, Series 5000, Series 7000, and the flagship Series 8000. Each line has different frame profiles, glazing options, and hardware sets, and we stock replacement parts accordingly. For discontinued lines where OEM parts are no longer manufactured, we source aftermarket components that match or exceed the original specifications. Our repair-vs-replace stance is straightforward: if the frame and glass are sound, we repair. If multiple seals have failed or the frame is compromised by rot or settlement, we recommend full replacement with a modern ES Windows system. We also sell and install new ES Windows units, which you can read more about on our ES Windows sales & service page.

FAQs – ES Windows Construction in Cupertino
Yes, in most cases. Cupertino requires permits for window replacement when the opening size changes, when structural work is involved, or when the work is part of a larger addition or remodel. Straight same-size replacement may qualify for an over-the-counter permit, but we always verify current requirements with the Cupertino building department before starting. Call (866) 472-1908 if you want us to check your specific situation.
A standard single-window replacement is typically one day of on-site work. A full-home window package in Cupertino usually takes three to seven working days, depending on how many units, whether scaffolding is needed for second-story work, and whether the city requires heritage-tree or privacy reviews that add plan-check time, unlike ES Windows service in Saratoga. We’ll give you a realistic schedule before the project starts.
Yes, if the frame is sound. We replace the failed insulated glass unit with a new one matching the original spec. If multiple seals on the same wall have failed, or if the frame shows rot or settlement damage, we’ll recommend full replacement instead, because patching a failing system costs more over time. Call (866) 472-1908 for an inspection and an honest recommendation.
Yes, when specified correctly. ES Windows low-E glazing options reduce solar heat gain during Cupertino’s hot, dry summers, and impact-rated models can provide hardening against wind-driven embers from the western foothills. We help you choose the glazing package and frame spec that fits your exposure and the city’s current wildfire-hardening guidance.
Most Cupertino ES Windows replacement projects fall between $4,500 and $15,000, depending on unit count, size, glazing upgrades, frame condition, and whether the city requires heritage-tree or privacy reviews that add plan-check time. Impact-rated units run $8,000 – $25,000. Estimates are free and line-item specific. Call (866) 472-1908 for an exact quote.
