ES Windows Construction in Hillsborough, CA | San Bruno Construction
We’re an independent general contractor that installs, replaces, and services ES Windows units across Hillsborough, and we’re not manufacturer-affiliated. That means our read on your windows comes from what the building actually needs, not what a dealer is required to push. Hillsborough estate work has taught us to read glazing, flashing, and drainage together, because on these lots a window problem is usually a water problem. Call (866) 472-1908 to schedule a free estimate with Noel Carvalho and our crew.
Why Hillsborough Residents Choose Us for ES Windows Service
Hillsborough homes are not a place for guesswork. These are large, custom-built estate houses on steep wooded lots, and a window that isn’t flashed right on a hillside wall will show itself within one rainy season. We’ve worked on enough early-to-mid-20th-century Mediterranean and Tudor homes here to know exactly where ES Windows units fail and why. Noel Carvalho grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, then spent over two decades running residential projects across San Mateo County, including ES Windows service in San Mateo and Hillsborough. That background means our crew reads plans, understands load paths, and coordinates staging on narrow winding roads before a single tool comes out of the truck.
We work with ES Windows sales & service at the level a general contractor should: OEM parts where the unit is still serviceable, quality aftermarket sealed units and rollers where OEM is slow, and full replacement only when the frame or flashing detail is the actual source of the leak.

Common ES Windows Construction Problems We Solve in Hillsborough
- Fogged, failed dual-pane sealed units. On older Hillsborough estate homes, 1990s-era ES Windows replacements now face west sun through redwood and oak canopy. The silica desiccant saturates, the pane hazes, and the glass has to come out. We source matched sealed units and swap them without disturbing the surrounding stucco.
- Weathered perimeter seals and failed glazing putty on aluminum frames. Wind-driven winter rain tracks behind the frame and into stucco and sheathing on steep hillside walls. This is the one that shows up as interior staining weeks after the storm, and it’s usually a flashing and seal problem, not a glass problem.
- Slider and sliding-door track corrosion and roller wear. Grit off long private driveways and hillside runoff chew up tracks so panels rack and no longer seal. We re-roller the panels, clean and realign the track, and replace worn guide blocks so the door actually seals again.
- Water intrusion at head and sill flashing. Many ES Windows units on older Hillsborough houses were set into Mediterranean and Tudor stucco without a proper drainage plane or backer rod. When wet winters hit, water finds the gap. We pull the unit, rebuild the sill and head flashing, and reset it so water drains outward instead of inward.
- Sticking or binding sliders on settling hillside homes. Steep lots move. A panel that locked smoothly fifteen years ago now binds because the opening has shifted a fraction. We re-square and shim the frame, replace rollers, and restore smooth operation without forcing the unit.
ES Windows Service in Hillsborough: What Local Conditions Mean for Your Equipment
There’s a step in Hillsborough ES Windows work that simply doesn’t exist in unincorporated county work next door. The town runs its own design-review and building department, and on wooded hillside lots, window replacements and additions often trigger arborist review of root zones and a town sign-off on the opening before you can legally swap glass. On a steep tree-shaded lot off a narrow winding Hillsborough street, our crew replaced a bank of fogged ES Windows aluminum sliders where the tracks had corroded and winter runoff was staining the interior stucco. We pulled the units, rebuilt the sill and head flashing with a proper drainage plane, and set new sealed units with fresh rollers so the panels sealed and opened cleanly again. Hauling the old glass down the driveway was scheduled around a neighbor’s access and the town’s staging conditions before we started. If you’re replacing windows on a Hillsborough estate lot, the permit and tree review is part of the actual scope of work, not an afterthought.
ES Windows Models & Products We Service in Hillsborough
We service the ES Windows configurations most common on Hillsborough homes: aluminum single-hung and horizontal slider units, vinyl double-hung replacement windows, fixed and casement picture-window setups, and ES Windows sliding glass door systems. For OEM parts, we source ES Windows sash, hardware, and glazing where the unit is still serviceable. When OEM is slow or discontinued, we spec quality aftermarket sealed units and rollers that match the existing sightlines. Our repair-or-replace stance is simple: if the frame is sound we repair, reseal, reglaze, and re-roller. We only push full replacement when the frame or flashing detail is the actual source of the leak.

FAQs – ES Windows Construction in Hillsborough
Often yes. Hillsborough runs its own building department and design-review process, and on wooded hillside lots, window replacements can trigger arborist review of root zones and a town sign-off on the opening. This is a step that doesn’t exist in ES Windows repair in Highlands-Baywood Park or other unincorporated county work next door. We coordinate the town process as part of the job. Call (866) 472-1908 and we’ll check your specific address against the current requirements.
Usually repair. Fogged dual-pane units on older ES Windows sliders mean the sealed unit has failed and the silica desiccant inside has saturated. Gritty tracks mean roller wear from driveway runoff. Both are repairable: we replace the sealed unit, clean and re-roller the track, and reset the panel. If the frame or flashing is the source of the problem, then we’ll recommend replacement, but we don’t push it when the frame is sound. Call (866) 472-1908 for an exact quote.
Wind-driven winter rain is tracking behind the frame because the perimeter seals, glazing putty, or sill flashing has failed. On steep hillside walls, water running down stucco finds any gap at the head or sill and follows it into sheathing. We pull the unit, rebuild the head and sill flashing with a proper drainage plane, and re-seal the frame. That usually solves the leak in one visit.
Yes. We’ve matched ES Windows aluminum sliders and fixed picture windows into existing openings on Hillsborough estates, including installations where the original unit was set into Mediterranean stucco without a drainage plane. We source OEM or matched aftermarket units, re-frame the opening where necessary, and re-flash so the new unit drains properly. The goal is a window that looks like it was always there.
Mature oak and redwood canopy shades the glass, which changes how the unit heats, cools, and seals. It also means the town’s tree-preservation rules and arborist review can affect whether we can enlarge or relocate an opening without root-zone disturbance. We plan the placement and the permit steps together. Call (866) 472-1908 for an estimate, and we’ll factor the canopy and root zones into the quote.
