ES Windows Construction in Los Gatos, CA | Framework Contractors
We install and service ES Windows products throughout Los Gatos, from the century-old bungalows near downtown to the hillside cabins off Highway 17. What makes our ES Windows work different here is simple: we understand that Los Gatos is two distinct construction environments, and a window that performs perfectly on a flat lot in 95030 may fail prematurely on a steep 95033 slope if it isn’t spec’d and flashed correctly. We’re Framework Contractors, led by Noel Carbajal, and we’ve worked this brand in both worlds long enough to know what holds up. Call (844) 681-3590 to schedule a free estimate.
Why Los Gatos Residents Choose Us for ES Windows Service
ES Windows vinyl units are common in Los Gatos homes, and when they fail, homeowners want someone who knows the product line without having to explain it from scratch. We’ve pulled apart enough ES single-hungs, sliders, and casements in this town — including through our Lexington Hills ES Windows service — to know how their balances, locks, and glazing behave after ten or twenty years of thermal cycling. That means we diagnose faster and quote accurately the first time.
Noel Carbajal, our owner, grew up learning construction the hard way: patching stucco and reroofing porches with his uncle before he was old enough to drive, then studying Construction Technology at Santiago Canyon College. He’s spent nearly three decades building and remodeling, and he brought that same “learn the product, respect the house, don’t shortcut the flashing” approach to every ES Windows job we take on in Los Gatos. We use OEM sashes, balances, locks, and glazing when the profile is still supported, and we source quality aftermarket hardware and glass when OEM is discontinued or back-ordered.
We’re an independent outfit. Not authorized, sponsored, or warranty-endorsed by ES Windows. We service the brand because it’s what’s actually in these homes, not because anyone certified us.

Common ES Windows Construction Problems We Solve in Los Gatos
- Warped and binding sashes on south- and west-facing elevations. Los Gatos summer sun is relentless on vinyl. Add two decades of thermal cycling and ES frames on those exposures can distort enough that the sash binds in the track. We see it most in the flats around downtown, where homes sit exposed with no tree canopy. The fix is usually a new sash or a full replacement if the frame is racked.
- Fogged sealed units on the 95033 hillside. Insulated glass units on older ES vinyl windows fail when the seal breaks down and moisture gets between the panes. The 95033 side, up Highway 17 toward Redwood Estates, sees harsher UV and bigger temperature swings, and that accelerates the gassing-out. A fogged unit is a glass replacement, not a full window replacement, unless the frame itself is compromised.
- Water intrusion at the rough opening during atmospheric-river storms. Winter wind-driven rain, especially on hillside lots, pushes past aging perimeter sealant and flashing. We’ve rebuilt sill pans and rough openings on ES windows in Los Gatos where rot had already started underneath. This is the one you don’t want to ignore: water intrusion behind the cladding gets expensive fast.
- Balance and hardware failure from foundation movement. Los Gatos sits on expansive clay soil in many areas, and it moves seasonally. When a foundation settles or heaves, the window opening racks, and ES sash balances, locks, and rollers stop holding position. The window gets blamed, but often the real culprit is movement below. We fix the window and tell you what we saw underneath.
- Sliding patio door rollers and locks that no longer seal. ES sliding glass patio doors take a beating on hillside exposures. After a wet winter, the deck or stoop settles, the door falls out of square, and the rollers bind. We replace rollers, adjust the frame, and reset the lock so it actually latches and seals against the next storm.
ES Windows Service in Los Gatos: What Local Conditions Mean for Your Equipment
Los Gatos sits at the foot of the Santa Cruz Mountains, and construction here runs through two very different regulatory realities. The flats around downtown (95030 and 95032) are design-review territory: Victorians, Craftsman bungalows, and mid-century ranches on tight lots, where any window change has to pass architectural review. The 95033 mountain side, up Highway 17 toward Redwood Estates, is where we also provide ES Windows repair in Cambrian Park — a different animal entirely. Those homes straddle the Los Gatos planning-review line and Santa Cruz County’s WUI fire code, so an ES window replacement up there may need to satisfy Chapter 7A fire-resistant glazing and detailing on one side of the property line while the other side is still a Los Gatos permit. The same job can require two different sets of window and flashing specs. That’s the split reality no generic window page talks about, and it’s the reason we walk every hillside job before we price it.
Up in Redwood Estates off Highway 17 — an area we cover with ES Windows repair in Saratoga — our crew took on a hillside cabin where the ES vinyl sliders had fogged sealed units and the sashes no longer sealed against winter wind-driven rain. We pulled the failing sliding patio door and double-hungs, rebuilt the rough openings and sill pans with fire-rated detailing to satisfy the WUI side, and set new ES casement and slider units with fresh flashing and perimeter sealant. No more fogging between the panes, and the doors now lock and seal tight through the wet season. Build it right the first time; the second time costs twice as much and nobody’s happy.
ES Windows Models & Products We Service in Los Gatos
We service the full ES Windows vinyl line found in Los Gatos homes: single-hung and double-hung replacement series, horizontal sliding vinyl windows, casement and awning vinyl series, and sliding glass patio doors. For parts, our approach is straightforward: OEM first. If ES still supports the profile, we order factory sashes, balances, locks, and glazing. If OEM is discontinued or back-ordered with no clear delivery date, we use quality aftermarket hardware and glass that fits the existing frame. We keep common balance springs, rollers, and locks stocked for fast Los Gatos turnaround on the repair side. Full replacement orders are spec’d to the elevation and exposure, not just the rough opening size.
We also handle ES Windows as part of larger scopes: ES Windows sales & service sits alongside our full window and door replacement program, and we frequently coordinate window work with home additions and ADU construction. One contractor, every system. From the roof down to the foundation.

| Home Addition | $45,000 – $130,000 |
What drives the cost: number of windows, exposure (south- and west-facing hillside units get more abuse), whether the rough opening needs re-flashing or sill-pan rebuild, and whether WUI Chapter 7A detailing applies.

FAQs – ES Windows Construction in Los Gatos
If the frame is square and the rollers and lock still work, you replace the sealed unit, not the whole door. Fogging is a seal failure, and the fix is new insulated glass. If the frame is racked from hillside movement or the sill pan shows water damage, replacement is the honest call. Call (844) 681-3590 and we’ll assess it for free.
Not all of them. Chapter 7A compliance depends on the glazing package, frame rating, and installation detailing, not just the brand. Some ES units can be spec’d and installed to pass WUI review; others cannot. On the 95033 side, we verify the specific model against the fire code before we order anything.
Expansive clay moves with the seasons. When the foundation heaves in winter and settles in summer, the window openings rack, and the frames move with them. That’s why balances, locks, and rollers fail on some Los Gatos homes even when the windows themselves are sound. We fix the hardware and always note what we saw at the foundation level.
Yes, in most cases. The flats around downtown Los Gatos have strict design review, so matching profile, grille pattern, and color matters. We’ll confirm what’s still available from ES and spec the closest match that passes architectural review. If a true match isn’t made anymore, we’ll tell you before you spend a dime.
No. We’re an independent contractor. We install and service ES Windows because the brand is common in Los Gatos homes, not because we hold any manufacturer certification. That independence means our parts recommendation is based on what’s best for your house, not what a warranty program requires. Estimates are free: call (844) 681-3590.
