ES Windows Construction in Sunnyvale, CA | Bradford Remodeling Co San Jose
We provide independent ES Windows installation, replacement, and repair across Sunnyvale, and our work here is shaped by one local fact: most of the homes we touch are 1950s – 70s tract builds now being gutted, lifted, or replaced outright for Kitchen Remodeling - Sunnyvale projects and more. That means we spend as much time salvaging well-built ES frames on original Eichlers and Birdland ranchers as we do installing new ES 8000 Series glass on two-story teardown replacements. If you need straight pricing on ES window work in Sunnyvale, call (669) 272-2637. We write the scope, we name the number, and we stand behind the work for a full year.
Why Sunnyvale Residents Choose Us for ES Windows Service

We know ES Windows the way a mechanic knows a specific engine family. Not because we sell them, but because we’ve rebuilt enough of them across San Jose and Sunnyvale to know exactly where they fail and what fixes actually last. Curtis Lane runs our operation, and he learned to read a window opening down to the rough framing before he ever picked up a finish hammer. He trained through the construction technology program at Los Angeles Trade-Technical College, and he’s carried that by-the-numbers approach into every ES job we take in Sunnyvale.
We’re an independent ES Windows service team, not a manufacturer-authorized dealer. That matters because we recommend what the house needs, not what moves inventory. On a 1963 rancher in Sunnyvale with original ES 3000 Series sliders, we’ll tell you when the aluminum frame is square enough to justify new insulated glass units. On a 2021 two-story replacement near Ortega Park, we’ll tell you when the ES 8000 Series units are still under warranty and only need a roller and lock service. We also carry or can source genuine ES glazing beads, rollers, and locks for newer units, and we use spec-matched aftermarket seals and hardware for discontinued ES 3000 and 6000 series parts that ES no longer stocks. Every job gets a written price before work starts. No numbers that move at the door.

Common ES Windows Construction Problems We Solve in Sunnyvale
- Fogged dual-pane glass from seal failure in original ES insulated units. Sunnyvale’s winter rain and summer dry-heat cycles work the seals on 50- and 60-year-old ES glass until moisture gets between the panes. We replace the insulated glass unit when the frame is still square, which often means keeping the original aluminum and avoiding stucco work.
- Warped or bent aluminum sashes on large ES slider doors. Sunnyvale’s clay-heavy soils expand and contract with moisture, and on Birdland ranch homes that foundation movement can rack an ES sliding door frame until the panels bind. We re-level the rough opening, swap worn rollers and track, and reset the door so it moves again.
- Worn rollers and failed locks on ES sliding patio doors. After decades of daily use, original ES rollers flatten and locks stop engaging. On teardown-prepped homes in Sunnyvale this is often a security question as much as a glide question, and we replace both with parts that match the original spec.
- Corroded aluminum frames at weep holes on ES horizontal sliders. Homes near Sunnyvale’s seasonal creek areas see moisture wick into the frame channels, and when weep holes clog or corrode, water finds the drywall instead. We clear, repair, and reseal those channels before the next rainy season.
- Discontinued ES 3000 and 6000 series hardware failures. Locks, keepers, and roller assemblies for these older lines are no longer made by ES. We source aftermarket equivalents that match the original dimensions and load ratings, so a broken lock doesn’t force a full window replacement.
ES Windows Service in Sunnyvale: What Local Conditions Mean for Your Equipment
If you own a 1960s ranch in Sunnyvale’s Birdland neighborhood, there’s a hidden cost most out-of-town crews don’t know to look for. Original homes there were commonly built with asbestos-cement siding, and California law requires abatement before any window or door opening can be modified. That means a straightforward ES window replacement can turn into a two-phase job: abatement first, then new or repaired windows, with the timeline and permit path changing accordingly. We flag it during the estimate so you’re not surprised on demo day. This is the kind of thing you only learn by working Sunnyvale jobs year after year. The clay soil here compounds it, because slabs settle and shift, and an ES slider that was square in 1965 may be racked by 2025. We’ve seen it on W. Remington Drive: a fogged ES 6000 Series four-panel sliding door and two matching ES 8000 picture windows on a 1963 rancher. The clay had settled under the slab, the door panels seized, and we had to re-level the rough opening, replace the rollers and lower track with aftermarket equivalents, and reset the glazing on the picture windows. The homeowner kept the original ES frames, and we sealed the new insulated glass with a spacer matching the originals’ 7/8-inch profile, avoiding any stucco touch-up. That’s the difference between a crew that reads Sunnyvale houses and one that just replaces glass.
ES Windows Models & Products We Service in Sunnyvale
We work on the full ES Windows catalog that shows up in Sunnyvale homes: the ES 3000 Series aluminum with thermal break, the ES 6000 Series heavy commercial aluminum often spec’d on larger sliding doors, the ES 8000 Series dual-glazed high-performance units on newer builds, and the ES ESW Series wood-clad aluminum on higher-end remodels. For newer units under warranty, we source genuine ES replacement parts for glazing beads, rollers, and locks so the original fit and coverage stay intact. For discontinued ES 3000 and 6000 series, we use high-quality aftermarket seals and hardware that match the original specifications. We stock common roller and lock sets locally for fast Sunnyvale turnaround, and we’re honest about when a fogged insulated glass unit is worth replacing versus when a warped frame means a full window replacement is the smarter money. If you need ES Windows sales & service, we’ll tell you straight which path costs less over five years.

FAQs – ES Windows Construction in Sunnyvale
Are ES Windows still being made, or do we need to replace our Sunnyvale home’s original units with a different brand?
ES Windows is still manufactured, and many current lines are available for replacement projects. If your Sunnyvale home has original ES 3000 or 6000 Series units from the 1960s or 70s, those specific series are discontinued, but the frames can often be kept and re-glazed with new insulated glass. Call (669) 272-2637 and we’ll tell you after looking at the frames whether it’s a repair or a replacement job.
Does Bradford Remodeling Co San Jose handle asbestos siding removal before replacing ES windows on 1960s Sunnyvale homes?
We coordinate the abatement with licensed asbestos contractors, but we do not perform the abatement ourselves. If your Birdland-era Sunnyvale home has asbestos-cement siding, that work has to happen before we can modify any window opening, and we’ll include it in the project timeline and written scope from day one. Call (669) 272-2637 for a straight estimate on the full job.
Why do ES sliding patio doors in Sunnyvale often stick or drag, and can that be fixed without replacing the whole door?
Sunnyvale’s expansive clay soil settles and shifts, and over decades that movement racks the door frame until the panels bind. In most cases we re-level the rough opening, replace the rollers and lower track with spec-matched parts, and the door glides again without replacing the whole assembly. If the frame itself is corroded or badly warped, we’ll tell you that a replacement is the cheaper long-term fix.
What’s the typical cost to fix a fogged ES dual-pane window in Sunnyvale, and is it worth it on an older home?
A fogged insulated glass unit repair runs $300 – $900 per window when the aluminum frame is still square. On a 1960s Sunnyvale home with original ES frames, replacing the glass unit is usually the better move than regassing, because the seal has already failed and regassing won’t restore it. Call (669) 272-2637 and we’ll price it by the window, in writing, before any work starts.
Do ES Windows hold up in Sunnyvale’s climate, especially for homes adding second stories or ADUs?
ES Windows handle Sunnyvale’s dry summers and winter rains well when installed correctly, but clay-soil foundation movement is the real enemy here. On two-story additions and ADUs, we spec ES units with proper flashing and account for slab movement at the rough opening so the frames stay square. For older homes getting a second story, the original single-story ES windows usually need to be replaced anyway to meet current energy and structural requirements.
