ECO Window Systems Construction in Sunnyvale, CA | Workshop Contractors
We’re an independent general contractor that installs, repairs, and replaces ECO Window Systems units across Sunnyvale’s 94085, 94086, 94087, and 94088 ZIP codes. What makes our ECO work different here is that we understand how Sunnyvale’s teardown-and-rebuild economy stresses windows in ways a generic installer never sees: new two-story neighbors casting shade on old glass, expansive clay shifting slabs under patio sliders, and Title 24 energy rules that bite every remodel. Call (844) 384-3361 for a free estimate on any ECO window or door job.
Why Sunnyvale Residents Choose Us for ECO Window Systems Service
We’ve spent years pulling failed ECO units out of Sunnyvale’s 1950s and 1960s ranch bungalows and putting new ones into contemporary infill builds. That’s not the same thing as being an “authorized” dealer, and we’re not going to pretend it is. We’re a licensed general contractor, independent of ECO Window Systems, and the value we bring comes from having our hands on enough of these units to know exactly how their frame profiles, glazing packages, and hardware behave under real Santa Clara County conditions. Noel Figueroa, our owner, grew up watching tradesmen frame houses on his street and learned the fundamentals at Chaffey College’s construction technology program before spending decades working from the Inland Empire up through the Bay Area. His rule has always been: build it right the first time. The second time costs twice as much and nobody’s happy about it. That’s how we approach ECO work in Sunnyvale, whether it’s a fogged-glass replacement on an orchard-tract ranch in 94087 or a fresh slider on a two-story rebuild in 94086. For a full look at what we do, see our ECO Window Systems sales & service page.

Common ECO Window Systems Construction Problems We Solve in Sunnyvale
Sunnyvale’s particular mix of old housing stock, dry summers, winter rain, and aggressive infill construction creates repeat patterns in the ECO failures we fix. Here are the five we see most often:
- Fogged dual-pane glass on west and south elevations. The dry summer sun bakes unshaded glass on Sunnyvale’s west-facing bungalow walls, and eventually the insulated glass unit seal fails. You get condensation between the panes and a window that no longer insulates. We replace the IGU and re-spec the glazing so it holds up.
- Sticking or hard-to-latch sliding patio doors. Sunnyvale’s expansive clay soils shift with the seasons, and on older ranch homes that means the slab under the slider moves a fraction of an inch. Suddenly the door won’t latch. We reset and re-flash the slider frame, then replace rollers and hardware so it seats properly.
- Water intrusion at frame-to-wall junctions. Many 1950s and 1960s bungalows in Sunnyvale still have original flat-stucco or wood-sided walls with flashing that was never upgraded when a prior replacement window went in. Winter rain drives moisture behind the frame. We pull the unit, re-flash the opening properly, and reinstall.
- Degraded weatherstripping and glazing gaskets. On older ECO units, the rubber and felt strips that seal the sash break down after years of dry heat. Wind-driven winter rain pushes past them. We replace the weatherstripping and gaskets, or if the frame is too far gone, we tell you straight that replacement is the better spend.
- Frame bowing on long aluminum fixed-picture windows. Sunnyvale’s contemporary infill builds favor large fixed glass, and when aluminum frames are undersized or poorly supported, they bow. That compromises the seal and the sight line. We address it at the framing stage on new construction and with reinforcement on remodels.
ECO Window Systems Service in Sunnyvale: What Local Conditions Mean for Your Equipment
In the old orchard-tract blocks of 94087, you’ll see a 1950s ranch sitting directly beside a brand-new three-story build, and that neighbor’s height changes everything about how your windows perform. A west- or south-facing wall that used to bake in full sun is now shadowed for part of the day, which sounds helpful but actually accelerates condensation on older dual-pane units by trapping cooler, moisture-laden air against glass that no longer gets the dry heat that used to evaporate it. We took on a 1960s ranch in exactly that situation: the original ECO vinyl single-hungs had fogged IGU units on the west side, and a sliding patio door wouldn’t latch after the slab settled. For similar work, see ECO Window Systems in Santa Clara. We replaced the failed insulated glass units, reset and re-flashed the slider into the stucco wall, and swapped worn rollers and weatherstripping. The homeowner got clear glass and a door that seals before winter rain. That’s the Sunnyvale-specific reality: shadowing new construction, older frames, and shifting clay all interact, and you need someone who reads the whole block, not just the window.
ECO Window Systems Models & Products We Service in Sunnyvale
We work on the full ECO Window Systems lineup that’s common in Sunnyvale homes, including the vinyl single-hung replacement series you see on mid-century ranches, the sliding patio door systems that open onto backyard slabs, the casement and awning series used in wind-exposed corners, and the aluminum fixed/picture window units that dominate contemporary infill builds. When it comes to parts, we source genuine ECO replacement sashes, glass units, rollers, and hardware when available. When OEM lead times stall a job, we use quality aftermarket weatherstripping, rollers, and glass that meet or exceed the original spec. If a unit is beyond about 15 to 20 years old or the frame is bowed and leaking, we tell you straight that replacement beats repeated repair. Serving all of Sunnyvale, including Sunnyvale service area coverage across 94085 through 94088.

AfterECO Window Systems Service Pricing in Sunnyvale
Here’s what Sunnyvale homeowners can expect to budget for ECO window and door construction work. These are the ranges we quote from, and your exact price depends on the number of units, the frame condition, and whether we’re working on an existing opening or cutting into a new wall.
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
What drives the cost? For window replacement, it’s the glazing package, frame material, and whether the existing opening needs re-flashing. Impact windows add structural reinforcement and laminated glass, which is why they run higher. A home addition is a different animal entirely, with framing, roofing, and Title 24 compliance all in play. Every estimate we write is line-itemed, and the estimate itself is free. Call (844) 384-3361 to get yours.

FAQs – ECO Window Systems Construction in Sunnyvale
Yes. Matching new ECO vinyl single-hungs to original 1960s openings is the most common request we get in 94086 and 94087. We match frame profiles, glass tint, and sight lines so the new units read as original, and we re-flash the openings while we’re in there. Call (844) 384-3361 for a free estimate on a full or partial replacement.
Sunnyvale’s expansive clay soils shrink in the dry months and can drop a slab edge just enough to bind the slider track. It’s a slab movement issue, not a door hardware failure, and the fix is to reset and re-flash the slider frame, then replace rollers and hardware so the door seats and latches properly. Call us at (844) 384-3361 and we’ll diagnose it on site.
Yes, and this is where we earn our keep. Title 24 energy compliance applies to any window we install on a permitted Sunnyvale Home Remodeling or new build. We spec glazing packages and frame materials that clear the standard, and we pull all permits so the inspection passes the first time.
In most cases, yes. Fogging means the insulated glass unit’s seal has failed. If the frame is still square and sound, we replace the IGU and the window is clear again. If the frame itself is bowed or the window is past about 20 years old, replacement is often the smarter spend and we’ll tell you that plainly.
We do it regularly. Contemporary infill builds in Sunnyvale call for aluminum fixed/picture windows and casement units, and we handle the framing, flashing, and Title 24 compliance as part of the build. Because we’re our General Contractor in Sunnyvale, we can carry the window package alongside the rest of the exterior envelope, one contract and one schedule.
