ECO Window Systems Construction in Los Altos, CA | Framework Contractors
We provide independent ECO Window Systems construction and replacement service across Los Altos, including the 94022, 94023, and 94024 ZIP codes. The one thing that makes our ECO work different here is that we understand how this city’s 45% lot-coverage cap and design review process shape almost every window decision. When a simple repair turns into a permit-triggering replacement because of a foothills glazing rule, we’ve already been through it. Call (844) 681-3590 to talk through your project.
As a full-scope general contractor, Framework Contractors handles window replacement alongside kitchens, bathrooms, roofing, and home additions. We also offer ECO Window Systems sales & service as one part of that larger picture. When it makes sense to repair, we repair. When Los Altos rules push you toward replacement, we handle the design review paperwork too.
Why Los Altos Residents Choose Us for ECO Window Systems Service
We’ve spent years pulling and re-glazing ECO Window Systems in Loyola and across Los Altos, so we know how their frames behave when they’ve baked in Peninsula sun for four decades. We are an independent contractor, not authorized, endorsed, or warranty-backed by ECO Window Systems, and that’s exactly why our advice stays honest. If a frame is still true and only the hardware failed, we’ll tell you to repair it. If that vinyl sill has warped past the point of sealing, we won’t pretend a new weatherstrip will fix it.
Noel Carbajal, our owner, grew up patching stucco and reroofing porches with his uncle, and he’s spent the better part of three decades in residential construction. His rule on replacement jobs applies here: if the client is going to live with a window for another thirty years, the opening has to be square, flashed, and sealed like it’s the only one we’re doing. We carry that standard into every ECO Window Systems job in Los Altos.

Common ECO Window Systems Construction Problems We Solve in Los Altos
- Dragging or jumping aluminum sliders: Original ECO aluminum sliders in 1960s Los Altos ranches lose their roller tracks over time and start dragging or jumping the rail, so they no longer latch. We rebuild the roller assemblies and straighten the track channels where the frame is still sound. When the track is pitted through, we’re honest about replacement.
- Chalked, yellowed, or warped vinyl frames: Vinyl frames on west- and south-facing units take decades of direct sun, and in Los Altos the UV load is steady most of the year. Frames chalk, yellow, and warp at the sill, which lets the sash rack out of square. A racked vinyl frame usually means replacement, not repair.
- Fogged or failed dual-pane glass: Single-glazed ECO units and older dual-pane units with failed IGU edge seal are common in original Los Altos ranch homes. In foothills-edge homes that sit inside the wildland-urban interface, fogged or failed glass is also a fire-resistant glazing gap that needs attention before the next fire season.
- Clogged weep and drainage channels: Corroded aluminum weep channels clog with dust and pollen, so winter rain backs up and stains the interior sash track. We clean and ream the drainage paths, and where the aluminum has corroded through, we replace the bottom rail instead of letting water sit against the frame.
- Latching and lock failures on retrofit double-hungs: ECO retrofit or insert double-hung units often drop out of square when the original opening wasn’t shimmed correctly. We re-shim the jamb, realign the sash, and replace the lock assembly so the window actually latches.
ECO Window Systems Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos caps lot coverage at 45% and design-reviews second-story additions, so window placement and glazing specs on a remodel get scrutinized at the planning counter. That’s a Los Altos-specific constraint. A homeowner replacing one failed ECO slider in a flatland Peninsula city can usually swap the unit and move on. In Los Altos, if the replacement changes the opening size or the glazing spec, the planning counter may want drawings, and the design review board may weigh in. Homes on the foothills edge, especially in the 94024 ZIP, face an additional layer: the wildland-urban interface requires fire-rated glazing that flatland cities never ask for.
On a 1962 ranch off Covington Road in the foothills edge, our crew found every original ECO aluminum slider dragging on its track and fogged at the seal—exactly the kind of ECO Window Systems repair in Mountain View and nearby areas we handle regularly. The owner hadn’t budgeted for a WUI glazing upgrade. We rebuilt the rollers and drainage channels on the salvageable units, matched OEM profile sash on the rest, and swapped the street-facing openings to fire-rated assemblies. The design-review drawings cleared without a variance. That’s what local knowledge buys you in Los Altos.
Does Replacing Original 1960s ECO Windows Trigger Los Altos Design Review?
Usually, no, if the replacement matches the original opening size and the home is not in a WUI zone. Design review kicks in when a second-story addition or expansion changes the exterior appearance, or when the planning counter flags new glazing as a fire-safety item. If your home is in the 94024 foothills edge, the answer changes: fire-rated glazing may be required, and the planner will likely ask for it up front. We’ve taken enough ECO Window Systems repair in Stanford and Los Altos window jobs through this process that we keep the paperwork moving instead of letting it stall.
What catches people off guard is the lot-coverage cap. A window job alone doesn’t add square footage, but a home addition that expands the footprint almost certainly hits the 45% cap. When we install ECO windows as part of a Los Altos General Contractor addition, we look at the whole project through that lens before we order a single unit.
ECO Window Systems Models & Products We Service in Los Altos
We service the ECO Window Systems product lines most common across Los Altos ranches:
- Series 5000 vinyl single-hung
- ECO aluminum slider and fixed picture windows
- ECO vinyl horizontal sliders
- ECO retrofit and insert double-hung units
For parts, we take a repair-first approach. We match OEM ECO sash, roller, and weatherstrip profiles where they’re still available, and we use quality aftermarket balances, screens, and glazing when OEM is discontinued. We do not force a full-replacement upsell. When frames are still true and only hardware or glass has failed, we repair. When vinyl is warped or aluminum is pitted through, we tell you straight that replacement is the better spend. We also carry common ECO profile stock for faster Los Altos turnaround on repairs.

FAQs – ECO Window Systems Construction in Los Altos
Yes, if the frame is still square and the sash is not warped. We replace the failed IGU and reseal the unit. If the aluminum track is pitted or the vinyl frame has racked out of square, a new IGU won’t seat properly, and replacement becomes the better spend. Call (844) 681-3590 and we’ll evaluate the units free of charge.
Yes, in most cases, if the home sits in the wildland-urban interface zone. The WUI rules apply to replacement glazing, not just new construction. We handle the fire-rated assembly specification and the city paperwork so the replacement clears the planning counter. Call (844) 681-3590 and we’ll check your specific property.
Usually not, if you’re matching the original opening sizes and the home isn’t in a WUI zone. Design review comes into play for additions, second-story work, or any change that alters the street-facing appearance. We’ll tell you up front whether your project needs drawings before we order materials.
The addition itself has to clear the 45% lot-coverage cap and design review, and if the property is in the foothills edge, the windows need fire-rated glazing. We spec the ECO units to meet both the city’s size rules and the WUI glazing standard early, then handle the submittal so the window package doesn’t hold up the permit. Call (844) 681-3590 to review your addition plans.
If the yellowing is cosmetic but the frame is still square, we can replace the weatherstrip and hardware and get the slider operating smoothly again. If the vinyl has warped at the sill, the sash won’t seal no matter what we do, and replacement is the honest answer. We’ll tell you which one you’re looking at, no upsell. Call (844) 681-3590 for a straight evaluation.
