ECO Window Systems Construction in Los Altos, CA | San Bruno Construction
We provide independent ECO Window Systems construction and replacement service across Los Altos, ZIPs 94022, 94023, and 94024. What makes our ECO work different here is simple: we understand how these windows actually behave on Los Altos’s ranch-era lots, where second-story additions, rear bump-outs, and design-review requirements shape every opening before a permit gets issued. Call (866) 472-1908 for a free estimate on replacement, impact installation, or window work tied into a larger addition.
San Bruno Construction is an independent contractor. We are not authorized, sponsored, or endorsed by ECO Window Systems. We work from hands-on familiarity with their frames, glazing, and hardware across Peninsula remodels, not from a manufacturer relationship.
Why Los Altos Residents Choose Us for ECO Window Systems Service
Los Altos homeowners deal with a specific kind of Los Altos Home Remodeling window work. The housing stock here leans heavily toward 1950s through 1970s ranch and Eichler-era single-story homes, many since expanded upward or outward. That means we regularly see ECO Window Systems units installed into original tract-era openings that were never reframed, or added as part of a second-story build where the glazing spec got locked in during design review.
Noel Carvalho, owner of San Bruno Construction, trained in construction technology at Skyline College and has run residential projects across San Mateo County for over two decades. He’s overseen enough Los Altos remodels, including ECO Window Systems repair in Stanford and nearby areas, to know what a fogged west-facing ECO slider looks like after fifteen Peninsula summers. We carry the replacement sashes, balances, glazing cartridges, and weather seals needed for faster Los Altos turnaround, and we tell owners plainly when a reglaze makes sense versus a full unit swap.

Common ECO Window Systems Construction Problems We Solve in Los Altos
- Fogged glazing and failed seals on south- and west-facing units. Los Altos summers are dry and long, and the afternoon sun on a west elevation punishes glazing seals. We replace failed assemblies with laminated glass and reseal the perimeter so condensation stays out of the air gap.
- Vinyl frame and sash warp that makes sashes drag or refuse to latch. Heat cycling over years softens and shifts vinyl. On 1960s-era Los Altos openings that were never reframed, we often find sashes that bind in the track. Sometimes a balance and weatherstripping replacement fixes it; sometimes the frame itself has moved past saving.
- Water intrusion at sill pans during atmospheric-river storms. Los Altos gets most of its rain in a few heavy winter storms. Where replacement windows were installed into original ranch wall framing without proper flashing, water finds its way in. We reflash and reseal sills ahead of the rainy season.
- Degraded balances and weatherstripping on sliders and hung units. Drafts and interior condensation on remodeled second-story additions are a frequent call. Worn balances let sashes drop; dead weatherstripping lets air move. We replace both with OEM or quality aftermarket parts.
- Slider patio doors that no longer glide or seal. ECO sliding doors take a beating when they serve as the primary rear access on a ranch lot. We rebuild tracks, swap rollers, and replace weather seals so the door actually closes tight.
ECO Window Systems Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos enforces tight lot-coverage and floor-area-ratio limits with strict setback rules. What that means for ECO Window Systems owners is unusually specific: many window packages in this town get finalized during design review and variance approvals, not on the job site. A homeowner planning a rear bump-out or second-story addition off a low-slung ranch in the 94022 ZIP near the village core will often need the window spec, glazing type, and opening sizes approved by the city before a permit is even issued. Swap a window size after approval and you’re back at the counter.
That’s a different rhythm than neighboring cities where you can make a field call and keep moving. In Los Altos, the window plan is part of the entitlement. We coordinate that work as your Los Altos General Contractor: spec the ECO units to match what design review approved, order the right glass package, and make sure the framing and flashing details match the approved plan. On a second-story addition off a 1960s ranch near the village core, we found the original ECO vinyl sliders bound and the west-facing units fogged between panes. We replaced the failed glazing with laminated assemblies, reflashed the sills ahead of the rainy season, swapped degraded balances and weatherstripping, then tied the new addition’s windows into the same frame family so the house read as one elevation. That’s the kind of job where knowing both the product and the city’s process matters.

We work on ECO Window Systems vinyl single-hung and double-hung replacement windows, sliding patio doors and vinyl slider windows, fixed and awning picture-window units for rear additions, and aluminum/vinyl retrofit frames sized for tract-era ranch openings. On any of these, we lean on genuine ECO replacement sashes, balances, glazing cartridges, and weather seals where they’re still available. When the OEM part is discontinued or the assembly itself is past saving, we use quality aftermarket glass and hardware and tell you exactly what we’re putting in and why.

AfterECO Window Systems Service Pricing in Los Altos
Window work in Los Altos varies widely because the scope does too. A simple replacement of a few ranch units lands at the lower end; a full impact-window package or window work tied to a second-story addition runs far higher. Here’s what we tell Los Altos homeowners to expect:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition (window work included) | $45,000 – $130,000 |
| Roof Repair (often tied to flashing work) | $400 – $1,800 |
What shifts the number: number of units, whether frames can be reused or need reframing, glass package, and whether the work happens inside an active design-review approval. We give written line-item estimates, and they’re free. Call (866) 472-1908 and we’ll walk your project with you.

FAQs – ECO Window Systems Construction in Los Altos
Yes. We match frame style, glazing profile, and color as closely as the current ECO lineup allows. When an exact match isn’t available because a line has been discontinued, we’ll show you the closest compatible option and explain the difference before ordering. Call (866) 472-1908 for a free estimate.
Not always. If the frame is sound and the rest of the unit is in good shape, we can often replace just the glazing assembly – the fogged cartridge comes out, a new sealed unit goes in. If both panes have failed or the frame has warped, replacement is the more honest spend. We’ll tell you which one applies to your window.
They can affect it significantly. If your window work is part of a second-story addition or rear bump-out, the city may require the window spec and opening sizes be locked in during design review before a permit is issued. Changing a size afterward means another round of approval. We handle that coordination, just as we do for ECO Window Systems repair in Los Altos Hills properties.
They can, if installed and flashed correctly. The two failure points we see most in Los Altos are west- and south-facing glazing seals breaking down from years of dry summer sun, and sill leaks during winter atmospheric-river storms where flashing was skipped or never detailed. Proper installation and periodic seal maintenance go a long way.
Often yes. Many Los Altos remodels touch a kitchen or bath that sits on an exterior wall, meaning windows get replaced or added as part of the same scope. We coordinate the window work under one contract instead of handing you off to a separate window crew. Call (866) 472-1908 for a combined estimate.
