ECO Window Systems Construction in Los Altos, CA | Silver Line Contractors
We provide independent ECO Window Systems service across Los Altos, from re-glazing a fogged 1960s slider to full window and addition packages. The one thing that makes our ECO Window Systems work here different is that we understand what Los Altos’ design review and heritage tree ordinances do to a glazing schedule before the first pane arrives on site. Silver Line Contractors is not authorized, sponsored, or endorsed by ECO Window Systems. We’re a Los Altos General Contractor and full-scope construction crew that has pulled, re-glazed, and re-sealed these aluminum and vinyl units for years. Call (833) 400-1314 for a straight answer on repair versus replacement.
Why Los Altos Residents Choose Us for ECO Window Systems Service
ECO Window Systems aluminum sliders and vinyl units have been common on Los Altos ranch homes and second-story additions for decades. That means most window contractors in the area have seen them. What they haven’t all done is taken them apart down to the frame, cleared the weep slots, re-set the rollers, and matched glass to the original unit without upsell pressure. That’s the work we do regularly. Noel Carvalho, owner and general contractor at Silver Line Contractors, started his construction career on ECO Window Systems repair in Stanford and other South Bay residential builds where mid-century window retrofits were a weekly reality. He studied construction technology at Gavilan College and spent his twenties and thirties working every phase of residential builds across Santa Clara County before starting Silver Line. We carry OEM-compatible rollers, sash hardware, and sealed units sized for the common ECO Window Systems profiles, so Los Altos service calls don’t stretch into a two-week parts wait. And we’re local enough to know the streets of 94022 and 94024 without a map.

Common ECO Window Systems Construction Problems We Solve in Los Altos
- Flat-spotted rollers and dragging sashes. Decades of single-story ranch use means those aluminum slider tracks pack with grit and run dry of lubricant. The rollers flat-spot, the interlock stops closing tight, and the sash drags. We pull the panel, clean the track, and replace the roller set with hardware matched to the unit.
- Fogged and failed dual-pane sealed units. South- and west-facing Los Altos walls take summer sun and winter rain cycling. The edge seal fails, the desiccant saturates, and the glass fogs. We order factory-correct replacement sealed units where the frame is sound, and tell you straight when the frame isn’t worth saving.
- Sealed-over weep and drainage slots. A stucco patch or a thick coat of paint during a remodel and the sills no longer drain. Winter rain ponds in the channel and wicks into the drywall below. Clearing those slots is part of nearly every ECO Window Systems service we do on older Los Altos homes.
- Degraded frame-to-rough-opening seals. The 1950s-to-70s stucco-and-sheathing walls common in Los Altos settle and shift. The original seal around the frame breaks down, letting wind-driven rain and foothill clay dust into the wall cavity. Re-sealing the frame to the rough opening stops the cycle.
- Out-of-square addition openings. Unpermitted additions from decades past sometimes have ECO sliders framed out of square. The window operates poorly from day one. We identify it, re-frame where needed, and set the unit square before re-sealing.
ECO Window Systems Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos runs nearly every window and exterior change through residential design review and its tree-preservation ordinance. That’s the single biggest difference between servicing an ECO Window Systems unit here and doing ECO Window Systems repair in Mountain View or Palo Alto. Plans must be drawn around protected heritage oaks and redwoods, and the City often requires tree-protection fencing before an excavator moves. So a straightforward glazing retrofit on a 1960s ranch in the 94022 ZIP can sit in review for weeks longer than an identical job two miles north. That means the window work itself has to be scheduled and sequenced around review timelines, arborist reports, and site protections. We build that reality into our plans from the first site visit. On a recent Los Altos job off the 94022 side of town, our tech found original ECO Window Systems aluminum sliders in a rear addition dragging on flat-spotted rollers and fogging on the west elevation. We pulled and re-glazed the failed sealed units with matching dual-pane glass, replaced the roller sets, cleared the painted-over weep slots and re-sealed the frames to the rough openings. And because the lot backed onto protected oaks, we kept the tree-protection fencing up until the last pane went in and the arborist signed off. That’s the pace and sequence Los Altos requires.
ECO Window Systems Models & Products We Service in Los Altos
We service the ECO Window Systems aluminum sliding windows common in mid-century Peninsula retrofits, including Series 600 and 700-style single-hung and slider profiles. We also work on vinyl single-hung and horizontal slider replacement windows, vinyl patio sliding doors, and fixed, picture, and awning units used in rear-yard and addition glazing packages. Our approach on parts is simple: factory-correct replacement sashes, sealed units, and rollers when the frame is sound, and a quality aftermarket sealed unit or roller set when the OEM part is discontinued or costs more than the window is worth. We keep common ECO Window Systems hardware stocked locally so most ECO Window Systems sales & service calls in Los Altos turn around quickly. If a frame is bent, rotten at the sill, or out of square after a remodel, we tell you straight that replacement, not another repair, is the better money.

FAQs – ECO Window Systems Construction in Los Altos
Yes, when the frame is sound. We order factory-correct replacement sealed units matched to the original profile, pull the sash, and re-glaze in place. If the roller tracks are shot or the sill is rotted, we’ll tell you replacement is the better money before anyone cuts glass. Call (833) 400-1314 and we’ll inspect the unit and quote both paths.
Very often they do. Exterior window changes on many Los Altos properties run through residential design review, and work near protected oaks or redwoods may require an arborist report and tree-protection fencing before we start. We handle that sequencing and tell you the expected review timeline on the first visit. Call (833) 400-1314 and we’ll map out what your specific site requires.
Two different causes working together. Fogging is a failed dual-pane sealed unit, usually on south or west walls where Los Altos sun and winter rain cycling breaks the edge seal. Sticking is flat-spotted rollers grinding in a grit-packed track. We fix both, and re-address the weep slots so the sill drains properly again.
Yes. Second-story additions change the wind and drainage load on the original openings, and we commonly re-glaze older ECO sliders during the addition or replace them with new vinyl units where the frame has shifted. We frame the openings square before setting any new window. Call (833) 400-1314 for an estimate that covers the glazing as part of the addition scope.
Window replacement typically runs $4,500 to $15,000 depending on unit count, frame condition, and glass package. Impact-rated installation runs higher, $8,000 to $25,000. Re-glazing individual sealed units can come in under a full replacement, but the only way to quote it accurately is to open the frame and check the rollers, tracks, and weep system. Estimates are free. Call (833) 400-1314 for an exact number.
