ECO Window Systems Construction in Mount Hermon, CA | San Bruno Construction
We provide independent ECO Window Systems construction, replacement, and repair across Mount Hermon, CA. The thing that sets our ECO work apart here is that we build for fog, redwood duff, and slope movement, not just for a spec sheet. If your vinyl sliders stick every winter or your double-hungs fog between the panes and never clear, that’s the mountain telling you something. Call us at (866) 472-1908, and we’ll tell you straight whether it’s a repair or a replacement.
Why Mount Hermon Residents Choose Us for ECO Window Systems Service
We’re an independent construction crew that has installed and serviced ECO Window Systems products across the Santa Cruz Mountains for years. That matters because we work for the homeowner, not the manufacturer. No authorization or warranty endorsement implied, just honest assessment of what’s failing and why.
Noel Carvalho, our owner, trained in construction technology at Skyline College, where he learned to read plans and understand load paths before a single tool comes out of the truck. He’s run residential projects across San Mateo County for over two decades, and he’ll be the first to tell you that a window that works in Sunnyvale can fail in Mount Hermon within three seasons if it’s flashed for the wrong conditions. We have ECO Window Systems sales & service depth that comes from working on these specific units in this specific climate, not from a manufacturer training video.
For Mount Hermon homeowners, that means we know which ECO window lines hold up on shaded, damp elevations and which ones fight you every winter. We source OEM ECO Window Systems glass, sash, and hardware where it’s still available, and we match with quality aftermarket seals and rollers where OEM has been discontinued. We’ll always be honest about whether a fogged IGU on a sound frame is a glass swap or a full replacement.

Common ECO Window Systems Construction Problems We Solve in Mount Hermon
These are the failures we see repeatedly in Mount Hermon, not the generic list a manufacturer puts in a brochure.
- Sticking sliders and drafty gaps from warped vinyl sashes. On dark, limited-sun elevations, fog keeps frames damp and heat cycling warps the tracks. A slider that slides in July and jams by December is telling you the sash has moved. We reset or replace the sashes and align the tracks so the window closes true.
- Water intrusion behind failed perimeter seals. Mount Hermon’s winter rain finds its way behind the nail fin when flashing was barely adequate to begin with. By the time you see the interior staining, the rough opening and adjacent framing are already wet. We pull the unit, repair any rot, and re-flash for the wet side of the house.
- Fogged or failed insulated glass units. Persistent moisture and mountain temperature swings kill IGU seals. You get haze between the panes that no amount of cleaning touches. On ECO units with a sound frame, this is often a glass swap, not a new window, which saves real money.
- Corroded or misaligned hardware and rollers in ECO sliding doors. Years of damp, debris-filled tracks plus slope-related racking of the opening wear out rollers and strip adjustment screws. We clean the tracks, replace the rollers with quality aftermarket parts where OEM is gone, and realign the panel.
- Failed flashing at the head and sill on picture and awning units. Fixed windows leak less than operable ones, but only if the flashing was done right. Under Mount Hermon’s canopy, water runs down the wall for weeks in winter. If the head flashing was undersized or the sill pan missing, the window leaks. We fix it properly.
ECO Window Systems Service in Mount Hermon: What Local Conditions Mean for Your Equipment
Mount Hermon’s redwood-canopy tree-protection rules and high fire-severity zone designations mean exterior window work here often triggers both defensible-space and tree-preservation review. In practice, replacement units sometimes must be specified to balance ember-resistant assemblies with canopy shading. That’s a trade-off that doesn’t come up in the open flats of Scotts Valley or Felton with ECO Window Systems service, and it changes which ECO units and which glazing packages make sense on a given elevation. A house that sits in full shade under old-growth redwoods near the Mount Hermon Conference Center has a completely different moisture profile than a hillside cabin that catches afternoon sun. We read the site first, then the spec sheet, because in Mount Hermon the two rarely line up without some thought.
One more thing that shapes our work here. On a 1970s pier-and-beam rustic second home near the Mount Hermon Conference Center, our crew found ECO slider tracks packed with redwood duff and frames racked from slope movement, so sliders jammed and fogged IGUs had lost their seal. We replaced the failed glass units, re-flashed and re-sealed the rough openings against the wet side, and reset the openings so the new sashes close true. The homeowner finally stopped fighting the doors every winter. Good construction doesn’t announce itself – it just works, year after year.
ECO Window Systems Models & Products We Service in Mount Hermon
We work on the full ECO Window Systems residential lineup, including vinyl single-hung and slider replacement windows, double-hung vinyl window series, sliding glass patio doors, and picture and awning window units. For Mount Hermon turnaround, we keep common rollers, seals, and balance hardware on hand, and we can source OEM glass and sash through our supplier network without a three-week wait.
When OEM parts are discontinued, we don’t just shrug and sell you a new window. We match aftermarket seals and rollers that actually fit the ECO extrusion, because a $14 roller replacement is almost always better than a $900 window. If the frame is sound and the glass failed, we swap the IGU. If the frame is racked, we’ll tell you that too, and we’ll give you a straight answer on replacement options.

AfterECO Window Systems Service Pricing in Mount Hermon
Window work in Mount Hermon costs what it costs because of the site, not because someone’s padding a line item. Here’s what we’re seeing for typical ECO-related jobs:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair | $400 – $1,800 |
| Roof Replacement | $8,000 – $20,000 |
What drives the cost on a Mount Hermon job? Access, for one. If we’re hauling ladders up a slope or working around a redwood that can’t be touched, that’s more labor. Rot in the rough opening adds framing time. Fire-zone documentation and tree-review paperwork add coordination. Our free estimate includes a written line-item quote, so you see exactly what you’re paying for before you sign. Call (866) 472-1908 to schedule yours.

FAQs – ECO Window Systems Construction in Mount Hermon
They hold up as well as any vinyl window when they’re installed correctly, which means proper flashing, correct drainage, and the right glazing for the elevation. The problem in Mount Hermon isn’t usually the window itself. It’s that the installation wasn’t done for a site that stays damp for weeks at a time. We fix that. Call (866) 472-1908 to have us look at your specific units.
Often, yes. If the frame is square and the sash is sound, a fogged IGU is a glass swap, not a new window. We’ll measure the exact IGU thickness and dimensions, order the replacement, and swap it in. When the frame is racked or the sash is warped beyond repair, we’ll tell you that before you spend money on glass. Call (866) 472-1908 for an exact assessment and quote.
Quite possibly. Because Mount Hermon sits within a high fire-severity zone and under a dense redwood canopy, replacement work often triggers defensible-space and tree-preservation review as part of the permit process. We plan for that from the start, which means fewer surprises and fewer delays once work begins.
Usually it’s the house. On pier-and-beam foundations on sloped Mount Hermon lots, the opening can rack slightly as the soil moisture changes. The door then binds, even if the rollers are fine. We’ll check both, because replacing hardware on a racked opening won’t fix the bind. Call (866) 472-1908 and we’ll tell you what’s actually going on.
Yes. We’re our General Contractor in Mount Hermon, which means we coordinate roofing, window replacement, flashing, and the adjacent trades under one contract and one schedule. In Mount Hermon, where window leaks often pair with roof edge and flashing failures, that’s the difference between fixing the symptom and fixing the house. Call (866) 472-1908 to talk through your project.
