ECO Window Systems Construction in Palo Alto, CA | Moreno Valley Builders
We’re Moreno Valley Builders, our General Contractor in Palo Alto, providing ECO Window Systems construction service across the city, including 94301, 94303, and 94304. We install, repair, and rebuild ECO vinyl windows, sliders, and fixed units in the housing stock that defines this city: 1920s Professorville bungalows, 1950s Eichler post-and-beam homes, and everything in between. What separates our Palo Alto work from a generic window swap is that we size and flash units to survive both the rainy-season storms and the city’s permit and design-review process. Call (877) 752-3154 for a free estimate.
Why Palo Alto Residents Choose Us for ECO Window Systems Service
We’ve spent years installing and servicing ECO Window Systems units across the Midpeninsula, so we know where their vinyl lines hold up and where they fail in Palo Alto’s specific mix of aging wood-frame bungalows, Eichler post-and-beam walls, and winter storm exposure. We’re an independent contractor, not authorized, endorsed, or warrantied by ECO Window Systems, which means our loyalty is to getting your openings square, flashed, and dry rather than to any single product line. Noel Trevino, our owner and general contractor, grew up in Sunnymead Ranch and has spent nearly three decades framing, flashing, and fixing homes across California. He’ll tell you the same thing on a Palo Alto job site that he tells Moreno Valley neighbors: if the details aren’t right on paper, they won’t be right in the wall. We bring that approach to every ECO Window Systems installation and repair in Palo Alto. Learn more about our broader work on our ECO Window Systems sales & service page.

Common ECO Window Systems Construction Problems We Solve in Palo Alto
- Fogged insulated glass on south- and west-facing units. Palo Alto’s dry summers mean intense UV cycling, then atmospheric river storms hit between October and April. That cycle stresses ECO insulated glass seals until they fail and fog. We rebuild the sash with new glass and seal when the frame is still square and dry.
- Water intrusion at the sill pan on flat-roof Eichler additions. South Palo Alto’s Eichlers have low-slope roofs that pond during winter storms. If the original flashing was lapped for a wall that has since been re-sided, water tracks into the rough opening. We cut out the failed pan, re-flash with positive slope, and reset the unit.
- Racked frames and binding sashes in older walls. Palo Alto’s 1920s and 1940s wood-frame homes have moved with decades of seasonal soil moisture. An ECO window in a racked opening binds, won’t seal, and eventually stops locking. We re-square the opening or sister framing as needed before reinstalling so the unit actually operates.
- Worn sweeps and weatherstripping on patio sliders. Wind-driven winter rain finds every gap in an ECO slider track. When the sweep is compressed or the weatherstripping is brittle, water sits in the track and wicks into the wall cavity. We replace OEM or equivalent seals and adjust the rollers so the panel closes tight.
- Fogged mullion-combination units on second-story additions. Palo Alto’s compatibility review often reshapes wall lines and window placement. When a mullion unit gets installed in a revised opening without re-flashing, the joints leak. We disassemble, re-flash each opening, and reset the combination as one plumb assembly.
ECO Window Systems Service in Palo Alto: What Local Conditions Mean for Your Equipment
Palo Alto’s neighborhood compatibility review and tree-protection ordinance for mature heritage oaks and redwoods can reshape a project’s wall lines and window placement before a permit is even pulled. That’s a pre-construction reality that rarely applies in neighboring Peninsula cities like Mountain View or Menlo Park. On Palo Alto jobs we often size and re-flash ECO units to a revised opening rather than the original drawing, because the city’s design review can move a window over by eighteen inches to protect a redwood’s root zone or keep a Professorville bungalow’s street-facing elevation compatible with its neighbors. We account for that at the estimate stage. If a heritage oak sits within the protected distance of a wall where a new ECO slider is going, we check the ordnance setback before we order the unit. That means fewer surprises when the permit set comes back marked up, and fewer re-cuts on site. For a full look at where we work, see our Palo Alto service area page.
On a 1950s Eichler in south Palo Alto near ECO Window Systems service in West Menlo Park, our crew opened a west-facing wall to replace fogged ECO sliding units and found the original low-slope roof had been ponding against the header, leaving the sill pan rusted and the rough opening out of square. We sistered the framing, rebuilt the pan and flashing with a positive slope, and set new ECO sliders shimmed to the corrected opening. Two storm seasons later the track still drains and the glass is clear. That’s the kind of condition Palo Alto’s housing stock throws at you, and it’s why we don’t quote a window swap without looking at the rough opening.
ECO Window Systems Models & Products We Service in Palo Alto
We install and service the full ECO Window Systems product range across Palo Alto: vinyl single-hung and double-hung replacement series, sliding glass door and patio slider units, fixed and picture window combinations for additions and ADUs, and casement and awning series used on rear elevations and second-story additions. For parts, we use OEM ECO sashes, glass, and hardware where the frame is sound and the unit is still in production. When OEM is discontinued or the lead time would leave an opening exposed into the rainy season, we source quality aftermarket glass and seal kits that match the original spec. Our honest stance: if the frame is plumb and the flashing is intact, a glass-and-seal rebuild usually makes sense. If the rough opening has racked or the sill pan is rotted, replacing the unit without fixing the wall just buys you the same failure in five years.

AfterECO Window Systems Service Pricing in Palo Alto
Window and construction pricing in Palo Alto reflects the cost of doing business in a city with strict permitting and high land values, plus the condition of the rough opening more often than the window itself. Here are the ranges we work within:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair (flat-roof Eichler flashing) | $400 – $1,800 |
| Full Kitchen Remodeling | $14,000 – $45,000 |
What drives the final number is whether the rough opening is square, whether the sill pan needs rebuilding, and whether the city’s permit review changes your wall lines before we cut anything. A free estimate from us includes a site walk, a check of the existing flashing and framing, and a written line-item quote. Call (877) 752-3154 to schedule yours.

FAQs – ECO Window Systems Construction in Palo Alto
Yes. Palo Alto treats window replacement as a building permit item when the opening size changes, when structural framing is involved, or when the home falls under neighborhood compatibility review. For a straight same-size replacement in an existing opening, the city may allow a simpler path, but we never skip the permit check. Call (877) 752-3154 and we’ll tell you what your specific bungalow triggers before we quote.
Because the water isn’t coming through the glass. It’s getting in at the sill pan, the track weep holes, or the flashing where the slider meets the wall. Dry summers hide the problem; winter atmospheric rivers expose it. We find and fix the actual entry point, which is usually not the slider panel itself.
Yes, in most cases. We work from the wall side, not the roof side. We cut the window out, rebuild the sill pan and flashing with positive slope, and set the new ECO unit into the corrected opening. We only touch the roof membrane if it has already failed at the header. Call (877) 752-3154 for an exact quote.
Then we check Palo Alto’s tree-protection ordinance setback before ordering anything. A heritage oak or redwood within the protected distance can change your window’s placement or even require an arborist report during design review. We plan for that up front so your permit set isn’t rejected on the first submittal.
We’re not authorized, endorsed, or warrantied by ECO Window Systems. We’re an independent contractor. Depending on the unit’s age and the nature of the failure, ECO’s own product warranty may still apply to the unit itself; labor and installation coverage is separate. We can help you understand what a given repair means for any remaining manufacturer warranty. Call (877) 752-3154 and we’ll walk you through it.
