ECO Window Systems Construction in Mountain View, CA | Rowan Construction Group Mountain View
We provide independent ECO Window Systems installation and repair across Mountain View, from Rex Manor ranch homes to new construction near North Bayshore. The one thing that sets our work apart here: we detail every opening for the bay’s persistent marine moisture and, where needed, for the differential settlement that Santa Clara County’s liquefaction maps flag in the northern former baylands. Call (669) 215-4852 to schedule your free estimate.
Why Mountain View Residents Choose Us for ECO Window Systems Service
We’ve been working on ECO Window Systems products in Mountain View for years. Vinyl single-hungs in 1960s slab ranches off Castro Street. Sliding patio doors in Cuesta Park additions. Casement units in remodels near downtown. We know how the fog rolls in and sits, and what it does to seals and hardware over a decade.
Grant Rowan grew up in Beverly Hills, learned the trade at Los Angeles Trade-Technical College on framing, concrete, and finish work, then spent two decades building before bringing that discipline to Mountain View. He and our crew have worked steadily here, including projects near Castro Street and the surrounding downtown blocks. We show up on time, keep a clean site, and write scopes that don’t leave room for invoice surprises. Grant still does his own home repairs by hand. “Keeps me honest about how long things actually take,” he’ll say.
We’re not authorized by ECO Window Systems. We’re independent. That means we source OEM sashes, glazing, and hardware when the unit justifies it, and we use quality aftermarket balances, weatherstripping, and sealants when the original part is discontinued or the repair math doesn’t work. Under Clause 1 of the Haven Standard, you get a written price before anyone picks up a tool. Every time.
Common ECO Window Systems Construction Problems We Solve in Mountain View

- Condensation and seal failure between insulated glass panes. ECO single-hung units in west-facing Rex Manor homes take the brunt of bay fog and marine moisture. The seal breaks, the glass clouds, and the thermal performance drops. We see this more in Mountain View than in inland Santa Clara County cities where the fog burns off faster.
- Vinyl frame warping and sash binding. ECO sliders and double-hungs on Mountain View’s 1950s-1970s ranches cycle through thermal stress: foggy mornings, warm inland afternoons, repeat for twenty years. The vinyl distorts. Windows stick. Latches won’t catch. We measure the opening, assess the frame, and tell you whether a new sash or full replacement makes sense.
- Water infiltration at sill and jamb flashing. Original ECO installations in Mountain View’s slab-on-grade ranches often lacked proper sill pans. Bay moisture finds the gap, stains drywall, and rots framing behind the unit. We pull the window, repair what we find, and reinstall with pan flashing and low-expansion foam.
- Fastener and hinge corrosion on awning and casement hardware. ECO hardware in bay-edge Mountain View neighborhoods corrodes faster than identical hardware in Sunnyvale or Los Altos. The marine air is the difference. We stock stainless and coated replacements for faster turnaround.
- Opening re-detailing for differential settlement in North Bayshore. Santa Clara County’s liquefaction hazard maps classify Mountain View’s northern former baylands as high-risk. Window openings in Shoreline-area remodels need framing and flashing details that account for potential soil movement. Out-of-area builders miss this. We don’t.

AfterECO Window Systems Service in Mountain View: What Local Conditions Mean for Your Equipment
Mountain View sits at the epicenter of two simultaneous construction pressures unique in the Bay Area. Massive commercial campus expansion in the North Bayshore district, north of Highway 101, where former bay marshland and fill soils create acute liquefaction and differential-settlement risk. And a residential infill and ADU pipeline among the most active in Santa Clara County, fueled by housing demand from Google and other major employers within walking distance of neighborhoods like Rex Manor and Cuesta Park.
For ECO Window Systems owners, this means something specific. Because Mountain View’s northern former-baylands areas are mapped as high-liquefaction-hazard zones by Santa Clara County, window openings in North Bayshore and Shoreline-area remodels often have to be re-detailed for differential settlement. The framing, the flashing, the way the unit sits in the wall - all of it gets scrutinized by city and county inspectors in ways that don’t come up in Sunnyvale jobs two miles south. We’ve had out-of-area contractors call us mid-permit because they didn’t budget for a geotechnical report or engineered foundation tie-in that the window installation triggered. We build that into the scope from the start. Measure twice, write it down, then build it that way.

We work on the full ECO Window Systems residential line: vinyl single-hung and double-hung replacement windows; sliding patio doors; awning and casement series; picture and fixed-frame units. For ECO Window Systems sales & service, we stock common sashes, balances, and hardware for faster Mountain View turnaround. OEM when it makes sense, aftermarket when the original is discontinued or the cost doesn’t pencil out. If your unit has failed seals plus warped vinyl, we’ll tell you straight: replacement usually costs less over ten years than chasing repairs.

FAQs - ECO Window Systems Construction in Mountain View
We service them. We’re an independent construction company, not manufacturer-affiliated. We’ve replaced and repaired ECO units in dozens of Mountain View’s 1950s-1970s ranch homes, including several in Rex Manor. Call (669) 215-4852 to schedule a free estimate.
Mountain View’s bay-edge position means more persistent marine moisture and fog, especially in west-facing homes. That accelerates seal degradation on insulated glass units. Sunnyvale sits slightly inland; the fog burns off faster, and the seals last longer. If the glass is clouded, the seal has failed and the sash needs replacement. Call (669) 215-4852 for an exact quote.
It can. Santa Clara County maps the northern former baylands as high-liquefaction-hazard, and the city may require geotechnical reports or engineered foundation systems for additions or significant remodels. Window openings in these areas need detailing for potential differential settlement. We build this into our scope and pricing from the start, not as a surprise change order.
Depends on age and extent. A warped sash on a newer unit often just needs a new sash and balance. On a 20-year-old unit with multiple failed seals and frame distortion, replacement usually costs less over ten years. We assess both paths and give you the numbers. Call (669) 215-4852 for a free second opinion on any written estimate.
Yes. Window replacement is a standard component of our kitchen and bathroom remodels in Mountain View. We coordinate the opening detail with the cabinet and countertop layout so nothing conflicts. The written scope covers all trades, not just the window.
