ECO Window Systems Construction in West Hills, CA | Mason Remodeling Co Thousand Oaks
We provide independent ECO Window Systems construction service across West Hills, including window replacement, impact window installation, and roof repair tied to window openings, as part of our General Contractor - West Hills services. What makes our work here different is simple: we’ve spent years correcting ECO window failures on hillside homes where expansive soil movement has knocked rough openings out of square. If you own a West Hills home with ECO windows that fog, stick, or leak, call (805) 309-3386 for a free estimate. We know these windows and we know this terrain.
Why West Hills Residents Choose Us for ECO Window Systems Service
Our crews have performed hundreds of ECO Window Systems window and door installations, repairs, and retrofits across West Hills hillside homes. That matters because ECO windows don’t fail the same way here as they do in Woodland Hills or Canoga Park. The soil moves, the sun hits harder on south and west exposures, and winter rain drives against elevated lots. We’ve seen every failure pattern and we stock the parts to fix them.
Isaac Pruett, our owner, grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College before putting that foundation to work on real job sites across the region. He built our reputation on a simple standard: tell you what needs doing, what it costs, and how long it takes, then do exactly that. That’s not a slogan. It’s how we’ve run every ECO Window Systems job in West Hills.
We’re an independent ECO Window Systems service provider, not manufacturer-affiliated or authorized. That independence means we recommend what’s actually right for your home, not what a corporate program tells us to push. Call (805) 309-3386 and a live person answers, 24 hours a day, seven days a week.

Common ECO Window Systems Construction Problems We Solve in West Hills
Here’s what we see most often on West Hills homes, and why each failure happens the way it does here.
- Fogging between panes in ECO 2000 Series double-glazed units. The intense summer heat followed by cooler nights causes constant thermal cycling. Over time, the edge seals on ECO 2000 Series units break down, moisture gets trapped between the glass, and the window turns cloudy. The frames often stay structurally sound, which means a sash replacement usually solves it.
- Warped or stuck sashes in ECO 3000 Series vinyl frames. On southern and western exposures where afternoon sun peaks over the Santa Susanas, vinyl frames absorb a lot of heat. We regularly see ECO 3000 Series sashes that have warped enough to bind in their tracks. Sometimes we can re-square the sash. Other times the frame needs replacement and re-shimming.
- Failed locking mechanisms in ECO 4000 Series casement windows. Hillside pads in West Hills settle unevenly over decades. That uneven settling transfers torque to window frames. ECO 4000 Series casement locks take the brunt of it. When a lock fails, we replace it with new hardware and check whether the frame has shifted enough to need additional shimming.
- Leaking at frame-to-wall junctions in ECO 7000 Series fixed picture windows. Winter rain on elevated lots hits windows at an angle. ECO 7000 Series picture windows that weren’t properly flashed on the original install tend to leak at the top and side junctions. We remove the exterior trim, install proper flashing, and reseal the frame before re-trimming.
- Deteriorating weatherstripping from hard water and sun exposure. West Hills gets hard water. Combined with UV exposure, weatherstripping on ECO windows deteriorates faster than it would in coastal microclimates. We replace weatherstripping with high-quality aftermarket materials that meet or exceed the original fit when ECO OEM strips are out of production.
ECO Window Systems Service in West Hills: What Local Conditions Mean for Your Equipment
West Hills’ 1960s to 1980s custom hillside homes often have original window rough openings that are up to a half inch out of square due to expansive soil movement. That’s the defining condition of this area, and it changes the entire approach to window work. On flat lots in Woodland Hills or Canoga Park, a replacement window often drops into a square opening with minimal shimming. On a hillside home south of Victory Boulevard, the opening has likely shifted. That means more shimming, more custom flashing, and more care with the frame-to-wall seal. If a contractor treats a West Hills hillside window like a valley window, you get leaks within the first winter. We don’t treat them the same, because they aren’t. We measure every opening for square before ordering or cutting anything, and we build the installation plan around what the house has actually done over the past 50 years. That’s not standard practice. It’s the only practice that works here.
ECO Window Systems Models & Products We Service in West Hills
We service ECO 2000 Series, ECO 3000 Series, ECO 4000 Series, and ECO 7000 Series windows and doors. For current production models, we prefer genuine ECO Window Systems replacement sashes and hardware when available. For out-of-production models, we source high-quality aftermarket seals, balance rods, and weatherstripping that meet or exceed original fit. We repair rather than replace when the frame and glass are fundamentally sound, but recommend full-unit replacement on heavily fogged or structurally compromised windows where repair cost exceeds 60% of new. Our techs keep common ECO hardware and seal profiles stocked locally so most West Hills service calls don’t wait on parts.

FAQs – ECO Window Systems Construction in West Hills
Yes, in most cases we can. We source replacement sashes and hardware that match the bronze aluminum profile common on 1970s West Hills homes, and when exact-match OEM parts are no longer produced we use aftermarket components that match the visual profile closely. The real challenge on these homes is the rough opening, not the frame color. Bring us a photo of the existing window and we’ll tell you what’s possible. Call (805) 309-3386 and we’ll talk it through.
Yes, impact-rated ECO Window Systems windows are engineered for high wind loads, including the gusts that hit ridge lots above Victory Boulevard. What matters is the installation. A properly installed impact window with correct anchoring and flashing will handle West Hills wind. A poorly anchored one will fail at the frame no matter how strong the glass is. We anchor every impact window to the home’s structural framing and verify the opening is square before the unit goes in. Call (805) 309-3386 for a site assessment.
No, in most fogged-glass cases the frame doesn’t need replacement. We can replace the sash, which means new glass and seals while keeping your existing frame in place. That’s usually the smarter fix on 1980s ECO windows where the aluminum or vinyl frame is still square and structurally sound. If the frame itself has warped or the fogging is extensive across many panes, we’ll tell you straight whether replacement makes more sense. Call (805) 309-3386 for an inspection and we’ll give you both options with written pricing.
Hard water leaves mineral deposits in the weatherstripping tracks, which accelerates wear and makes sashes harder to operate. Intense sun, especially on south and west exposures, bakes and cracks vinyl and rubber stripping. We see weatherstripping on West Hills ECO windows fail several years sooner than on the coast. The fix is straightforward: we replace the stripping with UV-resistant materials and clean the tracks thoroughly before installing. Call (805) 309-3386 and we’ll include weatherstripping replacement in your estimate if it’s needed.
Yes, every large picture window on an older West Hills hillside home gets a structural assessment before we touch anything. We check the header, the king and jack studs, the condition of the sill plate, and whether the wall has shifted with soil movement. Large glazing on a hillside wall carries more load than most people realize, and a 1970s opening may not be up to today’s code. We’ll tell you what’s sound, what needs reinforcing, and what it costs. Call (805) 309-3386 to schedule that assessment.

One of our techs replaced a pair of ECO 3000 Series horizontal sliders on a 1970s hillside home off Kittridge Street, where the south-facing sashes had warped from afternoon heat and jammed in their tracks. We re-squared the openings with custom wood bucks, installed new ECO 3000 sliders with stainless steel corner keys, and added a deeper exterior drip cap to keep winter rain from driving into the frame. The homeowners now operate the windows with one hand and saw zero water intrusion during last January’s storms. Tell me what you need done. We’ll tell you what it costs and how long it takes, then we’ll do exactly that. Call (805) 309-3386 for your free estimate.
