ECO Window Systems Construction in Woodland Hills, CA | Mason Remodeling Co Woodland Hills
We provide independent ECO Window Systems renovation, repair, and replacement across Woodland Hills, from the flats near Warner Center up into the canyon lots south of Ventura Boulevard, as your trusted General Contractor - Woodland Hills. What makes our ECO Window Systems work different here is that we plan every job around two local realities: hillside fire-code glazing rules and the way expansive soil slowly racks window frames out of square. Call (831) 290-6866 for a written estimate before any work starts.
We are not a manufacturer-authorized dealer. We’re an independent contractor with years of hands-on time spent servicing and replacing ECO Window Systems aluminum and vinyl lines in Woodland Hills, and we carry that independence into every recommendation we make. If a part should be genuine ECO, we say so. If an aftermarket insulated glass unit gets you a better result faster, we tell you that too. Same-day availability for diagnosis is common on our schedule.
Why Woodland Hills Residents Choose Us for ECO Window Systems Service

Isaac Pruett grew up in Los Angeles and trained at Los Angeles Trade-Technical College, then spent years working job sites across the Valley, including long stretches around Warner Center and the neighborhoods surrounding it in Woodland Hills. He’s pulled enough windows out of 1960s ranch homes to know what a failed thermal seal looks like after fifteen straight summers above 100°F, and he’s the one who sets the standard for how our crews handle your home.
We show up the way a builder should. Every technician is background-checked and identity-verified under the Threshold Standard, which means you get a name and a photo before we arrive, and a photo ID badge at the door when we do. Written pricing is standard on every ECO Window Systems job, never a favor. And our 365-Day Done Right Promise says plainly: if the work isn’t right within a year of completion, we make it right at no cost to you.
Our teams know the ECO Window Systems product families and the Woodland Hills homes they’re installed in. That combination matters more than most people expect.

Common ECO Window Systems Construction Problems We Solve in Woodland Hills
- Fogged ECO 4000 Series dual-pane glass. Thermal seal failure is the number one issue we see on aluminum single-hungs in Woodland Hills. Repeated 105°F summers expand and contract the seal until it lets go, trapping moisture between the panes. We replace the insulated glass unit and reseal the perimeter against the next heat cycle.
- Sticking or misaligned ECO 8000 Series sliders on hillside lots. Expansive soil moves. It moves subtly, but over decades it racks window frames out of square just enough that vinyl sliders start binding. We realign the sash, replace worn rollers, and check the frame for the kind of structural movement that needs more than a window repair.
- Failed weep hole drainage in ECO 2000 Series picture windows. Heavy winter rain against a fixed picture window finds any clogged weep hole and backs water up at the sill. We clear the drainage path, confirm the flashing is still doing its job, and replace any sill components that have started to rot or corrode.
- Bent or sagging casement hinges on ECO 6000 Series windows. Santa Ana wind gusts push hard against casement sashes year after year. Hinges bend, sashes sag, and the window stops sealing. We replace the hinge hardware and adjust the sash so it closes square and tight.
- Frame corrosion on windows over 20 years old. Aluminum frames on canyon lots pick up moisture and oxidize. When corrosion has compromised the frame itself, we’ll tell you straight: full replacement beats piecemeal repair.
ECO Window Systems Service in Woodland Hills: What Local Conditions Mean for Your Equipment

Woodland Hills sits inside a Very High Fire Hazard Severity Zone. That’s a county designation, not a real estate slogan. For homeowners on hillside lots, it means any new or replacement window has to meet ember-resistant glazing standards under Los Angeles County building code. Flatland cities don’t face that mandate. We’ve replaced fogged ECO 4000 Series picture windows on 1960s ranch homes on Dumetz Road where the original thermal seal had failed after repeated 105°F summers, part of our Bathroom Remodeling in Woodland Hills expertise. We swapped in a new dual-pane low-E insulated glass unit with stainless steel glazing bead to resist future expansion, then resealed the perimeter with elastomeric flashing to meet hillside water intrusion rules. That job required both window expertise and an understanding of what the hillside inspector would be looking for.
South of Ventura Boulevard, many of these homes were built on zero-lot-line setbacks with upside-down floor plans, living areas stacked above garages. Contractors working flat ground never see the access puzzles these lots create. We’re used to them. Material staging, ladder placement, pulling a 6-foot slider out of a hillside bedroom without damaging the stucco below: this is regular work for us in Woodland Hills.
ECO Window Systems Models & Products We Service in Woodland Hills
We work on all four core ECO Window Systems product families: the ECO 4000 Series Aluminum Single-Hung, the ECO 8000 Series Vinyl Sliding Window, the ECO 2000 Series Fixed Picture Window, and the ECO 6000 Series Casement Window. That covers most of what’s installed in Woodland Hills’s 1950s-through-1970s housing stock, plus the newer hillside custom builds.
When a warranty-critical component fails, like a balance or a lock, we use genuine ECO Window Systems parts. For insulated glass units, we specify high-quality aftermarket IGUs that meet or beat the original thermal performance, because they arrive faster and often at a better price. For units over 20 years old with frame corrosion, we recommend full replacement. That’s the honest call. For a broader look at our ECO Window Systems sales & service work, that page covers the full scope.

FAQs – ECO Window Systems Construction in Woodland Hills
Yes, if your home is on a hillside lot within the Very High Fire Hazard Severity Zone, replacement windows must meet ember-resistant glazing standards under Los Angeles County code. We handle the compliance side so your inspector passes on the first visit. Call (831) 290-6866 for an exact read on your property.
Expansive soil absorbs winter moisture and dries out in summer, which shifts your foundation and racks the window frame slightly out of square. Vinyl sliders are sensitive to that movement. We can realign the sash and replace worn rollers. If the frame movement is significant, we’ll tell you what’s actually happening under the window before we sell you anything.
We can match the finish color closely using OEM or paint-matched aluminum extrusions. On mid-century homes, an exact match sometimes requires custom finishing, which we arrange before the job starts so there are no surprises on the day of install.
Usually it’s a flashing or drainage problem, not the glass itself. Clogged weep holes or failed perimeter sealant let water pool at the sill. We diagnose the exact source and fix the drainage path, not just the visible symptom. Call (831) 290-6866 and we’ll schedule a look.
Sometimes. Zero-lot-line setbacks mean we can’t always set ladders on the neighbor’s side. We plan access from your side of the property, and when a steep hillside face makes ground access impossible, we bring the right equipment. That planning happens before we confirm your quote, so the price you get is the price you pay.
