ECO Window Systems Construction in Irvine, CA | Rowan Construction Group
We provide independent ECO Window Systems service across Irvine, from single-sash hinge replacements to full-home window retrofits. The one thing that makes our ECO work here different: we know Irvine’s HOA and City of Irvine dual-approval process well enough to keep your project moving the first time. Call (470) 298-9650 for a free estimate, and we’ll walk the site before anyone touches a frame.
Why Irvine Residents Choose Us for ECO Window Systems Service
We’ve torn down and reinstalled ECO Window Systems frames on enough Irvine tract homes to know which of their series – from the base 2000 to the 3000 and 5000 – survive a coastal-influenced microclimate and which develop chronic sash sag after a few years of daily use. That’s not manufacturer training. It’s field time.
We’re an independent ECO Window Systems sales & service provider, not manufacturer-affiliated or authorized. That independence matters. We’re not pushed to sell a whole new window when a hinge will do. We stock OEM-equivalent aftermarket parts – sash hinges, locking handles, weep covers, glazing beads – and we replace the failed component, not the frame, unless the frame is warped or the glass edge seal is compromised beyond re-glazing.
Grant Rowan founded this company in 2007 after training in construction technology at Los Angeles Trade-Technical College, where coursework covered framing, concrete, and project estimating before he ever swung a hammer on a paying job. That’s the discipline behind every quote we write: the number goes on paper before the work starts, and it doesn’t change without a signed change order.
Common ECO Window Systems Construction Problems We Solve in Irvine

- Sash sag on ECO 2000 Series windows. The factory hinges on the 2000 Series are undersized for daily use. After two or three Irvine summers, the sash drops a quarter-inch and scrapes the frame. We replace the hinges with heavier-gauge aftermarket versions and reset the weatherstrip. That’s the fix, not a new window.
- Weep system failure on ECO 3000 Series fixed and sliding units. Irvine gets roughly 12 to 13 inches of rain a year, but when it comes, it’s often a short, hard downpour that overwhelms clogged weep channels. Water pools inside the frame track, then finds its way under the sill. We clear the channels, replace the weep covers, and check the sill slope.
- Thermal seal failure on ECO 5000 Series double-pane glazing. South and west exposures in Irvine take direct sun for hours a day. The edge seal breaks down, and you get condensation between the panes that cannot be wiped away. We replace the insulated glass unit, not the whole window.
- Hardware latch misalignment on ECO 8000 Impact Series windows. These are common in Irvine’s WUI zones and newer Great Park Neighborhoods builds. HOA-mandated stucco work shifts the frame before final set. The latch no longer aligns, and the window won’t lock. We realign the frame, reset the hardware, and document the fix.
- Warped frames from stucco intrusion. Irvine’s post-1970 tract construction means stucco against window frames. When the stucco expands and contracts through temperature cycles, it can press against the frame and bow it. We assess whether the frame needs replacement or just relief work.

AfterECO Window Systems Service in Irvine: What Local Conditions Mean for Your Equipment
Here’s the detail that separates Irvine from every neighboring city. In Portola Springs and Orchard Hills, which sit inside the Wildland-Urban Interface zone, any ECO Window Systems replacement on an exterior wall requires the new units to carry a California Chapter 7A ember-resistance rating and dual-pane tempered glass – even when the existing wood window was grandfathered under older HOA guidelines. That requirement changes both the product you can buy and the price you’ll pay, because 7A-rated assemblies cost more than standard units. Contractors from Anaheim or Eco Window Systems repair in Santa Ana routinely quote the work without accounting for it, then hit the homeowner with a change order when the city’s inspector flags the spec. We write 7A compliance into the original flat price, and we don’t start a WUI-zone job without confirming the requirement with the City of Irvine plan checker.
ECO Window Systems Models & Products We Service in Irvine

We service all four primary ECO Window Systems series: the ECO 2000 Series, ECO 3000 Series, ECO 5000 Series, and ECO 8000 Impact Series. Most of what we do is component-level repair – hinges, latches, weep covers, glazing beads – using OEM-equivalent aftermarket parts. The reason is simple: ECO frames are generally well-built. What fails is the hardware. Replacing a hinge for $240 to $500 instead of a whole window for $4,500 to $15,000 is the responsible call, and it’s the one we make every time unless the frame itself is compromised.
For full replacements, we source the same series windows rather than swapping in a competitor’s product that would look out of place in an Irvine HOA-governed village where trim colors and frame profiles are reviewed line by line, just as with our Driveway & Pavers in Irvine.

FAQs - ECO Window Systems Construction in Irvine
Yes. In Irvine, HOA architectural review is a separate legal requirement from the city building permit, and the city’s inspectors will not sign off on final occupancy if HOA approval was never obtained. If you’re changing the trim color, frame material, or profile, you’ll need ARC sign-off first. In Woodbridge or Northwood, skipping that step can get you a stop-work order even with a valid permit in hand. Call (470) 298-9650 and we’ll walk you through the paperwork before you buy a single window.
Almost always a hinge problem. The ECO 2000 Series ships with undersized hinges that wear out under daily use. The sash drops a quarter-inch and scrapes the frame. We confirm by pulling the glazing beads and checking whether the hinge mortises have wallowed out. If the frame itself is warped, that’s a different conversation, but it’s rare. The hinge fix runs $240 to $500 per window. Call (470) 298-9650 and we’ll inspect it before you decide.
Yes, but only with specific ratings. Any replacement window on an exterior wall in Portola Springs, Orchard Hills, or other WUI-adjacent Irvine villages must carry a California Chapter 7A ember-resistance rating and dual-pane tempered glass. This applies even if your old window was grandfathered under older HOA guidelines. We specify 7A-compliant ECO 8000 Series units on WUI jobs, and the price reflects the rating. Call (470) 298-9650 for a written quote.
The edge seal on the insulated glass unit has failed. That’s condensation inside the sealed airspace, not on the room-side surface. You cannot wipe it away. It means the unit has lost its insulating gas and the glass will eventually fog permanently. We replace the lite for $300 to $900 per unit, depending on size and glass type. Call (470) 298-9650 and we’ll confirm the seal failure in person.
It depends on the scope. A like-for-like sash or hinge repair does not require a permit. A full window replacement – pulling the frame and re-setting it – does, because Irvine’s building code treats it as an exterior alteration. And if you’re in an HOA-governed village, you’ll need architectural review as well. We pull the permit and handle the HOA submission as part of the written scope. Call (470) 298-9650 and we’ll tell you exactly what your project requires before you spend a dollar.
