ECO Window Systems Windows & Doors: The Sherman Oaks Owner’s Guide
We stock and install ECO Window Systems-compatible windows and doors across Sherman Oaks, with typical installed replacement costs running $4,500-$15,000 for standard window replacement and $8,000-$25,000 for impact-rated units. Most ECO Window Systems parts we carry on the truck, and we can measure, quote, and start work within a single visit when the opening is accessible. Most Sherman Oaks homeowners discover a problem when the sash won’t stay open on its own, they feel a draft along the frame in January, or condensation appears between the glass layers of a unit that was installed during the 2015-2019 building boom.
Which ECO Window Systems Models This Applies To
ECO Window Systems manufactures vinyl and aluminum window lines including the ECO 5000 Series, ECO 8000 Series, and the ECO Impact line rated for high-velocity hurricane zones. The model number is stamped on the spacer bar between the glass panes, visible when you open the sash and look at the top edge of the frame. You’ll also find a manufacturing date code; units produced before 2018 used a different balance shoe width (5/8-inch) than current production (3/4-inch), and the two are not interchangeable without modifying the jamb liner.
We source OEM ECO Window Systems parts where the factory still supports the series, and we stock quality aftermarket equivalents from Truth Hardware and Amesbury for discontinued lines. The aftermarket route saves roughly 15-20% on hardware costs and carries the same 10-year warranty we offer on OEM components. For ECO Impact units, we stick with factory-original glazing beads and reinforced locks; the pressure cycling those units see makes aftermarket tolerances risky.
Signs Your ECO Window Systems Windows & Doors Is Failing

- Sash drops or won’t stay open. The coil balance system has lost tension, usually from a broken spring or worn pivot bar. In Sherman Oaks, we see this most often on south-facing units where daily thermal expansion fatigues the metal faster.
- Visible moisture between glass panes. The insulating glass unit (IGU) seal has failed, allowing humid Valley air to enter the cavity. Once the desiccant saturates, the fogging becomes permanent and the thermal performance drops to roughly that of single-pane glass.
- Difficulty locking or unlocking. The multipoint lock mechanism has corroded or the keepers have shifted out of alignment. ECO’s earlier aluminum frames are particularly prone to this as the substrate flexes slightly with temperature swings from 45°F winter mornings to 105°F August afternoons.
- Air infiltration around the frame perimeter. The weatherstrip has compressed or the frame-to-wall sealant has cracked. On homes near the 405 freeway corridor, vibration from traffic accelerates this degradation compared to quieter interior streets.
- Cracked or warped vinyl frame. UV exposure has degraded the PVC compound, causing it to become brittle or bow inward. Dark-colored exterior frames absorb more solar heat and fail faster; we document this regularly on units above the second story with no eave protection.

| Service | Price Range in Sherman Oaks | What’s Included |
|---|---|---|
| Standard window replacement (per opening) | $4,500-$15,000 | Unit, installation, trim repair, disposal, 10-year workmanship warranty |
| Impact window replacement (per opening) | $8,000-$25,000 | Rated unit, structural reinforcement if needed, permit, inspection, documentation |
| IGU (glass-only) replacement | $300-$700 | Custom-measured sealed unit, installation, argon fill where specified |

What drives the range: the size of the opening, whether the existing frame is square and structurally sound, and whether we need to match interior trim or exterior stucco. Under Clause 1 of the Haven Standard, we deliver a written price before any work starts. No change proceeds without a signed change order. Our 365-Day Done Right Promise covers the installation; the glass itself carries the manufacturer’s warranty, which we register on your behalf.
DIY or Call Us?

There’s a safe middle ground here. A homeowner can check the model stamp, photograph the failed component, and verify that the sash moves freely in the frame without binding. What we don’t recommend: removing a fixed sash from an ECO Impact unit (the glazing beads are under compression and can release suddenly), or attempting to rewind a coil balance without the proper winding tool (the spring stores significant energy and can cause laceration).
We’ve also seen DIY IGU replacement attempts where the homeowner measured the daylight opening instead of the glass-to-glass dimension, resulting in a unit that rattles or leaks. Measure twice, write it down, then build it. If you’re uncertain on any dimension or the frame shows distortion, call (213) 221-0788 and we’ll measure it correctly the first time. Estimates are free, and we bring a documented photo record of what we find.
FAQs
Vinyl frames typically last 20-30 years with proper maintenance; IGUs often need replacement at 15-20 years as the edge seal degrades from thermal cycling. Call (213) 221-0788 for an assessment of your specific units - estimates are free.
No. Once an IGU seal fails, the vacuum or gas fill is lost and cannot be restored in the field. Replacement is the only remedy that restores thermal performance. Call (213) 221-0788 to schedule a measurement.
A single window opening takes 2-4 hours; a full-home replacement of 10-15 units is usually completed in 2-3 days. We pull permits when required and schedule inspections so you don’t have to. Call (213) 221-0788 for a written timeline with your estimate.
We carry common hardware - balances, locks, keepers, and weatherstrip profiles - for the ECO 5000 and 8000 series. Glass units and complete frames are ordered to measurement, with typical lead times of 2-3 weeks for standard sizes, 4-5 weeks for custom. Call (213) 221-0788 to confirm availability for your model.
