ECO Window Systems Kitchen Remodeling: The Sherman Oaks Owner’s Guide
ECO Window Systems kitchen remodeling in Sherman Oaks typically runs $14,000-$45,000 installed, depending on scope, with written quotes delivered before any work begins. We stock and install ECO Window Systems-compatible windows and doors as part of kitchen remodels throughout the San Fernando Valley, including projects near the Galleria corridor and the residential streets off Ventura Boulevard. Most Sherman Oaks homeowners discover their ECO Window Systems units need attention during a kitchen renovation when they remove cabinets and find the existing windows don’t meet current Title 24 energy codes, or when they notice condensation between panes that wasn’t visible before the demo started.
Which ECO Window Systems Models This Applies To
ECO Window Systems manufactures vinyl and aluminum window and door lines common in Southern California tract homes built between 1995 and 2015, which describes much of Sherman Oaks’s housing stock. The ECO 5000 series vinyl single-hung and horizontal slider are the units we encounter most often in kitchen remodels here, followed by the ECO 8000 aluminum thermal break line used in some condos near the Ventura Boulevard corridor.
To identify your model, check the etched marking in the lower corner of the glass or the sticker on the frame edge. You’ll need the series number, the rough opening dimensions (not the sash size), and whether your wall is stucco, wood siding, or a combination. The ECO 5000 uses a 2-5/8″ frame depth that conflicts with some modern drywall returns, a gotcha we’ve handled on at least a dozen Sherman Oaks jobs. For ECO Window Systems, we typically recommend OEM sashes with upgraded low-E glass rather than full-frame aftermarket equivalents, because the ECO pocket sill design doesn’t always seal cleanly with third-party frames. We stock common ECO 5000 sash sizes on our truck; 8000 series aluminum frames we order to measured spec with a 10-day lead time.

Signs Your ECO Window Systems Kitchen Remodeling Is Failing

- Fog or moisture between double-pane glass. The ECO 5000’s insulated glass unit (IGU) seal has failed, which happens faster in Sherman Oaks’s heat-cycling climate than in milder regions. The desiccant inside the spacer bar saturates, and the visible haze means the thermal performance is already compromised.
- Sash won’t stay open or slams shut unexpectedly. The balance shoe or coil spring in the ECO single-hung has worn out, a common failure after 15-20 years of vertical travel. In kitchens, grease accumulation accelerates the wear.
- Air leaks around the frame, especially near the sill. The ECO pocket sill design can trap debris and standing water, degrading the weatherstrip and allowing conditioned air to escape. We find this consistently in older Sherman Oaks homes with overhangs that don’t shed rain adequately.
- Difficulty locking or visible frame distortion. Aluminum ECO 8000 frames can thermally expand enough to throw off the lock strike plate alignment, or the vinyl in 5000 series can sag if the reinforcement chamber was undersized for the sash weight.
- Exterior noise increase. When the IGU seal fails or the weatherstrip compresses permanently, the sound-dampening air gap becomes less effective. Homeowners on busy Sherman Oaks streets like Van Nuys Boulevard notice this first.

| Component | Sherman Oaks Price Range |
|---|---|
| Kitchen Remodel (full, including ECO Window Systems replacement) | $14,000-$45,000 |
| Window Replacement (per opening, ECO-compatible) | $450-$1,200 |
| Sliding Glass Door Replacement (ECO-compatible) | $1,800-$4,500 |
| Countertop Installation (Cambria, Silestone, or equivalent) | $2,000-$6,500 |
| Cabinet Installation (KraftMaid, Wellborn, or equivalent) | $4,000-$13,000 |
| Backsplash Installation | $800-$2,500 |
The range reflects three variables: whether we’re replacing sashes only or full frames, the glass package upgrade (standard low-E vs. argon-filled vs. laminated for sound), and the wall condition we find once cabinets come out. Stucco repair, header reinforcement, or dry rot remediation we quote separately with photos, under Clause 1 of the Haven Standard: the price is written before anyone starts. Every kitchen remodel includes a documented photo record of pre-existing conditions, the demo phase, and final installation, delivered as standard. Our 365-Day Done Right Promise covers the workmanship; manufacturer warranties on ECO-compatible glass and hardware run 10-20 years depending on the package selected.
DIY or Call Us?

There’s a clear line here. A homeowner can safely check the etched model number, measure the rough opening with a tape measure, and photograph the existing trim and siding condition. That’s useful information, and we’ll use it to speed your quote.
What goes wrong fast: ECO Window Systems units, especially the 5000 series with integrated nail fins, are designed for new construction or full-frame replacement, not insert-style retrofits. Removing a sash without understanding the balance system can release spring tension unexpectedly. The aluminum frames in the 8000 series conduct heat aggressively; improper flashing detail creates condensation paths that rot the stud bay. And in Sherman Oaks, any window replacement that alters the opening size triggers a permit with LADBS, plus Title 24 compliance documentation that most homeowners haven’t prepared before.
We don’t recommend DIY for ECO Window Systems replacement in a kitchen remodel context. The coordination with cabinet install, countertop templating, and backsplash sequencing matters too much. Call (213) 221-0788 to schedule your free estimate. We’ll measure twice, write it down, then build it.
FAQs
Expect 20-30 years for vinyl, 25-35 for aluminum thermal break, though the IGU seal often fails first in our heat-cycling climate. We’ve replaced ECO 5000 series units in Sherman Oaks that were 18 years old with fogged glass but mechanically sound frames. Call (213) 221-0788 for an exact quote on your specific units - estimates are free.
IGU seal failure can’t be repaired to factory spec; the glass unit must be replaced. However, if the frame and hardware are sound, we can often order a replacement sash with upgraded low-E glass that fits the existing ECO frame, cutting cost by 40-60% versus full-frame replacement. Call (213) 221-0788 and we’ll inspect to confirm.
Two to four days for a typical kitchen’s window openings, assuming standard sizes and no structural surprises. Custom-size ECO 8000 series aluminum frames add 10 days to the order lead time. We sequence window install before cabinets and countertops to protect the finish work. Call (213) 221-0788 to review your project timeline.
We stock common ECO 5000 series sash sizes and hardware on our truck for same-day replacement in Sherman Oaks. ECO 8000 series aluminum frames and custom glass packages we order to measured spec.
