ECO Window Systems Construction in Pomona, CA | Stallion Contractors
We’re an independent construction crew that installs and services ECO Window Systems products across Pomona, CA, and provides ECO Window Systems service in Montclair. The thing that separates our ECO work here from a generic window contractor is simple: we’ve spent years pulling failed units out of mid-century Pomona homes and know exactly how this city’s sun, Santa Ana winds, and older rough openings beat on these windows. Call (855) 600-3192 for a free estimate on any ECO Window Systems repair or replacement.

Why Pomona Residents Choose Us for ECO Window Systems Service
We know ECO Window Systems products the way a mechanic knows a specific engine family. We’ve handled the ECO Series 1000 through 4000 in enough Pomona homes to tell you which failures show up on south-facing bedroom windows versus which ones come from bad flashing on a 1950s addition in 91766. Ruben Montoya grew up around Colton and the Inland Empire, and he built this company around a principle his father, a finish carpenter, drilled into him: the last ten percent of a job is what separates honest work from a callback.
We’re independent of the manufacturer. No authorization agreement, no corporate script. That independence means we make repair-versus-replace calls based on the condition of your windows and your budget, not a sales quota. When OEM parts are available, we source them. When a discontinued latch or balance leaves us no OEM path, we’ll tell you straight and fit an aftermarket component that meets or exceeds the original spec. Our ECO Window Systems sales & service work across the region has taught us one thing: Pomona homeowners want a straight answer, not a brochure.

Common ECO Window Systems Construction Problems We Solve in Pomona
- Warped and cracked vinyl frames on ECO Series 1000 units. Pomona’s summer heat is relentless, and south- and west-facing windows take the worst of it. We regularly replace frames that have bowed enough to let air and dust through. Santa Ana wind events push grit into the gaps and make the damage worse over time.
- Glass seal failure and fogged panes. The Inland Valley’s hot days and cool nights put thermal stress on insulated glass units year after year. Older ECO units in Pomona routinely develop failed seals by the ten-to-fifteen-year mark. Once the argon’s gone and condensation starts, the pane will never perform like it should.
- Faulty locks and crank mechanisms on casement and awning models. Dry, dusty seasons blow fine grit into hardware tracks across the 91767 and 91768 ZIP codes. We see casement cranks that bind, strip, or snap because dust worked its way into the gear teeth. A hardware swap is often all it takes.
- Water intrusion from improper flashing on older Pomona homes. Mid-century rough openings are rarely square and rarely standard. If a previous installer fudged the flashing detail to make a stock unit fit, the first real rainy season exposes it. We rework those openings the right way.
- Non-standard rough openings that make replacements a custom job. Original aluminum-framed windows in Pomona tract homes don’t match modern standard sizes. You can’t just order a stock ECO unit and expect it to seat correctly. We measure, order custom, and flash accordingly.
ECO Window Systems Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s something a manufacturer page won’t tell you. Pomona’s mid-century core, especially the 91766 and 91767 ZIP codes, is full of houses built in the 1940s through the 1970s with original aluminum-framed windows. Those rough openings were sized for a different era. When an ECO Window Systems replacement goes into a home near Lincoln Park or off Garey Avenue, it’s almost never a drop-in job. The opening might be a half-inch off in one corner. The header might have settled. The exterior stucco line might not be true. That means custom-sized ECO units, careful flashing, and a crew that knows how to make the trim look like it was always there. A crew that only handled ECO Window Systems repair in Claremont won’t recognize what’s waiting in a 1955 Pomona ranch. We learned it here. On a recent job in the 91767 area near Lincoln Park, we replaced a set of failed ECO Series 2000 single-hung windows in a 1950s ranch home. The originals had fogged glass and cracked vinyl frames from decades of sun. We installed ECO Series 3000 units with Low-E glass and reinforced frames, custom-ordered to the non-standard openings, and finished with proper flashing and trim to keep water out. That’s the difference between a window swap and a Pomona window swap.
ECO Window Systems Models & Products We Service in Pomona
We service the full ECO Window Systems lineup: the ECO Series 1000, Series 2000, Series 3000, and Series 4000. The Series 1000 is an entry-level vinyl line that shows up in a lot of Pomona’s rental and starter homes. The Series 2000 and 3000 are what we see most often in owner-occupied mid-century houses, where someone upgraded in the 1990s or 2000s. The Series 4000 is ECO’s higher-end line with stronger frames and better glass packages. When you call us, we’ll identify your model, assess the frame, glass, and hardware as one system rather than a collection of parts, and give you an honest repair-or-replace recommendation. OEM parts come first when they’re available. If ECO has discontinued a hardware set, we carry proven aftermarket alternatives locally so you aren’t waiting on a backorder.

AfterECO Window Systems Service Pricing in Pomona
Window work in Pomona varies because the housing stock varies. A simple hardware repair on one window is a completely different job from replacing eight openings in a 1960s ranch. Here’s what our pricing looks like for the ECO Window Systems work we handle most often:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Replacement & Installation | $8,000 – $20,000 |
Your final number depends on how many windows, what ECO series you select, whether custom sizing is required (it usually is in Pomona’s older homes), and whether we’re reworking any flashing or trim. A free estimate from us means we come out, measure, inspect the openings, and give you a written line-item quote. No vague ballpark, no change-order games later. Call (855) 600-3192 to schedule yours.

FAQs – ECO Window Systems Construction in Pomona
Do ECO Window Systems windows meet Pomona’s wildfire-resistant construction requirements for homes in the foothill areas?
ECO Window Systems windows can meet Pomona’s Chapter 7A-style fire-interface requirements when specified with the correct glass and frame packages, especially on north and northwest foothill-edge properties where defensible-space and ember-resistance standards apply. If your home sits in that wildland-urban interface zone, we’ll walk you through what the city’s building department will ask for and spec the right ECO units to pass inspection. Call (855) 600-3192 and we’ll review your specific property.

How do I know if my ECO Window Systems windows need repair or full replacement?
Fogged glass, visible vinyl warping, or a frame that lets daylight through the seal are strong signs replacement makes more sense than repair. A sticky lock or worn crank on an otherwise sound window is usually a straightforward hardware fix. We’ll tell you which one you’re looking at and show you why, rather than pushing the more expensive option.
Can you install ECO Window Systems windows in my older Pomona home without changing the exterior trim?
In most cases, yes. We cut custom-sized ECO units to fit the existing rough openings and re-install the original or matching trim so the exterior character of your mid-century home stays intact. The exceptions are when the original flashing or surrounding stucco has deteriorated enough that patching in place would create a future leak point.
What type of ECO Window Systems window is best for Pomona’s hot summers and occasional Santa Ana winds?
For Pomona’s climate, we recommend ECO Series 3000 or 4000 units with Low-E glass and reinforced frames on south- and west-facing exposures. The upgraded glass coating cuts solar heat gain during summer, and the stronger frames hold up better when Santa Ana winds push against the window. Series 1000 units simply don’t have the frame rigidity for full western exposure in this heat.
Do you provide warranties on ECO Window Systems installations?
Yes, our installation work carries a workmanship warranty, and the ECO Window Systems products themselves are covered by the manufacturer’s warranty. We don’t disclaim away installation defects. If a flashing detail fails or a window settles out of square because of how we set it, we come back and make it right. Call (855) 600-3192 and we’ll go over the warranty terms in plain language before any work starts.
