ECO Window Systems Construction in Fontana, CA | Elmstead Remodeling
We’re an independent remodeling contractor that installs and services ECO Window Systems windows across Fontana, and the work here is shaped by two things most brand pages never mention: expansive clay soils that move post-tension slabs, and summer heat that regularly pushes past 108°F. Those conditions are why a straightforward window replacement on an east-side tract home often needs a structural engineer’s eyes before we order units. Call (949) 850-9896 and we’ll walk you through what your home actually needs.
Our team has worked on ECO Window Systems vinyl sliders, single-hungs, and aluminum patio doors in Fontana for over a decade, from the flat grid near the 10 and 15 freeways up to the foothill lots along Baseline. We diagnose and repair these products daily. We are not authorized by the manufacturer, we don’t claim warranty endorsement, and we don’t pretend otherwise.
Why Fontana Residents Choose Us for ECO Window Systems Service

Graham Stein, our owner, learned framing and finish work at Los Angeles Trade-Technical College before spending close to two decades on homes across Southern California. What he brings to every Fontana job is sequencing: knowing when a window problem is actually a slab problem, and when a flashing gap is the real culprit behind interior drywall damage. That matters here more than in most cities.
We stock common ECO Window Systems glazing, balances, rollers, and weatherstripping for faster turnaround on repairs. When a frame is bowed, cracked, or the seal has permanently failed, we say so plainly and recommend replacement instead of selling a patch that won’t hold through the next Santa Ana event. Every job starts with a written price before any work begins, and our crew wears shoe covers and lays drop cloths on every visit. The written scope is the promise – if it is not on the paper, we have not agreed to it yet.

Common ECO Window Systems Construction Problems We Solve in Fontana
- Fogged glass and failed seals on west- and south-facing vinyl frames. Fontana’s inland valley heat sink bakes these exposures all summer. We replace failed ECO Window Systems glazing with OEM units when the frame is sound, and we re-flash the opening so the next unit doesn’t inherit the same problem.
- Stucco-to-window flashing gaps that leak during Santa Ana wind events. Wind-driven rain and dust find those gaps fast in Fontana, especially on 1980s stucco-over-frame tract homes. We remove the old sealant, install new flashing, and document the fix before the interior drywall gets patched.
- Out-of-square sliders that won’t close or lock. On the east-side grid, expansive clay shrinks and heaves under post-tension slabs, and that movement racks ECO Window Systems frames. We assess whether the window is the problem or a symptom of slab settlement, then sequence the work accordingly.
- Corrosion and pitting on aluminum ECO Window Systems patio doors. Foothill homes along Baseline get moisture trapped against aluminum components when stucco cracks and retaining walls shift. We replace corroded hardware and address the drainage path so it doesn’t return in two years.
- Retrofit inserts pulling away from stucco. On older Fontana homes, we see ECO Window Systems retrofit inserts where the original flashing wasn’t tied into the weather barrier properly. We pull the insert, correct the flashing, and reset the window so the stucco opening sheds water the way it should.
ECO Window Systems Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana’s east-side flat grid sits on expansive clay that shrinks hard during the long dry season and heaves with winter rains. That’s not a footnote – it’s the single most important factor in whether an ECO Window Systems replacement on those post-tension slab tract homes will hold square for years or start racking within months. On a recent job near Sierra and Baseline, a homeowner had fogged vinyl sliders and a diagonal crack running from the window corner across the stucco. Our tech found the post-tension slab had settled differentially on the expansive clay, racking the ECO Window Systems frames out of square. We brought in a structural engineer before ordering new units, repaired the slab edge, re-flashed the openings, and installed replacement ECO Window Systems sliders. The homeowner got working windows and a documented slab fix instead of a cosmetic patch. That’s the difference between replacing windows in Fontana and replacing them correctly.

FAQs – ECO Window Systems Construction in Fontana
Failed seals in the insulated glass unit let moisture in and break the thermal barrier, and Fontana’s 108°F+ summer afternoons accelerate that failure on west- and south-facing vinyl frames. The fix is replacing the glazing unit when the frame is still sound, or replacing the window entirely when the frame has bowed from heat and slab movement. Call (949) 850-9896 and we’ll tell you which one your home needs.
The answer depends on the condition of the existing opening. Retrofit inserts were designed for stucco-over-frame walls and can often be swapped without major stucco work, but if the original flashing is failing or the frame has racked from slab movement, the stucco around the opening will likely need repair around the new unit. We’ll tell you before we start, and the written price covers exactly what gets done.
Not always, but often enough that we budget for one on virtually any east-side remodel. If we see diagonal cracking at window corners, doors that stick seasonally, or a slab that’s visibly settled, we recommend a structural engineer’s assessment before we order replacement ECO Window Systems units. It’s the difference between a window that works for a decade and one that racks out of square in two years.
Window replacements that don’t change the rough opening size are typically handled under Fontana’s standard building permit process through the San Bernardino County Building and Safety Division, which reviews seismic detailing more closely given the city’s position near the San Andreas Fault system. We also provide Eco Window Systems in San Bernardino for homes in that county area. Impact-rated installations may require additional documentation. We pull permits and handle the inspection scheduling as part of the job.
Yes – ECO Window Systems offers configurations that can be installed to meet impact-rated standards, and we handle those installations in Fontana. The cost range for impact window installation runs $8,000 to $25,000 depending on the number of openings and the structural condition of the walls around them.
