ES Windows Construction in Fontana, CA | Rowan Construction Group Rancho Cucamonga
We provide independent ES Windows sales and service across Fontana’s residential and light-commercial properties, with pricing written before any work begins.

Why Fontana Residents Choose Us for ES Windows Service
We’ve been working our Es Windows services in Fontana since before the Auto Club Speedway redevelopment, back when the south Fontana tracts were still filling out. That timeline matters because we’ve watched how the 1000 Series aluminum single-hungs and early 3000 Series vinyl units from the 1989-1995 build-out have aged in real local conditions.
Grant Rowan trained at Los Angeles Trade-Technical College, working framing and finish carpentry before moving into full general construction. He’s put in long stretches across Rancho Cucamonga, including renovation work near the Cucamonga Winery Historical Landmark corridor, and built the kind of reputation that comes from showing up on time and leaving a site cleaner than he found it. The documentation discipline runs through everything we do: written scopes, itemized change orders, and photos at every stage so you’re not guessing where your money went.
We’re not authorized, sponsored, or endorsed by ES Windows. Our expertise is field-built, not program-certified. We stock OEM-equivalent rollers, glazing beads, weatherstrip, and sash hardware that meets or exceeds original specs, and we tell you straight when a 1990s-era unit has reached the replacement point. Under Clause 1 of The Haven Standard, the price is written before anyone picks up a tool. No exceptions.
Common ES Windows Construction Problems We Solve in Fontana

- Roller and track degradation on 2000 Series sliding glass doors. Wind-driven grit from Cajon Pass events embeds in the lower track, causing binding and eventual roller flat-spotting. We see this most often in south Fontana homes with direct exposure to the pass.
- Glazing seal failure and fogging on 3000 Series vinyl single-hungs. Fontana’s 105-110°F summer afternoons and intense UV exposure accelerate seal degradation compared to coastal markets. The fogging isn’t cosmetic; it’s a failed thermal barrier.
- Frame racking and sash misalignment on 1000 Series aluminum units. Installed in 1980s slab-on-grade homes where expansive clay soil has caused foundation movement. The window itself is fine; the opening has shifted.
- Water intrusion at mitered corners and weep-hole blockage on vinyl sliders. Wind-driven rain during Cajon Pass events forces water past degraded weatherstrip, and clogged weep holes prevent drainage. Homeowners often call roofers first.
- Anchoring failure in high-wind exposures. Standard inland fastening specs don’t account for Fontana’s wind-funnel geography. We’ve found under-driven fasteners and inadequate nailing-fin engagement on multiple south Fontana retrofits.

AfterES Windows Service in Fontana: What Local Conditions Mean for Your Equipment
Because Fontana sits in the wind funnel between the San Gabriel and San Bernardino Mountains, Cajon Pass-driven gusts over 60 mph routinely rack ES window frames and force water past degraded weatherstrip in ways that coastal LA contractors rarely encounter. This means ES window service in Fontana must prioritize wind-load anchoring, reinforced frame fastening, and weatherstrip rated for high-wind-driven rain - not just standard inland replacement specs.
In the Southridge neighborhood near Fontana’s south end, our crew tore out a set of fogged, hard-to-open 3000 Series vinyl single-hungs during a Kitchen Remodeling - Fontana project in a 1989 stucco tract home and found the rough openings had shifted from slab movement on expansive clay. We re-squared the openings, installed new ES 3000 Series units with reinforced nailing fins and high-wind weatherstrip, and the homeowner immediately noticed the windows no longer rattled during a Cajon Pass wind advisory the following week. Measure twice, document once, no surprises at closeout.
That clay soil factor is worth underscoring. The expansive soils across much of the Inland Empire floor cause recurring slab heave and foundation cracking that contractors in coastal LA rarely see at the same volume. For ES Windows installed in Fontana’s 1980s-1990s stucco-over-wood-frame homes on slab foundations, this means frame racking isn’t a matter of if but when - something we also watch for during Bathroom Remodeling in Fontana. We check for it on every service call.
ES Windows Models & Products We Service in Fontana

We work with the full ES Windows residential line that was distributed through Southern California during the 1990s-2010s build-out:
- ES Windows 1000 Series Aluminum Single-Hung Windows - common in Fontana’s 1980s tracts; we stock OEM-equivalent sash balances, weatherstrip, and screen hardware

ES Windows Service Pricing in Fontana
Every project is quoted with a flat written price and written scope before work begins. No change proceeds without a signed change order. Here’s what ES Windows work runs in the Fontana market:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
| Garage Conversion | $30,000-$80,000 |
What drives the number: unit count, opening condition (whether slab movement has racked the frame), exterior access (single-story vs. two-story), and whether we’re matching existing stucco texture or doing full surround repair. Impact window installation runs higher because of the laminated glass and reinforced anchoring required for Fontana’s wind exposure.
Our free estimate includes a full opening inspection, photo documentation of existing conditions, and a written scope with line-item pricing. Bring a competitor’s written quote and we’ll review it line by line at no charge. Call (909) 373-9612 to schedule.

FAQs - ES Windows Construction in Fontana
It’s usually both. Cajon Pass wind events drive grit into the lower track, which embeds in the roller surface and causes flat-spotting. We inspect the track profile for wear grooves and test roller rotation under load; if the track is gouged, replacing rollers alone won’t solve it. Call (909) 373-9612 and we’ll diagnose it in person - estimates are free.
Fogging between panes means the insulated glass unit (IGU) seal has failed. Fontana’s 105-110°F summer peaks and intense UV exposure accelerate seal degradation compared to coastal climates. The thermal cycling here is more extreme, and the seal compounds break down faster. We can replace just the IGU in many cases, or quote full unit replacement if the frame is also compromised.
Water intrusion at window mitered corners and weep-hole blockage often present as interior wall staining that looks like a roof leak. We test with controlled water application at the window perimeter, check weep-hole drainage, and inspect weatherstrip compression. If the water appears only when wind-driven rain hits the window face, it’s not your roof. Our photo documentation shows you exactly where the breach is.
For units under 15 years old with isolated IGU seal failure, glass-only replacement is usually cost-effective. For older aluminum or early vinyl lines with chronic seal issues, frame distortion, or balance hardware obsolescence, we recommend full replacement and quote both options honestly. Call (909) 373-9612 for an exact assessment - estimates are free.
Yes. Standard inland fastening specs don’t account for Fontana’s wind-funnel geography. We use reinforced nailing fins, additional structural screws at the jambs, and weatherstrip rated for high-wind-driven rain. This isn’t upsell; it’s what prevents the callbacks we see from jobs done to generic inland specs. The 365-Day Done Right Promise covers our Fontana installations, and we build them to not need it.
