ES Windows Construction in Anaheim, CA | Rowan Construction Group
We’re Rowan Construction Group, an independent construction contractor that has installed and repaired ES Windows across Anaheim since 2007. Our crews work on ES Windows systems in both halves of this city: the 1950s tract homes west of the 5 and the custom hillside builds east of the 91. If you own ES Windows in Anaheim, call (470) 298-9650 for a written price before any work starts.
Why Anaheim Residents Choose Us for ES Windows Service
Grant Rowan grew up in the Crenshaw district and trained in construction technology at Los Angeles Trade-Technical College, where coursework covered framing, concrete, and project estimating before he ever swung a hammer on a paying job. That training is why we approach ES Windows service the way we approach any structural work: measure the frame, identify the failure mode, and write down the fix before anyone touches the window.
We are not an ES Windows authorized dealer. We’re independent installers and repair specialists, which means we diagnose what’s actually failing on your window rather than steering you toward a replacement because a brand program says so. For Anaheim homeowners, that independence matters. A 500 Series single-hung in a 1958 slab-on-grade ranch on the west side fails differently than the same model in a 1989 custom home off Canyon Heights Road, and we speak to both conditions in the written quote.
Common ES Windows Construction Problems We Solve in Anaheim

These are the five failure modes we see most often in this city, tied directly to local conditions:
- Pitted aluminum frames on 900 Series casements in Anaheim Hills. Wind-driven grit during fall Santa Ana events abrades the factory finish, exposing raw aluminum that then oxidizes. We sand, prime, and re-coat the affected stiles, and if the operator arm has seized, we re-machine the hinge channel and install an OEM replacement.
- Snapped channel balances on 500 Series aluminum single-hungs in west Anaheim tract homes. Original slab-on-grade homes settle with seasonal soil moisture fluctuation, and after forty or fifty years of that movement, the frame alignment shifts enough that the balances snap. We replace with genuine ES Windows OEM balances and re-shim the frame to stop the cycle.
- Warped meeting rails on 300 Series vinyl double-hungs in Anaheim Hills. South-facing walls sustain 100-plus degree afternoons during heat waves, and vinyl expands enough to warp the rail. The window won’t lock, and the sash won’t seat. We check the glazing channel, and where the vinyl has permanently deformed, we source a replacement sash rather than forcing a bad fit.
- Flat-spotted rollers on 700 Series sliding tracks near the 91 corridor. Dry Mediterranean dust clogs the roller bearings, the slider drags, and the roller eventually flat-spots. We replace the rollers with OEM parts and re-align the track. Homes near the freeway get the worst of it because that dust is constant.
- Failed original weatherstripping on all ES Windows lines. Anaheim’s dry heat bakes rubber and foam seals until they crumble. Water intrusion follows, then stucco cracking around the frame. We re-seal with material rated for the local temperature range, not a generic foam from a box store.

AfterES Windows Service in Anaheim: What Local Conditions Mean for Your Equipment
Anaheim is split by a fire code line that doesn’t exist in Fullerton, Orange, or Garden Grove. Anaheim Heights, the hillside neighborhoods within Anaheim Hills, sits in a State-designated Very High Fire Hazard Severity Zone. Any ES Windows replacement on a re-roof or addition that crosses the Chapter 7A threshold must use ignition-resistant assemblies: tempered glazing, metal screen backing, and frames flashed and sealed to resist ember intrusion. That changes how we set the frame reveal, how we seal the side jamb to the stucco, and which glazing units we specify. On the west side, that same window doesn’t face the same code review, but it does face fifty years of slab settlement and stucco repair that affects frame alignment. We write both conditions into the quote, line by line, because a window specified for one half of Anaheim may not pass inspection in the other half.
Our tech pulled a 900 Series casement out of a 1987 custom Anaheim Hills home on Canyon Heights Road where the original ES Windows operator arm had seized from wind-driven grit during a fall Santa Ana event. We re-machined the hinge channel, installed an OEM replacement operator, and reset the frame reveal to stop the stucco crack that had let ember-sized dust into the side jamb, bringing the unit back to Chapter 7A ember-resistance standards. That’s the kind of repair a manufacturer authorization doesn’t cover, because the frame movement was a local condition, not a product defect.
ES Windows Models & Products We Service in Anaheim

We service all four main ES Windows lines you’ll find in Anaheim: the 500 Series aluminum single-hung, the 700 Series vinyl sliding, the 900 Series aluminum casement, and the 300 Series vinyl double-hung. Our parts approach is repair-first on sashes and hardware. When the existing frame is structurally sound, we match genuine ES Windows OEM parts for balances, rollers, and weatherstripping. For glazing retrofits or custom sizing, we use certified aftermarket low-E and tempered units that meet Title 24. We recommend full replacement only when frame warping or WUI fire-hazard upgrades make a repair technically incomplete for Anaheim Hills Chapter 7A requirements.
We don’t stock ES Windows parts in a warehouse. We order OEM components directly and have them shipped to our Anaheim-area suppliers, which keeps turnaround predictable without pretending a discontinued 1980s operator arm is sitting on a shelf somewhere in Orange County.

FAQs - ES Windows Construction in Anaheim
No. Vinyl frames do not meet Chapter 7A ignition-resistant requirements for Very High Fire Hazard Severity Zone additions in Anaheim Hills. If your hillside addition crosses the WUI threshold, we specify aluminum frames with tempered glazing and ember-resistant screens. We’ll walk you through the code trigger points during the estimate.
Clay soil under slab-on-grade tract homes expands after winter rain, shifting the frame alignment. The sash binds against the jamb. We re-shim the frame and, where necessary, replace the channel balances. For an exact diagnosis, call (470) 298-9650, estimates are free.
Yes, in most cases. We reglaze with certified low-E or tempered units that meet current Title 24 standards while keeping the original frame. We only recommend full replacement when the aluminum frame itself is corroded, warped, or fails Chapter 7A fire-hardening review.
ES Windows are still sold through regional suppliers, and we can match existing unit specifications for additions and remodels. For Anaheim Hills additions, we verify that the existing units meet the fire code that applies to the new square footage under Chapter 7A. Call (470) 298-9650 and we’ll confirm what’s matchable before you draft plans.
We work with the remodel’s framing and Title 24 compliance from the start, whether it’s windows or Driveway & Pavers in Anaheim. New openings on a west Anaheim tract home typically require new ES Windows 500 Series or 700 Series units with low-E glazing to hit energy standards. We coordinate with the rest of the remodel so the window rough openings are framed, sealed, and inspected in one sequence, not retrofitted later.
