ES Windows Windows & Doors in Van Nuys, CA | Juniper Windows Woodland Hills
We provide independent ES Windows service across Van Nuys – repair, retrofit, and full-frame replacement for the ES700, ES471, ES600, and ES800 lines. The thing that sets our ES Windows work apart in this city is simple: we know exactly what 100°F valley heat and Santa Ana dust do to these aluminum frames, and we fix the root cause rather than caulking over it. We’re not a factory-authorized dealer and we don’t pretend to be. We’re an established San Fernando Valley window and door crew that has serviced ES Windows in hundreds of homes here, and we answer the phone when you call. Reach us at (831) 508-3441.
Why Van Nuys Residents Choose Us for ES Windows Service
Van Nuys isn’t a generic suburb. The housing stock here skews 1940s-to-1960s ranch and minimal traditional, mostly wood-framed stucco, and a lot of those homes got ES Windows installed when the originals gave out. Sean Mackey, our owner and lead installer, studied building construction technology at Los Angeles Trade-Technical College and has spent the better part of two decades measuring rough openings, fitting frames, and checking seals across the Valley. He’ll tell you that an ES700 slider in Van Nuys fails differently than the same window five miles south, because the heat load and UV exposure on this side of the 101 are relentless.
We’re the crew you call when you want someone who can identify an ES window by its frame profile, not by a sticker on the glass. Our van shows up with the right OEM glazing beads, balances, and roller assemblies, or with aftermarket parts we’ve machined to match a discontinued profile. That matters in Van Nuys, where a 1958 rancher on a Sylvan Street footprint can’t wait a week for a back-ordered part while dust from a Santa Ana event blows through a failed seal.
Common ES Windows Windows & Doors Problems We Solve in Van Nuys
- Binding ES700 sliders from oxidized aluminum tracks. Early ES700 Series thermally broken sliders in Van Nuys take a pounding from UV. The anodized surface develops pitting and oxidation, the sash starts binding in the track, and by August the homeowner can’t open the window without shoulder weight behind it. We dress the track or sleeve it with stainless and replace the rollers.
- Dried-out ES800 casement gaskets that whistle and rattle. The 100°F summers bake glazing gaskets on ES800 casement and awning windows until they shrink and crack. You get dust intrusion during Santa Ana events and a constant rattle against the operator hardware. We replace the gaskets with a UV-stable compound and re-set the sash alignment.
- Cloudy ES471 picture windows from failed butyl seals. ES471 fixed windows are gorgeous until the butyl seal between glass and frame lets go. Van Nuys mornings with marine layer moisture turn those dual-pane units cloudy, and the problem doesn’t reverse itself. We do insulated glass replacement without tearing out the whole opening.
- Rusting ES600 sliding door rollers from sprinkler overspray. Van Nuys stucco walls and automatic sprinklers are a bad combination for ES600 sliding glass doors. Steel roller screws rust, the door sags, and the track wears unevenly. We replace the roller assemblies and re-flash the threshold so the next ten years don’t repeat the same failure.
- Warped mullions on forty-year-old frames. On original ES installations from the 1970s and 1980s, the aluminum mullions between fixed and operating sashes can warp from repeated thermal cycling. When that happens, the structural integrity is gone and no amount of weatherstripping will make the window seal. We’ll tell you straight when a full-frame replacement is the honest call.
ES Windows Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here’s the insight that doesn’t show up on a generic ES Windows page: in the tract-home neighborhoods west of Van Nuys Blvd, original ES Windows on 1950s minimal traditional homes are often paired with California bungalow steel casements that have rusted shut. These are narrow lots, single-story ranchers with stucco exteriors and a 4-inch trim band that gives the house its character. A homeowner calls us because the ES window is failing, and they’re worried a replacement will gut that trim. It doesn’t have to. Our retrofit preserves the 4-inch exterior stucco trim while replacing the ES units with low-E dual-pane glass, and we re-flash around the existing wood buck to stop dry rot from sprinkler moisture wicking through cracked stucco. That’s a Van Nuys-specific problem with an ES-specific solution, and we’ve done enough of these jobs to anticipate the rot before we open the wall.
Last August, our tech rolled up to a 1954 ranch on Sylvan Street near Van Nuys Blvd. The homeowner said the ES700 slider in the den wouldn’t seal. Salt-and-pepper corrosion had eaten through the aluminum track at the weep holes, and the nylon roller had disintegrated. We pulled the sash, machined a stainless sleeve for the track, installed new OEM rollers, and re-bedded the frame with UV-stable sealant. That slider now glides and locks tight even when the Santa Anas hit. That’s the standard we bring to every ES Windows job in Van Nuys.

FAQs – ES Windows Windows & Doors in Van Nuys
Yes. We replace the insulated glass unit in an ES471 picture window without removing the frame, which keeps your stucco and interior trim intact. The process takes about half a day on most Van Nuys homes. Call (831) 508-3441 for an exact quote – estimates are free.
That binding is thermal expansion. In Van Nuys, afternoon temperatures above 100°F cause the aluminum sash to expand against an oxidized or pitted track, and the window seizes until the frame cools down. The fix is track dressing or a stainless sleeve, not spray lubricant, which just attracts dust and makes it worse.
All the time. West of Van Nuys Blvd, many 1950s ranches still have their original steel casements sitting next to ES Windows that were retrofitted decades ago. We service the ES units and can coordinate the steel casement work so both window types end up operable and sealed. Give us a call and tell us what you’re seeing.
If the frame is solid and the glass package is from the last 20 years, a repair is usually the better money. If the frame shows heavy oxidation, warped mullions, or the window is a single-pane original from the 1970s, honest answer is full-frame replacement with dual-pane low-E glass. We’ll show you the condition of your window in plain terms, then give you a written price either way. Call (831) 508-3441 and we’ll take a look.
Sometimes, but the frame depth on early ES700 single-pane units wasn’t built to carry a dual-pane insulated glass unit. On many Van Nuys ranchers the better path is Window Installation - Van Nuys with a new ES700 Series thermally broken frame with low-E dual-pane glass, which gets you the energy improvement without losing the look of the original. We’ll tell you which route works for your specific window.
