ES Windows Construction in Westminster, CA | Moreno Valley Builders
We provide independent ES Windows construction, repair, and replacement service across Westminster, including the 92683, 92684, and 92685 ZIP codes, and we also offer ES Windows in Garden Grove. What separates our ES Windows work here is that we understand how these units fail in Westminster specifically: marine-layer condensation eating at aluminum sill tracks, Santa Ana winds driving rain past aged weatherstripping, and converted-garage additions that put stock sliders into openings they were never flashed for correctly. You get an honest repair-vs-replace call, not a pitch. Call (877) 752-3154 for a free estimate.
Why Westminster Residents Choose Us for ES Windows Service
We’re a full-scope general contractor, not a window-only shop, which means when an ES Windows unit fails in Westminster, we look at the opening the way a framer does: what’s the flashing doing, what’s the sill pitch, what’s the water path when the marine layer sits on Bolsa Avenue for three straight days. Noel Trevino, our owner and general contractor, grew up in the Sunnymead Ranch area of Moreno Valley and has spent the better part of three decades building and renovating homes across the Inland Empire. He learned framing, concrete, and mechanical systems at Riverside City College, and he’s spent years correcting the mistakes other contractors left behind. That background matters when an ES Windows Series 6000 slider in a Westminster converted garage has been leaking for years because the original opening was never tied into the accessory structure’s drainage plane.
We source OEM-style sashes, rollers, sweep locks, and insulated glass units where ES Windows profiles are still available, and we use quality aftermarket seal and hardware kits where OEM parts are discontinued. We’re independent; we’re not manufacturer-authorized, and we don’t imply we are. What we are is accountable for the entire assembly, from rough opening to final trim.
One contractor. Every phase. Call (877) 752-3154.

Common ES Windows Construction Problems We Solve in Westminster
- Marine-layer corrosion on Bolsa-area storefronts: Aluminum ES Windows sill tracks and weep-path hardware on commercial units along Bolsa Avenue collect condensation from the seasonal marine layer. Salt air accelerates the corrosion. We see pitted tracks, plugged weep holes, and stuck sliding panels. The fix is usually a track rebuild with compatible aluminum extrusions and new weep-path hardware, not a full storefront replacement.
- Flat-spotted rollers on stock Series 6000 sliders: Decades of dry-summer thermal cycling in Westminster cause vinyl slider tracks and rollers to gum or flat-spot. The window still looks fine, but it takes a shoulder to open. We replace the rollers and often the track insert while the unit is out.
- Failed corner welds and fogged insulated glass: Older ES Windows vinyl frames lose corner welds and glazing seals, showing up as fogged IGUs or water intrusion at the sill. On a fogged unit, if the frame is sound, we swap the IGU. If the corner weld has let go, the frame is done and we tell you honestly that re-glazing won’t hold.
- Santa Ana wind-driven rain past aged weatherstripping: West- and north-facing ES Windows units in Westminster take the brunt of Santa Ana winds pushing rain through sash gaps. The result is interior drywall staining below the window. We replace weatherstripping, adjust sash compression, and check the exterior flashing detail before any drywall gets touched.
- Water intrusion at converted-garage openings: Off Bolsa, added exterior staircases and separate entrances to converted garages mean ES Windows sliders often sit in openings that were never flashed as accessory structures. Water finds the gap between the unit flange and the stucco. We pull the unit, re-flash the opening, and reset it at the right sill pitch.
ES Windows Service in Westminster: What Local Conditions Mean for Your Equipment
Westminster’s housing stock is mostly 1950s to 1970s single-family tract homes and low-rise commercial strips, and off Bolsa Avenue it’s common to see secondary exterior staircases and separate entrances to converted garages or back units. That pattern is driven by multigenerational living. What it means for ES Windows work is this: those added units put ES Windows sliders and single-hungs into tight side-yards with narrow driveways where crew staging is limited, and every elevation change on an accessory structure has to be flashed and inspected as its own assembly. A stock Series 6000 slider that would be fine in a stucco tract wall fails differently in a converted-garage unit because the opening was originally a garage door or a blank wall, not a designed window rough opening. If the details aren’t right on paper, they won’t be right in the wall. We pull city permits for accessory-structure window replacements in Westminster and tie each opening into the structure’s drainage plane before we reset the unit.
ES Windows Models & Products We Service in Westminster
We work on the ES Windows Series 2000 vinyl single-hung replacement units that went into a lot of Westminster’s tract-home retrofits, the Series 6000 vinyl horizontal sliders common in both homes and small commercial build-outs, ES Windows vinyl sliding patio door systems, and the aluminum storefront and fixed-panel units you see along Bolsa Avenue. Our approach is parts-first: we match OEM-style vinyl sashes, rollers, sweep locks, and IGUs where profiles are still available, and we move to quality aftermarket seal and hardware kits when ES Windows has discontinued a line. We keep common roller sets, track inserts, and weatherstripping profiles on hand for fast turnaround in Westminster, so we’re not waiting on a freight order to get your slider working again.
For full window replacement in Westminster, our window and door portfolio also includes impact-rated and specialty systems from PGT, CGI, Therma-Tru, ECO Window Systems, and others, with ES Windows service in Huntington Beach also available. We specify those brands because performance and code compliance matter more in Santa Ana-wind-exposed openings than a brand label.

FAQs – ES Windows Construction in Westminster
Yes, if the vinyl frame and corner welds are intact, we can swap the failed IGU and re-seal the sash. If the corner weld has failed or the frame is warped, re-glazing won’t hold and the better spend is a full unit replacement. We’ll show you what we found before you spend a dollar. Call (877) 752-3154 for an exact assessment.
Westminster treats window openings on converted garages and added back units as part of the accessory-structure permitting process. That means flashings, sill pans, and drainage details get inspected. We pull the permits, coordinate the inspection, and make sure the opening meets code before the unit goes back in. It’s not a handshake job.
For Bolsa-area storefronts, aluminum ES Windows fixed-panel and storefront units hold up better than vinyl against salt air and marine-layer condensation. We specify compatible aluminum extrusions and weep-path hardware rather than retrofitting vinyl into commercial openings that see daily door traffic and coastal moisture. Call (877) 752-3154 and we’ll walk the storefront with you.
Yes, if the leak is coming through aged weatherstripping or sash gaps, a replacement unit with new compression seals stops the water. But if the leak is from a flashing failure at the rough opening, a new window won’t fix it alone. In Westminster we often find both on west- and north-facing units. We fix the opening first, then set the window.
We do. We maintain a stock of quality aftermarket seal, roller, and hardware kits that match common ES Windows profiles, and we have sources for dimensional vinyl sashes and IGUs. Where OEM profiles are still available, we use them. Where they’re not, we’ll tell you exactly what we’re substituting and why. Estimates are free at (877) 752-3154.
