ES Windows Construction in Westminster, CA | Polaris Contractors
We provide independent ES Windows installation and service across Westminster, including replacements, impact upgrades, and new construction for additions and ADUs. We also offer General Contractor – Westminster services for projects that need full-scope coordination. The one thing that makes our ES Windows work here different is knowing what’s behind the wall before we order the window: on the older tracts off Bolsa and Westminster Blvd, hidden unpermitted framing regularly changes the scope of a replacement. Call (855) 473-6535 for a free estimate.
Why Westminster Residents Choose Us for ES Windows Service
Most window contractors in Little Saigon can swap a unit. Few can tell you why the wall leaks, whether the header is real, or what the Building Division will flag when they inspect. Rick Sondermann started Polaris Contractors after growing up in Corona del Mar and spending decades learning construction the hard way, on the coast, where marine air eats flashings and hidden framing failures are more common than people want to admit. He learned the fundamentals at Saddleback College in Mission Viejo, and the lesson stuck: do it right the first time, the second time always costs more.
We’re independent ES Windows specialists. Not dealer-affiliated, not tied to a showroom inventory. That means we work from the product line’s own install specifications, source OEM sashes and hardware when they’re still supported, and never push a new window when a repair makes sense. Westminster homeowners call us because we treat every opening as a small construction project, not a quick swap.

Common ES Windows Construction Problems We Solve in Westminster
- Fogged or failed insulated glass on south-facing fixed and slider units. Westminster’s sun-baked stucco walls run hot all afternoon, and that repeated thermal stress breaks the IGU seal. You’ll see condensation between the panes that never clears. If the frame is sound, we replace the glass. If the frame is bowed or the sill is rotting, we replace the unit.
- Water intrusion at the head and jamb flashing on original openings. Winter rain blows against stucco walls and finds the gaps where original flashing was never lapped correctly. The stain shows up at the sill as dry-rot and peeling paint. We pull the trim, correct the flashing, install a proper sill pan, and reseal the opening.
- Slider tracks packed with grit and marine-layer damp. The cool damp mornings near the coast settle into tracks, and grit from the 22 and 405 corridors works its way into the rollers. Panels drag, jump track, or stick halfway. We clean the track, replace the rollers with matched ES Windows hardware, and realign the panel.
- Degraded weatherstripping and blocked weep holes on vinyl sliders and single-hungs. Moist morning air and wind-driven rain slip past worn weatherseal where weep holes are clogged with years of dust. The fix is straightforward: new ES Windows weatherseal, cleared weep channels, and a check that the sash still seats flush.
- Hidden unpermitted framing found behind enclosed patios and additions. This is the Westminster problem other cities don’t have at this scale. We open a wall for a window swap and find missing headers, spliced wiring, or bootlegged framing that has to be corrected before the city will sign off. We handle the framing fix as part of the job.
ES Windows Service in Westminster: What Local Conditions Mean for Your Equipment
Here’s what we’ve learned doing ES Windows work on the older tracts off Bolsa and Westminster Blvd: decades of “done cheap, done fast” enclosed patios and room additions mean a surprising number of window openings were never actually framed to carry load. On a ranch home near Bolsa Avenue, we pulled a set of fogged ES Windows vinyl sliders that had been installed into an enclosed patio years earlier and found the opening had no proper header and the stucco flashing ran backwards. The window wasn’t the problem; the wall was. We reframed the opening, corrected the head flashing and sill pan, and set new ES Windows slider units so the wall drained correctly and the inspection passed. This is the thing that separates a real Westminster window contractor from a crew that just pulls the old unit and slaps in a new one. When we give you a price, it is a real price for the actual wall we are going to find.
ES Windows Models & Products We Service in Westminster
We service the ES Windows lines typically found on Westminster tract homes and additions: the vinyl single-hung and horizontal slider series common on bedroom and bathroom openings, the aluminum-series sliding glass doors used for patio and rear-yard access, and the fixed and awning units specified for kitchen glazing and addition daylighting. Our ES Windows service in Huntington Beach covers the same product lines for coastal homeowners. For parts, we source ES Windows OEM sashes, rollers, balances, and weatherseal wherever the profile is still supported. When OEM is discontinued, we use matched aftermarket hardware only after verifying the fit against the original extrusion. We stock common rollers, balances, and weatherseal for the most frequent Westminster models, which keeps most repair turnarounds short.

FAQs – ES Windows Construction in Westminster
Yes. We handle it all the time. The difference is that we will reconcile the framing and flashing with the City of Westminster’s Building Division as part of the window job. That means correcting missing headers or spliced wiring if we find it, then setting the new ES Windows units so the inspection passes. The window and the wall get fixed together. Call (855) 473-6535 for an exact quote, the estimate is free.
The south-facing stucco walls on Westminster ranches soak up sun all afternoon, and that heat stress eventually breaks the seal on the insulated glass unit. Once the seal fails, the argon or krypton fill escapes and condensation collects between the panes. If the frame is still sound, we replace the IGU with a factory-matched ES Windows unit. If the frame is bowed or the sill is failing, replacement makes more sense.
Usually, yes. Grit from the streets and damp marine air get into the track, the rollers seize, and the panel drags or jumps. We clean the track, replace the rollers with matched ES Windows hardware, and realign the panel. Most slider repairs are done in one visit. Call (855) 473-6535 and we’ll tell you what your specific situation needs.
Yes. We run ES Windows fixed, awning, and slider units as part of larger addition and ADU projects across Westminster, including the permitted work the city requires on the narrow lots around the 92683, 92684, and 92685 ZIP codes. We also handle Stanton ES Windows service for homeowners just outside our core area. Because Polaris Contractors is a full-scope general contractor, we sequence the window openings with framing, stucco, roofing, and electrical so the project moves as one job, not five.
The most common cause in Westminster is failed head and jamb flashing on the original opening, not the window itself. Winter rain driven against the stucco finds the gap where the flashing was never lapped correctly, and the water runs down to the sill and into the wall. We remove the trim, correct the flashing and sill pan, and reseal the opening. If the frame is already rotted at the sill, we recommend replacing the unit. Call (855) 473-6535 to have us look.
