ES Windows Construction in Ontario, CA | Polaris Contractors
We provide independent ES Windows service in Montclair and across Ontario, from glass and hardware replacement to full-frame window installation. The thing that makes our ES Windows work here different is that we know how Ontario’s soil and wind actually affect window openings: in the 91764 ZIP, homes built on former citrus groves shift in ways that wreck perimeter seals and rack frames long before the window itself fails. That local knowledge is why Ontario homeowners call us instead of a generic window shop. We service every ES Windows product line, and we stock what these neighborhoods actually need. Call (855) 473-6535 for a free estimate.
Why Ontario Residents Choose Us for ES Windows Service
Our crews have installed and serviced ES Windows aluminum and vinyl window and door systems across the Inland Empire for years, including the tilt-up commercial shells and postwar ranch remodels that define Ontario. Rick Sondermann, our owner, learned the trade from a finish carpenter father who believed in doing things once and doing them right, and that philosophy drives how we approach ES Windows work. We stock OEM ES Windows glass units, rollers, weatherstrip, and hardware for the models Ontario homes actually have installed, so we’re not ordering parts blindly and making you wait. We’re an independent contractor and are not authorized, sponsored, or endorsed by ES Windows. Our credibility comes from field experience, not a manufacturer badge. When an ES Windows frame is square and the thermal break is intact, we repair it properly. When the frame is compromised, we tell you straight and recommend replacement. ES Windows sales & service is core to what we do, and we back it with the same accountability we bring to every full-scope remodel.

Common ES Windows Construction Problems We Solve in Ontario
- Aluminum frame and thermal-break seal degradation from heat and Santa Ana wind cycles. Ontario’s hot, dry summers expand aluminum frames repeatedly. Over years, gaskets shrink, thermal breaks fail, and air and water start moving through the frame. We see this most on west and south elevations where solar load is heaviest.
- Fogged insulated glass units on vinyl and aluminum sliders. Failed seals between the panes are the single most common ES Windows failure in Ontario, especially on south-facing sliders in 1950s to 1970s ranch homes where afternoon sun beats on the glass. We replace the IGU with OEM glass when the profile is still in production.
- Roller, track, and weatherstrip wear on sliding patio doors. High-use family rooms in those same ranch homes put years of traffic on ES Windows patio sliders. Hard operation and water intrusion at the sill are usually roller and weatherstrip failure, not the whole door.
- Stucco-to-frame perimeter cracking around aluminum units. Ontario’s soil drying and foundation movement racks window openings, and the stucco perimeter seal cracks as the frame moves. Caulking over it hides the problem for a few months. We fix the racked opening first, then restore the seal.
- Out-of-square openings from former citrus grove subsidence. In the 91764 ZIP, buried irrigation lines and organic debris from the old groves decompose and shift soil under slabs. Window and door openings distort, so new glass or full units won’t seat correctly until the opening is re-plumbed and re-shimmed.
ES Windows Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s 91764 ZIP sits on ground that used to be citrus groves. Before the subdivisions, irrigation pipes ran through that soil, and tree roots left organic matter that’s still breaking down decades later. When that buried material shifts or compresses, slabs move slightly, and window and door openings go out of square. We routinely find ES Windows frames that were installed square and are now racked by a quarter inch or more, which is enough to crack stucco, break the perimeter seal, and make sliders bind. Before we replace any ES Windows in Upland or this ZIP, we check and re-shim the frame. Installing new glass into an out-of-square opening just transfers the stress into the new unit, and you’ll be back in the same spot in two years. We’d rather fix the opening once and install the window correctly.
ES Windows Models & Products We Service in Ontario
We service the full ES Windows residential lineup across Ontario: the 4500 Series aluminum single-hung, the 800 Series vinyl single-hung and slider, aluminum horizontal sliding windows, and vinyl patio sliding doors. For each line, we source OEM ES Windows glass units, rollers, weatherstrip, and hardware where the exact profile is still available. When a system is discontinued, we use matched aftermarket components that fit the profile correctly, not generic parts forced into place. We keep common ES Windows hardware in local inventory for fast Ontario turnaround, and we’ll give you a straight answer on whether repair or replacement makes more sense for your specific windows. When frames are sound but glass or hardware has failed, we repair. When thermal breaks, sills, or perimeter conditions are compromised, we recommend full replacement.

AfterES Windows Service Pricing in Ontario
What you’ll pay depends on whether we’re repairing hardware and glass or replacing full units, and on the condition of your openings. Here’s what Ontario homeowners can expect for the work we’re most often called for:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
Repair work like glass unit replacement, roller swaps, or weatherstrip replacement typically runs lower than full window replacement, and we’ll quote that precisely once we’ve seen the window. A free estimate from us includes a look at the frame, the opening, and the perimeter seal, not just the glass. Call (855) 473-6535 and we’ll come out, assess what you have, and give you written line-item pricing before any work starts. We don’t change the price once the job is underway.

FAQs – ES Windows Construction in Ontario
Is Polaris Contractors an authorized ES Windows dealer or service provider?
No. We’re an independent contractor serving Ontario, and we are not authorized, sponsored, or endorsed by ES Windows. We stock OEM parts where available and we’ll tell you plainly when a repair isn’t worth doing. Our authority comes from years of installing and servicing ES Windows in San Antonio Heights and across the Inland Empire, not from a manufacturer’s stamp.
Do you use OEM ES Windows parts or aftermarket components?
We use OEM ES Windows glass units, rollers, weatherstrip, and hardware whenever the exact profile is still in production. When ES Windows has discontinued a line, we source matched aftermarket parts that fit the frame correctly. You’ll always know which we’re using and why before we order anything.
How long does ES Windows service take in Ontario?
Most glass unit replacements and hardware repairs are done the same day once parts are in hand. Full window replacement across several openings typically takes one to two days of on-site work, depending on the number of units and whether we need to address out-of-square openings. We’ll give you a straight schedule at the estimate, and we stick to it.
Which ES Windows models do you service?
We service the 4500 Series aluminum single-hung, the 800 Series vinyl single-hung and slider, aluminum horizontal sliding windows, and vinyl patio sliding doors. If you’re not sure which model you have, we can identify it from the frame and glass markings during the estimate.
If my Ontario home’s window openings are out of square from foundation movement, can you still install new ES Windows units?
Yes. We re-plumb and re-shim the frame opening before installing any new unit. Installing new glass or a full window into a racked opening just stresses the new unit and voids its effective life. We fix the opening first, then install the ES Windows unit square, sealed, and operating correctly. Call (855) 473-6535 to schedule your free estimate and we’ll assess the openings directly.
