Ontario Window Replacement provides professional aluminum windows and thermally broken framing in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. Aluminum is the clearest case on this site of one word meaning two opposite things. In a house in Ontario it is usually the window we are removing. In a commercial building it is usually the only window that will do the job.
Start with the removal side. Most of the aluminum in Ontario housing went in between the late 1950s and the early 1980s, before anyone put a thermal break in a residential frame. Metal conducts, so the frame runs near outdoor temperature, sweats on cold mornings, and pours heat into the room on hot afternoons. Rollers wear, the interlock loses its seal, and single-strength glass rattles.
Now the other direction. Modern commercial aluminum is a different product with a polyamide strut isolating the interior face from the exterior one, so the frame no longer acts as a heat bridge. That framing is what carries a twelve foot lite, what accepts a door closer and a panic device, and what survives a public entrance that swings hundreds of times a day. Nothing else on the market does all three.
The specification conversation is different too. On a house you pick a color. On a commercial job you pick a finish system and a warranty term with it: Class I anodizing for a hard, uniform, long-lived surface, or an AAMA 2604 or 2605 powder coat when the color is not achievable in anodize. Those terms differ by years and we put the number on the estimate.
Pricing works nothing alike. Residential aluminum barely exists as a new-install category here, so the honest quote for a homeowner asking about it is a quote for something else. Commercial aluminum is priced by framing linear foot plus glazed square foot, with separate lines for the door leaf, the hardware, the finish upgrade and any after-hours labor. Two jobs of the same square footage can differ enormously on the hardware line alone.
Permitting splits hard here as well. A residential window swap is an over-the-counter permit. Touch a commercial entrance and you are in a different chapter: door width, threshold height, opening force and the hardware you are allowed to use are all fixed by rules that have nothing to do with glass. We flag that at the measure, because it decides both the price and the schedule.
There is one modern residential exception worth naming. Thermally broken aluminum in a narrow sightline is a legitimate high-end residential product, used where an architect wants a minimal frame around a very large opening. It costs more than fiberglass and it is specified, not selected from a shelf. If that is genuinely what you are after, say so and we will price it properly.
What we will not do is let the word do the arguing. If somebody quotes you aluminum windows for a house in Ontario without saying whether they are thermally broken, that quote is incomplete, and the difference between the two answers is roughly the difference between 1974 and now.
Our licensed and insured team brings the right materials and equipment to every job — center-set aluminum storefront framing in 1-3/4 by 4-1/2 inch profiles, dry-glazed EPDM gaskets and wet-glazed structural silicone joints, subsill flashing with end dams under storefront base members, tempered and heat-strengthened lites carrying CPSC 16 CFR 1201 labels, aluminum entrance doors with the 10 inch ADA bottom rail, offset pivots, top jamb closers and concealed vertical rod exit devices — and backs the work with a written workmanship warranty. We serve Ontario and nearby communities including Chino, Chino Hills, Montclair, Upland.

Materials, equipment and how we do aluminum windows and thermally broken framing
The difference between aluminum windows and thermally broken framing that lasts and aluminum windows and thermally broken framing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with center-set aluminum storefront framing in 1-3/4 by 4-1/2 inch profiles, dry-glazed EPDM gaskets and wet-glazed structural silicone joints, subsill flashing with end dams under storefront base members, tempered and heat-strengthened lites carrying CPSC 16 CFR 1201 labels, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Ontario job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the West End of the Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Ontario Chooses Ontario Window Replacement
- ✓Two estimating methods, and the quote says which one you are reading. Residential is per opening. Commercial is glazed square foot plus framing linear foot, with the after-hours premium shown on its own line instead of buried in a unit price.
- ✓We hold the CSLB C-17 glazing classification, the one that covers commercial glass. A great deal of residential window work in this region is sold by outfits that cannot legally glaze your storefront, and they rarely volunteer that.
- ✓Warranty documents are never merged. A house gets the manufacturer's residential terms. A commercial opening gets the commercial terms, which are shorter, and we would rather explain why now than have you find out in year eleven.
- ✓Permit path stated before you sign. Residential retrofit is usually over the counter. Commercial can mean plan check, an accessibility review of the path of travel, and an inspection sequence that quietly decides your schedule.
