Ontario Window Replacement provides professional storefront window installation in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. There are two ways a storefront gets built, and the fork comes at order stage rather than on site. Either the aluminum turns up as lengths to be cut and put together inside your opening, or it turns up as completed frames with the glass already in them.
Assembling in place is what most of the work around this city is. Members are cut to the opening, corners joined, the whole frame squared and anchored, and the glass set afterward from one face. The installer is making a frame fit a wall that has been standing for decades.
Factory-glazed units, sold as pre-glazed or unitized, invert that completely. The frame is built and glazed under a roof, in jigs, by people doing nothing else all day, then delivered as a finished panel and set. Glazing done on a bench is better glazing, and the install is quick because the slow part already happened elsewhere.
The catch is dimensional. A finished panel cannot be scribed, packed out or trimmed once it reaches your address, so the opening has to be surveyed and the survey has to be right.
On a new or rebuilt opening that is straightforward. On a forty-year-old concrete opening it is a risk somebody has to own in writing.
Which is why we survey before deciding rather than afterward. Width at head, middle and base, plumb at both jambs, level across the bottom, and the depth available for the framing to sit in. Where those figures disagree with each other by much, built in place is the right answer and nobody should be talked out of it.
There is a middle route worth knowing. Frames can be made up in the shop and glazed on site, which keeps the joinery accurate while leaving the panes until last. On a long distribution or retail frontage that is often the sensible compromise, and it is rarely offered unless somebody asks.
Pane size interacts with all of this. A pre-glazed panel carries its glass through the whole journey, so size, weight and handling become a delivery problem as well as a glazing one, and a wide pane can need equipment on site purely to get it into position.
The survey belongs in the permit file. A frontage alteration is reviewed by the city on drawings showing the framing, the glass and the anchorage, and where a panel is being fabricated to a measured opening, those recorded dimensions are what the fabrication is defended by later on.
The honest close, which costs us the bigger ticket. Where existing framing is straight, properly anchored and still draining, the right purchase is glass and gaskets into what you already own, whichever way it was originally built. New framing is the answer when the aluminum itself has failed, and we will say which after measuring.
Our insured and bonded 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 storefront window installation
The difference between storefront window installation that lasts and storefront window installation 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.
