Ontario Window Replacement provides professional picture and architectural glass in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. Fixed glass has no moving parts, so people assume it is the simple product. It is the one where size, weight and access decide the price, and where a residential quote and a commercial quote stop resembling each other completely.
On a house, a picture window is a single sealed unit in a frame that does not open. That is genuinely simple until the unit gets large. Past a certain size and weight, two people cannot safely carry it, the crew needs suction lifters, and a second-story or stairwell opening may need equipment outside the house. The glass is a small part of that number.
Architectural shapes are a separate line of work. Half rounds over an entry, quarter circles, trapezoids following a rake, octagons, and the tall transoms that 1990s builders in this region put above front doors. Every one of them is templated rather than measured. We make a physical template from the actual opening, because a shape that is a degree off will not go in and cannot be trimmed.
The commercial version of this page is fixed glass inside a storefront system, and it is priced by glazed square foot with the framing taken off separately in linear feet. Weight drives everything. A large tempered insulated lite is heavy enough to need a glazing robot or a crew of four with lifters, and if the opening faces a sidewalk, the work needs a permit for the sidewalk as well as for the glass.
Safety glazing is not optional and the rules are stricter than most homeowners expect. Large panes near the floor, near a door, at a stairway or beside a walking surface have to be tempered or laminated, and the permanent label has to remain legible for the inspector to read. On commercial work we photograph those labels before the frames go on, because a lite installed with the label facing inward is a lite that gets rejected.
Thermal stress is the failure mode people never hear about. A very large lite with heavy shading across part of it, a dark interior blind pressed against the glass, or a decal blocking one corner can create enough temperature difference across the pane to crack it with nobody touching it. On big architectural glass we specify heat-strengthened rather than annealed for exactly this reason, and we ask what is going in front of it.
Residential warranty on a sealed unit this size is worth reading closely, because some manufacturers reduce the term above a stated square footage. Commercial insulated glass warranties are shorter to begin with and are usually written against seal failure only, not against breakage or thermal stress. Two documents, two sets of exclusions, and we give you both rather than a summary.
Where we push back is on the house with a west-facing wall of fixed glass and no ventilation anywhere near it. Adding an awning vent above or a casement beside the picture unit costs a fraction of the glass and makes the room usable in August. A wall of sealed glass looks superb in photographs and behaves like a greenhouse at four in the afternoon.
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 picture and architectural glass
The difference between picture and architectural glass that lasts and picture and architectural glass 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.
The standards behind picture and architectural glass
Quality here is not a matter of opinion — it is written down. The picture and architectural glass work we do in Ontario follows published industry standards: NFRC sets the U-factor and SHGC ratings on every window label, and ENERGY STAR defines the efficiency thresholds by climate zone. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every picture and architectural glass project in Ontario gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
