Ontario Window Replacement provides professional commercial storefront glass in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. This is the page the rest of the site keeps pointing at. Ontario runs on distribution, retail and light industry, and the glass at the front of those buildings is a separate market with its own pricing, its own permits and its own warranty terms.
The system itself is center-set aluminum storefront framing, most commonly a 1-3/4 by 4-1/2 inch profile, with a 2 by 4-1/2 available where the span or the wind load calls for it. Glass sits in the framing either dry-glazed against EPDM gaskets or wet-glazed in structural silicone, and which one you get should follow the opening rather than the installer's habit. Dry glazing is faster and serviceable. Wet glazing seals better on an irregular condition.
Water management is the part nobody sees and everybody eventually pays for. Storefront framing is not watertight and was never meant to be. It is designed to collect what gets past the gaskets and drain it out, which only works if the subsill and end dams are installed before the glass. A system glazed over a missing end dam will deliver water to the tenant's floor forever, and it will look like a roof leak.
Entrances are their own discipline. A ten inch bottom rail, offset pivots or a continuous hinge, a closer adjusted to a code-limited opening force, and panic hardware where the occupancy demands it. Threshold height, clear width and maneuvering space are all fixed numbers, and if the work is significant, path-of-travel obligations can follow it into the building. We raise that before ordering, not after.
Pricing is by glazed square foot plus framing linear foot, with the door leaf, the hardware, the finish and any after-hours labor as separate lines. Finish is a real cost decision: Class I anodizing gives a hard, uniform, long-lived surface, while an AAMA 2604 or 2605 powder coat gets you colors anodizing cannot, at a different warranty term. We put the term on the estimate in years.
Schedule is driven by fabrication, not by our calendar. Tempered and laminated units are made to your dimension, and heat treatment and autoclave cycles set the floor on how fast that can happen. For occupied retail and food service we glaze after hours or on weekends and quote it that way from the start, because finding out on day one that the work cannot happen during business hours is how a project loses two weeks.
Breakage is handled as security first. We board up the same day with a real temporary closure, order the permanent lite that afternoon, and come back to glaze. A business that can keep trading behind a board is in a better position than one waiting on a promise that a fabricated lite will appear tomorrow.
The distinction we keep drawing across this whole site lands hardest here. Warranties on commercial glazing are shorter, sealed unit coverage is written against seal failure rather than breakage, and finish coverage is its own separate term. That is not a worse deal. It is an accurate one, and a quote that hides it behind residential language is a quote that has not been read carefully by the person who wrote it.
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 commercial storefront glass
The difference between commercial storefront glass that lasts and commercial storefront 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 commercial storefront glass
Quality here is not a matter of opinion — it is written down. The commercial storefront 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 commercial storefront 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.
