Ontario Window Replacement provides professional entry doors in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. The front door of a house and the front door of a business have the same job and almost nothing else in common. One is chosen for how it looks and how tightly it seals. The other is regulated in nearly every dimension it has.
Take the house first. A residential entry is a slab or a prehung unit in fiberglass, steel or wood, and in Ontario fiberglass wins most arguments. A west-facing wood door in this climate moves, checks and needs refinishing on a schedule people do not keep. A fiberglass slab with a molded grain holds its finish, does not warp against an afternoon that hits triple digits, and takes a decorative glass insert without any of the maintenance.
Prehung versus slab is the real decision and it is about the jamb. If your existing jamb is square, sound and correctly flashed, a slab is far less work and less money. If the jamb has moved, the threshold has rotted, or the door never sealed at the top corner, a prehung unit with a new sill is the honest fix. We say which one you have after a level goes on it.
Glass changes the code picture even at a house. Sidelites and full-glass doors mean safety glazing, and the panel next to a door has specific requirements. If you have an unlabeled pane in a sidelite, it was replaced by somebody who did not know that, and it should be corrected.
Commercially this is a different trade with a different vocabulary. A public entrance is a narrow, medium or wide stile aluminum door with a ten inch bottom rail, hung on offset pivots, butt hinges or a continuous hinge, with a closer set to an opening force the code fixes and hardware determined by the occupancy. If the door serves as an exit for enough people, it needs panic hardware and it must swing in the direction of travel.
None of that is negotiable and none of it is priced like a house. A commercial entrance is quoted as framing, door leaf, glass, and hardware as separate lines, and the hardware line can exceed the door. Add a card reader, an electric strike or an automatic operator and the job pulls in an electrician and a different inspection. We tell you that at the walkthrough, because it is the part that moves the schedule.
Accessibility is the piece business owners are most often blindsided by. Threshold height, clear width, maneuvering clearance on both sides and the force needed to open all have numbers attached, and if the work is significant enough, upgrading the path of travel can come with it. We are glaziers, not plan checkers, but we know when to tell you to get a design professional involved before ordering.
The warranty split is stark and worth stating. A residential entry door carries consumer terms measured against normal household use. A commercial entrance carries a much shorter term precisely because it is going to swing hundreds of times a day, and no manufacturer will pretend otherwise. Anyone quoting you a lifetime warranty on a storefront door has printed the wrong document.
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 entry doors
The difference between entry doors that lasts and entry doors 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.
