Ontario Window Replacement provides professional sliding patio doors in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. The patio slider is the heaviest moving thing in most Ontario houses and the one that gets used every day. When people say their door is broken, nine times out of ten the glass is fine and the rolling system underneath it has been dead for years.
Original doors in this housing stock are frequently aluminum with steel wheels running on a soft aluminum track. The wheels flatten, the track mushrooms, and the panel starts gouging its own path. New rollers alone will not fix that, because the surface they run on is destroyed. A stainless track cap over the damaged sill plus tandem rollers will, at a fraction of the cost of a new door.
When replacement is right, the decision is frame material and panel count. A vinyl or fiberglass slider is the sensible residential default. Panel configuration changes the price more than most people expect: a two panel door where one side slides, a three panel where the center opens, or a large multi-slide that stacks or pockets into the wall. Multi-slide is a specified product with a structural header requirement, not a catalog item.
Glass in a patio door is always safety glazing, and the label is not decorative. If your existing door has an unlabeled pane, someone replaced it with the wrong glass at some point, and that is worth correcting whether or not you replace the door.
The commercial version is not this product at all. A business does not get a residential slider on a public entrance, because the entrance has to satisfy opening force, threshold height and hardware rules that a residential slider cannot meet. Where sliding doors do appear commercially it is at patio service areas, restaurant courtyards and hotel rooms, ordered on commercial framing with commercial hardware and a warranty measured in years.
Restaurant work in Ontario runs into this constantly. A courtyard or patio enclosure looks like residential glass and is inspected as commercial construction, which means our quote covers plan check time, safety glazing throughout, and a hardware specification that matches the rest of the building. Priced as a residential door, that job goes wrong in week one.
Installation is unforgiving because of the weight. The sill has to be fully supported and dead level along its whole length, since a slider sill that sags a sixteenth of an inch in the middle will bind the panel for the rest of its life. On a full-frame replacement we set a sill pan with end dams first, because the threshold of a patio door is the lowest point in the wall and water finds it.
If your door still rolls acceptably and only the glass has fogged, do not replace the door. Have the sealed unit swapped in the panel. It is a morning of work, the door goes back to how it was, and the difference in cost between the two answers is large enough that anyone who does not offer you the smaller one is not being straight with you.
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 sliding patio doors
The difference between sliding patio doors that lasts and sliding patio 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.
