Ontario Window Replacement provides professional french doors in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. A pair of French doors gives you the entire opening rather than half of it, and it looks better than a slider from every angle. It also has three times as many things that can bind, drop or leak, and it demands more from the wall it sits in.
The mechanical difference is where the two leaves meet. There is no jamb in the middle, so the doors seal against each other and against an astragal, held by a multipoint lock that throws at the head, the sill and the strike. That mechanism is the heart of the door. A single deadbolt is why so many pairs rattle, leak air and will not latch in August.
Swing direction is the decision people regret. Out-swing gives you the whole room back and sheds water better, because the weatherstrip is on the pressure side. In-swing keeps the doors clear of a patio and out of the way of furniture on a narrow deck. In Ontario we lean toward out-swing for anything facing the afternoon sun, and toward in-swing where a screen or a security door is going on the outside.
Material follows the exposure. Fiberglass leaves are dimensionally stable and do not care about a hundred and five degree afternoon, and they are our default for a west or south wall. Clad-wood is the right answer when the interior of the room wants wood, and it is the more expensive answer both to buy and to maintain. Vinyl French doors exist and we rarely recommend them, because the material is not stiff enough for a tall unsupported leaf.
Commercially, French doors are almost never an entrance and quite often a hazard when someone tries to make them one. Public entrances have opening force limits, hardware requirements, threshold height limits and, on an exit, panic hardware. A pair of residential French doors meets none of that. Where they belong commercially is a private office, a conference room or a courtyard outside the required exit path.
Threshold and sill detailing is the difference between a door that stays dry and one that ruins a floor. The sill sits on a pan with end dams, sloped out, and the leaves close on a compression seal rather than a wiper. On a full-frame installation in stucco we cut back to framing, set the pan, lap the weather barrier over it, then hang the door.
Hardware is worth more than the finish. A quality multipoint gearbox, solid hinges rated for the leaf weight, and an astragal with a real bolt at head and sill will keep the pair aligned for decades. Cheap hardware on a good door still gives you a door that sags.
Our advice is unromantic. If you want maximum glass and minimum trouble, buy a slider. If you want the opening, the look and the way a pair of doors makes a room feel, buy French doors and spend the difference on the lock rather than on the finish.
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 french doors
The difference between french doors that lasts and french 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.
