Ontario Window Replacement provides professional glass repair and sealed unit replacement in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. Most of what looks like a window problem is a glass problem, and glass can be replaced inside the frame you already own. This page exists because that fact costs us money and saves you a great deal of it.
A fogged window has not failed as a window. The insulated unit inside it has lost its seal, the desiccant in the spacer bar has saturated, and moisture now condenses between the panes. The frame, the hardware and the weatherstrip are all still doing their jobs. We measure the sealed unit, order it to match, and swap it in the sash. The window goes back to being the window you bought.
We replace units rather than windows on any frame that is straight and any hardware that still works. That is the rule. If the sash is racked, if the vinyl has gone chalky and brittle, or if the balance system has failed as well, then replacement genuinely is the better answer and we will make that case with the reasons attached rather than as an assertion.
Commercial glass repair is a different service running on a different clock. A broken storefront lite is a security problem before it is a glazing problem, so the sequence is board-up first, measure second, order third. We secure the opening the same day with a proper temporary closure, and the space keeps trading while the permanent lite is fabricated.
Understand the lead time, because it is the thing that surprises business owners most. A commercial lite is made for your opening. Tempered glass has to be cut and edged before it is heat treated, and heat treatment cannot be shortened. Laminated adds an autoclave cycle. An oversized or specially coated lite adds more. Anybody promising you tomorrow on a fabricated tempered unit is describing something they cannot deliver.
The other commercial decision is whether the framing survives. A vehicle into a storefront usually damages the framing as well as the glass, and reglazing a bent system is a repair that fails. We will tell you which one you have, and if the frame is sound we reglaze it, which is the cheaper answer and the right one. That happens more often than most owners expect after an impact.
Residential emergency work follows the same order. We get the opening secure, then measure. Where a bedroom escape window is the broken one, we treat it as urgent rather than routine, because a boarded escape opening is a safety issue that a temporary fix should not sit on for long.
Insurance is worth a sentence. On commercial claims the carrier usually wants a scope and photographs before authorization, and we document the opening, the framing condition and the labels at the first visit so nothing has to be revisited. On residential glass, small unit replacements frequently cost less than the deductible, and we will tell you that instead of letting you open a claim you do not need.
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 glass repair and sealed unit replacement
The difference between glass repair and sealed unit replacement that lasts and glass repair and sealed unit replacement 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.
