Ontario Window Replacement provides professional energy-efficient glass for homes and suites in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. Energy-efficient glass pays back on a schedule, and the two buildings we work on keep opposite schedules. A house in Ontario sits empty at two in the afternoon and full at eight at night. A leased suite does exactly the reverse.
That single difference decides which number on the label you should care about. For a house here, solar heat gain coefficient does more work than U-factor, because we spend far more hours pushing heat out of a building than holding heat inside one. The glass that fixes an unbearable west bedroom is a double-silver low-E coating on the number two surface, argon fill, and a warm-edge spacer. None of that is exotic and all of it is stocked.
A commercial suite has an internal load that a house does not. People, monitors, a walk-in cooler and a packaged rooftop unit all generate heat whether or not the sun is on the glass. Visible light transmittance starts to matter as much as the solar numbers, because the cheapest energy in a leased space is the lighting somebody does not switch on until ten in the morning.
Pricing follows the same fork. On a house the glass package is a line item per opening and it is one of the few upgrades we recommend without argument, because the incremental cost is small against the cost of the window itself. On storefront the glass is most of the price, so the specification conversation happens before anything is ordered rather than after.
Paperwork forks too. A residential permit carries its own energy compliance documents, prepared once and filed with the application. A nonresidential tenant improvement has an envelope specification that lives inside a much larger submittal, tangled up with lighting controls and mechanical work that has nothing to do with us. We supply our part and stay out of the rest.
Here is the part we lose jobs over. If your windows are sound double-pane units from the last twenty years, replacing them purely to save energy is a bad investment and we will tell you so at the measure. The money does more in attic insulation or in duct sealing. Replace windows when they have failed, when they leak, when they will not open, or when you are already opening the wall for something else.
Warranty terms diverge more than most people expect. A residential low-E coating is usually covered against visible deterioration for as long as the original buyer owns the house. The same coating in a commercial insulated unit carries a fixed term measured in years, and that term does not restart when the space changes tenants. We print both documents so nobody has to guess later.
What we install is decided at the opening, not in the office. West and south residential glass gets the aggressive solar package. North glass rarely justifies it. Commercial storefront gets a specification written to the actual orientation and the actual shading, because a suite under a deep canopy has a different problem from the one on the exposed corner of the same building.
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 energy-efficient glass for homes and suites
The difference between energy-efficient glass for homes and suites that lasts and energy-efficient glass for homes and suites 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.
