Ontario Window Replacement provides professional double-hung and single-hung windows in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. The hung window is a transplant in Ontario. It is the eastern and midwestern default, it arrived here with tract builders copying catalogs, and it is chosen for how a house looks far more often than for how the window works.
Mechanically it is simple. One sash slides vertically in a single-hung, both do in a double-hung, and the weight is carried by a balance concealed in the jamb. Constant-force stainless coil balances are the ones that outlast the house. Block-and-tackle balances are cheaper and are the single most common warranty call on this style. Ask which one is in the window you are being quoted, because the label will not tell you.
For residential Ontario the practical argument for a double-hung is cleaning. Both sashes tilt inward, so a second-floor bedroom window can be cleaned while you stand on the carpet, with no ladder leaned against hot stucco. On a two-story house that convenience is worth real money over twenty years, and it is a better reason to buy the style than any claim about airflow.
The argument against it is also practical. A hung window gives you half an opening at most, so the same rough opening ventilates less than a casement or a slider does. In rooms where the window has to serve as an emergency escape opening, that halving is exactly what pushes a marginal opening under the required clear dimensions. We check that arithmetic before we quote, not after.
Commercially this style is rare and specific. It belongs to older institutional and multifamily buildings, and where we do replace it there, the driver is usually a facade the city will not allow us to change rather than any performance requirement. Commercial hung units are ordered with heavier balances and a shorter warranty term, and the quote is per opening plus access equipment rather than per storefront foot.
Pricing on the residential side is close to a slider of the same size in vinyl, and rises faster than a slider does in fiberglass or clad-wood, because there is more hardware in the jamb to pay for. If budget is the deciding factor and the look does not matter to you, a slider does the same job for less.
Installation detail worth insisting on: the sill has to end up sloped to the exterior and the balance pockets have to stay clear. Foam packed carelessly into a jamb will bind a coil balance, and a bound balance is a sash that will not stay up. That failure shows up months later and is always blamed on the window.
Our recommendation is narrow and we will say it plainly. Buy hung windows for a two-story house where cleaning matters, or for a street elevation in an older neighborhood where the proportions are genuinely part of the architecture. Do not buy them for a bedroom that is already tight on egress, and do not buy them because a salesperson called them traditional.
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 double-hung and single-hung windows
The difference between double-hung and single-hung windows that lasts and double-hung and single-hung windows 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.
