Ontario Window Replacement provides professional casement window replacement in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. A casement seals better than anything else we install, because the sash is pulled against a compression gasket by the lock rather than sliding past a brush. If your priority is a tight house, this is the window. Everything else on this page is about the costs of that decision.
The sealing advantage is mechanical and it is real. A multipoint lock draws the sash into the frame at several points along its height, and the gasket compresses instead of wiping. Sliders and hung windows cannot do this by design. On the exposed west side of a house near the foothills, where afternoon air movement is a fact of life here, a casement is noticeably quieter and noticeably tighter.
The costs are hardware and swing. Every casement depends on an operator gearbox, a hinge track and a lock mechanism, and those parts are consumables measured in decades rather than lifetimes. We specify type 316 stainless hinge tracks and keep operators in stock, because the most common casement service call is not glass at all. Swing matters too: a sash opening over a walkway or a side yard becomes a hazard.
An awning is that mechanism rotated ninety degrees, and it answers a problem the West End genuinely has. Hinged at the top and cranked outward at the bottom, it sheds the rain that arrives sideways in a February storm while staying open, and it works high on a wall above a counter or a fixed picture unit. Over a kitchen sink it beats a slider for reach, since the crank is closer than the sash.
Commercially, awnings do serious work and casements almost none. Storefront systems are mostly fixed glass, and where a suite needs operable ventilation it is usually a row of awning vents set into the framing above eye level, ordered as part of the storefront package rather than as separate windows. Those vents are priced within the storefront take-off, carry the commercial framing warranty, and often need a hardware specification that matches the building's other openings.
Residential pricing runs above a slider of equal size and below a comparable clad-wood unit, and the spread widens as the sash gets bigger, because a large casement needs a heavier operator to move it. Very wide casements are a bad idea for that reason. Past a certain width we will steer you to two narrower sashes instead of one wide one, and we will explain the arithmetic rather than just quoting it.
Egress is where a casement earns its price twice. Because the sash swings fully clear, a casement delivers nearly the whole rough opening as usable clear space. In a bedroom that fails the required opening dimensions with a slider, swapping the style is frequently cheaper than enlarging the hole in the wall.
The honest limitation is screens. A casement screen sits on the interior, which means it is inside the room where insects, dust and small hands all reach it. People who have only owned sliders are sometimes surprised by that, and it is better said now than discovered on install day.
Our insured and bonded 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.

Materials, equipment and how we do casement window replacement
The difference between casement window replacement that lasts and casement window 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.
