Ontario Window Replacement installs and replaces windows, patio doors, entry doors and storefront glass across Ontario, California. On the residential side that means vinyl, fiberglass and clad-wood units with low-E insulated glass, set either in a retrofit block frame or in a full nail-fin opening. On the commercial side it means center-set aluminum storefront framing, tempered and laminated lites, and aluminum entrance doors carrying the hardware a business actually needs.
The two are not one trade wearing different shirts. A house is quoted per opening and permitted over the counter. A suite on Holt Boulevard or a front office off Vineyard Avenue is quoted by glazed square foot and framing linear foot, plan-checked, and inspected against a different chapter of the code. Its glass is often a special order with a lead time measured in weeks rather than days.
Ontario has a distribution economy sitting next to eighty years of housing, and both of them need glass. We estimate the two separately, permit them separately and warranty them separately. Every page on this site tells you which of the two it is describing before it tells you anything else about the product.
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.
- ✓Same-day secure board-up on broken commercial glass, with the replacement lite ordered that afternoon. A boarded opening you can still trade out of beats a fast promise nobody can keep on a fabricated unit.
- ✓We will talk you out of the job when the job is wrong. A fogged sealed unit in a sound frame gets new glass, not a new window, and we quote it that way even though it is the smaller invoice.
About Ontario Window Replacement in Ontario, CA
Ontario Window Replacement works the West End of the Inland Empire out of Ontario, California, and does two different jobs under one license. One is replacing windows and doors in houses built between the citrus era and the last subdivision boom. The other is glazing tenant spaces, front offices and retail suites in a city whose economy runs on distribution.
We keep them apart on purpose. The residential estimator carries a moisture meter and a sill probe. The commercial estimator carries a profile gauge and asks who holds the lease, because that answer decides who is even allowed to authorize the work. Blending the two produces the quotes we get called in to correct, where a business owner has been promised a homeowner's warranty on a public entrance that will see two hundred cycles a day.
There are jobs we tell people not to give us. If your windows are twelve years old, the frames are sound and one sealed unit has fogged, replace nothing. Have the glass swapped inside the frame you already own.
If a landlord is obligated to repair the storefront under the lease, get that in writing before you pay anybody, us included. And if the only reason to replace is a promised energy saving, the payback on a sound window is long enough that we would rather you spent the money on attic insulation.
Our Window Services in Ontario, CA
Energy-Efficient Glass for Homes and Suites
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.
Vinyl Window Replacement
Vinyl is the correct answer for most houses in Ontario and the wrong answer for almost every storefront. That sentence is the whole page, but the reasons behind it decide whether you get a window that lasts thirty years or one that sags in eight.
Fiberglass Window Replacement
Fiberglass exists to solve three specific problems: dark colors at large sizes, thin sightlines on a wide opening, and a frame that will accept paint later. If none of those apply to your house, you are about to spend money for nothing.
Clad-Wood Windows
Clad-wood is the only window we sell for a reason that is not technical. You buy it because you want wood on the inside of the room, and everything else about the product is engineering built to make that survivable outdoors.
Aluminum Windows and Thermally Broken Framing
Aluminum is the clearest case on this site of one word meaning two opposite things. In a house in Ontario it is usually the window we are removing.
Double-Hung and Single-Hung Windows
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.
Casement and Awning Windows
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.
Horizontal Sliding Windows
More than half the windows in Ontario slide sideways. Tract builders here have used the horizontal slider for sixty years because it is cheap, it needs no swing clearance, and it fits the wide short openings that postwar floor plans favor.
Bay and Bow Window Replacement
Replacing a bay costs what it costs because of the carpentry, not the glass. What projects off your wall is a framed box with a roof, a seat and a support system, and all four of those age faster than the glazing sitting in them.
Picture and Architectural Glass
Fixed glass has no moving parts, so people assume it is the simple product. It is the one where size, weight and access decide the price, and where a residential quote and a commercial quote stop resembling each other completely.
Egress and Rescue Openings
An egress window is not a product you order. It is a dimension you have to hit, and the reason this page exists is that most people first hear about it when a garage conversion or an added bedroom fails inspection.
Laminated Security and Impact Glazing
We are going to argue against half of what this page is usually used to sell. Ontario is fifty miles inland in San Bernardino County.
Sliding Patio Doors
The patio slider is the heaviest moving thing in most Ontario houses and the one that gets used every day. When people say their door is broken, nine times out of ten the glass is fine and the rolling system underneath it has been dead for years.
French Doors
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.
Entry Doors
The front door of a house and the front door of a business have the same job and almost nothing else in common. One is chosen for how it looks and how tightly it seals.
Window Screens and Rescreening
This is the smallest invoice on the site and the one we are most often asked to inflate. A hole in a screen does not mean you need new windows, and anyone who comes to quote screens and leaves having sold a whole-house replacement has done something we will not.
Glass Repair and Sealed Unit Replacement
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.
Commercial Storefront Glass
This is the page the rest of the site keeps pointing at. Ontario runs on distribution, retail and light industry, and the glass at the front of those buildings is a separate market with its own pricing, its own permits and its own warranty terms.
Commercial Storefront, Entrance and Tenant Improvement Glazing in Ontario
Ontario's building stock is not mostly houses. It is warehouse front offices, multi-tenant retail along Holt Boulevard and Fourth Street, medical and professional suites, restaurants, and light industrial buildings around the airport and out toward Guasti.
That work is priced by glazed square foot and framing linear foot rather than by the opening, and it is inspected under a different chapter than a dwelling. We run it as its own operation, with its own estimator, its own crew and its own warranty paperwork.
- ✓Center-set aluminum storefront framing in the standard 1-3/4 by 4-1/2 inch profile, with 2 by 4-1/2 available for taller spans
- ✓Dry-glazed EPDM gasket systems and wet-glazed structural silicone joints, specified to the opening rather than to habit
- ✓Aluminum entrance doors with the 10 inch bottom rail, offset pivots or continuous hinges, closers, and panic hardware where the occupancy calls for it
- ✓Tempered and laminated safety glazing everywhere the code requires it, with the permanent label left legible for the inspector
- ✓Subsill and end-dam assemblies set before glazing, so water that gets past a gasket leaves the system instead of the tenant's floor
- ✓Same-day board-up and temporary secure closure, with the permanent lite ordered that afternoon while the space keeps trading
- ✓After-hours and weekend scheduling for occupied retail and food service, quoted on the estimate instead of added afterward
- ✓Finish specified as Class I anodized or an AAMA 2604 or 2605 powder coat, with the warranty term stated in writing

How It Works
- 1. Tell us which building it is. The first question on the phone is whether this is a house or a tenant space, because the answer changes which estimator comes out, the take-off method and the permit path. A homeowner gets an in-home measure. A tenant or property manager gets a site visit with a lift assessment and a note on whether the work has to happen after hours.
- 2. Measure, then interrogate the opening. Every opening is measured at three points for width and height and once diagonally for square. On houses we probe the sill and lower jambs for rot and for stucco patched over an old leak. On storefront we record the framing profile depth, the glazing method and the glass bite, because a one inch insulated unit will not go into a system built for quarter inch monolithic glass.
- 3. A quote that separates the two scopes. When a job has both, the residential and commercial portions are priced on their own lines with their own warranty terms attached. You see the glass makeup, frame material, finish, permit and inspection allowance, and lead time. Nothing gets folded into one per-window number that hides which half of the job is the expensive half.
- 4. Install, inspect, hand over the paperwork. Residential installs are flashed, insulated with low expansion foam and sealed before any trim goes back. Commercial openings get the subsill and end dams set before a single lite is glazed. You keep the labels, cut sheets, finish specification and both warranty documents in one packet, because the day you need them is years from now.
What Ontario Customers Say
Two other companies quoted my suite off a residential price sheet and neither one mentioned the door had to keep its panic hardware. These guys measured the framing depth, told me the glass was a four week order, boarded it that night and we never closed. The invoice matched the estimate line for line.
Replaced nine windows in a 1962 house. They found dry rot under the sill in the back bedroom during the measure and put the repair on the quote instead of surprising me on install day. The west side of the house is noticeably cooler in the afternoon now.
Our front office glass took a rock from the yard. I expected a pitch for a whole new storefront. Instead they reglazed the existing frame, matched the tint, and charged about a fifth of what I had budgeted. They took the time to explain why the frame was still good.
Honest about what a window can and cannot do. I asked about the plane noise and they said laminated glass would help but would not make it quiet, which is exactly what happened. I appreciated not being sold soundproofing that does not exist.

Frequently Asked Questions
Do I need a permit to replace windows in Ontario?
Yes. The City of Ontario Building Department permits residential window replacement, and a straight like-for-like retrofit is usually an over-the-counter or online submittal with no drawings. Commercial glazing is a different animal.
Anything that changes an opening size, alters an exit, or touches an entrance door assembly goes to plan check, and past a certain valuation it can pull in accessibility upgrade obligations along the path of travel. We tell you which of those you are in before you sign anything.
How much does window replacement cost in Ontario?
Residential retrofit vinyl windows in the West End generally run four hundred to nine hundred dollars per opening installed, with fiberglass and clad-wood well above that, and full-frame installation adding stucco and trim repair on top. Commercial is not quoted that way at all.
Storefront is priced by glazed square foot plus framing linear foot, and the things that move that number are glass thickness, tempering, the finish, after-hours labor, and whether the opening needs temporary boarding while the glass is on order.
Why does storefront glass take six weeks when house windows arrive in ten days?
Residential windows are built from a catalog of stock sizes and usually sit in a regional warehouse. Commercial glass is fabricated to your opening. A tempered or laminated insulated unit has to be cut, edged, heat treated, assembled and cured, and heat treatment cannot be hurried. If the lite is oversized or the finish is a special anodize, add more time. We board the opening so the space stays secure and trading while it is in fabrication.
Is aluminum a bad choice for windows now?
For a house in Ontario an untreated aluminum window is a poor choice and has been for decades, because the frame conducts heat straight through and sweats in winter. For a commercial opening it is often the only sensible choice, since nothing else will carry a twelve foot lite or absorb the abuse of a public entrance. The distinction is the thermal break. Commercial framing with a polyamide strut behaves nothing like the 1970s residential slider people remember.
Do you work in the neighborhoods under the airport flight path?
We do a fair amount of work under the Ontario International Airport departure corridors and in the office suites near them. Laminated glass with a thicker interlayer, or two lites of unequal thickness inside one insulated unit, does more for aircraft noise than adding a third pane does. It is a real improvement rather than a cure, and we would rather write that on the estimate than sell it to you as soundproofing.
Can one company really do both houses and commercial storefront?
Yes, but only if it runs them as two operations. The C-17 glazing classification covers both and the same license number appears on both permits. What differs is the crew, the equipment, the estimating math and the warranty document. A company that hands a business owner a residential window quote with a lifetime warranty printed on it has not understood that a lifetime warranty does not apply to a commercial building.
