Fontana Window Replacement provides professional glass repair & insulated glass units in Fontana, CA for residential and commercial properties across the central Inland Empire. This is the cheapest page on the site and the likeliest to save you money, because of one distinction in the energy code. Replacing only the glazing or sash while the frame stays put is a repair. Changing the frame is an alteration, and that pulls in the certificates.
So if your frames are structurally sound and your actual complaint is a failed seal, a fogged unit or a cracked lite, the honest answer is almost never a whole-house replacement. It is reglazing, and it is a fraction of the cost with none of the permit paperwork. We would rather do four of those in a morning than sell one job somebody did not need.
Failed insulated glass units are the common case here. The sealant around the perimeter of a dual-pane unit eventually loses its grip, the desiccant in the spacer saturates, and moisture condenses between the lites where you cannot wipe it. That haze in the morning sun is a dead unit, and the frame around it is usually fine. It is also progressive, so a unit that fogs lightly this spring will be worse by next summer.
Replacing the unit means measuring the daylight opening and the overall unit size, matching the glass thickness and the airspace, and specifying the coating and spacer for the replacement. We normally take the opportunity to move an old clear or hard-coat unit to a spectrally selective soft-coat and a warm-edge spacer, which is a straight upgrade for very little extra on the same visit. The frame never knows the difference.
Broken glass has its own decision tree. A single cracked lite in a dual-pane unit means the whole sealed unit gets replaced, because you cannot break the seal to change one side of it. Tempered glass that has shattered into fragments has to be replaced with tempered, and the small etched stamp in a corner tells you what it was.
That stamp matters. Glazing in specific locations near doors, in tub and shower enclosures, near walking surfaces and at low sill heights has to be safety glazing, tempered or laminated. If a pane is being replaced in one of those locations, it goes back as safety glass regardless of what was there before, and if what was there before was annealed, that is a defect being corrected rather than an upsell.
Where reglazing is not the answer is when the frame itself has failed. Rotted wood sills, aluminum frames with corroded corners that will not hold square, vinyl that has warped past the point where a sash seals, or a unit whose hardware has been discontinued for twenty years. At that point you are pouring good glass into a bad frame and the replacement conversation is the right one.
We will look at both and tell you which one you are in. A large share of the calls that come in asking for new windows leave with a reglazing quote instead, and that is a fine outcome. It is a smaller invoice, it is the right answer, and the houses where it is not the right answer are usually obvious within about ten minutes of walking the perimeter.
Our licensed and insured team brings the right materials and equipment to every job — spectrally selective soft-coat low-E glass, argon-filled insulated glass units, warm-edge stainless and foam spacers, welded multi-chamber vinyl frames, pultruded fiberglass lineals, aluminum-clad wood sash — and backs the work with a written workmanship warranty. We serve Fontana and nearby communities including Rialto, Bloomington, Colton, Grand Terrace.

Materials, equipment and how we do glass repair & insulated glass units
The difference between glass repair & insulated glass units that lasts and glass repair & insulated glass units that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with spectrally selective soft-coat low-E glass, argon-filled insulated glass units, warm-edge stainless and foam spacers, welded multi-chamber vinyl frames, 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 Fontana 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 central Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
