Fontana Window Replacement provides professional aluminum window replacement in Fontana, CA for residential and commercial properties across the central Inland Empire. Fontana's postwar tracts were glazed with single-pane sliders in bare metal: no thermal break, a wiper seal worn to nothing, and a rating that would fail anything written in the last forty years. Nearly every aluminum call in this city is about those units, and about getting rid of them.
Understand what the frame is doing. Metal is a willing conductor, and an unbroken profile stretching from the stucco through to the drywall hands heat along its whole length, which in a Fontana July means a heat source sitting in your wall.
The diagnostic runs the other way in winter. An unbroken frame collects water before the glazing does, so a damp frame under dry panes on a cold morning says there is no break in the profile. It is the frame rather than the glass, and people arrive here convinced it is the other way around.
A thermal break interrupts the metal physically. What you end up with is two shells with a rigid polymer sandwiched between them and nothing conductive left spanning the joint. Some lines cast that polymer in place and cut the metal out behind it; others roll a polyamide bar in.
Here is the claim we will not make, because it is wrong. Nobody can tell you aluminum fails Title 24. The code looks at the rated figures printed on the unit, not at what the frame is made of, and thermally broken profiles carry those figures like anything else. Ask for the label and read it. We have seen this specified wrongly more often than almost any other item on a residential permit.
What the code does require is paperwork that matches. A replacement window counts as an alteration, so the CF1R naming the promised U-factor and solar heat gain goes in with the application, and a CF2R is signed after the units are set. Permitting happens at the city, and glazing in California falls under CSLB classification C-17 rather than a general license.
Where aluminum is still the right frame is the large opening and the commercial front. Thermally broken aluminum storefront systems cover the retail and industrial work here, and on a house the metal handles a wide span without the steel or aluminum reinforcement an unreinforced polymer needs in a six-foot opening.
Moving those old openings to a modern unit with a spectrally selective coating is the largest comfort change available in this housing stock, and where the frames are the original single-pane metal and every slider fights you, that is a real purchase rather than an upsell.
Our recommendation is narrower than the sales pitch. On a house here with sound stucco, square frames and two failed units, the honest purchase is two retrofits with good glass and nothing else. The frames are not the problem on that house, and opening sound stucco to prove a point costs you a patch and a paint line that never matches.
Our insured and bonded 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 aluminum window replacement
The difference between aluminum window replacement that lasts and aluminum 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 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.
