San Bernardino Window Replacement is a trusted specialist for window replacement in San Antonio Heights, CA and the San Bernardino County foothills, specializing in tempered dual-pane glazing, ignition-resistant frame assemblies and custom-sized view windows. We offer full-frame replacement and arched and shaped units.
Our team provides fire-zone compliant window packages, delivering safer, tighter openings on homes that face the slope for both residential and commercial projects. We measure every custom opening by hand, write the frame material and tempered glass makeup into the scope, and put the product data for the wildfire test standard on the quote before ordering.
From the tempered outer pane on a hillside bedroom to a full replacement on a custom home with a dozen non-standard sizes, our team handles every detail. Serving San Antonio Heights along with Upland, Claremont and Rancho Cucamonga, we schedule around the windy days when the foothills call for it.
Why San Bernardino Window Replacement
The installer who measures your openings is the one who sets the new windows, from the first visit to the final walk.
San Antonio Heights sits right where the valley floor meets the mountains, and that sets the terms for a window job there. The unincorporated San Bernardino County community lies at the northern edge of the Pomona Valley in the foothills of the San Gabriel Mountains, directly north of Upland, at about 2,103 feet.
The slope changes the weather. San Antonio Heights receives more rain than most of metropolitan Los Angeles because air rises against the foothills and drops its moisture, and summers are still hot and dry. Windows here see both: winter storms driven against the glass and long dry summers with the brush above the homes cured to tinder.
Its neighbours are Upland, Claremont, Rancho Cucamonga and Ontario, with Mount San Antonio looming to the north. Where a home was custom built rather than drawn from a tract plan, sizing becomes its own job, as we cover below. ZIP code 91784 falls in Title 24 Climate Zone 10, so the energy side of the glass package follows the hot inland rules even this high up.
Where a San Antonio Heights parcel sits in a Very High Fire Hazard Severity Zone, the fire rules decide the glass before taste does. The zone is set parcel by parcel on the state's fire hazard maps, so we look up your address first and write the result on the scope rather than assume it. The hazard is not theoretical. On October 23, 2008, a brush fire in the San Antonio Heights area above Upland burned about 120 acres of hillside above homes before crews held it.
California's Wildland-Urban Interface Code, Part 7 of Title 24, now carries the wildfire construction rules that used to sit in Chapter 7A of the Building Code. In a Very High zone, replacement windows in an alteration are generally required to comply. A compliant unit is generally: Dual-pane with at least one tempered pane, or Rated for 20 minutes of fire resistance, or Glass block, or Tested to the State Fire Marshal's window standard, SFM 12-7A-2
Tempered glass is about four times stronger than ordinary annealed glass and is the glass codes reach for where strength and heat resistance matter. It cannot be cut once tempered, so every pane is ordered to the measured size. Frames matter too: the assembly must be noncombustible or ignition-resistant, so the product data on your quote names the frame material and the test it passed.
Wind coming down off the San Gabriels loads big openings, and the view windows on a foothill home are the biggest openings in the house. Santa Ana winds are hot, extremely dry and can exceed 40 mph, and they are strongest where mountain terrain funnels them.
That shapes three decisions on a San Antonio Heights home:
Owners often want more glass toward the valley lights, not less. We can pair a large fixed tempered unit with operable casements on each side so the room still ventilates and the view stays open.
A foothill window has to handle a wet winter and a hot summer with one glass package. The tempered pane covers the fire side; the rest of the specification covers the other two seasons.
For the heat, a Low-E coating on the inner surfaces of the sealed unit reflects infrared, and a lower Solar Heat Gain Coefficient on the south and west walls keeps afternoon sun out of the rooms. For the rain, the work is in the install: a sloped sill pan, flashing lapped in the right order and a water test at every sill before the interior trim goes back. Heavier rain on the slope is exactly when a shortcut at the sill shows up as a stain on the drywall.
Custom homes mean custom sizes, and a custom-built house can have more non-standard openings than standard ones: arched heads, angled gable glass, corner units and openings set to the architect's grid rather than a catalogue size.
Each of those is measured by the installer who will set it, and the scope records the exact rough opening, the shape and whether the install is a retrofit inside the old frame or a full-frame replacement. Shaped tempered glass is made to order, so the measure has to be right the first time.
Owners of a second home on the property, a guest house or a small group of rentals can fold them into the same scope and schedule.
A fire-zone window package for a San Antonio Heights home is typically estimated at roughly $8,000 to $30,000 per home, depending on the number of openings and the frame. Arched and custom-shape units are usually estimated at roughly $1,000 to $4,000 each, and a large view wall with tempered glass sits at the upper end.
What moves the estimate:
All of these numbers are estimates and are subject to change after the parcel lookup and the measure, and the written quote, not this page, sets the final price.
We check the fire hazard zone for your address before anything is specified.
The installer measures each custom size and shape and photographs the existing frames.
The scope names frame, tempered glass makeup and install method, with the compliance data attached.
Where a permit is required we pull it, and the lead time is written on the quote.
Every sill is flashed and water tested, and we walk the house with you before handing over the written warranty.
Questions
It depends on your parcel. The zones are mapped address by address, not for the community as a whole, so we look up yours before writing the glass package.
Generally a dual-pane unit with at least one tempered pane in a noncombustible or ignition-resistant frame, or a unit tested to SFM Standard 12-7A-2. The product data on your quote shows which test it meets.
Not necessarily, but where the parcel is in a Very High zone, each replaced window generally has to comply. Most owners do the whole house so every opening meets the same standard.
Yes. Custom shapes are measured on site and made to order, including tempered glass, which cannot be cut after it is made.
No. Tempered glass looks the same as ordinary glass; the difference is strength and how it breaks. A Low-E coating can be chosen for high clarity on the view side.
We will not leave an opening exposed on a red-flag or high-wind day. The install schedule is written on the quote and adjusted around the weather.
From the parcel lookup, the measured openings and the chosen frame and glass. You get a free in-home measure and a written quote, and that written quote sets the final price.
Yes. A tempered dual-pane unit can carry a Low-E coating and argon fill like any other, and the NFRC U-factor and SHGC are written on the quote beside the fire compliance data.
Homeowners get a free measure at the house. Boards, managers and contractors can send plans or an opening count for a bid.
Calls only, we do not receive text messages.
