Safety glass where codes require it
US building codes call for tempered or laminated glass in sliding doors, in glass near doorways and in windows that reach close to the floor, which covers much of a large family room wall.
San Bernardino Window Replacement is a trusted San Bernardino County specialist in window replacement in Upland, CA, specializing in large custom picture windows, clad-wood units with simulated divided lites and tempered safety glass for wide openings. We offer multi-slide door walls and fiberglass replacement units.
Our team provides whole-house replacement for larger homes and style-matched sash for older bungalows, delivering big views without the summer heat for both residential and commercial projects. Every opening is measured by the installer who will set it, and we label each unit's NFRC U-factor and SHGC on the written quote before a single window is ordered.
From the glazing bars on a Craftsman sash pattern to a wall of sliding glass facing the mountains, our team handles every detail. Serving Upland together with San Antonio Heights just above it, Rancho Cucamonga to the east and Claremont to the west, we schedule each job around the age of the house as much as its address.
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.
Window replacement on Upland's north side is mostly about big glass. The city climbs as it runs north, gaining about 825 feet of elevation over 4.25 miles toward the foot of the highest part of the San Gabriel Mountains, with the unincorporated community of San Antonio Heights directly above. State Route 210 crosses this part of the city on its way between Pasadena and San Bernardino. Larger homes up the slope tend to be organised around the view and the yard, which means wide picture windows, tall stacked units and sliding or multi-panel doors. Those are the openings where a replacement either looks custom or looks like a compromise, so we plan them first.
US building codes call for tempered or laminated glass in sliding doors, in glass near doorways and in windows that reach close to the floor, which covers much of a large family room wall.
Upland's record high is 113 F, set in July 2006, and a wide south or west opening is where that heat arrives. Upland's ZIP codes, 91784 to 91786, are Title 24 Climate Zone 10, so a low-SHGC Low-E coating is the glass we price first on those walls.
A wide unit asks more of its frame. We price fiberglass and clad-wood frames for large openings on sunny walls, and explain the difference on the quote.
Arched tops, transoms and stacked fixed units over a door are built to the installer's measurements, never to a catalogue size.
Near the old centre, the window job is matching a period look. Euclid Avenue, running from 24th Street in Upland south to Philadelphia Street in Ontario, was added to the National Register of Historic Places as a historic district in 2005, and Craftsman homes and civic buildings from the late 19th century line both sides. The Madonna of the Trail statue was placed at Foothill Boulevard and Euclid in 1929. East of Euclid, between 8th Street and Arrow Highway, is the oldest part of town, once called Old Magnolia, where packing houses used to line A Street.
Homes of that age were built with wood sash. Where earlier owners swapped some of it for aluminum or vinyl, the fix is a replacement that reads correctly from the street: a wood or clad-wood unit with the right sash proportions and divided lites. Modern double-glazed sashes can carry true muntins or surface-applied glazing bars that imitate them, so the old pattern returns without going back to single-pane glass.
Where the original sash is sound and you want to keep it, we will say so and price repair beside replacement. On a house built before 1978, any work that disturbs old paint is carried out with lead-safe work practices, from plastic containment to a careful cleanup at the end of each day.

On the top streets, wildfire rules can decide which glass you are allowed to install. Alta Loma, the foothill neighbourhood next door in Rancho Cucamonga, lies in the path of the Santa Ana winds, and those winds are felt strongly across the San Bernardino valley, at speeds that can approach 60 mph. Whether your own lot is inside a Very High Fire Hazard Severity Zone is settled parcel by parcel on the state map, so we check it before the glass is specified.
If it is, the replacement windows follow California's wildland-urban interface rules, and on a house with a lot of glass that shapes the whole order: each big picture unit and each door panel on an exposed wall needs a qualifying tempered exterior pane and frame. It is far easier to plan that once across the house than to discover it at the permit counter.
The lower city has exposures of its own. Interstate 10 runs along the border with Ontario, the San Bernardino Line stops at Upland's Metrolink station, and Cable Airport sits inside the city, so bedrooms facing any of them can have laminated glass priced on that wall.
Every Upland project follows the same written path, whether it is a north side view wall or a bungalow near Euclid.
We look at the house's age and style, check the fire zone for upper lots, and note which walls take afternoon sun or freeway noise.
The installer who will do the work measures every opening, records sash patterns on older homes and checks each frame and sill.
Frame, glass package, U-factor, SHGC, grid pattern and install method are listed opening by opening, with the order date, lead time and install days.
Large units and door walls are set with the crew and equipment they need, and each sill is flashed and water tested before trim.
We walk the house with you, finish the punch list and haul the old units away.
A multi-slide or folding glass door wall on an Upland home is typically estimated at roughly $10,000 to $40,000, and arched or custom shape units usually run roughly $1,000 to $4,000 each. Clad-wood replacement windows are typically estimated around $1,200 to $2,500 per window, and fiberglass roughly $900 to $2,000 per window, so a whole-house job on a larger home is a substantial project.

Questions
Yes. We record the sash proportions and lite pattern at the measure and quote wood or clad-wood units with true or simulated divided lites to match, or repair of the original sash where it is sound.
A dual-pane unit with a low solar heat gain Low-E coating, tempered where it sits close to the floor or a door. Upland's ZIP codes are all in Title 24 Climate Zone 10, where summer heat is the main load.
That is decided parcel by parcel on the state Fire Hazard Severity Zone map. We look your address up before specifying glass, and if it is in a Very High zone the quote shows the tempered panes the rules require.
Yes. A multi-slide or folding door wall in a widened or existing opening is quoted with the frame, the glass and the track detail, and the installer measures the opening before anything is ordered.
On houses built before 1978 we use lead-safe work practices: containment, careful removal and a thorough cleanup.
Clad-wood units are typically estimated at roughly $1,200 to $2,500 per window and a door wall at roughly $10,000 to $40,000, depending on size and glass. Your written quote sets the final price.
