Mr-Glass Construction in San Antonio Heights, CA | San Bruno Construction
We’re San Bruno Construction, and we provide General Contractor – San Antonio Heights services with independent Mr-Glass window, door, and glass-enclosure work across the 91784 zip code. What separates our Mr-Glass work here from a flat-lot contractor’s is simple: on these hillside lots, the frame is only half the problem. Slope movement, drainage, and Chapter 7A wildland-interface glazing rules shape every opening we re-set or replace, so we engineer for the hill first and the glass second. Call (866) 472-1908 for a free estimate on any Mr-Glass repair, replacement, or new installation in the 91784 zip code.
Why San Antonio Heights Residents Choose Us for Mr-Glass Service
We know Mr-Glass units the way a mechanic knows a specific engine family. The sliding patio doors on older custom hillside homes, the mulled picture-window walls in mid-century builds, the frameless tempered shower enclosures in remodeled baths, the exterior door and sidelite packages on newer construction – we’ve pulled them apart on enough San Antonio Heights properties to know where each generation fails. Noel Carvalho, our owner, trained at Skyline College and has run residential projects across San Mateo County for over two decades; his approach is to find what actually moved or failed before ordering a single part. We’re independent of Mr-Glass – not authorized, not endorsed – which means we repair when a frame is sound and only replace when the opening demands it. For genuine Mr-Glass components we source direct; where OEM parts are discontinued, we use proven quality aftermarket gaskets, rollers, hinges, and sealants selected for this hillside exposure.

Common Mr-Glass Construction Problems We Solve in San Antonio Heights
Five failures show up on this hill more than anywhere else we work. Each one starts with the slope and ends with the glass.
- Racked frames and binding sashes. Hillside fill and retaining walls shift, and a Mr-Glass frame that was set dead-plumb ten years ago is now out of square by a quarter inch. The sash binds on one corner, and no hinge or roller adjustment fixes it. We re-set or re-frame the opening instead of grinding the hardware to mask a structural problem.
- Dried glazing channels and gasket failure. Intense inland heat and UV at this elevation bake rubber and sealant long before their rated life. Wind-driven rain and ember intrusion get past the frame on any wildland-interface wall. We see this on Mr-Glass doors and windows facing the San Gabriels all the time.
- Non-tempered or single-pane glass in mid-century customs. Original glazing that predates current Title 24 and Chapter 7A ignition-resistant standards. When the county inspects a new opening, that old glass will not pass. We swap it to compliant tempered units without unnecessary full-frame replacement when the frame is still true.
- Sill and flashing details that sheet water into the wall. Earlier installations assumed flat-lot grading. As slope drainage patterns changed, water found its way behind the flashing. The frame looks fine from inside. The wall cavity tells a different story.
- Shower enclosures dragging after square installation. Frameless Mr-Glass shower panels aren’t as forgiving of floor movement as everyone wishes they were. When a bathroom subfloor flexes or settles, the panel starts dragging on its hinge. We address the floor plane, not the glass.
Mr-Glass Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights is unincorporated San Bernardino County territory. That means any window or glass change that alters an opening goes through county plan check rather than a city building department. It also means the community’s high fire-hazard-severity WUI zone designation below the San Gabriel Mountains subjects exterior glazing on replacements and additions to Chapter 7A ignition-resistant requirements at the same time. The practical consequence for Mr-Glass owners here: you cannot treat a window replacement as a simple glass swap. A hillside home near the foothill grade needs tempered, ignition-resistant glazing, positive slope on every sill, and a frame that can hold its geometry when the terraced ground under it creeps. This is a county inspection reality, not a sales pitch. You can read more about the area in our San Antonio Heights service area guide. And because this page connects Mr-Glass failures specifically to that county permitting, WUI, and slope-and-drainage reality – conditions a flat-lot Upland or generic Mr-Glass page never addresses – here’s Mr-Glass work in San Antonio Heights with actual local substance behind it.
Mr-Glass Models & Products We Service in San Antonio Heights
We service the full Mr-Glass range found on San Antonio Heights homes, with Upland Mr-Glass service available nearby: sliding patio door units on older custom hillside builds, fixed picture windows and mulled window-wall assemblies in mid-century customs, tempered frameless shower enclosures in remodeled baths, and exterior door and sidelite packages on newer construction. Our parts approach is straightforward. We use genuine Mr-Glass frames, hardware, and glazing components wherever they exist. Where the OEM part is discontinued or the original detail was never right for this hillside exposure, we source quality aftermarket gaskets, rollers, hinges, and sealants. If the frame is sound and only the glazing or hardware has failed, we repair. If the opening is out of square or the wall has moved, we re-set or re-frame rather than patching a fundamentally unstable installation.

FAQs – Mr-Glass Construction in San Antonio Heights
Yes. San Antonio Heights is unincorporated San Bernardino County territory, so any window or glass change that alters an opening goes through county plan check rather than a city building department. Because the community sits in a high fire-hazard-severity WUI zone below the San Gabriel Mountains, exterior glazing on replacements and additions is also judged against Chapter 7A ignition-resistant requirements at the same time. We handle that paperwork as part of the job. Call (866) 472-1908 and we’ll walk you through what your specific opening will require.
Seasonal ground movement. Hillside fill and retaining walls expand and contract with moisture, and a frame that was dead-plumb in September can be out of square by March. If your Mr-Glass door or window sticks on one corner through part of the year and frees up in others, the frame has racked and the wall is moving — something we also address with our Mr-Glass repair in Montclair. No hinge or roller adjustment corrects that permanently. We re-set or re-frame the opening so the unit sits true in the current wall plane. Call (866) 472-1908 for an assessment.
The subfloor moved. Frameless Mr-Glass shower panels have zero tolerance for floor flex, and on hillside homes where drainage shifts the foundation slightly each season, a panel that was square at installation can start dragging within a few years. We address the floor plane – adding support or correcting slope under the shower base – rather than just re-hanging the glass. The same fix won’t work on every San Antonio Heights home; conditions vary by lot. Call (866) 472-1908 for a free estimate.
If the original frame is still square and structurally sound, yes – we can often replace just the glazing and hardware, saving the frame and a significant portion of the cost. But if the opening has moved out of square or the wall has shifted, a glass swap won’t hold, and you’d be paying twice. On San Antonio Heights hillside lots, the answer often comes down to what the county inspector will accept under Chapter 7A requirements. We assess the frame before recommending anything. Call (866) 472-1908 for that assessment.
Window replacement in San Antonio Heights typically runs $4,500 to $15,000; impact window installation lands between $8,000 and $25,000. The WUI zone absolutely changes the cost – Chapter 7A ignition-resistant glazing, county plan check fees, and the added framing work on hillside openings push the number beyond what a flat-lot replacement would cost. Shower work is more predictable: $4,500 to $12,000 for walk-in shower installation and $3,000 to $8,500 for shower replacement. Call (866) 472-1908 for a detailed quote – estimates are free, and we’ll tell you exactly what your specific opening requires.
