Mr-Glass Construction in San Bruno, CA | Iron Beam Contractors
We install, retrofit, and repair Mr-Glass shower enclosures, frameless glass doors, and custom mirrors across San Bruno, and we’re an independent General Contractor in San Bruno, not a manufacturer-authorized dealer. What sets our Mr-Glass work apart here is that we account for the city’s fault-line geology and persistent fog moisture before we cut a single panel. If you’re planning a shower enclosure, tub-to-shower conversion, or custom glass partition in San Bruno, call (833) 756-5936 for a free estimate.
Nolan Driscoll spent two-plus decades framing and reinforcing structures across California before founding Iron Beam Contractors. He’s the kind of contractor who’ll tell you exactly what’s in the wall before we open it, not after. Our Mr-Glass sales & service work carries that same directness.
Why San Bruno Residents Choose Us for Mr-Glass Service
We know Mr-Glass enclosures and doors not from a catalog but from pulling them apart, re-templating them, and reinstalling them in San Bruno homes. The difference matters here. The city’s summer fog bank rolls in off the Pacific through the Golden Gate gap, keeping San Bruno persistently damp while a mile east in San Mateo it’s dry, and conditions differ again from Mr-Glass repair in Pacifica just up the coast. Hardware that survives fine in a sunny Peninsula town corrodes here. Hinges, handles, frame screws, all of it. We specify stainless and marine-grade fasteners on every Mr-Glass install because we’ve replaced enough pitted chrome to know better.
Nolan grew up in Orange County’s Friendly Hills area and learned the trade through the Building and Construction Technology program at Santiago Canyon College before spending over twenty years on job sites. That background means we approach glass work as a structural problem, not a cosmetic one. A shower enclosure that’s out of plumb by a quarter inch will bind, leak, and eventually crack. We check the floor, the curb, and the wall framing before we hang a Mr-Glass panel. One contractor, every phase.
We also carry OEM Mr-Glass hardware and seals where available, and we source high-quality aftermarket parts for discontinued models. If the glass is sound and only a hinge is worn, we’ll repair it. If the glass is chipped or the enclosure is fundamentally out of square, replacement is the honest answer. We tell you which, and we tell you why.

Common Mr-Glass Construction Problems We Solve in San Bruno
- Corroded hinges, handles, and frame screws from marine moisture. San Bruno’s fog doesn’t just sit on the grass. It penetrates bathrooms on north-facing walls and any room with weak ventilation. We regularly pull Mr-Glass hardware that’s seized or pitted from salt-tinged air, then replace it with marine-grade stainless and proper sealant.
- Glass panel binding or cracking from foundation movement. Homes up Crestmoor and along the ridge sit on expansive Bay Area clay. The soil swells and shrinks with seasonal moisture, and pier-and-post foundations move with it. That movement racks shower enclosures out of square, stressing the glass and snapping hardware. We re-level the curb, re-template the panel, and use adjustable hinges that tolerate minor movement.
- Seal and sweep degradation from persistent damp. Mr-Glass door sweeps and silicone seals fall apart faster in San Bruno’s fog belt than in drier Peninsula cities. The result is water leaking onto bathroom floors and mold growing in framing. We replace with marine-grade seals and often add a positive weep system to handle condensation.
- Out-of-square wall openings in 1940s-1960s homes. The flats and lower slopes of San Bruno are dominated by single-story stucco-over-wood-frame tract houses from that era. Framing has settled, studs have twisted, and walls are rarely plumb. Stock Mr-Glass panels fit poorly and create stress points. We custom-template every installation on-site rather than trusting original dimensions.
- Mismatched post-2010 and pre-1970 construction on the same block. Crestmoor’s rebuild after the 2010 PG&E pipeline explosion left a patchwork of code-current homes next to older survivors. We’ve serviced Mr-Glass installations on both, and the framing, waterproofing, and seismic details differ enough that we never assume a template from a neighbor’s house.
Mr-Glass Service in San Bruno: What Local Conditions Mean for Your Equipment
Here’s a fact most Mr-Glass pages won’t tell you: San Bruno sits directly on the San Andreas Fault, and the soil under the city is a patchwork of liquefaction-prone bay mud and Franciscan bedrock. Construction permits here routinely require geotechnical reports and seismic design details that other Peninsula cities never ask for. For Mr-Glass owners, that means your shower enclosure is not just glass hanging on a wall. It’s glass anchored to a structure that moves, creaks, and settles in ways that directly stress the frame, the hardware, and the seals. On a Crestmoor Drive hillside ranch, we were called to replace a Mr-Glass frameless enclosure that had a persistent leak at the curb. The expansive clay beneath the pier-and-post foundation had shifted the bathroom floor just enough to rack the original enclosure. We re-leveled the shower curb, reinstalled a custom-templated Mr-Glass panel with adjustable hinges, and added a positive weep system. The leak stopped and the door stopped sticking. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam. For glass in San Bruno, the same principle applies. We check what’s underneath before we cut the panel.

FAQs – Mr-Glass Construction in San Bruno
It’s the fog. San Bruno’s marine layer rolls in off the Pacific through the Golden Gate gap and lingers, keeping exteriors and poorly ventilated bathrooms damp far more often than in San Mateo or South San Francisco. That persistent moisture accelerates corrosion on hinges, handles, and frame screws, and it breaks down seals and door sweeps faster than in inland areas like Mr-Glass service in Brisbane. We specify marine-grade stainless hardware and upgraded seals on every San Bruno install. Call (833) 756-5936 for an exact assessment of your enclosure.
Yes. Post-2010 Crestmoor homes are framed to current Title 24 and seismic standards, which usually means straighter walls and newer waterproofing. But we still template on-site, because even code-current homes settle and shift on expansive clay. We never assume a panel will fit based on the neighborhood or the year built.
San Bruno’s coastal moisture tends to leave mineral deposits on glass, especially in bathrooms with weak ventilation. The single most effective step is a high-quality glass sealant applied to a clean surface, re-applied every 6 to 12 months. We can apply a protective coating during installation and recommend the right cleaner for your water. Call (833) 756-5936 if you’d like a sealant quote.
Replacing a shower enclosure with the same footprint typically doesn’t require a permit in San Bruno. However, if your project involves moving plumbing, altering the curb, or converting a tub to a shower, a permit is often required. We handle that determination during the estimate, and we pull permits when the scope triggers them.
We custom-template every panel on-site rather than ordering from the original rough opening dimensions. The 1940s-1960s stucco-over-wood-frame homes on the San Bruno flats have settled over decades, and walls are rarely plumb. We measure the actual opening in multiple places, account for the deviation, and have the glass cut to match the real space, not the blueprint. The result is a stress-free panel with hardware that aligns.
