Mr-Glass Construction in San Francisco, CA | Workshop Contractors
We’re Workshop Contractors, and we provide independent Mr-Glass sales & service across San Francisco. We install and retrofit Mr-Glass frameless shower enclosures, sliding glass doors, and replacement windows in the city’s older wood-frame homes, and we’re not a manufacturer-authorized shop — just a General Contractor in San Francisco who knows these buildings. The defining difference in our Mr-Glass work here comes down to one thing: San Francisco’s pre-1906 Victorians and Edwardians with their party walls, settled framing, and fog-belt humidity create fit-and-seal problems that a generic glass installer from the suburbs never sees. If you’re dealing with a Mr-Glass unit that binds, leaks, or corrodes faster than it should, call us at (844) 384-3361 for a free estimate.
Why San Francisco Residents Choose Us for Mr-Glass Service
We’ve been retrofitting Mr-Glass enclosures, windows, and doors across San Francisco for years, and the work has taught us something specific: this brand’s hardware behaves differently in a marine-layer climate than it does in a dry inland market. Noel Figueroa, our owner and general contractor, grew up around tradesmen who framed houses by hand, and he’s carried that same close-look standard into every Mr-Glass install we do here. We work to Mr-Glass’s published specifications, but we also know when a hundred-year-old wall means the spec alone won’t get the glass to swing clean. That combination, brand familiarity plus San Francisco building reality, is why homeowners in neighborhoods like Noe Valley, Bernal Heights, and the Richmond keep calling us back — including those who found us through our Mr-Glass service in Noe Valley.
We stock Mr-Glass sales & service parts locally for faster turnaround, and we carry OEM hinges, pivots, seals, and handles wherever they’re still available. When a discontinued part would otherwise force a full replacement, we turn to quality aftermarket hardware instead, and we tell you exactly which route we’re taking before any work starts.

Common Mr-Glass Construction Problems We Solve in San Francisco
- Corroded and stiff hinge hardware on frameless enclosures. San Francisco’s cool marine-layer air keeps bathroom surfaces damp for months at a stretch, and Mr-Glass pivot and hinge assemblies on frameless doors take the worst of it. We see hinges that seize, pivots that grind, and mounting plates that pit. We replace the hardware with OEM parts when available and re-anchor everything into solid blocking.
- Sweeps and seals that grow mold and stop sealing. A fog-belt home with a bathroom fan that’s undersized or vented into a shared wall cavity never fully dries out. Mr-Glass sweeps and side seals trap moisture, grow mold, and lose their flex. We pull the old seals, clean the glass edges, and set new OEM or matched aftermarket sweeps so the door actually closes tight again.
- Replacement panels that bind in out-of-plumb openings. A 1920s Edwardian’s walls and curbs have moved. They’re not square, they’re not plumb, and a factory-cut Mr-Glass panel sized to the original rough opening will bind on one edge or gap on the other. We template the actual opening, not the original dimensions, and shim the hardware to a verified plumb line before the glass goes in.
- Edge failures on tempered glass clamped to out-of-flat walls. When Mr-Glass hardware gets clamped onto a wall that’s curved or out of plane, the stress concentrates at the glass edge. We’ve seen panels crack at exactly that point, especially in hillside homes and basement-garage conversions where shoring has settled. We check wall flatness before mounting, and we won’t clamp glass to a wall that can’t carry it evenly.
- Shower doors that won’t close after soft-story retrofit work. Ordinance 66-15 retrofits open up ground-floor spaces, and when new bathrooms and laundry rooms land in those cleared-out basements, the framing around them usually isn’t level. A Mr-Glass door installed to the original framing binds or drifts open. We re-anchor hinge walls into solid blocking and set the enclosure against a plumb line, not the framing.
Mr-Glass Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s Ordinance 66-15 soft-story retrofit mandate is opening up ground-floor garage and basement spaces in wood-frame Victorians and Edwardians across the city, and many of those newly cleared spaces are getting permitted as bathrooms, laundry rooms, or ADU work. That’s where Mr-Glass enclosures and interior glass now land, on foundations and walls that were never framed for a level, full-height glass panel. In a Noe Valley Edwardian that looked like a two-story but was really one story over a full-height basement garage carved into the slope, our crew templated a frameless Mr-Glass shower enclosure for the new basement bath and found the curb and side walls out of plumb once excavation shoring settled. We shimmed the pivots, re-anchored the hinge wall into solid blocking, and set the glass against a verified plumb line rather than the original framing, and the door finally swung clean without gap creep. That’s the work this city actually requires, and it’s why San Francisco service area calls need a contractor who understands what’s behind the wall, not just what’s on the glass.
Mr-Glass Models & Products We Service in San Francisco
We install and service the full range of Mr-Glass product lines: frameless hinged shower door sets in the standard fixed-plus-door configuration, semi-frameless and sliding shower enclosures, interior sliding glass and closet door systems, and tempered glass panels with custom-cut replacement glass. On older units we’ll rebuild a sound enclosure with new seals and hardware rather than push a whole replacement, and we recommend replacing the panel only when the glass itself is chipped, delaminated, or no longer a safe fit. We stock common Mr-Glass hardware locally so San Francisco turnaround stays fast, and we’ll tell you plainly whether OEM or aftermarket parts make more sense for your specific unit.

AfterMr-Glass Service Pricing in San Francisco
Mr-Glass work in San Francisco is priced by the line item, not by a vague package number. Here’s what we currently see for the work we do most:

What drives cost in San Francisco more than anything is access and wall condition: lot-line row houses with tight side yards take more time to stage, and settled Edwardian framing adds shimming and blocking that a new-construction install wouldn’t need. Every estimate is free and line-itemed, so you know exactly what you’re paying for before any work starts. Call (844) 384-3361 to schedule yours.

FAQs – Mr-Glass Construction in San Francisco
Yes, in most cases we can pull the existing panel, replace the seals and hardware, and set new glass without touching the tile. We template the actual opening and shim the hardware to plumb, which matters in Edwardian homes where the curb and walls have moved. Call (844) 384-3361 and we’ll tell you what’s actually needed after a look.
The framing around the new opening has likely settled or was never set plumb to begin with. We see this on basement and garage conversions all over San Francisco: the shoring shifts, the wall drifts, and the Mr-Glass door starts binding or swinging open. We fix it by re-anchoring the hinge wall into solid blocking and resetting the enclosure against a verified plumb line. Call (844) 384-3361 for an assessment.
San Francisco’s marine layer keeps bathroom surfaces damp for much of the year, and if your bathroom fan is weak or vented into a party wall, the humidity never fully clears. Mr-Glass hinge and pivot assemblies pit and seize under those conditions. We replace the hardware with OEM parts and can also talk through ventilation fixes so the new hardware doesn’t fail the same way.
Replacing a shower enclosure or swapping like-for-like windows in San Francisco generally doesn’t require a permit, but if the opening changes size or the work is part of a soft-story retrofit or ADU conversion, the permitting picture changes. We’ll confirm what applies to your specific building before any work starts.
Yes, and this is where San Francisco row houses get tricky. Tight side yards and shared party walls mean access from outside is limited, and plumbing often runs through walls you can’t open without a neighbor agreement. We template in place, carry panels through the house, and work within the constraints the building sets.
