Mr-Glass Construction in San Bruno, CA | Toolbox Contractors
We provide independent Mr-Glass service across San Bruno, from frameless shower enclosures to custom mirrors and glass partition panels. The thing that separates our Mr-Glass work here is simple: most San Bruno bathrooms were framed in the 1940s through 1960s, and almost none of them are square. That changes how glass gets templated. If you’re dealing with a Mr-Glass enclosure that binds, drags, or leaks, call Norm Castellano and the crew at (855) 382-3257. We’ll take a look and tell you what it actually needs.
Why San Bruno Residents Choose Us for Mr-Glass Service
We’ve templated hundreds of frameless enclosures into out-of-square 1940s – 60s stucco tract bathrooms across the Peninsula. That matters more than any dealer badge. Mr-Glass builds a solid product line, but factory-nominal panels assume the opening is plumb. In San Bruno, it usually isn’t. We fix the opening first, then size the glass to the corrected wall. Norm Castellano grew up around homes that were perpetually mid-project, and he went through the construction technology program at San Bernardino Valley College before spending two decades framing, roofing, and gutting kitchens. He runs Toolbox Contractors with a tight crew, and he’s the guy you call when a previous contractor left a mess that needs untangling before real work can start. We apply that same approach to Mr-Glass service in San Bruno: find what’s actually wrong, fix the root cause, then install glass that stays put.

Common Mr-Glass Construction Problems We Solve in San Bruno
- Out-of-square openings that bind the door. 1950s stucco tract homes in San Bruno were framed fast, and bathroom alcoves drifted. A factory-nominal Mr-Glass panel binds in the corners, so hinges pull loose and door sweeps stop sealing. We re-block and square the opening before re-templating the glass.
- Doors that drop and chip at the hinge cutouts. Hillside and split-level homes near the fault trace flex with seismic movement. That racks a frameless enclosure until the door drops and the glass edge chips right at the hinge cutout. We replace the panel and reset the hardware on a plumb, reinforced wall.
- Corroded hardware and clouded lower glass. Damp coastal-fog winters and original under-ventilated bathrooms keep constant moisture on the bottom rail and hinge plates. Hardware corrodes. The lower glass clouds. We swap in OEM-spec hinges and quality aftermarket tempered panels where a custom size gets a cleaner fit.
- Furred-out or shimmed walls behind unpermitted conversions. A lot of 1950s garage and bonus-room conversions around San Bruno were never permitted, and the shower walls in those spaces are frequently furred out and never plumb. New glass templated to a moving wall will fail. We fix the wall, then cut the panel.
- Tub-to-shower conversions that need framing work before glass. When San Bruno homeowners convert an old tub alcove to a walk-in shower, the original framing often needs blocking and squaring before any Mr-Glass enclosure can anchor properly. We handle the framing, the waterproofing, and the glass in one scope.
Mr-Glass Service in San Bruno: What Local Conditions Mean for Your Equipment
Because much of San Bruno sits close to the San Andreas Fault trace, even a modest bathroom remodel that opens a plumbing wall can pull in a seismic retrofit of the existing house at plan review. That changes wall framing and blocking before any glass is templated. We’ve seen it on homes near San Bruno Park and through the west-side hills, where Fire Hazard Severity Zone and WUI requirements add another layer to what gets signed off. What this means for Mr-Glass owners is practical: if your project requires a retrofit, the original wall studs may get reinforced, reframed, or moved. Glass sized to the old wall won’t fit the new one. We coordinate that. We pull the as-built dimensions after the structural work is done, not before. On a 1950s single-story stucco ranch off the flats, the owners wanted a tub-to-shower conversion, and once we opened the alcove we found the original walls furred out and roughly an inch out of plumb. We re-blocked and squared the opening, set a new pan and tile, then templated a custom Mr-Glass frameless hinged enclosure in 3/8″ tempered glass with wall-mount hinges so the door cleared the vanity. It still closes cleanly, because we sized the glass to the corrected wall instead of the original one. That’s the difference between a panel that fits today and one that fits for twenty years.
Mr-Glass Models & Products We Service in San Bruno
We work on the full Mr-Glass line: frameless hinged shower enclosures in 3/8″ and 1/2″ tempered glass, sliding glass tub and shower doors, pivot and neo-angle corner shower units, and custom mirrors and glass partition panels. For parts, we use OEM-spec hinges, handles, and sweeps where they fit. When a custom size is the only way to get a clean fit, we order quality aftermarket tempered panels in 3/8″ or 1/2″ and cut them to the corrected opening. We carry common hinge plates, sweeps, and handle sets locally for fast San Bruno turnaround, and we won’t sell you a full replacement when re-templating a panel and re-setting hardware solves the problem.

AfterMr-Glass Service Pricing in San Bruno
Here’s what Mr-Glass-related work typically runs in the San Bruno market. These are the ranges we quote against when we scope a job:
| Service | Typical Range |
|---|---|
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Shower Replacement | $3,000 – $8,500 |
| Bathroom Vanity Installation | $800 – $3,000 |
What drives the cost is what’s behind the glass. If the wall is out of plumb and needs re-blocking, that’s framing. If we’re doing a tub-to-shower conversion, that’s plumbing, pan, tile, and waterproofing before the enclosure goes in. If the city triggers a seismic retrofit because you opened a plumbing wall near the fault trace, that’s structural. Our free estimate covers all of it: we open the wall if needed, measure the actual conditions, and give you a written line-item scope. Call (855) 382-3257 for an exact quote on your San Bruno project.

FAQs – Mr-Glass Construction in San Bruno
Replacing glass only, with no change to the shower pan, plumbing, or wall framing, typically does not require a permit in San Bruno. If you’re doing a tub-to-shower conversion or opening a plumbing wall, that’s a different scope and likely does. We tell you upfront which applies. Call (855) 382-3257 and we’ll walk you through what your specific project triggers.
In most San Bruno homes we service, a dragging door means the wall the panel is anchored to has moved or was never plumb to begin with. 1940s – 60s tract framing settles, and hillside homes near the fault trace flex. The fix is re-blocking the wall and re-templating the panel to the corrected opening, not shaving the door sweep. Call (855) 382-3257 and we’ll diagnose it on site.
Yes. We use OEM-spec hinges, handles, and sweeps where they fit. For older enclosures where the exact Mr-Glass part is discontinued, we match the finish and footprint with quality aftermarket hardware that bolts to the same cutouts. No jerry-rigging. Call (855) 382-3257 and tell us what you’ve got.
It can. Deck-side bathrooms on hillside split-levels in San Bruno see more movement and more moisture than interior bathrooms. We typically specify 1/2″ tempered glass for those enclosures and check the existing wall blocking before templating. The deck side also means wind-driven moisture, so we pay extra attention to the bottom rail seal. Call (855) 382-3257 for an assessment.
Most custom Mr-Glass enclosures run about two to three weeks from template to install, depending on glass lead time. The on-site work usually takes a day or two. We template, order the panel, and schedule the install around your timeline. Call (855) 382-3257 and we’ll give you a firm schedule for your project.
