Mr-Glass Construction in Highland, CA | Toolbox Contractors
We install, repair, and replace Mr-Glass shower enclosures across Highland, and we handle the whole job: glass, tile, fixtures, waterproofing, and the finish work around it. The thing that sets our Mr-Glass work here apart is that we build for Highland’s conditions: hard inland water, wood-frame stucco walls, foothill-lot slab movement, and the wildland-urban-interface code that flatland crews never think about. We’re Toolbox Contractors, an independent San Bernardino Mr-Glass service provider, and we’ve spent years untangling enclosures that other installers left leaking or out of square. Call (855) 382-3257 for a free estimate, and ask for Norm.
Why Highland Residents Choose Us for Mr-Glass Service
Mr-Glass enclosures are straightforward products when they’re installed right: tempered glass, clean track hardware, seals that actually meet the curb. The problem is that Highland’s conditions punish enclosures that were installed on the cheap. We know exactly what to look for because Norm Castellano grew up in Mr-Glass service in Muscoy territory just northwest of San Bernardino, went through the construction technology program at San Bernardino Valley College, and spent the better part of two decades doing framing, roofing, and full bathroom rebuilds across the Inland Empire. When a previous contractor leaves a mess, we’re the crew that gets called to untangle it.
That background matters for Mr-Glass work specifically. We know the wall studs behind Highland’s 1960s and 70s stucco tract homes, and we know what happens when hinge screws strip out of old wood framing. We keep OEM-spec rollers, hinges, sweeps, and seals on hand or on short order for Mr-Glass frameless sliders and semi-frameless pivot doors, so we’re not waiting on a parts shipment from out of state. And when OEM parts are discontinued, we match with aftermarket hardware we’ve actually tested in the field. We’re not authorized or endorsed by Mr-Glass. We’re better at telling you the truth about the product because of that. For the full picture of how we work, see our Mr-Glass sales & service page.

Common Mr-Glass Construction Problems We Solve in Highland
- Flattened rollers and derailed glides on frameless sliding doors. The top rollers on Mr-Glass frameless sliders wear into flat spots, especially in homes where the enclosure faces a hot west wall through Highland summers. The door sags, drags on the track, and eventually derails. We replace the rollers, check the track for scoring, and re-hang the door so it glides clean.
- Hard-water haze and mineral etching on Mr-Glass glass. Highland’s inland water is mineral-heavy. Without a protective coating, the glass on a Mr-Glass enclosure hazes over in a few years and looks permanently dirty. We can often restore lightly hazed glass with a deep mineral-removal and fresh coating, but badly etched glass that’s lost its temper safety gets replaced, not polished.
- Stripped hinge screws pulling out of wood-frame stucco walls. Highland’s mid-century and 1970s tract homes are almost all stucco-over-wood-frame, and the studs behind a Mr-Glass semi-frameless pivot door take a beating. Once a hinge screw strips, the door leans, and the glass stresses at the hole. We reset the hinge with a backer plate or stud-mounted blocking, not just a longer screw.
- Failed silicone seals and bottom sweep gaskets that leak at the curb. On foothill lots, slab and floor movement after seismic activity or seasonal soil shifting opens tiny gaps where the glass meets the curb. The old caulk separates, the bottom sweep stops meeting the tile, and water leaks onto the bathroom floor. We re-seal, re-sweep, and re-set the curb line so the enclosure holds water again.
- WUI-related exterior detail creep on remodel add-ons. This isn’t a Mr-Glass failure, but it’s absolutely a Highland construction problem that shows up on Mr-Glass projects: when a bathroom addition changes the building envelope, the city’s wildland-urban-interface code pulls the whole exterior into scope, and now you’re also dealing with ember-resistant vents, sealed eaves, and defensible-space details that a flatland crew in San Bernardino never has to address.
Mr-Glass Service in Highland: What Local Conditions Mean for Your Equipment
Here’s the thing most contractor pages won’t tell you, because they don’t know it: Highland’s WUI exterior-material scrutiny reaches into bathroom remodels. An added or expanded bathroom changes the building envelope of the house, and on the foothill lots along the base of the San Bernardino Mountains, inspectors scrutinize exterior detailing in a way flatland crews down the hill never see. You’re not just getting a new shower enclosure; you’re getting a re-inspection of every exterior penetration, vent, and eave junction the city thinks embers could enter during Santa Ana wind season. That means the contractor you hire for a Mr-Glass shower rebuild has to understand the full building envelope, not just the glass. We do. Our Highland service area page covers the full scope of what we handle here.
We saw it play out on a semi-rural lot toward the foothills off the base of the mountains. A Mr-Glass frameless sliding door had flattened rollers that scored the track, and the bottom sweep had stopped meeting the curb. Water had been quietly rotting the adjacent sill. We reset the stud-backed hinge and track points, installed new OEM-spec rollers and a fresh sweep, re-sealed the curb, and re-tiled the surround to match. The door glides clean now, and the enclosure holds water through the wind season. That’s the kind of repair that only comes from knowing both the product and the house it’s mounted in.
Mr-Glass Models & Products We Service in Highland
We work on Mr-Glass frameless sliding shower doors with barn-door glide hardware, which are the most common units we see in Highland bathrooms. We also service Mr-Glass semi-frameless pivot shower doors, fixed glass shower panels, and hinged single-door units. For every one of these, we match parts as close to OEM spec as we can get: Mr-Glass rollers, hinges, sweeps, and seals where they’re still available, and proven aftermarket hardware where the OEM line has been discontinued. Hardware and seals are almost always worth repairing. Glass that’s been badly etched or chipped and fails its safety-tempered integrity gets replaced. We also handle the tile and fixtures around the enclosure, which is what a lot of single-trade glass companies in Highland can’t do. One crew for the glass, the tile, the waterproofing, and the plumbing fixtures. That’s the whole point of our shop.

FAQs – Mr-Glass Construction in Highland
Yes. We source OEM-spec Mr-Glass rollers and hinges where they’re still available, and we keep common hardware on hand or on short order so we’re not waiting on a cross-country shipment. When a Mr-Glass part is discontinued, we match it with an aftermarket equivalent we’ve tested in the field, not whatever’s cheapest at the supply house. Call (855) 382-3257 and tell us what model you’ve got, and we’ll tell you what it actually needs.
It depends on how deep the etching goes. Light mineral haze from Highland’s hard water can often be removed with a proper mineral treatment and then protected with a fresh glass coating so it doesn’t come right back. But if the glass has been etched for years and lost its temper safety rating, we replace it rather than polish it and hope. We’ll tell you straight which one you’re dealing with. Call (855) 382-3257 for an assessment.
It can. Highland sits in a high-fire-severity zone at the foot of the San Bernardino Mountains near Mr-Glass repair in Loma Linda, and when a bathroom addition or expansion changes the building envelope, the city’s wildland-urban-interface code pulls the exterior into scope. You may need ember-resistant venting, sealed eave junctions, or exterior detailing updates as part of the same permit. That’s why you want a full-scope contractor, not a glass-only shop. Call (855) 382-3257 and we’ll tell you what your specific lot is up against.
Most likely slab or floor movement. Highland’s foothill lots sit on soil that shifts with seasonal moisture and seismic activity, and even a small amount of movement opens the joint between the glass and the curb. The old silicone separates, the bottom sweep stops meeting the tile, and water runs onto the floor. We re-set the curb line, re-seal the joint, and install a fresh sweep so the enclosure holds water again. Call (855) 382-3257 and we’ll take a look.
For most Highland homeowners with a tub they never use, yes. A tub-to-shower conversion with a frameless Mr-Glass door opens up the bathroom, eliminates the step-over, and costs between $3,500 and $10,000 depending on the tile, fixtures, and glass spec. It’s one of the highest-value bathroom changes you can make in a 1960s or 70s tract home. Call (855) 382-3257 for a line-item quote.
