Mr-Glass Construction in Montclair, CA | Workshop Contractors

We provide independent Mr-Glass sales, installation, and repair service throughout Montclair, CA. Our crews template, set, and service Mr-Glass frameless shower enclosures, mirrored doors, and tempered patio glazing every week. What makes our Mr-Glass work different in Montclair is local: we know how these openings behave inside 1950s – 1970s tract homes with walls that have shifted out of square over six decades. If you need a Mr-Glass shower door re-hung, a unit replaced, or a custom enclosure built into a converted garage bath, call us at (844) 384-3361 for a free estimate.

Why Montclair Residents Choose Us for Mr-Glass Service

Noel Figueroa, our owner and general contractor, learned framing in the Inland Empire before he ever touched a glass panel, and that background matters here. Most glass shops measure an opening and order a door. We walk into a Montclair ranch house, look at the wall framing behind the tile, check whether the curb has settled, and then decide what the glass should hang from. In a city where nearly every home dates from the postwar era, that difference shows up quickly. We’re not authorized or sponsored by Mr-Glass, which means we can tell a homeowner the truth about whether to repair, re-template, or replace. We source OEM-compatible hardware where it fits and use quality aftermarket rollers, sweeps, and seals where an original part has been discontinued. Montclair service is local to us. Call (844) 384-3361 and you’ll speak with someone who has actually worked on homes in the 91763.

Common Mr-Glass Construction Problems We Solve in Montclair

• Shower doors binding at the bottom sweep. Original framing in mid-century Montclair tract homes was rarely plumb or square, and after decades of stucco movement, frameless Mr-Glass panels set into an out-of-square alcove will drag at the sweep and creep out of hinge alignment. We re-template the opening, correct the curb and blocking, and reset the glass so it closes against the jamb without a shim showing.
• Flat-spotted sliding rollers and corroded tracks from hard water. Montclair sits on mineral-heavy water, and bathrooms in older tract houses stay damp through the hot-dry summer cycle. Builder-grade roller assemblies corrode and flat-spot, which makes the door jump and grind. We replace rollers and tracks with stainless or quality aftermarket hardware sized for the existing extrusion.
• Seal and gasket failure at the shower curb. In garage conversions and room additions across Montclair, a bath is often set against a framed wall that was never perfectly vertical. Moisture gets under the original curb, seals fail, and the glass starts to wick water onto the floor. We pull the door, re-bed the curb, replace the seals, and re-hang the unit.
• IGU seal failures in south- and west-facing stucco walls. Montclair’s Santa Ana wind events and hot summer sun put real thermal and wind load on tempered Mr-Glass window and patio-door units. When a dual-pane seal fails, we order replacement insulating glass to match the original frame and set it back in place.
• Sash rot and frame racking on patio doors. In a stucco tract house, a patio door that racks out of plane will not hold a Mr-Glass panel cleanly. We square the rough opening, install new framing where needed, and then set the glazing unit so the panel operates without binding.

Mr-Glass Service in Montclair: What Local Conditions Mean for Your Equipment

On the small postwar lots near Montclair’s 91763 core, original detached garages often sit within inches of the rear property line. When a homeowner converts one of those garages into a second bath or guest suite, which is where a large share of our Mr-Glass shower and mirror work lands, the enclosure can’t be ordered until the legal footprint is settled. Building and Safety plan review in Montclair requires that any habitable addition respect current setback lines, and a garage that is two feet off the rear fence cannot simply become living space without a survey and often a lot-line adjustment. We have opened up converted-garage baths where the framed shower wall had settled against the original garage slab and a stock Mr-Glass frameless kit would not hang true. The sequencing matters: survey and permit first, then curb and blocking correction, then template the glass. If you try to order the glass first, you will pay for a panel that does not fit. In a 1960s single-story stucco home near the Montclair civic center, we re-templated exactly such an opening, corrected the curb, and set a custom-cut Mr-Glass hinge door with new stainless hardware. It swings clean now, no shims showing.

Mr-Glass Models & Products We Service in Montclair

We install and service the full Mr-Glass residential line as it appears in Montclair homes: custom-templated frameless shower enclosures, both hinged and slider; semi-frameless sliding shower doors for tub-shower alcoves; mirrored closet doors and vanity mirror packages; and tempered window and patio-door glazing units for remodel replacements. On the parts side, we match OEM Mr-Glass hardware and glass specs where they still fit the opening. Where an original roller, sweep, or seal has been discontinued or was undersized from the start, we use quality aftermarket equivalents that hold up better in Montclair’s hard water.

FAQs – Mr-Glass Construction in Montclair

Can a Mr-Glass frameless shower enclosure be installed in a Montclair garage-conversion bathroom?

Yes, but only after the setback and survey question is settled. Montclair plan review requires a converted garage to meet current setback lines before it becomes habitable space, and in the 91763 core, many original detached garages sit within inches of the rear property line. We sequence the work that way: survey and permit confirmation first, then curb and blocking correction, then template and set the Mr-Glass panel. The glass cannot be ordered until the legal footprint is locked. Call (844) 384-3361 and we’ll explain what your specific lot will require.

Why does my Mr-Glass shower door bind or drag on the bottom in these older Montclair tract homes?

Because the original framed walls from the 1950s through 1970s were rarely square, and decades of stucco movement make them less square. A frameless panel mounted on an out-of-square alcove will bind at the sweep and creep out of hinge alignment. The fix is to re-template the opening, correct the curb and blocking, and reset the glass. Replacing the sweep without addressing the framing only lasts until the next seasonal shift.

Do the hard-water conditions in Montclair shorten the life of Mr-Glass shower glass and hardware?

Hard water etches glass and corrodes rollers and tracks faster in Montclair than in softer-water parts of the region. We see flat-spotted rollers and corroded tracks on shower doors that are only a few years old. The best defense is regular cleaning of the track and rollers, plus switching to stainless or quality aftermarket hardware when the original builder-grade parts wear out. We stock those parts for quick turnaround. For a quote on hardware replacement, call (844) 384-3361.

Will replacing a tub with a Mr-Glass walk-in shower require new permits in Montclair?

Yes, when the drain location moves, the shower valve is repositioned, or waterproofing is altered behind the wall. A straight tub-to-shower conversion in a Montclair tract home almost always touches plumbing and often exposes old galvanized lines and outdated electrical panels that must come up to current code. We pull the permits on every project where they’re required, and the work is inspected to close out legally. Call (844) 384-3361 for a free estimate that includes the permit scope.

Are you an authorized Mr-Glass dealer, and does that affect my warranty?

We are an independent construction and glass contractor, not an authorized or manufacturer-affiliated Mr-Glass dealer. That means we can tell you plainly whether a repair, a re-hang, or a replacement is the right call without pushing a product line. For warranty work, the manufacturer’s warranty terms apply to the product itself; our installation work is covered by our own workmanship warranty. If you have a specific warranty question, call (844) 384-3361 and we’ll walk through it.
