Mr-Glass Construction in San Bernardino, CA | Square One Builders
We provide independent Mr-Glass construction service across San Bernardino, from the 1950s tract homes in 92410 to the foothill subdivisions climbing toward the San Bernardino Mountains, including Highland Mr-Glass service areas. What makes our Mr-Glass work different here is simple: we know that a sagging shower door in San Bernardino is almost never just a hardware problem. It’s usually hard water corrosion on the rollers, UV-baked gaskets, or the original waterproofing finally giving out behind a wall that was tiled before anyone used waterproofing membrane. We diagnose the real cause and fix it honestly. Call (877) 688-9930 for a free estimate.
Why San Bernardino Residents Choose Us for Mr-Glass Service
We handle Mr-Glass doors and enclosures week in and week out, so the failures don’t surprise us anymore. Hard San Bernardino water eats pivot hardware. The summer heat, which pushes past 100°F for weeks at a stretch, bakes silicone seals until they crack. Santa Ana wind loading shakes west-facing walls and works aluminum frames loose over time. None of that fazes us.
Brent Calloway, Owner & General Contractor at Square One Builders, has spent nearly three decades working on homes throughout Southern California, and he approaches every Mr-Glass job the same way: open the wall, find what’s actually wrong, then set the glass on a surface that will hold. We stock the OEM Mr-Glass hardware and gaskets that match the original track and pivot geometry, and we keep quality aftermarket rollers and seals on hand for models where OEM parts are discontinued. If the frame is sound, we repair and re-seal. If it’s not, we tell you straight. No authorization or warranty implied, ever.

Common Mr-Glass Construction Problems We Solve in San Bernardino
- Sagging doors and threshold leaks. Pivot and roller hardware on Mr-Glass shower doors corrodes or seizes from hard San Bernardino water and repeated 100°F+ heat cycles. The door sags, the magnetic catch stops lining up, and water starts pooling at the threshold. We replace the worn hardware and re-square the door so it closes true.
- Cracked and dry silicone and gaskets. Factory silicone and gaskets on Mr-Glass enclosures dry out and crack under UV exposure and dry summer air, letting water wick past the curb. We see this constantly in the 1950s – 70s flatland bathrooms in 92404, 92410, and 92411, where the original bathroom construction was never designed for modern shower volumes.
- Chalked and discolored frames. Aluminum and vinyl frame profiles chalk, discolor, and lose coating adhesion after years of intense sun, especially on west-facing walls. It’s cosmetic at first, but once the coating fails, the aluminum underneath starts oxidizing. We can re-coat or replace the frame depending on how far it’s gone.
- Stress cracks from out-of-square openings. Older tract homes in San Bernardino rarely have square rough openings anymore. The house settles, the walls move, and the Mr-Glass panel gets torqued. You see stress cracks in the glass and misaligned tracks that leak at the bottom rail. We re-shim, re-square, and reset the panel before installing new glass.
- Hidden substrate rot behind the enclosure. This is the expensive one. Pre-1990s flatland bathrooms in 92410 and 92411 were often framed and tiled before current waterproofing standards existed, so water that gets past an old Mr-Glass seal doesn’t have a membrane to stop it. The framing behind the tile rots. We find it all the time.
Mr-Glass Service in San Bernardino: What Local Conditions Mean for Your Equipment
Because San Bernardino’s older flatland bathrooms in 92410 and 92411 were framed and tiled before current waterproofing standards, we always open the wall behind a Mr-Glass enclosure before setting new glass. Substrate rot and original plumbing are frequently hiding there. We’ve learned this the hard way. On a 1950s tract home near 92410, our crew pulled a sagging Mr-Glass aluminum shower enclosure and found the curb had never been properly waterproofed, so the framing behind it was soft—similar to what we watch for during Mr-Glass repair in Muscoy. We rebuilt the shower pan and tile, reset new OEM-track Mr-Glass panels on a squared curb, and the door now closes true with no threshold leak. That’s the difference between a glass installer who shows up with a drill and a general contractor who knows what’s behind the tile. If we set new Mr-Glass on a compromised curb, we’d be back in six months. We’re not interested in that.
Mr-Glass Models & Products We Service in San Bernardino
We work on the full Mr-Glass range you find in San Bernardino homes. That includes the aluminum framed shower enclosures with tempered glass doors, semi-frameless and frameless sliding shower door systems, vinyl-framed low-maintenance shower and tub surrounds, and the mirror and glass panel shower kits used in remodel conversions. Our approach is always OEM-first: when Mr-Glass hardware and gaskets are still available, we use them so replacements match the original track and pivot geometry. When OEM is discontinued, we move to quality aftermarket rollers and seals. You’ll know which one you’re getting before we start, and it’ll be on the written estimate. We also handle Mr-Glass sales & service for new installs and full bathroom remodels.

FAQs – Mr-Glass Construction in San Bernardino
Most sagging Mr-Glass doors are repairable. The problem is almost always corroded pivot hardware or worn rollers, not the glass itself. We replace the OEM Mr-Glass hardware, re-square the door, and re-seal the threshold. If the frame is cracked or the curb underneath has rotted, replacement becomes the better spend. Call (877) 688-9930 and we’ll give you a straight answer after seeing it.
No. We’re an independent general contractor that installs and services Mr-Glass products every week. That means we diagnose failures based on what we see in real San Bernardino homes, not a manufacturer script. No authorization or warranty is implied. We use OEM Mr-Glass parts when available because they match the original geometry.
OEM-first. When Mr-Glass still makes the hardware, gaskets, and rollers for your enclosure, we use them so the replacement matches the original track and pivot geometry exactly. When OEM is discontinued, we use quality aftermarket rollers and seals chosen for San Bernardino’s hard water and high heat. We tell you which one applies before the estimate is final.
A simple hardware swap and re-seal is usually done in a single visit. A full shower enclosure replacement or tub-to-shower conversion takes longer, especially in older flatland bathrooms in 92410 or 92411 where we may need to rebuild the curb and waterproofing before setting new glass. We’ll give you a timeline with the estimate, and it’ll be honest. Call (877) 688-9930 to get yours.
We service the Mr-Glass aluminum framed shower enclosures, semi-frameless and frameless sliding shower door systems, vinyl-framed tub and shower surrounds, and mirror and glass panel shower kits.
