Mr-Glass Construction in Rubidoux, CA | Timberline Contractors
We’re Timberline Contractors, an independent Mr-Glass service provider working across Rubidoux, and we handle everything from sagging frameless shower doors to full tub-to-shower conversions. What makes our Mr-Glass work different in Rubidoux is that we actually understand the county-island permitting, out-of-square mid-century walls, and inland heat that make these glass systems fail here in specific, predictable ways. We’re not a Mr-Glass authorized dealer or warranty center, we’re a licensed general contractor who repairs and installs Mr-Glass products the right way. Call (866) 253-5808 for a free estimate.
Why Rubidoux Residents Choose Us for Mr-Glass Service
Most of the Mr-Glass shower enclosures and glass panels we work on in Rubidoux were installed years ago, often in homes built before current framing standards, and we’ve handled similar Mr-Glass service in Grand Terrace. Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years swinging hammers on everything from Eastside bungalows to mid-size commercial builds before starting Timberline. When we look at a Mr-Glass door that’s drifting open or leaking at the curb, we’re not just replacing parts, we’re figuring out why the wall behind it moved. That matters in Rubidoux, where a lot of houses sit on compact lots with settled framing.
We use OEM Mr-Glass hinges, rollers, and seals whenever the enclosure is worth keeping, and we’re straightforward about when it isn’t. If the glass is chipped at an edge or the frame has gone out-of-square, we’ll tell you replacement beats chasing parts. No runaround, no padding the ticket. Do it right the first time or explain yourself twice.

Common Mr-Glass Construction Problems We Solve in Rubidoux
- Hinge and pivot hardware loosening on frameless doors. Older Rubidoux homes often have walls that have settled a few degrees out-of-square, which puts uneven weight on Mr-Glass frameless panels. The hinge screws tear loose from old tile or drywall, the door sags, and eventually it won’t close. We reframe the opening, reset the hinges, and square the panel so it works without binding.
- Factory sweep seals and bottom gaskets drying out and cracking. Rubidoux gets 100°F-plus summer days with hard water mineral buildup, and that combination bakes Mr-Glass seals until they split. Water leaks at the curb, stains the shower base, and slowly rots whatever’s underneath. New OEM seals, properly bedded, fix it for years.
- Tempered panel edge chips from tight-lot moving. A lot of Rubidoux’s mid-century homes have narrow doorways and halls from the Mission Boulevard corridor to the bluff side. When a Mr-Glass panel gets moved through those spaces during a remodel or staging, the edge takes a hit. A chipped tempered edge means the panel can’t be safely re-installed. We know how to stop that before it starts.
- Sliding bypass track rollers corroding and binding. Homes near the Santa Ana River corridor get humidity swings and seasonal drainage moisture that stock rollers don’t handle well. The rollers corrode, the door jumps track, and the track itself starts to bend. We replace worn Mr-Glass rollers and adjust the track alignment so the bypass door glides like it did new.
- Out-of-square tub-to-shower conversion framing. When a Mr-Glass semi-frameless kit goes into a Rubidoux tub alcove that’s not square, the glass panels sit cocked and the seals don’t make contact. We correct the substrate and flashing before the glass goes in, because the finish on top of a bad substrate is just a future callback.
Mr-Glass Service in Rubidoux: What Local Conditions Mean for Your Equipment
Here’s the thing most people don’t realize until a project stalls: much of Rubidoux’s buildable ground is unincorporated county island land, not City of Riverside jurisdiction. You can live on a street where half the block falls under Riverside County permitting and the other half under city rules. So a shower or glass panel swap that touches framing can land under county inspection timelines that owners assume are city-run, and a contractor who doesn’t check jurisdiction before opening walls gets surprises. We’ve lost count of the Rubidoux projects where a homeowner called us after a handyman tore into a shower wall and found out the permit was never pulled because the address was county, not city — the same issue we watch for during Mr-Glass repair in Highgrove. For Mr-Glass owners, that means even a “simple” tub-to-shower conversion or a reframe behind a sagging hinge can come with county requirements. We check the jurisdiction on every Rubidoux job before we bid, because it changes the schedule and sometimes the scope. If a framing repair stays inside the existing permit, fine. If not, we pull what’s needed and make sure it passes inspection the first time.
Mr-Glass Models & Products We Service in Rubidoux
We service the full Mr-Glass residential lineup: pivot and hinge frameless shower door systems, sliding bypass tub and shower enclosures, semi-frameless shower door kits, and custom-cut mirror and glass panel installs. On the parts side, we keep OEM Mr-Glass hinges, rollers, and seals stocked for the most common Rubidoux call types so we’re not ordering hardware from three states away and leaving your bathroom open for a week. When OEM parts are discontinued or cost more than the enclosure is worth, we use quality aftermarket hardware that matches the glass thickness and weight. We tell you which one we’re using and why, before we install it.

FAQs – Mr-Glass Construction in Rubidoux
Can you replace just the glass door on my Mr-Glass shower enclosure without redoing the whole shower? Yes, if the frame is square and the surrounding tile is solid. We’ll pull the old panel, measure for a new OEM or matched tempered panel, and reset it with fresh hinges and seals. If the frame has settled out-of-square, we’ll tell you before we order glass. Call (866) 253-5808 for a free measurement and quote.
Do I need a county permit for a tub-to-shower conversion in unincorporated Rubidoux? Often yes, because much of Rubidoux falls under Riverside County permitting, not City of Riverside rules. If the conversion touches plumbing or framing, county inspectors typically need to see it before the walls close. We check jurisdiction on every job and handle the permit if it’s required.
Why does my frameless Mr-Glass door keep drifting open or hitting the wall? The hinge or pivot hardware has loosened, usually because the wall behind it isn’t square anymore. In a lot of Rubidoux’s older homes, that’s a framing settlement issue combined with years of heat cycles. We reset the hinges, square the panel, and if the wall needs reframing, we do that first. A quick call to (866) 253-5808 gets you a straight answer on whether it’s a hinge fix or something bigger.
Does the inland heat and hard water in Rubidoux damage Mr-Glass seals and hardware? Absolutely. Rubidoux’s summer heat regularly runs past 100°F, and the local water is heavy with minerals. Together they dry out Mr-Glass sweep seals, corrode rollers, and leave white scale that eats at gaskets. We see it every season. The fix is OEM or matched replacement seals and hardware installed with the right clearances for heat expansion.
Will a new Mr-Glass enclosure fit through my older Rubidoux home’s narrow hallway and doorway? It can, but it needs to be staged carefully. Rubidoux’s mid-century homes and some manufactured units have doorways and hallways that were never designed for a full tempered glass panel. We measure the path in, not just the bathroom, and if the panel won’t clear, we’ll order it cut for safe staging. Call (866) 253-5808 and we’ll check the access first.
