Mr-Glass Construction in Sunnyvale, CA | Viceroy Construction
We install and service Mr-Glass shower enclosures, glass railings, and mirror systems across Sunnyvale as your General Contractor in Sunnyvale, and the work here is shaped by one thing most glass contractors miss: post-and-beam Eichler walls that flex and drift out of plumb. We’re an independent Mr-Glass service provider, not manufacturer-authorized, so our recommendations follow what your opening actually needs. If you’re dealing with a Mr-Glass door that binds, drags, or jumps track in a Sunnyvale home, call (877) 358-6557 and we’ll tell you straight whether it’s a repair or a replacement.
Why Sunnyvale Residents Choose Us for Mr-Glass Service
We’ve installed and serviced Mr-Glass frameless enclosures, bypass doors, and mirrored panels in Sunnyvale’s Eichler ranches and the newer townhomes along El Camino Real long enough to know how the brand’s hardware ages in this specific housing stock. Neil Drummond, who leads Viceroy Construction, trained in the building trades program at West Valley College and grew up in the Saratoga foothills near Mr-Glass in Cupertino. He’s spent nearly three decades working South Bay homes, and that experience matters when a Mr-Glass top rail has walked out of alignment on a wall that’s moved an eighth of an inch since 1962.
We stock Mr-Glass OEM hinges, rollers, sweeps, and seals locally so Sunnyvale turnaround is measured in days, not weeks. And when a discontinued Mr-Glass series needs parts, we match quality aftermarket hardware rather than leaving you with a door that never closes right. Our repair-first stance is simple: if the glass and frame are sound, we fix it. If every hinge is failing and the opening can’t be re-squared without tearing out tile, we’ll tell you that too.

Common Mr-Glass Construction Problems We Solve in Sunnyvale
These are the failure patterns we see repeatedly in Sunnyvale homes, and they trace back to the construction methods and climate here, not to any defect in the Mr-Glass product itself.
- Doors that bind and sweeps that gap on out-of-plumb walls. Sunnyvale’s original Eichlers and 1950s – 60s tract ranches were framed with post-and-beam construction that flexes over time. By the time we template a frameless Mr-Glass enclosure, the wall is often out of plumb by a half-inch or more. A door templated to that wall binds within a season unless the opening is shimmed and re-squared first.
- Bypass doors jumping track or dragging on flexing walls. Mr-Glass bypass top rails and roller hardware sit on walls that move more than modern stud framing. In Sunnyvale ranches, that movement walks rollers out of alignment. The door drags, then jumps track. Re-tightening without re-squaring is a temporary fix.
- Clouded low-iron glass from dry-season smoke and hard water. Sunnyvale’s dry summers bring wildfire smoke and dust that settles on exposed frameless panels. Left unsealed, that film etches into mineral spotting and the low-iron clarity fades. We see this on unsealed Mr-Glass panels throughout ZIPs 94086 and 94087.
- Hinge anchors pulling out of original bathroom framing. Those 1950s and 60s bathrooms rarely have solid blocking behind tile at Mr-Glass hinge points. Heavy 1/2″ tempered glass puts real load on hinges, and without blocking, the anchors pull and crack the tile over time.
- Walk-in conversions on shallow slabs with aging drain lines. Converting a Mr-Glass tub to a walk-in shower on a Sunnyvale slab means working with sub-slab drain lines that are decades old. We scope the line condition before the glass goes in, because glass enclosures are the last thing installed, not the first.
Mr-Glass Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Here’s the Sunnyvale-specific reality that changes how Mr-Glass work has to be done. Because the city’s post-and-beam Eichler roofs have no attic depth and rely on exposed beams, any opening we template for a glass enclosure or railing must be verified against a wall that moves with the beam structure. Sunnyvale inspectors expect engineered documentation for anything that ties into those roof lines, which is why we measure twice and photograph the wall condition before ordering glass. It’s also why we check what’s behind the tile at every hinge point before a panel goes up. Contractors crossing over from San Jose or Mr-Glass in Santa Clara routinely underestimate this, and the result is a Mr-Glass enclosure that looks fine for six months and then starts binding. That’s the difference between templating glass for a wall and templating it for a wall that moves.
On an orchard-era Eichler off South Mathilda Avenue near Mr-Glass in Mountain View in ZIP 94086, our crew tore out a 1990s framed Mr-Glass bypass unit whose rollers had jumped track for years on a post-and-beam wall that was out of plumb by three-quarters of an inch. We re-squared the opening, added solid blocking behind the tile, and installed a 1/2″ frameless Mr-Glass enclosure with OEM hinges. The door now swings clean and the sweep seals tight. The homeowners also had us mirror the adjacent wall, which we set plumb against the beam line so it wouldn’t show a visible wedge. The details you don’t see are the ones that matter most.
Mr-Glass Models & Products We Service in Sunnyvale
Our crews work on the full Mr-Glass residential line: frameless heavy-glass shower enclosures in 3/8″ and 1/2″ tempered, semi-frameless and framed sliding/bypass tub and shower doors, mirror closet doors and custom mirrored wall panels, and interior glass railing and panel systems. For enclosures that are still serviceable, we install Mr-Glass OEM hinges, rollers, sweeps, and seals, and we keep the most common hardware stocked for fast Sunnyvale turnaround. Discontinued series get matched aftermarket hardware only where OEM is no longer available. This same vendor-depth thinking runs through our broader Mr-Glass sales & service work across the South Bay.

AfterMr-Glass Service Pricing in Sunnyvale

Re-squaring an out-of-plumb post-and-beam opening, blocking hinge points, and scoping sub-slab drains add labor that a generic glass outfit never quotes. Our estimates are written, line-item, and free. Here’s what fair market pricing looks like for Mr-Glass work in Sunnyvale:
| Mr-Glass Service | Typical Sunnyvale Range |
|---|---|
| Frameless Glass Shower Enclosure | $4,500 – $12,000 |

FAQs – Mr-Glass Construction in Sunnyvale
Yes, but only if the opening is re-squared and shimmed before templating. We’ve installed frameless Mr-Glass enclosures on post-and-beam walls that were three-quarters of an inch out of plumb by adding solid blocking and correcting the wall line first. Skipping that step is how doors bind within a season. Call (877) 358-6557 and we’ll assess your specific wall.
If the glass and frame are sound and the wall can be re-squared without tearing out tile, repair makes sense. We replace rollers, re-align the top rail, and shim the opening. If hardware is failing at every point and the opening geometry can’t be corrected without tile removal, replacement is the honest call. Call (877) 358-6557 and we’ll give you both numbers.
Yes, Sunnyvale’s planning and building review requires permits for shower conversions that touch plumbing, drain lines, or waterproofing behind the walls. Glass enclosure work alone typically doesn’t need a permit, but walk-in conversions do. We pull the permits and the inspections pass before the glass goes in.
Seal the glass after installation and wipe down panels during heavy smoke periods. Sunnyvale’s dry-season smoke and dust film etches into hard-water spotting on unsealed frameless panels. We apply a sealing treatment as part of every frameless Mr-Glass install and recommend a simple maintenance schedule for local water conditions.
Yes. Second-story additions on small Sunnyvale lots are a regular part of our work, and glass railings and mirrored panels tie into post-and-beam framing that needs engineered attachment points. We photograph and document the wall conditions before ordering any Mr-Glass glass, then install to the engineering that Sunnyvale inspectors expect.
