Mr-Glass Construction in Sunnyvale, CA | Toolbox Contractors
We provide independent Home Remodeling in Sunnyvale with Mr-Glass sales & service, handling frameless shower enclosures, tub-to-shower conversions, and custom vanity mirrors on homes from the 94086 Eichler tracts to the 94089 condos near the 237 corridor. What makes our Mr-Glass work different here is that we template glass against as-built surfaces, not original drawings, because Sunnyvale’s inspection process means walls and curbs rarely match the plan by the time final glass goes in. Norm Castellano leads the crew, and he’ll tell you straight what your enclosure actually needs. Call (855) 382-3257 for a free estimate.
Why Sunnyvale Residents Choose Us for Mr-Glass Service
We’ve hung Mr-Glass frameless doors in more Sunnyvale homes than we can count, from 1950s single-story ranches in 94087 to the 1970s condo stacks off Mathilda and Fair Oaks. We read Mr-Glass specifications directly, use OEM hinges, pivots, sweeps, and seals, and we know how their 3/8″ and 1/2″ tempered panels behave when a slab floor has settled half an inch since 1962. We’re an independent General Contractor in Sunnyvale, not a manufacturer shop, so we’ll tell you when a panel is worth saving and when replacement is the only honest call. Norm Castellano grew up around houses that were always mid-project, and he runs this crew with the same eye: measure twice, hang once, and never let a homeowner pay for work that doesn’t need doing. Tell me what you’ve got and I’ll tell you what it actually needs.
We carry the Mr-Glass lines that matter for Sunnyvale’s housing stock: Mr-Glass sales & service covers the full catalog, but locally we stock the frameless pivot doors, neo-angle corner enclosures, and sliding bypass kits that fit the tight baths and low-threshold layouts common across this city. Our Sunnyvale service area spans all four ZIP codes, and we schedule around the wet season so your bathroom isn’t torn apart during the November-to-March stretch when other trades are racing to beat the rain.

Common Mr-Glass Construction Problems We Solve in Sunnyvale
These are the failure patterns we walk into most often in Sunnyvale, each one tied to how houses here were built and how they’ve aged:
- Pivot loosening and edge chipping on frameless doors. Sunnyvale’s slab-on-grade ranches settle, especially after a kitchen or bath remodel pulls load off one wall and onto another. The door loses alignment, the pivot binds, and the glass edge starts to chip. We re-set the pivot with OEM hardware and only re-drill if the original hole geometry is intact.
- Hinge and bracket corrosion in 101/237 corridor condos. Those 1970s-80s units often have undersized original bath fans, so moisture hangs in the room after every shower. Mr-Glass hardware is built to tolerate humidity, but not standing condensation. We replace corroded brackets and recommend ventilation upgrades before re-hanging the enclosure.
- Seal and sweep failure on sliding bypass kits. The Eichler-influenced tracts are full of low-threshold and curbless layouts. When the sweep on a bypass door hardens or tears, water tracks across the floor every morning. We stock Mr-Glass OEM sweeps and seals so the fix is same-trip, not a two-week wait on a parts order.
- Mirror desilvering on wall-hung vanity mirrors. Remodel work changes humidity and wall conditions mid-project, especially if the bath goes from original drywall to tile with a new exhaust routing. The silvered backing on older Mr-Glass mirrors can fail at the edges. We template and install new Mr-Glass vanity glass to the exact opening.
- Out-of-plumb walls discovered before glass goes in. This is the big one in Sunnyvale. By the time final inspection clears, the wall the glass is supposed to hang on may be a quarter inch out of plumb. We laser-template every panel and adjust the curb or mounting plane before the Mr-Glass door ever leaves the truck.
Mr-Glass Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Sunnyvale’s plan review and inspections are famously thorough, and the city’s green-building and stormwater rules on remodels mean a frameless shower enclosure is frequently the last item to be templated. The final wall, tile, and drain geometry only clears inspection after other trades close out their work, so Mr-Glass measurements here regularly get taken against as-built surfaces, not the original drawings. In 94087, where Eichler-influenced ranches have settled for six decades and previous owners have tiled over old curbs, we routinely find the as-built wall is out of plumb by half an inch or more. That’s not a defect in the Mr-Glass product; it’s the reality of hanging precision glass on a sixty-year-old frame. We laser-template every panel, shim the curb level, and mount the pivot hardware so the door swings clean and seals tight. If you’re in the 94087 or 94086 tracts and need Mr-Glass in Santa Clara or Sunnyvale, we cover boths on your remodel has been quoted off the blueprints, push back. Glass measured from drawings never fits the way glass measured from the finished wall does.
Mr-Glass Models & Products We Service in Sunnyvale
We install and repair the full Mr-Glass product range relevant to Sunnyvale’s housing stock. That includes the Frameless Shower Enclosure systems in 3/8″ and 1/2″ tempered glass, both sliding and pivot configurations, the neo-angle and corner enclosures that fit the tight Eichler-era baths, and the sliding bypass and tub-shower kits common in 1970s-80s condos. We also fabricate and install Mr-Glass custom mirrors for vanity and vanity-wall applications. When a part fails, we reach for Mr-Glass OEM hinges, pivots, sweeps, and seals first, so the glass keeps its factory hole patterns and warranty geometry. We only substitute a quality aftermarket part when OEM is discontinued for older enclosures. If a panel is chipped at the edge or a pivot hole is compromised, we’ll tell you honestly that replacement beats re-drilling, because a weakened tempered panel is a safety issue, not a cosmetic one.

AfterMr-Glass Service Pricing in Sunnyvale
The cost of Mr-Glass work in Sunnyvale depends on the enclosure type, the glass thickness, and how much correction the surrounding structure needs before glass can be hung. Here are the ranges we quote most often in this market:
| Project Type | Typical Range |
|---|---|
| Frameless Glass Shower Enclosure (Walk-In Shower Installation) | $4,500 – $12,000 |

| Shower Replacement | $3,000 – $8,500 |
| Bathroom Vanity Installation | $800 – $3,000 |
What pushes a Sunnyvale project toward the higher end is structural correction: leveling a settled curb, shimming an out-of-plumb wall, or replacing subfloor that’s been wet too long. A free estimate with us includes laser measurements of the finished wall and a written line-item quote, so you know exactly what you’re paying for before any glass is ordered.

FAQs – Mr-Glass Construction in Sunnyvale
The most common cause in Sunnyvale is slab settlement, especially in the 1950s-60s ranch homes where the original concrete has shifted over decades. As the floor moves, the pivot loses alignment and the door drags on the threshold or fails to latch. We re-set the pivot and adjust the mounting plane, and in most cases the door swings like it did on day one. Call (855) 382-3257 for a free assessment.
No, and we won’t. Sunnyvale’s inspectors sign off on the finished wall, tile, and drain geometry first, and glass installed before that point usually has to come out. We template after inspection, measure the as-built surfaces with laser tools, and cut the Mr-Glass panels to fit what’s actually there.
Replace. A chip at the edge of a tempered panel weakens the whole sheet, and a compromised panel that shatters under a temperature swing or a thrown door is a hazard in a small condo bath. We’ll match the Mr-Glass bypass panel to the remaining door and hang it with new OEM seals and sweeps. Call (855) 382-3257 for a free measurement.
We do, and those conversions are some of our most common Mr-Glass in Cupertino and Sunnyvale projects. The challenge is that Eichler-influenced baths are tight and the original tub curbs are often tiled over, so we level the curb, re-frame the shower pan, and then template the frameless Mr-Glass panels against the corrected surface. Call (855) 382-3257 to talk through your bathroom layout, the estimate is free.
Frameless enclosure work typically falls between $4,500 and $12,000, tub-to-shower conversions between $3,500 and $10,000, and a vanity installation between $800 and $3,000. The spread depends on glass thickness, structural correction, and whether we’re working on a settled slab ranch or a 1970s condo. For a line-item quote on your specific project, call (855) 382-3257.
