We’ve installed and repaired Mr-Glass products in Sunnyvale since the brand gained traction with Peninsula homeowners in the early 2010s. Our crew knows the Serenity frameless series, the semi-frameless line, and the custom cabinet insert catalog well enough to spot installation errors that out-of-area crews miss. Sunnyvale’s water supply runs moderately hard at 120-180 ppm calcium carbonate, which accelerates corrosion on aluminum framing and degrades vinyl sweeps faster than in San Francisco’s softer municipal water. That matters because a Mr-Glass shower door installed without accounting for local water chemistry will show pitting within three to five years. We adjust our hardware specs and seal maintenance schedules accordingly.

We are not affiliated with or authorized by Mr-Glass. We are an independent service provider. That distinction matters because it means we work for the homeowner, not the manufacturer, and we source parts based on what fixes the problem rather than what fulfills a dealer obligation.

Why Trust Rowan Construction Group Sunnyvale for Your Mr-Glass Construction?

Grant Rowan grew up in Beverly Hills and picked up his first framing hammer before he could drive, trailing a family friend who remodeled homes in the flats off Wilshire. He trained in construction technology at Santa Monica College, where coursework covered structural load calculations, blueprint reading, and site safety - fundamentals he still references when scoping a job today. For more than two decades Grant and his crew have worked across Sunnyvale, including extensive remodel and build-out work in the Lakewood Village neighborhood near Washington Park, handling everything from permitted additions to full gut renovations and Kitchen Remodeling services.

That background shows up in how we handle Mr-Glass products. Frameless shower enclosures look simple - a few glass panels, minimal hardware - but the engineering is unforgiving. The glass is tempered, typically 3/8″ or 1/2″ thick, and the edges are polished or beveled depending on the series. Hinge placement must account for door weight, swing arc, and the fact that Sunnyvale’s older ranch homes often have walls that are not plumb. We’ve measured out-of-square openings in Birdland homes that were off by 3/4″ from top to bottom. A manufacturer-authorized installer working from a flat-wall template would have gaps, leaks, and eventual glass stress fractures. We measure each opening, order or cut glass to fit, and shim hinges to compensate.

Our technicians are background-checked and uniformed. A live person answers calls 24/7. Every visit produces a documented photo record - photos of the existing condition, the repair or installation process, and the finished work - that we deliver to the customer before we leave. Under Clause 1 of the Haven Standard, the written price comes before any work starts. Under the 365-Day Done Right Promise, if it is not done right, we make it right.

Common Mr-Glass Construction Problems We Fix in Sunnyvale

• Corrosion and pitting on aluminum framing from hard water and humidity. Sunnyvale’s water hardness leaves mineral deposits that etch anodized aluminum over time. The Serenity series uses 6463-T5 aluminum extrusions with a clear anodized finish; once pitting breaches that layer, the frame weakens and the finish cannot be restored. We see this most often in homes near the Lakewood Village area where original 1960s plumbing still feeds bathrooms. Replacement is usually the practical fix, though we can sometimes source matching trim to isolate the damage if the glass panels are intact.
• Hinge and pivot hardware failure - sagging or misaligned doors. Mr-Glass hinges use nylon bushings that compress and wear. In Sunnyvale’s dry summer heat, the bushings harden faster; in winter humidity, the screw pockets in glass can oxidize if water penetrates. A sagging door stresses the tempered glass at the hinge notch, which is the most common fracture point we encounter. We stock OEM Mr-Glass hinges and pivot sets, and we carry aftermarket upgrades with brass or stainless bushings for customers who want longer service life.
• Seal failure and water leakage from degraded vinyl sweeps or gaskets. The bottom sweep on a frameless door is a wear item. Sunnyvale’s hard water and occasional temperature swings - 90°F summer days dropping to 55°F nights - cause vinyl to lose elasticity faster than in coastal climates. A hardened sweep channels water outward instead of containing it. We replace with OEM Mr-Glass sweeps or equivalent Durometer 70A vinyl, and we check the threshold slope because many Sunnyvale slab floors settle slightly toward the drain over decades, changing how water collects.
• Glass panel shattering from improper installation or thermal stress. Tempered glass is strong but brittle at the edges. Frameless units need expansion clearance - typically 1/8″ to 3/16″ per panel - to accommodate thermal movement. We’ve found enclosures in Sunnyvale’s 1970s tract homes where the original installer wedged panels tight against tile, or used rigid silicone instead of neutral-cure sealant. The glass had no room to breathe. When thermal stress or minor foundation movement (common in Sunnyvale’s expansive clay soils) added load, the panel failed. We install with proper clearance and flexible sealants specified for the local climate range.
• Custom cabinet glass insert loosening or rattling. Mr-Glass cabinet inserts rely on silicone edge bonding or mechanical clips depending on the series. In Sunnyvale kitchens, the temperature cycling from oven use and the vibration from garbage disposals loosen clips over time. We’ve re-secured dozens of inserts in kitchen remodels along Washington Avenue and Morse Avenue, usually by upgrading to a two-part epoxy bond or adding concealed mechanical fasteners where the original design relied on adhesive alone.

Mr-Glass Parts & Our Repair-vs-Replace Approach

We stock genuine Mr-Glass replacement hardware at our Sunnyvale supply point: hinges, pivot sets, handles, towel bars, and the full range of vinyl sweeps and magnetic seals for the Serenity and semi-frameless lines. For glass, we source tempered panels from local fabricators who match Mr-Glass edge profiles and thickness specs; OEM glass is available for some current models but discontinued for older series, so we certify aftermarket panels to the same ANSI Z97.1 safety standard.

Our repair-vs-replace decision is straightforward. If the damage is isolated - a worn sweep, a loose hinge, a single scratched panel in a multi-panel enclosure - we fix it. If the aluminum frame shows extensive pitting, if multiple panels are cracked, or if the hardware mounting points in glass are stripped, replacement is more cost-effective than chasing parts for a compromised system. We explain this in the written estimate, with line-item pricing for both paths so the customer chooses with full information. Call (650) 405-3637 and we’ll walk through what’s actually needed.

Our Mr-Glass Service Process - Step by Step

1. 1
   Diagnosis with documentation. We inspect the Mr-Glass unit, photograph all condition issues, and identify the series and hardware generation. For shower enclosures, we check wall plumb, threshold level, and water drainage pattern - all factors that affect whether a repair will hold.
2. 2
   Written estimate before any work. The quote lists parts, labor, and any necessary adjustments (wall shimming, threshold re-slope, sealant type). No work proceeds until the customer approves in writing. Under the Haven Standard, Clause 1 is the whole point: the price is fixed before anyone picks up a tool.
3. 3
   Repair or installation with OEM-compatible parts. We use genuine Mr-Glass hardware where available, certified-equivalent aftermarket where not. For new installations, we verify glass tempering marks, check edge polish quality, and confirm hinge torque to manufacturer spec.
4. 4
   Testing and photo record delivery. We cycle the door through full open/close arcs, run water to verify containment, and deliver the documented photo record before leaving. The customer has evidence of what was found and what was done.
5. 5
   Warranty registration. Our workmanship warranty covers installation labor for one year. Parts carry the manufacturer’s warranty or our supplier’s equivalent. The 365-Day Done Right Promise applies if anything is not done right - we make it right.

Mr-Glass Products We Service & Install in Sunnyvale

We work with the full Mr-Glass residential line: Serenity frameless shower enclosures in standard and custom sizes; semi-frameless shower doors with matching panels and return walls; custom glass cabinet doors and inserts for kitchen and bath vanities; and mirrored installations including framed, frameless, and beveled-edge medicine cabinet assemblies. For Sunnyvale’s teardown-rebuild market, we spec Mr-Glass enclosures into new custom bathrooms regularly, and for the ADU boom along streets like Olive Avenue and Pastoria Avenue, we install compact Serenity units where space is tight and light transmission matters, drawing on our Mountain View Mr Glass service experience. We keep common Serenity hardware in stock for same-day repairs.

We Also Service These Brands

Rowan Construction Group Sunnyvale is not a single-brand shop. We install and repair KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Toto fixtures - fifty-plus vetted brands across seven trades. That sourcing depth means our written quotes use honest numbers rather than inflated single-source pricing, and it means we can coordinate a full bathroom remodel with matching materials instead of piecing together incompatible orders, as we do with our Santa Clara Mr Glass service.

FAQs - Mr-Glass Construction Service in Sunnyvale

Can you replace just the glass panel on my Mr-Glass shower door?

Yes, if the hardware and frame are in good condition. We source tempered glass panels matched to your Serenity or semi-frameless series thickness and edge profile, then reinstall using your existing hinges and handles. If the hinge pockets in the old glass are stripped or the frame is corroded, we’ll flag that in the written estimate before ordering. Call (650) 405-3637 for an exact quote - estimates are free.

My Mr-Glass shower door is hard to open and close - what’s wrong?

Most often the pivot hinge bushings are worn or the door has sagged due to loose set screws. In Sunnyvale’s hard water, mineral buildup can also bind the hinge mechanism. We disassemble, clean, and replace worn parts with OEM Mr-Glass hardware or upgraded brass-bushing equivalents. The fix usually takes under two hours.

Do you install Mr-Glass shower enclosures in older Sunnyvale homes with uneven walls?

Yes, and we expect uneven walls. Many Sunnyvale ranch homes built in the 1960s and 1970s have walls out of plumb by 1/2″ or more. We measure each opening at multiple points, order glass cut to fit, and use adjustable hinges or custom shimming rather than forcing a standard panel into a non-standard opening. That’s the difference between an installation that lasts and one that leaks or cracks within a year.

How long does a typical Mr-Glass shower enclosure installation take?

A standard Serenity frameless enclosure in a prepared opening takes one to two days: half a day for measurement and final glass order confirmation, then installation once the custom-cut panels arrive (typically 5-7 business days for local fabrication). Complex layouts with multiple panels or custom etching add time. We give a firm schedule in the written estimate, not a range that shifts.

Is it worth repairing a corroded Mr-Glass frame or should I replace the whole unit?

If pitting is superficial and limited to cosmetic areas, we can sometimes treat and protect the frame. Once pitting penetrates the anodized layer and reaches bare aluminum, corrosion accelerates and structural integrity degrades. At that stage, replacement is more economical than repeated repairs. We photograph the damage and show you both options with prices before you decide.
