Mr-Glass Construction in Portola Valley, CA | Framework Contractors
We provide independent Mr-Glass service across Portola Valley, from frameless shower enclosures to sliding glass door systems and mirror wall panels. What makes our Mr-Glass work different here comes down to one thing: we understand how Portola Valley’s private-well water chemistry and clay-soil hillside movement stress these enclosures in ways you won’t see in neighboring towns. If your Mr-Glass shower door sags, leaks, or has clouded glass, call (844) 681-3590 for a free estimate from a crew that works on these systems every week.
Why Portola Valley Residents Choose Us for Mr-Glass Service
We’ve built our Mr-Glass service around the specific ways these units fail on hillside properties. Frameless 10mm enclosures, semi-frameless pivot doors, sliding systems with aluminum top rails, mirror and glass wall panels: we know the hinge sets, sweeps, and rail profiles on each configuration, and we stock OEM parts for the model lines still in production. That means faster turnaround and a repair that matches the original fit.
Noel Carbajal, our owner, grew up learning construction hands-on and spent three decades remodeling homes across hillside and canyon terrain before building Framework Contractors. That background shapes how we approach Mr-Glass work in Portola Valley: we expect the unexpected, check the opening before we quote, and won’t sell you a replacement when a re-hang and re-seal will do the job. We’re not authorized by Mr-Glass. We’re an independent contractor, and our first loyalty is to the homeowner paying the invoice.

Common Mr-Glass Construction Problems We Solve in Portola Valley
- Hinge sag and pivot drift on frameless 10mm enclosures. Portola Valley sits on expansive clay soils that swell in the rainy season and shrink through dry summers. When the slab under your shower shifts even a quarter inch, the fixed panel and door rack out of square, and the hinges start carrying weight they were never designed to hold. We re-shim, re-plumb, and replace the worn hinge set.
- Hard-water etching and mineral clouding on semi-frameless glass. Most Portola Valley homes run on private wells, not treated municipal water. The mineral load in that water, heavy with calcium and magnesium, etches glass faster than anything you’ll see in Menlo Park or Redwood City. We polish out light clouding and, where the etching is deep, recommend replacement glass with a protective treatment.
- Seal and sweep failure at the bottom rail on sliding Mr-Glass doors. When the bottom sweep wears or tears, water tracks onto the tile and works its way into the subfloor. On older Portola Valley bathrooms that lack a proper curb or pan slope, this is the most common source of rot and water damage we find behind the drywall.
- Corrosion and pitting of aluminum top rails and hinge hardware. Winter moisture, combined with tannin staining from the redwoods and oaks that canopy so many Portola Valley parcels, eats at raw aluminum and plated hardware. We see pitting and white corrosion powder on hardware exposed to shaded, damp bathroom air.
- Out-of-plumb shower openings on remodeled hillside builds. Portola Valley remodels often slice into existing slabs or add on to structures that have moved over decades. The rough opening isn’t square, and a standard enclosure kit won’t fit without shimming, custom cut panels, or a re-framed curb. We measure, adjust, and build the enclosure to the real opening, not the drawing.
Mr-Glass Service in Portola Valley: What Local Conditions Mean for Your Equipment
Here’s the thing most contractors outside the 94028 ZIP code don’t grasp: the water and the dirt are not the same as the rest of the Peninsula. Portola Valley’s parcels run on private wells and on-site septic rather than municipal water and sewer, and that well water carries a mineral load that etches and clouds frameless Mr-Glass panels measurably faster than the treated water in neighboring towns. We’ve pulled enclosures in Portola Valley that looked ten years older than identical units installed the same year in Atherton or Los Altos, simply because the water chemistry is different. That same mineral load is why we spec and seal glass differently on 94028 jobs: different edge treatments, different protective coatings on the interior face, and a different maintenance conversation with the homeowner about squeegeeing and drying after use. Add in the clay-soil movement that comes with steep, slide-prone hillside lots, and you have a set of conditions that directly maps to the failure modes we fix most often. If you live off Portola Road or up one of the private lanes near the Windy Hill side of town, your Mr-Glass enclosure is working harder than the same unit on flat ground in Woodside or Menlo Park.
Mr-Glass Models & Products We Service in Portola Valley
Our crew works on the full Mr-Glass product line you’re likely to have in a Portola Valley home. That includes the Mr-Glass Frameless Shower Enclosure in 10mm tempered hinged and sliding configurations, the Mr-Glass Semi-Frameless Pivot Shower Door series, the Mr-Glass Sliding Glass Shower Door systems with their aluminum top rail, and the Mr-Glass Mirror & Glass Wall Panel products for bathroom and vanity applications. When a unit is still in production, we fit OEM Mr-Glass hinges, sweeps, and rails so the original fit and warranty path stay intact. When a profile has been discontinued, we turn to quality aftermarket tempered glass and hardware matched to the existing thickness and edgework. We keep common hinge sets, sweeps, and rail profiles stocked for fast Portola Valley turnarounds, so you’re not waiting on a parts order from out of state.

What moves the price: whether we’re re-hanging an existing enclosure or installing new, the condition of the curb and pan, whether tile work is needed, and whether your home’s well water has already etched the glass past polishing. Our free estimate tells you exactly what we’d do and what it costs before you commit. Call (844) 681-3590 to schedule yours.
On a wooded multi-acre parcel off a private lane in Portola Valley, our crew pulled a sagging hinged Mr-Glass frameless enclosure where seasonal movement in the clay-soil slab had thrown the fixed panel out of plumb. We re-set and shimmed the unit to the true opening, swapped the worn hinge set and bottom sweep, and polished out the well-water mineral clouding on the 10mm glass. The homeowner got a tight, square enclosure back without replacing the whole door system.

FAQs – Mr-Glass Construction in Portola Valley
Yes, Portola Valley’s well water has a high mineral content that will etch and cloud glass panels faster than treated municipal water. The calcium and magnesium leave deposits that, once baked on, require polishing or replacement. We treat new installations with a protective seal and recommend a squeegee after each use. If your glass is already clouded, call (844) 681-3590 and we’ll tell you whether polishing or replacement is the better call.
In Portola Valley, the usual cause is clay-soil movement under the slab. Expansive soils swell in winter and shrink in summer, and even small shifts rack the shower opening out of square. The hinges then bind or sag. We re-plumb the panel, shim the opening, and replace the hinge set if it’s worn. Call (844) 681-3590 for a free estimate, we’ll measure and show you exactly what moved.
No. A shower enclosure is an interior finish, not part of the building envelope that Chapter 7A governs. WUI and Chapter 7A reviews apply to exterior assemblies: roofing, siding, windows, and doors. Your Mr-Glass shower install will not add to your plan review timeline, though if it’s part of a larger bathroom remodel that touches exterior walls, those exterior changes may trigger review separately.
Yes, if the glass is sound and the frame geometry is within tolerance. We replace hinges, sweeps, and rails when the unit is still in production, and source quality aftermarket parts when a profile is discontinued. On older enclosures we’ll tell you plainly when a re-hang and re-seal will hold versus when a full replacement is the cheaper long-run call. Call (844) 681-3590 and describe the problem; we’ll give you an honest read.
Yes. We’re a full-scope general contractor, so the shower pan, waterproofing, tile, curb, and glass all fall under one contract and one crew. That matters in Portola Valley bathrooms where the existing pan has failed or the curb isn’t sloped, common problems we find once the old enclosure comes out. We build the whole assembly to spec, then install the Mr-Glass enclosure over a pan we know is right. Call (844) 681-3590 to schedule a free estimate.
