San Mateo Construction is an independent Mr-Glass service provider, not a manufacturer affiliate or authorized dealer. We carry OEM Mr-Glass hardware and have installed and repaired their Mr-Glass sales & service product lines throughout the Santa Cruz Mountains. Noel Carrington, our owner, grew up in San Mateo County and has spent three decades working residential and light commercial jobs here. He knows what Portola Valley’s building department asks for, because he’s sat through those reviews.

Why Portola Valley Residents Choose Us for Mr-Glass Service

Mr-Glass frameless enclosures and railing systems demand precise measurement and mounting. On a flat suburban lot, that’s straightforward. On a sloping Portola Valley hillside with seasonal ground movement, it’s a different trade. We’ve learned to check hinge alignment against actual slab conditions, not just the drawing. That’s the kind of thing you pick up after enough rebuilds off narrow private lanes with mature oaks in the way.

We’re a general contractor first. That means when your Mr-Glass shower enclosure ties into waterproofing, tile, framing, or a full bathroom remodel, we handle the whole scope under one contract. No finger-pointing between the glass sub and the GC, because we’re both. Our Portola Valley service area work includes walk-in showers, tub-to-shower conversions, and full bathroom renovations where the glass is just one piece of a larger job.

Common Mr-Glass Construction Problems We Solve in Portola Valley

• Hinge sag and glass misalignment on hillside lots. Frameless enclosures rely on precise hinge geometry. When a hillside foundation shifts even a quarter inch through wet winters and dry summers, doors start to drag or gap. We re-align with adjustable OEM hinges and re-shim mounting points so the door swings clean.
• Hard water mineral etching. Many Portola Valley homes run on well water with high mineral content. That leaves a white film on glass that, over time, etches the surface permanently. We can polish light etching, but deeply etched panels usually need replacement. Ask us about sealant treatments that slow the buildup.
• Seal failure behind shower surrounds. Intense winter rains on sloped sites mean water finds its way behind poorly sealed glass channels. We replace failed seals with OEM Mr-Glass gaskets and verify the surrounding waterproofing before closing up the wall.
• Ember intrusion and smoke staining on exterior glass. In WUI zones, ember-resistant vents and fire-rated assemblies matter. Exterior glass railings and doors need proper clearance and sealing. We inspect for gaps that could let embers in during Diablo wind events.
• Cracked or chipped glass edges. On narrow private lanes with tight staging, panels get bumped during transport or install. A chipped edge will eventually run. We replace damaged panels and inspect the remaining glass for stress fractures.

Mr-Glass Service in Portola Valley: What Local Conditions Mean for Your Equipment

Here’s the thing people miss: Portola Valley sits almost entirely inside mapped wildland-urban interface with steep, wooded lots. That changes even interior glass work. The town’s planning and building review often requires tempered glass with enhanced ember-resistant framing for exterior assemblies and, in some cases, even interior openings that face wildfire exposure. A glass railing that passes code in San Carlos won’t necessarily pass here. We’ve pulled WUI-compliant assemblies through Portola Valley’s review process enough times to know what the inspectors look for, which means fewer surprise corrections on your project. If you’re off Old Spanish Trail or any of the narrow lanes winding up toward the hills, access itself becomes part of the job. Full-size trucks can’t always reach the door. We stage panels at the road and carry them in when we have to.

Mr-Glass Models & Products We Service in Portola Valley

We install and repair the full Mr-Glass residential line: Frameless Glass Shower Enclosures, Sliding Shower Doors, Custom Mirrors, and Glass Railing Systems. We use OEM Mr-Glass hardware for hinges, seals, and handles when it’s available, because fit and warranty compliance matter. When OEM parts are discontinued or lead times stretch into weeks, we’re straightforward about aftermarket options that match the original spec. If your glass is sound, we replace hardware and seals. If it’s chipped, cracked, or etched beyond polishing, we’ll tell you and quote full replacement. We stock common hinge sets, seals, and mounting hardware locally so Portola Valley jobs don’t stall waiting on a backorder.
