Mr-Glass Construction in Portola Valley, CA | Timberline Contractors
We provide independent General Contractor in Portola Valley services for Mr-Glass framing, glass panel, and shower enclosure work, and the one thing that makes our work here different is that we plan every job around the town’s hillside access and fire-safety review process before we ever unload a panel. Whether it’s a hinged frameless door that’s dropped out of square or tempered glass chipped at the edge, we diagnose, source, and install for homes on steep lots, winding private roads, and multi-acre properties. Call Nelson Fung and the Timberline Contractors team at (866) 253-5808 for a straight answer and a free estimate.
Why Portola Valley Residents Choose Us for Mr-Glass Service
We’ve installed and serviced Mr-Glass frameless shower enclosures and glass systems across the Peninsula hills long enough to know how their hardware ages under real-world stress rather than showroom conditions. Hinges that seize, openings that rack slightly out of square, seals that fail behind tile. As an independent Mr-Glass service provider, we are not authorized, sponsored, or endorsed by Mr-Glass, which means we can tell you honestly when a part is worth the OEM price and when an aftermarket seal does the job just as well. Nelson Fung has spent years swinging hammers on everything from Eastside bungalow remodels to mid-size commercial builds, and he brings that same no-shortcuts instinct to every glass panel we set in Portola Valley. “Do it right the first time or explain yourself twice” is how we work, because a leaking shower enclosure on a hillside custom home is a problem you should not have to think about twice.

Common Mr-Glass Construction Problems We Solve in Portola Valley
- Hinge and pivot hardware loosening or seizing on frameless doors. Portola Valley homes sit on expansive clay and steep slopes, so seasonal ground movement racks enclosure openings slightly out of square. That stress lands first in the hinge and pivot assemblies. We realign openings, re-set hardware, and replace worn pivots before the glass edge starts taking the load.
- Tempered glass edge chipping and breakage risk on unlevel shower curbs. Many of the town’s custom homes were built from the 1950s through the 1990s, and older curbs are rarely dead level. When a Mr-Glass panel sits on an uneven curb, the edge chips. We inspect, square, and re-bed the curb, then set new tempered glass when chip damage has compromised the panel.
- Silicone and sweep-seal failure causing concealed leaks behind tile. Hot, dry summers mean shower enclosures get heavy use, and failed seals move water into places you cannot see. We strip failed silicone, replace sweeps, and inspect the substrate behind the tile for water damage before re-sealing.
- Surface corrosion and pitting on hardware from aggressive well or softened water. Multi-acre Portola Valley properties often run on well water or heavily softened water, which eats at metal hardware faster than municipal supply. We identify the water chemistry issue, swap pitted hardware, and recommend finishes that hold up better.
- Sliding Mr-Glass shower door tracks binding on out-of-level floors. Older hillside homes settle over time, and a sliding door that once glided will eventually bind. We re-level the track, replace roller assemblies when worn, and confirm the glass runs true before we leave.
Mr-Glass Service in Portola Valley: What Local Conditions Mean for Your Equipment
Portola Valley’s very-high fire hazard severity zone means much of our glass and enclosure work sits inside remodels that also trigger fire department review and defensible-space rules, so a shower glass swap is often sequenced around inspections and fire-resistant material requirements that neighboring cities never impose. On a redwood-sided hillside home off a narrow winding private road, our crew replaced a failing Mr-Glass in Ladera style frameless shower enclosure whose pivot door had dropped and was chipping at the glass edge. After confirming truck access and staging glass panels up a steep driveway, we squared the curb, set new tempered panels, and installed fresh OEM-spec hinges and seals. A clean, leak-free enclosure that passed the remodel inspection. That is the part a generic glass company never accounts for: in Portola Valley, permits and fire review can add weeks to a simple bathroom project, and material deliveries need to be staged before the driveway gets tight. We plan for the review, the access, and the inspection from the first site visit.
Mr-Glass Models & Products We Service in Portola Valley
We service Mr-Glass in Stanford style Frameless Shower Enclosure systems in hinged and pivot door configurations, the Mr-Glass Sliding Shower Door series, custom-cut tempered glass panels and fixed sidelights, and Mr-Glass Neo-Angle and corner shower enclosures. For fast turnaround in Portola Valley, we stock common sweep seals, hinge bushings, and roller assemblies. When a matching Mr-Glass hinge or pivot assembly matters for fit and safety, we source the OEM hardware. When an OEM part is discontinued or overpriced, we use quality aftermarket glass and seals and tell you exactly what we are doing and why. When hardware or seals are still sound, we reseat and realign rather than push a full replacement. When glass is chipped at the edge or the opening is badly out of square, honest replacement is the safer call, and we will say that plainly.

FAQs – Mr-Glass Construction in Portola Valley
Yes. We regularly work on Portola Valley homes with steep, winding driveways and narrow private roads. Before we schedule installation, we do a pre-job site visit to confirm truck access and staging. If the driveway will not take a full-sized truck, we stage panels and tools at the road and carry them in. Call (866) 253-5808 to set up a site visit and free estimate.
If the glass edge is chipped, the panel has already been compromised and replacement is the safer call. Dragging usually means the opening has racked out of square or the hinge has worn. We can square the curb and re-set hardware, but chipped tempered glass should not be re-used. Call (866) 253-5808 and we will assess it in person before recommending anything.
Yes. In Portola Valley, bathroom remodels that touch structure often trigger fire department review under the town’s WUI rules, and the glass work is sequenced around those inspections. That can add weeks to the timeline compared to a city like Los Altos or San Francisco. We plan the glass installation around the permit and inspection schedule so you are not paying crews to wait.
It should not, if we address the reason the seals failed in the first place. We strip the old silicone, check the curb for level, inspect the substrate behind the tile for moisture damage, and only then re-seal and re-set. When we skip that inspection, a reseal is temporary. Call (866) 253-5808 to schedule a look at the existing enclosure.
We source OEM Mr-Glass hardware when a matching hinge, pivot, or roller assembly matters for fit and safety. When an OEM part is discontinued or priced unreasonably, we use quality aftermarket glass and seals and tell you exactly what is going in and why. As an independent provider, we are not bound to a parts list, and that works in your favor.
