Mr-Glass Construction in Mountain View, CA | Timberline Contractors
We provide independent Mr-Glass service across Mountain View, handling aluminum windows, sliding patio doors, frameless shower enclosures, and mirrored closet systems for homes throughout the 94039, 94040, 94041, and 94042 ZIP codes. The one thing that makes our Mr-Glass work different here is simple: we know what happens when mid-century construction meets modern glass. Slab-on-grade Eichlers, settled ranchers, and Bay fog all create specific failure patterns that out-of-town crews miss entirely.
Timberline Contractors is a licensed General Contractor in Mountain View, not a manufacturer-authorized shop. That independence matters. We recommend what’s right for the house, not what moves inventory. Nelson Fung, our owner, grew up steeped in hardware stalls and material selection, and he built this company around the idea that a window or shower door should outlast the contractor who installed it. Call us at (866) 253-5808 for a free estimate on any Mr-Glass repair or replacement in Mountain View.
Why Mountain View Residents Choose Us for Mr-Glass Service
Mr-Glass aluminum systems show up all over this city, especially in the post-war ranchers and Eichlers built between the 1940s and 1960s. Those original frames are still doing their job in a lot of homes, but they need a contractor who understands their quirks. Aluminum conducts cold, so frames sweat when Bay fog rolls in during summer mornings. Rollers flat-spot on settled slabs. Original glazing channels collect grime that most homeowners never see until a door starts dragging.
We’re the local crew that has pulled apart enough 4600 Series windows and 9700 Series patio doors to know exactly which parts fail first and why. Nelson Fung spent years swinging hammers on remodels and commercial builds before launching Timberline, and that hands-on experience shapes how we scope every Mr-Glass job in Mountain View. We don’t guess at a fix. We open it up, show you what’s actually failing, and give you an honest repair-or-replace recommendation with real numbers attached. Our clients also get access to Mr-Glass sales & service knowledge that spans the full product line.

Common Mr-Glass Construction Problems We Solve in Mountain View
- Condensation and mildew in 4600 Series aluminum window tracks. Mountain View’s fog intrusion from the Bay hits hardest along the bayside edge of the city, and older aluminum frames transmit that cold straight into the interior track. Moisture pools, black mildew forms, and the glazing gaskets degrade faster than they should. We clean, re-seal, and replace the damaged gaskets so the window drains properly again.
- Sliding patio doors that drag, hang, or pull out of plumb. The 9700 Series roller system was never designed for foundations that shift over six decades. Mountain View’s slab-on-grade ranchers settle, and when the slab moves, the door frame twists. Rollers flat-spot, the door scrapes the track, and eventually the lock stops aligning. We re-hang the door, replace the rollers with OEM parts where available, and re-seal the exterior flange against winter rain.
- Frameless shower glass that chips at the wall edge. In gut-renovated mid-century bathrooms, the original slab floor or tile curb was rarely dead level. When a new Mr-Glass 5000 or 6200 Series frameless panel goes in against an out-of-square opening, the glass edge catches on the adjacent wall and chips or fractures over time. We level the curb or adjust the hinge geometry before the panel goes in, so the glass clears every time.
- Water intrusion through aging glazing and weep paths. Mountain View’s wet winters concentrate rain from November through March, and failing seals behind exterior window flanges let water in. The original shallow roof overhangs on many post-war houses don’t help. Water that gets behind the flange wicks into dryrot in the framing. We pull the trim, inspect the sheathing, and replace the flashing and glazing so the opening stays dry.
- Mirrored closet door systems that jump their tracks. The original Mr-Glass mirrored wardrobe doors in Eichler-era homes often sit on hardware that was installed against walls that have since shifted out of square. Doors skip the track, bind on the pile, or the mirrors start to pull from their mounting clips. We replace the track hardware, re-square the opening, and re-secure the glass so the doors glide without resistance.
Mr-Glass Service in Mountain View: What Local Conditions Mean for Your Equipment
Here’s what generic Mr-Glass pages won’t tell you about Mountain View, and it’s the single most important check we make before cutting into a slab for any Mr-Glass shower or window installation. In the Eichler neighborhoods around Monta Loma and Stierlin Estates, the original radiant heating isn’t in the walls or ceilings. It’s copper tubing embedded directly in the concrete slab, installed back when these houses were built in the mid-century boom. Cut into that slab for a new Mr-Glass walk-in shower pan or threshold, and you rupture the heating loop. The entire system loses pressure, and suddenly a shower remodel becomes a whole-house heating retrofit.
We scope for this before we ever open a pan. Sometimes the loops can be isolated and abandoned without disturbing the rest of the system. Sometimes the homeowner decides a forced-air retrofit was overdue anyway. But the point is we check first, before the saw touches concrete. Out-of-town contractors don’t, and we’ve seen the aftermath. That checkable fact about Mountain View’s housing stock isn’t true in neighboring Sunnyvale or Mr-Glass repair in Los Altos to the same degree, and it changes how every slab-touching Mr-Glass job gets priced and planned.
Mr-Glass Models & Products We Service in Mountain View
Our crew works on the full Mr-Glass product range you’ll find in Mountain View homes. The 4600 Series aluminum replacement windows, still common in original mid-century ranchers. The 9700 Series sliding glass patio doors, which show up in Eichler living rooms and ranch family rooms. The 5000 and 6200 Series frameless sliding shower door systems that come standard in many gut-renovated bathrooms. And the mirrored closet door systems that line the bedroom halls of post-war homes throughout the 94040 and 94041 ZIP codes.
Where the Mr-Glass series is still supported, we order genuine OEM rollers, track, and glazing gaskets so the repair matches factory spec. Where support has dried up, we source quality aftermarket hardware that meets or exceeds the original tolerances. We stock the most common rollers, gaskets, and hardware locally so Mountain View service calls don’t stall waiting on parts from a distributor three states away.

FAQs – Mr-Glass Construction in Mountain View
Will cutting into the slab for a Mr-Glass walk-in shower break our home’s radiant heat?
It can, yes. In Mountain View’s Eichler homes around Monta Loma and Stierlin Estates, original radiant heating runs as copper tubing embedded in the concrete slab. Cutting into that slab for a shower pan or threshold can rupture the loop. We scope for loop location before any cut, and where possible we isolate and abandon only the section in the work area. Call (866) 253-5808 for a slab check before you plan a Home Remodeling in Mountain View.
Why do our Mr-Glass sliding patio door rollers keep wearing out in Mountain View?
Most of the time, it’s not the roller itself. It’s the slab. Mountain View’s post-war ranchers and Eichlers sit on concrete slabs that settle over decades, and when the slab shifts, the door frame goes slightly out of square. That misalignment concentrates load on one roller until it flat-spots. We fix the underlying geometry, not just the part, so replacements don’t fail in another year.
Can you match a replacement Mr-Glass window or shower door to our mid-century Eichler?
Yes. We match the frame dimensions, glazing style, and hardware profile to what the house originally had. For Eichler-era openings, that often means working with narrow stile frames and specific glazing bead profiles that big-box replacements can’t replicate. We measure on-site and quote against the existing conditions, not a catalog guess.
Our Mr-Glass shower glass chipped at the wall – can it be saved?
Depends where the chip is and how deep it goes. Edge chips at the hinge side are sometimes repairable with polishing if the glass is thick enough. Chips that radiate into the panel face usually mean replacement. We’ll inspect the panel and give you a straight answer on whether repair is safe or replacement is the only option before you spend anything. Estimates are free at (866) 253-5808.
Do you follow Mountain View permitting rules for Mr-Glass window and shower work?
Yes. We pull permits wherever Mountain View requires them, which typically covers window replacements that alter rough openings and any shower work that moves plumbing or structural walls. We handle the paperwork, schedule the inspections, and close out the permit fully before we consider the job done.
