Mr-Glass Construction in Los Altos, CA | Rowan Construction Group Mountain View
We provide independent Mr-Glass service across Los Altos for window replacement, frameless shower enclosures, and custom glass door systems. Our crew has learned one thing that makes our Mr-Glass work here different: Los Altos’s Heritage Tree Ordinance and adobe clay soils routinely force redesigns after original measurements, so we build re-measurement into every schedule rather than treating it as a surprise. Call (669) 215-4852 to schedule your free estimate.
Why Los Altos Residents Choose Us for Mr-Glass Service
We’ve installed and serviced Mr-Glass products in Los Altos since before the current teardown-rebuild boom took off. Grant Rowan, our owner, learned framing and finish work at Los Angeles Trade-Technical College before he ever collected a paycheck on a real job site. That background shows up in how our crew measures openings - we don’t trust the first number when the ground beneath it shifts seasonally.
Our Mr-Glass sales & service operation maintains install records for every unit we’ve touched in Los Altos. We know which Aluminum Series frames from the 1960s are still salvageable, which Vinyl Series gaskets fail first under south-facing exposure, and when a frameless shower panel needs custom re-cutting because the wall plane moved after final measurement. We stock OEM Mr-Glass hardware for common configurations and source verified aftermarket seals and rollers where OEM has discontinued the part. Under Clause 1 of the Haven Standard, every job starts with a written price and written scope - no exceptions, no “call for a quote.”
Our technicians are background-checked and uniformed. A live person answers our phones 24/7. Every visit produces a documented photo record, included as standard. That’s not marketing; it’s the discipline that has kept our projects within a few percent of the agreed price across 4,000-plus jobs since 2007.
Common Mr-Glass Construction Problems We Solve in Los Altos

- Aluminum frame corrosion and pitting. Original Mr-Glass Aluminum Series windows in Los Altos’s 1950s-70s ranch homes collect condensation at sill tracks for decades. The drainage holes clog. The frame pits from the inside out. We’ve replaced hundreds of these units; by the time the homeowner notices draftiness, the frame is often structurally compromised beyond gasket-level repair.
- Seal failure and fogging in dual-pane vinyl windows. Los Altos’s intense summer sun hits south and west exposures hard, then winter rains drive thermal cycling. The argon escapes, the desiccant saturates, and the glass fogs between panes. We can replace just the insulated glass unit on newer Vinyl Series windows, but repeated seal failure usually means the frame itself is torqued from foundation movement.
- Frameless shower enclosure hardware loosening and door sag. The adobe clay soils under Los Altos swell in winter rains and shrink in dry months. Wall planes shift. Hinge pivots that were plumb at install drift out of alignment. We’ve re-hung Mr-Glass frameless doors that were “fixed” twice before we arrived - the real problem was the substrate, not the hardware.
- Roller and track failure on sliding glass doors. High-use family room doors in Los Altos homes rack out of square when foundations move. The rollers flat-spot, the track grooves, and the door starts jumping its rail. We measure the opening squareness before quoting parts; a new roller set in a racked frame fails again in months.
- Custom mirror and glass door systems in new builds. Los Altos’s $3-million-lot teardown market demands precision. A glass door system measured before final framing often needs re-cutting after the drywall goes up tight. We don’t order final-cut glass until we’ve verified the opening ourselves.

AfterMr-Glass Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos sits on Santa Clara Valley adobe clay that swells and shrinks with seasonal moisture changes. That movement cracks foundations, racks window openings, and shifts wall planes - and it hits Mr-Glass products differently than it hits wood-framed competitors. A vinyl window frame flexes; an aluminum frame doesn’t, so the stress concentrates at corners and hardware points. We’ve seen Mr-Glass Aluminum Series frames shear their corner screws after three wet-dry cycles in a single Los Altos winter.
The Heritage Tree Ordinance adds another layer. Protected valley oaks on properties throughout Los Altos - including areas near University Avenue and the older ranch-home neighborhoods - trigger root-zone exclusion zones that can force foundation footprints to shift after original bids are set. On a teardown-rebuild off University Avenue, our crew installed Mr-Glass Vinyl Series windows and a Bathroom Remodeling - Los Altos frameless glass shower enclosure, but the heritage oak root-zone exclusion pushed the foundation wall four feet west, requiring a full re-order of three window units and a custom-cut shower panel. We coordinated the new glass order with the revised framing schedule, and the final install passed inspection without a single misfit unit. That’s the kind of redesign trigger that rarely appears in neighboring Mountain View or Sunnyvale, where tree protection rules are less restrictive and foundations more often land where first drawn.
Mr-Glass Models & Products We Service in Los Altos

We work on four Mr-Glass product lines common in Los Altos homes:
- Mr-Glass Aluminum Series sliding windows. Found in most 1950s-70s ranch homes here. We stock OEM sill tracks and replacement rollers; when frames are too corroded, we quote Vinyl Series upgrades with full written scope.
- Mr-Glass Vinyl Series double-hung and single-hung windows. Standard in Los Altos remodels and new builds since the 1990s. We carry insulated glass units, sash balances, and OEM weatherstripping for fast turnaround.
- Mr-Glass Frameless Glass Shower Enclosures. Popular in Los Altos’s luxury teardown market. We templated, fabricate, and install custom panels with OEM hardware; re-cuts are standard when foundation movement or plan revisions change the opening.
- Mr-Glass Custom Mirror & Glass Door Systems. Interior systems for closets, wine rooms, and entryways. We measure after final framing, not before - the only way to avoid gaps in a market where walls move.
We use OEM Mr-Glass hardware where available and verified aftermarket gaskets, rollers, and seals where OEM is discontinued or cost-prohibitive. If a window or enclosure shows structural frame damage or repeated seal failure after one repair, we recommend full replacement with a written quote before any work starts.
Mr-Glass Service Pricing in Los Altos
Our Los Altos service area pricing reflects the complexity of working in a high-value teardown market where plans change and precision matters. Here’s what Mr-Glass window and glass work runs:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
Cost drivers include the number of openings, whether the existing frames are square (many aren’t, in older Los Altos ranch homes), and whether Heritage Tree revisions require re-measurement and re-ordering for your Kitchen Remodeling - Los Altos project. Our quotes are flat prices with written scope - no change proceeds without a signed change order, which is why our projects finish within a few percent of the number we agreed to. We also offer a Free Second Opinion on any competitor’s written estimate; bring it in and we’ll review it line by line at no charge. Call (669) 215-4852 for your free estimate.

FAQs - Mr-Glass Construction in Los Altos
We can replace the insulated glass unit (IGU) alone on most Vinyl Series windows from the last 25 years if the frame is square and the hardware is functional. On Aluminum Series units with frame corrosion, or where the frame has racked from foundation movement, we recommend full replacement. Call (669) 215-4852 and we’ll assess which path makes sense for your specific units - estimates are free.
The adobe clay soils under Los Altos swell in winter and shrink in summer, shifting wall planes and door openings. Hinge pivots that were plumb at install drift out of alignment. We re-hang with structural backing verification and sometimes recommend hinge upgrades that tolerate more adjustment range. The real fix often involves addressing substrate movement, not just tightening hardware again.
Yes. Protected valley oaks and other heritage specimens trigger root-zone exclusion zones that can force foundation footprint shifts, which changes window and door placement weeks after original bids. We routinely re-measure and re-order Mr-Glass units after arborist-approved plan revisions - it’s built into our scheduling, not treated as an emergency.
Standard window replacement on a stable frame takes one to two days per opening once glass arrives. On Los Altos teardown-rebuilds, add one to three weeks for re-measurement and re-ordering if Heritage Tree revisions shift the foundation plan. We coordinate glass delivery with the revised framing schedule to avoid holding up other trades. Call (669) 215-4852 to discuss your project timeline - estimates are free.
Most 1960s-70s Aluminum Series units in Los Altos have reached end of useful life. The frames pit from condensation, the thermal performance is poor by current standards, and the single-pane or early dual-pane construction doesn’t meet modern energy code. We repair only where the homeowner specifically requests preservation; otherwise we quote Vinyl Series replacement with full written scope and a 365-Day Done Right Promise.
