AfterMr-Glass Construction in San Jose, CA | Rowan Construction Group
We’re Rowan Construction Group, an independent Mr-Glass service provider working across San Jose since 2007. We fix, replace, and upgrade Mr-Glass windows, patio doors, and frameless shower enclosures in homes from Berryessa to Almaden Valley, and we also offer our Fence Installation in San Jose. What makes our work here different is that we pair Mr-Glass hardware knowledge with San Jose’s specific seismic and soil reality, so your glass survives both the dry-summer clay shift and the next quake. Call (470) 298-9650 for a free estimate.
Why San Jose Residents Choose Us for Mr-Glass Service
Most contractors in San Jose know windows. Few know Mr-Glass windows the way we do. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College, where the curriculum covered framing, concrete, and project estimating before he ever took a paying job. That training turned into two decades of hands-on residential work, and a big share of what we see now in San Jose is Mr-Glass hardware that has aged poorly: worn rollers, failed corner seals, and single-pane aluminum frames that predate modern energy codes. We know which Mr-Glass series fail in which ways, and we stock the parts to fix most of it same-visit. See our broader Mr-Glass sales & service page for how we handle the full product line.
Common Mr-Glass Construction Problems We Solve in San Jose
- Worn or disintegrated roller assemblies on 7700 sliding windows. We see this constantly in Berryessa and Cambrian, where decades of dust plus seismic settling have ground the original nylon rollers down to the metal housing. The window drags, sticks, or drops off its track. We replace the roller assemblies with OEM parts when available, or commercial-grade equivalents that outperform the originals.
- Failed corner seals and moisture intrusion on 8100 single-hung windows. San Jose’s older ranches often have unflashed nail flanges, meaning any seal failure lets water straight into the wall cavity. Fogging between panes is the tell, but the real damage is drywall staining and frame rot we find once the trim comes off. We flash the rough opening properly when we replace these units.
- Mis-set or corroded patio door rollers and tracks on 5800 sliders. After minor quake movement on expansive clay, these doors bind or derail entirely. The track gets gouged, the rollers corrode, and the door ends up leaning against the jamb. We re-level the track, replace the hardware, and test the door through fifty open-close cycles before we call it done.
- Hard-water etching and failed gaskets on Mr-Glass frameless shower enclosures. San Jose’s water is hard, and over years it etches the glass surface beyond polishing. Gaskets also crack from seasonal humidity shifts between the dry summer months and winter rains. We can replace individual glass panels or the full enclosure, and we quote it both ways so you can decide.
- Single-pane aluminum frames that fail Title 24 energy requirements. Many San Jose homes still have original Mr-Glass single-pane aluminum windows that leak conditioned air year-round. When we replace them with dual-pane units during a seismic retrofit, the home gets quieter, tighter, and compliant in one pass.
BeforeAfterMr-Glass Service in San Jose: What Local Conditions Mean for Your Equipment
Here’s the thing about San Jose that most window contractors won’t tell you. The Santa Clara Valley floor sits on Altamont-series clay soils that expand when winter rains arrive and contract dramatically through our dry summers. That seasonal movement is why door frames rack, stucco cracks, and window rollers on Mr-Glass 7700 sliders fail prematurely in Berryessa and East San Jose at rates you won’t see in Los Gatos or Sunnyvale, where the soils and moisture cycles are different. When a homeowner calls us about a sliding window that has suddenly become hard to operate, our first question is always about the foundation: any recent cracks, any doors sticking? Because glass problems in San Jose are often structural problems showing up at the window. We fix the glass, but we tell you what’s underneath it. That’s the difference between a repair that lasts two years and one that lasts twenty.
Mr-Glass Models & Products We Service in San Jose
We work on the full Mr-Glass line that shows up in San Jose homes: the 7700 Series horizontal sliding windows, the 8100 Series single-hung windows, the 5800 Series patio doors, and custom frameless shower enclosures. For rollers, locks, and weatherstripping, we source OEM Mr-Glass parts through local distributors when the series is still in production. For older or discontinued series, we install equivalent commercial-grade hardware that meets or exceeds the original specs. We also stock common replacement parts locally for fast San Jose turnaround, so a roller replacement doesn’t mean waiting a week for a part to ship from a warehouse in Ohio.

Mr-Glass Service Pricing in San Jose
The price of Mr-Glass work in San Jose depends on the series, the failure mode, and whether you’re repairing or replacing. Here are the ranges we quote most often:
| Service | Price Range |
|---|---|
| Window Replacement | $5,310-$17,700 |
| Impact Window Installation | $9,440-$29,500 |
| Frameless Glass Shower Enclosures | $5,310-$14,160 |
A roller replacement on a 7700 slider is a fraction of a full window replacement. A failed insulated glass unit on an 8100 is usually cheaper than chasing recurring seal fixes. We give you a written, line-item estimate before any work starts, and that number doesn’t move without a signed change order. Call (470) 298-9650 for your free estimate.

FAQs - Mr-Glass Construction in San Jose
Yes. In most San Jose homes, the 7700 roller assemblies can be replaced without removing the frame. We pop the sash out, swap the rollers, clean the track, and reinstall. The exception is when frame corrosion or seismic racking has distorted the channel itself, in which case a new window is the honest recommendation.
Fogging between panes means the insulated glass unit’s seal has failed. San Jose’s dry summers aren’t the direct cause, but the wide seasonal swing between summer drought and winter rain stresses the seal over time, especially on unflashed nail flanges in older ranches. Once the seal fails, the fix is replacing the IGU or the whole sash. Call (470) 298-9650 for a quote on either option.
We see it often. Minor quake movement shifts the door frame on expansive clay soils, which misaligns the rollers and causes the door to bind or derail. The rollers rarely survive the misalignment. We re-level the track, replace the roller hardware, and often add a stainless track insert to prevent recurrence. It’s one of the most common Mr-Glass repair calls we get in San Jose.
Yes, we can replace individual glass panels without rebuilding the entire enclosure. San Jose’s hard water etches the surface over years, and once the etching is deep, no polishing compound will restore it. We quote both single-panel replacement and full enclosure replacement, so you can compare the numbers. Estimates are free: (470) 298-9650.
Almost always yes. San Jose homeowners doing foundation retrofits on 1950s-70s cripple-wall ranches in Berryessa and East San Jose find that upgrading original Mr-Glass single-pane windows to dual-pane at the same time gives them one permit cycle, one inspection, and one disruption instead of two. The energy savings on dual-pane pay back part of the cost, and the home is ready for the next quake with windows that won’t shatter the way old single-pane aluminum often does.
