Mr-Glass Construction in Mount Hermon, CA | Viceroy Construction
We provide independent Mr-Glass window, patio door, and glass enclosure service across Mount Hermon, and the single thing that separates our work here is canopy management. Redwood shade and trapped moisture cause Mr-Glass units in Mount Hermon to fog, rot, and bind faster than almost anywhere else in the Bay Area. If your Mr-Glass windows have gone cloudy or your sliding door drags, call Viceroy Construction at (877) 358-6557 for a straight diagnosis and a free estimate. Mr-Glass sales & service is a core part of what we do, and we know these units down to the seal and roller.
Why Mount Hermon Residents Choose Us for Mr-Glass Service
We’ve spent years installing and servicing Mr-Glass windows, patio doors, and glass enclosures, so we know how these units are built, how they fail, and where to source the right parts. That matters in Mount Hermon because the failure mode here is rarely the glass itself. It’s the frame, the flashing, the drainage path, the roller track. Neil Drummond, our owner, trained in the building trades program at West Valley College and has spent the better part of three decades doing residential work across the South Bay. He still walks every job before calling it done. The details you don’t see are the ones that matter most.
We’re an independent contractor, not affiliated with or authorized by Mr-Glass. That’s a feature, not a disclaimer. Our recommendations come from what actually holds up under a redwood canopy, not a manufacturer script. We use OEM Mr-Glass glass units, rollers, and weatherstripping wherever those parts are still available. When they aren’t, we match by profile and dimension with quality aftermarket parts that fit and function correctly. Mount Hermon service area coverage is our home turf, and we quote honestly because we’re the ones who have to stand behind the work.

Common Mr-Glass Construction Problems We Solve in Mount Hermon
- Fogged dual-pane insulated glass units. Seal failure is the most common Mr-Glass call we get in Mount Hermon, and the marine fog plus low sun exposure never bakes the sash dry the way it would over the hill in Los Gatos. The glass unit fails, the frame stays wet, and the problem compounds. We replace the IGU and, where the frame is sound, keep it.
- Rot and soft wood at the sill and frame corners. Older Mr-Glass units in Mount Hermon sit under redwood duff that traps moisture against the exterior trim twelve months a year. Sills go soft, corners crumble, and the window starts to sag. We replace rotted sections, re-flash the rough opening, and reset the unit with trim that sheds water instead of holding it.
- Sliding patio door rollers and tracks gumming up. Redwood needles and grit work their way into Mr-Glass sliding door tracks and chew up rollers fast. Doors bind, jump the track, or refuse to seal. We pull the panel, clear the track, replace rollers, and adjust the door so it glides and latches again.
- Failed weatherstripping and gasket shrinkage. North-facing units in Mount Hermon stay shaded and damp through the summer fog season, so gaskets never get a dry cycle. They shrink, crack, and pull away from the frame. We replace weatherstripping with moisture-tolerant material spec’d for canopy shade rather than sun exposure.
- Framed and semi-frameless shower enclosure leaks and misalignment. In a damp climate, shower enclosures take on extra water and cleaning chemical exposure. Seals degrade, hinges sag, and glass pulls out of square. We re-align, re-seal, and replace hardware so the enclosure drains and closes properly.
Mr-Glass Service in Mount Hermon: What Local Conditions Mean for Your Equipment
Because Mount Hermon sits under a dense redwood canopy, exterior glass and frames here stay damp and shaded for months at a time. Glazing that would dry out and last fifteen years on a sunny Los Gatos hillside often fogs and rots twice as fast in a shaded Mount Hermon canyon. We spec drainage, flashing, and moisture-tolerant trim specifically for canopy shade rather than sun exposure. On a 1940s redwood-sided cabin off a steep wooded lot in Mount Hermon (ZIP 95041), we replaced a set of fogged Mr-Glass dual-pane windows whose sills had gone soft from trapped redwood duff and year-round damp, similar to Lompico Mr-Glass service conditions. We pulled the failed insulated glass units, replaced rotted sill sections and weatherstripping, re-flashed the rough openings, and reset new units with trim that sheds water under the canopy. The homeowner got clear glass and a frame that won’t wick moisture the way the old one did. That job is the template for how we approach every Mr-Glass repair in Mount Hermon.
Mr-Glass Models & Products We Service in Mount Hermon
We service the full range of Mr-Glass products you’re likely to find in Mount Hermon homes: vinyl single-hung and double-hung replacement windows, sliding glass patio doors, fixed and awning windows for shaded exposures, and framed and semi-frameless shower enclosures, just as we do with Mr-Glass in Ben Lomond. On fogged IGU-only failures, we replace the glass unit and keep a sound frame. When frames are rotted or out of square from years of moisture, we tell you honestly that replacement beats repair. We keep common Mr-Glass roller assemblies, weatherstripping profiles, and IGU dimensions stocked for fast Mount Hermon turnaround, so you’re not waiting on a distributor while your window leaks.

| Service | Price Range |
|---|---|

What drives the cost in Mount Hermon is access and rot. Steep, wooded lots mean staging and debris removal take longer. Rotted sills and out-of-square openings mean more carpentry before the new unit goes in. A simple IGU swap on a sound frame runs low in the range; a full replacement with flashing, trim, and structural repair runs higher. Every estimate includes a written line-item breakdown. Call (877) 358-6557 and we’ll walk the job with you.

FAQs – Mr-Glass Construction in Mount Hermon
Does the redwood canopy affect window installation in Mount Hermon? Yes, and it’s the single biggest factor we plan around. Shade and trapped duff keep frames damp, so we spec drainage and flashing details that most installers skip in sunnier towns. If your windows sit under a full canopy, call (877) 358-6557 and we’ll tell you exactly what the moisture is doing to your frames.
Are you an authorized Mr-Glass dealer? No. We’re an independent contractor that installs and services Mr-Glass products. That means we’re free to tell you when an OEM part is worth paying for and when a quality aftermarket match will perform the same for less.
Do you use OEM Mr-Glass parts? We use OEM Mr-Glass glass units, rollers, and weatherstripping wherever the part is still available. When Mr-Glass has discontinued a profile, we match by dimension and material with aftermarket parts that fit correctly. We’ll never force a mismatched part into your frame.
How long does Mr-Glass window service take in Mount Hermon? A typical IGU replacement on a sound frame takes one visit, usually a few hours. Rot repair, re-flashing, and full window replacement can run two to three days depending on access and what we find in the rough opening.
How much does fogged window repair cost in Mount Hermon? Most IGU-only replacements fall between $400 and $1,800 per opening depending on size and glass type, but if the frame is rotted, you’re better served by full replacement in the $4,500 to $15,000 range. We’ll give you both numbers on the same visit. Call (877) 358-6557 and we’ll come out free.
