Mr-Glass Construction in Seven Trees, CA | Viceroy Construction
We provide independent Mr-Glass service in San Jose and across Seven Trees, from fogged dual-pane swaps on Monterey Road to full seismic-retrofit replacements on 1950s tract homes. The thing that makes our Mr-Glass work different here is that we already know how Santa Clara County permit review treats window swaps in an unincorporated pocket, which saves Seven Trees homeowners weeks of back-and-forth. Call (877) 358-6557 for a free estimate on any Mr-Glass repair or replacement in the 95111 ZIP.
We’re Viceroy Construction, a full-scope general contractor led by Neil Drummond. We handle Mr-Glass sales & service as one part of the broader remodeling work we do across the South Bay, but we’re not a Mr-Glass authorized dealer and we don’t pretend to be. What we are is a contractor that has pulled apart enough Mr-Glass units in this neighborhood to know exactly what fails, why it fails here specifically, and whether a repair will hold or you should replace the sash entirely.
Why Seven Trees Residents Choose Us for Mr-Glass Service
Neil trained in the building trades program at West Valley College in Saratoga, where the framing and structural coursework stuck with him. That background matters when Mr-Glass work in Seven Trees turns into a structural question, which it often does. An older wood-frame home with a racked slider isn’t just a window problem. It’s usually a shear-wall or foundation-settlement problem showing up at the window opening, and if you don’t address that, the new unit goes out of square within a few seasons.
We stock OEM Mr-Glass replacement rollers, sashes, and weatherstripping for like-for-like repairs on 200 Series sliding doors and 400 Series single-hungs. When full replacement makes more sense, we recommend quality aftermarket vinyl or fiberglass units with current low-E coatings and better air-infiltration ratings than the originals ever had. The details you don’t see are the ones that matter most, which is why we walk every rough opening, check flashing, and look for rot before we quote a single number.

Common Mr-Glass Construction Problems We Solve in Seven Trees
- Aluminum slider tracks that bind and corrode. Seven Trees summers are hot and dry, which pulls dust into single-pane original sliders, and the wet winters add moisture cycling that corrodes the aluminum track. The result is a door you have to shoulder to open. We replace worn rollers, clean and re-lubricate tracks, and tell you honestly if the track itself is too far gone to save.
- Seal failure and fogging in dual-pane units. The inland Santa Clara Valley sees hot afternoon sun and cool nights, and that thermal stress eventually breaks the seal on older dual-pane Mr-Glass units. Foggy glass can’t be deglazed back to clear. We replace the sash with OEM or aftermarket equivalents depending on what’s still available and what makes financial sense.
- Wood-frame rot at rough openings. These 1950s-1980s stucco-over-studs homes have been owner-remodeled for decades, and we routinely find unflashed gaps where an addition met the original stucco. Water gets in, the frame rots, and the Mr-Glass unit loses its grip in the opening. We cut out the rot, re-flash, and rebuild the rough opening before install.
- Lateral racking that knocks glass out of square. Seven Trees sits near the Calaveras and Hayward faults, and older homes here don’t have the shear-wall connections modern code requires. When the ground moves, windows take the racking. If we see a Mr-Glass unit out of square, we check the structural connection before quoting a replacement, because new glass in an unbraced opening fails the same way.
- Obsolescence of single-pane Mr-Glass profiles. Many original Mr-Glass profiles from the 1960s and 1970s aren’t manufactured anymore. We’ll match what we can with OEM, and when we can’t, we show you aftermarket options that actually beat the originals on energy performance. No pretending a profile exists when it doesn’t.
Mr-Glass Service in Seven Trees: What Local Conditions Mean for Your Equipment
Here’s the thing most window contractors miss when they roll into Seven Trees: this isn’t City of San Jose jurisdiction, and that changes how Mr-Glass in Communications Hill and nearby areas gets permitted. Seven Trees is an unincorporated island completely surrounded by San Jose, so window replacement plans clear Santa Clara County building review, but utility and street standards on the San Jose side can still influence setback and egress interpretations. We’ve had projects on Monterey Road where the county reviewer passed the window plan and the utility-side standard flagged the egress size. Plans that clear one reviewer get flagged by the other, and if you don’t field-check which reviewer will look at what before pulling the permit, your Mr-Glass project sits in limbo for weeks. We’ve been through this enough times in Seven Trees that we pre-check the jurisdiction conflicts before we pull anything, so you’re not paying a crew to stand around waiting on a county stamp.
For Mr-Glass owners specifically, that split jurisdiction also affects how repairs versus replacements are classified. A like-for-like sash swap might not trigger a plan review, but a full rough-opening rebuild with new shear-wall nailing absolutely does. Knowing where that line sits in Seven Trees specifically is the difference between a two-week project and a two-month one.
Mr-Glass Models & Products We Service in Seven Trees
We work on the full Mr-Glass residential line that shows up in Seven Trees homes. That includes the 400 Series single-hung windows, which are the most common units in this neighborhood’s original construction. The 200 Series sliding glass doors are a close second, usually on the rear elevation where a patio or garage conversion happened. We also service 300 Series casement windows and 100 Series fixed picture windows, both of which pop up in the larger ranch footprints near Monterey Road.
Our parts approach is simple. We keep OEM Mr-Glass rollers, sashes, and weatherstripping stocked for fast repair turnaround, especially on 200 Series sliders and 400 Series single-hungs. For full replacements, we carry aftermarket vinyl and fiberglass lines that meet or exceed current Title 24 energy standards, which often puts them well ahead of the original Mr-Glass Glass specs from 40 or 50 years ago.

AfterMr-Glass Service Pricing in Seven Trees
What you’ll pay in Seven Trees depends on whether we’re repairing a sash or replacing a full rough-opening unit, and whether structural work is required. A like-for-like sash repair on a Mr-Glass 400 Series runs lower than a full unit swap, but once we’re into re-flashing a rotted opening or adding shear-wall nailing, the scope and cost climb. Here are the two most common scenarios, both including labor, materials, and permit coordination where applicable.
| Service | Price Range |
|---|---|
| Window Replacement (Mr-Glass or aftermarket equivalent) | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
Every free estimate includes a full rough-opening inspection, an honest read on whether repair will hold, and a written line-item quote with no change orders once we agree on scope. Call (877) 358-6557 to schedule yours.

FAQs – Mr-Glass Construction in Seven Trees
Yes, in most cases. Seven Trees falls under Santa Clara County building review, and any window replacement that changes the rough opening, adds structural anchoring, or alters egress dimensions requires a permit. A like-for-like sash swap on the same opening often doesn’t trigger a plan review, but we confirm that on a case-by-case basis before work starts. Call (877) 358-6557 and we’ll tell you exactly what your project needs.
Usually, yes. Sticking Mr-Glass repair in Cambrian Park and Seven Trees for 200 Series sliders are typically a roller and track problem, not a door-frame problem. We replace the OEM rollers, clean the track, and adjust the alignment, and that resolves most cases. If the track is corroded through or the frame is racked from seismic movement, we’ll tell you straight and show you replacement options instead.
The original single-pane Mr-Glass units from the 1960s and 1970s are not great for Seven Trees summers. They transfer heat directly and lack the low-E coatings that current Title 24 standards require. Modern aftermarket vinyl or fiberglass units with dual-pane low-E glass will cut your cooling load noticeably. If you’re keeping original Mr-Glass frames but replacing sashes, we’ll show you the best glass package available for that profile.
Seven Trees is unincorporated, so county planning and building review handles the permit, but San Jose-side utility and street standards can still influence egress and setback interpretations. That dual review adds time if the two reviewers flag different things. We field-check the jurisdiction conflicts before pulling the permit, which keeps the timeline predictable. It’s practical detail most contractors only learn after their first Seven Trees project stalls.
In most cases, yes. We can match frame profiles and grid patterns with aftermarket units that look similar to your existing Mr-Glass windows, and for 400 Series single-hungs we often use OEM sashes for exact matches. If the original profile is discontinued, we’ll show you the closest visual match in a current product line. Call (877) 358-6557 for a free matching assessment.
