Mr-Glass Construction in Sunnyvale, CA | Framework Contractors
We provide independent Mr-Glass window and door service across Sunnyvale, from full replacements to repair work on original 4000 Series aluminum sliders still hanging on in 1950s and 60s ranch homes. What makes our Mr-Glass work different in Sunnyvale is that we plan every installation around the city’s notoriously tight permitting review, especially for older 94086 ranch blocks near downtown. We’re Framework Contractors, led by Noel Carbajal, and we’ve been servicing Mr-Glass units in this housing stock long enough to know which fixes actually last here. Call (844) 681-3590 for straight answers and a free estimate.
Why Sunnyvale Residents Choose Us for Mr-Glass Service
We’ve installed and serviced Mr-Glass in Santa Clara area homes, including Sunnyvale’s post-war ranch and Eichler tracts, for over a decade. That matters because a Mr-Glass 4000 Series window in a 1963 ranch on a 94086 street fails differently than the same window in a newer build two towns over. We know the corrosion patterns, the seal failures, the roller wear points, and the track misalignment issues that show up consistently in this housing stock.
Noel Carbajal grew up in the Willard neighborhood of Santa Ana, patching stucco and reroofing porches with his uncle before he could drive. He studied construction technology at Santiago Canyon College and has spent close to three decades building and remodeling across the Bay Area and Southern California. Building it right the first time is how he runs every job. The second time costs twice as much and nobody’s happy.
When we work on a Mr-Glass in Cupertino or Sunnyvale unit, we’re not guessing. We source OEM Mr-Glass parts for critical components when available and use quality aftermarket equivalents for discontinued lines so you’re not stuck paying for a full replacement when a roller swap or glazing reseal will do the job.

Common Mr-Glass Construction Problems We Solve in Sunnyvale
- Aluminum frame corrosion and pitting on original 1950s and 60s units. Sunnyvale’s seasonal rain and marine air work their way into old aluminum frames, and we see pitted, chalky metal on 4000 Series sliders throughout the 94085 and 94086 ZIP codes. We’ll tell you honestly when a frame is beyond repair and replacement beats another patch job.
- Failed glazing seals and fogged dual-pane glass. Mr-Glass 4000 Series windows commonly lose their seal after 15 to 20 years, and Sunnyvale’s temperature swings between cool mornings and dry summer afternoons accelerate that breakdown. Fogged glass isn’t just cosmetic. It means the insulating gas is gone and the unit is underperforming.
- Sliding door roller wear and track misalignment on Mr-Glass 9000 Series doors. In older Sunnyvale homes where the original slab has settled over six decades, the door frame shifts with the foundation. Rollers wear unevenly, tracks bind, and the door starts fighting you every time you open it. We can often replace rollers and re-align the track without pulling the whole door.
- Window frame rot and water intrusion at the sill. We frequently find rotted wood framing behind Mr-Glass units installed during previous remodels in Sunnyvale’s ranch homes. Seasonal rain finds the gaps, and by the time you see staining on the interior wall, the sill is already compromised. We address the opening before installing the new unit, not after.
- Single-pane aluminum windows that can’t keep up with Sunnyvale’s energy expectations. Much of Sunnyvale’s housing stock still runs original single-pane Mr-Glass units or early dual-pane replacements that have long since failed. With the city’s push toward energy-efficient upgrades, homeowners here are swapping those old units for modern vinyl and impact-rated glass at a steady pace.
Mr-Glass Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Sunnyvale’s planning department routinely scrutinizes two-story rebuilds in the older 94086 ranch blocks for solar-access and setback impacts on neighbors. What that means for your Mr-Glass windows and doors is simple: if you’re adding square footage or changing the fenestration pattern on a remodel, your window and door replacement can trigger a design review before the city will sign off. We plan Mr-Glass installations around that review timeline so your project doesn’t stall at the counter on Homestead Road or somewhere off Washington Avenue while a planner reviews your setback math. Most General Contractor in Sunnyvale teams learn this the hard way the first time a permit gets kicked back. We’ve already learned it.
On a teardown-rebuild off Murphy Avenue, we replaced a full run of original Mr-Glass 4000 Series aluminum sliders that had corroded frames and fogged glass with new 8000 Series vinyl units. The homeowner also wanted an impact-rated picture window on the street side, so we sourced Mr-Glass 5000 Series glass with the right rating and shimmed the openings to accommodate the new two-story framing. We finished the install and passed the city’s fenestration inspection without a single callback.
Mr-Glass Models & Products We Service in Sunnyvale
We service the full Mr-Glass line you’ll find across Sunnyvale homes. That includes the Mr-Glass 4000 Series aluminum sliding windows, the 8000 Series vinyl single-hung windows, the 9000 Series sliding glass doors, and the 5000 Series picture windows. For critical components like rollers, weatherstripping, and glazing, we source OEM Mr-Glass parts when they’re available. For discontinued lines, we use quality aftermarket equivalents that match or exceed the original spec, so you’re not forced into a full replacement just because the factory stopped making a roller assembly in 2004. If a unit has multiple failed seals or significant frame damage, we’ll give you a straight answer about whether replacement is the smarter move, especially with Sunnyvale homeowners increasingly looking at energy-efficient upgrades as part of broader remodels. See our Mr-Glass sales & service page for more detail on how we approach the brand.

AfterMr-Glass Service Pricing in Sunnyvale
Window replacement in Sunnyvale typically runs between $4,500 and $15,000 depending on the number of units, frame condition, and whether you’re upgrading to impact-rated glass. Impact window installation is a larger investment at $8,000 to $25,000, driven by the glass rating and the framing work involved. Many Sunnyvale homeowners fold Mr-Glass window work into a Home Remodeling in Sunnyvale project like a full kitchen remodel, where the combined scope ranges from $14,000 to $45,000. Here’s how the common scopes break down:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Full Kitchen Remodeling | $14,000 – $45,000 |
What drives your price is the condition of the openings behind the old Mr-Glass units, how many windows or doors are involved, and what the city review timeline looks like for your block. Our free estimate includes a written line-item breakdown, and we don’t change the number after work starts unless you change the scope. Call (844) 681-3590 to schedule one.

FAQs – Mr-Glass Construction in Sunnyvale
In most cases, yes. Sunnyvale treats window and door replacement as a fenestration change, and when it’s combined with any square footage addition or opening modification, the older 94086 ranch blocks can trigger design review. We handle the permit paperwork, pull the permit, and make sure the installation passes inspection the first time. Call (844) 681-3590 and we’ll check your specific address against the current review map.
Most sticking Mr-Glass 9000 Series doors can be repaired. The usual culprits are worn rollers, a track that has shifted with slab settlement, or debris built up in the track channel. We start with roller replacement and track re-alignment, which is a fraction of the cost of a new door. If the frame itself is corroded or the glass seal has failed too, we’ll show you the door and let you decide.
Yes. Mr-Glass produces current lines that fit the rough openings of mid-century ranch construction, and for discontinued series we source compatible parts and equivalent aftermarket components. You don’t have to rip out your original framing to upgrade. We measure the existing openings and spec new units to fit what’s there. Call (844) 681-3590 for a measurement visit and exact pricing.
Sunnyvale enforces Bay Area seismic requirements on any structural opening change, including window and door replacements that enlarge or reconfigure openings. That means additional strapping, proper anchoring to the framing, and in some cases engineered shear panels around larger openings. We build to current seismic spec on every install, not just the ones where an inspector happens to be watching.
We do it regularly. A kitchen remodel in a 1950s Sunnyvale ranch often includes replacing the window over the sink or a sliding door that opens to the backyard, and we coordinate the Mr-Glass work with the cabinet and countertop schedule so the trades don’t trip over each other. One contract, one point of contact, and the window install lines up with the rest of the project. Call (844) 681-3590 to talk through your scope.
