Mr-Glass Construction in Van Nuys, CA | Rowan Construction Group Sherman Oaks
We provide independent Mr-Glass sales and service across Van Nuys - not manufacturer-authorized, but factory-trained on the aluminum window and door systems that dominate Valley housing stock. The one thing that sets our Mr-Glass work apart here: we know how Van Nuys’s soft-story retrofit inspection pipeline turns a simple window swap into a code-compliance project, and we quote for that reality upfront.

Why Van Nuys Residents Choose Us for Mr-Glass Service
We’ve been installing and repairing Mr-Glass products on San Fernando Valley homes since before the brand name became common at local suppliers. Mr-Glass sales & service from our crews means working with people who’ve handled the Series 25 sliders on 1970s tuck-unders and the fixed-panel units on post-war ranches - the exact housing stock that fills Van Nuys.
Grant Rowan grew up in Los Angeles, studied construction technology at Los Angeles Valley College in Valley Glen, and has spent the better part of three decades doing construction work across this valley. He can tell when a subfloor isn’t sitting right just by walking across it. That hands-on discipline carries through to how we handle Mr-Glass: we source OEM interchange glazing and weatherstrip where the original profile still exists, switch to quality aftermarket sealed IG units when the extrusion is discontinued, and we stop repairing and quote replacement when the frame is corroded through at the sill or the opening is out of square more than a quarter-inch. Patching a compromised frame just resets the clock on the same leak.
Our written price arrives before any work starts, every time. Under Clause 1 of the Haven Standard, the number you agree to is the number we build to - no change proceeds without a signed change order, which is why our projects finish within a few percent of the original quote across 4,000-plus jobs since 2007.
Common Mr-Glass Construction Problems We Solve in Van Nuys

- Aluminum frame electrolysis at the stucco interface. Van Nuys’s post-WWII ranch homes rarely have proper flashing or weep screed detailing where the window frame meets stucco. The aluminum reacts with alkaline stucco moisture, producing white corrosion bloom that eats through the sill. We see this on Burbank Boulevard corridor homes where the original 1950s-60s installation detail was nothing more than caulk and hope.
- Failed glazing sealant on 1960s-70s tuck-under apartment windows. The desiccated glazing tape on original Mr-Glass single-hung units in buildings along Sepulveda and Van Nuys Boulevard loses its grip, the IG unit fogs, and wind-driven rain tracks down into softened framing. These buildings are already in the soft-story retrofit pipeline, so the window damage gets flagged during the same inspection cycle.
- Thermal cycling damage from 100°F+ summers. Van Nuys runs 10-15°F hotter than the LA coast, and that daily expansion-contraction of aluminum frames against rigid stucco cracks the perimeter seal. We’ve resealed the same opening twice on some Sepulveda corridor buildings before the owner accepted that the frame itself had work-hardened and needed replacement.
- Obsolete single-glazed units with non-tempered glass. Original Mr-Glass fixed lites and jalousie operators on pre-1980s apartment buildings don’t meet current energy or safety code. The latching hardware is often worn past function. These units fail inspection during soft-story retrofit permitting, forcing replacement whether the owner planned it or not.
- Out-of-square openings from Northridge-era structural movement. The 1994 earthquake shifted framing in Van Nuys’s older stock, and subsequent unpermitted additions compounded the problem. A Mr-Glass replacement unit that measured true in the factory won’t seat properly in an opening that’s drifted a half-inch over thirty years. We measure on site, shim to plumb, and document the condition with photos before ordering.

AfterMr-Glass Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys sits in the direct damage corridor of the 1994 Northridge earthquake and holds one of the San Fernando Valley’s densest concentrations of 1960s-70s soft-story tuck-under apartment buildings - the exact structural type that pancaked in that quake. For property owners undertaking Kitchen Remodeling - Van Nuys or similar renovation work, these structural realities shape every project. Los Angeles’s mandatory soft-story retrofit ordinance has put thousands of these buildings on a compliance timeline, and that changes everything about how Mr-Glass window work happens here.
Here’s what we mean. Contractors pulling permits through the Van Nuys LADBS satellite office know that soft-story retrofit inspections on 1960s apartment buildings routinely expose unpermitted rear additions and garage conversions from subsequent decades. Those discoveries trigger mandatory legalization or demolition orders that can double the original project scope before the seismic work even begins. For Mr-Glass owners, this means window and glazing upgrades get swept into the retrofit scope whether you planned them or not - the inspector sees the fogged IG unit or the corroded frame and writes it into the compliance order. That combination of mandatory retrofit inspections plus envelope scrutiny is specific to LADBS jurisdiction in Van Nuys and doesn’t apply the same way across the city line in Burbank or Glendale, where different building departments run different inspection protocols. If you’re also considering Bathroom Remodeling in Van Nuys, the same inspection dynamics may affect your timeline.ls. We’ve learned to quote Mr-Glass replacement on these buildings with contingency language built in, because the opening condition behind the trim often tells a different story than the owner expected.
Mr-Glass Models & Products We Service in Van Nuys

We work with the full Mr-Glass aluminum window and door line: Series 25/26 aluminum-framed window and patio door units; 3000/3000B anodized aluminum sliding window systems; single-hung and fixed-panel aluminum window units sized for retrofit openings; and aluminum patio door and fixed lite assemblies. There’s no Mr-Glass manufacturing plant - it’s a trade name owners buy off the shelf at Van Nuys-area building suppliers, so our crews install it constantly on envelope repairs where it’s actually used.
For parts, we stock OEM interchange weatherstrip, roller and sash hardware, and glazing components for active Series 25 and 3000 profiles at our Van Nuys service area warehouse. Discontinued extrusions get quality aftermarket sealed IG units with stainless fasteners. If your building is in the soft-story pipeline, we can often pre-order replacement units to arrive before the inspection date, keeping your compliance timeline on track.

FAQs - Mr-Glass Construction in Van Nuys
Repair is possible if the frame extrusion is intact, the hardware is still available, and the opening is square within a quarter-inch. We replace the glazing tape, install new sealed IG units, and lubricate the operators. If the sill is electrolyzed through or the frame has work-hardened from decades of thermal cycling, we quote replacement - patching a compromised frame just resets the clock on the same leak. Call (213) 221-0788 for an exact quote; estimates are free.
Yes, frequently. LADBS inspectors walking soft-story retrofits in Van Nuys routinely flag original Mr-Glass units that don’t meet current energy or safety standards - fogged IG units, non-tempered glass, or inoperable hardware get written into compliance orders. The window work gets swept into the seismic scope whether the owner planned it or not. We coordinate our installation schedule with your structural contractor to keep the inspection timeline moving. Call (213) 221-0788 to discuss timing.
The desiccant inside the sealed IG unit has saturated and the glazing tape has lost its seal. Summer’s extreme thermal cycling - Van Nuys regularly exceeds 100°F - expands the air inside the unit, forcing moist air through compromised seals. When temperatures drop at night, that moisture condenses on the interior glass surface. Winter’s smaller temperature swing produces less dramatic fogging, but the seal failure is year-round. The fix is replacement of the sealed IG unit, not defogging spray. Call (213) 221-0788 for an exact quote; estimates are free.
Usually yes, if the opening is in reasonable condition. We remove the existing unit, inspect the sill pan and framing, install the new Series 25 or 3000 slider with proper pan flashing and weep screed detail that the original installation lacked, then patch the stucco perimeter. The stucco itself stays in place. If the opening has shifted from Northridge-era movement or unpermitted addition work, we document the condition and quote any reframing needed. Call (213) 221-0788 for an exact quote; estimates are free.
Impact-rated laminated glass for Mr-Glass frames is available but not a stock item - we order to the specific opening size after field measurement. Lead time is typically two to three weeks. For buildings in the soft-story retrofit pipeline, we coordinate delivery to arrive before your inspection date. The upgrade adds cost but meets current code for ground-floor units in multi-family construction. Call (213) 221-0788 for an exact quote; estimates are free.
