Mr-Glass Construction in Sherman Oaks, CA | Rowan Construction Group Sherman Oaks
We provide independent Mr-Glass sales and service across Sherman Oaks, from the Galleria corridor to the hillside parcels climbing toward Mulholland. The one thing that makes our Mr-Glass work here different: we’ve spent years removing and reinstalling Mr-Glass doors and windows to accommodate mandatory soft-story retrofits on 1960s dingbat buildings, a construction demand that simply doesn’t exist at this volume in neighboring Valley communities.

Why Sherman Oaks Residents Choose Us for Mr-Glass Service
We’ve installed thousands of Mr-Glass door and window systems across the San Fernando Valley, and we’ve learned how its vinyl components behave after a decade of Sherman Oaks heat cycling - the kind that warps sashes and cooks argon fill out of dual-pane units. Our crews carry OEM Mr-Glass replacement sashes, IGUs, rollers, and weatherstripping on the truck, and when a part is discontinued, we source proven aftermarket equivalents and note the substitution on your work order. No mystery, no bait-and-switch.
Grant Rowan, our owner, grew up in Los Angeles and studied construction technology at Los Angeles Valley College in Valley Glen before he ever swung a framing hammer on a paid job. He’s spent the better part of three decades doing construction work across the Valley, and Rowan Construction Group has served Sherman Oaks - including projects near the Galleria and the residential streets off Ventura Boulevard - for several years running. Grant stays hands-on enough that he can tell when a subfloor isn’t sitting right just by walking across it. That same eye goes to every Mr-Glass installation we do here.
Under Clause 1 of the Haven Standard, the price is written before anyone starts. Under Clause 3, no change proceeds without a signed change order. Across 4,000-plus projects since 2007, that discipline has kept final costs within a few percent of the agreed number. Mr-Glass sales & service from an independent crew that answers to you, not a manufacturer.
Common Mr-Glass Construction Problems We Solve in Sherman Oaks

- Vinyl sash and frame distortion on west- and south-facing windows. Sherman Oaks sits in the San Fernando Valley heat basin, routinely hitting 100°F-108°F in summer - 15-20 degrees hotter than coastal LA. That thermal load warps Mr-Glass vinyl sashes until they no longer seat squarely in the frame, creating gaps that leak conditioned air and bind when you try to open the window. We measure the distortion, replace the sash if the frame is still square, or quote full replacement if the frame itself has twisted.
- Seal failure in dual-pane IGUs with fogging between panes. The argon fill escapes and moisture enters, especially on Mr-Glass units installed in the 1990s before high-performance warm-edge spacers became standard. In Sherman Oaks, the daily heat swing - 50°F at dawn to 105°F by afternoon - pumps the IGU seal harder than in moderated coastal climates. We can often replace just the fogged IGU, saving the frame and the trim.
- Sliding glass door roller and track breakdown in 1960s-1970s dingbat apartments. Along Moorpark Street and Van Nuys Boulevard, original Mr-Glass sliding door tracks accumulate grit from decades of foot traffic and parking-lot dust. The rollers flatten, the door drops, and eventually it won’t move without lifting. We pull the door, replace the roller carriage, and mill or replace the track - or upgrade to a current ReliaBilt 600 Series slider if the frame is too far gone.
- Water intrusion at sill pans and perimeter seals on slab-on-grade ranch homes. Sherman Oaks’ post-WWII ranch stock was built with stucco-over-wood-frame construction, and many original window installations were never properly flashed at the sill pan. Wind-driven rain finds the gap, rots the substrate, and stains interior drywall. We cut back the stucco, install proper sill pans and head flashing, then reset the Mr-Glass unit with a sealed stucco-to-frame transition.
- Fire-zone compliance issues on hillside properties above the 405/101 interchange. These parcels fall within LA’s High Fire Hazard Severity Zones, where the LAMC requires fire-resistant construction assemblies. Standard Mr-Glass vinyl windows may not meet the assembly rating without specific glazing and framing combinations. We know which configurations pass inspection and which don’t, because we’ve had the conversation with LA Building and Safety more than once.

AfterMr-Glass Service in Sherman Oaks: What Local Conditions Mean for Your Equipment
Because Sherman Oaks’ dense 1960s dingbat apartment buildings require mandatory soft-story retrofits under LA’s ordinance, we regularly remove and reinstall Mr-Glass sliding doors and windows to accommodate new moment-frame and steel-column work without breaking the exterior envelope. That retrofit-driven door and window reinstallation demand is far heavier here than in neighboring Studio City or Encino. On a 1962 dingbat building along Moorpark Street, our crew pulled the original Mr-Glass sliding glass doors to make way for a soft-story moment-frame retrofit, then set new ReliaBilt 600 Series vinyl sliders with fresh sill pans and sealed the stucco-to-frame junctions before the drywall went back up. The owner had been told the building would be without functioning exterior doors for weeks, but we had the new units in and weather-tight in two days. The result is doors that slide cleanly, pass the retrofit inspection, and keep the units secure for the remaining work. This is the kind of job that repeats across Sherman Oaks in a way it simply doesn’t elsewhere - and it’s why we stock the specific Mr-Glass replacement sizes and hardware that dingbat retrofits demand.
Mr-Glass Models & Products We Service in Sherman Oaks

We work on the full Mr-Glass residential line: ReliaBilt 400 Series vinyl single-hung windows, ReliaBilt 600 Series double-hung windows, ReliaBilt 600 Series vinyl sliding glass doors, and ReliaBilt 300 Series vinyl sliding windows. Our Sherman Oaks warehouse stocks OEM replacement sashes, IGUs, roller carriages, and weatherstripping for the 400 and 600 Series, because those are the units we see most often on local retrofits and ranch-home replacements. When OEM is back-ordered or discontinued, we use high-quality aftermarket equivalents from proven suppliers - and we write it on the work order so you know exactly what you’re getting. Our stance: if the frame is sound and the hardware channel isn’t wallowed out, a targeted repair is almost always the better spend. Once distortion or rot compromises multiple sashes, we lay out full replacement with line-item pricing and let you decide.

FAQs - Mr-Glass Construction in Sherman Oaks
Can you replace just the fogged glass in my Mr-Glass ReliaBilt windows, or do I need entirely new windows?
Yes, we can often replace just the fogged IGU (insulating glass unit) while keeping your existing frame, sash, and trim intact. This works when the frame is square, the hardware operates smoothly, and the vinyl hasn’t distorted from heat exposure. We measure the existing IGU, order a replacement with matching low-E coating and spacer type, and install it with a new seal. Call (213) 221-0788 for an exact quote - estimates are free.
My Mr-Glass sliding door is hard to open after years of Sherman Oaks heat and dust - what is usually wrong?
The roller carriage has likely flattened or seized, and the track has accumulated grit and possibly corroded. On dingbat buildings along corridors like Moorpark Street, we see this constantly - decades of parking-lot dust plus thermal expansion cycling wears the roller axle and deforms the track channel. We pull the door, inspect the roller and track, and quote either a roller replacement or a full track rebuild. Call (213) 221-0788 for an exact quote - estimates are free.
We are planning a soft-story retrofit on our dingbat building near Van Nuys Boulevard - can you handle the Mr-Glass door and window removal and reinstallation?
Yes, this is exactly the work we do most in Sherman Oaks. We coordinate with your structural engineer and general contractor to remove Mr-Glass doors and windows before the moment-frame or steel-column installation, protect the openings, then reinstall with new sill pans, head flashing, and sealed stucco-to-frame transitions. Our crews have done this on dozens of local retrofits. The key is timing: we need the structural schedule and the inspection sequence to avoid leaving units exposed.
Do Sherman Oaks fire hazard zone rules affect which Mr-Glass windows I can use?
Yes, if your property sits above the 405/101 interchange in a High Fire Hazard Severity Zone. The LAMC requires fire-resistant construction assemblies, which means the window unit - frame, glazing, and installation method together - must meet a specific assembly rating. Standard Mr-Glass vinyl configurations may not pass without upgraded glazing or specific framing details. We know which combinations LA Building and Safety has approved, because we’ve submitted the documentation before. Bring your address and we’ll confirm the requirement before quoting.
How do I know whether to repair or replace my older Mr-Glass windows?
Repair makes sense when the frame is structurally sound, the distortion is limited to one or two sashes, and the hardware channels aren’t wallowed out. Replace when multiple sashes are warped, the frame itself has twisted from thermal cycling, or the original installation lacked proper flashing and you’re seeing water intrusion at the sill. We document the condition with photos, explain each line item, and give you both options where they exist. Call (213) 221-0788 for an exact quote - estimates are free.
