Mr-Glass Construction in Los Angeles, CA | Rowan Construction Group
We’re Rowan Construction Group, an independent Mr-Glass installer and servicer working across Los Angeles. We integrate Mr-Glass storefront, skylight, shower enclosure, and curtain wall systems into LADBS-compliant assemblies. The one thing that makes our Mr-Glass work different here: we know which glazing installations trigger structural review and which ones sail through on an over-the-counter permit. Call (470) 298-9650 for a written estimate before anything gets ordered.
Why Los Angeles Residents Choose Us for Mr-Glass Service
Grant Rowan grew up in the Crenshaw district, spent his teens watching that neighborhood cycle through neglect and renovation in roughly equal measure, and then trained in construction technology at Los Angeles Trade-Technical College, where the coursework covered framing, concrete, and project estimating - plus early exposure to Driveway & Pavers - Los Angeles basics - before he ever set foot on a paying job site. That background matters when you’re dealing with Mr-Glass systems in a city where a seismic retrofit ordinance can dictate whether your storefront gets permitted this month or four months from now.
We carry genuine Mr-Glass seals, gaskets, and hardware when lead time allows. When a commercial storefront in a 1960s building needs to be back in service fast, we source structural-equivalent glazing gaskets and silicone from local Los Angeles suppliers that meet CBC Chapter 24 standards. Our team knows the difference between a Mr-Glass 8600 Series storefront that needs new perimeter backer rod and one that needs its entire anchorage recalculated. You’ll get a documented photo record on every visit, included, and a written scope with a flat price before work starts, per Clause 1 of the Haven Standard. For broader context on the work we do, see our Mr-Glass sales & service overview.
Common Mr-Glass Construction Problems We Solve in Los Angeles

- Failed perimeter sealant on Mr-Glass 8600 storefronts after seismic drift. Older LA buildings move during even minor earthquakes, and that movement pulls the perimeter sealant away from the aluminum frame. Water then tracks through the storefront header. We see this in dingbat apartment buildings and pre-1980 commercial storefronts across the city, and the fix involves removing the failed sealant, inspecting the backer rod, and re-sealing with structural silicone after confirming the frame anchorage hasn’t shifted.
- Condensation and seal failure in Mr-Glass 5700 shower enclosures from hard water. Los Angeles water is hard. Mineral deposits etch the bottom rails of 5700 enclosures, compromise the seals, and eventually cause leaks into the bathroom floor assembly. We replace the seals and rails without replacing the glass when the lite is intact.
- Warped aluminum mullions in Mr-Glass 3400 curtain walls on hillside post-tension slabs. Hillside homes in the Santa Monica Mountains and Verdugo Hills sit on slabs that move differently than flatland foundations. That differential movement torques the aluminum mullions and cracks the glass. We re-anchor the mullions to accommodate current lateral drift limits.
- Debris-clogged condensation weeps in Mr-Glass 7900 skylights during Santa Ana wind events. Santa Anas drive fine dust and leaf debris into the weep holes on 7900 Series skylights. Once those weeps clog, condensation backs up and leaks through the interior trim. We clear the weeps, inspect the glazing gasket, and restore drainage.
- Improperly anchored Mr-Glass systems in Wildland-Urban Interface fire zones. Hillside communities throughout the Santa Monica Mountains fall under LADBS WUI requirements. Mr-Glass installations there often need one-hour fire-rated exterior assemblies, and we frequently find existing storefronts and curtain walls that never got that rating. We bring them into compliance.

AfterMr-Glass Service in Los Angeles: What Local Conditions Mean for Your Equipment
Los Angeles enforces the nation’s only mandatory soft-story and hillside seismic retrofit programs, and that has a direct consequence for Mr-Glass owners. Any Mr-Glass storefront or curtain wall installed in a pre-1980 building must carry an engineered anchorage detail for out-of-plane drift. LADBS plan checkers specifically request this detail on commercial glazing permits. No neighboring city applies this requirement to commercial glazing at this scale, which means a Mr-Glass 8600 storefront replacement in Los Angeles isn’t just a glass job. It’s a structural job with glass attached. In a 1960s dingbat apartment building in Palms, our crew replaced a failed Mr-Glass 8600 entry system where the original aluminum jambs had pulled away from the wood framing after minor seismic sway. We removed the entire assembly down to the framing, added steel stiffeners to meet current lateral drift limits, and reinstalled the Mr-Glass system with new perimeter backer rod and structural silicone. LADBS signed off the replacement under an over-the-counter commercial glazing permit because we kept the structural scope within the existing opening. That’s the discipline that gets Mr-Glass work through Los Angeles plan check faster, and it’s the kind of detail we put in writing before anyone picks up a tool.
Mr-Glass Models & Products We Service in Los Angeles

We service the full residential and light commercial Mr-Glass product range: the 8600 Series Aluminum Storefront System, the 7900 Series Concealed Vent Tubular Skylight, the 5700 Series Heavy Glass Shower Enclosure, and the 3400 Series Curtain Wall. For urgent repairs, we stock structural-equivalent aftermarket glazing gaskets and silicone from local Los Angeles suppliers, so we’re not waiting on a manufacturer shipment when your storefront is down. For non-urgent replacements, we order genuine Mr-Glass seals, gaskets, and hardware and keep you informed on the lead time. Our repair-over-replace stance is firm: if the glass lite is intact and only the frame components are compromised, we repair.

FAQs - Mr-Glass Construction in Los Angeles
Yes. Hillside and Valley-floor homes in Los Angeles sit on expansive clay that heaves and shrinks through wet and dry seasons, so we anchor the shower enclosure framing to allow for that movement rather than fighting it. We specify flexible perimeter joints and verify the subfloor is stable before setting any glass. Call (470) 298-9650 and we’ll walk you through what your specific hillside lot requires - the estimate is free.
Condensation between the panes means the insulated glazing unit’s edge seal has failed, which lets moist air into the airspace. In the San Fernando Valley, the wide temperature swings between warm days and cold nights accelerate that failure. The fix is replacing the glazing unit, not the whole skylight, and we can usually do it without disturbing the surrounding roof assembly.
Rowan Construction Group is an independent Mr-Glass installer and servicer, not a manufacturer-authorized provider. Work we perform is covered under our own written warranty, but our service may affect the original manufacturer warranty terms on the specific components we touch. We’ll tell you in writing, before work starts, exactly what the warranty implications are for your specific Mr-Glass product.
We start by identifying where water is entering, which in older Los Angeles buildings is usually failed perimeter sealant or a compromised backer rod at the header. Then we remove the failed material, inspect the frame anchorage for seismic drift damage, and re-seal with structural silicone. If the storefront is in a pre-1980 building, LADBS may require an engineered anchorage detail before we can close the permit. Call (470) 298-9650 for an exact quote on your storefront.
Mullion replacement on a 3400 curtain wall in downtown Los Angeles typically runs between $5,310 and $14,160, depending on the mullion length, access requirements, and whether the surrounding glass needs to be removed and reset. If the building is pre-1980, the permit will also require an engineered out-of-plane drift detail. The fastest way to get a specific number is to call (470) 298-9650 with the mullion dimensions and building age - we’ll put it in writing.
