Mr-Glass Construction in Highland Park, CA | Rowan Construction Group Pasadena
We provide independent Mr-Glass service across Highland Park’s Historic Preservation Overlay Zone, where window and door replacements on street-facing facades must clear design review before permits issue. Our crews have rebuilt Mr-Glass assemblies in over fifty pre-1930 Craftsman bungalows here, and we stock OEM rollers, seals, and spec-matched glass to keep turnaround tight. Call (562) 203-4508 to schedule your free estimate.
Why Highland Park Residents Choose Us for Mr-Glass Service
We’ve logged hundreds of hours specifically on Mr-Glass window and enclosure systems across Highland Park’s Craftsman bungalows and hillside remodels, so we know where these assemblies fail and how to spec them into HPOZ-compliant openings. We are an independent construction provider - not affiliated with, endorsed by, or authorized by Mr-Glass. That independence matters because it lets us source OEM Mr-Glass parts when they’re available and spec-matched aftermarket hardware when OEM lead times would leave your opening exposed to weather or stop-work delays.
Grant Rowan grew up in East Los Angeles, trained at Los Angeles Trade-Technical College on framing, concrete, and finish work, and has spent the last fifteen years building through Pasadena neighborhoods like Bungalow Heaven where old Craftsman stock demands the same close attention to existing structure that Highland Park’s 1905-to-1930 housing requires. We bring that discipline to every Mr-Glass job: written scope before price, material brands named, labor and materials separated so you can compare our quote line for line against any competitor. Under Clause 1 of the Haven Standard, the price is written before anyone starts. Write it down before you build it - scope first, surprises later.
Our technicians are background-checked and uniformed. A live person answers calls 24/7. Every visit includes a documented photo record as standard, not an upgrade. And our Mr-Glass sales & service knowledge runs deep enough that we can tell you whether your failing unit needs a $200 roller swap or a full rebuild before we step onto your property.
Common Mr-Glass Construction Problems We Solve in Highland Park

- Retractable screen cassette springs binding or tearing mesh. Mr-Glass Retractable Screen Door series units bind after years of rubbing against out-of-square jambs common in pre-1930 Highland Park bungalows. The spring fatigue is accelerated by the Arroyo Seco temperature swings that expand and contract aluminum cassettes daily. We replace the spring assembly and shim the jamb plane true, or spec a cassette with more tolerance if the frame is too far gone.
- Fogged or seal-failed dual-pane units. Mr-Glass Studio Series windows facing south or west across Highland Park’s hillsides take brutal Arroyo Seco sun exposure, then catch El Niño-driven wind-driven rain that breaches compromised seals. We measure the IGU (insulated glass unit) thickness and spacer spec, source a replacement that matches the thermal performance, and coordinate with your HPOZ review if the unit sits on a street-facing facade.
- Sliding door tracks derailed by foundation movement. Highland Park’s cut-and-fill hillside lots shift with winter saturation. A Mr-Glass Studio Series slider that ran smooth in September can jump its track by March. We were called to a 1918 Craftsman bungalow off Avenue 60 where exactly this happened. After the geotech report cleared a voluntary retrofit, we re-leveled the opening, reset the door on new OEM rollers, and replaced a fogged Mr-Glass dual-pane unit on the street-facing side with a profile that cleared HPOZ design review. The homeowner got a door that slides clean again and a window package that won’t trigger a stop-work order at final inspection.
- Frameless shower enclosure hinges failing on out-of-plumb tile. Older Highland Park bathrooms, especially in converted back houses or basement units on the hillside parcels, have tile walls that settled out of plumb decades ago. Mr-Glass frameless glass hardware is engineered for square openings; hinge pins and seal strips fatigue fast when the wall plane tilts. We assess whether the tile substrate can be shimmed or whether a semi-frameless spec with more tolerance is the honest recommendation.
- Custom shower enclosures leaking at curb or threshold. On hillside lots where the original floor slab was poured to slope for drainage rather than for level, a Mr-Glass frameless enclosure with a standard bottom sweep won’t seat. We field-measure the slope, spec a custom sweep or a curb modification, and document the water-test with photos before we leave.

AfterMr-Glass Service in Highland Park: What Local Conditions Mean for Your Equipment
Highland Park sits within one of Los Angeles’s largest Historic Preservation Overlay Zones, meaning exterior construction, additions, or renovations on the neighborhood’s dense concentration of pre-1930 Craftsman bungalows require design review and compatibility approval from the City’s Office of Historic Resources - a permitting layer that contractors working just across the border in Glassell Park or El Sereno don’t encounter. Because Highland Park’s HPOZ design standards prohibit non-historic cladding and vinyl on street-facing facades of contributing structures, Mr-Glass window and door replacements on those elevations have to be reviewed for compatible profile and finish before a permit is issued - a step contractors working in adjacent Glassell Park or El Sereno never face. Contractors here must navigate HPOZ guidelines while simultaneously meeting modern LA seismic and Title 24 energy codes, a balancing act that defines nearly every project. We’ve seen competitors spec smooth stucco or vinyl window packages that sailed through permit in other neighborhoods, then hit a hard stop-work order in Highland Park because the HPOZ clearance was skipped. Our pre-bid checklist includes HPOZ submittal timing, design-review board dates, and a library of Mr-Glass profiles that have already cleared review on similar contributing structures. That front-loaded documentation is why our Highland Park jobs finish within a few percent of the written price - no surprises at inspection, no change orders for re-spec’d materials after the fact.
Mr-Glass Models & Products We Service in Highland Park

We work across the full Mr-Glass residential line: Retractable Screen Door series (side-opening and sliding configurations); Studio Series sliding glass door and window systems; custom shower enclosures in both frameless and semi-frameless builds; and patio and French door replacement lines sized for Craftsman-era openings that are narrower and taller than modern stock units. Our Highland Park service area van carries OEM Mr-Glass rollers, springs, seals, and common dual-pane IGU sizes. For hardware on older Studio Series units where OEM has discontinued the part, we source spec-matched aftermarket components rated for the same cycle count and load. We’ll give you a straight repair-versus-replace read - if the frame or jamb plane is compromised, a rebuild usually beats chasing parts. Every recommendation comes with a written scope, brand names named, and a photo record of what we found.

What drives cost: HPOZ design-review submittals add 2-4 weeks to the pre-construction schedule but not to the construction price; hillside geotechnical requirements can add report costs on foundation-impacted jobs; and matching historic profile details on street-facing units may specify a higher-grade finish than a standard white vinyl replacement. Our estimate includes a written scope with labor and materials separated, a 365-Day Done Right Promise, and a documented photo record. Call (562) 203-4508 for an exact quote - estimates are free, and we offer a Free Second Opinion on any written estimate you bring us.

FAQs - Mr-Glass Construction in Highland Park
Yes, but the replacement profile and finish must clear HPOZ design review before permits issue. We submit compatibility documentation to the Office of Historic Resources as part of our pre-construction package, and we maintain a library of Mr-Glass units that have already passed review on similar contributing Craftsman structures. Call (562) 203-4508 to schedule your free estimate.
In Highland Park’s pre-1930 bungalows, it’s usually the frame. Out-of-square jambs from decades of foundation settlement cause the cassette to bind, which overloads the roller and eventually jumps the track. We measure the jamb plane; if it’s within shim range, we true it and replace the OEM roller. If the frame is too far gone, we’ll tell you before we start. Call (562) 203-4508 for an exact quote - estimates are free.
Frameless glass hinges are engineered for plumb walls. In older Highland Park bathrooms - a common focus of Bathroom Remodeling - Highland Park projects, especially converted units on hillside lots - tile substrates settle out of plane and the hinge pin fatigues against the misalignment. The seal strip follows. We assess whether the wall can be shimmed true or whether a semi-frameless spec with more tolerance is the honest fix. Call (562) 203-4508 for an exact quote - estimates are free.
Often yes, if the extrusion and track are sound. We replace fogged dual-pane IGUs, swap failed rollers and locks, and reseat seals without touching the frame. If the frame is corroded, the jamb plane is compromised, or the unit is on a street-facing HPOZ facade where the profile no longer meets design standards, we’ll recommend replacement with a written scope showing both options. Call (562) 203-4508 for an exact quote - estimates are free.
Not for a straightforward window or shower replacement on a stable foundation. If we’re rebuilding an opening that has shifted measurably, or if the job is part of a larger addition or ADU on a cut-and-fill parcel, LA Building may require a geotechnical report and hillside grading review. We flag this in our written scope before any work starts - no surprises. Call (562) 203-4508 for an exact quote - estimates are free.
