Mr-Glass Construction in Los Serranos, CA | Sycamore Contractors
We’re Sycamore Contractors, an independent Mr-Glass service provider working the 91709 hillside corridor. What makes our Mr-Glass work different in Los Serranos is simple: we plan every window, door, and shower enclosure job around wildland-urban interface codes and steep-slope drainage that flatland glazing crews never deal with. If your Mr-Glass unit is dragging, chipped, whistling, or leaking, call (877) 265-6284 for a free estimate.
Why Los Serranos Residents Choose Us for Mr-Glass Service
Most glazing subs work the flatlands of Chino and Ontario, where plumb openings are a given and fire codes stop at the curb. Los Serranos is a different animal. We know Mr-Glass builder-style bypass and pivot shower assemblies, their framed and frameless sliding glass door units, and their tempered window replacements well enough to tell you when a panel can be re-sealed and re-rollered, and when a wall that’s crept after a wet winter means the unit has to be re-set. Nate Calloway, our owner, learned the trade the long way: Palomar College’s construction technology program, then the better part of two decades running crews across hot inland terrain. That background means we check the wall before we order the glass, because a racked opening just re-cracks the next dry spell. We’re Mr-Glass sales & service specialists, but we’re not a factory dealer, and that independence lets us give you a straight answer instead of a brand script.

Common Mr-Glass Construction Problems We Solve in Los Serranos
- Racked sliding doors on hillside parcels. When Los Serranos ground creeps after a wet season, Mr-Glass slider tracks bind and the glass chips at the strike edge. We check plumb and slope drainage first, then re-set or replace the unit so it doesn’t bind again.
- Grit-blasted rollers and seals from Santa Ana events. Wind whipping off the open boundary of Chino Hills State Park pushes ash and dust into perimeter and sliding tracks. That wears Mr-Glass rollers and sweep seals far faster than the flatland wear curve, and it’s a common call for us in 91709.
- Whistling doors and sill leaks after inland heat cycling. Those hot, dry Los Serranos summers cook Mr-Glass sweep seals and glazing gaskets until they shrink and crack. Doors start whistling, and semi-frameless shower bypass panels seep at the sill.
- Fire-hardening mismatches at the rough opening. If your roof, siding, or vents were already retrofitted to WUI spec, the original Mr-Glass framing and flashing often doesn’t line up cleanly anymore. We re-detail the opening so the glass and the fire-resistant shell work together.
- Out-of-plumb shower enclosures on steep lots. Frameless Mr-Glass shower panels rack when a bath wall has settled or crept. We re-plumb the curb and adjust the hinge geometry before setting the glass, which is the difference between a shower that seals and one that leaks at the corner.
Mr-Glass Service in Los Serranos: What Local Conditions Mean for Your Equipment
Here’s the thing people don’t realize until they build or remodel out here: Los Serranos properties backing onto Chino Hills State Park and the Carbon Canyon corridor sit inside the wildland-urban interface, which changes how a window or sliding-door replacement has to be planned. The glazing spec, whether tempered, impact-rated, or both, and the flashing detail at the rough opening, has to be settled before we order. Re-cutting a Mr-Glass unit for a WUI condition after it shows up blows the schedule and wastes money. We’ve worked hillside parcels off Carbon Canyon Road where defensible-space brush clearance and ember-resistant opening requirements dictated a different glass package than the same footprint would demand with Mr-Glass service in Chino. The moving wall matters too. On one Carbon Canyon parcel backing onto the state park, we replaced a set of original Mr-Glass sliders whose track had bound and chipped after the ground moved through a wet winter. We checked wall plumb and drainage before touching the glass, re-flashed the opening to the property’s defensible-space and ember-resistance expectations, then set new tempered Mr-Glass sliders with fresh rollers and gaskets. The doors glide clean because we treated the wall, not just the glass.
Mr-Glass Models & Products We Service in Los Serranos
We handle Mr-Glass semi-frameless shower enclosure assemblies, including builder-style bypass and pivot lines. We also service Mr-Glass framed and frameless sliding glass door units, tempered window and picture-window replacement assemblies, plus their glass-railing and custom-mirror products. On parts: we specify Mr-Glass OEM glass and hardware where it’s still available so track profiles, rollers, and tempered panes match the original unit exactly. When OEM parts are discontinued or priced out of sense, we move to proven aftermarket rollers, sweeps, and gaskets. Honest stance: re-seal and re-roller a sound unit. On a glass panel or frame racked by a moving wall, replace it, because Do it right the first time, or you’ll do it twice in the July heat.

AfterMr-Glass Service Pricing in Los Serranos
What you’ll pay depends on whether we’re re-sealing and re-rollering an existing Mr-Glass unit or pulling and re-setting glass in a wall that’s moved. Los Serranos service area jobs on hillside parcels often run a bit higher than flatland work because the rough opening needs more prep before glass goes in. Here’s the range for common Mr-Glass work in 91709:

| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |

| Shower Replacement | $3,000 – $8,500 |

FAQs – Mr-Glass Construction in Los Serranos
Because Los Serranos hillside and state-park-adjacent parcels sit in the wildland-urban interface, which adds defensible-space and ember-resistant opening details that flatland Chino jobs don’t carry. The glazing spec and flashing detail have to be settled before we order, and hillside openings often need re-plumbing before the new unit can be set, which is why Pomona Mr-Glass service differs from our hillside approach. Call (877) 265-6284 and we’ll give you a straight number.
If the wall plumb checks out and only the rollers and seals are worn, we re-roller and re-seal the existing Mr-Glass unit. If the framing has crept and the opening is out of plumb, a repair just re-cracks the next dry spell; replace the unit and re-detail the rough opening so the new door tracks clean. We’ll tell you which one you actually need after checking the wall.
Yes. Wind-driven grit and ash off the open Chino Hills State Park boundary gets into slider tracks and wears rollers, sweeps, and seals noticeably faster than the flatland wear curve. Los Serranos homes backing onto the park see this the most, and we stock the common replacement parts to turn the work around quickly, unlike the longer turnaround for Mr-Glass repair in Montclair.
Often the glass itself is fine, but the original Mr-Glass framing and flashing no longer lines up cleanly against the new fire-resistant shell. We re-detail the rough opening and, where required, swap to tempered or impact-rated glazing to match the WUI package you already paid for. It’s worth a quick inspection before an inspector flags it.
We can, but only if the curb and walls are plumb first. On Los Serranos hillside baths, we check for settled framing, correct the curb, and set the hinge geometry before the glass goes in. Skipping that step is how frameless panels start leaking at the corner within a year. Call (877) 265-6284 for a free look at your bath.
