Mr-Glass Construction in Mentone, CA | Stallion Contractors
We’re an independent construction contractor providing Mr-Glass window, door, and glass service across Mentone, CA. What makes our Mr-Glass work different here is that we evaluate every unit against the fire-hardening demands of the wildland-urban interface, not just against a manufacturer spec sheet. From Mr-Glass sales & service experience gathered on actual Mentone foothill jobsites, our crews know how these frames and glazing assemblies perform when Santa Ana wind cycles and chaparral grit meet an older mountain-edge home. If you have fogged dual-panes, binding slider tracks, or frames that never sealed right, call us at (855) 600-3192 and we’ll give you a straight answer on repair versus replacement.
Why Mentone Residents Choose Us for Mr-Glass Service
We’ve installed and serviced Mr-Glass vinyl single-hungs, double-hungs, sliding patio doors, and fixed picture windows across the Mentone foothills for years. That’s a different education than reading a dealer manual. Ruben Montoya, our owner, grew up in Colton off Pepper Avenue and picked up his construction foundation at San Bernardino Valley College, where the program put him on actual job sites before he ever had a business card. He’s spent two-plus decades learning what happens to a window frame when the sun beats on it from June through October and the wind carries embers up from the Crafton Hills. Our crews respect the brand, but we’re not showroom salespeople. When a Mr-Glass unit fails, we tell you whether it’s a simple reseal, a hardware swap, or a full replacement, and we use OEM parts when the frame is sound.

Common Mr-Glass Construction Problems We Solve in Mentone
- Dry-cracked elastomeric glazing seals. The semi-arid UV and Santa Ana wind cycling in Mentone dries out the vinyl frame seals faster than you’d see on the valley floor. Once those seals pull away, wind-driven embers and water have a direct path behind the glass. We pull the sash, clean the channel, and install new OEM seals that actually grip.
- Sliding patio door rollers and tracks binding with chaparral grit. Ash and fine grit from the foothills work into the bottom channel of Mr-Glass sliders and lock the rollers up. The door won’t latch clean, which is a real problem in a fire zone where the door has to seal tight against ember intrusion. We extract the packed debris, replace corroded rollers, and re-align the track so the door closes flush.
- Fogged dual-pane units on older homes. Many mid-century Mentone homes still have original or early Mr-Glass dual-panes. Once the seal fails and fog forms between the panes, the unit loses its insulative value and no longer meets ignition-resistant expectations when the home is being brought up to code. We evaluate whether a glass pack replacement makes sense or if the whole sash needs replacing.
- Improperly flashed or shimmed frame installations on slope lots. Mentone’s east-side slope lots shed hillside drainage straight toward the foundation. If the original window installation was shimmed wrong or the flashing was cut short, water gets behind the frame, rots the rough opening, and loosens the anchors over time. We re-flash and re-shim as part of any replacement.
- Single-pane Mr-Glass units that can’t meet fire-hardening expectations. Older homes in Mentone sometimes still have single-pane units. When a homeowner is bundling a window upgrade with a defensible-space project, those single-panes typically get swapped for dual-pane tempered glass as part of the ignition-resistant assembly.
Mr-Glass Service in Mentone: What Local Conditions Mean for Your Equipment
Here’s the thing most window replacement bids in the Inland Empire won’t tell you: Mentone sits at the foot of the San Bernardino Mountains along the Crafton Hills, in a wildfire-prone wildland-urban interface zone. Construction here isn’t the same as generic valley tract work. Exterior glazing gets evaluated as part of a fire-hardening package, which means ember-resistant venting, ignition-resistant exterior details, and tempered or dual-pane glass all come into play on the same scope. A window replacement on a home along Garnet Street or any of the foothill-adjacent roads in the 92359 zip is often bundled with defensible-space upgrades rather than done as a standalone swap. Valley-floor contractors a few miles west don’t face the same Chapter 7A-style ignition-resistant material demands. That’s why we pull the whole opening apart when we quote a Mr-Glass replacement here. We look at what’s behind the frame, how the flashing was originally run, and whether the glazing spec actually meets what a fire-hardened Mentone home requires.
Mr-Glass Models & Products We Service in Mentone
Our crews work on the full Mr-Glass residential line: vinyl single-hung and double-hung replacement windows, sliding glass patio doors, fixed picture windows, awning windows, and tempered glass shower or interior glass units. When a frame is structurally sound, we source OEM replacement glass, seals, rollers, and hardware. When OEM parts are discontinued or a better-rated aftermarket assembly is needed to meet fire-hardening standards, we switch to quality glazing and hardware and tell you exactly why. We keep common Mr-Glass replacement components stocked for fast turnaround in Mentone, so a reseal or roller job doesn’t stall while parts ship from a warehouse.

AfterMr-Glass Service Pricing in Mentone
| Service | Typical Range in Mentone |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
What drives the number is the condition of the rough opening, the number of units being replaced, whether we’re re-flashing against hillside drainage, and whether the glazing spec is being upgraded for fire hardening. A simple glass pack replacement on one sash runs far less than a full-frame replacement on a slope lot that needs rot repair and new flashing. Every estimate includes a written line-item scope. No change orders on work we’ve already scoped. Call (855) 600-3192 and we’ll walk the openings with you before we quote anything.

FAQs – Mr-Glass Construction in Mentone
Can my Mr-Glass windows be upgraded for the Mentone fire zone without a full replacement?
Yes, in some cases we can upgrade existing Mr-Glass frames with tempered dual-pane glass and new ember-resistant seals without replacing the entire window. It depends on whether the frame itself is still sound and whether the rough opening is properly flashed. Call (855) 600-3192 and we’ll tell you what your specific units need after looking at them.
Why do my Mr-Glass sliding patio doors stick and fail to latch after our dry, windy summers?
Chaparral grit and ash from the Crafton Hills work into the bottom track and clog the rollers, which is a problem we see constantly on Mentone slope lots. Once the track is packed and the rollers corrode, the door binds and won’t seal tight at the latch. We clean the channel, replace OEM rollers and seals, and re-align the track so the door closes flush.
My Mr-Glass dual-pane window is foggy – repair or replace?
If the frame is sound and the fog is from a failed seal, we can often replace the glass pack with a new sealed dual-pane unit. If the frame is warped, the rough opening is rotted, or the fog is a symptom of long-term water intrusion, replacement is the more honest call. We don’t push replacement when a reseal and re-hang will do the job.
Do you handle the flashing and rough-opening work on slope-lot homes in Mentone?
We always do. On Mentone’s east-side slope lots, hillside drainage runs toward the foundation, and a window installation that skips re-flashing or improper shimming will let water behind the frame and rot the rough opening. We pull the trim, inspect the opening, and re-flash every replacement properly before the new unit goes in.
Can you bundle window replacement with my roof and fire-hardening upgrade?
Yes, and that’s one of the reasons Mentone homeowners hire us. We handle windows, roofing, siding, and other exterior work under one contract, so your Mr-Glass replacement can be scheduled alongside a Class A roof replacement or defensible-space upgrades without coordinating multiple vendors. Call (855) 600-3192 for a combined scope and free estimate.
