Mr-Glass Construction in Ontario, CA | Polaris Contractors
We provide independent Mr-Glass service across Ontario, from folding patio door rebuilds to frameless shower enclosure installs. The reason our Mr-Glass work here is different comes down to one thing: we know how Santa Ana wind pressure cycling and grove-lot soil settlement tear these systems apart in this city specifically. Polaris Contractors is a full-scope general contractor, not a Mr-Glass dealer or authorized installer. Call (855) 473-6535 for a free estimate on any Mr-Glass glass system in Ontario.
Why Ontario Residents Choose Us for Mr-Glass Service
We’ve rebuilt enough Mr-Glass folding doors, sliding assemblies, and frameless shower enclosures in Ontario to know exactly where this brand’s hardware gives out first. Heavy tempered panels are gorgeous when they glide, but they’re unforgiving on tracks that have grit in them. Header extrusions hold up until a wood-frame wall settles underneath them. And the gaskets? Hot, dry summers shrink them until every Santa Ana gust finds a gap.
Rick Sondermann, our owner, learned construction the same way a lot of the old-timers in Ontario did: by taking things apart, looking at what broke, and doing it right the second time. He runs Polaris Contractors with one standard: Do it right the first time – the second time always costs more. That applies to a $4,500 glass shower enclosure just as much as a $220,000 ADU. Our team brings full construction capability to every Mr-Glass job, so when we find a header out of plumb or a post that’s settled, we can fix the structure and the glass in one visit. For more on how we handle the brand across the region, see our Mr-Glass sales & service page.

Common Mr-Glass Construction Problems We Solve in Ontario
- Tempered panel stress fractures from Santa Ana wind pressure cycling. We see this in Ontario neighborhoods where folding doors face the foothills. The wind loads the glass, the frame racks slightly, and over time corner fractures start at the weakest point in the temper. We replace panels and re-anchor frames so the next wind season doesn’t repeat it.
- Rollers and hinges seized with grit in the track. Ontario’s dry, dusty conditions put fine airborne grit on every exposed aluminum track. It works into the roller bearings, and panels start to drag and jump. We strip the track, replace OEM-equivalent rollers, and adjust the alignment so the system moves cleanly again.
- Weathered and shrunk gaskets letting dust and air through. After two or three hot Ontario summers, weatherstripping on Mr-Glass systems hardens and pulls away from the extrusion. We source OEM-compatible gasket profiles and re-seal the system. If a gasket is discontinued, we use quality aftermarket sealing that matches the groove.
- Header and frame deflection from settled wood-frame walls. Many Ontario ranch homes in the 91762 and 91764 ZIPs have original framing that has moved over fifty or sixty years. A Mr-Glass header anchored to that wall can shift just enough to bind the panels. We fix the anchor, not just the glass.
- Shower enclosure leaks at the bottom corners. On frameless Mr-Glass enclosures, we find failed corner seals or a shower curb that has settled slightly out of level. The fix is usually resealing and releveling, not replacing the glass.
Mr-Glass Service in Ontario: What Local Conditions Mean for Your Equipment
In the 91764 ZIP, a lot of Ontario’s postwar homes sit on former citrus groves. That’s a specific detail most contractors never think about, but we’ve learned to check for it before we touch a Mr-Glass frame. The old irrigation lines and buried organic debris left the soil under those wood-frame walls unevenly settled. When we re-anchor a glass header or a folding-door frame in this part of Ontario, we probe the footing soil first. If the post has settled into decomposing grove soil, no amount of track adjustment will fix those binding panels. We re-level the anchor, then rebuild the hardware. In the 91764 neighborhood off those former citrus-grove lots, we pulled a binding Mr-Glass folding patio door whose panels had begun dragging and jumping on the track—similar to Mr-Glass service in Montclair we handle. The rollers were seized with grit and the header was out of plumb because the post had settled into old grove soil. We re-leveled the anchor, replaced the OEM-equivalent roller and hinge set, and re-sealed the gaskets. The panels now fold clean and seal against the wind. That’s the difference between fixing a symptom and fixing what Ontario actually did to the system.
Mr-Glass Models & Products We Service in Ontario
We work on the full range of Mr-Glass architectural glass systems installed in Ontario homes. That includes folding bi-fold patio door systems, sliding glass door assemblies, frameless glass shower enclosures, and fixed glass railing and partition panels. When it comes to parts, we source OEM-equivalent rollers, hinges, gaskets, and header hardware matched to the existing extrusion profile. If a panel is chipped or the frame is out of plumb beyond adjustment, we’ll tell you honestly whether a hardware rebuild or a full system replacement is the better spend. We don’t stock parts for brand names we don’t install. For Mr-Glass, we keep common extrusion profiles and gasket sets on hand for faster Ontario turnaround, plus Mr-Glass repair in Chino.

FAQs – Mr-Glass Construction in Ontario
Yes, in most cases. Dragging and jumping panels usually mean seized rollers and a track full of grit. We strip the track, replace the OEM-equivalent rollers and hinges, and realign the header if it has shifted. If the header post has settled into bad soil, we re-anchor before we adjust anything else. Call (855) 473-6535 for an exact quote – estimates are free.
Leaks at the bottom corners of a Mr-Glass frameless enclosure usually come from two sources: failed corner seals or a shower curb that has settled slightly out of level. We reseal the joints and relevel the curb as needed. The glass itself rarely needs replacement. Call (855) 473-6535 to have us take a look – estimates are free.
Yes. Older Ontario ranch homes in the 91761 and 91762 ZIPs often have wood framing that has shrunk and settled over the decades. We inspect the wall and footing, re-anchor the header extrusion, and then re-align the panels. It’s structural work, so it needs a contractor’s eye and hand, not just a glass tech.
It can. Santa Ana wind pressure cycling loads the glass, the frame racks slightly, and over time corner fractures start. That’s a failure mode we see in Ontario neighborhoods where folding doors face the foothills, and in Mr-Glass in San Antonio Heights homes with similar exposure. We replace panels and re-anchor frames so the next wind season doesn’t repeat it.
No. Polaris Contractors is an independent contractor. We are not a Mr-Glass dealer or authorized installer. That independence means we service the brand’s folding, sliding, and fixed glass systems on their merits, and we make recommendations that favor the homeowner’s budget, not a manufacturer’s sales program.
