Mr-Glass Construction in Highland, CA | Polaris Contractors
We service, repair, and install Mr-Glass windows, doors, and frameless shower enclosures across Highland, ZIP code 92346. The thing that separates our Mr-Glass work here from anywhere else is that we build every installation around two Highland realities most contractors miss: wildland-urban interface fire codes and expansive clay soils that move under your slab. We’re Polaris Contractors, an independent Mr-Glass service provider led by Rick Sondermann, and we’ve been working on these products in the Inland Empire for over a decade. Call (855) 473-6535 for a free estimate on any Mr-Glass project in Highland.
Why Highland Residents Choose Us for Mr-Glass Service
We’re independent specialists in Mr-Glass products, not a manufacturer affiliate or authorized dealer. That matters because our loyalty is to the homeowner, not a corporate warranty department. We prioritize OEM parts for critical components like window balances and shower hinges to keep your warranty intact. But when a wear item fails, like weatherstripping or sliding-door rollers, we’ll tell you honestly if a high-quality aftermarket part will actually outlast the original in Highland’s heat and dust. Rick Sondermann grew up in Corona del Mar and learned construction fundamentals at Saddleback College, and after nearly three decades of building and renovating homes, he applies the same standard to every job: do it right the first time because the second time always costs more. That’s why our crews re-square rough openings, verify flashing, and test every unit before we walk away.

Common Mr-Glass Construction Problems We Solve in Highland
- Seal failure and fogged glass in Mr-Glass 5000 Series vinyl windows. Highland’s summer temperatures regularly push past 100 degrees, and that thermal cycling breaks down window seals faster than coastal climates. We see fogged panes on southwest-facing walls especially, and the fix usually means replacing the insulated glass unit rather than the whole frame.
- Sticking or hard-to-open windows from clay soil movement. Highland sits on expansive clay that swells in wet winters and shrinks in dry summers. That movement shifts rough openings, which binds window sashes and makes Mr-Glass vinyl frames feel stuck. Re-squaring the opening during installation and using proper shims solves it permanently.
- Failed window balances and sagging sashes. The constant heat dries out lubricants and stresses the balance mechanisms on Mr-Glass double-hung and single-hung units. We replace balances with OEM parts on the spot whenever possible so you don’t have to fight a window that won’t stay up.
- Whistling and air leaks during Santa Ana winds. Highland gets hit hard by dry fall winds coming down the Cajon Pass. If a Mr-Glass unit wasn’t flashed and sealed properly at installation, those winds find every gap. We re-flash, re-seal, and often upgrade the weatherstripping to a heavier profile that holds up better against sustained wind.
- Shower door hinge fatigue and glass alignment drift. Older Mr-Glass frameless shower enclosures in Highland homes take a beating from hard water and daily use. We check hinge torque, door sweep alignment, and glass clamp tightness, and when a hinge pivot is worn beyond adjustment we source the correct OEM replacement so the door doesn’t sag into the curb.
Mr-Glass Service in Highland: What Local Conditions Mean for Your Equipment
Here’s the piece of this that a flatland contractor will miss: Highland’s foothill neighborhoods, especially the homes pushing up toward the San Bernardino National Forest along streets like Boulder Avenue, fall under wildland-urban interface fire codes, and our San Bernardino Mr-Glass service team handles these requirements regularly. That means Chapter 7A of the California Building Code applies, and any window or door replacement in those zones must be installed with ember-resistant vents, fire-rated flashing, and ignition-resistant sealing details. There are flatland contractors in the Inland Empire who have never touched a WUI job, and they’ll slap in a replacement window with standard flashing and call it done. It won’t pass inspection. We’ve handled enough WUI-adjacent work in Highland to know exactly what the inspectors look for, including the 1/8-inch mesh vent screens and the specific caulking and flashing products rated for fire exposure. We installed seven warped Mr-Glass 5000 Series vinyl windows in a 1970s ranch on Boulder Avenue once, and after pulling the old frames we found the clay soil had shifted every rough opening slightly. We re-squared each one, then installed new Mr-Glass units with upgraded low-E glass and fire-rated flashing to meet the WUI requirements. The homeowner noticed the difference in street noise the first night.
Mr-Glass Models & Products We Service in Highland
We work on the full line of residential Mr-Glass products, with the most call volume around four families: Mr-Glass 5000 Series Vinyl Windows, Mr-Glass 8000 Series Fiberglass Windows, Mr-Glass Frameless Glass Shower Enclosures, and Mr-Glass Sliding Patio Doors. We keep common hardware like balances, locks, rollers, and hinges stocked for fast turnaround in Highland so you’re not waiting two weeks on a special-order part from a distributor. For glazing, we spec glass packages that make sense for Highland’s climate: low-E coatings for solar heat gain on west-facing walls, and heavier glass thickness on large sliding doors that face the Santa Ana wind path. See our Mr-Glass sales & service page for the full scope of what we handle.

FAQs – Mr-Glass Construction in Highland
Yes, Mr-Glass 5000 Series vinyl windows can meet code in Highland when they’re installed with Chapter 7A-compliant flashing, sealing, and ember-resistant detailing. The window itself is only part of the compliance picture. The installation method, the flashing tape, the caulking, and the vent screens all have to be rated for wildland-urban interface exposure. That’s the part most contractors get wrong. We’ve done enough WUI-adjacent work in Highland to know what passes inspection the first time. Call (855) 473-6535 and we’ll walk your specific home through a compliance checklist.
Almost every time, it’s clay soil movement. Highland’s expansive clay soils absorb water in winter and dry out in summer, which causes the foundation and rough openings to shift slightly. That movement pushes the window frame out of square and binds the sash. The fix is re-squaring the opening during a reinstallation, not just forcing the window open harder or replacing hardware. We diagnose the frame first, then decide whether the fix is shimming, a new sash, or a full replacement.
If the glass panel is cracked, you need to replace that panel. Tempered glass can’t be repaired. The good news is that on most Mr-Glass frameless shower enclosures, a single panel or door can be replaced without tearing out the whole enclosure, as long as the hardware and adjacent panels are still sound. We’ll measure the opening, source the correct glass thickness, and check the hinge and clamp alignment while we’re at it. Call (855) 473-6535 and we’ll tell you exactly what a replacement panel will cost.
Clay soil moves every rough opening slightly over time, so a window that was square in 1985 might be a quarter-inch out of plumb today. If you just swap in a new unit and shim it to the existing opening, you’ve locked in that slight distortion, and the new window will bind and leak eventually. We re-square openings before we install, which adds a little labor but eliminates the binding problem that plagues so many older Highland homes.
A properly installed Mr-Glass vinyl window should last 20 to 25 years in Highland before you’re looking at seal failures and worn balances. Fiberglass units go longer, often 30-plus years. The climate shortens that lifespan compared to coastal areas because the extreme heat cycles stress the sealant and glazing, which is why our Redlands Mr-Glass service crews use installation methods rated for these conditions. If your windows are over 20 years old and starting to fog, stick, or whistle in Santa Ana winds, it’s time to price replacement before the openings get sloppier. Call (855) 473-6535 for a free estimate and we’ll give you an honest read on what’s worth repairing versus replacing.
