Mr-Glass Construction in Crestline, CA | San Mateo Construction
We provide independent Mr-Glass service across Crestline, from shower enclosures to custom mirrors, and the thing that separates our work here is simple: we know what 4,600 feet of elevation, freeze-thaw cycles, and sloped pier-and-beam foundations do to glass and the walls holding it. We also offer Mr-Glass in San Bernardino and nearby communities. San Mateo Construction installs and repairs Mr-Glass frameless and semi-frameless enclosures throughout the 92325 ZIP, with an approach built around how Crestline cabins actually sit and shift. If your shower door is dragging, leaking at the curb, or the glass looks fogged from mountain minerals, call (855) 901-7266 and we’ll tell you whether it’s a hinge fix or a full replacement.
Why Crestline Residents Choose Us for Mr-Glass Service
Most glass crews in the valley below don’t think about what a hard Crestline winter does to a pivot hinge. We do, because we’ve been correcting it for years. Mr-Glass ¾-inch and ⅜-inch frameless enclosures are well-built glass, but the hardware and seals take a beating up here. Noel Carrington, our owner, grew up pouring footings with his father in the Baywood neighborhood of San Mateo and has spent decades on residential jobs where the frame is never perfectly square. That background matters on a mountain lot, where one wall can be out of plumb by half an inch and the glass still has to seal tight. We stock OEM-style Mr-Glass hinges, sweeps, and seals that match existing door patterns, so when the frame and glass are sound we can usually repair rather than replace. Tell me what you actually need, and we’ll figure out the right way to build it.

Common Mr-Glass Construction Problems We Solve in Crestline
- Freeze-thaw hinge sag on frameless doors. Crestline winters cycle through hard freezes and snowmelt, and those temperature swings loosen the pivot hinges and sweep seals on Mr-Glass frameless doors. The door starts sagging, then drags on the sill and chips the glass edge. We re-set hinges, re-shim the curb, and install replacement seals.
- Panels out of plumb on pier-and-beam cabins. Many older Crestline homes sit on sloped lots with pier-and-beam foundations that settle unevenly over decades. A Mr-Glass panel installed to a wall that’s drifted out of square pulls the gasket away from the curb, and water leaks into the subfloor. We measure the actual opening, trim or shim as needed, and seal with a silicone rated for freeze-thaw.
- Frame corrosion from moisture-retaining cabins. Pre-2007 wood-sided cabins around Crestline hold moisture longer than stucco homes in the valley. Chrome and aluminum frames on older Mr-Glass units pit and corrode faster as a result, especially near the bottom track where water sits. We review the frame condition during any service call and tell you honestly if the glass is worth saving.
- Fogging and mineral etching from snow-melt water intrusion. Snow load and ice dams near bathroom remodels push water into places it shouldn’t go. That intrusion shows up on installed Mr-Glass panels as persistent fogging between panes or mineral etching from hard-water runoff. Sometimes the panel can be cleaned and re-sealed; other times replacement is the only way to get clear glass back.
- Doors that never fit right after a quick valley-style install. A Mr-Glass enclosure measured to valley floor conventions rarely fits a Crestline cabin opening. We see doors that were installed square to a wall that wasn’t, and the homeowner has been living with a gap at the corner for years. Our team measures everything on-site at elevation and cuts to the actual opening.
Mr-Glass Service in Crestline: What Local Conditions Mean for Your Equipment
Because almost no Crestline lot has flat staging, Mr-Glass panels and mirror glass often arrive by pickup or hand-carry up sloped, narrow driveways, and we cut and measure on-site at over 4,600 feet rather than ordering pre-cut stock. Cabin openings up here rarely match valley specs, and a panel that was factory-cut to a “standard” 60-inch opening will be off by half an inch on a 1950s pier-and-beam cabin wall. That half-inch is the difference between a gasket that seals and one that leaks into the subfloor every time someone showers. We’ve worked on mid-century cabins off the narrow streets above Lake Gregory where the driveway is steep enough that a panel truck can’t safely stage at the door, so the glass comes up by hand with edge guards and moving blankets. That’s not a complaint; it’s just how glass work gets done correctly in Crestline.
On one mid-century pier-and-beam cabin off a narrow Crestline street, our crew pulled a sagging Mr-Glass frameless shower door whose hinges had loosened after a hard freeze and re-set it on a re-shimmed curb, then installed a new ⅜-inch Mr-Glass enclosure with a low-profile sweep to stop the leak into the subfloor. We found the wall was out of plumb by over half an inch, so we mocked up the glass, trimmed the opening, and sealed it with a mountain-rated silicone that holds through freeze-thaw. That job was less about the glass and more about the framing behind it.
Mr-Glass Models & Products We Service in Crestline
We work on the full Mr-Glass residential line: ¾-inch and ⅜-inch frameless shower enclosures, semi-frameless shower doors, sliding and bypass doors, and custom mirror and vanity glass. When the frame and glass are still sound, we match the existing Mr-Glass thickness and hinge pattern and source OEM-style replacement hinges, sweeps, and seals. When the glass is chipped, etched from hard-water or snow-melt minerals, or the enclosure was built to a discontinued pattern, we recommend a full replacement rather than chasing parts. It’s usually the more honest call in a Crestline cabin, where a repair that fails six months later means water in a subfloor that already fights moisture every winter.

AfterMr-Glass Service Pricing in Crestline
Most Mr-Glass work in Crestline falls into one of the ranges below. The honest variables are wall squareness, access, and whether the existing frame and glass can be reused.

|---|---|
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Shower Replacement | $3,000 – $8,500 |
| Roof Repair (related water intrusion work) | $400 – $1,800 |

FAQs – Mr-Glass Construction in Crestline
Rarely without modification. Standard Mr-Glass panels assume a nearly square opening, and Crestline cabins on pier-and-beam foundations are often out of plumb by half an inch or more after decades of settling and freeze-thaw cycles. We measure the actual opening, mock up the glass, and trim or shim the curb and walls so the gasket seals tight against the real wall, not the one the manufacturer drew in a spec sheet. Call (855) 901-7266 for an exact measurement visit.
The freeze-thaw cycles in Crestline loosen the pivot hinges on frameless Mr-Glass doors, which lets the door sag just enough to drag on the sill and chip the glass edge. It’s the single most common winter-related call we get in the 92325 area. We re-set the hinges, re-shim the curb if the floor has shifted, and replace the sweep seal so the door swings without binding.
Yes, but usually indirectly. Current Crestline wildfire code drives exterior materials and venting, not interior shower glass, but any remodel that touches exterior walls, vents, or roof penetrations near a bathroom must meet ignition-resistant standards. If your Mr-Glass project is part of a larger bathroom remodel, we coordinate the waterproofing and venting details so the whole job passes inspection without holding up the glass work.
Yes, and we plan for it from the first visit. Most Crestline lots have no flat staging, so Mr-Glass panels and mirror glass come up by pickup or hand-carry with edge guards and moving blankets. The same careful approach applies to our Highland Mr-Glass service. We cut and measure on-site rather than assuming a valley-standard opening, because cabin openings rarely match pre-cut stock. If access is particularly tight, we’ll tell you before the glass is ordered, not after.
Repair makes sense when the glass is clear and the frame is intact, and the problem is a hinge, sweep, or seal. Replacement makes sense when the glass is chipped, etched from hard-water or snow-melt minerals, or the enclosure was built to a discontinued Mr-Glass pattern. Chasing parts on a discontinued pattern usually costs more in labor than a new enclosure, and we’d rather tell you that upfront. Call (855) 901-7266 and we’ll give you an honest read.
