We’re Mason Remodeling Co Thousand Oaks, our General Contractor in West Hills, and an independent Mr-Glass service provider working throughout West Hills, CA.

If you own a Mr-Glass enclosure or sliding door in West Hills, call (805) 309-3386 and we’ll come look at it. Estimates are free.
Why West Hills Residents Choose Us for Mr-Glass Service

Mr-Glass has been a fixture in Los Angeles-area homes since before most of West Hills was built out, and we’ve handled the full range of it: 3/8-inch clear tempered frameless panels, 1/2-inch Starphire low-iron glass, Series 600 aluminum sliders, and the mirrored wardrobe doors that went into so many 1960s and 70s custom builds. Isaac Pruett, our owner, grew up in Los Angeles and trained at Los Angeles Trade-Technical College before spending years on job sites across the region. He’s the kind of contractor who calls you back the same day, and his crews bring that same directness to every West Hills job.
We’re independent. We are not manufacturer-affiliated and not an authorized Mr-Glass dealer. That means when we look at a failing seal or a corroded track, we call it straight: replace the part, upgrade the part, or replace the whole unit. No warranty games, no brand loyalty to protect. Our Mr-Glass sales & service work comes with a written price before any work starts, and a written guarantee on the completed job.

Common Mr-Glass Construction Problems We Solve in West Hills
- Silicone seal breakdown on original shower enclosures. The bottom track seals on 1970s Mr-Glass enclosures dry out and crack in West Hills’ hot, dry summers. Water wicks into the curb, and on hillside slabs that already shift with expansive soil, that moisture finds its way into the subfloor. We strip the old seal, dry and treat the curb, and re-seal with a product rated for the temperature swings these bathrooms actually see.
- Patio door roller wear and track corrosion on aluminum sliders. Series 600 Mr-Glass doors from the 1970s and 80s have aluminum tracks that corrode in West Hills’ winter rain runoff and grit up with summer dust. Rollers seize, the door drags, and the frame starts to rack. We replace rollers and channels with upgraded aftermarket components that outlast the originals.
- Hairline cracks at drilled hardware holes in frameless panels. Thermal stress is real here, especially on west-facing bathrooms that bake in afternoon heat. The glass expands, the holes don’t, and cracks start at the hinge or clip points. We see this on 3/8-inch and 1/2-inch clear tempered panels regularly.
- Glass-to-metal contact corrosion at mirror clips and door hinges. Older Mr-Glass mirrored wardrobe doors use metal clips that etch into the tempered surface over time. Once that etching is there, it can’t be polished out. We replace the panel when it’s structural and use isolator gaskets on the new install.
- Undersized 1970s hillside drainage undermining patio door thresholds. South of Victory Boulevard in West Hills, many original homes have drainage systems that were never sized for today’s stormwater flows. Runoff scours fines out from under slabs, the pad settles, and the Mr-Glass door sitting on it no longer squares up. This is a construction repair as much as a glass repair, and we handle both.
Mr-Glass Service in West Hills: What Local Conditions Mean for Your Equipment

West Hills construction work is defined by custom hillside homes on large lots, many built in the 1960s through the 1980s with original structural and drainage systems that are now well past their design assumptions. The clay-heavy, expansive soils in this part of the San Fernando Valley expand in winter and shrink in summer, and the Santa Susana Mountain drainage patterns send runoff down through neighborhoods in ways the original builders didn’t fully plan for. What that means for Mr-Glass owners specifically: a shower enclosure or patio door that was installed square and true in 1978 may now be sitting on a slab that has shifted half an inch or more. Glass doesn’t flex. Frames rack, seals tear, rollers bind. In West Hills, we regularly find Mr-Glass sliding doors that no longer close because the concrete pad they sit on has moved, not because the door itself failed. South of Victory Boulevard, where the original 1970s drainage is undersized for today’s stormwater flows, patio slabs and exterior door thresholds have been undermined for decades. We re-level and re-glaze as part of the construction repair, which is work a glass-only shop won’t do.
One example that sticks with us: our tech pulled a bowed Mr-Glass Series 600 sliding patio door from a 1978 custom home off Platt Avenue, where years of stormwater had washed fines out from under the slab. The rollers were seized and the bottom rail had corroded against the track, so we re-supported the pad, replaced the rollers and weatherstripping, and reset the original tempered glass to slide true again. That’s the difference between patching a symptom and fixing the thing that caused it.
Mr-Glass Models & Products We Service in West Hills
We service the full range of Mr-Glass products found in West Hills homes: the 3/8-inch clear tempered frameless shower enclosure, the 1/2-inch Starphire low-iron glass shower panel, the Series 600 aluminum patio door with single-pane glass, and the custom mirrored wardrobe doors with aluminum frames that went into so many hillside masters. When replacement glass is required, we source factory-spec tempered glass and OEM-style hardware from Mr-Glass distributors. For seals, rollers, and channels, we often install upgraded aftermarket components that handle West Hills’ heat and rain better than the originals ever did. If a panel is cracked or a frame is corroded through, we’ll tell you to replace it, not patch it.

FAQs – Mr-Glass Construction in West Hills
Yes. In most West Hills homes with original 1970s Mr-Glass enclosures, we can rebuild the enclosure using 3/8-inch clear tempered glass that matches the original profile, while replacing the failed seals, hinges, and channels with components that handle the heat and moisture better than the originals. Call (805) 309-3386 and we’ll tell you if your specific enclosure can be rebuilt or if full replacement makes more sense.
It’s usually both. In West Hills, expansive soils and hillside drainage issues cause slabs to shift, and when the pad moves, the Mr-Glass door sitting on it racks and binds. We check the pad level and the drainage path before we touch the door. If the slab has settled, we re-support and level it, then service or replace the door. Call (805) 309-3386 for an assessment.
We do. Those original aluminum-frame Mr-Glass enclosures from the 1970s are all over the hillside neighborhoods of West Hills, and we’ve rebuilt dozens of them. The usual failure is the silicone seal along the bottom track, which lets water into the curb. We strip, dry, and re-seal, and replace any corroded track sections with upgraded aluminum.
Yes. We source 1/2-inch Starphire low-iron glass from Mr-Glass distributors, which gives you that near-colorless edge that makes a frameless panel disappear. We can spec it for a new walk-in shower or match it on a repair where one panel needs replacing. Call (805) 309-3386 for a written quote.
Absolutely. Frameless glass needs a level, square opening or it will stress the hinges and crack over time. On West Hills hillside jobs, we check the floor slope and the curb elevation before any glass is ordered. If the floor needs leveling or the curb needs rebuilding, that’s part of our scope-along with any Bathroom Remodeling - West Hills prep-before the Mr-Glass panel goes in. Tell me what you need done. We’ll tell you what it costs and how long it takes, then we’ll do exactly that. Call (805) 309-3386.
