Why West Covina Homeowners Choose Mr-Glass Construction
We provide Mr Glass service in West Covina, including frameless shower enclosures, tub-to-shower conversions, and walk-in shower installations. Our crew has worked on hundreds of Mr-Glass enclosures across Southern California, and we know the hard-water damage patterns and installation quirks that show up in West Covina’s 1950s-to-1980s housing stock better than any factory hotline. We are not affiliated with or authorized by Mr-Glass. We are an independent service provider that repairs and installs their products because they are genuinely well-built glass systems, and because West Covina homeowners keep asking for them. Call (707) 760-7579 for a free estimate on any Mr-Glass project.
Why Trust Mason Remodeling Co West Covina for Your Mr-Glass Construction?
Isaac Pruett, General Contractor and owner of Mason Remodeling Co West Covina, learned the trade through the construction technology program at Los Angeles Trade-Technical College and spent decades swinging hammers on real jobs across the San Gabriel Valley. He and his crew have worked throughout West Covina for years, including projects near Eastland Center where older homes needed everything from foundation repairs to full kitchen overhauls. That experience matters when you are dealing with a Mr-Glass enclosure installed in a bathroom that was originally framed in 1962. We know how post-tensioned slabs and original wood framing affect glass alignment. We know which rollers wear out first on Mr-Glass sliding doors. And we know that a shower door that will not close is not a minor annoyance. It is a daily frustration and a water-damage risk. Our technicians are background-checked and identity-verified under the Threshold Standard, which means you get a name and photo before we arrive, and a photo ID badge at the door. Plus, every project gets a written price before work starts, covered by our 365-Day Done Right Promise. If the work is not right within a year of completion, we make it right at no cost. You should know what you’re getting before we ever pick up a tool.

Common Mr-Glass Construction Problems We Fix in West Covina
- Sagging or misaligned Mr-Glass sliding doors. On the Mr-Glass Sliding/By-Pass series, the nylon rollers inside the top track wear flat over time. Once that happens, the door drops slightly and starts dragging or catching. In West Covina homes with original framing on hillside lots, even a sixteenth of an inch of settling makes the misalignment worse. We replace the roller kits and re-hang the panel so the gap is even from top to bottom.
- Hard-water mineral buildup etching Mr-Glass clear panels. West Covina’s municipal water is hard. Calcium and magnesium deposits build up on 3/8-inch and 1/2-inch Mr-Glass clear glass panels, especially near the lower corners where water sits. Left long enough, mineral etching becomes permanent. We remove surface buildup with glass-safe compounds and advise on sealing and maintenance routines that slow the damage. If a panel is already etched beyond restoration, we say so plainly and quote a replacement rather than promising a miracle cleanup.
- Silicone seal failure at the threshold or curb. The original sealant on any Mr-Glass enclosure eventually dries, cracks, or pulls away from the tile. Water then seeps behind the wall or under the curb. This is the most common leak point we see in West Covina bathrooms. We cut out the old silicone, clean the joint, and re-seal with mildew-resistant silicone rated for wet areas. If water has already gotten behind the wall, we check for rot or mold before closing anything back up.
- Glass panel flexing and cracking at hinge points. On Mr-Glass Frameless Series and Neo-Angle enclosures, the glass panels are heavy. If the original installer did not shim the panel correctly, or if the wall it is anchored to has shifted over decades, the glass flexes at the hinge and eventually cracks or chips. We inspect the mounting points, correct the shimming, and replace hardware before it fails. Catching this early is the difference between a $400 hinge repair and a $2,000 panel replacement.
- Corroded aluminum hardware from hard water and humidity. Mr-Glass’s standard aluminum hinges, handles, and towel bars hold up well in normal conditions, but West Covina’s hard water and the humidity from a daily shower routine accelerate corrosion. We see pitted hinges and seized set screws on enclosures that are only five or six years old. We replace with genuine Mr-Glass hardware when available, or quality aftermarket equivalents tested for the same weight ratings when the factory part is discontinued.
Mr-Glass Parts & Our Repair-vs-Replace Approach
We source genuine Mr-Glass hardware whenever it is available. Roller kits, hinges, handles, and seals from the factory are our first choice because they match the original engineering spec. But Mr-Glass has discontinued certain hardware lines over the years, and backordered parts can leave a shower door hanging for weeks. When that happens, we use high-quality aftermarket equivalents tested for the same weight ratings and finish durability. We are upfront about which one you are getting, and we put it in writing. We only recommend full replacement when the glass itself is delaminating, cracked, or pitted beyond restoration. Otherwise, we repair the mechanism and re-seal the enclosure. A worn roller or a failed silicone seal does not mean you need a new $3,000 enclosure. It means you need the right $80 part installed correctly. Call (707) 760-7579 if you want an honest assessment of what your Mr-Glass enclosure actually needs.
Our Mr-Glass Service Process – Step by Step
- 1
Diagnosis. We inspect the enclosure, check the glass, the track, the rollers, the hinges, and the silicone seals. We identify the specific failure point and what caused it. For sliding doors, we check the top track alignment against the original framing. For frameless panels, we check for flex at the hinge points and any signs of water intrusion behind the wall.
- 2
Written quote. Before any work starts, you get a written price. It covers parts and labor in one number. No verbal estimate that grows on the final bill. If the job exposes a hidden problem after we start, we stop and tell you before spending another dollar.
- 3
Repair or installation. We remove failed hardware, install the new rollers, hinges, or seals, and align the glass. For new Mr-Glass enclosures and tub-to-shower conversions, we handle the full installation including plumbing adjustments, waterproofing, tile work, and glass panel setting. Every crew member arrives in a clean marked uniform with a photo ID badge.
- 4
Testing. We run water through the enclosure, check every seam for leaks, open and close the door repeatedly, and inspect the alignment. We do not leave until the door operates smoothly and the enclosure is watertight.
- 5
Warranty coverage. Every completed project is covered by our 365-Day Done Right Promise. If something is not right within a year of completion, we return and make it right at no cost. The terms are in writing, including what is covered and for how long.

FAQs – Mr-Glass Construction Service in West Covina
No. We are an independent Mr-Glass service provider. We are not affiliated with or authorized by Mr-Glass. We service their products because they are well-engineered glass systems, and because West Covina homeowners keep asking us to fix and install them.
Yes, whenever genuine Mr-Glass hardware is available. We source factory rollers, hinges, and handles as our first choice. If a part is discontinued or backordered, we use a high-quality aftermarket equivalent tested for the same weight ratings and finish. We tell you which one you are getting before we install it. Call (707) 760-7579 for an exact quote on your enclosure repair.
Yes, this is one of the most common repairs we do in West Covina. A Mr-Glass sliding door comes off its top track when the rollers wear flat and the panel drops. We source a matching roller kit, re-hang the glass, and re-seal the curb if needed. In most cases the enclosure does not need replacement. Call (707) 760-7579 and we will assess it in person.
We remove surface mineral buildup with glass-safe compounds and then recommend a maintenance routine to slow future etching. If the glass is already permanently etched or pitted, we will tell you straight, because no cleaner will reverse it. In that case, we quote a panel replacement rather than a cosmetic fix.
Yes. We convert tubs to walk-in Mr-Glass showers in bathrooms as small as 5 feet by 8 feet. The key is using a low-profile threshold and a frameless panel layout that works with the existing footprint. We measure the exact opening, account for the door swing, and use Mr-Glass 3/8-inch frameless panels to keep the space open. A tub-to-shower conversion in West Covina typically runs $3,500 to $10,000. Call (707) 760-7579 for a written quote on your bathroom.
Water leaking from the bottom corners almost always means the silicone seal at the threshold or curb has failed. The original sealant dries out, cracks, or pulls away from the tile, and water finds the gap. We cut out the old sealant, clean the joint, and re-seal with mildew-resistant silicone rated for wet areas. If water has been leaking for a while, we also check for rot or mold behind the wall before closing the joint back up. Call (707) 760-7579 to schedule a diagnosis.
