Mr-Glass Construction in Poway, CA | Mason Remodeling Co San Diego
We’re Mason Remodeling Co San Diego, your Poway General Contractor, and we provide independent Mr-Glass service across the area. We service and install Mr-Glass shower enclosures, glass shelving, and mirror systems without being manufacturer-authorized, which means we’re free to match parts and recommend fixes that actually fit your home, not just the product catalog. What makes our Mr-Glass work different in Poway is simple: we’ve spent years repairing this brand inside the city’s specific housing stock, and we know exactly what its glass does when a 1979 tract home shifts during shear-wall retrofits or hard Poway well water etches a clear panel over a decade. Call (619) 673-9302 for service.
Why Poway Residents Choose Us for Mr-Glass Service
Poway homes are not like the newer builds down in San Diego proper. The majority of the city’s single-family detached homes went up in the 1970s and 1980s, wood-framed on concrete slabs, and a lot of them still carry original Mr-Glass enclosures from the first remodel. We’ve worked inside those bathrooms. We know how the framing tolerances on a 1981 tract home off Twin Peaks Road differ from a custom equestrian property out east, and we account for that before we touch a single screw. Isaac Pruett, who runs our Poway work, grew up swinging a framing hammer in Los Angeles and sharpened his eye for out-of-square walls long before he ever saw a Mr-Glass track. The man still keeps his apprenticeship notes in the truck. That’s the kind of detail we bring to every enclosure we hang. We’re local to Poway’s conditions, we stock the rollers, hinges, sweeps, and side channels Mr-Glass systems actually need, and we show up with the right parts the first time. This is Mr-Glass sales & service done by people who have pulled the permit, opened the wall, and seen what’s behind it.

Common Mr-Glass Construction Problems We Solve in Poway
- Mineral-etched glass from hard well water. Poway’s water is hard enough to leave visible etching on Mr-Glass clear panels within a decade. The glass gets cloudy, then rough, then impossible to clean. We quote glass replacement honestly, and often it’s cheaper long-term than trying to polish out years of mineral damage.
- Out-of-square shower openings cracking side channels. Original 1970s and ’80s Poway shower openings rarely measure square anymore. When a Mr-Glass frame gets forced into a crooked opening, the aluminum side channels take the stress, and we regularly see hairline cracks at the curb corners. We shim the frame to true before anything else.
- UV and wind-driven dust degrading vinyl sweeps and pivot hinges. Poway’s hot, dry summers and Santa Ana winds punish exterior glass inserts. Mr-Glass vinyl sweeps turn brittle, pivot hinges grind with dust, and the door starts leaking air. We replace the hardware with matched aftermarket or genuine Mr-Glass parts, depending on what the seal demands.
- Bottom tracks popping out of level on pre-1990 slabs. Minor soil settlement in older Poway slab foundations moves shower drains and floors by fractions of an inch. That’s enough to knock a Mr-Glass bottom track out of level and make rollers jam. We reset the track on a level bed rather than just adjusting the doors and hoping.
- Stress cracks at curb corners from repeated forced alignment. The combination of out-of-square openings and Poway’s thermal expansion cycles means Mr-Glass corner joints take a beating over 30-plus years. We’ve fixed enough of them to know when a corner is salvageable and when the whole channel set needs replacement.
Mr-Glass Service in Poway: What Local Conditions Mean for Your Equipment
Here’s the thing most glass companies won’t tell you about Poway: east of Espola Road, the original 1970s and ’80s tract homes routinely trigger mandatory shear-wall upgrades the moment a homeowner pulls a re-roof or addition permit. When those walls get reframed, the plumbing chases running through them shift just enough to crack Mr-Glass shower seals and corner joints in ways you’d almost never see in a newer Rancho Peñasquitos build or a Coronado beach bungalow. On Carriage Road just east of Espola, our crew pulled a re-roof permit that triggered exactly that: shear-wall retrofits on a 1979 tract home. During wall reframing, the original Mr-Glass Classic sliding enclosure dropped out of square. We reinstalled it with a new bottom track, white side channels, and shimmed curb corners so the doors rolled clean and sealed tight, with no re-permit needed on the glass. That’s the difference between a crew that reads the permit landscape and one that just swaps hardware. In Poway, the wall and the glass are never separate problems.
Mr-Glass Models & Products We Service in Poway
Our crews work on the Mr-Glass Classic Series sliding shower enclosures, the Premium Frameless Series, Neo-Angle shower units, and custom glass shelving and mirror systems. We match Mr-Glass hardware with OEM-like rollers, hinges, and sweeps from proven aftermarket suppliers when the fit is standard, and we use genuine Mr-Glass branded parts in the cases where seals or finish colors must match exactly. For Poway homeowners with etched or cracked panels, we give you a straight repair-versus-replace quote, and on hard water, full panel replacement usually wins on cost over time. We keep the most common Poway-failure parts in local stock so a service call doesn’t turn into a two-week parts wait.

AfterMr-Glass Service Pricing in Poway

Mr-Glass work in Poway spans a few common project types, and the price depends on the condition of the original framing you’re working inside. Our independent service means we quote the work itself, not a brand premium.
| Service | Price Range |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Frameless Glass Shower Enclosure (Mr-Glass retrofit) | $4,500 – $12,000 |
What drives the cost here is what we find when we open the wall: crooked framing, shifted plumbing chases, dry rot at the curb. Your free estimate includes a written, line-item price before any work starts, never a verbal ballpark that grows at the final invoice. Call (619) 673-9302 and we’ll come look at the actual opening, not a photo of it.

FAQs – Mr-Glass Construction in Poway
Yes, panel replacement is usually the right call on Poway water. Hard well water etches glass in a way that can’t be polished out, and replacing just the panels costs less than a full enclosure rebuild, around $500 to $1,600 per panel depending on size and hardware match. But if your frame is also cracked or out of square, we’ll tell you before you spend on glass alone. Call (619) 673-9302 for a free estimate.
We can. On Poway’s larger custom builds from the 1980s, we regularly see bronze and gold Mr-Glass hardware that’s no longer in the standard catalog. We match the finish through genuine Mr-Glass parts when available, and when they’re not, we source aftermarket equivalents that a careful eye can’t distinguish. We’ll show you the sample before anything gets drilled.
In Poway, it’s usually both. On pre-1990 slabs, minor settlement pulls the track out of level, and the original opening is often out of square on top of that. We check the wall first, shim the frame back to true, then reset the track on a level bed. Just replacing rollers without fixing the wall is a six-month fix, not the real one.
Shower glass itself isn’t a fire-rated assembly, but we do check the surrounding wall penetrations when we work on hillside Poway homes in the wildland-urban interface. Fire-resistive detailing around plumbing chases matters, and any gap we open stays properly sealed when we close it. Your Mr-Glass frame isn’t the fire problem, the gaps around it can be.
Most Bathroom Remodeling - Poway tub-to-shower conversions where shear-wall work is involved run one to two weeks from demo to final seal, including any required inspections. If the wall reframing is already done from a prior re-roof permit, the glass portion itself can go in as fast as two to three days. We’ll give you a written timeline before the first tool comes off the truck, and if the permit requires something extra, it’s in the upfront price, not a surprise on the back end.
