Why Vineyard ADU Builders Is Montclair’s Preferred Bathroom Remodeling Company
Montclair’s housing stock is specific. These are small, single-story tract homes built mostly between the late 1940s and the 1970s. We’ve remodeled bathrooms in nearly every corner of the city, from the blocks north of the 10 freeway near Montclair Place to the quieter streets south of Arrow Highway. Homeowners here tend to ask the same question before hiring anyone: how will you handle what’s behind the walls? That’s a fair question, and it’s the one we answer best.
We’re led by Nelson Ibarra, and our team works on Montclair projects regularly. What sets us apart isn’t a slogan. It’s the way we document surprises. When we open a wall and find galvanized lines that should have been replaced decades ago, we photograph it, write up the repair, and get your sign-off before we touch it. That’s how we’ve built our reputation in Montclair – one bathroom at a time.
We’re not a general remodeler who occasionally does bathrooms. Bathrooms are one of our three core trades, alongside kitchen remodeling and ADU construction. That focus means our crews know exactly what mid-century Montclair homes hold. We don’t guess. We’ve seen it.
Our Bathroom Remodeling Services in Montclair
Full Bathroom Gut Renovations
When we gut a bathroom in Montclair, we start with the assumption that the original 1960s plumbing and wiring will need attention. That assumption goes into the quote. We remove down to the studs, address any framing or waterproofing failures we find, and rebuild with a properly sloped shower pan, cement board, and a waterproofing membrane that won’t fail the way 1970s lead pans did. Most full renovations in Montclair run $18,000 to $42,000 depending on size and finish level.
Shower and Tub Replacements
Many Montclair homes still have the original cast-iron tub or a one-piece fiberglass shower stall. Replacing either means opening the walls around it, and that’s where old venting and supply lines get exposed. We quote the replacement and the likely plumbing work together, so you’re not hit with a second number after demolition. A tub-to-shower conversion in Montclair usually runs $7,500 to $14,000.
Bathroom Accessibility Upgrades
Montclair has a large number of longtime homeowners who plan to age in place. We install curbless showers, grab bars anchored into blocking, wider door openings, and comfort-height toilets. On a small 1950s bathroom, these changes require careful planning because the original footprint is tight. We’ve done it often enough to know how to gain three inches here and four inches there without moving walls unnecessarily.
Vanity, Flooring, and Finish Work
Sometimes the bones of the bathroom are fine and the problem is the 1980s oak vanity, the sheet vinyl, and a medicine cabinet that’s seen better decades. We handle these projects too. We can match the style of your Montclair home – clean lines, simple tile work, not overly ornate – while updating materials to what’s actually durable today. Expect $9,500 to $18,000 for a full finish-level remodel without moving plumbing.

Common Bathroom Remodeling Problems We See in Montclair Homes
Montclair’s tract homes share a family tree. Same builders, same era, same problems. Here’s what we find most often:
- Failed lead shower pans from the 1970s. The pan rots underneath the tile layer, and you only discover it after demolition. We always budget for pan replacement on any home from this era.
- Undersized or ungrounded bathroom wiring. Adding a GFCI outlet or a heated element often reveals the circuit can’t support it. The fix may be a small panel upgrade, which we quote and approve before proceeding.
- Improperly vented exhaust fans. Decades of Montclair remodels sent bathroom fans into the attic or soffit, not outside. That causes mold. Bringing the vent to current code is a common finding.
- Original galvanized supply lines. These rust from the inside. Flow drops. When we replace them with PEX, water pressure in the shower often improves dramatically on the same old valve.
The Montclair Venting Issue Most Remodelers Don’t Mention Up Front
Here’s the thing about Montclair specifically. The post-war tract homes in this city often had bathroom plumbing vents run through the roof or tied into an interior wall. When walls open for a remodel, those vents frequently don’t meet current California Plumbing Code. They’re too small, or they were never properly tied in. The code upgrade is mandatory. It wasn’t in your original quote from anyone who didn’t know these houses. We know these houses, so we build that allowance into our estimate from day one. That’s the difference between a contractor who’s remodeled Montclair bathrooms and one who hasn’t.
On a recent remodel in the 91763 ZIP code near the Montclair Plaza area, our crew opened the wall behind the vanity and found the original 1960s galvanized supply lines had been patched with copper in a way that restricted flow, plus the drain was tied into an undersized cast-iron line. We wrote up the repair with photos the same day, got the homeowner’s approval on a change order, and replaced the lines with PEX before setting the new tile – avoiding a mid-project stall that would have added weeks.
Pricing for Bathroom Remodeling in Montclair, CA

Call (855) 382-8121 for an exact quote – estimates are free.
We photograph the issue, write up the repair with a fixed price, and get your approval in writing before we do the work. You never walk in to find we’ve done $4,000 of unapproved work. That’s how we’ve worked in Montclair since day one, and it’s the main reason homeowners refer us to neighbors.
Yes, any remodel that moves plumbing, replaces a shower pan, or alters electrical requires a permit through the City of Montclair. Code upgrades are usually triggered by venting that doesn’t meet current California Plumbing Code, ungrounded wiring, or a shower pan that fails waterproofing standards. We pull the permits and schedule inspections ourselves. Call (855) 382-8121 and we’ll tell you what your specific project will trigger.
We hang plastic containment barriers, use negative air fans when needed, and run floor protection from the entry to the bathroom. In Montclair’s smaller homes, where the bathroom often sits right off a hallway or the main bedroom, dust control is non-negotiable. We clean up daily and do a final deep clean before we walk the project with you.
Yes. We’re familiar with the clean, simple aesthetics of Montclair’s post-war tract homes. We can keep the character – simple tile patterns, period-appropriate colors if you want them, unfussy fixtures – while upgrading the waterproofing, venting, and electrical to current standards. The goal is a bathroom that looks like it belongs in your house but works like new construction.
