AfterFast, Reliable Bathroom Remodeling Across Montclair
Bathroom remodeling in Montclair typically runs $9,000 to $28,000 for a full gut-and-replace, with smaller jobs like a tub-to-shower conversion landing between $3,500 and $10,000. The biggest variable isn’t tile choice or fixture grade. It’s what we find when we open the walls of a 1960s tract home: expansive clay slab movement, pre-1980 wiring, and waterproofing that gave up years ago. Barrett & Sons Construction has remodeled bathrooms all over Montclair, and we plan for those discoveries before the first swing of a hammer. Call (877) 610-1318 and we’ll walk you through what your specific house is likely to throw at us.
Why Barrett & Sons Construction Is Montclair’s Preferred Bathroom Remodeling Company
We’re not a franchise dispatching strangers from two counties away. Tom Barrett founded this company in 1998, and his sons run the crews. When you call (877) 610-1318, a live person answers. When we quote a bathroom remodel in Montclair, the scope, the allowances, and every potential change order goes on paper before work starts. That matters here more than most places, because Montclair’s housing stock hides things.
Our Montclair customers tell us the same story: a previous contractor gave a verbal number, opened a wall, found something, and handed over a surprise invoice at the end. We don’t work that way. If we find cloth-wrapped wiring or a slab that heaved after a wet winter, you get a written change order with a fixed price before we touch it. You approve it or you don’t. No surprises.
We serve the 91763 zip code regularly, and our crews know the difference between a bathroom on Ramona Avenue and one on the north side of the 10 - the same local expertise we bring to Fence Installation in Montclair. That local knowledge shapes how we bid the job from day one.
Our Bathroom Remodeling Services in Montclair
Full Bathroom Remodeling
A full bathroom remodel in Montclair means gutting to the studs and rebuilding with modern waterproofing, code-compliant electrical, and fixtures you can actually name. We handle demolition, framing corrections, plumbing rough-in, tile, glass, trim, and final inspection. On a 1950s or 60s home, we expect to find conditions the original builder never accounted for, and our pricing reflects that honestly from the start.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Montclair runs $4,500 to $12,000 depending on size, glass, and what the existing pan looks like when we pull it. We install frameless glass enclosures and engineered substrates that won’t crack when the clay soil under your slab does its seasonal thing. This is the single most requested upgrade from Montclair homeowners who are tired of stepping over a tub edge.
Tub-to-Shower Conversion
Tub-to-shower conversions are our specialty in Montclair’s older homes. The original cast-iron tubs from the 1950s and 60s are heavy, worn, and often sitting on slabs that have moved. We pull the tub, correct the subfloor if needed, and install a level, properly sloped shower pan. Conversions typically run $3,500 to $10,000 here, and we’ll tell you in the estimate whether your slab needs attention first.
Vanities, Tile & Fixtures
Vanity installation in Montclair runs $800 to $3,000, and we work with brands you can look up before you commit. Tile selection, fixture placement, and waterproofing details matter more here than in newer housing stock because the walls move slightly with seasonal moisture swings. We build for that reality, not for a showroom photo.

Trusted Brands We Service in Montclair
We work with premium material brands across every trade, and for Montclair bathroom projects we commonly install Simonton and Ply Gem windows where a bathroom needs new glazing, plus PGT products where impact resistance or thermal performance matters. These aren’t mystery brands off a van. You can look them up, compare specs, and know exactly what you’re paying for before we order anything. Our Bathroom Remodeling team builds with materials that hold up to Pomona Valley heat and the occasional Santa Ana dust blast that finds its way into every poorly sealed opening.
Common Bathroom Remodeling Problems We See in Montclair Homes
- Expansive clay slab heave. Montclair sits on alluvial fan deposits from the San Gabriel Mountains, and the adobe clay under many 1950s to 1970s slabs swells after wet winters. Diagonal wall cracks and a tub that no longer sits level are the telltale signs, and any remodel that ignores them is a cracked shower pan waiting to happen.
- Pre-1980 electrical that fails inspection. Much of Montclair’s original housing stock carries cloth-wrapped or aluminum wiring. The moment we open a wall, code requires bringing exposed circuits up to current standards. A contractor who hides that behind new drywall is creating a future problem and a failed inspection.
- Undersized framing around old tub alcoves. Original 60s-era alcoves were often framed with minimal support, and years of moisture have done damage. We frequently find rotted or undersized studs that need sistering before tile goes up.
- Waterproofing failures at the tub flange and shower pan. Montclair’s hot summers and cooler nights cause thermal cycling that stresses old caulk and grout lines. By the time a homeowner sees peeling paint or a soft floor, water has been working behind the wall for years.

FAQs - Bathroom Remodeling in Montclair
Because Montclair sits on expansive adobe clay from the San Gabriel Mountains alluvial fan, our Driveway & Pavers in Montclair team sees the same soil challenges, and a bathroom remodel that changes any structural condition - a load-bearing wall, a slab cut for a drain line relocation - can trigger a soils report as a permit requirement. Diagonal wall cracks and slab heave on 1960s to 70s homes in the interior tracts are predictable signals that wet winters have reactivated the clay beneath the slab. We pull the permit, we order the soils report when the scope requires it, and we don’t start foundation work until you’ve seen the findings. Call (877) 610-1318 if you have cracks and want an honest read before you commit to a remodel.
A written change order lists exactly what we found, what code requires, the new scope, and the new price. You sign it before we proceed. On a recent Montclair job, we opened a wall and found cloth-wrapped wiring that had to be replaced before drywall could go back. The change order covered the affected circuit, the new Romex, the junction boxes, and the inspection. It was on paper, priced, and approved before we touched the rough-in. No end-of-job surprise.
We inspect the slab first. If it has heaved or cracked, we don’t build a new shower on a moving foundation. We scope the repair - usually cutting out the affected section, correcting the subgrade, and pouring a stable, level substrate - as a written change order before any shower work begins. Then we install the pan and tile on a surface that won’t fail the first wet winter. That’s the only way to do it in Montclair and have the job last.
Yes, any remodel that touches plumbing, electrical, or structural framing needs a permit, and that’s not optional. The permit inspector works for you, not for us, which is exactly why we like having them on the job. We pull permits on every eligible project in Montclair, and we don’t bury old wiring or ignore a cracked slab and call it done. If a previous contractor told you permits were optional, that’s a red flag worth remembering.
On an older Montclair home, we recommend carrying a 10 to 15 percent hidden-conditions allowance for exactly the things this page describes: slab correction, wiring upgrades, and framing repair. It’s written into the contract as a line item, not a blank check. When we find something, it comes out of the allowance with a written change order, and we don’t exceed it without your signature. For an exact number on your specific bathroom, call (877) 610-1318 - estimates are free.
What It Actually Looks Like: A Montclair Field Vignette
We opened a 1963 bathroom near Ramona Avenue and found the original cast-iron tub set into a slab that had heaved ¾ inch at the drain line, plus cloth-wrapped wiring that failed inspection the moment it was exposed. Our crew scoped the subfloor repair as a written change order before touching the rough-in, then replaced the tub with a Kohler walk-in shower on an engineered, level substrate and brought the circuit up to code before inspection sign-off. That’s how we handle every Montclair bathroom we open: honest about what we find, precise about what it costs, and done right before we close the wall.
