Fast, Reliable Bathroom Remodeling Across Montclair
Bathroom remodeling in Montclair typically runs $18,000 – $38,000 for a full gut renovation of a standard 5’x8′ hall bath, with most projects taking three to five weeks once permits are issued. That range reflects what we consistently see in the 91763 corridor, where homes built between the 1950s and 1970s carry specific plumbing and electrical conditions that newer cities don’t. If you’re planning a remodel in Montclair, call (844) 386-2399 for a free, written estimate that accounts for what’s actually behind your walls, not just what you can see.
Why Orchard ADU Builders Is Montclair’s Preferred Bathroom Remodeling Company
We’ve spent enough time inside Montclair’s post-war tract homes to know exactly what a remodel here involves. The stucco exteriors and original floor plans are familiar territory for our crews. When we walk into a 1963 ranch on a quiet street off Holt Boulevard, we already know what the plumbing stack probably looks like, how the original tile was set, and where the electrical panel is hiding. That familiarity means our inspection-first process catches problems before demolition, not after.
Homeowners across Montclair have worked with our Bathroom Remodeling team for full remodels, waterproofing repairs, and code upgrades. Allen Prescott, who leads Orchard ADU Builders, set the standard early: every surprise gets documented, priced, and approved in writing before we touch it. No verbal change orders. No mid-project ambiguity. Montclair homeowners tell us that’s the difference between a remodel they’d recommend and one they’d rather forget.
We also bring something unusual to a bathroom remodel: our primary work is ADU construction. That means we think about plumbing runs, panel capacity, and waterproofing the way a builder does, not just a finish contractor. When you need a bathroom remodel that might eventually connect to a future ADU or garage conversion, we’re already planning for it. Call (844) 386-2399 to talk through your project.
Our Bathroom Remodeling Services in Montclair
Full Bathroom Remodel with Inspection-First Process
Every full remodel in Montclair starts with a thorough inspection of what’s behind the tile, under the floor, and inside the walls. We’re not just looking at design choices on day one. We’re checking galvanized supply lines, drain slope, stud condition, and electrical grounding. In a 1960s home off Ramona Avenue, that inspection is what protects your budget. We write allowances into the contract for the typical Montclair conditions, so when we open a wall and find what we expected, it’s already accounted for.
Waterproofing and Substrate Replacement
Montclair’s older bathrooms were built with tar-paper waterproofing behind tile, a method that fails after 40 to 60 years. Once that barrier breaks down, moisture moves into the wood framing and subfloor. By the time a homeowner notices cracking grout or a soft spot near the tub, the damage is already behind the tile. We replace failed substrate with cement board, apply modern waterproof membranes, and rebuild the shower or tub surround to current code. James Hardie cement board is our standard for wet areas because it holds up to Montclair’s dry heat without warping or swelling.
Electrical and Plumbing Code Upgrades
A permit inspection in Montclair will flag ungrounded wiring, missing GFCI protection, or an undersized panel. These aren’t optional fixes. The bathroom can’t pass final inspection until they’re resolved. We handle the upgrades directly rather than sending you to subcontractors you never met. Our team replaces galvanized supply lines with PEX, swaps out corroded copper drains for ABS, and rewires circuits to code. It’s part of the remodel, not an add-on bid from a third party.
Layout-Match Remodels for Existing Floor Plans
If you want to keep the toilet, sink, and tub in their current positions, we can do that. Matching the existing layout avoids relocating drain lines and supply pipes, which is one of the most expensive parts of any bathroom remodel in Montclair. The savings can run $3,000 – $6,000 on a typical hall bath. We’ll show you exactly where the money goes in the written estimate.

Trusted Brands We Service in Montclair
We’re brand-agnostic, which means we recommend materials based on what works in Montclair’s climate and housing stock, not what we’re contractually obligated to sell. For bathroom remodels, that often means James Hardie cement board behind tile and around tub surrounds. The product resists moisture and termites, and it doesn’t fail the way old gypsum and tar-paper assemblies do. For homeowners also planning an ADU or garage conversion, we can coordinate the bathroom remodel with a Tuff Shed shell conversion or a Plant Prefab unit, since we build with both platforms. That means one contractor relationship for the interior work and the new unit, not two separate crews with two separate timelines.
Common Bathroom Remodeling Problems We See in Montclair Homes
Homes along the 91763 corridor share a building era, and that era has specific failure modes. Here’s what we find most often when we open walls in Montclair:
- Galvanized supply lines that fail pressure tests. Original steel pipes corrode from the inside, reducing flow to a trickle. Once walls are open and the system is tested, a whole-bath repipe becomes mandatory. We write this allowance into the contract from day one.
- Scaled copper drains that won’t clear. We’ve pulled copper drain lines with 60% of the interior diameter gone, coated in mineral scale. Snaking won’t fix it. The line gets replaced with ABS while the walls are already open.
- Failed tar-paper waterproofing and hidden mold. The original waterproofing behind Montclair’s 1960s tile was never designed to last this long. We remove the tile, find wet substrate, and replace it with cement board and a modern membrane.
- Ungrounded wiring and missing GFCI protection. Montclair’s older homes often still have original two-prong circuits. The final inspection requires grounded, GFCI-protected outlets within six feet of water. If the panel can’t handle the load, we upgrade it.
Pricing for Bathroom Remodeling in Montclair, CA
A standard full bathroom remodel in Montclair runs $18,000 – $38,000 depending on the house’s condition and the finishes you choose. Here’s how that breaks down in today’s market:

- Full remodel with layout unchanged (tub or shower replacement, new tile, new vanity, new lighting): $18,000 – $28,000

The big variable in Montclair is what’s behind the walls. Homes in Montclair built before 1980 almost always need plumbing work once walls open. That’s not a scare tactic. It’s the reality of 60-year-old galvanized steel in a city with hard water. Call (844) 386-2399 for a written line-item estimate. It’s free, and it shows exactly where your money goes before you sign anything.
On a 1962 stucco tract home near Holt Boulevard, our crew opened the hall bath to find galvanized supply lines with less than 40% flow and a copper drain line scaled shut. We replaced the entire wet wall with PEX and ABS, added a layer of James Hardie cement board behind the tile, and rewired the GFCI circuit. Every part of that work was priced and approved in writing before demolition continued. That’s how we handle every Montclair remodel. The surprise gets a number, the number gets your signature, and only then does the work proceed.

FAQs – Bathroom Remodeling in Montclair
Any bathroom remodel that moves plumbing, changes electrical circuits, or opens walls for structural work requires a permit from the City of Montclair. Yes, the inspection will likely trigger upgrades if your home still has original galvanized plumbing or ungrounded wiring. Those upgrades are not optional if you want to pass final inspection. We include the likely upgrades in our initial estimate so the permit stage doesn’t turn into a surprise. Call (844) 386-2399 and we’ll tell you what your specific house will likely need.
The most common surprise is failed galvanized supply lines and scaled copper drains. Homes in the 91763 corridor were built before PEX and ABS became standard, and the original pipes are now 50 to 60 years old. Once walls open and the system is pressure-tested, a whole-bath repipe is often required. We write a plumbing allowance into every Montclair contract to cover this, so it’s not a surprise to us, and it won’t be one to you either. Call (844) 386-2399 for an estimate that accounts for it from the start.
Every unexpected repair gets documented with a written change order, a specific price, and your approval before we proceed. We don’t do verbal agreements, and we don’t keep working while you’re still deciding. The change order shows the exact work, the exact cost, and how it affects the timeline. You sign it, we do it. If you don’t want to do it, we discuss alternatives. Call (844) 386-2399 and we’ll explain the process in detail before you ever sign a contract.
Yes, and in Montclair this is often the smartest choice. Keeping the toilet, sink, and tub in their current positions avoids moving drain lines and supply pipes, which is expensive work in a post-war slab foundation home. You save $3,000 – $6,000 on a typical hall bath by keeping the footprint. You can still upgrade every fixture, tile surface, and finish. The savings come from the plumbing, not what you see. Call (844) 386-2399 to discuss whether your layout is worth keeping.
We offer a structured payment schedule tied to project milestones, so you’re never paying for work that hasn’t happened yet. For larger remodels that include an ADU or garage conversion, we can discuss financing options with your lender or point you toward local credit unions that work with Montclair homeowners on renovation loans. The estimate is free, so you’ll know the total before you make any financing decisions. Call (844) 386-2399 to start with the free written estimate.
