Why Fullerton ADU Builders Is Claremont’s Preferred Bathroom Remodeling Company
Claremont’s homes are special but they’re also old. Most of what we remodel here was built between the 1920s and the 1960s, which means every bathroom project carries a layer of unknowns that a newer tract home simply doesn’t. Our Bathroom Remodeling team has spent years navigating exactly this: cloth-insulated wiring, rotted sill plates behind tub surrounds, and cast-iron drain lines that haven’t been touched since Eisenhower was president. We’re not a marketing company that subs out the work. We show up, we open the walls, and we handle what’s actually there.
Led by Glen Pacheco, we’ve built a local reputation in Claremont as the contractor who doesn’t flinch at what demo reveals. That matters more than any review count I could quote. Homeowners along Foothill Boulevard and in the tree-lined streets near Memorial Park have called us back for second and third projects, not because we’re the cheapest, but because our numbers hold. We write allowances into the contract for the upgrades we suspect are coming, and we never spring a cost on you after the tile is ordered. Response time to Claremont is typically a same-week estimate visit, with a written line-item quote within 72 hours.
Being based in Fullerton means we’re close enough to Claremont that scheduling doesn’t require a cross-county gamble, but far enough removed that we don’t treat your project like a fill-in between two other jobs. We know that older Claremont homes near the Village have specific quirks: shallow floor joists, galvanized supply lines, and vent stacks that never met current code. That local knowledge lets us price accurately before demo day, which is the single biggest reason Claremont homeowners tell us they chose us over a generalist contractor.
Our Bathroom Remodeling Services in Claremont
Full Bathroom Gut Renovations
Full gut renovations are the core of what we do in Claremont, because so many of the bathrooms in this city’s ranch and Craftsman-era homes haven’t been touched since the original build. A gut job means removing everything to the studs and subfloor so we can inspect the framing, replace the supply and drain lines, and rebuild the waterproofing system from scratch. In Claremont, this almost always involves a concurrent electrical upgrade once we see what’s inside the walls. We plan for it from the start so it doesn’t blindside you mid-project.
Shower Pan and Waterproofing Rebuilds
Claremont homes from the 1960s often have mud-bed shower pans that failed years ago. The tile looks fine on the surface, but water has been seeping into the subfloor and the framing underneath. We rebuild these pans with a Schluter waterproofing membrane system, which gives you a code-compliant, leak-free pan that survives our hot inland summers and dry Santa Ana cycles without cracking. This is not a surface patch. It’s a structural fix.
Accessible and Aging-in-Place Bathrooms
Claremont has a lot of homeowners who’ve been in their homes for decades and plan to stay. Curbless showers, reinforced grab-bar blocking, and comfort-height vanities are increasingly common in the mid-century tracts north of Base Line Road. Since we already build ADUs as our core trade, we’re used to designing small, efficient bathrooms that work for aging homeowners and multigenerational arrangements. The same principles translate directly to aging-in-place remodels in the primary residence.
Permit-Triggered Electrical and Structural Upgrades
This is the part of a Claremont bathroom remodel that other contractors gloss over. Once we pull a permit and open a wall on a 1950s ranch, the city inspector is going to require code-compliant wiring, proper venting, and strapped, sisters, or replaced framing where needed. We handle this differently: we write an explicit allowance into your contract for these upgrades before we ever swing a hammer. When we find cloth wiring or a rotted sill plate, we document it, price the fix in writing, and get your signature before we proceed. No surprises, just process.

Trusted Brands We Service in Claremont
We specify James Hardie fiber cement products where exterior work intersects with a bathroom remodel, such as window replacement or wall repairs on second-story bathrooms. Their fiber cement cladding holds up to Claremont’s dry heat and doesn’t warp or rot like wood trim. For prefab elements, our working knowledge of brands like Abodu and Plant Prefab means we understand how modular bathroom pods integrate into ADU projects, which is relevant if you’re pairing a bathroom remodel with a backyard unit on your Claremont lot. We stock common replacement parts and order materials from local Claremont suppliers so we’re not waiting on out-of-state shipments when a rough-in inspection is on the calendar.
Common Bathroom Remodeling Problems We See in Claremont Homes
- Cloth-wrapped wiring behind tile walls. Homes built in the 1950s and earlier in Claremont almost always have cloth-insulated wiring that’s degraded, brittle, and unsafe to reconnect. Opening a wall triggers a mandatory replacement that expands the electrical scope significantly.
- Failed 1960s mud-bed shower pans. The original mortar bed shower systems in Claremont’s mid-century homes were built without a waterproof membrane. They leak into the floor framing for decades and you only find out when the subfloor feels soft.
- Undersized framing around tub surrounds. Older Claremont ranches used 2×4 framing on non-load-bearing walls, which is fine until you open the wall and find the tub surround was never properly blocked. We sister and reinforce framing to meet current code before new cement board goes up.
- Galvanized supply lines with corrosion choke points. The galvanized steel pipes common in 1920s – 60s Claremont homes rust from the inside out. A bathroom remodel is the right time to replace them with copper or PEX, before you close the walls and lose the opportunity for another sixty years.

FAQs – Bathroom Remodeling in Claremont
Because the original wiring was installed with cloth insulation that has degraded over 70 years of hot, dry Claremont summers. When we open the wall and the inspector sees that wiring, code requires us to replace it with modern Romex, run new dedicated circuits for the bathroom, and often upgrade the panel if there isn’t capacity for a new 20-amp branch. That’s not optional, and it’s not something we can finesse. We write an allowance for this exact scenario into every Claremont ranch remodel so it doesn’t become a surprise charge.
Call (877) 801-4497 to have us inspect your bathroom’s wiring before you commit to a remodel. The estimate is free and the inspection tells you exactly what you’re facing.
In most cases, no, because interior bathroom work doesn’t touch protected trees. But if you’re adding square footage, moving a bathroom to an exterior wall, or relocating a window or vent that requires exterior work near a protected oak or camphor tree, Claremont’s Heritage Tree rules can restrict where you dig, place scaffolding, or run new lines. An arborist review becomes a step in the permit process. We’ve worked around rear-yard oaks in Village-adjacent homes enough times to know when this will come up before it derails a schedule.
A pre-demo inspection is exactly what it sounds like: before we swing a hammer, we inspect the accessible framing, look at the visible wiring and plumbing, check the shower pan for signs of past leaking, and run a camera down the drain line if we see any indication of a compromised lateral. This tells us whether your vent stack and sewer lateral are likely to pass rough-in inspection. Skipping this step is how contractors end up tearing out freshly set tile to fix a drain issue that should have been caught before demolition started. We do it first, every time, on every Claremont bathroom older than about 1980.
Because the original vent stacks in Claremont’s 1920s – 60s homes were sized and routed for an era that didn’t anticipate modern plumbing fixtures. Cast-iron vent stacks rust through, galvanized drain lines choke with scale, and clay sewer laterals crack under decades of tree-root pressure from Claremont’s mature street canopy. Once the walls are open, the inspector checks that the venting meets current code. If your existing stack is undersized or corroded, you’re replacing it. We identify this risk during the pre-demo inspection so the cost appears in your initial quote, not as a change order after your bathroom is already torn apart.
We write allowances into the contract before we start. When we find cloth-covered or knob-and-tube wiring, rotted framing, or a failed shower pan, we stop work, document what we found with photos, price the fix in writing, and present it to you for approval. On a 1940s ranch off Indian Hill Boulevard, our crew opened a hall bath and found cloth-insulated wiring fused to knob-and-tube remnants and a rotted sill plate behind the tub surround. We paused work, wrote a change order for a new dedicated 20-amp circuit and sistered framing, and only after the homeowner signed did we reset the cement board and install the Schluter waterproofing membrane. The finished bath passed inspection with no hidden cost added after the fact. That’s the process, every time, on every Claremont project.
