Toto Construction in Montclair, CA | Elmwood Contractors
We provide independent Toto construction service across Montclair, CA, from rough-in through final trim on bathrooms that were mostly built between the late 1940s and the 1960s. The thing that makes our Toto work here different is simple: we spec the fixture around Montclair’s undersized original electrical service and shallow lot setbacks, not the other way around. When a Toto Washlet or Neorest goes into a Montclair tract home, the panel upgrade and permit path usually matter more than the fixture itself. Call (866) 253-8554 for a free estimate, and know that we’re an independent contractor, not a Toto-authorized partner. For a full look at our Toto sales & service, that page covers the lineup.
Why Montclair Residents Choose Us for Toto Service
Most of the homes we work in across Montclair service area are single-story stucco tract houses with original slab-on-grade bath floors. That means a Toto Drake’s rough-in dimensions, a Toto Aquia’s water pressure needs, and a Washlet’s dedicated-circuit requirement all get checked against what the house actually has, not what the spec sheet assumes. We pull the fixture data sheet before we cut anything. Nolan Shepherd, our owner, grew up in Fullerton’s Sunny Hills neighborhood, where he learned early which 1960s houses were going to have foundation issues, and he’s spent two decades running Elmwood Contractors on the principle that the right material in the right place is the whole job. Everything else is just catching up to that decision. We use genuine Toto OEM fill valves, flush towers, tank gaskets, and Washlet control boards when the part affects flush performance or electronics, and quality aftermarket only where it’s a commodity: supply lines, wax rings, closet bolts, flanges. We carry the common Toto parts for Montclair-area jobs locally so we’re not waiting on a distributor in Riverside or LA.

Common Toto Construction Problems We Solve in Montclair
- Weeping wax rings and rocking Toto Drakes. Montclair’s original slab-on-grade tract bath floors have closet flanges that were set decades ago and have dropped slightly out of plane relative to finished tile. On mid-century single-story stucco homes, that quarter-inch drop is the classic setup for a slow wax-ring leak that shows up weeks after a remodel. We reset the flange at the right height and reseat the fixture with OEM gaskets.
- Fill valves and inlet screens scaled with Inland Empire hard water. The water here in the San Gabriel Valley / Inland Empire transition is mineral-heavy, so Toto 1.28 gpf fill valves slow-fill and run long before the flush tower ever fails. Homeowners call us thinking the toilet is dying. It’s usually a $35 OEM fill valve and a cleaned inlet screen, not a new unit.
- Washlet electronics tripping GFCI on original 1950s-60s branch wiring. Older Montclair baths never had a dedicated circuit for a heated Toto Washlet seat. The seat’s control board sees voltage sag or a tripping shared circuit, and the electronics glitch. We handle the panel and circuit work as part of the installation, and we pull the permit.
- Tank-to-bowl gasket loosening and tank sweating during hot dry summers. Seasonal thermal cycling in unconditioned Montclair garages and baths loosens tank hardware on Ultramax and Drake two-piece units. Bolts corrode, gaskets stretch, and you get a small slow drip where the tank meets the bowl. Tightening alone doesn’t fix it long-term; replacement OEM gaskets and properly torqued bolts do.
- Flush tower and float problems after a Montclair remodel changes water conditions. When a bathroom remodel adds a new pressure-balancing valve or changes supply line routing, the Toto’s flush tower can see erratic pressure. We catch it during rough-in and adjust the valve or the supply layout so the fixture performs like the spec says.
Toto Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair is a small, largely built-out Inland Empire city where most construction is infill and renovation on aging postwar tract housing rather than new development. That means the Toto work we do here rarely starts with a blank slate. On Montclair’s older single-story tracts, additions and second-story projects frequently run into undersized original electrical service and shallow lot setbacks, so plans often require panel upgrades and careful lot-coverage review before permits clear. For homeowners needing Toto service in Ontario and nearby, this shows up in a very specific way: a bathroom remodel that adds a Toto Washlet or moves a shower valve frequently requires a panel upgrade and lot-coverage review before the permit clears. The panel, not the fixture, is often the long pole. We’ve worked on homes off Holt Boulevard where the original 60-amp panel from the 1950s simply can’t carry a heated seat, a new bathroom circuit, and the rest of the house at once. We plan for that from day one, so the Toto install doesn’t stall at the permitting counter.
On a late-1950s single-story stucco tract home off the Holt Boulevard corridor, our crew pulled a tired builder-grade toilet and found the original closet flange sitting roughly a quarter-inch below the new tile we’d laid, the classic setup for a weeping wax ring. We reset a Toto Drake on an offset flange to correct the height, replaced the fill valve and tank gasket with OEM Toto parts, and added a dedicated GFCI circuit so the homeowner’s Washlet seat could go in without overloading the original branch wiring. That job took one coordinated visit because we had the parts and the permit path worked out before we opened the wall.
Toto Models & Products We Service in Montclair
We service the Toto lines most common in Montclair homes: the Drake CST744 series gravity two-piece, the Ultramax II one-piece, the Aquia dual-flush, and the Washlet and Neorest electronic bidet seats and integrated units. Most Montclair tract baths have a Drake or a builder-grade equivalent that was put in during a previous remodel, and a fifteen-year-old Drake is usually a valve, gasket, and flange job, not a replacement. We use genuine Toto OEM fill valves, flush towers, tank gaskets, and Washlet control boards for anything that affects flush performance or electronics. For commodity parts like supply lines, wax rings, closet bolts, and flanges, quality aftermarket gets it done. We only recommend a new fixture when the porcelain bowl is cracked or the rough-in itself has to move.

FAQs – Toto Construction in Montclair
Yes. Most original Montclair tract homes from the 1950s and 60s have branch wiring that was never sized for a heated bidet seat. A Toto Washlet needs a dedicated GFCI circuit, and if your panel can’t support it, the permit won’t clear until the panel is upgraded. We handle that as part of the job. Call (866) 253-8554 and we’ll tell you exactly what your panel can carry.
The original closet flange on a slab-on-grade Montclair tract bath has usually dropped slightly out of plane relative to the new tile. That gap causes the wax ring to weep and the fixture to rock. We reset the flange at the correct height and reseat the unit with OEM gaskets. It’s a common problem here, and it’s fixable in one visit.
Almost never. In Montclair’s hard water, the Toto 1.28 gpf fill valve’s inlet screen gets mineral-scaled and the valve slows down. The flush tower usually still works fine. We replace the OEM fill valve and clean the screen, and the tank refills like new. Call (866) 253-8554 for a diagnosis; most of these are under a hundred dollars in parts.
Yes, and that’s a big part of our work here. A tub-to-shower conversion in a Montclair single-story means moving the drain, replumbing the valve, and often upgrading the circuit if you’re adding a Washlet or heated floor. The shallow lot setback doesn’t affect the interior work, but the panel often does. We pull the permit and coordinate the entire job.
Mostly the Drake CST744 series two-piece, with some Ultramax II one-piece units in homes that were remodeled in the last 15 years, plus a growing number of Washlet seats retrofitted onto existing Drakes. The Aquia dual-flush shows up less often, and Neorest integrated units are rare but we do service them. If you’re not sure what you have, call (866) 253-8554 and we’ll identify it from a photo.
