Toto Construction in Highland, CA | Stallion Contractors
We install and repair Toto toilets, WASHLET seats, and shower valves throughout Highland, CA and nearby areas including Toto service in Muscoy as an independent contractor. We’re not a manufacturer-authorized service center, and we won’t pretend to be. What sets our Toto work apart here is that we plan rough-ins and remodels around Highland’s actual conditions: slab movement, hard water, and fire-hazard review requirements on foothill-edge lots. If you need a Toto fixture set, re-set, or rebuilt as part of a bathroom remodel, call (855) 600-3192 for a free estimate.

Why Highland Residents Choose Us for Toto Service
We’ve worked on Toto fixtures across Highland long enough to know exactly how they age in this climate. The mineral-heavy water that runs through a lot of 92346 supply lines scales up Toto fill valves faster than the manufacturer’s design assumptions. The summer dry heat and UV exposure degrade flush-tower seals and seat hinges. And the slab-on-grade construction under a lot of tract homes means seasonal movement that can crack a closet flange. We account for all of it, which is why our Toto repairs and installs here tend to last.
Ruben Montoya, who leads Stallion Contractors, grew up in Colton and trained at San Bernardino Valley College, so the Inland Empire’s soil, water, and building stock aren’t abstractions to us. When a Toto Drake starts rocking on a slab in Highland, we don’t treat it as a mystery. We treat it as a flange problem. That’s the difference between a contractor who knows fixtures and one who knows this ground. Our approach to Toto work is the same as everything else we do: one contractor, every trade, pro-grade materials, professionally installed.

Common Toto Construction Problems We Solve in Highland
- Rocking, weeping toilets from slab movement. Highland’s slab-on-grade tract homes shift seasonally, especially where foothill drainage works under older lots. A Toto that rocks or weeps at the base usually means a crushed wax ring or cracked closet flange. We cut out the old flange, re-set it at the right height, and seat the fixture on a proper reinforced ring. That’s a $200 – $400 repair, not a reason to buy a new toilet.
- Fill valves that chatter or run long. Hard, mineral-heavy water on Highland’s blended and well supply scales the internals of Toto fill valves and flappers. A Drake that runs every few minutes in this area usually needs an OEM fill valve and a good flush of the rim jets. We stock the common Toto OEM parts locally so we’re not waiting on a distributor to get your bathroom working again.
- WASHLET inlet screens and pumps clogging. Sediment and scale in Highland water work their way into WASHLET inlet filters and narrow the spray system over time. On foothill lots, wind-driven dust adds to it. We clean and replace OEM inlet screens and diagnose pump issues before recommending a new seat. Most WASHLET problems on a C100 or C200 are repairable for a fraction of replacement cost.
- UV-brittled flush-tower seals and supply lines. The sun damage on exterior walls and unshaded bathroom windows in Highland’s inland summers is hard on anything rubber or polymer. Toto flush-tower seals crack, supply lines lose resilience, and seat hinges fatigue. When we’re in a shower or bathroom remodel, we swap these out as a matter of course.
- Electronic seat failures in unheated rooms. Highland’s cold snaps aren’t severe, but foothill homes without central heat can drop low enough to stress WASHLET electronics that sit unpowered for weeks. Sensor and control-board failures are more common in these rooms. We diagnose before replacing, because a $40 sensor beats a $400 control board.
Toto Service in Highland: What Local Conditions Mean for Your Equipment
Here’s the piece most Toto pages never touch. Highland’s foothill-edge neighborhoods, especially the parcels that push up toward the wildland-urban interface, fall under San Bernardino County fire-hazard and defensible-space review. A simple bathroom remodel through the flatlands of Redlands Toto service area or San Bernardino pulls an over-the-counter permit. In parts of 92346, that same job can trigger fire-access documentation and WUI requirements before the first wall gets opened. What that means for your Toto rough-in: when a bathroom remodel touches a wet wall or exhaust vent on one of those parcels, the permit our Toto work rides on has to clear the county’s fire review. We bundle the Toto rough-in, the vent relocation, and whatever defensible-space documentation the county asks for into the same permit set. That one detail changes the schedule and sequencing of the job, and it’s exactly the kind of nuance a contractor from the flatlands won’t see coming until the plan check kicks it back. Good work doesn’t need a sales pitch, it needs the right materials and someone who knows what they’re doing.
On a 1970s stucco-and-tile tract home up in the foothill edge of 92346, our crew opened a hall bath and found the original Toto Drake rocking on a slab that had moved just enough to crush the wax ring and crack the closet flange. We cut out and re-set the flange, corrected the drain slope, added a reinforced wax ring, and re-set the Toto with a fresh OEM fill valve. Then we re-poured the patch so the toilet seated flat before the new tile went down.
Toto Models & Products We Service in Highland
We work on the full range of Toto fixtures homeowners in Highland actually have: Drake and Eco Drake two-piece toilets in both 1.28 GPF and dual-flush versions, UltraMax and Ultramax II one-piece comfort-height models, WASHLET electronic bidet seats from the C100, C200, and S series, and occasionally Neorest integrated smart toilets. Our repair philosophy is straightforward: use genuine Toto OEM fill valves, flappers, wax rings, and WASHLET inlet filters. We’ll turn to quality aftermarket parts only when a model is discontinued or a homeowner on an older Drake wants the lower-cost repair. We’ll also tell you without hedging when a 15-year-old toilet needs a $30 valve versus a new bowl. For broader Toto sales & service across our territories, including Toto specialists coverage, we carry the same parts discipline everywhere we run.

FAQs – Toto Construction in Highland
Not for a simple fixture swap. You need it when the job touches what the county classifies as construction in a high fire hazard zone, like moving a wet wall, relocating an exterior vent, or adding square footage on a foothill-edge parcel. A straight toilet replacement under the same permit as a larger remodel may ride on a plan check that includes fire review, but the toilet itself is not the trigger. Call (855) 600-3192 and we’ll tell you what your specific parcel needs.
In most Highland homes, a running or chattering Drake is a fill valve struggling with mineral deposits from hard water. The dry heat accelerates water evaporation in the tank, which cycles the fill valve more often and lets scale build up inside it. We replace with an OEM Toto fill valve and flush the rim jets. If it’s a deeper supply-line or flange issue, we’ll tell you before we touch anything. Call (855) 600-3192 for a diagnosis.
Usually, yes. A Toto WASHLET needs a GFCI outlet near the toilet, and on older Highland tract homes that’s often missing. We run a dedicated GFCI line during a remodel or as a standalone service. The bigger long-term issue in this area is sediment in the water, so we install an OEM inlet filter and show you how to clean it seasonally. For an exact fit and install quote on your bathroom, call (855) 600-3192.
Yes, that’s one of the most common calls we get in Highland. Rocking almost always goes back to the slab and the flange under the toilet. We cut out the old flange if it’s cracked, re-set it at the correct height, and seat the Toto on a reinforced wax ring. The repair usually takes half a day. Call (855) 600-3192 if you notice movement or moisture at the base. Waiting makes the slab contact worse.
We do. Toto shower valves and trim go into our walk-in shower and tub-to-shower conversions in Highland and Toto repair in Loma Linda, and we coordinate the rough-in with any county fire or defensible-space review that applies to the parcel. The valve gets set to Toto’s specified depth, which matters more than homeowners expect. For a detailed walk-in shower or bathroom remodel quote in Highland, call (855) 600-3192. Estimates are free.
