Toto Construction in Highgrove, CA | Stallion Contractors
We provide independent Toto fixture installation, service, and repair across Highgrove, CA, and we’re known locally for handling the county-permitting complications that come with unincorporated Riverside County work. Most Toto jobs here run through Riverside County Building & Safety, not a city desk, and on well-and-septic lots that means an extra environmental health sign-off before we can close up a wet wall. If you’re planning a Toto swap or a full bath remodel in Highgrove, call (855) 600-3192 for a straight answer and a free estimate.

Why Highgrove Residents Choose Us for Toto Service
We have installed and serviced Toto repair in Loma Linda and across the Inland Empire long enough to know the brand’s supply-chain quirks, its proprietary flush-tower geometry, and when an OEM rebuild genuinely beats a swap, and we do it all without any claim to be affiliated with Toto. Stallion Contractors is an independent Toto service provider, full stop.
Ruben Montoya, our owner, grew up in Colton not far from Pepper Avenue, where half the houses on his block were built by tradesmen who knew the Inland Empire soil and sun better than anyone. He picked up his foundation in construction at San Bernardino Valley College, where the hands-on programs put him on job sites before he ever had a business card. That background matters in Highgrove, where the housing stock is older mid-century construction on large rural lots, and a Toto install often means working around slabs poured in the 1950s, private wells, and septic laterals that were never mapped on a clean set of drawings.
We stock genuine Toto OEM fill valves, flush towers, and gaskets for the Drake and Ultramax families, so when a Highgrove customer calls with a running toilet or a weak flush, we’re not ordering parts and waiting a week. We also carry the trade-grade surrounding materials that let us handle a Toto install as part of a fuller bath renovation: Toto sales & service is one piece of what we do, but we approach every fixture swap with an eye to the whole wet wall.
Styles & brands we work with







Common Toto Construction Problems We Solve in Highgrove
- Hard-water scale from private wells. Highgrove has a lot of properties on private wells rather than treated municipal water, and that mineral load cakes Toto rim jets and canister flush valves fast. On Drake and Ultramax units we regularly see flush performance degrade in a year or two, not the five or six you’d expect on city water. We descale jets, rebuild towers, and set realistic expectations about maintenance on well-supplied Toto fixtures.
- Gasket and wax-ring failure on aging mid-century slabs. Many Highgrove homes are 1950s and 1960s builds, and the original closet flanges are often rusted, cracked, or sitting proud of the slab. Re-setting a Toto over an original flange gets tight on rough-in dimensions, and when we pull the bowl we sometimes find the flange itself needs rebuilding before any new fixture goes down.
- Flush-tower and fill-valve wear on Toto G-Max engines. This shows up as phantom running or a weak flush that owners misdiagnose as a clog. The G-Max tower seal wears, the fill valve drifts, and the toilet runs intermittently. We stock the OEM rebuild parts, so this is usually a same-visit fix rather than a replace-the-toilet situation.
- Washlet electronic seats failing in hot, dusty Inland Empire wiring runs. Toto Washlet seats fail most often at the power supply or the wand motor, and in Highgrove’s heat and dust, exposed runs through attics and garages take a beating. We diagnose the seat before recommending a motherboard swap or a new unit, because the failure is rarely the bowl.
- Cracked one-piece bowls from shifting slabs. Ultramax and other one-piece Toto models sit heavy on a slab, and when a Highgrove slab shifts with seasonal soil movement, a hairline crack at the base can leak slowly into the floor. We’ll tell you honestly when a cracked one-piece bowl means replacement with a new Toto rather than a patch that won’t hold.
Toto Service in Highgrove: What Local Conditions Mean for Your Equipment
Because Highgrove is unincorporated, every Toto fixture swap or bath remodel here runs through Riverside County Building & Safety rather than a city permit desk. That’s not a formality. On well-and-septic lots, which are common throughout the 92313 ZIP, the county also requires separate environmental health sign-off before a wet-wall Toto install can be closed up and inspected. What that means in practice: we sequence rough-in so the county can see the supply and drain work, we coordinate the environmental health review on the septic side, and we don’t let a homeowner pour tile or set a vanity until the paperwork is clear. A contractor who works mostly in incorporated Riverside or San Bernardino won’t think about that sequencing, and the job stalls at inspection. We’ve done enough Highgrove work now that the county process is just part of how we schedule. Good work doesn’t need a sales pitch, it needs the right materials and someone who knows what they’re doing.
Toto Models & Products We Service in Highgrove
We service the Toto Drake and Drake II two-piece elongated toilets, the Ultramax II one-piece line, EcoPower and EcoPromenade high-efficiency models with 1.28 gpf flush engines, and the full Washlet electronic bidet seat range. The distinction we bring to this work is parts discipline: genuine Toto OEM fill valves, flush towers, and gaskets for the Drake and Ultramax families, with quality aftermarket only where Toto doesn’t manufacture the wear part. That means a rebuild holds its flush for years, not months. For Highgrove turnaround, we keep common Drake and Ultramax rebuild parts on hand, so the call that starts as “my Toto keeps running” usually ends the same day.

A Toto fixture swap on its own usually falls inside the broader bath scope rather than as a standalone ticket, because most Highgrove homes need at least some flange work, valve replacement, or drywall repair around the fixture. Our free estimate walks the wall with you and gives you a written number before any work starts. Call (855) 600-3192 to schedule one.

FAQs – Toto Construction in Highgrove
Yes, and we do it regularly. The real issue on private well supply is mineral scale, so we recommend descaling the rim jets periodically and keeping a close eye on the G-Max fill valve, which tends to wear faster on untreated water. Call (855) 600-3192 if you want a well-specific assessment before you buy a fixture.
In most cases, a direct fixture-for-fixture swap on an existing rough-in does not require a county permit, but any change to the drain location, water supply routing, or wall assembly will. Because Highgrove is unincorporated, Riverside County Building & Safety is the authority, and on septic lots the environmental health side has to sign off if we touch drainage. We handle that determination on the estimate call so there are no surprises at inspection.
That’s almost always a worn G-Max flush tower seal or a drifting fill valve, and both are stock OEM rebuild parts for the Drake and Ultramax families. It is not a clog. On Highgrove well water, the mineral buildup accelerates the seal wear. Call (855) 600-3192 and we’ll tell you over the phone whether it sounds like a tower seal, and if it is, we can usually fix it in one visit.
Yes, and the best time to do it is during rough-in, when we can run a dedicated GFCI circuit to the seat location instead of tapping an existing bathroom outlet. Highgrove attics and garages get hot and dusty, so the power run itself matters more than the seat. We coordinate the electrical with the same crew doing the wet wall, so you’re not juggling a second contractor.
It adds at least one county environmental health inspection before we can close the wall, and on older septic systems it sometimes triggers a required repair or upgrade first. On a Highgrove lot with a 1960s leach line, that’s the part of the job that moves the schedule. Call (855) 600-3192 and we’ll pull your property details and give you a realistic sequence before you commit.
