Toto Construction in Fontana, CA | Polaris Contractors
We provide Rialto Toto service and independent Toto service across Fontana, from the 1950s tract homes south of the 10 to the newer master-planned subdivisions up north. What sets our Toto work apart here is simple: we know how Inland Empire hard water and Santa Ana heat actually wear down fill valves, flanges, and Washlet electronics. Rick Sondermann leads our team, and we’ve spent the better part of three decades fixing what other contractors miss. Call (855) 473-6535 for a free estimate.
Why Fontana Residents Choose Us for Toto Service
Toto makes a genuinely good toilet. The Drake’s gravity-flush design and the Ultramax II’s one-piece construction hold up well in most homes. But Fontana water is hard, mineral-heavy, and unforgiving to rubber seals and solenoid valves. We work on Toto fixtures every week across 92335, 92337, and the surrounding ZIP codes, so we already know which parts fail first and which ones don’t fail at all. Rick learned construction fundamentals at Saddleback College and has spent decades remodeling homes up and down Southern California. That background means we treat a toilet replacement as part of the larger bathroom system, not an isolated swap. We’re an independent Toto service provider offering Glen Avon Toto service, not manufacturer-authorized, and we say so plainly because you deserve to know who’s actually doing the work.

Common Toto Construction Problems We Solve in Fontana
- Ghost flushing and running tanks on Drake and Ultramax II units. Fontana’s hard water leaves scale on the fill valve seal. The result: your toilet refills itself a few minutes after every flush. We replace the OEM fill valve and flush the supply line, which fixes it permanently.
- Wax ring and flange failures in older 92335 homes. The post-war tract houses south of the 10 often have cast-iron closet flanges that crack after 60-plus years. The toilet rocks, sewer gas seeps in, and moisture reaches the subfloor. We pull the bowl, assess the flange, and re-set everything level.
- Washlet electronic faults after hot summers. Fontana sees 100°F-plus heat and Santa Ana dust. That combination stresses inlet solenoids and control boards on S-series and C-series Washlets. Units lose water flow or throw error codes. We replace the solenoid or board with Toto OEM parts when repair makes sense.
- Tank-to-bowl gasket and bolt corrosion on Aquia and Drake two-piece units. Original galvanized supply lines in older Fontana homes deliver low pressure and sediment. The gaskets degrade faster than they should. We replace them and often recommend upgrading the supply line while we’re there.
- Rocking toilets that never sit right. This is common near the former Kaiser Steel footprint, where slab settlement and buried mill-era fill make flanges uneven. We re-bed the flange, not just drop a new wax ring, so the toilet stops moving.
Toto Service in Fontana: What Local Conditions Mean for Your Equipment
On the older south-side blocks near the former Kaiser Steel footprint, excavating for a bathroom addition or slab move routinely turns up buried mill-era debris and undocumented fill. That discovery changes how we rough in new DWV lines and set a Toto toilet flange. The soil under the slab isn’t native or evenly compacted like it is in the north Fontana tracts. If you’re adding a bathroom in 92335 and we’re setting a Toto Drake or Aquia, we provide Pedley Toto service that accounts for that fill before the concrete ever gets poured. A flange set on unstable fill will crack within a few years, and then your toilet rocks and leaks. This is a Fontana-specific problem you won’t read about on a generic Toto page. We plan for it from the first cut.
Toto Models & Products We Service in Fontana
We service the Toto lines Fontana homeowners actually own: the Ultramax II one-piece high-efficiency toilet, the Drake two-piece gravity-flush family (CST743/CST776), the Aquia dual-flush, and the Washlet electronic bidet seats in S-series and C-series. Our parts approach is straightforward: we default to genuine Toto OEM fill valves, flanges, and Washlet solenoids because flush geometry and electronics depend on them. For wax rings, supply lines, and bolts, we use quality aftermarket parts where OEM adds cost without any real benefit. We stock common Toto components locally so Fontana turnaround stays fast. If a bowl or tank is cracked, or a Washlet board is priced near a new seat, we’ll tell you replacement is the smarter spend. That’s part of Toto sales & service done honestly.

FAQs – Toto Construction in Fontana
My Toto Drake keeps refilling itself a few minutes after every flush – is that a Fontana water problem?
Yes, and it’s the most common Toto issue we see in Fontana. The city’s hard, mineral-heavy water builds scale on the fill valve seal. We replace the OEM fill valve and flush the supply line. Call (855) 473-6535 for an exact quote. Estimates are free.
A bathroom addition in south Fontana hit buried debris from the old Kaiser mill site – does that affect installing a new Toto toilet?
It absolutely does. Mill-era fill isn’t evenly compacted, so flanges set on it crack over time. During your addition we re-bed and re-level the flange before the Toto goes in. Not every General Contractor – Fontana accounts for this. We do. Call (855) 473-6535 to discuss your project.
Is my Toto Washlet repairable when it stops spraying, or do I need a new one?
Usually repairable. The inlet solenoid and control board are the parts that fail in Fontana’s heat and dust, and both are replaceable with Toto OEM components. If the board cost approaches a new seat, we’ll tell you that plainly.
Can you replace a Toto toilet during a tub-to-shower conversion in a 1990s north Fontana home?
Yes. North Fontana’s 1990s and 2000s tracts are easier to work in than the older south-side homes because slab conditions are more predictable. We coordinate the toilet swap with the shower conversion so you’re not paying for two separate visits. Call (855) 473-6535 for a free estimate.
Do you use genuine Toto parts, and are you authorized by Toto?
We use genuine Toto OEM parts for fill valves, flanges, and Washlet electronics. We are not authorized, sponsored, or endorsed by Toto. We’re an independent contractor serving Fontana service area and the surrounding communities.
