Toto Construction in Rancho Cucamonga, CA | Sawyer Remodeling
We’re Sawyer Remodeling, an independent Rancho Cucamonga General Contractor that installs and services Toto toilets, Washlets, and shower systems. We’re not authorized by Toto and we don’t pretend to be. What we are is local: we know the hard-water problems Rancho Cucamonga’s Colorado River supply throws at Toto fixtures, and we stock the OEM parts that actually fix them. Need Toto work done right?

Why Rancho Cucamonga Residents Choose Us for Toto Service
Most plumbers can swap a toilet. Fewer can tell you why your Toto Drake II phantom-flushes at 3 a.m. or why your Washlet’s wand stopped spraying like it should. We see those calls weekly across Rancho Cucamonga. Luca Romano, our owner, came up the old way: framing and finish carpentry at LA Trade-Tech, then two decades of remodel work where clean tile and plumbing that actually holds up matter more than anything else. Good work doesn’t need a sales pitch – it just needs to be done right. That’s the standard we bring to every Toto job, whether it’s a full Bathroom Remodeling in Rancho Cucamonga project in a Terra Vista home or a fixture swap in a 1990s tract house off Carnelian.
We carry genuine Toto OEM flush valves, fill valves, wax rings, and Unifit adapters on the truck because we know Rancho Cucamonga’s mineral-heavy water kills cheap aftermarket parts fast. Our techs are background-checked and show up in uniform. You get a written price before any tool comes out, and the 365-Day Done Right Promise backs every repair. If a fix fails, we come back free. No argument, no invoice.

Common Toto Construction Problems We Solve in Rancho Cucamonga
- Scaled rim holes and jets on Drake and Ultramax bowls. Rancho Cucamonga’s Colorado River water carries enough dissolved minerals that Toto’s rim jets clog within a few years on many homes. The result is a weak, uneven flush that leaves waste behind. We clear the scale and replace the flush components when they’re too far gone.
- Washlet wands and heater elements caked with calcium. Our hard water attacks the Washlet’s wand outlets and the internal heating element faster than Toto ever designed for. Weak spray, no warm water, or a blinking error light are the usual signs. We descale first, replace OEM parts when the buildup has gone too far.
- Constant running and phantom flushes from worn 3-inch flappers. The newer Drake II series uses a 3-inch flapper that hard-water scale loves to chew up. The toilet runs, then flushes on its own in the middle of the night. We replace the flapper and fill valve with genuine Toto parts, not the generic ones that never quite seal.
- Failing Unifit adapter seals and wax rings on slab foundations. Most Rancho Cucamonga tract homes sit on concrete slabs, not raised floors. When a wax ring or the Toto Unifit seal degrades, sewer gas creeps into the bathroom and the toilet can rock or drain slowly. We reset the toilet properly so the flange and seal line up.
- Builder-grade Toto bowls from the 1980s and 1990s reaching end of life. These original fixtures predate low-flow rules, so they flush with more water than today’s models. Parts are still available, which surprises most homeowners. We help you decide when to repair versus when it’s smarter to swap in a modern Toto during a remodel.
Toto Service in Rancho Cucamonga: What Local Conditions Mean for Your Equipment
Here’s something specific to Rancho Cucamonga that you won’t hear about in most other cities: a huge share of the homes here were built between the 1980s and early 2000s, and many of those homes got Toto toilets as original builder-grade fixtures. That means we’re regularly working on Toto bowls that are 20 to 30 years old, long past their expected life, but still repairable because Toto parts stay available for decades. In Toto in Ontario and other older housing markets nearby, you’d find more mixed-brand plumbing. Here in neighborhoods like Alta Loma, Terra Vista, and Etiwanda, Toto was a go-to spec builder choice, so the failure patterns are consistent and predictable. We’ve seen the same hard-water scaling, the same flapper wear, and the same slab-floor seal issues over and over, which means we diagnose faster and fix it right the first time. When you’re planning a remodel in a Rancho Cucamonga home from that era, factor the original plumbing into the plan instead of getting surprised mid-project.
Toto Models & Products We Service in Rancho Cucamonga
We work on the full range of Toto fixtures common in this area: Toto sales & service covers the Drake and Drake II two-piece toilets (CST744 series), the Ultramax and Ultramax II one-piece (MS854 series), the Vespin, Aquia, and EcoPromenade lines, plus Washlet electronic bidet seats including the S500e and S550e. We also handle Toto shower valves and trim during rough-in work. Our parts approach is simple: OEM first. Aftermarket flush valves and fill valves rarely match Toto’s geometry, and a toilet that doesn’t seal right is a callback waiting to happen. We keep the common OEM parts stocked locally so Rancho Cucamonga jobs don’t stall waiting on a shipment.

FAQs – Toto Construction in Rancho Cucamonga
Why does my Toto Washlet stop heating water after a year or two in Rancho Cucamonga? The heating element inside the Washlet gets coated with calcium from our hard Colorado River water, which blocks heat transfer and makes the unit run cold. We descale the element and wand, and if the buildup has already damaged the element, we replace it with the OEM Toto part. Call (254) 272-5876 if your Washlet is running cold and we’ll diagnose it.
Can you fix a Toto toilet that runs constantly even after I replaced the flapper myself? Yes, and we see it all the time in Rancho Cucamonga. Usually the aftermarket flapper doesn’t seat correctly on Toto’s flush valve, or the fill valve is scaled and letting water creep over the overflow. We install genuine Toto OEM flappers and fill valves so the toilet seals the way Toto designed it to.
Do you install Toto Washlets on existing non-Toto toilets during a bathroom remodel? We do. A Washlet can work on many standard toilet models, but the rough-in and electrical requirements need to be checked first. During a Small Bathroom Remodel we plan for the outlet placement and water supply so the seat installs cleanly without visible cords or awkward plumbing, whether you’re in Rancho Cucamonga or need Toto service in Fontana. Call (254) 272-5876 and we’ll tell you what your bathroom needs.
My Toto toilet is from the 1990s – is it worth repairing or should I replace it during a remodel? If it’s a 1990s Toto and the bowl is sound, repair is usually worth it because parts are still available and the older models flush with more water than today’s low-flow units. If the bowl is cracked, the finish is shot, or the electronics on a Washlet are obsolete, we’ll recommend replacing with a like-for-like modern Toto. The decision depends on what we find when we pull the toilet. Estimates are free: (254) 272-5876.
Can you replace just the Toto shower valve or trim without tearing out the whole shower? Usually yes. We can replace the Toto shower valve cartridge and trim through the existing opening in many cases, saving the tile and surrounding wall. If the valve body itself is bad or the rough-in isn’t accessible, we’ll walk you through a minimally invasive repair path using the Walk-In Shower Installation crew. Call (254) 272-5876 for a hands-on look.
