Toto Construction in Los Altos Hills, CA | Viceroy Construction
Viceroy Construction provides independent Toto installation, Toto repair in Los Altos, and full bathroom remodeling across Los Altos Hills, CA. We’re not a Toto dealer or authorized warranty center. What we are is a general contractor that has pulled Toto fixtures out of 1970s hillside homes, replaced them with current high-efficiency models, and dealt with the permit and well-water realities that make Los Altos Hills different from every flatland city around it. If your Toto toilet is acting up or you’re planning a bathroom remodel, call (877) 358-6557 for a free estimate.
Our Toto sales & service work spans the entire Los Altos Hills service area, from original Drake toilets in 1960s ranches to Aquia dual-flush units in recently built contemporary estates.
Why Los Altos Hills Residents Choose Us for Toto Service
We know Toto products the way a carpenter knows lumber. We’ve installed and serviced Drake, Eco Ultramax, Aquia, and Washlet fixtures across hundreds of Los Altos Hills bathrooms and kitchens. Our crew can identify a degraded fill valve diaphragm by sound and a sticking flush tower by feel. That product-specific experience matters when your toilet has been running for six months and your well pump is cycling twice an hour.
Neil Drummond, who leads Viceroy Construction, grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where framing, concrete, and structural coursework built the foundation he still uses when scoping a job. The details you don’t see are the ones that matter most. That’s why we use OEM Toto fill valves, flush towers, and seat assemblies rather than generic aftermarket parts that misalign in Toto’s low-profile tanks. An aftermarket valve might save $15 on the part and cost you $400 in water waste over the next year.

Common Toto Construction Problems We Solve in Los Altos Hills
- Drake fill valves that never stop running. Toto Drake fill valve diaphragms degrade faster under Los Altos Hills’ hard well water. The symptom is constant refilling between flushes. We replace the valve with an OEM Toto unit, which restores the fill cycle and stops the phantom flow. Homeowners usually notice the well pump quieting down within a day.
- Eco Ultramax flush towers that stick after winter storms. When hillside septic systems back up during heavy winter downpours, the Eco Ultramax flush tower takes on sediment and debris. The seal degrades, the tower sticks, and you get phantom flushes. We swap in a new OEM tower and inspect the tank for mineral buildup.
- Aquia dual-flush cartridges seizing from mineral-rich well supply. The Aquia’s dual-flush cartridge is the first thing to corrode when your well water carries high mineral content. A seized cartridge causes weak flushes or a full-flush button that does nothing. We replace the cartridge with the OEM part and check the supply line for scale.
- Washlet seats failing at the power supply or wand motor. Older 1950s – 1980s Los Altos Hills homes often have original wiring with voltage fluctuations. That stress lands on the Washlet’s electronic components. We diagnose whether the fault is the seat assembly or the electrical supply, then repair or replace accordingly.
- Leaks from failed connections that stain ceilings below. A slow leak at a Toto supply line or tank gasket in an upstairs bathroom often goes unnoticed until it shows up as a brown stain on the ceiling below. We trace the leak, replace the failed component, and repair or patch the affected drywall.
Toto Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Here’s something most contractors from flatland cities don’t understand until they fail an inspection: Los Altos Hills properties rely on private wells and septic systems, not municipal water and sewer. Any new construction or addition, including a bathroom remodel that adds a Toto toilet or shower, requires a perc test and well-flow verification before the town will issue a permit. That step routinely adds weeks to projects and changes how we stage the plumbing rough-in. We’ve learned to schedule the perc test first, design the fixture layout around the verified water flow, and order Toto fixtures early so the permit wait doesn’t stall progress. On a recent Mountain View Toto service call for a master bathroom remodel in a 1970s home off Elena Road, the original Toto Eco Ultramax had been running nonstop due to a mineral-clogged fill valve and failing flush tower. After we swapped in OEM parts and rebuilt the shower with a Toto wall-hung toilet and frameless glass enclosure, the homeowner noticed the well pump cycling less almost immediately. The job also uncovered a non-permitted deck addition, which we flagged and helped the owner legalize before final inspection.
Toto Models & Products We Service in Los Altos Hills
We service the full Toto line you’re likely to find in Los Altos Hills homes: the Drake, the Eco Ultramax, the Aquia dual-flush, and the Washlet electronic seat. Our parts approach is simple. For anything inside the tank, the flush mechanism, or the seat assembly, we use OEM Toto parts. Aftermarket valves frequently misalign in Toto’s low-profile tanks and cause recurring leaks that cost more in water and callbacks than the OEM part ever would. For older toilets, we’ll always give you an honest repair-vs-replace comparison. Once a Toto’s ceramic trapway or flush tower is cracked, a new high-efficiency model often costs less than chasing parts. We keep common Toto components in stock for fast Los Altos Hills turnaround: fill valves, flush towers, dual-flush cartridges, tank gaskets, and seat assemblies.

FAQs – Toto Construction in Los Altos Hills
The most common cause in Los Altos Hills is a degraded fill valve diaphragm, which wears out faster under hard well water with high mineral content. When the diaphragm fails, water trickles into the tank continuously and the valve never fully shuts. We replace the fill valve with an OEM Toto unit, test the tank for scale, and the refilling stops. Call (877) 358-6557 for an exact diagnosis, and estimates are free.
Yes, in Los Altos Hills you will likely need a perc test and well-flow verification before the town issues a permit for any bathroom remodel that adds or relocates a Toto fixture. This is a non-negotiable part of building on private well and septic systems. We schedule the test first, design the rough-in around the verified flow rate, and factor the timeline into your schedule so the permit wait doesn’t stall the project.
Yes. We handle tub-to-shower conversions and walk-in shower remodels as a core part of our bathroom work. The job typically runs $4,500 to $12,000 for the shower itself, depending on tile, glass enclosure, and whether we need to move the Toto drain line or update the vent stack. We’ll give you a written quote before we touch a single tile.
It depends on the failure point. If the issue is the seat’s heating element or control board, a repair can make sense on a newer Washlet unit. If the seat is over five years old and the wand motor has also failed, a replacement seat often costs less than chasing parts and labor. We diagnose the fault first, then give you a repair-versus-replace price. Call (877) 358-6557 and we’ll tell you straight.
In Los Altos Hills, the usual culprit is a corroded dual-flush cartridge. Mineral-rich private well water deposits scale on the cartridge, which then seizes and prevents the full-flush mechanism from engaging. We replace the cartridge with an OEM Toto part and flush the supply line to remove loose scale. The job is typically completed in one service visit.
