Toto Construction in Sunnyvale, CA | Ashford Contractors
Ashford Contractors provides independent Toto construction and installation service across Sunnyvale, from full bathroom remodels to precise fixture setting and Washlet wiring. We’re not authorized by Toto, and we’ll tell you that straight. What we bring is something rarer in Sunnyvale’s ranch-dominated housing stock: hands-on experience with Toto fixtures on slab-on-grade 1950s and 60s homes, where cracked bases, failed flanges, and scaled Washlet valves show up more than anywhere else in the Bay Area. Call (877) 752-3868 for a free estimate, and we’ll price the work correctly the first time.
Why Sunnyvale Residents Choose Us for Toto Service
Our crews have installed and repaired Toto Drake, Eco Ultramax, Aquia, and Washlet systems in hundreds of Bay Area bathrooms, and a good share of those were right here in Toto in Santa Clara County’s older neighborhoods. Glen Mossier, our owner, grew up in Foster City watching lagoon-side homes get rebuilt after water damage, and he trained in construction technology at Skyline College in San Bruno. That background shows up in how we approach a Toto job in Sunnyvale: we check the slab before we set the bowl, we verify the shut-off before we touch the supply line, and we don’t pretend a cracked flange is a wax-ring problem. We use OEM Toto fill valves, flappers, gaskets, and Washlet seat assemblies on core components because aftermarket clones cause recurring leaks and sensor faults. For supply lines and shut-offs, we specify Fluidmaster or brass quarter-turn stops that meet or exceed OEM spec. Build it right the first time, and you won’t be rebuilding it in ten years.

Common Toto Construction Problems We Solve in Sunnyvale
- Cracked Toto bases on settled slabs. In the 94086 and 94087 ranch tracts, original slab-on-grade floors shift over decades. A porcelain Toto bowl mounted on an aging closet flange can crack at the base from that movement, and the first sign is usually a faint sewer smell or a toilet that rocks under weight. We open the floor, replace the flange, level the patch, and reset the fixture so it doesn’t crack again.
- Weak Washlet spray and sensor faults in unvented bathrooms. Post-war Sunnyvale ranches often have small, poorly vented or recirculated-air bathrooms. Mineral scale from Sunnyvale municipal water builds up faster in those conditions, clogging Washlet nozzles, sensors, and valves. We descale and replace worn Washlet seat assemblies, and we’ll tell you if the real fix is adding proper bath ventilation.
- Phantom flushing and running Toto toilets in high-cycle households. Original 1.6 GPF conversions on older supply lines often skipped checking supply pressure and shut-off condition. Toto fill valves and flappers in high-use Sunnyvale homes wear out and cause silent running or ghost flushes. We replace them with genuine Toto parts and verify the supply line actually delivers what the valve needs.
- Base leaks from mixed unifit adapters on one-piece bowls. Eco Ultramax and Carlyle one-piece Toto toilets need the correct unifit adapter and gasket to seat properly. We’ve corrected prior installs in Sunnyvale where a crew mixed gasket sizes or skipped the adapter entirely, leaving a slow leak at the floor. The fix is exact-fit OEM hardware, not more caulk.
- Galvanized supply lines failing behind Toto fixtures. Sunnyvale’s original galvanized plumbing is at end of life. When we pull a Toto toilet for a remodel or repair, we often find the closet riser corroded behind the wall. Replacing that line with PEX while the wall is open prevents a future flood and keeps the Toto fixture fed with clean, full-pressure water.
Toto Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Here’s what makes Toto work different in Sunnyvale, and why a generic service call doesn’t cover it. In the 94086 and 94087 ranch tracts, original slab-on-grade floors and galvanized supply lines mean a Toto toilet upgrade often requires opening the floor to replace the closet flange and shut-off. That triggers a plumbing permit through Sunnyvale’s building department, where inspectors also review Title 24 and seismic calcs on the same sign-off. A newer infill condo in a neighboring city doesn’t face that permit-and-inspection reality, but a 1962 rancher on an oversized Toto in Mountain View area lot absolutely does. We schedule for it, document it, and make sure the work passes the first inspection rather than the third. On a 1962 ranch in the 94086 core, our crew opened the bathroom floor during a full bath remodel and found the original galvanized closet riser feeding a Toto Drake whose base had cracked from slab movement. We replaced the flange, ran a new PEX supply, and set the Drake on a level patch, then scheduled the Sunnyvale plumbing inspection alongside the Title 24 rough-in sign-off. The owner also asked us to add a dedicated GFCI circuit for a new Washlet C200, which we documented for the permit set.
Toto Models & Products We Service in Sunnyvale
We work on the Toto lines you’re most likely to have in a Sunnyvale home: Drake and Drake II, Eco Ultramax, Aquia (both wall-hung and two-piece), and Washlet seat series including the C100, C200, and S500e. Our parts approach is simple: OEM for anything that affects fit or water control, quality name-brand for everything else. Toto’s tolerances on fill valves, flappers, and Washlet assemblies are tight enough that aftermarket substitutions cause slow leaks and electrical faults, so we don’t use them on core components. For hoses and supply lines, Fluidmaster and brass quarter-turn stops do the job. We keep common Toto parts stocked for fast Sunnyvale turnaround, which matters when a toilet is down and the only other bathroom is a second-floor hall bath that hasn’t been remodeled since 1972. If you’re planning a full bathroom remodel, walk-in shower installation, or new vanities alongside your Toto fixture, we handle all of it under one contract. See our Toto sales & service page for more on how we approach the brand.

What drives the cost in Sunnyvale specifically is whether we’re opening the floor for a flange replacement, running a new supply line, or adding electrical for a Washlet seat, and whether the permit review pulls in Title 24 or seismic scope. Our free estimate covers all of that: we look at the slab, the shut-off, the venting, and the existing rough-in before we quote. Call (877) 752-3868 for a written line-item estimate, not a round number.

FAQs – Toto Construction in Sunnyvale
In most cases, yes. A rocking Toto on a 1950s or 60s Sunnyvale slab almost always traces back to slab settling or a corroded closet flange, not a worn wax ring. We level the floor at the fixture, replace the flange, and reset the Drake on a solid base. Call (877) 752-3868 and we’ll inspect it before you end up with a cracked bowl or worse.
If you’re adding a dedicated GFCI circuit for the Washlet seat, yes, Sunnyvale’s building department will want that electrical work on a permit. If the circuit already exists and you’re only swapping the seat, you can usually proceed without one. We’ll check the existing wiring and tell you which path applies before any work starts.
A constantly running Ultramax is almost always a fill valve or flapper issue, and both are straightforward OEM replacements that cost far less than a new fixture. If the bowl or tank itself is cracked, replacement makes more sense. We’ll give you the repair cost and the replacement cost side by side and let you decide. Call (877) 752-3868 for a straight answer.
Replacing a toilet fixture itself doesn’t require a plumbing permit in Sunnyvale. But if we’re also moving the flange, opening the slab, or rerouting supply lines, that’s a different scope and Sunnyvale’s inspectors will want to see it. We pull permits only for the work that requires them; the rest stays off the books. Call (877) 752-3868 and we’ll scope it correctly.
In older Sunnyvale ranches, mineral scale from municipal water builds up in the Washlet nozzle and valves faster when the bathroom lacks proper ventilation. Weak spray and odor are both symptoms. We descale the unit and replace worn assemblies, and if the bathroom is still unvented, we’ll recommend adding a proper exhaust fan or ventilation upgrade as part of the fix. Call (877) 752-3868 for service.
