Toto Construction in Sunnyvale, CA | Workshop Contractors
We’re an independent construction crew that handles Toto installation and repair work across Sunnyvale, California. We pull dead Drakes from 1950s ranch bathrooms, swap out failing Washlet seats, and re-set one-piece Neorests on slab foundations that have shifted over sixty years of Silicon Valley ground movement. The one thing that makes our Toto work different here is that we’re not authorized by Toto, which means we’ll tell you straight whether a fixture is worth repairing or whether you’re better off putting that money toward a full bathroom remodel on your 94087 lot. Call (844) 384-3361 and we’ll come look at it.
Why Sunnyvale Residents Choose Us for Toto Service
We’ve been inside enough Sunnyvale bathrooms to know which Toto models hold up under this city’s water and which ones don’t. The Drake and Eco Ultramax lines are workhorses, but Sunnyvale’s municipal water runs hard enough to scale fill valves within a few years on the older ranches in 94086 and 94087. A plumber who only sees Toto in Cupertino new construction won’t catch that pattern. Our crews have been through the 94087 orchard tracts enough times to recognize a ghost-flushing Drake as a scaled OEM fill valve before we’ve even pulled the tank lid.
One of the reasons our Toto work earns repeat calls is Noel Figueroa’s approach to the trade. Noel learned the fundamentals through Chaffey College’s construction technology program, where he was on job sites before he could legally rent a truck, and he’s spent the decades since working with the kind of hands-on precision that shows in square framing and tile that lines up at the grout joint. Build it right the first time. The second time costs twice as much and nobody’s happy about it. That applies to a re-set Neorest as much as it does to a full addition.

Common Toto Construction Problems We Solve in Sunnyvale
- Scaled fill valves and running toilets. Sunnyvale’s municipal water is hard, especially in the older 94086 and 94087 neighborhoods. The original Toto Drake fill and flush valves in those 1950s and 60s ranch baths scale up internally, which leads to ghost-flushing and tanks that run long before the bowl shows any visible wear. We replace the internals with Toto OEM fill valves, flush towers, and gaskets, because aftermarket parts fit loosely and create the same weak-flush complaints that brought us out in the first place.
- Racked closet flanges on tight infill lots. When a teardown-and-rebuild happens next door in Sunnyvale, the vibration and grade change on those small parcels racks the older closet flanges. A Toto one-piece that sat perfectly level for 40 years suddenly rocks at the base and weeps. This one is so specific to Sunnyvale’s rebuild economy that we now check flange level as a matter of course on any Toto service call in 94087.
- Dead Washlet and Neorest circuits on non-GFCI wiring. In the older orchard-tract homes, Washlet and Neorest units were often retrofit onto bathroom circuits that have no GFCI protection and no dedicated supply. The seats fail electrically or trip repeatedly, and the actual fix is rough-in work, not a new seat. We add the dedicated circuit, bring the wiring to code, and then install the Washlet properly.
- Wax ring failures on mid-century slab floors. The 94087 orchard tracts were built on concrete slabs, not raised foundations. When a toilet gets pulled for a remodel, the old wax ring fails and the flange is often cracked. A Toto that flushed fine on the old ring leaks the moment it’s re-set. We address the flange and slab repair before the new fixture goes in.
- Toto Neorest control board and bowl failures. On a newer Neorest, a failed control board or cracked bowl usually isn’t worth the repair cost. We’ll give you the honest replacement math and help you decide between a new Neorest, a simpler Drake, or a full bathroom remodel that reconfigures the rough-in entirely.
Toto Service in Sunnyvale: What Local Conditions Mean for Your Equipment
In Sunnyvale’s 94087 orchard tracts, the same block routinely has an original 1950s ranch sitting next to a brand-new three-story build. That adjacency creates a construction condition you won’t find in most other Bay Area cities, and it directly affects Toto toilets in the older houses. When a neighboring lot gets regraded for a rebuild, the older house’s slab can settle slightly, and a toilet flange that was level for sixty years is suddenly sitting a half-inch out of level. The Toto fixture rocks at the base, the wax ring compresses unevenly, and within a month you’ve got a slow weep at the floor. On a recent 94087 ranch block off the old orchard tracts, we opened a bathroom for a small remodel and found the original Toto Drake rocking on a cracked closet flange. The slab had settled where the neighboring lot had just been regraded for a rebuild. We cut out the old flange, set a new PVC flange on the repaired slab, replaced the wax ring and OEM fill valve, and re-set the toilet level against the new tile before we framed the curbless shower. That’s the kind of layered repair that only makes sense when you’ve seen how Sunnyvale’s teardown economy works from inside a 1960s bathroom.
We’re an independent Toto service provider, not a manufacturer-authorized dealer. That means we can tell you the truth about parts availability and repair economics without a dealer contract influencing the recommendation. Toto sales & service work in Sunnyvale is something we do as part of our broader bathroom remodeling scope, which also covers full and small bathroom remodels and walk-in shower installations.
Toto Models & Products We Service in Sunnyvale
We work on the Toto model families that show up most in Sunnyvale’s 94086, 94087, 94085, and 94089 ZIP codes. The two-piece Drake series, CST743 and CST744, are the most common toilets in the older ranch stock. The Eco Ultramax MS854114 series one-piece shows up in many mid-century baths that were updated in the 1990s. Washlet seats, particularly the S550e and earlier C-series, are everywhere in Sunnyvale given the tech-adjacent buyer profile. The Neorest integrated smart toilet shows up in the newer two-story rebuilds. We use Toto OEM fill valves, flush towers, and gaskets for internals, and we stock the common OEM rebuild kits locally so a Drake repair in Sunnyvale doesn’t wait on a parts shipment. On a 15-to-25-year-old Drake, we usually recommend repair. On a Neorest with a failed control board or cracked bowl, we’ll walk you through the replacement math honestly.

FAQs – Toto Construction in Sunnyvale
On a 15-to-25-year-old Drake, we almost always recommend repair first. The running is usually a scaled OEM fill valve, which is a quick parts replacement and far cheaper than a new fixture. The exception is if the bowl has hairline cracks or the flange beneath is failing, which we’ll check during the visit. Call (844) 384-3361 and we’ll tell you which side of that line your toilet is on.
Yes, and this is one of the most common calls we get in the 94087 orchard tracts. When a neighboring lot is regraded and a new two-story foundation goes in, the older house’s slab can settle, which shifts the closet flange out of level. A Toto one-piece that was flat for decades starts rocking and leaking at the base. We fix the flange and slab, then re-set the fixture level.
In most cases, yes, but the rough-in matters. The older orchard-tract baths in Sunnyvale were wired before GFCI protection became standard, and a Washlet needs a dedicated, protected circuit to run reliably. We’ll add the circuit and bring the wiring to code before we install the seat. Call us for an assessment, and we’ll tell you exactly what your bathroom needs for a Washlet retrofit.
The most common cause we see in Sunnyvale is the control board failing, often related to power fluctuations on an older circuit. After a few years, a Neorest with a failed board typically isn’t worth the repair cost. We’ll give you an honest comparison of replacement options, from a new Neorest to a simpler Drake or Eco Ultramax that will last decades with minimal upkeep. Call (844) 384-3361 and we’ll walk you through the numbers.
If it’s a straight fixture swap, no permit needed. If we’re moving the rough-in, touching the drain line, or adding a circuit for a Washlet or Neorest, then yes, Sunnyvale requires permits, and we pull them. We’ve navigated Toto in Santa Clara County and Valley Water requirements enough times to know what triggers review and what doesn’t. We handle the paperwork as part of the job.
