Toto Construction in Irvine, CA | Daly City Construction
We provide independent Toto service across Irvine, from Woodbridge and Northwood to Turtle Rock, Westpark, and the newer Great Park villages, plus North Tustin Toto service. The one thing that makes Toto work here different is the slab under your house: virtually every Irvine home sits on a post-tension cable foundation, and any fixture move or bath remodel has to be planned around cable locations before we cut concrete. That changes how we sequence a Toto rough-in, and it’s why a straightforward toilet swap in Irvine sometimes isn’t so straightforward. Call (866) 505-5254 and we’ll walk you through what your project actually needs.

Why Irvine Residents Choose Us for Toto Service
We work on Toto fixtures every week across Irvine’s master-planned villages, from original 1990s builder-grade Drakes to newer Washlet and Neorest installs, and we know how those fixtures behave on post-tension slab floors inside HOA-governed tracts. We are an independent Toto service provider – not authorized, sponsored, or endorsed by Toto – and we say so plainly. What we bring instead is time on the job. Noel Cabrera grew up in Daly City’s Westlake district watching his uncle re-frame a garage, and he trained in construction technology before putting in years on residential and light commercial jobs across San Mateo and San Francisco counties. His signature line on any job, Toto work included: “Tell me what the house needs, not what you think it needs – then we’ll figure out the right fix.”
We stock genuine Toto OEM fill valves, flappers, wax rings, and Washlet inlet screens locally, so most Irvine service calls don’t wait on a parts shipment. We’re not authorized by Toto, but we know their fixtures well enough to fix them right the first time – and to tell you honestly when a repair ends and a replacement makes more sense.

Common Toto Construction Problems We Solve in Irvine
- Wax-ring and closet-flange failures on slab-shifted tract baths. A post-tension slab can move a fraction of an inch over decades, and a Toto Drake that once sat flat starts rocking and weeping at the base. We see this a lot in 1990s-2000s two-story tracts like Woodbridge and Westpark. The fix usually means re-leveling the flange, not just swapping the wax ring.
- Washlet and Neorest control boards fouled by Irvine’s hard municipal supply. Irvine water carries enough mineral content to clog inlet screens and fritz control boards, which shows up as weak spray or a dead seat. The screen is cheap to clean or replace; the board is the expensive part, so we check the screen first.
- Phantom refills on older Ultramax and Drake tanks. A fill valve or flapper that’s worn out will let the tank refill every few minutes, and homeowners often think the bowl itself is the problem. Sometimes the supply stop at the wall has scaled shut. It’s almost never the bowl.
- One-piece skirted bowls that no longer sit flat after slab or tile shift. On village-edge homes where the ground settles unevenly, a skirted Toto can crack its seal and leak onto the floor. The fix involves re-shimming and re-sealing – sometimes re-flanging. We don’t patch over structural settlement.
- Builder-grade Drakes that predate Washlet-ready circuits. Plenty of Irvine bathrooms from the 1990s lack a GFCI outlet behind the toilet, which stops a Washlet install cold. We run the dedicated circuit as part of the job, and we handle the HOA submittal if your village’s architectural committee cares about exterior vent changes.
Toto Service in Irvine: What Local Conditions Mean for Your Equipment
Nearly every house in Irvine was built after 1970 on a post-tension cable slab, which is the single biggest difference between Toto work here and the same job with Toto service in Santa Ana or Orange. The cables run through the concrete under tension. Cut one, and you’ve turned a toilet swap into an engineered repair. That’s why, before any Toto rough-in that involves moving a drain or cutting the slab, we scan for cables with ground-penetrating radar. On undisturbed ground at village edges or near the Great Park, the city can also require a paleontological or archaeological monitor on that same excavation – Irvine sits on fossil-rich Pleistocene deposits – so our Toto rough-in is sequenced around cable scan and monitor scheduling, not the other way around. The practical takeaway: a Toto install or bath remodel in Irvine has a planning step that a flat-lot swap in a prewar neighborhood doesn’t, and a contractor who ignores it is gambling with your foundation. We don’t.
Toto Models & Products We Service in Irvine
We service the full range of Toto lines you’re likely to find in Irvine tract homes and remodels: the Toto Drake and Drake II two-piece, the Ultramax II one-piece, the Aquia dual-flush, and the Washlet seats and Neorest integrated toilets that are increasingly common in village bath upgrades. For parts, we use genuine Toto OEM components wherever the part is still in production – fill valves, flappers, wax rings, Washlet inlet screens. We’ll use quality aftermarket only for commodity items like supply lines and stops, where the OEM markup buys you nothing. A Toto toilet is worth repairing for a long time. A fill valve or flush tower swap is far cheaper than a new fixture, so we recommend replacement only when the bowl or tank is cracked, the flange is unrepairable, or you want to move to a Washlet or Neorest that the existing circuit can’t support.

FAQs – Toto Construction in Irvine
No. We’re an independent Toto service provider in Irvine, not authorized, sponsored, or endorsed by Toto. We use genuine OEM parts and we know the fixtures well, but we’re not a Toto company. If you need Toto warranty work specifically, check with Toto directly.
Genuine Toto OEM fill valves, flappers, wax rings, and Washlet inlet screens wherever the part is still in production. We’ll use quality aftermarket only for commodity items like supply lines and stops.
Most repairs – a fill valve, flapper, wax ring, or inlet screen – go same-day. A bath remodel with a new Toto rough-in takes longer because we sequence the work around post-tension slab scanning and, on some Irvine sites, a city-required paleontological or archaeological monitor. Call (866) 505-5254 and we’ll give you a real timeline for your specific village and scope.
We service the Toto Drake and Drake II, Ultramax II, Aquia dual-flush, and Washlet seats and Neorest integrated toilets. If it’s a Toto fixture in an Irvine tract home, we’ve likely worked on that model recently.
Usually not. In a 1990s Woodbridge two-story, the upstairs hall bath had a Toto Drake that rocked and left a rust ring on the tile (unlike a recent Toto repair in Aliso Viejo we handled), and the homeowner wanted a curbless walk-in shower plus a new Washlet-ready toilet. We scanned the post-tension slab before any penetration, found the cables clear of the new drain, re-set a level closet flange with an OEM wax ring, ran a dedicated GFCI circuit for the Washlet, and finished the shower with a frameless enclosure. The village’s architectural committee signed off on the bath vent and window details, and the final plumbing inspection passed on the first visit. You can keep your Toto and still get the shower you want. For an exact number on your tract bath, call (866) 505-5254.
