Toto Construction in Brea, CA | Millwright Builders
We install and service Toto toilets, Washlets, and lavatory fixtures across Brea, and we do it independently – no manufacturer affiliation, no dealership badge. The thing that makes our Toto work here different is that we know exactly which failures show up in which Brea neighborhoods: hard-water scale killing Washlet wands in the flatland ranch tracts, and Santa Ana dust fouling electronics in Carbon Canyon. If your Toto is acting up or you’re planning a bath remodel around one, call (866) 925-0334 and we’ll take a look.
Why Brea Residents Choose Us for Toto Service
We’ve pulled apart Toto fill valves, flappers, and bidet-seat boards in kitchens and bathrooms all over Brea – from the 1960s-70s tracts east of Brea Blvd up into the custom hillside homes of Olinda Village. That’s the difference between a contractor who read a spec sheet and one who’s actually diagnosed a sticky tower-style fill valve on a 2004 Drake II in a 92821 rancher. We’re an independent construction and remodeling company, not a Toto authorized service center, and we don’t need to be – the work speaks for itself.
Noel Castañeda, our owner, built his reputation on framing that doesn’t rack and finishes that hold up. He’s the same person who insists we stock genuine Toto OEM nozzle assemblies and inlet screens rather than waiting a week for parts when a Washlet in Brea stops cleaning itself. For us, Toto sales & service isn’t a sideline – it’s part of how we approach bath construction and remodel work across Orange County.

Common Toto Construction Problems We Solve in Brea
- Washlet wand and nozzle clogging from hard water. Brea’s municipal supply leaves mineral scale behind, and the self-clean cycle on C100, C200, and S-series Washlets eventually loses the fight. We pull the seat, swap the OEM nozzle assembly and inlet screen, and the seat runs like new instead of pushing a full replacement nobody should have to buy at year six.
- Phantom refills and running toilets on Drake and Ultramax installs. The tower-style fill valves on 1990s-2000s Toto toilets get sticky, and owners hear the tank topping off every twenty minutes. It’s a quick valve-and-flapper fix, and it’s common enough in the flatland tracts of 92822 that we keep the parts on the truck.
- Tank-to-bowl gasket seeps on one-piece Ultramax II units. Brea summers run hot, and thermal cycling dries that seal until it weeps onto the floor. We’ve caught more than a few before they ruined the flooring underneath, especially in older ranch homes where original wax rings and gaskets have aged out together.
- Santa Ana dust in Carbon Canyon and Olinda Village Washlet electronics. Wind events push fine dust into seat housings and vent openings. The boards don’t love it. We’ve cleaned and re-seated enough of these in hillside homes to know it’s a recurring local factor, not a one-off defect.
- Water damage under the bowl from failed wax seals. In bathrooms with original 1970s flooring, a failed wax ring on a Toto can sit undiscovered until the tile or hardwood starts cupping. We re-set the toilet on a fresh seal and repair the damage before it spreads to the subfloor.
Toto Service in Brea: What Local Conditions Mean for Your Equipment
Here’s the part most generic Toto pages miss: Brea’s flatland 1960s-70s ranch tracts east of Brea Blvd often still hide original galvanized supply lines and undersized electrical panels. When we set a Washlet or remodel a bath around a Toto in one of those homes, we frequently have to run a dedicated circuit and re-pipe before the fixture ever goes in. A Carbon Canyon custom home with a modern 200-amp panel won’t trigger that step. A 1968 rancher in 92823 almost certainly will. Build it right the first time – the Peninsula weather will find out if you didn’t. (And in Brea, so will the inspector.)
Toto Models & Products We Service in Brea
We work on the full range of Toto fixtures you’re likely to find in Brea homes: Drake and Drake II two-piece elongated toilets, Ultramax II one-piece units, EcoPower and EcoPromenade high-efficiency models, and the C100, C200, and S-series Washlet electronic bidet seats. For Washlets and electronic seats, we lean on genuine OEM parts – nozzles, inlet screens, control boards – because aftermarket electronics are a false economy that often don’t fit the seat housing. For standard toilets, a quality fluid-master-style fill valve and a real flapper will outlast the rest of the toilet, and that’s the honest repair we recommend. When a 20-year-old one-piece has a cracked tank or a dead Washlet board approaching the cost of a new unit, we’ll tell you to replace it rather than throw money at it. Our honest advice comes free; the estimate does too.

FAQs – Toto Construction in Brea
No. We’re an independent construction and remodeling company that installs and services Toto fixtures across Brea, but we have no manufacturer authorization, sponsorship, or endorsement from Toto. You don’t need a Toto badge to diagnose a sticky Drake fill valve or replace a Washlet inlet screen – you need field experience, and that’s what we bring.
Yes, for electronics and bidet seats we use genuine Toto OEM parts – nozzles, inlet screens, and control boards. Aftermarket Washlet parts are a false economy; they rarely fit the housing correctly and fail sooner. For standard toilets, we’ll recommend quality aftermarket fill valves and flappers that outlast the original, because that’s the honest repair. Call (866) 925-0334 and we’ll tell you what your Toto actually needs.
Most fill valve, flapper, and gasket repairs finish the same visit, usually within an hour or two once we’re on site. Washlet electronic repairs may take a second visit if a control board needs to be ordered. Bath remodels built around a Toto fixture typically run one to three weeks depending on scope. We’ll give you a written timeline before work starts.
We service Drake and Drake II two-piece toilets, Ultramax II one-piece units, EcoPower and EcoPromenade high-efficiency models, and all Washlet electronic bidet seats including the C100, C200, and S-series. If you’re not sure what model you have, send us a photo and we’ll identify it before we arrive.
A small bathroom remodel with a Toto upgrade in Brea typically runs $5,000 to $12,000, while a full bathroom remodel with a Toto fixture re-set or new Washlet lands between $9,000 and $28,000. We also provide Toto service in Fullerton. Older ranch homes may add costs for galvanized re-pipes or panel upgrades before the fixture can be installed. Call (866) 925-0334 for an exact quote – estimates are free.
