Toto Construction in Tiburon, CA | Milpitas Construction
We provide independent Toto fixture installation, repair, and replacement across Tiburon, and the one thing that separates our Toto work here from anywhere else is this: hillside lots and salt air change everything. A Toto Neorest that works flawlessly in a flat Sacramento subdivision behaves differently when it’s craned over a Belvedere roofline and asked to tolerate marine-layer humidity year-round. That’s the work we do every week, and we do it with OEM parts and a straight answer. Call (877) 752-4194 for a free estimate on any Toto project in Tiburon.
Why Tiburon Residents Choose Us for Toto Service
Ken Stafford, owner of Milpitas Construction, didn’t learn Toto fixtures from a brochure. He learned them the way you learn anything on the Bay Area’s coastal hills: by fixing what salt air, shifting foundations, and hard water break. We’ve replaced fill valves in Old Tiburon cottages where the original plumbing dates to the 1930s, and we’ve wired GFCI circuits for Washlet seats in mid-century view homes that never had a receptacle behind the toilet. We stock Toto sales & service parts locally, so a running Drake or a dead Neorest control board doesn’t mean waiting a week for a warehouse shipment. We’re independent. That means we diagnose the actual failure, not just what a warranty manual assumes. And we tell you when a repair makes sense and when you should put your money into a new high-efficiency Toto instead.

Common Toto Construction Problems We Solve in Tiburon
These are the five failure patterns we see most often in Tiburon service area homes:
- Running or weak-flushing toilets from hard water scaling. Tiburon’s water supply leaves mineral deposits on Toto fill valves and flush towers. The Eco Ultramax and Drake are both prone to slow, incomplete flushes when calcium builds up on the tower seal. We clean or replace with OEM Toto parts, not aftermarket knockoffs that fail in six months.
- Rocking toilets and repeated wax ring failures on pier-and-grade foundations. Many Tiburon homes sit on post-and-pier foundations that move a fraction of an inch with seasonal soil shifts. That movement shears wax rings and loosens closet bolts. We re-level the subfloor, shim the flange properly, and set the toilet with a reinforced ring so it stays put.
- Closet flange misalignment on sloped floors. Floors in older hillside cottages aren’t level. When a flange sits proud or recessed because the floor has settled, even a fresh wax ring won’t seal. We install flange extenders or stainless repair rings and test with a leak-down procedure before we leave.
- Neorest and Washlet electronic corrosion from salt air. The marine layer that rolls over Richardson Bay puts salt and moisture into every bathroom that opens a window. Toto’s electronic boards don’t love it. We see control board corrosion, sensor failures, and power supply issues more often in Tiburon than anywhere else in Marin.
- Skirted toilet installations where rough-in measurements are off. Toto’s skirted models, especially the Aquia, need precise rough-in dimensions. In century-old bathrooms where walls aren’t square and floors slope, we adjust the rough-in, move supply lines, and make sure the mounting system lands flush against the wall.
Toto Service in Tiburon: What Local Conditions Mean for Your Equipment
Here’s the thing most contractors won’t tell you about working on Toto fixtures in Tiburon: the logistics of the lot often cost more than the fixture itself. In Belvedere and Old Tiburon, many homes sit on hillside streets with no driveway access at all. A Toto Neorest ships in a crate that weighs close to 90 pounds. You can’t wheel that up a flight of stairs on a hand truck without risking the unit and the person carrying it. We’ve craned toilets over rooflines on more than one Belvedere job, and we’ve hand-carried skirted Aquias up switchback staircases where a truck couldn’t get within a hundred feet of the front door. That reality changes scheduling, changes pricing, and changes how we plan Home Remodeling – Tiburon projects from the first site visit. On a steep lot in Belvedere, we replaced a 15-year-old Toto Drake in a master bath. The pier-and-grade foundation had shifted slightly, leaving the closet flange 1/8-inch below the finished tile and the wax ring failing every few months. We shimmed and re-leveled the subfloor, installed a stainless-steel flange extender, and set a new Toto Ultramax II with a reinforced wax ring. That was three years ago, and the toilet hasn’t leaked since. Build it right the first time – the Bay Area doesn’t give you a free pass on shortcuts.
Toto Models & Products We Service in Tiburon
We work on the full range: Drake, Eco Ultramax, Aquia, and Neorest, including Washlet seats and integrated electronic bidets. For fill valves, flush towers, and electronic boards, we use OEM Toto parts. Aftermarket parts save a few bucks and fail fast, especially with Tiburon’s hard water and humidity. For older toilets with cracked porcelain, corroded internals, or multiple failed components, we usually recommend replacement with a new high-efficiency Toto rather than stacking repair costs. We can also handle full bathroom remodels, walk-in shower installations, and tile and flooring work around your Toto fixtures, working as your General Contractor – Tiburon so the finished room works as one system.

FAQs – Toto Construction in Tiburon
Yes. We run a new GFCI-protected circuit from the nearest accessible junction box or panel to a recessed outlet behind the toilet, which is the correct installation for any Toto Washlet or Neorest unit operating near moisture. Call (877) 752-4194 and we’ll inspect your bathroom and quote the electrical work as part of the install.
Yes, we diagnose and repair Neorest control boards, power supplies, and sensor assemblies, and we carry common OEM replacement parts for faster turnaround in Tiburon. Power outages combined with salt-air humidity are a common culprit for Neorest faults on the peninsula. Call (877) 752-4194 and we’ll schedule a diagnostic visit.
In most Tiburon homes, the cause is mineral scaling on the fill valve or flush tower seal, which prevents a complete seal and lets water trickle continuously from the tank to the bowl. We replace the affected parts with OEM Toto components and clean the valve seat so the problem doesn’t return in a few months. Call (877) 752-4194 for a repair estimate.
Yes, we relocate waste lines, venting, and supply lines as part of a full bathroom remodel, and we handle the subfloor work required when a hillside home’s framing complicates the new drain route. Moving a toilet on a pier-and-grade foundation takes planning, but it’s routine for our crews in Tiburon. Call (877) 752-4194 to discuss your layout.
