Toto Construction in Mount Hermon, CA | San Bruno Construction
We’re San Bruno Construction, an independent Toto service provider working throughout Mount Hermon, and we handle everything from swapping a failing Washlet control board to remodeling an entire bathroom around existing Toto fixtures. What makes our Toto work different in Mount Hermon is that we plan for redwood-canopy moisture and defensible-space venting rules from the first site visit, not as an afterthought. If you need Toto repair, replacement, or a full bath build in the 95041 ZIP, call (866) 472-1908 for a free estimate.
Why Mount Hermon Residents Choose Us for Toto Service
Noel Carvalho, our owner, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and think through load paths before a single tool comes out of the truck. Over two-plus decades, he’s run residential projects across San Mateo County and the Santa Cruz Mountains, including bathroom remodels where Toto in Ben Lomond and nearby areas meant fixtures had to work with old pier-and-beam floors and damp, tree-shaded air.
We maintain a full Toto sales & service capability that covers the original 1980s Washlet units through today’s high-efficiency toilets and touchless faucets. Our crew knows the difference between a Toto OEM fill valve and a cheap aftermarket copy, and we stock genuine parts for critical components. For Mount Hermon homeowners, that means fewer return trips, faster diagnostics, and repairs that hold up through the fog season. We’re not a manufacturer-authorized shop, and we’ll tell you that plainly. We’re independent. That independence means we recommend the right repair, not the one Toto’s warranty department prefers.

Common Toto Construction Problems We Solve in Mount Hermon
- Washlet control boards that corrode early. Mount Hermon’s foggy, high-humidity air gets into unheated cabins and condenses inside the electronics bay of Toto S550e and C200 seats. We’ve replaced dozens of boards that failed from moisture, not age, and we always check the venting setup before installing a new one.
- Tank-to-bowl gasket leaks on one-piece Toto models. The Ultramax MS854114 and similar smooth-sided toilets hide a small leak at the gasket for months. Thermal cycling between cold mountain nights and warm afternoons stretches and shrinks that gasket until water seeps into the subfloor. By the time a Mount Hermon homeowner notices, the redwood subfloor often needs repair too.
- Washlet power supplies fried by undersized wiring. Older cabins in Mount Hermon frequently run on 1960s or 70s electrical panels with thin-gauge branch circuits. A Toto Washlet draws more than a standard outlet expects, and voltage fluctuations on those pier-and-beam floors burn out power supplies. We check the circuit before we mount the seat.
- 1.28 GPF toilets backing up due to root intrusion. Redwood roots are relentless. They find aging sewer laterals along Mount Hermon’s slopes and create backup pressure that damages the flush tower seals inside high-efficiency Toto Drakes and other models. We’ll diagnose whether the problem is the toilet or the lateral before we sell you parts you don’t need.
- Blocked bath fan ducting that ruins Washlet electronics. Defensible-space clearing is mandatory in Mount Hermon’s high fire-severity zone, but clearing debris sometimes gets pushed against exterior wall vents. A blocked vent traps damp air in the bathroom, and the Washlet control board is usually the first casualty. We’ve seen this exact sequence more times than we can count.
Toto Service in Mount Hermon: What Local Conditions Mean for Your Equipment
Mount Hermon sits under a dense redwood canopy and inside a high fire-severity zone, which creates a code balance most neighboring towns never deal with. Bathroom vent fans have to move serious damp air out of the house, but every exterior penetration has to respect defensible-space clearance and fire-safe construction rules. We recently replaced a failed Toto Washlet S550e in a 1960s redwood cabin off Conference Drive where the original vent fan had been blocked by clearing debris, corroding the control board. Our crew installed a new OEM board and rerouted the bath fan ducting to exhaust above the roof line, restoring the bidet and preventing repeat moisture damage. That project is a perfect example of why Lompico Toto service and work throughout these mountains requires more than parts swapping. You have to see the whole building, not just the fixture. Good construction doesn’t announce itself – it just works, year after year.
Toto Models & Products We Service in Mount Hermon
We service the full Toto lineup found in Mount Hermon homes: the Drake two-piece CST743 series, the Ultramax one-piece MS854114, the S550e and C200 Washlet seats, and EcoPower touchless faucets. For critical components like fill valves, flappers, and Washlet boards, we stock genuine Toto OEM parts. For supply lines and seals where Toto’s pricing adds no durability benefit, we use quality aftermarket equivalents and tell you which is which. If an older Toto fixture shows multiple electronic failures, we’ll lay out the repair cost next to a modern replacement before recommending either path. Some Mount Hermon cabins still run original 1980s Washlets that aren’t worth sinking money into.

FAQs – Toto Construction in Mount Hermon
Yes, and we do it regularly. The key is diagnosing why the seat failed before installing a new one. In Mount Hermon, that usually means checking the vent fan, the circuit wiring, and whether the cabin has proper humidity control. Skip those steps and the new board fails the same way the old one did. Call (866) 472-1908 for an inspection.
On Toto Drakes and similar two-piece models, a running toilet is usually the flapper warping or the fill valve diaphragm wearing out. But in Mount Hermon, low water pressure from hillside supply lines can mimic a fill valve problem. We test the fixture and the supply before replacing anything. The fix is often a $15 part, not a new toilet. Call (866) 472-1908 and we’ll sort it out.
We do, and we’ve done it many times. Pier-and-beam floors move with the seasons, so we shim and anchor Toto toilets and Washlets to handle that movement without cracking the base or loosening the flange. On older redwood cabins, we check the subfloor before we set anything, because hidden rot from a long-forgotten leak is common, so Toto repair in Felton and Mount Hermon both need that extra care.
It depends on the lateral. Toto’s 1.28 GPF models move less water, which is fine when the drain has proper slope. But if redwood roots have intruded into your sewer lateral, the reduced flow can leave waste sitting against the roots and backing up. We’ll scope the line if there’s a history of clogs before we recommend which Toto model fits your plumbing. Get an exact assessment by calling (866) 472-1908.
Yes, and we do full bathroom remodels in Mount Hermon that keep your existing Toto fixtures right where they are. We’ll design the tile, shower, and vanity around the Toto units, upgrade the venting to meet fire-safety and moisture codes, and make sure the final result meets county inspection standards. The Toto fixtures stay. Everything around them gets the upgrade. Call (866) 472-1908 for a free design consultation.
