Toto Construction in Los Altos, CA | Ashford Contractors
Ashford Contractors provides independent Toto repair in Los Altos Hills and across Los Altos, including installation and replacement, working on everything from a Drake toilet swap to a full bathroom remodel centered on Toto fixtures. We’re not Toto authorized, but we’ve serviced their catalog in hundreds of Los Altos homes, and the failure patterns here run different than they do two towns over. Whether your ranch needs a new wax ring after clay-soil shifting or your Washlet stopped heating, call (877) 752-3868 for a free estimate.
Our Toto work spans the fixture range: Toto sales & service covers everything from Drake and Ultramax II toilets to Washlet electronic bidet seats. And because we’re a full-scope general contractor, the same team that resets your flange can also rebuild the shower, replace the vanity, and pull the permit. Los Altos service area coverage includes 94022, 94023, and 94024.
Why Los Altos Residents Choose Us for Toto Service
One contractor for every system in the bathroom means your Toto in Loyola or Los Altos installation doesn’t become a blame-game between a plumber, a tile setter, and an electrician. We hold the full scope: the rough-in, the waterproofing, the fixture set, and the finish work. Ashford works with Toto, Kohler, Grohe, and Moen on the plumbing side, so your product choice isn’t limited to whatever one sub happens to stock.
Glen Mossier runs the Ashford team, and he’s spent two decades on San Mateo County remodels where plumbing and structure collide. Glen trained in construction technology at Skyline College, and his framing background shows up in how we approach every bathroom scope. Before we set a single Toto repair in Stanford or Los Altos ranch toilet, we’re checking the subfloor, the flange height, and the vent path. Because after a swinging clay-soil season, a bowl that rocks is a leak you won’t see until the drywall starts wicking. We use genuine Toto fill valves, flappers, and Washlet boards where the fixture is worth keeping, and quality aftermarket seals and supply lines where OEM adds nothing but shipping time.

Common Toto Construction Problems We Solve in Los Altos
- Fill and flush valve wear on Drake toilets. Los Altos water runs hard, and on a Toto Drake (CST744 series) that means mineral deposits eat at the fill valve faster than on the coast. Four to six years in, you get phantom running, weak flushes, and a tank that refills in slow motion. We replace the valve and flush the rim jets with the tank pulled, not a chemical shortcut.
- Wax ring and flange failures on original ranch plumbing. Homes built from the 1940s through the 1960s carry cast-iron closet flanges that have spent decades in expansive clay soil. In Los Altos, that flange shifts enough to break the wax seal, the bowl rocks, and water seeps into the subfloor. We reset the flange, install a steel-reinforced repair flange where needed, and seat the bowl properly.
- Washlet electronic failures in high-humidity bathrooms. Toto Washlet S500e and C100 seats have control boards and solenoids that don’t love moisture. In a Los Altos ranch bath with no exhaust fan and wet winters, condensation kills electronics. We test the board first, then tell you honestly whether a repair or a new seat makes sense.
- Slow tank refill and weak siphon on Ultramax II one-pieces. With low-flow-reduced systems and mineral scale building in the rim jet, a Toto Ultramax II loses its siphon pull. You’ll notice the bowl clears slowly and the tank takes forever to refill. We pull the fixture, clear the rim jet properly, and replace the fill valve.
- Rough-in mismatches after remodel layout shifts. Los Altos remodels often move walls and fixtures, and suddenly the drain and supply don’t line up with a 12-inch Toto rough-in. We rework the drain path and reset the supply stub-out before the tile goes down, which is the difference between a clean install and an offset flange buried in your new floor.
Toto Service in Los Altos: What Local Conditions Mean for Your Equipment
Because so many Los Altos lots sit under heritage oaks and redwoods protected by the city’s tree-protection ordinance, we frequently have to pull a Toto toilet and rework the drain and supply rough-in after a remodel layout shifts to keep plumbing inside the existing root zone. That’s a constraint you won’t see cited in most neighboring towns. In Mountain View you can shift a bathroom footprint without an arborist report. In Los Altos, moving a fixture six inches closer to a protected redwood can trigger a redesign and a city review. Practically, this means the Toto work happens inside the root zone constraint: we keep drain lines shallower, use offset flanges only where the code allows, and set fixtures so future service doesn’t require cutting into tree roots.
On a single-story ranch off Covington Road we replaced a rocking Toto Drake in a hall bath where the original closet flange had shifted with the clay soil. Resetting the flange, installing a new wax ring, and adding a steel-reinforced repair flange settled the bowl. In the same scope we installed a Toto Ultramax II one-piece with a properly sealed base and upgraded the vanity to a Ventura cabinet. The customer reported no more phantom running or base leaks.
Toto Models & Products We Service in Los Altos
We work across the Toto catalog that shows up in Los Altos homes most often: the Drake CST744 series, the Ultramax II one-piece, the Aquia dual-flush, and the Washlet S500e and C100 electronic bidet seats. Our parts stance is simple. For fill valves, flappers, and Washlet boards, we use genuine Toto parts where the fixture is worth keeping. For seals, supply lines, and mounting hardware, we use quality aftermarket components that match or beat OEM specs without the wait. When a Washlet’s electronics fail out of warranty in a mid-century bathroom, we’ll walk you through the repair-versus-replace math before you spend a dollar.

FAQs – Toto Construction in Los Altos
Usually yes. If the flange is intact and the subfloor hasn’t rotted, we can pull the old fixture, set a new wax ring, and install your Toto toilet without touching the finished floor. We’ll verify the flange height and check for clay-soil shifting before we set anything. If the flange has moved, we’ll tell you before any tile comes up. Call (877) 752-3868 for a free assessment.
On a Drake in Los Altos, the usual culprit is mineral buildup on the fill valve or a flapper that’s lost its seal to hard-water scale. The tank refills, the flapper leaks, and the cycle repeats. We replace the fill valve with a genuine Toto part, check the flush valve seat, and clear the rim jets while we’re in there. Phantom running is a parts fix, not a fixture replacement.
That depends on the age and the failure point. If a control board or solenoid shorted from bathroom humidity and the seat is over six years old, replacement often makes more financial sense than repair. If it’s a newer Washlet S500e with a simple heating element failure, a genuine Toto part restores it. We’ll diagnose first and give you honest numbers for both paths. Call (877) 752-3868 to book a diagnostic.
Often yes. Tub drains are typically 1-1/2 inches; a walk-in shower needs a 2-inch drain. On a Los Altos ranch with cast-iron lines and clay-soil movement, that means opening the subfloor, reworking the trap, and sometimes repositioning the supply lines for a Toto shower head or hand-spray. We handle the full conversion in-house: framing, waterproofing, tile, and fixture set.
It can. If your remodel moves a bathroom wall or shifts a drain line closer to a protected heritage oak or redwood, the city may require an arborist review. Even if the footprint doesn’t change, excavation within a protected root zone can trigger review. We’ve navigated dozens of these remodels in Los Altos and factor tree constraints into the estimate before you file any paperwork. Call (877) 752-3868 to discuss your specific lot.
