Toto Construction in Lompico, CA | San Mateo Construction
We’re San Mateo Construction, and we install, service, and repair Toto toilets, washlets, and bathroom fixtures throughout Lompico. The thing that separates our Toto work here is simple: we know how private wells, pier-and-post floors, and Santa Cruz County septic review affect every fixture decision. Call (855) 901-7266 for a free estimate on any Toto install, repair, or full bathroom remodel in Lompico.
We’re an independent contractor, not a Toto dealer or authorized agent. That means our recommendation is whatever actually fits your bathroom and your water supply, not whatever’s on a sales sheet. If you’re replacing a toilet, converting a tub to a shower, or remodeling an entire bath, Toto sales & service is part of the scope we handle under one contract.
Why Lompico Residents Choose Us for Toto Service
Noel Carrington grew up in Baywood, pouring concrete footings with his father on weekends, and spent decades running residential and commercial jobs across San Mateo County before leading our crew. We’ve worked on enough owner-built mountain cabins to know that a Toto one-piece needs a different install approach on a flexing pier-and-post floor than it does on a slab in town. That’s not a sales line; it’s what separates a toilet that stays sealed from one that rocks and shears its wax ring within a year.
Folks in Lompico call us because we stock genuine Toto OEM fill valves, flappers, canister seals, and washlet filters, and because we show up knowing the roads — and because we also handle Toto in Brookdale and nearby communities. Lompico’s single-lane private drives with no turnaround mean we plan deliveries and dump runs around what the truck can actually reach, not what the supplier assumes it can. We’re also fully licensed and insured, and every job gets a written line-item quote before we touch a wrench. Tell me what you actually need, and we’ll figure out the right way to build it.

Common Toto Construction Problems We Solve in Lompico
- Weak flush and a tank that never stops refilling on Drake and Aquia models. Lompico’s private wells push hard mineral water through fill valves and flush valves, and the scaling builds up fast. The symptom is usually a weak flush and a refill that runs for five minutes after every use. We replace the G-Max or Tornado fill valve and flapper with genuine Toto parts and the toilet flushes like new.
- Washlet seats that gum up or lose pressure. Low-yield well pumps and gravity-fed storage tanks create pressure swings that stress washlet inlet filters and electronic valves. The S550e, C5, and K300 are all susceptible when the pressure tank short-cycles. We clean or replace inlet filters and check the supply line pressure before blaming the seat.
- One-piece Ultramax II and skirted models cracking at the base or leaking at the tank seal. Lompico cabins sit on slopes with pier-and-post foundations that flex seasonally as the ground drinks winter rain and dries in summer. A toilet that rocks slightly will shear the wax seal or crack the skirted base over time. We shim and strap the flange so the fixture stays put.
- Phantom running through damp winters. Cabins that sit cold and damp from November through March cause flappers and canister seals to stiffen and degrade. On a limited well supply, a running toilet wastes water you can’t afford to lose. We replace with Toto-spec parts and test the flush before we leave.
- Toilets that need to move but the septic system may not cooperate. Adding or relocating a Toto toilet in a Lompico remodel can trigger a Santa Cruz County septic-capacity review. We handle the fixture spec and documentation as part of the permit packet so the county sees the actual gpf and flow numbers before the permit clears.
Toto Service in Lompico: What Local Conditions Mean for Your Equipment
Here’s the thing most Toto service pages won’t tell you, because they’re written for flatland suburbs with municipal sewer: in Lompico, no municipal sewer exists. Every bathroom remodel that adds or relocates a toilet runs through Santa Cruz County septic review, not a city building department. That means when you’re replacing an old Toto Drake with a dual-flush Aquia or adding a Washlet-equipped toilet, the county wants the fixture spec in the permit packet before it will sign off. We size the toilet and document its gallons-per-flush as part of the septic conversation, not after the fact. It’s a small step that saves weeks on the back end.
That’s the Lompico-specific reality. A contractor who works mostly in San Mateo or Burlingame may never have touched a septic capacity worksheet. We have, and we know which Toto models keep the county happy versus which ones trigger additional review. If you’re on a low-yield well near the Lompico basin, a 1.28 gpf Drake or a dual-flush Aquia reads differently to the county than a high-flow model from the 1990s. We’ll walk you through it before you buy a fixture you can’t permit.
Toto Models & Products We Service in Lompico
We work on Toto’s two-piece Drake line (CST743 and CST776 series with G-Max or Tornado flush), the Aquia dual-flush two-piece, the Ultramax II one-piece, the Vespin II, and the full Washlet and Washlet+ seat line including the S550e, C5, and K300. We also install and service Toto bathroom faucets, shower valves, and tub fillers as part of broader bathroom work.
Parts matter with Toto. Their tolerances are tight, and aftermarket flappers are the number one cause of repeat running-toilet callbacks we see. We use genuine Toto OEM fill valves, flappers, canister seals, and washlet filters because anything else creates a callback neither of us wants. When a part is discontinued, we source a Toto-spec equivalent and note it on the invoice. If the bowl and tank are sound, we repair; Toto’s vitreous china outlasts nearly everything around it. We only recommend replacement when a skirted or one-piece base is cracked or the washlet electronics are beyond economical repair.

AfterToto Service Pricing in Lompico
Here’s what Toto-related work typically costs in the Lompico area. These are project-level ranges, not fixed bids; your price depends on your cabin’s plumbing condition, floor structure, and what the county septic review requires.
| Service | Typical Range |

What drives the number in Lompico is usually floor condition and access. If the pier-and-post floor needs shimming and strapping before the toilet goes down, that adds labor but prevents the rock-and-leak cycle that costs you more later. A free estimate includes a look at your existing plumbing, floor, and what the septic review might require. Call (855) 901-7266 and we’ll give you an exact number in writing.

FAQs – Toto Construction in Lompico
Yes, but it depends on your pressure consistency. Washlets need steady inlet pressure, and a short-cycling pressure tank or a low-yield well can cause the seat’s internal valves to chatter and the electronics to fault out. We check your pressure tank, supply line size, and shutoff before installing a Washlet, and we’ll tell you honestly whether a pressure tank adjustment or a larger supply line is needed first. Call (855) 901-7266 for a free estimate on the full setup.
It can, yes. Lompico has no municipal sewer, so Santa Cruz County reviews bathroom remodels for septic capacity when a toilet is added, relocated, or changed to a different flow rate. Moving from an older high-flow toilet to a 1.28 gpf Drake or dual-flush Aquia is usually favorable, but the fixture spec still needs to be in the permit packet. We handle that documentation as part of the job. Call (855) 901-7266 and we’ll tell you exactly what your remodel will require.
On Lompico well water, that’s almost always mineral scaling on the G-Max fill valve and flapper. The fill valve can’t close fully, so water trickles continuously, and the flapper doesn’t seat, so the flush is weak. We replace both with genuine Toto OEM parts, clean the rim jets, and the toilet flushes like it did when it was new. It’s a quick same-day Toto repair in Felton and Lompico for us.
Your cabin’s pier-and-post floor is flexing seasonally. Skirted one-piece models like the Ultramax II don’t tolerate movement the way a two-piece on a standard flange does. The fix is to shim the base, strap the flange to the subfloor, and set a new wax ring, but you have to address the movement or it’ll come back. We’ve done this enough times in Lompico — and for customers needing Toto in Mount Hermon — to know exactly where to shim and how much flex the setup can take.
Yes, and it’s one of our standard jobs. Most Lompico cabins from the 1950s through 1970s have tub surrounds we convert to walk-in showers using Toto valves and trim paired with Schluter waterproofing beneath the tile. The plumbing chase in older redwood cabins is often tight, so we may need to open a small section of wall to move the valve height. That’s normal for the housing stock here. Call (855) 901-7266 for a free estimate on the conversion.
