Toto Construction in Hillsborough, CA | Brookside Contractors
We install, repair, and retrofit Toto toilets and Washlet bidet seats throughout our Hillsborough service area, and the one thing that makes our Toto work here different is that we plan around the town’s design-review process and hillside conditions, not just the fixture itself. Brookside Contractors is an independent Toto service provider, not a manufacturer-authorized shop, which means we stock OEM parts, match existing finishes, and document your installation so design review doesn’t stall your remodel. Call (833) 725-3508 for a free estimate on any Toto project in Hillsborough.
Why Hillsborough Residents Choose Us for Toto Service
Nate Burrell, our owner and general contractor, grew up watching cheap crews walk off jobs and leave homeowners holding the repair bill. That’s why our approach to Toto work is the same as it is for a full foundation-to-finish remodel: do it once, do it right, everything else is just a future repair bill. We’ve installed, repaired, and retrofitted Toto fixtures in Hillsborough’s custom homes long enough to know that a toilet swap here is rarely just a toilet swap. It can involve a design-review check, a hillside floor that’s not quite level, or a cast-iron drain flange that’s been corroding since the house was built in 1962. When you call us, you get a crew that understands the fixture and the house it’s going into. We keep OEM Toto fill valves, flappers, and gaskets on hand, so most repairs don’t wait on factory orders.
We’re also a full-scope general contractor, which matters more in Hillsborough than most people expect. A leaking Toto flange can hide water damage in the subfloor. A vanity swap can open up a wall. One contractor, every phase, means you’re not coordinating a plumber, a tile setter, and a carpenter yourself.

Common Toto Construction Problems We Solve in Hillsborough
- Running toilets from hard, mineral-rich water. Hillsborough’s municipal water is hard enough that Toto fill valves and flappers wear out noticeably faster here than they do in softer-water towns. The minerals build up on the flapper seat, which breaks the seal, which means the toilet runs and your water bill climbs. We replace worn parts with OEM Toto components rather than generic aftermarket ones, because the aftermarket flappers rarely seat correctly on a Toto flush valve.
- Washlet bidet seat electronics failing after Peninsula power surges. Hillsborough’s wooded hillsides mean overhead power lines and winter storm outages. When power comes back, the surge can fry the control board in a Toto Washlet S550e or C200. We see this every storm season. The fix is usually a replacement control module, but the real lesson is to put a surge protector on the outlet that serves the bidet seat.
- Toilet flange corrosion on mid-century cast-iron drains. A lot of Hillsborough’s original estates still have cast-iron drain pipes under the bathroom floor. Over 50 or 60 years, the flange that the toilet bolts to rusts until it’s barely holding. When a Toto toilet rocks or a wax ring fails, the first thing we check is the flange, not the toilet. We replace them with stainless-steel repair rings that will outlast the rest of the plumbing.
- Skirted Toto models leaking at the tank-to-bowl gasket. Hillsborough homes on hillside lots frequently have bathroom floors with a slight slope, even when the rest of the house feels level. On a skirted model like the Toto Aquia IV, if the tank isn’t torqued evenly during installation, the gasket between tank and bowl compresses unevenly and weeps. It’s a slow leak, often mistaken for condensation, and it can warp the subfloor before anyone notices.
- Design-review conflicts with replacement fixtures. Hillsborough’s design-review process often requires bathroom remodels to match the original architectural style. We’ve watched homeowners buy a sleek new Toto and a floating vanity, then get sent back to the drawing board because the town wants the bathroom to read as consistent with the home’s mid-century character. We document the existing fixture footprint and finish details before we touch anything, so the replacement passes review the first time.
Toto Service in Hillsborough: What Local Conditions Mean for Your Equipment
Hillsborough’s design-review process is the part of this town that most outside contractors simply don’t plan for, and it has a direct impact on Toto work. The town requires bathroom remodels to stay consistent with the original architectural style of the home, and on a large-lot estate with protected heritage oaks and a specific hillside grading plan, that review can stall a simple toilet replacement for weeks if the paperwork doesn’t line up. We document the existing fixture footprint, finish details, and valve placement before we start, so when we replace a Toto Drake II or an Ultramax II, the new installation matches the original design intent and clears design review without a second round of revisions. On a full bathroom remodel in the Hillsborough Oaks area, our crew discovered the existing Toto Ultramax II was leaking at the flange due to a corroded cast-iron ring under the original tile floor. We replaced the flange with a stainless-steel repair ring, installed a new Toto Drake with an OEM waxless seal, and re-tiled the floor to match the home’s mid-century character, then provided documentation for the town’s design-review approval. That’s the kind of thing you only learn by doing Toto work in Hillsborough specifically.
Toto Models & Products We Service in Hillsborough
We work on the full Toto lineup, from the classic Drake and Drake II to the Aquia IV skirted dual-flush, the one-piece Ultramax II, and the Washlet bidet seat family including the S550e and C200. For repairs, we use OEM Toto parts exclusively: fill valves, flappers, tank-to-bowl gaskets, and Washlet control modules. Aftermarket parts void the warranty and rarely perform the same. For older Toto toilets where the bowl and tank are still sound, we generally recommend rebuilding with a Toto service kit rather than replacing the whole fixture. It’s cheaper, keeps the fixture out of the landfill, and preserves the original look that Hillsborough’s design review wants to see. Our full Toto sales and service work spans every model family, and because this is Hillsborough, we keep the most common parts on the truck so we aren’t chasing a factory order for a fill valve.

FAQs – Toto Construction in Hillsborough
No, a straight toilet replacement, where the footprint and finish match the existing fixture, typically does not trigger design review in Hillsborough. What does trigger review is a remodel that changes the layout, the wall finishes, or the architectural character of the bathroom. We document the existing fixture before we pull it, so if review does come up, you have the paperwork ready. Call (833) 725-3508 if you’re unsure whether your project needs review.
Yes, a Washlet bidet seat mounts to the toilet bowl, not the drain, so the cast-iron drain itself doesn’t prevent installation. The real concern is whether the existing toilet flange and wax ring are sound enough to handle the toilet that the Washlet sits on, plus the added weight and electrical work for the seat. We check the flange and the outlet while we’re there. Call (833) 725-3508 to schedule a look.
The best model for hard water is one with a simple, serviceable flush valve and a glazed trapway, and we typically steer Hillsborough customers toward the Toto Drake or Drake II for that reason. The minerals in Hillsborough’s water build up on flappers and fill valves over time, and Drake parts are the most straightforward to service with OEM components. The Aquia IV is a great toilet too, but the skirted design means more labor when the tank-to-bowl gasket eventually needs attention.
Hillside grading affects bathroom remodels in Hillsborough mainly through floor slope and drainage pitch. Homes on sloping lots often have bathroom floors that drop a fraction of an inch across the room, which means a toilet or vanity has to be shimmed and leveled correctly, and the wax ring or waxless seal needs to be chosen for the actual floor condition, not the spec sheet. We check floor level with a laser before setting any fixture. For an exact scope on your hillside bathroom, call (833) 725-3508.
Yes, we keep OEM fill valves, flappers, and gaskets for the Ultramax, Ultramax II, Drake, and Drake II on hand, along with the common Washlet control modules. For older models, we’ll usually recommend a rebuild with a Toto service kit if the bowl and tank are still sound. Parts availability in Hillsborough is one of the reasons homeowners call us instead of waiting on a big-box special order.
