Toto Construction in Upland, CA | Polaris Contractors
We’re Polaris Contractors, an independent Toto service provider working across Upland, and we handle everything from Washlet bidet seat repairs to full Toto bathroom remodels. The one thing that separates our Toto work here from anyone else’s is that we check the flange and subfloor level on every installation, because Upland’s foothill soil moves. Call us at (855) 473-6535 for a free estimate, and we’ll bring nearly three decades of hands-on remodeling experience to your door.
Why Upland Residents Choose Us for Toto Service
Most plumbing suppliers in Upland can sell you a Toto toilet. Few can tell you why a Washlet nozzle is clogging with mineral scale, whether that cracked flange means the subfloor is shifting, or when an aftermarket fill valve will do the job as well as OEM. That’s the distinction. Rick Sondermann founded Polaris Contractors after years of building and renovating homes along the California coast, and that experience taught him something simple: fixture brands like Toto are only as good as the surface they’re mounted to and the water running through them. In Upland, both of those variables get complicated fast.
We stock the common Toto repair parts locally, which means less waiting when your toilet starts running or your bidet seat quits mid-cycle. And because we’re a full-scope general contractor, not a single-trade shop, we can handle the subfloor repair, the drywall patch, the outlet addition, and the tile work in the same visit. One team, full scope. That’s how we keep Upland Toto owners from juggling three phone numbers for one bathroom problem.

Common Toto Construction Problems We Solve in Upland
- Washlet nozzle clogging and low spray pressure. Upland’s water carries enough mineral content that Toto Washlet spray nozzles, especially on the S550e and K300 models, build scale faster than coastal homes see. We descale the internals with the right solution, replace clogged nozzle tips where needed, and check the inline filter. In most cases, the seat doesn’t need replacing, just proper cleaning and periodic maintenance.
- Silent tank leaks from degraded bolts and gaskets. Upland’s hot, dry summers and cold winter nights create wide swings in attic and crawlspace temperatures. Those swings age rubber tank bolts, gaskets, and supply line washers faster than expected. We see this most often in the pre-1970 housing stock near downtown, where crawlspaces bake all summer. A silent leak can add $40 to a monthly water bill before you notice anything.
- Electronic control board failures on Washlet seats. Older homes in downtown Upland frequently have ungrounded wiring, and power surges during Santa Ana wind events can spike electronics. Toto Washlet control boards, sensor arrays, and seat heating elements take the hit. We diagnose the board first, price the OEM replacement honestly, and tell you when a new unit is the better investment.
- Finish pitting on Toto faucets and accessories. The dry inland air and temperature swings in Upland’s foothill homes accelerate micro-abrasion on brushed nickel and oil-rubbed bronze finishes. Toto faucets and trims start to pit or flake on fixtures that would look new for another decade in a coastal home. We see this constantly on homes above Base Line Road.
- Cracked toilet flanges from soil movement in the 91784 ZIP. This one is Upland-specific. Expansive soils on the foothill side shrink during dry seasons and swell after winter rains. The pad shifts a fraction of an inch, the toilet flange cracks or tilts, and the wax seal fails. We inspect the flange and subfloor level on every Toto toilet installation in Upland because ignoring it means the new toilet starts leaking within a season or two.
Toto Service in Upland: What Local Conditions Mean for Your Equipment
If you live in the northern part of Upland, in the 91784 foothill ZIP, your home sits on graded pads cut into the San Gabriel Mountain foothills. Santa Ana winds funnel down those slopes every fall, and the expansive soils shrink during the hot, dry inland summers. What that means for your Toto fixtures is specific and checkable: minor foundation shifts are normal here, and they crack toilet flanges and misalign bidet seat mounts. Flat-valley builders rarely check for this. We do. On every Toto installation we perform in the foothill neighborhoods above Base Line Road, we inspect the flange, check the subfloor level, and make sure the fixture mounts are shimmed level before we tighten anything down. It’s a one-step check that prevents most recurrent toilet leaks in this ZIP code.
We recently remodeled a master bath in a 1980s foothill home off Base Line Road in the 91784 ZIP. The homeowner had a Toto Ultramax toilet with a cracked flange due to soil movement. We replaced the flange, reset the toilet with a new wax seal, and installed a Toto Washlet S550e with a GFCI outlet. We also converted the old tub to a walk-in shower with frameless glass, using Toto’s EcoPower sensor faucet for a modern touch. That job had three separate Toto components, one shifting subfloor, and one accountable team. That’s the ideal ratio.
Toto Models & Products We Service in Upland
We work on the full range of Toto products Upland homeowners actually live with: the Washlet bidet seat line including the S550e, C200, and K300; the Drake and Eco Drake toilet lines; the Ultramax and Ultramax II; and the Aquia and Neorest series for higher-end remodels. For critical components, fill valves, flush valves, and electronic boards, we specify OEM Toto parts because compatibility matters and warranty support is cleaner. For non-critical items like supply lines, seat bumpers, and cosmetic trims, we’ll use high-quality aftermarket parts when it saves you money without cutting corners. If a Washlet is over 10 years old and needs a control board that costs close to half a new seat, we’ll tell you that too. Rick’s approach has always been: do it right the first time, the second time always costs more.
Our Toto sales & service work starts with an honest diagnosis, not a replacement quote. That’s the foundation we bring to every call.

FAQs – Toto Construction in Upland
It depends on the seat’s age and the specific failure. Clogged nozzles from mineral scale are almost always repairable, and that’s the most common issue we see in Upland. A failed control board on a seat that’s over 10 years old is usually a replace situation, since the board cost can exceed half a new seat. Call (855) 473-6535 and we’ll diagnose it honestly, repair-first.
Yes, but it may require supply line updates. Many pre-1950 homes near downtown Upland have 1/2-inch galvanized supply lines that restrict flow to the Neorest’s integrated washlet system. We’ll check your supply pressure and line diameter, update what’s needed, and install the Neorest to Toto’s specification with the electrical requirement handled properly.
For Upland’s foothill homes, where water pressure can fluctuate across elevation, we recommend Toto’s pressure-balancing shower valves paired with a high-efficiency showerhead. Avoid rain-style heads that need high consistent pressure unless you’re adding a pressure booster. We’ll guide you to the right material for your specific water pressure, not just the most expensive option.
We replace them. A cracked Toto tank can’t be safely repaired, and the ceramic failure usually indicates either a thermal shock event or a manufacturing stress point. We’ll spec the replacement model to match your existing bowl where possible, which often saves money. Call (855) 473-6535 if you see a hairline crack, before it lets go under pressure.
Santa Ana winds drive dust and dry air into outdoor kitchens and enclosed patios, which accelerates finish wear on Toto faucets and can clog aerators faster than indoor fixtures. For outdoor or semi-outdoor Toto installations in Upland, we recommend sealed finishes and routine aerator cleaning every few months during the wind season. Call (855) 473-6535 for an exact quote on your setup, estimates are free.
