Toto Construction in Montclair, CA | Pinecrest Contractors
We provide independent Toto service and installation across Montclair’s 91763 homes, from full bathroom remodels with walk-in showers to tub-to-shower conversions and Washlet installs. The one thing that makes our Toto work different here: we understand how Montclair’s post-war slabs, aging galvanized supply lines, and hard Pomona Valley water affect Toto fixtures. Call (855) 702-1622 for a free estimate on your Toto project.

Why Montclair Residents Choose Us for Toto Service
We’ve pulled and reset hundreds of Toto fixtures in Montclair’s 1950s and 1960s tract homes, and we know how these toilets behave on original post-war slabs and aging plumbing. Not from a spec sheet. From doing the work. Gil Rourke, our owner, learned construction at Palomar College and spent years working every phase of residential builds before founding Pinecrest Contractors. He still keeps a worn framing square from his framing days hanging in his truck cab. That experience shows up in how we diagnose a weak-flushing Drake or a rocking Ultramax. We stock genuine Toto OEM fill valves, flappers, and gaskets so we can fix most Montclair Toto issues without waiting on a parts order. And because we’re local to the Pomona Valley, we can usually get to your project quickly and assess it correctly the first time. We also provide Toto service in Upland for clients just east of Montclair.

Common Toto Construction Problems We Solve in Montclair
- Weak or phantom flushes on original-build Drakes and Eco Drakes. These toilets are now 20 to 35 years old in Montclair homes, and the fill valves and flappers fail first. We replace them with genuine Toto internals, not aftermarket parts that tend to fail early.
- Flush pressure problems caused by corroded galvanized supply lines. Montclair’s original steel supply runs narrow over time from internal corrosion. A high-efficiency Toto needs consistent pressure to flush correctly, so we check the shutoff and supply before assuming the fixture is the problem.
- Washlet scaling and weak spray. The Pomona Valley’s hard mineral water builds up on Washlet inlet filters and nozzles fast, especially on homes with older steel supply lines. We clean or replace the filters and descale the nozzles so the seat works like it should.
- Wax-ring leaks after a homeowner swaps a toilet. We find original Toto fixtures set on slightly off-level 1950s slabs all over Montclair. If the flange wasn’t corrected, a simple bowl swap turns into a slow leak at the base. We reset flanges and level the fixture properly.
- Cracked ceramics or seat-mount failures on older Toto bowls. When the trap or seat mount is cracked, repair isn’t worth it. We’ll tell you honestly and quote a replacement only when the fixture is beyond saving.
Toto Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair is essentially built out. The 91763 lot stock was largely platted in the post-war boom and is now infill, which means nearly every Toto bathroom or kitchen job here is a remodel inside an existing 1950s to 1970s footprint on the original slab. Fixture swaps routinely collide with old drain stubs and framing that a new-build job would never surface. On a bathroom remodel off a narrow post-war lot near the Montclair side of the 91763 grid, we pulled an original Toto Drake that was flushing weakly, found a scaled fill valve and a supply line choked with galvanized corrosion, and reset a new Eco Drake on a corrected flange while we were already gutting for a walk-in shower. The customer kept the old Drake bowl as a spare because the ceramic was still sound. That’s the kind of thing you only learn by working inside Montclair’s existing housing stock, not by reading a product brochure. The right material in the right place, that’s where the job starts.
Toto Models & Products We Service in Montclair
We work on the full Toto lineup: the original round-front and elongated two-piece Drake, the high-efficiency Eco Drake, the one-piece Ultramax, and the Washlet bidet seats and Neorest integrated toilets. Our parts approach is simple. For the fill-and-flush internals, we use genuine Toto OEM components because aftermarket parts on a Drake or Ultramax tend to fail early and cause repeat calls. We keep common OEM fill valves, flappers, and gaskets stocked locally so most Montclair repairs don’t wait on a shipped order. When a Toto is still structurally sound, we rebuild it rather than push a replacement. A full reset or flush-valve rebuild is usually the better call on a solid original fixture. Replacement only comes up when the ceramic trap or seat mount is cracked, which we’ll show you before quoting anything.

FAQs – Toto Construction in Montclair
Usually not. Weak flushes on a 20 to 35 year old Drake are almost always a failed fill valve, a worn flapper, or a supply line narrowed by galvanized corrosion. We rebuild the internals with genuine Toto OEM parts and check the supply pressure before recommending replacement. Call (855) 702-1622 if you want us to diagnose yours.
In most cases, yes. A Washlet seat can be added to an existing Toto bowl using the current water supply, as long as the shutoff and supply line are in good shape. We check the supply condition because older galvanized runs in 91763 homes can restrict flow and cause weak spray. Call (855) 702-1622 for a free Washlet install assessment.
It’s usually the flange. Original 1950s slabs in Montclair are often slightly off-level, and if a remodel didn’t reset the flange to match the new finish floor height, the bowl will rock and the wax ring will eventually fail. We level the bowl, correct the flange if needed, and use a jumbo wax or neoprene seal. Call (855) 702-1622 and we’ll take a look.
Yes, and we do it often. Montclair’s post-war bungalows have compact bathrooms, so a tub-to-shower conversion with a Toto toilet reset and a wall-hung vanity opens up floor space without moving walls. Most of these conversions run $3,500 to $10,000 depending on finish choices. Call (855) 702-1622 for an exact quote.
No. We’re an independent contractor, not a Toto factory-authorized shop. That’s intentional. We aren’t bound to manufacturer pricing or a sales quota, so we’ll repair a serviceable Toto rather than push a replacement, and we’ll tell you when aftermarket parts are fine and when they’re a waste of money. Call (855) 702-1622 to talk through your project.
