Kohler Construction in Montclair, CA | Polaris Contractors
We’re an independent contractor that handles our Home Remodeling in Montclair, from full bathroom remodels to tub-to-shower conversions and walk-in shower installations. We’re not authorized, sponsored, or endorsed by Kohler, and we’ll tell you that plainly. What makes our Kohler work different in Montclair is that we plan for this city’s tightly packed post-war lots, where a cast-iron tub often has to be hand-carried through a narrow side yard instead of brought around the back. Call (855) 473-6535 for a free estimate on your Kohler project.
Why Montclair Residents Choose Us for Kohler Service
Rick Sondermann, our owner, has spent the better part of three decades building and renovating homes, and he’s installed enough Kohler fixtures to know which models hold up and which ones don’t on Montclair’s mineral-heavy water. We’re not just a plumbing crew that happens to touch Kohler. We’re a full-scope Montclair General Contractor that manages the entire bathroom or kitchen project, from subfloor to shower valve, so the Kohler fixture and the framing behind it work as one system. When you hire us, you get one team accountable for the whole job, not a patchwork of subs pointing fingers when a tub flexes or a valve seats badly.
We also carry genuine Kohler OEM fill valves, flush canisters, cartridges, and gaskets for anything still under a usable factory finish. That matters in a city where a running Wellworth toilet can waste hundreds of gallons a month. And because we’re local to Montclair, we’re not scheduling you three weeks out from another county. We know the streets, the housing stock, and the permitting office. Check our Montclair service area page for full coverage details.

Common Kohler Construction Problems We Solve in Montclair
- Wellworth and Highline toilets that run constantly or flush weak. Montclair’s water is hard and mineral-heavy, and the fill and flush valves on these two-piece toilets are often the first things to go. We swap in genuine Kohler OEM valves and set the tank for your home’s actual water pressure, which varies block to block in the older 1950s-60s tracts.
- Kohler Villager cast-iron tubs with cracked enamel near the drain. We see this a lot on original ranch homes where the subfloor was never beefed up. The floor flexes under the tub’s weight, and the enamel gives way at the drain opening. It’s not a cosmetic chip. It’s a structural problem, and we fix the floor before we touch the tub.
- Forté and Purist faucet cartridges that seize or drip. Years of hot inland summers and hard water deposits bind chrome-on-brass cartridges. If yours drips after you’ve replaced the cartridge once or twice, the valve body may be scored. We’ll tell you straight when a new faucet costs less than another repair.
- Memoirs toilet tank-to-bowl gaskets and bolts that seep. Older tract homes in Montclair have irregular shutoff pressure, and the Memoirs tank uses a narrow gasket channel. We re-torque to spec and use OEM gaskets so you don’t get a slow seep that rots the bathroom floor.
- Kohler Choreograph surround panels that were never installed on a flat wall. Montclair’s post-war framing is rarely square. If a previous contractor slapped panels over a bowed stud, they’ll crack or gap at the seams. We shim and true the walls before the surround goes in.
Kohler Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair’s flat, low-scale, tightly packed post-war lots on the west side near Holt Blvd are the defining challenge of every Kohler construction job we take here. Many of these homes have no rear-yard access at all. The garage sits at the back of the lot, the side yards are four or five feet wide, and there’s no way to bring a crane or a heavy delivery cart around the house. A Kohler Villager cast-iron tub weighs over 300 pounds. A double vanity in a Memoirs bathroom can weigh 200 pounds before the countertop goes on. In Claremont or Upland, where lots are larger and many homes have drive-through side access, a crew just wheels equipment to the back. In Montclair, we hand-carry every piece down a narrow side yard, through a back door, or sometimes through the front room and down a hallway. That means we plan staging, door width, floor protection, and crew timing differently from day one. If a contractor quotes you a Montclair tub conversion without asking how they’re getting the tub out, they haven’t thought about your house.
On a 1960s ranch off Holt Blvd on the west side, our crew pulled the original Kohler Villager during a tub-to-shower conversion and found the enamel cracked at the drain from a flexing subfloor. We reset the subfloor, fit a Kohler Choreograph shower surround and a Forté valve with OEM cartridge, hand-carrying every piece down the narrow side yard since the lot had no rear access. The homeowner got a walk-in shower that finally suits the house. That’s the kind of job you can’t plan from a distant office.
Kohler Models & Products We Service in Montclair
We service the Kohler lines most common in Montclair’s 1950s-1970s housing stock and the models most often specified in our remodels. That includes Wellworth and Highline two-piece toilets, Memoirs and Devonshire bath fixtures, Forté and Purist faucet lines, and Villager cast-iron tubs. On the parts side, our approach is simple: genuine Kohler OEM fill valves, flush canisters, cartridges, and gaskets whenever the fixture still has a usable factory finish. We only turn to quality aftermarket parts on discontinued lines where OEM stock has dried up. If you’ve got a cracked enamel tub or a failed valve body, we won’t sell you another patch job. We’ll tell you when repair stops paying and replacement makes more sense. For a broader look at the brand work we do, see our Kohler sales & service page.

AfterKohler Service Pricing in Montclair
What you’ll pay depends on your house, your fixture, and how far the project goes. A tub-to-shower conversion in Montclair runs higher than in cities with rear yard access, because hand-carrying a 300-pound cast-iron tub out of the house and a shower base and wall panels back in takes more labor. We give free estimates that include line-item pricing, so you see exactly where the hours go.
| Project | Typical Range |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Shower Replacement | $3,000 – $8,500 |
| Bathroom Vanity Installation | $800 – $3,000 |

FAQs – Kohler Construction in Montclair
Yes. A running tank is usually a worn fill or flush valve, and on Montclair’s mineral-heavy water, those valves wear out faster than KohlOHLER’s average lifespan numbers suggest. We replace the valve with a genuine Kohler OEM part, set the tank to your home’s actual water pressure, and the leak stops. Call (855) 473-6535 and we’ll get you a quote.
If the enamel crack came from a flexing subfloor, as we see on many 1950s-60s Montclair ranches, repair is a holding action, not a fix. We’d reset the subfloor before installing a new tub or converting to a walk-in shower. If the crack is cosmetic and the floor is solid, repair may buy you years. We’ll give you an honest answer after we look at the framing. Call (855) 473-6535 to schedule a free estimate.
No. We handle no-rear-access lots every week on the west side near Holt Blvd. We hand-carry tubs and vanities down narrow side yards and through the house, which means we plan door widths, floor protection, and crew timing accordingly. It takes more labor, but it’s not a problem.
Hard water and hot inland summers are hard on Forté cartridges. Mineral deposits score the brass valve seats, and eventually the cartridge can’t seal even when it’s new. We’ll replace the cartridge with OEM, and if the valve body is scored beyond repair, we’ll tell you honestly that a new faucet is the smarter spend.
No. Polaris Contractors is an independent contractor. We are not authorized, sponsored, or endorsed by Kohler. We use genuine Kohler OEM parts where they’re best for your fixture, but we answer to you, not to the manufacturer.
