Kohler Construction in Los Altos, CA | Seaside Contractors
We install and service Kohler fixtures throughout Los Altos, from unclogging a seized Bellwether tub drain on a 1950s ranch to roughing in a new Purist shower system on a full gut remodel handled by our General Contractor in Los Altos. The work here is different because nearly every job sits on a mature lot with heritage oaks and a crawlspace or shallow slab that hasn’t been touched in sixty years. So we plan around the tree before we plan the plumbing. If you’re in Los Altos, call (833) 589-8103 and we’ll take a look.
Seaside Contractors is a full-scope general contractor that handles Kohler sales & service as part of every bathroom, kitchen, and whole-home project. That matters in Los Altos, where a “simple” tub swap usually turns into subfloor repair, re-routing a drain around a protected root zone, and a building permit. Having one crew manage all of it keeps the job moving.
Why Los Altos Residents Choose Us for Kohler Service
Most of the homes we work in across Los Altos service area were built before Kohler moved to cartridge-based faucets. We still see original Villager and Bellwether cast-iron tubs, Memoirs toilets with failing fill valves, and Purist faucets that have calcified from decades of Peninsula water. Our crew works on those fixtures every week, which means we don’t have to guess at the rough-in dimensions or order the wrong trim.
Glen Sorrento, our owner, grew up in Foster City watching lagoon-side homes get built and rebuilt, then studied building construction technology at College of San Mateo before spending two decades running jobs across the Peninsula. That background means he can look at a 1962 Los Altos ranch bathroom and tell you whether the Kohler cast iron is worth saving or whether a walk-in shower conversion is the smarter spend—skills he’s also applied on Kohler repair in Stanford. His line is: “Let’s figure out what the job actually needs, then we’ll talk materials.”
We’re an independent contractor, not a Kohler authorized dealer. That independence lets us recommend repair when a fixture still has life in it, and replacement when it doesn’t. We source genuine Kohler OEM cartridges, fill valves, and trim wherever they’re in production, and use quality aftermarket equivalents when a part is discontinued.

Common Kohler Construction Problems We Solve in Los Altos
These are the specific failures we see repeatedly in Los Altos homes, and each one connects to the local housing stock or climate:
- Enamel-worn cast-iron tubs with seized drain assemblies. Original 1950s – 60s ranch bathrooms in Los Altos often have a Kohler Bellwether or Villager tub with enamel worn through to bare iron and an overflow assembly so corroded it won’t budge. We usually recommend a tub-to-shower conversion rather than fighting the old rough-in.
- Ceramic-cartridge faucets that drip or stiffen. Kohler Purist and Artifacts kitchen and lav faucets are prone to scale buildup in the cartridge from the Peninsula’s harder water. In Los Altos, we see cartridges that won’t turn off fully or handles that grind against mineral deposits. Most fix with a genuine Kohler replacement cartridge.
- Memoirs and Farmington toilets with phantom running or hairline tank cracks. The original vitreous china in older Los Altos homes develops micro-cracks at the tank-to-bowl joint, or the flapper and fill valve fail and the toilet cycles all night. Sometimes it’s a $40 fill valve; sometimes the china is cracked and it’s time to rough in a new Memoirs Stately.
- Hidden subfloor rot under a leaking tub overflow. Los Altos homes on shallow crawlspaces or concrete slabs are especially vulnerable. A Kohler cast-iron tub whose overflow leaked for years may have rotted the subfloor or joists beneath it. We find this when we open the floor for a walk-in shower install.
- Rough-in dimensions that don’t match modern Kohler fixtures. Older Los Altos bedrooms and baths weren’t framed for today’s Kohler Memoirs vanities or WaterHaven-style shower systems. We handle the reframing, drain relocation, and slab work so the new Kohler fixture fits without compromise.
Kohler Service in Los Altos: What Local Conditions Mean for Your Equipment
On many Los Altos lots a heritage coast live oak inside the drip line triggers city tree-protection review and root-zone fencing. That can dictate foundation setbacks and pier placement, which means on a Kohler bath or kitchen remodel we often have to route drain and supply lines around protected root zones before we ever set a tub or vanity. It’s a Los Altos-specific constraint that doesn’t apply the same way in Mountain View or Palo Alto, where the lots are tighter and the trees are younger.
We saw this on a ranch-home gut remodel off a mature-oak lot in Los Altos. The homeowners wanted a walk-in shower where their original Kohler Villager cast-iron tub sat for decades. The tub’s overflow had been seeping into a shallow crawlspace for years, and the oak drip line limited where we could cut the slab. We re-routed the drain around the root zone, set the Kohler shower valve and trim before framing the enclosure, and delivered a code-clean conversion instead of a tub that kept leaking. That’s the kind of sequencing you can’t plan from a product spec sheet.
Kohler Models & Products We Service in Los Altos
We install and repair the full Kohler range that shows up in Los Altos homes: Memoirs and Memoirs Stately toilets and vanities, Bellwether and Villager cast-iron alcove tubs, Purist and Artifacts faucet and shower trim, and Caxton and Farmington under-mount bathroom sinks. For older fixtures, we source genuine Kohler OEM cartridges, fill valves, flappers, and trim when they’re still in production. When a Kohler part is discontinued or on long lead time, we’ll tell you straight and offer a quality aftermarket equivalent that matches the original spec.
On cast-iron and vitreous china fixtures we lean toward repair when the body is sound and the rough-in still matches. We recommend replacement when the enamel is through, the china is cracked, or the drainage is too far gone to save. It’s not about pushing a sale. It’s about not putting new trim on a tub that’s going to fail again next year.

FAQs – Kohler Construction in Los Altos
Yes. We do tub-to-shower conversions and walk-in shower installations in Los Altos ranch homes routinely, including pulling original Kohler Bellwether or Villager tubs, repairing the subfloor if the overflow leaked, re-routing the drain if a heritage oak limits slab cuts, and setting the new Kohler valve and shower pan. Call (833) 589-8103 and we’ll walk your specific bathroom before we quote it.
Most Purist drips are the ceramic cartridge, which we can replace with a genuine Kohler OEM cartridge for significantly less than a full faucet. If the body is solid, repair is the right call. If the finish is degrading or the spout has internal wear, replacement may be smarter. Either way, call (833) 589-8103 and we’ll give you an honest read.
We do. Memoirs and Memoirs Stately pieces are a common fit for the 1950s – 60s Los Altos ranch aesthetic, and we handle the rough-in work: moving supply lines, adjusting drain centers, and shimming vanities on floors that have settled. The old galvanized plumbing in these homes often needs attention before the new fixture goes in, and we’re set up for that.
It can. On Los Altos lots where a heritage coast live oak sits inside the drip line of the work area, the city may require tree-protection review and root-zone fencing. If your Kohler bath or kitchen remodel means cutting slab or routing new drains near those roots, we design around the tree before we design the fixture placement. It’s part of getting the permit clean.
No. Seaside Contractors is an independent contractor. We are not authorized, sponsored, or endorsed by Kohler. That independence means we can tell you plainly when a Kohler fixture is worth repairing and when you’d be better served by replacing it.
