Kohler Construction in Sunnyvale, CA | Ashford Contractors
We provide independent Kohler construction service across Sunnyvale, from full bathroom remodels to cast-iron sink replacements and shower valve rebuilds, as your trusted Sunnyvale General Contractor. What makes our Kohler work different here is simple: we know Sunnyvale’s 1950s-60s slab-on-grade ranchers, and we know which Kohler rough-ins fit them without slab surgery. Call (877) 752-3868 for a free estimate on any Kohler installation, repair, or full remodel.
Why Sunnyvale Residents Choose Us for Kohler Service
Most contractors in Sunnyvale can set a toilet or hang a faucet. Fewer can walk into a 1960s rancher off Morse Avenue, open the wall, and tell you exactly what’s behind it: galvanized supply lines, shallow drain rough-ins, and a slab foundation with no crawlspace access. We’ve done this work across 94087, 94086, 94085, and 94089 long enough to know what a Kohler Memoirs rough-in demands before the demo starts.
Glen Mossier, owner at Ashford Contractors, trained in construction technology at Skyline College and has spent two decades learning what happens when a fixture and a foundation disagree. We use genuine Kohler OEM cartridges, flush valves, and trim where the finish or fit is proprietary, and quality aftermarket parts only on universal items like supply lines and wax rings. Independent means independent: we are not authorized, sponsored, or endorsed by Kohler, and we’ll tell you plainly which parts should stay genuine and which don’t matter.
One contractor. Every system. That’s the whole point of Kohler sales & service through Ashford: one project manager, one point of accountability, one crew that knows the fixture and the slab.

Common Kohler Construction Problems We Solve in Sunnyvale
- Cracked cast-iron apron-front sinks: Whitehaven and Dickinson sinks in older Sunnyvale ranchers crack at the drain or chip at the rim when heavy cookware drops. The enamel flaw hides under a cutting board until it leaks onto the cabinet base. On a slab-on-grade home, that leak travels across the floor before you even notice. We pull the sink, re-flash the counter opening, and set a new cast-iron unit on a fresh base.
- Scaled or stiff Simplice and Bellera faucet cartridges: Sunnyvale’s mineral-heavy supply hardens inside Kohler ceramic cartridges until the handle stiffens or drips. Replacing the OEM cartridge usually beats swapping the faucet, and we keep common cartridges on hand for faster turnaround.
- Weeping Memoirs and Devonshire flush valves: The flush valve seal degrades and the proprietary trip lever wears, producing phantom running water that shows up on the water bill instead of in the bowl. We replace the flush valve and lever with genuine Kohler parts rather than chasing the symptom.
- Pitted shower trim and valves: On Sunnyvale slab homes with shallow roof pitches and original single-pane glazing, condensation sits against shower tile and fittings. Trim finishes pit; valve bodies corrode. We rebuild or replace the valve and match the finish code so the new trim reads as original.
- Rough-in mismatches on slab foundations: Kohler fixtures sized for modern rough-ins often don’t reconcile with 1950s-60s plumbing set in a slab. We pre-plan the drain and supply routing before the slab is touched, which matters when Sunnyvale inspectors review plumbing rough-in alongside Title 24 and seismic calcs.
Kohler Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Here’s the thing about Kohler work in Sunnyvale that doesn’t apply a few miles away in Kohler in Santa Clara, Cupertino, or Milpitas: the city’s core housing stock sits on slab-on-grade foundations with no basement access, and a Kohler cast-iron sink or bath fixture sets into plumbing sized for galvanized supply and shallow drains. Any Kohler upgrade in these homes has to reconcile the fixture’s rough-in with a slab that won’t give you a second chance after the concrete is patched. Inspectors here review the Title 24 and seismic calcs right alongside the plumbing rough-in, so a bathroom remodel isn’t just a fixture swap; it’s a structural and energy-code exercise.
We recently handled a Memoirs toilet and Simplice faucet swap in a 1960s rancher off Morse Avenue in 94087, where the original single-pane glazing had let condensation eat into the shower trim and the cast-iron Whitehaven sink was chipped at the rim. We pulled the cracked sink, re-flashed the counter opening, and set a new Kohler cast-iron sink on a fresh base, then replaced the dripping Simplice cartridge with an OEM part. We scheduled the wet work around the late-fall rain window because the roof pitch there is shallow and the dry-in had to happen before the rains hit. Build it right the first time, and you won’t be rebuilding it in ten years.
Kohler Models & Products We Service in Sunnyvale
Our crews work across the Kohler lines that show up most in Sunnyvale homes: Memoirs and Devonshire bath collections (toilets, sinks, shower valves), Cast Iron kitchen sinks including the Whitehaven and Dickinson apron-fronts, Simplice and Bellera pull-down kitchen faucets, and Choreograph and Sterling shower wall systems. On OEM-vs-aftermarket, our stance is simple: genuine Kohler cartridges, flush valves, and trim where the fit or finish is proprietary, quality aftermarket on universal items only. For faster Sunnyvale turnaround, we stock common Kohler cartridges, flush seals, and trip levers, so a Tuesday call doesn’t mean a Friday repair.
This Kohler depth sits inside a much bigger scope. We’re a full-service general contractor, so when the shower valve turns into a wall rebuild or the sink replacement turns into a cabinet re-level on a slab floor, the same crew handles it. Full bathroom remodeling, walk-in shower installation, full kitchen remodeling; that’s the work we do in Sunnyvale service area homes week after week.

FAQs – Kohler Construction in Sunnyvale
Yes, but the slab changes the approach. The drain rough-in on a 1960s ranch was sized for the original fixture, so we verify the offset and floor flange before setting a Memoirs toilet. If the flange is rotted or the drain needs a slight offset, we handle the concrete work in the same visit rather than setting a toilet on a weak base. Call (877) 752-3868 to have us check your specific rough-in.
Repair. A stiff handle and a drip on a Simplice almost always point to a scaled ceramic cartridge, and an OEM cartridge replacement restores the faucet for a small fraction of replacement cost. Replace the faucet only if the body or finish has failed. Call (877) 752-3868 and we’ll diagnose it on site.
If the rim is intact and the enamel isn’t chipped, yes. A cast-iron Whitehaven or Dickinson holds up and looks right in a Sunnyvale ranch. If it’s chipped at the rim or cracked at the drain, we advise replacing it rather than chasing an enamel repair that won’t hold. In a slab home, the replacement also means re-flashing the counter opening, which we handle as part of the remodel.
Any bathroom remodel that touches the plumbing or walls triggers Sunnyvale’s permit review, and inspectors check Title 24 energy calcs and seismic details alongside the plumbing rough-in. That means the work gets done with the slab and the energy code in mind, not just the fixture swap. We pull the permits and schedule the inspections as part of the project.
Yes, always on proprietary items like flush valves, cartridges, and finish-matched trim. We use aftermarket only on universal parts like supply lines and wax rings, where it doesn’t affect fit or finish. If a Kohler toilet tank or cast-iron sink has cracked, we advise replacing the fixture instead of chasing a patch. Call (877) 752-3868 for a free estimate on your specific fixture.
