Repair
Best for a solid toilet with worn internal parts.
- Flappers, fill and flush valves on the truck
- Wax seals, supply lines and closet bolts
- Most fixed on the first visit
From a toilet that runs all night to a clean, efficient new install, our licensed plumbers show up with common parts on the truck and get it right the first time, across Sonoma County, with a fixed price you approve before we start.
Pick the closest match. Each one tells you what it usually means and what to do next.
Usually a worn flapper or fill valve. An inexpensive fix, and a big water-saver once it's done.

Reviews
“I have worked with Simeone for years now, and they are amazing. Their plumbers, their office, and their ownership have been nothing but responsive and helpful and always make us a priority. Wouldn't use anyone else!!!”
“… With flooding in the area it got even harder. Gena was a great communicator, working with me to reschedule a couple of times and Domenic actually arrived a little early and got the work done quickly and professionally. Definitely a great company to work with.”
“I wish I could give this company 10 stars! This was my second time using Simeone and they are consistently professional and courteous from start to finish. …”
Why toilets run in Sonoma County
Minerals in local water keep flappers and fill valves from sealing properly, so the toilet runs. In homes where water pressure is above the 80 psi California code allows, fill valves wear out even faster.
Everything we do
A running toilet can waste hundreds of gallons a day. We fix flappers, fill and flush valves, wax seals, supply lines and loose closet bolts, and carry the common parts on the truck, so most repairs are done on the first visit.
Time for a new toilet? We install efficient, great-flushing models, from standard and comfort-height to dual-flush and one-piece, set level and sealed leak-free, plus bidet seats and commercial flushometer units.

Yes. We set and seal your model leak-free, and check it's complete before we start. We can't warranty the fixture itself, but our workmanship is backed by our Make‑It‑Right Guarantee.
Yes. A rocking toilet breaks its wax seal and can leak onto the subfloor. We re-set it level on a fresh seal so it stays put.
Repair makes sense when the toilet is solid and only the internal parts are worn. Replacement makes sense for an old, cracked or constantly clogging toilet. Your tech gives you the honest call and a fixed price for each.
It could be a low-flow model struggling, a venting issue, or a problem further down the line. If other drains are slow too, the main line may need drain cleaning or a camera inspection.
Start with a flange plunger made for toilets. Seal the cup over the drain, push gently at first, then use steady plunges. Skip chemical drain cleaners, wire hangers and aggressive force, which can damage seals, porcelain and older pipes.
Yes. We install and connect bidet seats, including heated seats with washes and dryers, sealed leak-free at the supply.
No. Diagnostics start at $99, and you get a fixed price approved before any work begins, so there are no surprises when the job's done.
