Tiburon plumber for leaky toilets, clogged toilets and pipe leaks. We find the cause and explain the repair first.
A toilet that leaks, a pipe that weeps, a tub that will not drain: these are the problems Tiburon homeowners bring to our plumbers. Water damage builds quietly, so catching a leak early usually costs less. We find where the water is coming from, explain what is going on, and lay out the choices before we do any work.
We serve Tiburon from our San Rafael office, and John Owens Services has worked in Marin since 1986. If you suspect a hidden leak, our leak detection service looks inside walls and under floors. A clogged toilet or a slow line may call for drain and sewer cleaning.
We repair first. When a toilet or pipe is beyond saving, we recommend a replacement and give a free estimate. Our rule is maintain first, repair when needed, replace last. For hot water, see our water heater page. Financing is available, and seniors and veterans save $50 off any repair. Free estimates cover replacements and installations.
We tell you the cause, the fix and your options in plain terms, so there are no surprises mid-job.
A leak at the base can come from a worn seal or a loose connection. Water on the floor can also damage the subfloor if it goes unnoticed. We check the toilet, repair the seal or connection, and tell you if a replacement makes more sense.
Yes. Our leak detection service helps locate hidden leaks. Signs include unexplained water usage, stains, damp areas or musty odors. We find the source first, so the repair is aimed at the actual problem and not a guess. Then we explain the options.
Repeated clogging often points to a larger blockage somewhere in the drain line. We can inspect the line, clear the blockage, and explain what we found, so you know whether the problem is likely to return and what to do about it.
Repiping may be worth considering if you have frequent leaks, rusty water or low pressure. We inspect the system first. If repairs will do, we say so. If repiping is the better path, we explain why and give you a free estimate.
Permit needs depend on the work involved. John Owens Services handles the permit process for you before work begins. Tell us about your project, and we will explain what the job involves, what we recommend, and what a free estimate would cover.
Yes, call us right away for a burst pipe, a major leak, no water or a sewage backup. Shut off the main water valve first if you can. Our San Rafael office answers Monday through Friday, 7:30 AM to 5:30 PM, and fits urgent calls in the same day whenever the schedule allows. We will tell you honestly when a plumber can get there.
