Where the blockage sits tells you most of what you need to know. A single fixture backing up on its own means the problem is local, in the trap or the branch line serving it, and that is the quickest kind of job. Two or more fixtures backing up together means the obstruction is further down where their lines join, and if the lowest drain in the house is the one overflowing, the main line is involved.
The cause matters as much as the location. Hair and soap at a bathroom trap is a straightforward clear. Hardened fat in a kitchen line will come back unless the wall gets cleaned properly rather than bored through. Roots at a joint in the main are seasonal and will return on schedule. Foreign objects, which in family homes are more common than people admit, are one-time events.
We clear it, then tell you which of those it was. If it is a one-off you will hear exactly that. Book a free estimate any time, no obligation.
I had a backed up kitchen drain and David from Works Plumbing came out and cleared the line in a matter of minutes. Very professional and very knowledgeable. Definitely recommend!

Every drain clearing comes with upfront pricing, licensed and background-checked technicians, and a 100% satisfaction guarantee. Works Plumbing holds California contractor license #982663, carries full bonding and insurance, and holds an A+ rating with the Better Business Bureau.
We are a plumbing-only shop, which means the tech at your door has spent years on this exact work rather than splitting time across three trades. Our crews are drug tested as well as background checked, and dispatch is staffed by real people around the clock. No surprises, no commission-driven upsells, no pressure, ever.
Before you call anyone, check whether more than one fixture is affected. Run the sink, the tub, and flush the toilet, and note what happens. One slow fixture is a small local job. Several slowing together, or waste rising in the lowest drain, is a main line problem and a different conversation. Knowing which you have stops you paying for the wrong service.

Here are the questions we hear most. Don’t see yours? Give us a ring, a real human answers, day or night.
Often, yes, and we would rather you tried. A cup plunger on a sink or tub, with the overflow covered, clears a lot of shallow blockages. So does removing and cleaning the P-trap under a sink, which is where most bathroom clogs live, though put a bucket underneath first. What we would ask you not to do is pour chemical drain cleaner down it, for the reasons in the pro tip above.
Three reasons. It rarely clears a genuine blockage, because it needs contact time and the water sitting above the clog dilutes it. It sits in the trap corroding the pipe while it waits, which is a real problem in older metal drain lines. And it makes the line hazardous for whoever opens it next, which may well be you. Hot water and a plunger are safe. Beyond that, it needs a cable.
Same day in the great majority of cases, and we treat a fully blocked main or an overflowing toilet as an emergency. Dispatch is staffed 24/7 including weekends, our average on-site response for emergencies is under 60 minutes, and there are stocked trucks working out of all three locations, so someone is usually already nearby rather than crossing the county.
Then the first clearing treated the symptom and something structural is causing it, and we want to know. A repeat blockage in the same place means grease on the wall, a defect in the pipe, root intrusion, or a section that has sagged and holds water. That is when the camera goes in, and you see the footage. Clearing the same line four times a year is a worse deal for you than fixing the cause once.
Usually yes. We run stocked trucks out of all three of our locations in Pacifica, San Francisco, and Burlingame, so there is generally a van already working near you rather than one dispatched from across the county. Our average on-site response for emergencies is under 60 minutes, and dispatch is staffed 24/7 including weekends and holidays. A real person answers the phone, so you will know within minutes whether we can be there today.
Every job is backed by our 100% satisfaction guarantee. If the same problem returns, call us and we come back out to make it right. We test our work before leaving rather than packing up the moment it looks finished, which is the main reason callbacks are rare. Parts and equipment carry their manufacturer warranty on top of our own guarantee.
Three Peninsula locations put a stocked truck near you, from San Francisco down to Atherton, covering 22+ cities every day.
Combined across our Pacifica, San Francisco, and Burlingame locations.
