Drain cleaning is the fix when a sink, tub or shower drains slowly, or when a clog keeps coming back. We clear clogged drains and main sewer lines for homes across Marin and Sonoma County, from a single backed-up shower drain to a sewer backup.

We look for the cause first. Depending on the line, that may mean snaking, hydro jetting, root removal or a camera inspection to see inside the pipe. Grease, roots and aging clay pipe are common reasons drains fail, and the right method depends on what we find. We would rather clear the line and keep your pipes working than talk you into replacing them. If you suspect hidden water loss, our leak detection service can help, and our plumbing services page covers the rest.

We serve Marin County from our San Rafael office and Sonoma County from Santa Rosa and Petaluma, including Novato, Larkspur, Sebastopol and Petaluma. If sewage is backing up into a tub or floor drain, stop using the plumbing and call us.

We find out why the drain is blocked, use a camera when it helps, and explain your options before talking about replacement.

How a failing drain shows itself

  • More than one drain in the house is slow
  • Water comes up in a tub, shower or floor drain

  • The same clog returns after plunging or snaking
  • A sewer smell inside the house or in the yard
  • A soggy or unusually green patch in the yard

Frequently Asked Questions

How much does drain cleaning cost?

The cost depends on which line is blocked, how it is cleared and what we find inside. A single sink is different from a main sewer line. Call us, describe the problem, and we will explain the options for your drain.

Why is my shower drain clogged, and how do I unclog it?

Hair and soap buildup is a common cause. Plunging or snaking can clear a simple clog. If it returns, or other drains are slow too, the blockage may be deeper in the line, and it is worth having a plumber look at it.

What should I do about a sewer backup?

If sewage is backing up into a tub, shower or floor drain, stop using the plumbing and keep people away from the area. Then call a licensed plumber. A main line blockage can cause serious water damage if it is left.

Do you offer drain cleaning in Marin County and Sonoma County?

Yes. Marin homes are served from our San Rafael office, and Sonoma County homes from our Santa Rosa and Petaluma offices. That includes towns such as Novato, Larkspur, Sebastopol and Petaluma. We explain what we find in plain terms, so you can decide what to do next.

Why do my drains keep backing up?

Repeated backups usually mean something deeper than a simple clog, such as grease buildup, tree roots or a damaged pipe. We use a camera inspection when needed to find the cause, so the problem gets fixed rather than cleared once.
