Drain cleaning in Thousand Oaks

5.0 on Google (20 reviews) CSLB Lic. #339618 Family shop since 1977

Drain cleaning in Thousand Oaks, ten minutes from the shop in Westlake Village. A slow drain is a small job and a backed-up main is an urgent one. We can often clear either one the same day.

Dan picks up when he can and calls back the same day. You get the price before we start. Monday to Friday, 9am – 5pm.

Around here

In Thousand Oaks

Thousand Oaks protects its oaks by ordinance, and that matters for drain cleaning when a clog turns out to be in the sewer. The shortest trench can run through a root zone you can't dig in. So we clear the line and camera it if it's backed up before. In November 2025 one main here was blocked with flushable wipes and another with roots.

Neighborhoods: Lang Ranch, Sunset Hills, North Ranch, the Westlake side of the boulevard, the older tracts off Erbes Road, central Thousand Oaks, Newbury Park.

01

The drain backs up every few months

Sewer laterals & roots

We run a camera first so you can see which joint has gone. Then it's one section or the whole run, dug around whatever's growing over it.

The job

How it goes

We use a cable machine: a small one for sinks, tubs and showers, and a drum machine with a cutting head for the main. If there's a cleanout we run from there, so nothing goes through your toilet or across your floor.

Grease clogs kitchen lines and hair clogs tubs. Once it's clear we run water and watch it, since a half-cleared drain is back in a month.

Main lines are different. Roots get into old clay joints, cast iron scales up, and sagging sections hold water. If your main has backed up more than once in a year, we'll put a camera down it and show you what's there.

Call if

A new toilet in a guest bathroom

In central Thousand Oaks. We pulled the old toilet in the back guest bath and set a Toto Ultramax with a new wax seal, a new supply line, caulk at the base and a soft-close seat.

November 2025

A main line blocked with flushable wipes

Snaked the main from several points and pulled out a pile of wipes. Same month, another house: roots in the main, cut out with a chain knocker and checked with the camera.

Common questions

Drain cleaning in Thousand Oaks: things people ask

How fast can you get to Thousand Oaks?

Often the same day. The east side is ten minutes from the shop, and Newbury Park is the far end. Call and Dan will give you a time.

Does the oak tree ordinance affect a sewer repair?

It can. The city protects oaks and their root zones, so a trench can't always take the shortest route. We locate the line from the surface and plan around the trees first.

Should I try a chemical drain cleaner first?

No. It sits on the clog until someone opens the trap and gets it on their hands, and it eats older pipe. Try hot water and a plunger, then call.

Why does my main line keep backing up?

Clearing removes the clog and leaves the cause, like roots, a low spot or a crack that catches paper. A camera shows which.

Do you have to go through my toilet?

Not if there's a cleanout. We run the cable from there, and if you don't have one, we can add one.
