Your sewer Is usually out of sight and mind – Until it blocks!

Sewage systems play an important role in buildings and homes. It is how all your waste water including toilet water leaves your home and then goes to get treated. Treating the sewerage is protecting the environment and this is why it’s important to maintain sewer lines and the system. But what do you do when you encounter sewage problems like blocked sewers?

A blocked sewer is a major health problem, leading to unpleasant odours and even cause flooding. You do not want untreated sewerage water flooding into your yard. If you suspect your sewer is clogged, contact our qualified plumbers at The Blocked Drain Guys immediately. We will diagnose the problem and make the necessary repairs.

The most common causes of a blocked sewer are tree roots, debris, and broken or collapsed pipes. Sometimes it is required to excavate the area to clear the blockage depending on the sewer system condition. Need to unblock your sewers or blocked drains? Call us before the blocked drain gets worse! Say Goodbye to Blocked Drains…

We had a blocked sewer and Craig from The Blocked Drain Guys came out straight away. He was fair, honest, kind, and cleared the problem quickly. Highly recommend them for fast and efficient service – thank you Craig! For context, before calling Craig we had contacted another company (Dans Plumbing). While they partially cleared the blockage, they then tried to pressure us into unnecessary “repairs” with a ridiculous $17,000 quote, making false claims about damaged pipes. We refused, but still had to pay $1,250 for their overpriced call-out. In the end, Craig solved the issue properly without the nonsense. If you want genuine service without being ripped off, go with The Blocked Drain Guys.

Craig was fantastic to deal with from start to finish. He was incredibly patient, took the time to explain everything clearly (and I had a lot of questions!), and made sure I fully understood what was going on. His work was super thorough, and he managed to clear my blocked drain on the same day—which was such a relief! On top of that, his pricing was very reasonable, especially for the quality of service provided. I’m so grateful and will definitely be using Craig as my go-to plumber from now on. Highly recommend to anyone looking for a plumber they can trust!

The team came out to check on our drainage, found roots in the pipes and fixed that up for us. Professional and efficient work, resonably priced. Give them a call to discuss your work.

Blocked Sewer FAQs

Common questions about blocked sewers answered by Sydney drainage experts

Common signs include multiple drains backing up at once, gurgling sounds from toilets or drains, sewage odors, water pooling in your yard, or toilets that won’t flush. If more than one fixture is affected, it’s usually a sewer blockage rather than a single drain issue.

Tree roots are the most common cause in Sydney, especially in older properties with terracotta pipes. Other causes include flushed wipes, grease buildup, collapsed pipes, ground movement, or foreign objects. We use CCTV cameras to identify the exact cause and location.

Yes. Tree roots seek moisture and nutrients from sewer pipes. They enter through tiny cracks or joints, then grow inside the pipe until they create a complete blockage. Figs, willows, and camphor laurels are particularly aggressive. Once roots are in, they’ll keep growing unless the pipe is relined or replaced.

Sewer clearing typically costs $250-$600 depending on the blockage location and severity. Simple blockages near the house are cheaper. Blockages deep in your sewer main or caused by tree roots may require jetting or relining. We provide upfront quotes after camera inspection.

Only if the underlying issue is addressed. If your sewer is blocked by tree roots or collapsed pipes, clearing it provides temporary relief but the problem will return. We recommend CCTV inspection to identify damage, then pipe relining or targeted repairs for a permanent fix.

You’re responsible for the sewer pipe from your house to the property boundary. Sydney Water is responsible from the boundary to the street main. If the blockage is on your side, it’s your cost. We can help identify where the blockage is located.
