Penshurst is known for its federation and interwar homes, many on generous blocks with established gardens, spread either side of the railway and King Georges Road. Plenty of those houses have been lovingly restored above ground. Below ground, the pipes are often a lot older than the renovation. St George Blocked Drains is a local referral service. We connect Penshurst homeowners with licensed local drain plumbers we work with.
Why Penshurst drains block
Older homes in Penshurst commonly still run earthenware clay sewer lines. Clay pipe itself lasts well, but it was laid in short lengths with mortar or rubber ring joints, and after many decades of ground movement and soil shrink and swell, those joints separate. Moisture leaks out, roots follow it in, and a fine root mass grows inside the pipe until paper and waste catch on it.
Penshurst's mature trees make this more likely. Large gardens and leafy streets put a lot of roots within reach of the sewer line, and some of the worst blockages come from trees in the neighbour's yard rather than your own.
Restorations bring another issue. When an old house gets a new bathroom or kitchen, the new plumbing often connects into the original line. That junction, and any old pipe that has sagged under extensions or paths, is a frequent trouble spot.
What clearing a blocked drain involves
The licensed drain plumbers we work with typically clear the line first, then send a CCTV drain camera through to check its condition. In an older Penshurst home that footage is the most useful thing you can have, because it shows whether you have a one-off blockage or a pipe that will keep blocking. For tree roots in drains, jetting with a root-cutting nozzle shears them off at the wall, and if the clay is cracked, pipe relining seals it without lifting a period garden or front path.
A standard clear typically costs $150 to $400, root clearing $250 to $600, and a camera inspection $249 to $600. Relining typically costs $3,000 to $8,000 or more depending on the length of the damaged run.
Frequently asked questions
We are restoring a federation home. Should we check the drains?
Yes, ideally before landscaping or new paths go in. A camera inspection shows the pipe route and condition while it is still cheap to fix anything found.
Can relining go through old clay pipe with lots of joints?
Usually, provided the pipe has not collapsed. The liner forms a jointless pipe inside the old one, which also stops roots getting back in.
The roots are coming from next door's tree. Who pays?
The pipe on your property is generally your responsibility. If the fix is significant, talk to your neighbour, and the camera footage helps that conversation.
