If you live in one of the older weatherboards or Californian bungalows around Coburg or Pascoe Vale, there's a good chance you've had at least one blocked drain in the last few years that seemed to come out of nowhere. It's not bad luck. It's the plumbing underneath streets that were laid out 60, 70, sometimes 90 years ago, running under some of the biggest street trees in Melbourne's inner north.
We get called out to these two suburbs constantly for the same root cause literally. Tree roots find their way into old clay and earthenware pipe joints looking for moisture, and once they're in, they spread fast. A drain that was running fine in summer can be fully blocked by autumn once the roots put on a growth spurt chasing groundwater.
Old pipes, big trees: the Coburg and Pascoe Vale combination
A lot of the housing stock here predates PVC plumbing entirely. Original clay pipes were never designed to handle 80 years of root pressure, ground movement, and the odd renovation that's tied a new stormwater line into an ageing system without anyone checking what it was connecting to. Add in the elm and plane trees lining streets like Nicholson Street or around Coburg Lake, and you've got root systems actively working their way toward the nearest source of water which is often your sewer line.
Pascoe Vale has a similar story, just with slightly younger housing in parts and a similar tree canopy. The result is the same: gurgling toilets, slow-draining showers, or that unmistakable smell near an outdoor drain that tells you something's wrong below ground.
The signs before it's a full blockage
Most people wait until a drain is completely blocked before calling anyone, but there are earlier signs worth acting on:
-
Water draining slower than usual in the shower or laundry sink
-
Gurgling sounds from the toilet after you flush
-
A damp patch or unusually green section of lawn near where your sewer line runs
-
A faint sewage smell outside, especially after rain
Catching it at this stage usually means a drain clear rather than an excavation.
What actually fixes a tree root blockage
A standard drain snake will punch a hole through roots temporarily, but they grow back through the same gap within months if that's all that's done. We run a CCTV camera down the line first to see exactly where the intrusion is and how bad the pipe damage is, then decide between a high-pressure jet clear (which cuts roots back properly) or, if the pipe itself is cracked or offset, a relining or section replacement. Jetting alone solves most cases we see in Coburg and Pascoe Vale without needing to dig up a driveway or a garden bed.
When it's worth getting ahead of it
If your place is on one of the older streets and you've had one root-related blockage already, it's almost certainly not the last one unless the section gets relined or replaced. A CCTV drain inspection before you're standing in a flooded laundry gives you a heads-up on how much pipe is affected and what your realistic options are, rather than making that call during an emergency.
FAQs
How do I know if my blocked drain is caused by tree roots? Gurgling toilets, slow drainage across multiple fixtures at once, and green patches over your sewer line are the classic signs. A CCTV camera inspection confirms it in about 20 minutes and shows exactly where the roots have entered.
Can tree roots be removed without cutting the tree down? Yes. High-pressure water jetting cuts roots back inside the pipe without touching the tree itself. The tree stays, the pipe gets cleared — though if the entry point is a cracked joint, that section may need repair to stop regrowth.
How much does a blocked drain call-out cost in Coburg or Pascoe Vale? It depends on access and severity, but a standard drain clear is a straightforward same-day job for most homes in these suburbs. We give you a fixed price before starting, based on the CCTV findings.
Is this covered by insurance? Generally no for gradual tree root damage, though sudden pipe collapse sometimes is. Worth checking your policy, but budget for it as a maintenance cost rather than relying on a claim.
How often should older homes get their drains checked? If you're on a tree-lined street with original clay pipes, every 2-3 years is a sensible interval for a CCTV check, even with no obvious symptoms yet.
