A blocked drain in Thornbury can go from a slow gurgle to a backed-up sink or flooded bathroom fast. Sedcon Plumbing provides same-day blocked drain clearing across Thornbury, Northcote, Preston and the inner north — with the right equipment to fix it properly the first time.
Signs You Have a Blocked Drain in Thornbury
- Water pooling around shower or sink drains — slow drainage is the first warning sign
- Gurgling sounds from pipes — air trapped behind a partial blockage
- Sewage smell from drains — decomposing debris or a vented blockage below the trap
- Multiple fixtures draining slowly — points to a main sewer line blockage rather than a single fixture
- Toilet bubbling when you run the sink — a classic sign the main drain is partially blocked
What Causes Blocked Drains in Thornbury Homes?
Thornbury has a strong mix of Californian bungalows, interwar homes and post-war brick veneers — many with original clay or terracotta drain pipes that are over 60 years old. These are the most common causes we see:
- Tree root intrusion — Thornbury’s mature street trees and garden plantings send roots into ageing pipe joints, cracking them open and causing recurring blockages
- Grease and fat build-up — kitchen drains in older homes often lack adequate fall, causing fat to accumulate on pipe walls
- Collapsed terracotta pipes — decades of ground movement and root pressure can crack or collapse older pipe sections
- Foreign objects — wipes, hygiene products and food debris flushed or rinsed down drains
- Deteriorated pipe joints — old rubber or cement joints that have broken down over time
How We Clear Blocked Drains in Thornbury
We don’t just push the blockage further down the pipe — we clear it completely and check what caused it:
- Drain snake / electric eel: For soft blockages — grease, hair, debris — we use a motorised drain snake to break through and clear the obstruction
- High-pressure water jetting: For stubborn build-up, roots or hardened grease, hydro-jet clearing scours the pipe walls clean
- CCTV drain inspection: If the blockage is recurring or the cause isn’t clear, a camera inspection shows exactly what’s inside the pipe and where the problem is
Do You Need Pipe Relining or Replacement?
If CCTV shows cracked, root-invaded or offset pipe sections, clearing the blockage is only a temporary fix. Pipe relining installs a new structural liner inside the existing pipe — no excavation, no damage to your garden or driveway. It’s the preferred solution for Thornbury’s older pipe network and typically costs significantly less than excavation and replacement.
Frequently Asked Questions — Blocked Drains Thornbury
How quickly can you get to Thornbury?
Same day in most cases. Call before noon and we’ll usually be there the same afternoon.
How much does it cost to unblock a drain in Thornbury?
Simple blockages typically cost $180–$350. Hydro-jetting starts around $350. Prices are confirmed before we start.
Will you need to dig up my yard?
Not for clearing a blockage. Excavation is only needed for pipe replacement — and pipe relining is usually a better, cheaper alternative for older Thornbury pipes.
What if the blockage comes back?
Recurring blockages almost always have an underlying cause — roots, broken pipe, inadequate fall. A CCTV inspection finds it so we can fix the actual problem, not just clear the symptom.
