Blocked Drain Repair: What We Actually Do
A clean clears a blockage. A repair fixes the pipe that keeps causing one. This is where we tell you which job you actually need.
What's included:
- Camera diagnosis to locate the crack, collapse or misalignment before any work starts - No-dig pipe relining for cracked or root-cut sections that don't need excavation - Targeted excavation where a collapse or joint failure needs a physical rebuild - Junction and connection-point patches where two pipes no longer meet cleanly - Root removal at the damage site, not just a cut-through that grows back - A final camera pass proving the repair before we leave
When It Is Time for Blocked Drain Repair
A clear that doesn't hold is the clearest sign the pipe itself is broken, not just blocked.
- The same section blocks again within weeks of a professional clean
- Camera footage shows a crack, an offset joint or a visible collapse
- The lawn above the pipe run has started to dip or feels spongy to walk on
- Gurgling or slow drainage keeps coming back at the one fixture
- A damp patch shows up in the yard tracking the line of your drain run
- The same tree roots reappear at the identical spot after cutting
If every fixture in the house is affected at once, that points past a single repair into the sewer line itself. Read our blocked sewer page for that scenario. A repeat blockage with no obvious cause is the job our camera survey was built to answer.
The Thornleigh Angle on Blocked Drain Repair
Thornleigh's housing stock is mostly low-density, detached houses, but the streets around the station and Pennant Hills Road carry a real pocket of unit blocks and townhouses, and shared drain runs behave differently under a strata title.
A private house owns its full pipe run to the boundary. A unit block on Chilvers Road or nearby often shares one line between several dwellings, so a collapse can affect three households at once, not one.
That changes how a repair gets approved and billed. Strata needs the fault located and reported clearly before work starts, which is exactly what our camera pass gives the owners corporation to sign off against.
Blocked Drain Repair Pricing: What Moves the Quote
Every repair quote is fixed and written before we touch a spanner, but a few things decide what that figure looks like.
- The depth of the fault and how much pipe run needs work
- Whether the run sits at an easy boundary shaft or under concrete and paving
- Roots, a full collapse or a shifted joint, each needing a different fix
- Whether a reline or a dig-up is the smarter long-term call for that damage
- One fixture affected, or a shared line serving the whole property
A shared line near Chilvers Road often needs owners-corporation sign-off first.
That can add a step to the timeline even when the fix itself is simple.
Either way, you get the price in writing before anything starts: $0 call-out fee, a free on-site quote. Ask about $50 off when you book online.
Our Blocked Drain Repair Process, Start to Finish
- Camera diagnosis. We run the CCTV drain camera through first and locate the break exactly, no digging blind.
- The price, in writing. You see the footage, we explain the cause, then you sign off on the figure.
- The repair. No-dig pipe relining where it fits, a targeted dig where the pipe has genuinely failed.
- Camera proof. A final camera pass confirms it's proven clear on camera before we leave the job.
Most single-section relines finish within a few hours on-site. A full excavation on a longer run naturally stretches out, and we'd rather tell you that upfront than promise a timeframe that slips.
What NSW Requires for Blocked Drain Repair
Any drain repair work in NSW has to be carried out by a licensed plumber, full stop, whether it's a strata line or a single house. We hold a NSW plumbing licence and Master Plumber accreditation, and every repair job is logged that way.
The private-drain line matters here too. Everything from your boundary shaft in is your responsibility to fix, and that section is what we quote and repair. Past that boundary, the pipe becomes the mains network's territory, and different rules apply to that section entirely.
For strata blocks, common-property drain repairs usually need the owners corporation across the plan before work starts, even when the fault is straightforward. We can put the camera footage in front of a strata manager the same day it's captured.
Why This Is a Job for Our Team
Guessing at a crack from the surface gets pipes patched in the wrong spot. Our plumbers look at the fault directly on screen first.
We quote against what the camera actually found, never against a hunch.
You're never signing off on a price before you've seen the cause, and every repair we make is one we stand behind.

Common questions
Blocked Drain Repair FAQs
Straight answers to what Thornleigh homeowners ask before booking a repair.
Will you show me proof the drain is clear?
Yes. Every blocked drain repair job here finishes with a camera run back through the pipe. You see the same footage we do, proven clear on camera, before we call it done.
How long does blocked drain repair take?
A straightforward crack or joint patch is often finished inside a couple of hours. A collapsed section or a full reline runs longer. We give you the honest range on-site once the camera has shown us what we're dealing with, never a guess over the phone.
Do you offer blocked drain repair in Thornleigh on weekends?
Yes, weekends included. A real person answers the phone day or night, and we guarantee on-site in 30 minutes, because a cracked drain does not wait for Monday.
Do you handle strata or commercial blocked drain repair in Thornleigh?
We do. Thornleigh's unit blocks around the station carry shared drain runs, and a break under common property needs sign-off before work starts. We handle that process and repair the pipe once it's approved.
What equipment do you use for blocked drain repair?
A CCTV drain camera to find the exact break first, then either no-dig pipe relining or a targeted dig, depending on what the footage shows. We never guess at the cause before we've seen it.
Who is responsible if the blockage is in the sewer main?
Everything from your boundary shaft in is our job to repair. Past that point sits the mains network, which is a separate authority's responsibility, and we'll tell you plainly which side of the line a fault sits on.
