Blocked drains, cleared properly the first time
Your Plumber Thornleigh clears blocked drains across the suburb with CCTV diagnosis, high-pressure jetting and a fixed written price before any work begins, so you know the full cost up front. Thornleigh homeowners call us first because the blockage gets found, not just pushed along.
A slow drain rarely stays slow for long
A gully that gurgles, a shower that pools, a toilet that fills higher than it should: each one is the drain telling you the line is narrowing. Left alone, a partial blockage packs tighter until the water has nowhere to go but back into your house, usually on the wettest day of the month.
Where we work
What makes drains block around here
The slope feeds the problem. The suburb sits high on a ridgeline, but the blocks fall away into the Larool and Waitara Creek gullies, and run-off from every roof and paved driveway converges into the low-side lines carrying silt, leaf litter and grit with it.
Combine that slope-fed debris with mature canopy overhead and earthenware clay pipework underground, and you get the three blockage drivers we clear here week after week: roots, collapsed clay and silt-packed stormwater.
How it works
How we clear your blocked drain
Every blockage has a cause, and clearing the symptom without finding it guarantees a return visit. Here is the work we do:
- 01
High-pressure water jetting
Jetting blasts root mass, grease and packed silt off the pipe wall rather than poking a hole through it, so the line runs full-bore again. It suits the root-choked clay drains around the creek lines, and the benefit is a drain cleaned properly, not temporarily.
- 02
CCTV drain camera diagnosis
A camera run after jetting shows exactly what caused the blockage, whether roots at a cracked joint, a sagging earthenware section or debris sitting in a misaligned fall. You see the footage, so the benefit is certainty about what your money is fixing.
- 03
Root cutting and pipe repair
Fine root systems that invade through a hairline crack get cut back and the failed joint gets dealt with, either by relining or replacing the section. The benefit is breaking the cycle, because a root-cut without a repair is just a booking for next season.
- 04
Stormwater and gully clearing
Autumn leaf fall from the mature street trees packs gully pits and silt loads the sloping stormwater lines, so we flush pits, jet the runs and check falls. The benefit is a system that copes when a summer storm hits instead of surcharging across the yard.
- 05
Sewer line blockage clearing
When waste backs up through the lowest fixture, the sewer itself is blocked, and we locate and clear it fast, then camera-confirm the line downstream. The benefit is a hygienic, fully cleared sewer and a straight answer on whether the pipe needs further work.

Warning signs a drain is failing
Catching a blockage early is the difference between a jetting job and a dug-up yard. Watch for these:
Gurgling and slow drainage
Fixtures that drain slowly or gurgle when others run mean air trapped behind a partial blockage. It worsens gradually, so booking a clear now avoids an overflow later.
Overflowing gully pits
A gully surcharging outside after rain or during normal use means the line downstream cannot take the flow. Clearing it protects the yard, and the house, from contamination.
Multiple fixtures backing up
When the shower, toilet and laundry all misbehave together, the blockage sits in a shared line. That is a same-day call, because the next flush has nowhere to go.
Why clearing it properly matters
Overflow damage gets expensive fast
Sewer water surcharging into a bathroom or laundry ruins flooring and skirtings, and stormwater flooding a subfloor undermines footings, so acting early protects the structure as well as the hygiene.
Recurring blockages signal pipe failure
A line that blocks every few months usually has roots or a collapsed clay section behind it, and diagnosing the cause once beats paying for a temporary clear four times.
A clean, camera-confirmed drain buys peace of mind
Knowing the line was cleared and inspected, not just rodded, means you can run the washing machine and the dishwasher on the same day without watching the gully.
How it works
Our process, step by step
- 01
Call and tell us
Ring (02) 9072 0520 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Clear, jet and camera-verify
We jet the line to strip the blockage completely, then run the camera from access point to boundary trap to confirm the cause and check the pipe for cracks, roots or misalignment, so the quote for any follow-up repair is based on evidence rather than guesswork.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why choose Your Plumber Thornleigh
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Thornleigh works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Where we work
Areas we service
We clear blocked drains across the suburb and out to the neighbours, covering Normanhurst, Pennant Hills, Westleigh, Hornsby and Wahroonga with the same stocked vans and fixed-price discipline, so wherever the gully gurgles, the local crew is already close by.
Good questions, straight answers
Drain blockage questions Thornleigh locals ask
How do I know if a drain is blocked or just slow?
Water pooling around gully pits, gurgling from floor wastes, and several fixtures backing up together all point to a genuine blockage rather than a single slow fixture, so book a diagnosis.
Why do drains block so often around the creek gullies here?
Mature trees near Larool and Waitara Creeks push fine roots into older clay lines, and the suburb's sloping terrain funnels silt into the low-side drains, so recurring blockages are common.
Will you need to dig up my garden to clear the drain?
Usually not, because high-pressure jetting clears most root and debris blockages from an access point, and we only recommend excavation or relining when the camera shows the pipe itself has failed.
How much does clearing a blocked drain cost?
We inspect the drain, diagnose the cause, and hand you a single fixed written price before any work begins, with a $0 call out fee, so you approve the number first.
Can a blocked drain turn into an emergency?
Yes, because a sewer surcharging into the bathroom or a stormwater line flooding during a storm needs urgent attention, so call us day or night and a licensed plumber will answer.
Do you handle the older clay pipes near the railway station?
We work on earthenware clay drainage in the Federation-era streets near the station constantly, and we camera-locate cracks and misalignments before recommending whether to patch, reline or replace.
