Drainage Done Once, With the Cause Fixed and the Yard Left Intact
Trenches, relines and renewals across Normanhurst start with a camera, not a guess. Call (02) 9072 0520 and a licensed plumber will trace the fault, quote the whole job in writing and leave the yard as they found it. The wider drainage picture sits at /drainage/.
Where the Bush Meets the Back Fence
- Gullies at the back fence Blocks backing onto the Berowra Valley reserve system fall steeply toward bushland gullies, and drainage runs crossing that drop carry runoff the original builders never sized for. We rebuild those runs to handle the fall rather than fight it.
- Shale and rock underfoot Excavation here meets Hornsby Plateau shale sitting over rock, which is exactly why we arrive with cutting equipment and a camera locate first, so the trench is dug once, and only where it genuinely must be.
- Canopy overhead Mature street trees and bush-edge vegetation push fine roots through ageing pipe joints, so a repaired line only stays fixed if every entry point is sealed properly, not merely cleared and left waiting.
Drainage Repairs and Installations We Complete
Every job starts below ground and ends with a yard showing no sign of it: these are the repairs and installations we complete most often around the Federation blocks and the newer brick infill alike.
Sewer line renewal
Cracked earthenware sewer lines beneath Federation and inter-war homes are excavated back to sound pipe and rebuilt in modern PVC, restoring a fall that carries waste reliably and sparing households the repeat blockages a patched clay joint keeps on inviting. Where the run is a candidate for pipe relining instead, we will say so.
Stormwater repairs
Sloping blocks shed runoff toward the Berowra Valley gullies, so we rebuild stormwater lines, pits and junctions that downpours have surcharged or split, sizing each run for the volume a plateau ridgeline actually sheds during one genuinely heavy summer storm.
New drain installation
Bathroom and kitchen renovations, granny flats and pool builds all need new drainage laid at correct grades, and we trench through the local shale and rock, bed the pipe properly and connect it to the sewer with Sydney Water approvals handled.
Excavation and reinstatement
Where a repair means opening the ground, we dig only the section that failed, hand-excavate around gardens and footings where access is tight, then reinstate lawns, paths and driveways so the finished job leaves no trace of the original trench.
The Calendar Works Against These Pipes Too
The same drainage systems face a different test each season, and it shapes how we repair them:
- Autumn Heavy leaf fall from the dense canopy washes into gutters, pits and stormwater grates, so a line that was already marginal clogs right as the wet months arrive. A pre-summer clean of pits and grates is money well spent.
- Summer Intense downpours on the ridgeline surcharge older stormwater connections, and the weak point, whether a split joint or an undersized run, shows itself exactly when you least want it to.
- Winter Saturated shale ground moves more than dry ground, and movement is what finishes off earthenware pipes that have been slowly cracking for years.
Common Drainage Problems We Fix
Recurring sewer blockages
A sewer that blocks again within months of a clean usually means roots have found a cracked clay joint, and clearing the choke without repairing the pipe simply books the same call for next season. A proper CCTV inspection settles it.
Collapsed clay joints
Ground movement and decades of load crack earthenware pipes until sections sag or collapse outright, and a camera inspection shows exactly which run needs renewal before the dig starts, so you are never quoted blind. Serious backups need the blocked sewer team fast.
Surcharging stormwater
Heavy rain on the ridgeline pushes older stormwater lines past capacity and water backs up through gullies toward the house, and upsizing the run or adding an overflow path fixes the cause rather than mopping the symptom. See our stormwater service for the full picture.
Why Fixing It Properly Matters: The Case for Acting Now
- Water damage compounds quietly A leaking drain under a house or behind a wall softens footings, feeds timber rot and attracts termites, and the repair bill grows every month the pipe keeps leaking into places you cannot see.
- Early faults stay affordable faults A cracked joint caught on camera is a localised repair; the same joint left another few winters can collapse a run and turn a half-day job into an excavation across half the yard.
- Compliant drainage protects the sale Documented, properly certified drainage work is one less defect for a building inspector to flag, and it is the kind of paperwork owner-occupiers here tend to hold onto for decades.
How it works
Our Repair 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
Repair, reline or renew
With the diagnosis on camera footage, we lay out the honest options, from a targeted excavation to pipe relining that seals the failed run without trenching the whole yard, and you choose the path before anything begins.
- 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 Normanhurst
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 Normanhurst 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 Around the Plateau
We cover Thornleigh, Hornsby, Wahroonga, Pennant Hills and Waitara too, with the same camera-first diagnosis and fixed pricing, and because our vans work the Upper North Shore, a drainage job in a neighbouring street is never a long trip.

Good questions, straight answers
Drainage repair questions Normanhurst locals ask
How do I know if my drain needs repair rather than just clearing?
Repeat blockages, gurgling fixtures and wet patches along the line usually point to cracked or root-invaded pipe, and a CCTV inspection shows whether a repair or a full renewal is the honest answer.
Do older homes here always need their clay drains replaced?
Not always, because intact earthenware runs can be kept and patched sections relined, but homes from the Federation and inter-war eras often have enough joint failure that renewing the worst runs is the economical path.
Will you have to dig up my whole yard?
Rarely, because camera locating pinpoints the failed section so we excavate only what genuinely needs renewing, and where conditions suit, pipe relining seals the existing pipe from inside without trenching at all.
What does drainage repair cost?
Every job is quoted as a fixed written price after the camera inspection, with a $0 call out fee, so you see the full cost and approve it before any digging or repair work starts.
Can you work around Sydney Water requirements?
Yes, because work that touches the sewer main or needs approvals is handled with Sydney Water from the start, and the compliance paperwork arrives with the invoice so your records stay complete.
Is the work guaranteed?
Every repair and installation is covered by our Lifetime Labour Warranty, so if a joint, run or reinstated surface fails because of our workmanship, we return and make it right at no cost.
