Water moving downhill is only a problem when nobody designed where it ends up
This suburb sits high, and that is its stormwater blessing and its curse.
- Rain gathers speed On blocks with long falls toward the gullies, water arrives at the low side fast and hard, hunting out garden beds, footings and the fenceline next door.
- Ageing lines lose the contest Runs laid decades ago were sized for a gentler climate and shallower roofs, not the volume a summer downpour delivers off an elevated plateau.
We design and repair stormwater systems that give that water a controlled path. Call (02) 9072 0504 and talk it through with a licensed plumber.
Stormwater on a plateau that drops away fast
The terrain writes the job brief
The ground makes it worse
The runs we build here are staged, graded and bedded for the drop, engineered for the terrain rather than copied from a flat-block template.
Our stormwater services
Four streams of work cover everything a local stormwater system needs, from the grate at the gully to the outlet at the boundary:
Steep-block stormwater design
We design stormwater runs for properties that fall sharply toward the creek gullies, sizing pipes and pits for the volume a plateau storm actually delivers and carrying water away in controlled stages instead of letting it scour the yard.
Pits, gutters and gullies
Most local blocks rely on original stormwater pits and gully grates that have silted up or cracked apart, and we rebuild them with properly bedded bases, sealed lids and grates sized to catch what your roof and yard shed.
Downpipes and roof water
Roof water dumped beside footings is the quiet destroyer of older brick homes, so we reconnect downpipes into proper dispersal lines, extend outlets away from foundations and stop the constant wetting that reactive clay ground punishes back onto your brickwork.
Surcharges and overloads
When heavy rain overwhelms undersized lines, water backs up through gullies and low points, and we relieve the overload by upsizing runs, adding relief pits and redirecting flows so the next downpour has somewhere to go besides your lawn.
When summer storms race off the ridge
Locals know the pattern
Leaf litter loads the pits
Cut-and-filled ground settles unevenly
Our stormwater work accounts for all three patterns, and we hold the parts and pit components to fix them on the first visit wherever possible.
Common stormwater problems we fix
Two problems bring us out to local blocks more than any others, and both get worse every wet season they are left alone:
Gully surcharge after storms
Downpours funnelling off the ridge can push water back up through gully traps on downhill blocks, and while it looks like a blocked drain it is usually a capacity problem, which we fix by enlarging or rerouting the affected runs.
Silted and collapsed lines
Decades of silt, leaf litter and garden soil wash into older stormwater lines until they hold almost nothing, and where a section has collapsed outright we excavate and replace it, or reline the run where digging is impractical.
If the blockage turns out to be in the sewer rather than the stormwater, the symptoms and the fix differ, so start with our blocked drains service before assuming which system is at fault.
Why acting on stormwater matters
Stormwater failure is slow damage, which is exactly why it gets ignored until the repair costs triple. Three consequences drive most of our callouts:
Scour and erosion
Uncontrolled run-off carves channels through gardens and washes soil from beneath paths and retaining walls, and the ground that disappears never announces itself until something above it drops.
Foundation wetting
Water ponding against footings keeps reactive clay moving, and the cracking that follows in brick and brick-veneer walls costs far more than the stormwater line that caused it.
Neighbourhood flow
On steep streets, one property's mismanaged run-off becomes the downhill neighbour's flood, and fixing the whole path rather than one section is what actually ends the problem.
How it works
Our stormwater process, step by step
- 01
Call and tell us
Ring (02) 9072 0504 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
Diagnose and design
We trace the existing runs, test their falls and outlets, and map where water is actually going on your block. A CCTV drain inspection often does this tracing cleanly, showing the run's condition before we commit to any excavation.
- 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 Hornsby Heights
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 Hornsby Heights 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
Our stormwater and drainage work covers the whole plateau district, from Mount Colah and Galston across to Mount Kuring-Gai, Asquith and Hornsby, and every one of those suburbs shares the same steep-fall, bush-edge drainage challenges that make engineered stormwater the only approach worth paying for.

Good questions, straight answers
Stormwater questions Hornsby Heights locals keep asking
Is stormwater separate from the sewer in most local homes?
Yes, and confusing the two causes real damage: the sewer carries wastewater to Sydney Water's mains, while stormwater lines carry rainwater to the street or creek, and each needs its own diagnosis and repair.
Why does my yard flood every time a big storm hits?
On steep plateau blocks, run-off concentrates fast and older lines were never sized for it, so water overwhelms undersized pipes and surcharges gully pits before the system can shed it downhill.
Can a stormwater line be relined instead of dug up?
Often, yes. Where a line is structurally sound enough to host a liner, pipe relining seals cracks and root intrusions from inside the pipe, which suits landscaped yards and hard-to-reach runs along bush edges.
Do stormwater repairs need council or Sydney Water approval?
Most work on private stormwater lines within your boundary needs no approval, but connections that discharge to council street systems or waterways follow Hornsby Shire requirements, and we confirm the rules before any work starts.
How do you find where my stormwater pipes actually run?
A CCTV camera inspection traces the full run from every downpipe and gully, recording falls, joints and faults, so the quote we hand you is based on what your pipes are really doing.
Do you handle stormwater on steep, bush-backed blocks?
Constantly. Properties on the valley edges are our everyday work, and we design staged, engineered runs that carry storm flows down the fall without scouring gardens or undermining retaining walls.
