Drainage Killara: Blocked Drains, Sewer Lines and Stormwater, Sorted Properly
1000+ five-star reviews
Water has one job on a property: get where it's meant to go, then leave. When that stops, everything else follows: the gurgling shower, the smelly floor waste, the pit flooding beside the garage in a storm.
This page is the drainage hub for Killara. It covers everything from a slow kitchen sink to a sewer line that needs renewing under a heritage garden. Every service below has its own page with the full detail, written for these specific houses, slopes and soils.

When to call about drainage, and for what
Not every slow drain needs a plumber today, but some symptoms shouldn't wait. Use this as a rough router:
One fixture draining slowly
Usually a local blockage; the blocked drains page covers diagnosis and clearing.
Multiple fixtures gurgling or backing up at once
That's the sewer line, and it moves from nuisance to urgent fast; see blocked sewer.
Water pooling around grates, pits or the base of a slope during rain
A stormwater problem, covered under stormwater.
The same drain blocking again and again
A structural fault, and the point where CCTV drain inspections earn their keep.
A known or suspected cracked line under a garden, driveway or heritage planting
Pipe relining renews it without excavation.
New drainage needed entirely, or an old line beyond repair
That's drainage repair and installation.
If water is actively entering the house, don't wait: the emergency plumbing hub lists the make-safe steps to take while a plumber is on the way.
Roots, ridges and century-old clay: why drainage here is different
The suburb was planted on purpose
And the lines are old
That's why our drainage work leans on the camera before any recommendation. Guessing is how gardens get dug up for nothing, and how the same blockage returns by spring.
The six drainage services, each with its own page
Drainage repair and installation
New lines, replaced lines and repaired lines, planned and quoted before any digging starts.
Blocked drains
The everyday blockage, cleared, then traced to its cause so it stays clear.
Blocked sewer
The main line backing up, handled with urgency and the right equipment.
Stormwater
Rainwater management for sloping, wooded blocks, from pits to surface channels.
CCTV drain inspections
The camera that turns guesswork into a recorded, precise picture of the line.
Pipe relining
A renewed pipe inside the old one, no excavation of gardens, driveways or heritage plantings.
Autumn leaves, summer storms: a garden suburb's drainage calendar
Drainage work here follows the seasons more visibly than most trades. Through late autumn, the canopy drops its leaf litter into gutters, grates and stormwater pits. The debris washes downslope into pits that were often sized decades ago for a different climate.
Then through the warm months, thunderstorm downpours arrive in bursts the older pits can't take, and water ends up where it shouldn't be.
The practical rhythm we see is a flush of blocked-drain calls after the first big autumn drop, then stormwater callouts clustered around the first serious summer storm. Owners who book a pit clear and grate check between those two seasons tend to meet neither.
What each drainage service covers
Drainage repair and installation
New lines, replaced lines and targeted repairs: a stormwater line for a subdivided block, an ag-line regraded behind a retaining wall, a collapsed earthenware section cut out and swapped for PVC. On ground that falls from the ridgeline toward the valley, fall and capacity get calculated, not guessed.
Blocked drains
The most common drainage call in the suburb, and the one with the most common hidden cause: roots. Clearing is half the job; explaining why it blocked is the other half. Jetting does the clearing, the camera does the explaining, and you finish knowing which of the two yours needed.
Blocked sewer
When the main line backs up, multiple fixtures gurgle, the floor waste rises and the smell arrives, this is the page. A blocked sewer on a large block with mature trees gets urgency, the right clearing equipment for the pipe, and an inspection afterwards so the cause goes on record.
Stormwater
Rain that can't get away fast enough on a sloping, wooded block finds garages, under-house spaces and driveways. Pits, grates, surface channels, ag-lines and downpipe connections all live here, sized to the block's real catchment and fall. It's the difference between a storm that passes and one that leaves a mess.
CCTV drain inspections
The camera travels the line and records exactly what's there: root intrusion at a joint, a fractured earthenware section, a sag holding debris. Before buying an older home here, before choosing between clearing and relining, the inspection turns the decision from opinion into evidence.
Pipe relining
When the camera reveals fractures or a root mass inside the line, relining renews it in place: a resin-sleeved liner is pulled through the old pipe and cured, leaving a seamless new pipe inside the old one. For a heritage garden, it's the fix that saves what a dig would destroy.
How it works
How we diagnose a drainage fault: camera first, then the right fix
The diagnostic path matters because the wrong order wastes money. It runs:
- 01
Hear the history first
Which fixtures, how often, whether it follows rain or heavy use. The pattern narrows things down before any gear leaves the van.
- 02
Put the camera down the line
A CCTV drain inspection shows the pipe's interior, where the fault sits and what state the whole run is in, recorded so you see exactly what we see.
- 03
Clear it the thorough way
Water jetting scours roots, grease and silt off the pipe wall instead of boring a tunnel through the middle of the blockage, which is all a shortcut ever achieves.
- 04
Recommend the fix that lasts
A sound pipe that blocked once stays cleared. A fractured or root-filled line gets an honest call: targeted repair, replacement, or relining where digging would cost more than the pipe.
Nobody here pays for excavation before a camera has proved it necessary. Where the garden matters as much as the house, that discipline is the service.
Signs by property type across the suburb
Federation and inter-war houses. Original earthenware runs are the story. Watch for the same fixture blocking again and again, a lawn patch staying greener than the rest, a faint sewage smell near a side path. These lines crack at joints over decades, and the lasting answer is usually relining or section replacement, not another clear.
Post-war and 1960s-1980s homes. Earlier clay or early PVC with weaker joints, plus stormwater built for smaller storms. Watch for pooling at the block's low corner after rain, and downpipes dumping against the foundation instead of into a connected line.
Units near the railway and Pacific Highway. Shared drainage concentrates risk: one blocked common line can touch several homes at once. Strata wants the fault documented properly for the owners corporation, and a camera report does exactly that.
Larger blocks backing bushland. Properties on the valley interface cop overland flow from upslope as well as their own roof water. Pit capacity and surface grading need checking together, which is the stormwater page's territory.

What Killara's trees, soil and storms mean for drains
The soil
The trees
The storms
None of this makes drainage here a run of bad luck. It's a system under constant root pressure and periodic water load, and the homes that stay trouble-free are the ones that have had the lines inspected once, know their condition, and have matched the fix to the fault.

What drainage work costs, and how it's priced

- Card, cash and payment plans accepted
No surprises, no obligation. If the price doesn't work for you, you owe us nothing.
Drainage pricing specifically: a clear, a camera inspection, a targeted repair and a full reline are four very different jobs. The only honest way to price any of them is after the diagnosis, which is why the inspection comes first and the written price follows it.
Where we work
Where this fits alongside our other work
A drainage fault often travels in company. A surcharged gully trap can look like a burst pipe until the rain stops and the water goes with it. A damp wall that seems like a drainage issue can be a hidden leak, which is where leak detection settles it.
Some drainage faults escalate. A blocked sewer that backs up into the bathroom can tip into an overflowing toilet at 2am, and that page opens with the first-minute moves. For everything that isn't water in the ground, the plumbing hub covers the fixtures, and the hot water hub covers the system in the corner of the garage.
The neighbours are covered too. We work the surrounding Ku-ring-gai suburbs, including Gordon and Lindfield, with the same drainage crew and the same camera-first approach.
Good questions, straight answers
Drainage questions Killara locals ask
Why do drains block so often in this suburb?
The dense canopy over large garden blocks pushes roots into ageing earthenware lines, and the ridge-to-valley fall concentrates runoff and debris in the downslope drains, so blockages here usually have a structural cause rather than a one-off trigger.
How do you tell a blocked stormwater drain from a blocked sewer?
A blocked stormwater drain shows up in rain, with water pooling around pits and surface grates, while a blocked sewer smells, backs up inside fixtures and gurgles when you run water, and a camera inspection confirms which line is involved.
Is there a way to renew a root-riddled line without digging up the garden?
Yes, relining pushes a resin sleeve through the existing run and cures it in place, leaving a seamless pipe with nothing for roots to grab, which matters on heritage blocks where excavation would do more damage than the roots ever did.
How often should stormwater pits be cleared on a leafy block?
On blocks under heavy canopy, a single clear each year once the autumn drop has finished is usually enough, plus a check before the summer storm season so the pits handle a downpour instead of spilling it.
Do you charge a call out fee to look at a blocked drain?
No, the call out fee is $0, and you receive a fixed written price for the complete fix before any work begins, so you can make the decision with the full picture in front of you.
Does a relined pipe last as long as a brand new one?
A cured liner is a seamless pipe in its own right, with nothing for roots to enter and a service life comparable to new pipe, while sparing driveways, gardens and heritage plantings from excavation.
What are the signs a sewer line needs replacing rather than clearing?
The same run blocking twice in a year, multiple slow fixtures at once, damp patches or sinkage over the line, and a camera showing collapsed or badly fractured earthenware all point to replacement or relining rather than another clear.
