Drainage Cheltenham: Old Clay, Big Trees, Steep Ground
1000+ five-star reviews
Some suburbs keep plumbers busy with taps. This one keeps them busy with drains, and the reasons are sitting in the ground under every block.
Old clay, big trees, steep ground. The estates around the railway line were drained in earthenware a century back, the blocks are deep and heavily treed, and the eastern side falls into valley bushland. None of that is news to the pipes.
This page is the drainage hub for Cheltenham and the surrounding Hornsby area: every drain, sewer and stormwater service we run, how each is diagnosed, and how pricing works. For the midnight versions of the same problems, the emergency plumbing crew takes the call.

Which symptom points to which service
Drainage faults announce themselves differently depending on which part of the system is failing. Match what you are seeing to the list and you are halfway to a fix:
One fixture gurgles or slows while the rest of the house flows freely
Points to a branch-line blockage: blocked drains.
Sewage smells, a pan bubbling when the washing machine drains, or every drain slow at once
Points to the main line: blocked sewer.
Water pooling in the yard, a pit overflowing near the boundary, or boggy ground after rain
Points to the surface water system: stormwater.
A drain that blocks again within months of being cleared
Needs diagnosis rather than another poke: CCTV drain inspections.
A camera run showing cracked, offset or collapsed sections
Needs a permanent structural fix: pipe relining or a full rebuild through drainage repair & installation.
Why drains behave differently in Cheltenham
Three facts about this suburb shape nearly every drainage job we attend, and all three come from the ground itself.
Earthenware, laid for a different century
A canopy that drinks and hunts
Shale and reactive clay
The six drainage services at a glance
Each of the six services has a dedicated page carrying the full detail: what it covers, how it is diagnosed, and how it is priced.
- Drainage repair & installation: new lines, rebuilds and renewals, from one collapsed section to a full block re-drain.
- Blocked drains: gurgling stacks, slow showers and choking floor wastes, cleared properly and confirmed on camera.
- Blocked sewer: main lines and boundary traps, the blockages that affect every fixture at once.
- Stormwater: pits, surface lines and downpipe runs carrying ridge rainfall away from footings.
- CCTV drain inspections: recorded camera runs showing the fault, its depth and its exact position.
- Pipe relining: a seamless new pipe cured inside the old one, no excavation of driveways or gardens.
Two drainage geographies on one ridge
Geography splits this suburb into two quite different drainage jobs, and we quote them differently because they fail differently.
The valley side
The ridge top
A single block on Boronia Avenue can carry both problems at once, which is why we camera the whole line rather than clearing the first obstruction and calling the job done.
Drainage repairs and new installations
New lines, rebuilds and renewals. From one swapped section to a full re-drain of a deep block, this is the service for drainage that has reached the end of its life. On the oldest properties, fully collapsed clay sections turn up under driveways and garden beds laid decades after the pipes went in.
The honest fix is a properly graded new line, not a patch on a pipe with no wall left. The drainage repair & installation page maps when a rebuild beats a repair and how the work is planned.
Blocked drains, cleared and confirmed
Branch-line faults, jetted clear in one visit. A shower waste slowing, a kitchen sink gurgling, a floor waste backing up after rain: most of these are local blockages, and most are cleared with the jetter on the first call.
The difference is the follow-through, because a camera check after the clear tells you whether that was debris, roots or a collapse waiting to repeat itself. The blocked drains page has the full detail.
Blocked sewer: the main-line job
The whole house knows at once. When the main line chokes, every fixture slows, the stacks gurgle and, in the worst cases, water rises where it should never rise. Century-old trees on deep heritage blocks mean long private sewer runs threaded with roots; repeat clears and relines are the local staple.
This is the job where diagnosis matters most, because clearing the symptom without finding the fault guarantees a return visit. The blocked sewer page covers the process and the permanent options.
Stormwater: rain on the ridge
The surface water system earns its keep here. The ridge sheds hard when it rains, and downpipes, surface pits, spoon drains and the lines behind them are what keep run-off away from footings. Silted pits and broken lines at the bottom of sloping blocks are our most common stormwater repairs.
Each is quoted as a fixed price before we lift a pit lid. The stormwater page covers repairs, new installations and the valley-side surcharge problem.
CCTV inspections: the camera that ended the guessing
A recorded run through the line. Every crack, belly, offset and root mass shows on the footage, with depth and position logged against it. The quote then targets the actual fault rather than a worst-case assumption.
Repeat blockages, pre-purchase checks on older homes and post-clear verification all start here. The CCTV drain inspections page explains the process and what you receive.
Pipe relining: a new pipe inside the old
No digging up the heritage driveway. Where the camera shows cracked or root-bound clay that is still roughly round, a liner is threaded through the damaged section and cured into a seamless new tube, leaving the established garden untouched.
Roots stay out permanently because there are no joints left to invade. The pipe relining page covers which lines suit it, which do not, and how the decision is made.
How it works
Camera, jetter, then the honest decision
Drainage work goes wrong when a plumber clears the symptom and leaves the cause in the ground. Ours runs in a deliberate order:
- 01
Camera first
The line is inspected before anything is done to it, so we know whether the blockage is grease, roots, a belly or a collapse, and exactly where it sits.
- 02
Jet second
High-pressure water clears the line and, on root mass, cuts it back to the pipe wall rather than punching a channel through it.
- 03
Decide third
With the line clear and the recording in hand, the choice is honest: relining for cracked-but-round clay, a rebuild for collapsed sections, maintenance for lines that are simply tired.
- 04
Prove it
A final camera pass confirms the fix, and the recording is yours to keep.
Drain trouble looks different by property type
- Unrenovated heritage houses The original earthenware is still in the ground and still failing joint by joint. Watch for seasonal slow drains, patches of lawn greener than the rest, and a sewer that blocks on a rhythm you can set a calendar by.
- Renovated homes on old drains The kitchen and bathrooms may be new, but the main under the front lawn is a century old. Renovations shift modern water use onto lines never sized for it, and the first sign is usually the floor waste.
- Valley-side blocks Steep runs and heavy run-off mean silt loading and surcharge in big rain. Pits that overflow at the bottom of the block are the early warning, long before water reaches the house.
What the trees and the clay are doing to your pipes
Trees and soil do the slow work that ends in a blocked line, and this suburb has both in unusual measure.
The finest root systems in the business
Why one clear never solves it
The maintenance plumbing crew builds the same logic into an annual visit for pre-1940 homes, and the plumbing hub covers the indoor side of the same old houses. If a drainage fault has already let water into the structure, leak detection finds how far it travelled.

Where we work
Where we work around Cheltenham
Drainage crews run daily across the adjoining suburbs too: North Epping, Beecroft, Epping, Pennant Hills and South Turramurra.
All of them sit on the same shale ridge with the same clay in the ground, and the vans carry the relining and jetting gear for every one. Bookings run through the contact page or straight over the phone.
Good questions, straight answers
Drainage questions from Cheltenham blocks
Why do drains in this suburb block so often?
The old estates were drained in clay over a hundred years ago, and the big gums and mature gardens push roots into every offset joint, so long private runs crack, catch debris and choke.
What is pipe relining, and does it suit an old clay sewer?
A resin-saturated liner is pulled through the damaged pipe and cured into a seamless new tube inside the old clay, which suits cracked, root-bound sections without excavating driveways or established gardens.
Do you clear root-bound sewers after hours?
Yes, because the long private sewers under these blocks choke without warning, and the jetter and camera travel on the van so the line is cleared and diagnosed in one visit, whatever the hour.
How does a CCTV drain inspection work?
A camera is fed through the line and recorded as it travels, logging every crack, belly and root mass with its depth and position, so the repair targets the actual fault instead of a guess.
What does the $0 call out fee cover?
It covers the attendance, the diagnosis and the written fixed quote, so if you decide not to proceed you owe nothing for us turning up, running the camera and telling you what is wrong.
Can stormwater problems on the sloping eastern blocks be fixed?
Yes, because those blocks slope into the valley bushland on the suburb's eastern edge, and we rebuild the pits and lines that surcharge when big rain hits the ridge.
