A real person answers, day or night
Broken drains rebuilt right, on the kind of ground that never quite sits still
Ring (02) 9072 0502 and a licensed plumber will look before lifting a shovel, because a drain laid poorly into loose sand fails twice as fast as one bedded and graded properly the first time.
Why replacing a drain here starts with the water table
Wet trenches, not dry ones
Fill that will not hold a shape
Our drainage repair and installation services
Rebuilding and installing drainage on filled ground takes method rather than guesswork, so here is the range we handle for local cottages, apartment blocks and low, wet yards, every job carrying a fixed written price:
New drain lines
Fresh pipework for a renovation, granny flat or extension is set out and laid to a calculated fall, then pressure tested end to end, so the finished line drains reliably long after the paving and turf have gone over it.
Collapsed line renewal
A run that has fractured, dropped at a joint or caved right in under the shifting fill gets dug out and replaced with modern PVC, so you are not paying to reline a pipe already too far gone to save.
Trench and bedding
Because the excavation meets groundwater within a metre or two, we shore the walls, pump the hole dry and lay the new pipe on imported gravel, giving it the firm support that the loose native sand simply cannot offer alone.
Grade and fall
Set to the correct gradient from the outset, a drain across this flat basin keeps the self-cleansing velocity it needs instead of ponding, which is exactly why an eyeballed fall on low ground so often silts up and blocks later.
The cottage drains and the tower drains need different plans
Earthenware under the old semis
Shared lines beneath the blocks
Common drain-replacement problems on low ground
Recurring collapse
A line that keeps blocking at the same spot despite repeated clearing is usually a pipe deforming under the soft fill, and only excavating and renewing that section actually ends the cycle rather than buying you another few weeks.
Roots at the joints
Perished earthenware joints under an older yard draw fine roots that lift and crack the pipe, so replacing the failed length with sealed modern fittings shuts the roots out for good instead of clearing them again each spring.
Water in the trench
Groundwater pouring into an open dig is not a delay to push through but a job to manage properly, because a pipe laid into an unpumped, unshored trench settles unevenly and loses the fall it was meant to keep.
Why a proper renewal is worth doing once
Putting off a failing drain rarely stays a small job, and on ground this soft the damage compounds quietly underneath long before it shows at the surface, so here is what a sound renewal protects:
Stop the ground washing away
Protect the slab and the footings
Buy decades, not a season
How it works
How a drain replacement works, step by step
- 01
Call and tell us
Ring (02) 9072 0502 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
Dig, lay and reinstate
With the price agreed, we shore and dewater the trench, lay and bed the new line to its proper fall, run a camera through to confirm the drain sits true, then backfill, compact the ground and make the surface good again.

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 Mascot
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 Mascot 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
New and replacement drainage is work we carry right across the wider Bayside coast, from Botany and Rosebery through Eastlakes to the riverside towers of Wolli Creek and the canal-side streets of Tempe, all on the same soft, low-lying ground.
Good questions, straight answers
Drain repair questions Mascot locals ask
Do you have to excavate the whole yard to replace a drain?
Not usually, because a camera run pinpoints the failed section first, so we open only the ground directly over the fault rather than trenching the length of the property.
Why is laying a drain here trickier than on higher ground?
The trench meets groundwater from the Botany sand beds barely a metre down, so the pipe must be bedded, shored and pumped dry while it is laid to hold its fall.
Can you renew the old earthenware drains under a period cottage?
Yes, we dig out brittle earthenware branches that have dropped and cracked under the shifting fill off Botany Road and lay modern PVC set to a proper self-cleansing gradient.
How long does a new drain last once it is installed?
A correctly graded PVC line bedded on stable gravel will drain a property reliably for decades, which is the whole point of doing the bedding and fall right the first time.
Do you handle drainage renewals in a strata apartment block?
We do, tracing shared common-property runs and pump-out lines through the basement and coordinating the dig and access with the building manager before any slab is lifted.
What does a drainage repair cost to get started?
The call out fee is $0 and your plumber puts a fixed price on paper before any work starts, so the assessment and quote never cost you a thing.
